Natural Diabetes Cure and Treatment

Diabetes Freedom

It's about time you take charge of your life from the life-sucking diabetes type2 and its so-called heavy medications. With Diabetes Freedom, you have a second chance of doing what you wished you could while nursing the pain and agony from this disease. So get busy living or get busy dying, but don't let this disease be the final report of how you lived your life. Diabetes Freedom is a guide that allows you to reverse diabetes type2. It comprises three simple steps that guide you comprehensively on how to recover without the use of medications, supplements, or pills. All you need to do is follow precisely the guidelines provided. This includes foods to take, time to take, and a specific combination of such foods. Toxins from the food we take as well as the environment can interfere with our body's normal insulin production. The main cause being ceramide toxins, it clogs the pancreas and prevents digestion. Due to this, the body is unable to regulate blood glucose levels resulting in diabetes type2. But through the conversion potential of this program, body detoxification is initiated and toxins eliminated restoring the balance in the body and freeing up the clogged vessels. Read more here...

Insulintreated type 1 diabetics IDDM

Patients must receive exogenous insulin to prevent ketoacidosis. B. Insulin can be given by sliding scale or continuous infusion. 1. Regular insulin 50 U 250 cc NS 0.2 units cc (flush IV tubing before starting). 2. Insulin rate in U hr blood glucose 150 (use 100 as denominator if patient is on steroids, or is markedly obese, or infected). Alternative dosing. 0.1 units kg hr. 3. An IV of D5W (1-1.5 ml kg hr) should be started prior to insulin. 4. Adjust insulin infusion as needed to keep glucose levels between 120-180 mg dL.

Enhanced Insulin Sensitivity

Water soluble compounds extracted from C. cassia potentiate insulin activity, as measured by glucose oxidation in the rat epididymal fat cell assay. The most active compound, methylhydroxy chalcone polymer (MHCP), increased glucose metabolism approximately 20-fold and was an effective mimetic of insulin according to an in vitro study. When combined with insulin, the responses were greater than additive, indicating synergism between the two compounds (Jarvill-Taylor et al 2001). According to Anderson, MHCP is actually a water-soluble polyphenols type-A polymer that increases insulin sensitivity by activating the key enzymes that stimulate insulin receptors, while inhibiting the enzymes that deactivate them. More specifically, extracts of cinnamon activate insulin receptor kinase and inhibit dephosphorylation of the insulin receptor, leading to maximal phosphorylation of the insulin receptor.

Website Summary This article helps readers with diabetes to understand the problem of depression and the risks that having a chronic disease may contribute to any likelihood of experiencing depression. The author notes that depression may occur as a reaction to illness and changing social circumstances, such as after the onset of type 1 diabetes or a divorce, but depression also seems to have a genetic basis in some patients. The author briefly reviews the biological basis of depression, stress hormones, diagnosing

Mechanisms of Premature Aging in Diabetes

The clinical and phenotypic similarities between aging and diabetes suggest that there may be shared biochemical pathways leading to the tissue changes. Glucose is the principal metabolic fuel for many animal species. In general, with few exceptions, the plasma glucose level in various animals is maintained within a narrow range (60-140 mg dl). It is possible that the lower limit of blood glucose levels is determined by the minimum tissue requirements of metabolic fuel, and the upper limit defines the threshold beyond which glucotoxicity limits survival of the species (Mooradian and Thurman, 1999b). Avian species, especially owls and parrots, are the exception to this generalization. These animals have high blood glucose levels in the range of 250 to 350 mg dl and yet have a relatively long life expectancy and show no signs of classical diabetic complications. The overall constancy of blood glucose levels across a wide range of animal species suggests that hyperglycemia, except in...

Changes In Growth Hormone And Insulinlike Growth Factor1 In Hiv Infection

Disturbances in the growth hormone (GH) and insulin-like growth factor-1 (IGF-1) axis have also been described in HIV infection. Decreased levels of IGF-1 have been noted in some malnourished individuals with HIV infection (37,38), but normal levels of IGF-1 were reported in two other groups of patients with prior weight loss (30,39). One potential explanation for these discrepant findings is that the patients in these latter two groups were studied during periods of relative clinical and weight stability, whereas the two former groups included patients who were losing weight at the time of study.

Gsk3 And Insulin Resistance

GSK-3, one of the final regulatory proteins in glycogen production, is an attractive target for non-insulin-dependent diabetes mellitus (NIDDM). In NIDDM biopsy tissue GSK-3 activity is inversely correlated to glycogen synthase activity implicating GSK-3 as contributing to insulin resistance 27,28 . Insulin and insulin receptors are expressed in the brain, including the medial temporal regions that support the formation of memory 29 . Some NIDDM patients are also afflicted with verbal and visual memory decline independent of clinically diagnosed dementia 30 . More recently evidence suggests that the insulin resistance known to underlie NIDDM may also contribute to the clinical symptoms of Alzheimer's disease. GSK-3 intersects these two diseases, and therapeutic inhibition of GSK-3 is indicated for both.

Diabetes And Diabetic Nephropathy

Replacing animal protein with soy protein has been found to improve various disease markers in patients with type 1 or type 2 diabetes and people with obesity. In a RCT of 104 patients with type 2 diabetes, 12 months of a soy-based meal replacement was found to significantly improve weight loss, HbAlc and high-sensitivity C-reactive protein levels and significantly reduce the use of sulfonylureas and metformin compared to the use of individual diet plans (Li et al 2005). Another randomised trial involving 90 obese (non-diabetic) subjects suggests that 6 months on a low-fat, high-soy-protein diet can help to reduce fat while preserving muscle mass and improving glycaemic control and the lipid profile (Deibert et al 2004). studies of diabetic nephropathy. In a controlled crossover trial, 8 weeks of substituting soy protein for animal protein significantly reduced glomerular filtration rates in 12 young adults with type 1 diabetes mellitus (Stephenson et al 2005). In another crossover...

Neonatal Transient Diabetes Mellitus

Neonatal transient diabetes mellitus (TNDM), with an incidence in newborns of 1 400,000 to 1 500,000 (Fosel, 1995 Shield et al., 1997), is characterized by intrauterine growth retardation, failure to thrive, hyperglycemia, glucosuria, dehydration, polyuria, occasional ketonemia and ketonuria, lethargy, and fever. Occasional features include anemia, macroglossia (Figure 1), and umbilical hernia. The diabetic condition may be permanent, subside to recur later as type 2 diabetes (Shield et al., 1997), or vanish completely (Christian et al., 1999).

Diagnosis of gestational diabetes

The diagnosis of gestational diabetes is usually accomplished early in the third trimester of pregnancy. The one-hour glucola test is the screening test for gestational diabetes. Nonfasting women are given 50 grams of glucose in a flavored solution, and their blood is taken one hour after ingestion. If the blood sugar equals or exceeds 140 mg dL, then women are asked to take a three-hour glucose tolerance test (GTT). B. For the three-hour GTT, women are advised to consume an unrestricted diet containing at least 150 grams of carbohydrates daily three days prior to testing. They are asked to fast for 10-14 hours prior to testing. All tests are performed in the morning. Blood is drawn fasting and at 1, 2, and 3 hours postingestion of a 100-gram glucose-containing solution. If any two (out of 4) or more results are abnormal, then they are diagnosed as having gestational diabetes. Criteria for Gestational Diabetes Any two or more abnormal results are diagnostic of gestational diabetes.

Complications of diabetes

Complications may occur in both type I and type II diabetes even with early diagnosis and treatment (Fig 17.3). Insulin dependent diabetics still have a significantly reduced life expectancy. The main causes of death are diabetic nephropathy and vascular disease (myocardial infarction and stroke). Diabetes causes both macrovascular and microvascular complications but microvascular disease is specific to diabetes. Complications are illustrated in Figure 17.3 . Special attention should be paid to the 'deadly quartet' associated with type II diabetes. diabetic nephropathy unnary nfectlon Fig. 17.3 The complications of diabetes

Glycaemic Control And Insulinsensitising Effect

Animal studies have indicated a potential for hypoglycaemic effects when used intravenously. Eleutherens A-G exert marked hypoglycaemic effects in normal and alloxan-induced hyperglycaemic mice (Hikino et al 1986) and eleutherosides show an insulin-like action in diabetic rats (Dardymov et al 1978). However, these effects have not been borne out in human studies (Farnsworth et al 1985) and may not relate to oral dosages of Siberian ginseng. A small, double-blind, randomised, multiple-crossover study using 12 healthy participants actually showed an increase in postprandial plasma glucose at 90 and 120 minutes when 3 g Siberian ginseng was given orally 40 minutes before a 75-g oral glucose tolerance test (Sievenpiper et al 2004). More recently, oral administration of an aqueous extract of Siberian ginseng was shown to improve insulin sensitivity and delay the development of insulin resistance in rats (Liu et al 2005). As a result further trials in people with impaired glucose tolerance...

IRSProteins and Insulin Signaling

Insulin and IGF1 receptors, like the receptors for other growth factors and cytokines, are composed of an extracellular ligand-binding domain that controls the conformation and activity of the intracellular tyrosine kinase 9,10 . Unlike most receptor tyrosine kinases that are activated upon ligand-induced dimerization, insulin and IGF1 receptors exist as inactive covalent dimers composed of two extracellular a-subunits and two transmembrane P-subunits. Insulin and IGF1 bind between the two a-subunits, thus inducing a conformation change that promotes tyrosine autophosphorylation on the cytoplasmic side of the adjacent P-subunits 11,12 . Autophosphorylation occurs in three distinct regions of the P-subunits, including the regulatory loop, the juxtamem-brane region, and the C-terminus. Phosphorylation of three tyrosine residues in the regulatory loop activates the tyrosine kinase by opening the catalytic domain to facilitate entry of adenosine triphosphate (ATP) and peptide substrates...

Insulin Signaling to Glucose Transport

A major, if not the major, endpoint of insulin signaling is the stimulation of glucose uptake (transport) in muscle and fat, the focus of the remainder of this chapter. Currently, at least two distinct pathways (Fig. 3) have been implicated in this process. Both pathways may be required for translocation of the insulin-regulated glucose transporter, GLUT4, a 12-transmembrane-spanning protein, from a vesicular storage compartment (GSV) within the cell, to the plasma membrane. Its insertion makes it competent to transport glucose into the cell (for reviews, see references 10 to 12 ). The most extensively characterized of these pathways begins with the IRS family of proteins (see Chapter 71). Tyrosine phosphorylation of these proteins by the insulin receptor provides recognition sites for Src homology domain 2 (SH2)-containing proteins. Of significance for several pathways in insulin action, including those leading to glucose transport and glycogen synthesis, is the binding and...

Diabetes Type 1 And Type

Orally, gymnema leaf is used to treat both type 1 and type 2 diabetes and hyperglycaemia. There are two clinical trials that suggest that gymnema may be useful in reducing blood glucose levels in both type 1 and type 2 diabetes. In one study the ability of the GS4 extract (400 mg day) to supplement the use of conventional oral hypoglycaemic agents (glibenclamide or tolbutamide) was studied in 22 patients with type 2 diabetes over 18-20 months. Treatment resulted in a significant reduction in fasting blood glucose (174 7 vs 124 5 mg dl_), HbA1c Gymnema sylvestre 675 vs 2.46 0.05 jg hexose mg protein) and raised insulin levels, whereas no changes were observed in the control group. This allowed for a decrease in conventional drug dosage and in five cases, blood glucose homeostasis was maintained with GS4 alone, suggesting that beta-cell function may have been restored (Baskaran et al 1990). In a second study, 27 type 2 diabetes patients were treated with 400 mg of an aqueous extract of...

Insulin regimens for type I diabetes

The most commonly used insulin injection preparations are the 'artificial' human insulins. Insulins are rapid-acting and short duration lispro insulin Starting insulin 2 It is important to use the simplest regimen for the patient and to provide optimal education about its administration and monitoring. Full replacement of insulin is achieved by using 2, 3 or 4 injections per day. Short-acting insulin before breakfast and lunch Intermediate- or long-acting insulin before evening meal Short-acting insulin before breakfast, lunch and dinner Intermediate-acting insulin at bedtime Insulin requirements often vary significantly even in the same individual under different lifestyle conditions. The new rapid-acting analogues can be taken with meals.

Insulin Receptor Domain Structure

The insulin receptor (IR) is a glycosylated, disulfide-linked homodimer, with each monomer being made up of an a-chain that is entirely extracellular and a P-chain that spans the cell membrane once. The a-chain contains the insulin-binding determinants of the receptor, while the intracellular portion of the P-chain includes a protein-tyrosine kinase domain and domains involved in binding signal transduction proteins. The aP monomer of the IR is encoded by a gene with 22 exons alternative splicing of the IR pre-mRNA leads to the tissue-specific expression of two isoforms differing by the presence or absence of a 12-residue segment (exon 11) near the C terminus of the a-chain. The receptor is synthesized as a single chain with a 27-residue signal sequence and is glycosylated, oxidized to the disulfide form, and proteolytically processed to the two-chain form during transport to the cell surface. The mature a-chain of the human IR has 731 amino acid residues, while the P-chain has 620....

The Regulation of GSK3 Activity by Insulin and Growth Factors

In embryonic stem cells that do not express 3-phospho-inositide-dependent protein kinase 1 (PDK1), an essential upstream activator of both PKB and MAPKAP-K1, the PKB-mediated inhibition of GSK3 (induced by insulin-like growth factor 1) and the MAPKAP-K1-mediated inhibition of GSK3 (induced by the tumor-promoting phorbol ester TPA) do not occur 26 . This genetic evidence supports the view that GSK3 can be inhibited by PKB and MAPKAP-K1 in vivo. Figure 1 GSK3 can be inhibited by several different agonists. The inhibition of GSK3 by growth factors, amino acids, and hormones, such as insulin, occurs by a different mechanism than does inhibition of GSK3 by Wnts. Protein kinases that are activated by these agonists, such as PKB, MAP-KAP-K1, and S6 kinase (S6K), phosphorylate the N terminus of GSK3 on a serine residue (Ser9 of GSK3P and Ser21 of GSK3a). In contrast, Wnt signaling does not lead to an increase in Ser9 Ser21 phosphorylation and instead may involve the displacement of Axin and...

The Insulin Like Growth Factor Family

Evidence is accumulating that insulin-like growth factors (IGFs) may play an important role in breast carcinogenesis. The IGF family includes the polypeptide ligands IGF-I and IGF-II two receptors, IGF-IR and IGF-IIR six binding proteins (IGFBP-1 through IGFBP-6) and a large group of IGFBP proteases, which degrade IGFBPs to increase bioactive IGF. The actions of both IGF-I and IGF-II are mediated through IGF-IR, which is located on the cell membrane. The IGFs play an important role in regulating cell proliferation, differentiation, apoptosis, and transformation.62 As a potent mitogen, IGF-I increases DNA synthesis and accelerates the progression of cell division by stimulating the expression of cyclin D1.63

Insulinlike Growth Factor1 Igf1

Overall, the nitrogen-retaining effects of rhIGF-1 in metabolic ward studies did not consistently attain levels seen with rhGH (30), whereas the increases in REE were comparable to those seen with rhGH. Moreover, the insulin-like effect of IGF-1 poses a potential obstacle to its use in patients with HIV-associated wasting, many of whom may be at increased risk of hypoglycemia because of limited energy stores, anorexia, malabsorption, or increased insulin sensitivity (54,55).

Lessons from maturity onset diabetes of the young MODY

As mentioned earlier, a small proportion (around 1 ) of families with diabetes are clearly segregating an autosomal dominant form of early-onset T2D (Frayling et al., 2001). The term ''maturity onset diabetes of the young'' (MODY) was coined to describe these key clinical features, at a time when most diabetes seen before late middle age was autoimmune (that is, type 1, or juvenile-onset diabetes as it was then known). Most people with MODY were not particularly obese, suggesting that the predominant defect in this condition was likely to be beta-cell dysfunction rather than insulin resistance. Detailed clinical studies of MODY families pointed to significant heterogeneity between families with regard to disease progression and severity (Fajans, 1990 Tattersall andMansell, 1991). With the advent of modern positional cloning techniques, the availability of multigenerational families and the promise of penetrant disease alleles meant that MODY became an attractive target for gene...

NCEPDefined Metabolic Syndrome Diabetes and Prevalence of Coronary Heart Disease Among Nhanes Iii Participants Age 50

May 2003. Contact Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website Summary Although the individual components of the metabolic syndrome are clearly associated with increased risk for coronary heart disease (CHD), the authors of this study wanted to quantify the increased prevalence of CHD among people with metabolic syndrome. The authors used the Third National Health and Nutrition Examination Survey (NHANES III) to categorize adults over 50 years of age by presence of metabolic syndrome, with or without diabetes. Metabolic syndrome is very common, with approximately 44 percent of the united States population over 50 years of age meeting the criteria. in contrast, diabetes without metabolic syndrome is uncommon (13 percent of those with diabetes). Older Americans over 50 years of age without metabolic syndrome, regardless of diabetes status, had the lowest CHD...

Type 2 diabetes the next global epidemic Definitions

In contrast to type 1 diabetes, which is known to result from autoimmune destruction of the insulin-secreting beta-cells of the pancreas, leading to lifelong dependence on exogenous insulin, the etiology of type 2 diabetes is poorly understood (Kahn, 2003). Whilst type 1 diabetes is typically diagnosed in childhood or early adulthood, type 2 diabetes classically presents in later life. These clinical distinctions lie behind previous disease classifications in which type 2 diabetes was known originally as maturity-onset diabetes, and subsequently, as non-insulin-dependent diabetes mellitus (World Health Organization Study Group, 1985). Under the most recent classification of diabetes subtypes, published in 1997 by a joint expert committee of the American Diabetes Association and the World Health Organization, individuals whose diabetes has an established basis - be that causal genetic variation (as in some monogenic forms of diabetes (see below)) or discrete environment risk factors...

Relationship between Diabetes Mellitus and Aging in the Development of Cardiovascular Diseases

Development of atherosclerosis, as it is also for type 2 diabetes. Aging per se could present a state of impaired glucose tolerance due to the physiologic changes described. IGT is known to be a risk factor for progression to type 2 diabetes. Aging associated with the occurrence of type 2 diabetes increases several-fold the risk for development of cardiovascular diseases by approximately six to eight times more than aging alone (Nesto, 2003). This is due mainly to the strong occurrence of the classical, including hypertension, dyslipidemia, and nonclassical, including inflammatory cytokines, homocystein, and CRP risk factors. Altogether, the common pathway could be the insulin resistance and insulinopenia-induced hyperglycemia via the production of AGEs and oxidative stress.

Insulin Receptor Signaling

Insulin and insulin-like growth factor-1 (IGF-1) signaling pathways have been implicated in aging of several experimental organisms (Pardee et al., 2004). This pathway is critical to coordinating the influx of calories with the metabolic rate. Down-regulation of this pathway through caloric restriction is associated with increased life span in mice, worms, flies, and yeast (Barbieri et al., 2003). One of the key transcription factors implicated in aging, namely, FOXO, is regulated by insulin and IGF-1. The FOXO homolog in worms, DAF-16, has a central role in imparting longevity of worms with mutations in the insulin IGF-1 signaling pathway genes, such as daf-2 and age-1 (Kenyon et al., 1993). Over-expression of dFOXO in worms and DAF-16 in flies extends life span through interactions with a host of other nuclear receptors, particularly the PPARs (Giannakou et al., 2004 Henderson and Johnson, 2003). These receptors are up-regulated during caloric restriction, and overexpression of PPAR...

Experimental Models Linking Diabetes Mellitus to Aging and Longevity

In some species, caloric restriction (CR) is associated with reduction of aging and increased longevity. It was observed that a reduced body size was correlated to an increased life span in mice, dogs, Caenorhabditis elegans, or Drosophila melanogaster. One very recent study could not find a clear general effect of body size on life span (Hafen, 2004 McCulloch et al., 2003). The question has been asked why smaller individuals would live longer. One explanation that has been put forward, mainly in invertebrates, is the homologous insulin IGF signaling (IIS). In C. elegans it was suggested that the IIS can act to limit the body size. However, in some wild-type strains this correlation was much less clear. Moreover, several mutations in C. elegans led to extended longevity phenotype. Among these are the genes involved in the insulin IGF-signaling pathway, such as daf-2 and age-1, or clk mutants related to respiratory metabolism. Similar results were obtained in Drosophila. The study in...

Pathogenesis of Diabetes Mellitus Type 2 in Relation to Aging

ALTERED INSULIN ACTION INSULIN RESISTANCE One factor clearly contributing to this age-related glucose intolerance is a decline with physiologic aging in sensitivity to the metabolic effects of insulin that is, the reduction of insulin sensitivity. This means a reduction in the activity of insulin on its target tissues such as muscle, liver, and adipose tissue. In the muscle this results in a decrease of glucose disposal. In the adipocytes this results in the inability of insulin to inhibit the lipolysis leading to the release of free fatty acids in the circulation. These FFAs in turn stimulate hepatic neoglucogenesis and VLDL secretion, reduce muscle glucose uptake, and may alter glucose-stimulated insulin secretion by beta cells. This age-related impairment of insulin action appears to be predominantly due to effects on the insulin signaling mechanism beyond the insulin receptor itself. However, the latter also may be involved to some extent (Fulop et al., 2003). In the liver the...

Agerelated Risk and Etiologic Factors for Diabetes Mellitus Type

Poor diet, genetic factors, obesity, and lack of exercise may partly explain the increased prevalence of glucose intolerance and type 2 diabetes with advancing age. Among the confounding factors for the development of type 2 diabetes associated with aging, the most important are increased body adiposity and reduced lean body mass. These changes are characteristic of the aging process, but individually can be found in many pathological states with similar untoward metabolic consequences. The concomitant occurrence of these body composition changes and aging per se probably has an important impact on the development of type 2 diabetes in elderly.

Insulinlike Growth Factor Axis Components

Mature IGF-I and IGF-II are single-chain polypeptides of 70 and 67 amino acids, respectively, with 62 overall sequence identity (4-5). Due to structural identity with insulin, the IGF polypeptide chain has been divided into four domains arranged as B-C-A-D. IGF A- and B-domains have 45 sequence identity with insulin A- and B-chain however, the connecting peptide C is shorter than the proinsulin C-chain, and the carboxyl-terminal D-domain extension is exclusive to IGF. Another parallel between IGF and insulin structure is the presence of three intrachain disulphide bonds arranged in the same disposition as in insulin, i.e., two connecting B- and A-domains and one intra-A-domain (6). Moreover, the IGF are synthesized as preproproteins with signal peptides of about 25 amino acids at the N-terminus of the B-domain, and further extensions of 35-85 residues at the C-terminus of the D-domain, termed the E-peptide (7). Although the signal peptide and E-domain are deleted sequentially by...

Noninsulindependent Type II diabetes mellitus

The incidence of non-insulin-dependent (i.e. Type II) diabetes mellitus (NIDDM) is increasing in adult urban populations around the world. The approximately 3 of adults currently affected by NIDDM will become an estimated 5 by 2025 (World Health Organization, 1998), as populations age and urbanize, and as obesity becomes more prevalent. NIDDM is a serious metabolic disorder which damages kidneys, heart, blood vessels and retina. The disorder results from ''insulin resistance'' - a reduction in the sensitivity of bodily tissues to insulin, the hormone which coordinates ''Thrifty genes'', and selective insulin resistance Almost a half-century ago, when obesity was much less prevalent than today, only a few populations (Pima Indians, Nauruans and other Polynesians, and Australian Aborigines) appeared to be particularly susceptible to diabetes. Further, the two main types of diabetes - adult-onset (NIDDM) and child-onset (insulin-dependent diabetes, IDDM distinguished by insufficient...

Heart Disease and Diabetes

January 2003. Contact Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website Summary This brief fact sheet reminds readers of the connection between heart disease and diabetes. The fact sheet notes that many conditions that increase one's changes of getting heart disease are more common in people with diabetes. These conditions include cholesterol problems, high blood pressure (hypertension), overweight, and blood clotting problems. Heart attacks, known in the medical community as myocardial infarctions, are one of the most common heart conditions. For most people, a heart condition leads to symptoms such as chest pain or pressure, jaw pain, arm pain, shortness of breath, sweating, and pounding heartbeat. However, many people with diabetes and heart disease do not notice any symptoms at all. This is called silent ischemia. Silent ischemia is very dangerous because...

Diabetes and Pregnancy

Pregnancies complicated with gestational diabetes have an increased risk of maternal and perinatal complications, long-term maternal morbidity, and morbidity to the offspring. The causes of perinatal morbidity are neonatal hypoglycemia, hyperbilirubinemia, hypocalcemia, polycythemia, macrosomia birth weight more than 9 lbs (or 4 kg), and with that the problem shoulder dystocia, an abnormal apgar score, and Erb's palsy. Family history of diabetes

Insulin And Gsk3

In 1960 Joseph Larner reported that the activity of glycogen synthase was increased within minutes when rat diaphragms were incubated with insulin 11 and, a few years later, he showed that this resulted from decreased phos-phorylation of this enzyme 12 . Following the discovery that PKA can phos-phorylate and inhibit GSK-3 in vitro 13,14 , it was thought that insulin must exert its effect on glycogen synthase by inhibiting PKA, but no decrease in the concentration of cyclic AMP could be detected in muscle under conditions where insulin stimulated glycogen synthase 12 . This led Joe Larner to suggest that insulin might trigger the formation of a second messenger or chemical mediator distinct from cyclic AMP, which bound to PKA and prevented its activation by cyclic AMP but, despite much effort, no such molecule was ever purified and characterised. However, when other glycogen synthase kinases were identifieid, I suggested that insulin might instead activate glycogen synthase by...

Diabetes Mellitus

Diabetes mellitus (DM) is an established risk for atherosclerosis and is associated with both microvascular and macrovascular disease. Accumulating evidence indicates that diabetes also is associated with increased risk of fracture of the hip, proximal humerus, and foot (Schwartz et al., 2003). Although the association of type 1 DM and low bone density is established, in type 2 DM there is a normal or high bone density despite evidence from epidemiologic data of increased fracture (Dominguez et al., 2004). This paradox is explained, in part, by altered bone structure leading to decreased bone strength. Furthermore diabetes is also associated with higher risk In patients with type 1 DM, mechanisms of increased bone loss are largely unknown. These patients also suffer from increased hip fracture at a younger age (Forsen et al., 1999). Poor metabolic control in adolescents with type 1 DM is associated with increased risk for osteoporosis in adult age (Valerio et al., 2002). Studies...

Type I Diabetes

The characteristic dysfunction is the destruction of pancreatic beta cells that produce insulin. This results clinically in hyperglycemia, ketoacidosis, and exogenous insulin dependence. Long-term clinical effects include neuropathy, retinopathy leading to blindness, and nephropathy leading to kidney failure. B. Type I diabetes demonstrates an association with the highly polymorphic human leukocyte antigen (HLA) class II genes that play a role in the immune response. The specific loci involved in Type I diabetes are called HLA-DR3 and HLA-DR4 loci they are located on the short arm (p arm) of chromosome 6 (p6). E. Markers for immune destruction of pancreatic beta cells include autoantibodies to glutamic acid decarboxylase (GAD65), insulin, and tyrosine phosphatases 1A 2 and

Ginseng And Diabetes

The value of ginseng preparations in the treatment of diabetes mellitus is debatable. Diabetes, diabetes mellitus or sugar diabetes, is a common condition occurring worldwide and amongst all classes of people but more frequently amongst the poor and the aged in modern industrialised communities. In such societies it is rated as the third most common cause of death after cancers and cardiovascular conditions. The disease is characterised by impaired carbohydrate metabolism caused by inadequate production in the pancreatic islets of Langerhans of the hormone insulin, a small protein molecule (molecular weight 5808) comprising two amino acid chains connected to each other by disulphide linkages. In the absence of insulin in the blood stream the blood sugar level rises abnormally (hyperglycaemia) and sugar passes readily into the urine with resultant glucosuria or polyuria. Such rapid liquid excretion leads in turn to the characteristic thirst of diabetics. Lack of insulin may also be due...


The antidiabetic potential of bitter melon is well established in normal, streptozocin-or alloxan-induced diabetic animals and in genetic models of diabetes (Ahmed et al 2004, Bailey etal 1985, Day et al 1990, Jayasooriya etal 2000, Karetal 2003, Miura et al 2001, 2004, Reyes et al 2005, Sarkar et al 1996, Shibb et al 1993). All parts of the plant (fruit pulp, seeds, leaves and whole plant) have shown activity. The hypoglycaemic activity is attributed to a mixture of steroidal saponins known as charantins, insulin-like peptides and alkaloids that are concentrated in the fruit (Grover & Yadav 2004). Based on studies with animal models, it appears that Momordica charantia increases the renewal of beta-cells in the pancreas, or may permit the recovery of partially destroyed beta-cells (Ahmed et al 1998), and stimulates pancreatic insulin secretion (Welihinda et al 1982). It also improves peripheral glucose uptake (Welihinda & Karunanayake 1986). A study with streptozocin-induced diabetic...

Preventing Diabetes

Nicotinamide has been proposed as a useful therapeutic agent for the prevention of type 1 diabetes and also as an adjunct to intensive insulin therapy (Pocoit et al 1996). Interestingly, nicotinamide has also been shown to cause insulin resistance resulting in increased insulin secretion in healthy subjects with a family history of type 1 diabetes (Greenbaum et al 1996). A concern therefore exists that monitoring such people for signs of development of the disease may be complicated by the use of nicotinamide. 2007 Elsevier Australia Protects beta-cells Type 1 diabetes is characterised by progressive beta-cell destruction, which leads to complete insulin deficiency at the time of diagnosis 80-90 of beta cells have been destroyed (Virtanen & Aro 1994). Nicotinamide has been shown to protect beta-cells from inflammatory insults and to improve residual beta-cell function in patients after onset of type 1 diabetes (Gale 1996, Lampeter et al One RCT using 25 mg kg versus 50 mg kg...

In one trial aloe juice consisting of 80 gel or placebo was given In a trial of 40 patients who were recently diagnosed with type 1 diabetes at the dose of 1 tablespoon twice dally. From day 14 the blood sugar levels In the aloe group began to fall significantly compared with the control group and Aloe vera 27 levels were also substantially reduced but cholesterol levels remained the same (Yongchalyudha et al 1996). A single blind, placebo-controlled trial found that oral aloe gel was more effective in reducing blood sugar levels when combined with glibenclamide than glibenclamide alone in 72 patients with type 2 diabetes. Patients took 5 mg of glibenclamide twice daily and 1 tablespoon aloe gel. Fasting blood glucose levels dropped appreciably after just 2 weeks' treatment, and...

Diabetes Assessment

Diabetes affects millions of people worldwide. It is a leading cause of death, and as a result, is a large area of study. Diabetes is actually a group of diseases characterized by aberrant glucose metabolism. Type I or insulin-dependent diabetes results from immune-mediated destruction of pancreatic beta-cells. Type II or noninsulin-dependent diabetes results in hyperglycemia without loss of endogenous insulin reserve or loss of pancreatic islets. Thus, Type II diabetes is characterized by the presence of insulin resistance, which is often associated with obesity and advancing age and accounts for most cases of diabetes. The use of mouse models and transgenic technology has been important in the understanding of this complex disease.42 Clinically, overt diabetic symptoms include polyuria, polydypsia, and weight loss. One easy pheno-typing assay is monitoring for glucose in the urine. This test should be performed weekly on at-risk mice. Many other phenotyping procedures and tests have...

Insulin Resistance

Insulin resistance is a common condition and can be seen, for example, in NIDDM, obesity, and hypertension. The inter-relationship between insulin resistance and these conditions, as well as the exact mechanisms for insulin resistance, have not yet been fully clarified. It has recently been clear that GH-deficient adults are also insulin resistant in peripheral tissues (as measured using the hyperinsulinemic euglycemic clamp technique 67,68 ). In our study, glucose disposal rate (GDR) in the GH-deficient group was less than half that of controls, when calculated according to body weight and when corrected for body fat (67). The decreased lean body mass and the increased abdominal obesity in GH deficiency may be of importance for this finding as the association between increased body fat mass and insulin resistance is stronger in the presence of abdominal obesity (69). Low levels of serum IGF-1 may also contribute to insulin resistance (70) as IGF-1 stimulates the glucose transport in...

Genetic Basis Of Hormonal Carcinogenesis

And some of these are eventually relevant to the constellation of such mutations needed to produce the malignant phenotype. Ovarian steroid hormones drive the process of cell division directly and are, thus, the primary carcinogens. The amount of ovarian steroid hormones produced during each menstrual cycle is under strong genetic control, and the relevant genes are those in the relevant sex steroid biosynthesis and metabolism pathway (Table 1.1). We assume that there are common ( 1 ) sequence variations in these genes, which can produce meaningful differences in total ovarian steriod exposure over a woman's lifetime. Of course, the same, or novel, sequence variants in these genes can be associated with the progression of hormone-related cancers, as has been well documented for variants in the androgen receptor gene.20 The details of the endocrine pathways and the relevant candidate genes will be discussed by several of the chapters in this book, so further details are not provided...

TABLE 5 Extraglandular Manifestations in Primary SS

Diagnosis of SS also requires exclusion of other conditions that can mimic it. These include previous radiation therapy to the head and neck, amyloidosis, sarcoidosis, lymphoma, graft versus host disease, hepatitis C virus infection, HIV-diffuse infiltrative lymphocytosis syndrome, medication-induced dryness, and uncontrolled diabetes mellitus.

Abnormal Involuntary Movement Scale

Tardive dyskinesia is a syndrome characterized by abnormal involuntary movements of the patient's face, mouth, trunk, or limbs, which affects 20 -30 of patients who have been treated for months or years with neuroleptic medications. Patients who are older, are heavy smokers, or have diabetes mellitus are at higher risk of developing TD. The movements of the patient's limbs and trunk are sometimes called choreathetoid, which means a dance-like movement that repeats itself and has no rhythm. The AIMS test is used not only to detect tardive dyskinesia but also to follow the severity of a patient's TD over time. It is a valuable tool for clinicians who are monitoring the effects of long-term treatment with neuroleptic medications and also for researchers studying the effects of these drugs. The AIMS test is given every three to six months to monitor the patient for the development of TD. For most patients, TD develops three months after the initiation of neuroleptic therapy in elderly...

Overview Of Racialethic Minority Health

Despite the fact that whites are the older group among the American population, blacks exhibit a 32 higher age-adjusted all-cause mortality rate, when compared to whites. American Indians or Alaska Natives, latinos and Asians or Pacific Islanders exhibit lower age-adjusted all-cause mortality rates by at least 28 than whites (Freid, et al., 2003). A similar scenario can be observed for selected causes of deaths such as heart disease, cancer and diabetes (Table 1). Blacks exhibit 28 and 26 higher age-adjusted mortality rates for disease of the heart and cancer,

Neuroprotection By Pparg Activation Against Ab Toxicity

PPARy participates in differentiation, insulin sensitivity, type 2 diabetes, arteriosclerosis, and cancer 67,68 . In particular, PPARy is a critical regulator of adipocyte differentiation 67 , a process also dependent on the Wnt signaling pathway 69 . Recent studies suggest that treatment of insulin resistance with a PPARy agonist retards the development of AD 73 , and recent studies have shown that some anti-inflammatory drugs that are PPARy agonists have neuroprotective actions in different animal models of neurodegeneration 74,75 . Accordingly anti-diabetic thiazolidinedione drugs have been shown to have a potent insulin-sensitizing action 76 that might be mediated through PPARy-mediated inhibition of GSK-3p 77 .

Biomedical Importance

Water is the predominant chemical component of living organisms. Its unique physical properties, which include the ability to solvate a wide range of organic and inorganic molecules, derive from water's dipolar structure and exceptional capacity for forming hydrogen bonds. The manner in which water interacts with a sol-vated biomolecule influences the structure of each. An excellent nucleophile, water is a reactant or product in many metabolic reactions. Water has a slight propensity to dissociate into hydroxide ions and protons. The acidity of aqueous solutions is generally reported using the logarithmic pH scale. Bicarbonate and other buffers normally maintain the pH of extracellular fluid between 7.35 and 7.45. Suspected disturbances of acid-base balance are verified by measuring the pH of arterial blood and the CO2 content of venous blood. Causes of acidosis (blood pH 7.35) include diabetic ketosis and lactic acidosis. Alkalosis (pH 7.45) may, for example, follow vomiting of...

Role Of Gsk3 In Neuronal Morphogenesis

Figure 3.2 Some pathways that modulate the kinase activity of GSK-3. These pathways may be classified in two main groups. First are the pathways that act through the inhibition of GSK-3 by increasing Ser9 21 phosphorylatio, such as those triggered by Insulin IGF-1 (IGF1) or by some growth factors (GFs) or by estrogen (E2). However, so far it is still not clear how GSK-3 is inhibited by the action of Wnt in these Wnt pathways. Second are the class of pathways in which GSK-3 is activated by LPA or Reelin. In these systems the precise molecular mechanism of how GSK-3 is activated still has to be defined. See color plates. Figure 3.2 Some pathways that modulate the kinase activity of GSK-3. These pathways may be classified in two main groups. First are the pathways that act through the inhibition of GSK-3 by increasing Ser9 21 phosphorylatio, such as those triggered by Insulin IGF-1 (IGF1) or by some growth factors (GFs) or by estrogen (E2). However, so far it is still not clear how GSK-3...

Chronological Aging And Response To Stress

Downstream effectors impacting longevity are also conserved. As is the case for yeast chronological life span, Daf-16-dependent up-regulation of superoxide dismutase accounts for a portion of the life span extension seen in long-lived insulin IGF-1 pathway mutants in C. elegans (Honda and Honda, 1999), and activation of the heat shock responsive transcription factor Hsf1 increases both chronological life span in yeast (Harris et al., 2001) and adult life span in the nematode (Morley and Morimoto, 2004). Further studies will likely uncover additional shared longevity determinants, and it will be particularly interesting to see how highly conserved the aging process is for nondividing cells in evolutionarily divergent eukaryotes.

Lipid Receptors Peroxisome Proliferator Activated Receptors

While PPARa contributes to systemic fatty acid disposal through oxidation, PPARy regulates and promotes lipid storage by its activities in adipocytes and macrophages. The y isoform was initially thought to be an adipose-specific NR, whose activation by the prostaglandin metabolite 15-deoxy-A12,14-prostaglandin J2 (or synthetic thiazolidinedione) resulted in differentiation of multiple cell types to an adipocyte phenotype.390-395 The adipogenic process minimally requires insulin and glucocorticoid signaling, as well as the activities of multiple basic helix-loop-helix-leucine zipper transcription factors of the CAAT enhancer binding protein and sterol regulatory element binding protein class.396 In addition to its established role in adi-pogenesis, however, PPARy performs unique roles in macrophage function, intestinal mucosal proliferation differentiation, and placentogene-sis.239,397-399 Activation of PPARy in these tissues may not induce the same program of target genes observed in...

Platelet FcyRIIa Numbers

Variable expression of FcyRIIa numbers among individuals could affect susceptibility to immune complex diseases (Rosenfeld et al., 1987) or even to HIT. The number of platelet surface-expressed FcyRIIa molecules is increased dramatically in HIT (Chong et al., 1993b). However, increased FcyRIIa expression is also seen after in vitro activation of platelets by HIT antibodies. Elevated FcyRIIa numbers may be a consequence of platelet activation in HIT, rather than a proximate cause. This notion is supported by the fact that increased platelet FcyRIIa levels are seen in patients with atherothrombosis and diabetes mellitus (Calverley et al., 2002).

Chemopreventative Effects

Chemopreventative actions demonstrated by n-3 EFAs include suppression of neoplastic transformation, cell growth inhibition and enhanced apoptosis, and anti-angiogenicity (Rose & Connolly 1999). The proposed mechanisms for these are extensive, including the suppression of n-6 eicosanoid synthesis influences on transcription factor activity, gene expression, and signal transduction pathways effects on oestrogen metabolism increased or decreased production of free radicals and reactive oxygen species, and influences on both insulin sensitivity and membrane fluidity (Larsson et al 2004). Ongoing research is attempting to elucidate the specific chemopreventative mechanisms of fish oils with the individual cancer cell lines.

Weight Gain Prevention Trials

To date, there have only been a modest number of structured and evaluated interventions, which have had a primary objective of preventing or limiting weight gain. However, a broader range of projects have examined the most effective strategies for improving physical activity or encouraging specific dietary change or for combating allied chronic noncommunicable diseases such as CHD, hypertension, and diabetes. Examining the lessons

Short Chain Fatty Acids

Short chain fatty acids are not an important dietary nutrient, however, they are being discussed at this point because they are a significant end product of carbohydrate and amino acid bacterial metabolism. Short chain fatty acids are readily absorbed from the human colon, and facilitate the absorption of salt and water by the colon. Colonic epithelium derives 60-70 of its energy from short chain fatty acids with butyrate being the most important in this regard (24). Short chain fatty acids also stimulate mucosal growth in the colon. As stated previously, the major short chain fatty acids produced by intestinal bacterial fermentation are acetate, butyrate, and propionate. Additional end acid products include lactate, succinate, and formate (25). The fate of these bacterially produced acid end products has been studied to varying extents. In humans, acetate is always found at a concentration of 50 micromolar in fasting venous blood. After a carbohydrate rich meal, these blood levels...

Mechanisms for MHC associations

An alternative view is that the association with a particular MHC molecule is indirect and reflects tolerisation of the T cell repertoire to self antigens. In other words, self peptides may drive the positive or negative selection of different clones of developing thymocytes. In many diseases a particular target cell type has been identified and in some the actual protein, or autoantigen, within that cell is known. In T1D, for example, the autoimmune T cell response is directed at pancreatic b cells that make insulin hormone. Insulin is an autoantigen but several other proteins in these cells are also targeted.

Functional Development of the ENS

Serotonin (5-HT) together with glucagon, insulin, peptide XY, gastrin, and somatostatin are the earliest neurohumoral substances to be expressed at about 8 weeks of gestation. By 24 weeks of gestation, most of the known gastrointestinal neurohumoral substances can be identified.

The Endothelium In Hemostasis

(Talusan et al., 2005) and an increase in expression of various cell adhesion molecules (for review see Fuster et al., 1998). The binding of advanced glycation end products to specific EC receptors during normal aging and diabetes mellitus increases vascular permeability, exposing the subendothelial matrix to lipoproteins and other injurious substances (Basta et al., 2004). It is also likely that genetic variation in EC behavior contributes to the host response to antibody- and platelet-mediated EC injury, although the methods to identify or monitor such risk factors remain to be developed. Thus, any inquiry into the reason why only a subset of patients who develop anti-PF4-heparin antibodies develop thrombosis, or why thrombi occur at restricted vascular sites, must take into consideration the specific attributes of the affected endothelial vascular bed.

Lean subjectObese subject

Concentration is a primary modulator of hepatic insulin resistance (115). This is consistent with the knowledge that in men and women omental and mesenteric adipocytes are metabolically more active by comparison to abdominal subcutaneous adipocytes. Thus sustained differences in portal concentration of free fatty acids may at least partially explain the hepatic and peripheral insulin resistance that characterize viscerally obese older persons. Although it is not possible to readily access the portal circulation in vivo, it is reasonable to expect that sustained delivery of free fatty acids to the liver would cause an increase in the infiltration of lipid within the liver hepatic steatosis or ''fatty liver.'' Consistent with this position, evidence suggests that visceral fat is a positive correlate of liver fat in men (112), but not women (116). Foster et al. (117) were among the first to illustrate the applicability of MRI to body composition analysis. Hayes et al. (118) first...

Nuclear Transfer To Generate Stem Cells

Most work on hES cells has taken place with a relatively small number of cell lines obtained from excess blastocysts donated from in vitro fertilization (IVF) programs. The genetic makeup of the cells is not controlled in any way, and genetic variation among lines needs to be considered when results from different lines are compared. Experience from research with mES cells shows that ES cell lines can differ markedly in their differentiation efficiencies. Being able to control the genotype of ES cells would be valuable for various reasons, most notably the desire to generate ES cells with genotypes known to predispose to particular diseases. In the case of single-gene defects, one could achieve that goal by deriving hES cells from discarded morulae or blastocysts that were identified with preimplantation genetic diagnosis (PGD) procedures (Verlinsky et al, 2005) as carrying mutations or by generating the appropriate mutation by gene targeting of established hES cell lines. However,...

PI3Kinase PKBAkt mTOR and Internal Signaling Pathways

ABSTRACT Best known for its normal physiologic function in insulin-mediated signaling and glycolysis, PI3-kinase and its effectors PKB Akt and mTOR are of particular interest to the oncologist due to their roles in tumorigenesis and response to therapy. Dysregulation of PI3-kinase signaling is implicated in mediating many features of malignancy, including aberrant growth, invasiveness, angiogenesis, and cell survival. The effective incidence of PI3-kinase dysregulation in malignant gliomas may be as high as 80 per cent, when one considers the number of aberrant signaling pathways converging through PI3-kinase and PKB Akt. In addition to contributing to gliomagenesis, constitutively activated PKB Akt is implicated in the development of resistance to both chemotherapy and radiotherapy. Although the mechanisms by which PI3-kinase, PKB Akt, and mTOR modulate responses to therapy are unclear, the signaling pathway outlined by these effectors may prove relevant in current and developing...

PI3kinase Function and Regulation

Phosphatidylinositol-3' kinase (PI3-kinase) is best known for its integral function in a number of physiologic processes, including insulin and growth factor receptor signaling, cell proliferation, and motility. Many lines of evidence demonstrate that PI3-kinase roles in proliferation and motility contribute to oncogenesis and tumor resistance to therapy. PI3-kinase is a lipid kinase composed of a p85 regulatory subunit and a p110 catalytic subunit. Upon activation, typically from membrane-based inputs such as growth factor receptors, the catalytic subunit phosphorylates phosphoinositides at the 3' position of the inositol ring to generate PI(3,4)P2 and PI(3,4,5)P3. These phosphorylated lipid products recruit PKB Akt to the membrane and activate it, resulting in the phosphorylation of PKB at its Ser473 and Thr308 residues 1 . As a major intracellular signaling effector, PI3-kinase transduces membrane-based activation from several sources, including G proteins such as Ras and receptor...

Reported Therapeutic Effects of Spices

Is a wonder medicine and has been used and researched for its many healing properties. Curcumin and curcumene in turmeric are the active compounds. Turmeric has protection against free radical damage and cancer prevention possesses anti-inflammatory properties by lowering histamine levels protects the liver against toxic compounds reduces platelets from clumping together thereby improving circulation and protecting against arteriosclerosis prevents cancer acts as an antipeptic ulcer and antidyspepsia agent and heals wounds. Researchers at UCLA (University of California at Los Angeles) have shown curcumin to slow the formation of, and even destroy, accumulated plaque deposits that play a key role in development of Alzheimer's disease. Allicin in garlic lowers cholesterol, capsaicin in chile peppers prevents blood clotting, trigonelline in fenugreek seeds prevents rise in blood sugar, and gingerol in ginger aids digestion. Research is being conducted on many more spices.

Discovery Of The Benzolactam Secretagogues

Even though excellent clinical efficacy with GHRP-6 had been demonstrated, L-692,429 was tested intravenously in humans in order to validate our peptidomimetic approach to GH release in humans. In healthy young males L692,429 (t1 2 3.8 h) was found to release GH in a dose-dependent fashion with a minimum effective dose of 0.2 mg kg (32). As observed with all the GHRPs, there were small transient increases in cortisol and prolactin after L-692,429 administration. No significant changes in other pituitary hormones or changes in insulin-like growth factor (IGF)-1, glucose, or insulin levels were observed. L-692,429 was well tolerated with only a transient flushing or warm sensation being reported. In healthy elderly (71 5 yr) subjects L-692,429 has been reported to release GH, although the response is somewhat less than in healthy young men (33). L-692,429 has also been shown to partially reverse glucocorticoid suppression of GH secretion and may therefore be useful in reversing the...

A327 Reversedphase chromatography

Insulin-like growth factor-I was separated from desGly1-Pro,2 the Met59 oxidation form, a misfolded form, and carbamylated material using a 25 x 6 cm Prochrom column operated at 50 C. Loading was 3g L. The chemotactic peptides N-formylated Met-Phe and N-formylated Met-Trp were separated on a C18 reversed phase support.35 Loading was greatest from a metastable state at a concentration capable of forming aggregates but prior to the appearance of visible colloids. Non-linear isotherms derived from single-component injection successfully predicted separations of the two peptides. Retention time was less accurately predicted, perhaps due to inaccuracies in calculating gradient formation, dwell time, or isotherm interaction.

B RTK Receptor Family

Ligand binding to RTK family receptors lead to dimerization of monomeric receptors or conformational changes in heterotetrameric receptors resulting in auto-phosphorylation of specific tyrosines in the cytoplasmic domain (Fig. 18). Tyro-sine autophosphorylation stimulates the intrinsic receptor tyrosine kinase activity and or generates recruitment sites for downstream signaling proteins containing phosphotyrosine-recognition domains such as the Src homology 2 (SH2) or the phospho-tyrosine-binding (PTB) domain 84 . Efficient phosphorylation of the substrates by RTK also requires association of the substrate to the activated RTK. The PTB domain of insulin receptor substrate 1 (IRS1) binds at pTYR972 of activated IR, and the pleckstrin homology domain targets IRS-1 to Figure 18 Schematic illustration of signaling cascades for the cellular responses to insulin-insulin receptor (IR) interactions. Insulin binding to its receptor activates tyrosine kinase activity resulting in...

Enhancement of Androgen Receptor Function by Nonsteroidal Activators

The recognition that the AR could be activated in a ligand-independent manner was somewhat surprising. Human AR is similar to progesterone and glucocorticoid receptors, which do not exhibit ligand-independent activation. In contrast, they are activated by ligands and nonsteroidal compounds in a synergistic manner. This cross-talk between peptide hormones and the AR is still not completely understood however, in some cases intermediate protein kinase pathways involved in ligand-independent activation of the AR have been identified. AR activation by peptide growth factors, such as insulin-like growth factor or epidermal growth factor, is most probably relevant to regulation ofcellular events in advanced PCA (25). These growth factors stimulate AR activity in the absence of ligand or synergistically in combination with low androgen doses. In patients who receive endocrine therapy for PCA, activation of the AR by low androgen doses is thus enhanced by peptide growth factors. Erb B2, which...

And Intravenous Anesthetics

With the aging population and an increase in health problems such as obesity, diabetes, and coronary artery diseases, perioperative management and anesthetic technique and medications that promote cardiovascular stability continue to offer challenges and new developments in the field of anesthesiol-ogy. These include new anesthesia medications, medical equipment and surgical technology, and anesthetic and surgical techniques. With further understanding of inhalational and intravenous anesthetics, maintaining stable, physiological cardiovascular function may be possible.

Recruitment for casecontrol studies

Recruiting controls raises the same legal questions regarding data protection as does recruiting cases, and some additional problems too. A convenient method to recruit controls is the use of a sample cohort established for researching a different disease. For example, if the project intends to research breast cancer, controls could be recruited from a previously performed study on diabetes, where samples and data were kept for further use. If, however, these data are not completely anonymised, the problem of the secondary use of samples is raised, since the research exemption in the Data Protection Act 1998 does not cover secondary use. Thus, using data for a purpose different from the one the data was initially collected for requires additional consent from the data subject (Lowrance, 2002). Obtaining informed consent from data subjects, perhaps several years after the samples and information were taken, may prove difficult. Guidance from professional health authorities and related...

Ivwhy The Focus On Environments

Obesity, like diabetes and coronary heart disease, has higher prevalence rates among the lower-socioeconomic status (SES) populations in developed countries. Low income and low educational attainment bring reduced options for low-SES groups and a lower uptake of health messages about behavioral changes for a healthy future. One of the key strengths of an environmental focus is its potential impact among lower-SES groups. By influencing the ''default'' choices in key environments, there is a much greater potential to affect overall diet and physical activity patterns in lower-SES groups than by education strategies alone. Education-based campaigns are complementary to the environmental approach, but the priority needs to be on ensuring that the healthy choices are available first, before embarking upon such campaigns to educate people about taking up those choices.

Evidence For Tcell Mediated Autoimmunity In Ms

Wulff et al. (88) took another approach to explore the previous exposure of T-cells to myelin antigens as indirect evidence for autoimmune pathogenesis of MS. They exploited their finding that human effector memory T-cells express high levels of the voltage-gated Kvl.3 channel, whereas naive and central memory T-cells express far lower levels. T-cells reactive with MOG, MBP, or PLP from MS patients expressed far more Kvl.3 channels per cell than T-cells reactive with these antigens from control subjects. In contrast, the level of Kvl.3 channels in GAD65-reactive T-cells, insulin-reactive T-cells, and the vast majority of ovalbumin-reactive T-cells derived from MS patients was low and not higher than that for controls. Mitogen-reactive T-cells from MS patients and controls had similar levels of Kvl.3 channels per cell, suggesting that the general level of effector memory T-cells in MS patients was similar to that of the controls. Taken together, data from the studies discussed in the...

Magnetic Resonance Imaging

In practice, MRI should be reserved for patients with lesions that cannot be diagnosed on CT with confidence. In particular, patients with very fatty livers either from obesity, diabetes, or chemotherapy-related liver damage would particularly benefit from MRI evaluation. MRI should also be used if CT and US cannot delineate with certainty the proximity of cancerous deposits to major vasculature.

Clinical Aspects

Insulin Diabetes mellitus, or more usually diabetes, is the most common disease associated with the pancreatic islets it may affect 1-5 of the total population. In the United States it is estimated that more than 12 million people have some form of diabetes annually some 200,000 individuals are newly diagnosed as diabetic. Diabetes is the eighth leading health-related cause of death in the United States. More than 50 of diabetics die because of coronary disease individuals with juvenile-onset diabetes usually succumb because of renal failure. Diabetes is the second highest causative factor of blindness. The term diabetes means running through characteristic features are polydipsia and polyuria. Mellitus is Latin for honey (i.e., sweet). In a classic sense, diabetes mellitus is not a single disease because it has no single definable and distinct etiology. The major pathophysiological abnormalities generated by diabetes mellitus include the following (i) glucose intolerance or...

Analysis Of Nonenzymatically Modified Proteins

This section discusses two families of structural proteins, namely, extracellular keratins and collagens. Each example represents a family of closely related chemical entities, which means dealing with complex protein mixtures. We consider two types of chemical modifications modifications arising from increased levels of glucose in body fluids (obviously related to diabetes) and those derived from acetaldehyde, the first metabolic product of ethanol ingestion. As noted, a common feature of the latter nonenzymatic modification reactions is the presence of an aldehydic functionality in the nonprotein reac-tant ( Jelinkov et al., 1995 Deyl and MikSik, 1995).

Guidelines for the patient

The proper injection of insulin is very important to allow your body, which lacks natural insulin, to function as normally as possible. You should be very strict about the way you manage your insulin injections and have your technique down to a fine art. Common mistakes poor mixing technique when mixing insulin not taking insulin when you feel ill Drawing up the insulin Make sure your technique is checked by an expert. You may be using either a single insulin or a mixed insulin. A mixed insulin is a combination of shorter and longer acting insulin and is cloudy. Always draw up clear insulin first. Do not permit any of the cloudy insulin to get into the clear insulin bottle. Do not push any of the clear insulin into the cloudy insulin bottle. Take your insulin every day, even if you feel ill.

Adverse effects may cause hypertension, dysrhythmias, headache, nervousness, nausea vomiting, myocardial ischemia dysrhythmias potentiated by halothane metabolic effects increases adipose tissue lipolysis, liver glycogenolysis, inhibits release of insulin.

The importance of diet

All diabetics require a diet in which refined carbohydrate and fat intake is controlled. The objectives of the diet are to keep the blood sugar level as near normal as possible spacing the meals throughout the day (three main meals and three snacks) for many type I diabetics

Psychosocial considerations

The psychological and social factors involving the patient are very influential on outcome. Considerable support and counselling is necessary to help both patient and family cope with the 'distress' of the diagnosis and the discipline required for optimal control of their blood glucose. Reasons for poor dietary compliance and insulin administration must be determined and mobilisation of a supportive multidisciplinary network (where practical) is most helpful. The general practitioner should be the pivot of the team. Joining a self-support group can be very helpful.

Concluding Remarks

As discussed extensively in other chapters of this book, there exists major pharmaceutical interest in the development of novel, potent inhibitors of GSK-3, and many companies have a GSK-3 inhibitor development program (see 20,60,145-147 for more detailed discussions). The majority of current efforts have resulted in small molecule inhibitors that act by inhibiting the interaction of GSK-3 with ATP. Many of these inhibitors have had some effects on other kinases, most commonly cyclin-dependent kinases (CDKs). Thus much current effort is being placed on designing testing drugs with greater specificity 148 . One approach has been to develop inhibitors that are non-ATP competitive 149 . For example, Eldar-Finkelman and colleagues have reported the development of L803-mts, a substrate competitive inhibitor that is active in rodent models of both diabetes and depression 136,150 . Competition for substrate, and through other non-ATP competitive approaches, has the potential to inhibit GSK-3...

Adverse Reactions

In a placebo-controlled, double-blinded, randomised clinical trial of 39 patients, glucosamine supplementation was found to have no clinically significant effect on glycaemic control in patients with type 2 diabetes over 12 weeks, and another 12-week randomised double-blind study found that glucosamine sulfate supplementation did not cause glucose intolerance, with no alterations in serum insulin or plasma glucose levels in 19 healthy subjects (Tannis et al 2004).

Broad etiological groups

Alcohol (May and Gossage, 2001) and maternal diabetes (Schwartz and Teramo, 2000) as teratogenic influences are considerable. Hampering attempts to quantify the effects of these agents is the observation that a given teratogen can have pleiotropic developmental effects and conversely many contributors, both environmental and genetic, can produce similar patterns of anomalous development. Adding to this complexity is emerging evidence to support the role of genetic factors in influencing the metabolism of, or degree of exposure to, human teratogens such as the anti-convulsant sodium valproate (Duncan et al., 2001) and ethanol (Stoler et al., 2002 Chambers and Jones, 2002).

The Liver Plays A Central Role In Lipid Transport Metabolism

The cellular events involved in VLDL formation and secretion have been described above. Hepatic triacyl-glycerol synthesis provides the immediate stimulus for the formation and secretion of VLDL. The fatty acids used are derived from two possible sources (1) synthesis within the liver from acetyl-CoA derived mainly from carbohydrate (perhaps not so important in humans) and (2) uptake of free fatty acids from the circulation. The first source is predominant in the well-fed condition, when fatty acid synthesis is high and the level of circulating free fatty acids is low. As triacylglyc-erol does not normally accumulate in the liver under this condition, it must be inferred that it is transported from the liver in VLDL as rapidly as it is synthesized and that the synthesis of apo B-100 is not rate-limiting. Free fatty acids from the circulation are the main source during starvation, the feeding of high-fat diets, or in diabetes mellitus, when hepatic lipogenesis is inhibited. Factors...

Clinical Considerations

Type 1 diabetes is marked by autoantibodies and an insulitis reaction that results in the destruction of pancreatic beta cells. b. It is characterized clinically by hyperglycemia, ketoacidosis, and exogenous insulin dependence. Long-term clinical effects include neuropathy, retinopathy leading to blindness, and nephropathy leading to kidney failure. C. Type 1 diabetes is a multifactorial inherited disease, which means that many genes that have a small, equal, and additive effect (genetic component) and an environmental component are involved. If one considers only the genetic component of a multifactorial disease, the term polygenic is used. 2. Genetic studies of type 1 diabetes show an association with human leukocyte antigen (HLA) complex loci named HLA-DR3 and HLA-DR4 located on the p arm of chromosome 6 (6p). b. Glutamic acid decarboxylase (GAD65), insulin, and tyrosine phosphatases 1A-2 and IA-2 autoantibodies are found. B. Type 2 diabetes...

Histamine2receptor blockers H2Bs

This class of medications indirectly suppresses gastric acid and pepsin secretion by occupying Histamine2 receptors. They suppress basal, nocturnal, and penta-gastrin secretion, as well as acid secretion induced by insulin, meals, and sham feeding 74 . These medications have no effect on LES pressure or esophageal clearance 31 . Acid suppression is incomplete in response to meals, thus these are less effective in people with advanced reflux disease 35 . The H2B's reduce nocturnal acid by 85-94 if appropriate doses are determined 74 . Clinical trials have shown that, compared to placebo, H2B's improve the endoscopic appearance of the esophagus and reflux symptoms in the majority of patients after 6-8 weeks of treatment 27 , 73 . In a general population, symptomatic relief can be expected in 32-82 of patients (mean 60 ) after a 12 week course, with resolution of en-doscopically confirmed esophagitis in 0-82 (mean 48 ) 13 , 34 , 35 , 50 , 71 , 73 , 74 .

The intrauterine diabetic environment an intrauterine teratogenic milieu

The exposure of the developing embryo and fetus to metabolic derangements associated with maternal diabetes mellitus (DM) is a well documented, commonly occuring, but still poorly understood, example of a teratogenic environmental influence (Martinez-Frias, 1994 Reece et al., 1996). A large number of structural malformations have been described in infants of diabetic mothers (Table 13.5). Despite an undisputed association of first trimester hyperglycaemia with the occurrence of malformations (Miller etal., 1981), the teratogenicity of gestational diabetes, a transient state of glucose intolerance induced by pregnancy, is in dispute (Kalter, 1998 Kousseff, 1999). Recent studies indicate that the risk of malformations in infants of mothers with mild gestational DM is significantly lower than maternal diabetes established prior to conception (Sheffield et al., 2002). Table 13.5. Structural malformations associated with maternal diabetes mellitus Some malformations are vastly...

Gluconeogenesis Control of the Blood Glucose


The changes in enzyme activity in the liver that occur under various metabolic conditions are listed in Table 19-1. The enzymes involved catalyze nonequilibrium (physiologically irreversible) reactions. The effects are generally reinforced because the activity of the enzymes catalyzing the changes in the opposite direction varies reciprocally (Figure 19-1). The enzymes involved in the utilization of glucose (ie, those of glycolysis and li-pogenesis) all become more active when there is a superfluity of glucose, and under these conditions the enzymes responsible for gluconeogenesis all have low activity. The secretion of insulin, in response to increased blood glucose, enhances the synthesis of the key Starvation and Diabetes Insulin Insulin Glucose 6-phosphate1 Insulin Insulin Insulin, fructose Fructose 1,6-bisphosphate1, insulin CoA, NAD+, insulin,2 ADP, pyruvate Insulin Insulin Insulin Insulin Insulin Insulin Insulin Insulin Insulin Citrate,1 insulin Insulin Both dehydrogenases of...

Complications And Prognosis

Invasive fungal sinusitis is devastating. Many patients will not survive, and those who do often are left with permanent disfigurement. The overall mortality ranges from 25 to 75 . The most important predictor of survival is successful correction of the predisposing condition. This includes control of ketoacidosis in diabetics and reversal of the underlying immunocompromised state. Risk factors associated with death include delayed diagnosis, presence of hemiparesis, bilateral sinus involvement, leukemia, renal disease, and treatment with deferoxamine.

Expression of the 65kDa Isoform of Human Glutamate Decarboxylase in P pastoris and P methanolica

Human glutamate decarboxylase (GAD65) is expressed exclusively in pancreatic islet (5 cells and is thought to be an important autoantigen in the development of type I diabetes (Baekkeskov et al., 1990). GAD65 was expressed as an intracellular protein in P. pastoris and P. methanolica (Raymond et al., 1998). For P. pastoris, the GAD65 cDNA (Karlsen et al., 1991) was inserted into pHIL-D2, several hundred His+ transformants were screened for GAD65 expression, and a high-expressing strain identified in a secondary expression screen was fermented (see Chapter 6). For P. methanolica, the GAD65 cDNA inserted into pCZR134 was used to transform PMAD16 cells to Ade+, and screening yielded an auglA strain, PGAD4-2, that harbored about eight copies of the GAD65 cDNA (Raymond et al., 1998). Strain PGAD4-2 was used to express GAD65 in a fermentor as described in the Appendix. Protein-normalized cell extracts were prepared from samples of GAD65 expressing P. pastoris and P. methanolica cells, and...

Body Fat Distribution

In a recent study in Singapore we found that the relative risk for having at least one cardiovascular risk factor (e.g., elevated cholesterol, hypertension, diabetes mellitus) is elevated at levels of WC or WHR far below the WHO cutoff points (50). Using WHO cutoff points for classification of abdominal obesity (30) would miss a large part of the population at risk. This elevated risk could be due to a higher amount of visceral fat at low WC or to other factors, e.g., genetic factors. Further studies in Singapore are needed to determine the relationship between anthro-pometric measurements (WC and WHR) and the amount of visceral fat by CT or MRI.

Fungal Infections in the Immunocompromised Host

For the most part, the Mucorales are considered to be opportunistic pathogens. They require a breakdown in the immune defenses, particularly disease processes that lead to neutropenia or neutrophil dysfunction. Although neutrophil dysfunction induced by ketoacidosis underlies the majority of cases of human zygomycosis, neutropenia induced by bone marrow suppression during chemotherapy or immunosuppression induced following transplantation is causing a growing proportion of cases. Specifically, the growing numbers of immunocompromised patients receiving organ transplants or cytotoxic therapies are changing the epidemiology of rhinocerebral mucormycosis (RCM). While diabetes mellitus accounts for 70 to 90 of RCM in earlier literature reviews, more recent studies have reported underlying diabetes in only 27 to 60 of patients with this disease (9). Currently, most patients with RCM have underlying hematologic disorders or are immunosuppressed recipients of organ transplants. The mechanism...

Non Cancer Health Care and Health Maintenance

The IOM report suggested in its title that many cancer survivors are lost in transition and that the quality of care suffers when patients and providers do not know what is expected after primary treatment ends. While much of the focus of research and guidelines has been on cancer surveillance, non-cancer health care is equally as, and in many cases more important than surveillance. Most patients diagnosed with cancer today are expected to survive it.28 Studies have shown that potentially preventable conditions like heart disease and diabetes are actually the greatest threat to life for many of these patients.83,84 As a result, despite the fact that a diagnosis of cancer tends to subjugate all other concerns for a while, preventive care and the management of other medical conditions may actually be more important in the long run. While studies have shown cancer survivors usually have more medical contacts than people without a history of cancer,86 there is also evidence that they may...

Mucormycosis in Children

In addition to cases involving immunosuppressed children, mucormycosis also has been observed in neonates (especially very-low-birth-weight premature infants weighing less than 1000 g), burn patients, and children with a history of incidental trauma. As with adult patients, the occurrence of mucormycosis depends on host immunity, but the mechanisms of increased susceptibility in certain hosts remain perplexing. In a pooled review by Kline of 41 cases of RCM in children aged 2 months to 18 years, 49 of cases were found in children with diabetes mellitus and 15 of cases were found in children with leukemia (10). In 10 of cases in these children, no predisposing conditions were present. In neonates, these invasive fungal infections have been observed to be rapidly fatal the time from clinical symptoms to death ranges from 6 to 42 days.

Enhancement Of Productivity

In terms of downstream processing efficiency, secretory expression systems indeed offer potential advantages for production of recombinant proteins compared with inclusion body-forming cytosolic systems, but most of the potentially available secretory systems are not yet fully competitive for high-volume therapeutics like insulin and therefore still require intensive improvement efforts. Completely different is the situation faced in the production of the so-called natural products, which are mostly secondary metabolites and therewith the endproducts of complex biosynthetic pathways of filamentous bacteria and fungi and thus require different approaches. With few exceptions like the antidiabetic drug acarbose (Glucobay) 5 or the chosterol-lowering drug lovastatin (Mevicor) 85 , such fermented pharmaceuticals of natural origin currently belong for the most part to the class of antibiotics 86 .

Calorie Restriction An Effective Intervention in the Rhesus Model

Calorie restriction (CR) has been long recognized for its benefits to health and aging in a variety of species (Weindruch and Walford, 1988). These benefits have been demonstrated in numerous studies of invertebrate and vertebrate models, which have shown that CR is a robust method for slowing aging as evidenced by reduced incidence and delayed onset of age-related diseases, extension of mean and maximum lifespan, increased stress resistance, and improved function (Bordone and Guarente, 2005). However, longitudinal CR studies are difficult in nonhuman primates due to their long lifespan and availability of sufficient numbers of animals to conduct this type of a study (Roth et al., 2004). Long-term studies have focused on obesity and diabetes (University of Maryland Medical School), and on the impact of a nutritious, low calorie diet (30 CR) on aging processes, survival, and longevity (Wisconsin National Primate Research Center and NIA). The NIA and WNPRC studies represent the first...

Barriers to Creating a Formal Survivorship Care Plan

Cancer survivors make more office visits for cancer care with PCPs than with oncologists.90 While this may often be due to insurer mandates or specialist availability, it is important to optimize the opportunity this presents. Oncologists often lack the time to adequately provide all care to all cancer patients and survivors. Moreover, there is not sufficient manpower to sustain an entirely specialist-based model of survivor care given the nation's growing population of cancer survivors. PCPs are better positioned and qualified to ensure that the full spectrum health needs of cancer survivors are addressed, including not only issues surrounding their cancer but also health maintenance (prevention), the management of concurrent comorbid disease (e.g., heart disease, diabetes), mental health,

Characterization of hESCDerived Hematopoietic Cells In Vivo

Fill a 3-mL syringe coupled to a 27-gage needle with 2 mL D-PBS. Rinse a 28-gage insulin syringe (0.5 in., 0.3 mL) with IMDM medium to fill the dead space, then carefully fill the barrel with the cell suspension. 11. Gently withdraw the 27-gage needle and keep the leg position unmoved. Insert a 28-gage insulin syringe into the channel made by the 27-gage needle. Inject 25 L of cell suspension. 3. Flush bone marrow into a FACS tube with an insulin syringe containing 1 mL of DMEM.

Complications Prognosis And Prevention

Preventive measures for patients other than the transplant and chemotherapy population require addressing the underlying risk factors for developing zygomycosis. Adequate control of diabetes, the use of iron chelators other than deferoxamine (such as substitution of hydroxypyridinone chelators for deferoxamine in patients who require such therapy), limitation of the use of aluminum-containing buffers in dialysis, and aggressive direct and culture-based detection of zygomycosis are among the best preventive measures. Keeping a high level of suspicion for zygomycosis in patients at risk can aid in early diagnosis and implementation of appropriate therapy.

The Discovery Of Gsk3

In late 1971 I had joined the Department of Biochemistry at the University of Dundee as a junior member of the Faculty after spending two years as a postdoctoral fellow studying the regulation of glycogen metabolism in Edmond's Fischer's laboratory at the University of Washington, Seattle. At that time only four enzymes were known that were regulated by phosphorylation, namely glycogen phosphorylase (activated by phosphorylase kinase) 1 , phosphorylase kinase 2 and glycogen synthase 3 (activated and inactivated, respectively, by cyclic AMP-dependent protein kinase, PKA), and pyruvate dehydrogenase (inactivated by pyruvate dehydrogenase kinase) 4 . No protein kinase had been purified to homogeneity or characterised in molecular terms, and so I decided to tackle phosphorylase kinase. This led me to discover that its regulation by PKA involved its phosphorylation at two serine residues, one on the a-subunit and one on the P-subunit of the enzyme. This was unexpected, because the...

Management Of Risk Factors In Overweightobese Persons

In patients who are overweight obese, clinical focus should be directed first to the risk factors associated with obesity. Most of these risk factors relate to cardiovascular disease, but some may indicate an increased susceptibility to type 2 diabetes. Management of the metabolic risk factors that are characteristic of the metabolic syndrome will be discussed. However, consideration will be given first to management of elevated low-density lipoprotein (LDL) cholesterol, which is the prime risk factor for development of atherosclerotic coronary heart disease.

Colorectal cancer epidemiology

Figure 17.1a demonstrates that colorectal cancer is more common in males than in females and in both sexes the incidence rate increases with advancing age. This difference in sex incidence may partly be explained by evidence from a number of case-control and cohort studies which demonstrated an association between hormone replacement therapy (HRT) and colorectal cancer, with the majority of these suggesting a protective effect (Giacosa et al., 1999). Accumulating evidence implicates obesity as a risk factor for colorectal cancer (Giacosa et al., 1999), and a positive association may exist between colorectal cancer and diabetes (La Vecchia et al., 1997). Not surprisingly, smoking has also been suggested as a significant risk factor (Giovannucci, 2001). Many studies have elucidated precise dietary and other variables responsible for the observed

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
