The Molecular Endocrinology Of Diabetes Mellitus

Diabetes mellitus is a metabolic syndrome characterized by hyperglycemia resulting from variable defects in insulin secretion and action. Traditionally, diabetes mellitus has been divided into four categories Type 1 diabetes, characterized by absolute insulin deficiency and requirement of insulin therapy to sustain life Type 2 diabetes, characterized by variable defects in insulin secretion and action, without an absolute need for insulin therapy (although insulin might be necessary for adequate control of hyperglycemia) other specific types of diabetes and gesta-tional diabetes. Type 1 diabetes is further subdivided into Type 1A, or autoimmune, diabetes and Type 1B, or idiopathic diabetes. The other category is very large, encompassing diabetes resulting from other illness or medications (such as cystic fibrosis-related diabetes) as well as many genetic syndromes that include diabetes (101).

Formulation of insulin products

Intermediate Acting Insulin Peak

Insulin, whatever its source, may be formulated in a number of ways, generally in order to alter its pharmacokinetic profile. Fast (short)-acting insulins are those preparations that yield an elevated blood insulin concentration relatively quickly after their administration (which is usually by s.c. or, less commonly, by i.m. injection). Slow-acting insulins, on the other hand, enter the circulation Table 11.3 Native and engineered human insulin preparations that have gained approval for general medical use. Reproduced in updated form with permission from Walsh, G. 2005. Therapeutic insulins and their large-scale manufacture.

Side Effects Contraindications and Safety of Metformin

Gastrointestinal side effects, including abdominal discomfort and diarrhoea, are the most common adverse events, occurring 10-15 of patients, depending on the dose 1,8,11 . These side effects usually improve with continued use and are minimal if started at a low dose (e.g. 250-500 mg d) and slowly titrated upward. Discontinuation of therapy because of side effects occurs in less than 4 of patients. Because metformin does not increase insulin secretion 3 , biochemically documented hypogly-caemia is rare 11 in diabetic patients treated with metformin alone (Table 1). Metformin is contraindi-cated in patients with risk factors for lactate acidosis or drug accumulation, for example in those with moderate to severe kidney, liver or cardiac dysfunction. Metformin is contraindicated in renal failure because of the associated risk for lactate acidosis. It can be used at low dosages up to a creatinine clearance of 30-60 mL min and should be avoided with clearances

Conventional Intensified Insulin Therapy or Multiple Daily Insulin Injections MDI

Nph Insulin Drawn First

In conventional intensified insulin therapy (MDI) using the basal-bolus approach with MDI, continuous basal insulin supply is obtained by once- or twice-daily subcutaneous injections of longer-acting preparations, supplemented by mealtime injections of more rapid-acting formulations. Rapid-Acting (Mealtime) Insulins These include structurally unchanged regular insulin preparations and short-acting insulin analogues (SIAs), which dissociate more rapidly than regular insulins and are absorbed faster. The glucose-lowering effect of rapid-acting insulins is enhanced by exercise within 1-3 h after the meal and by reducing the carbohydrate content of the meals. Regular (Soluble) Insulins Following subcutaneous injection of structurally unchanged regular insulin preparations, the native insulin tends to associate a hexameric form, which is slowly dissociated to single molecules and absorbed, thereby interfering with recreation of the physiological prandial insulin response (Table 1).

Production of human insulin by recombinant DNA technology

Human insulin produced by recombinant DNA technology was first approved for general medical use in 1982, initially in the USA, West Germany, the UK and The Netherlands. As such, it was the first product of recombinant DNA technology to be approved for therapeutic use in humans. From the 1990s on, several engineered insulin products (discussed later) also gained approval (Table 11.3). The initial approach to recombinant insulin production taken entailed inserting the nucleotide sequence coding for the insulin A- and B-chains into two different E. coli cells (both strain K12). These cells were then cultured separately in large-scale fermentation vessels, with subsequent chromatographic purification of the insulin chains produced.

Adverse Reactions to Insulin Therapy

The most common side effect associated with insulin therapy is hypoglycemia, which may result in such CNS symptoms as tremors, lethargy, hunger, confusion, motor and sensory deficits, seizures, and unconsciousness. Adrenergic manifestations include anxiety, palpitations, tachycardia, and diaphoresis. In many cases, diabetics are aware that hypoglycemia is developing, and prompt administration of oral carbohydrates (e.g., fruit juice or glucose tablets) can restore normoglycemia. In more severe cases (e.g., unconsciousness, seizures), intravenous glucose or intramuscular glucagon is required to reverse the hypoglycemia. Another frequent side effect of insulin therapy is weight gain. Some is due to increased caloric storage of glucose by insulin, and some is due to renal sodium retention resulting in fluid retention and edema. These effects can synergize with oral agents that are often coad-ministered with insulin, particularly sulfonylureas and thiazolidinediones.

Mechanisms of Action of Metformin

Energieumwandlung Achterbahn

The mechanism by which metformin exerts its antihyperglycaemic effects is still not entirely clear, but may be mediated by activation of hepatic and muscle adenosine monophosphate-activated protein kinase 2 , which is a major regulator of lipid and glucose metabolism. Metformin improves fasting and postprandial glucose levels during an oral glucose tolerance test, whereas the plasma insulin response to glucose is unchanged or may be decreased in patients with hyperinsulinemia 3 . Metformin ameliorates hyperglycaemia by reducing hepatic glucose production and gastrointestinal glucose absorption and improving peripheral sensitivity to insulin 4-7 . Unlike sulfonylureas, it does not stimulate insulin secretion, aggravate hyperinsu-linemia or cause hypoglycaemia 3-7 . However, the insulin-sensitizing effect of metformin is much smaller compared with that of thiazolidine-diones 7 .

Insulin

Insulin And Hypokalemia

Hyperglycemia is an obvious metabolic accompaniment of diabetic emergencies and therefore it is tempting to correct it to normal values rapidly. However, hyperglycemia itself is not life threatening, although the metabolic sequelae and fluid losses can be. The high blood glucose levels may have been reached over days and sometimes weeks. The body's osmolar and metabolic homeostasis has slowly adjusted to this new biochemical environment. When insulin is given, the glucose is encouraged to move into the cell, causing water, potassium, magnesium, phosphate, and other compounds to enter the cell also. If this occurs too rapidly, it can be dangerous, to give an initial insulin bolus. Fig. 1 Effects of insulin therapy insulin not only reduces the blood glucose levels, but also causes water and electrolytes to move into cells, with potential adverse effects. Insulin should be commenced as an intravenous infusion at a low level (1 unit h).

The insulin molecule

Insulin was first identified as an anti-diabetic factor in 1921, and was introduced clinically the following year. Its complete amino acid sequence was determined in 1951. Although mature insulin is a dimeric structure, it is synthesized as a single polypeptide precursor, i.e. preproinsulin. This 108 amino acid polypeptide contains a 23 amino acid signal sequence at its amino terminal end. This guides it through the endoplasmic reticulum membrane, where the signal sequence is removed by a specific peptidase. Proinsulin-containing vesicles bud off from the endoplasmic reticulum and fuse with the golgi apparatus. Subsequently, proinsulin-containing vesicles (clathrin-coated secretory vesicles), in turn, bud off from the golgi. As they move away from the golgi, they lose their clathrin coat, becoming non-coated secretory vesicles. These vesicles serve as a storage form of insulin in the P-cell.

Pathophysiology and Pathogenesis of GDM

Pathophysiology Gdm

Normal pregnancy and GDM are states of profound insulin resistance and the mediating factors are similar, if not identical. However, women who develop GDM tend also to be insulin-resistant when not pregnant and become even more insulin-resistant during pregnancy 18 . GDM develops when p cells are unable to compensate the increasing insulin resistance with sufficiently greater insulin secretion to maintain normal fasting and or postprandial glucose concentrations 18, 19 . For many years, clinical and research evidence has indicated a role for the placenta in the development of insulin resistance and the list of putative mediators of this effect is long (table 2). The placenta is also an endocrine organ and numerous studies have demonstrated potential mechanisms for hormones of placental origin to contribute to insulin resistance. Furthermore, insulin sensitivity is restored quickly after the placenta is expelled.

Secretion and Action of Incretin Hormones in Physiology

Guidance Medical Physiology Diabetes

The ingestion of nutrients elicits the secretion of gastrointestinal hormones intimately involved in the regulation of gut and gallbladder motility, digestive juice secretion, and postprandial carbohydrate metabolism. In particular, incretin hormones stimulate insulin secretion from the endocrine pancreas. Through the action of incretin hormones, enteral nutrition provides a more potent insulinotropic stimulus relative to an isoglycemic intravenous challenge. This phenomenon is named the incretin effect 3,21-23 . The first incretin to be identified, GIP, was purified from porcine intestine extracts by virtue of its ability to inhibit gastric acid secretion (therefore, the original name was gastric inhibitory polypeptide) 7,24 . Soon, it was discovered that GIP displayed potent insulinotropic actions in animals 8,25 and in human subjects 9 .

Alcohol Intake

The ADA recommend that if individuals choose to drink alcohol, daily intake should be limited to one drink for adult women and two drinks for adult men. It should be avoided by pregnant women and people with other medical problems, like pancreatitis, advanced neuropathy, severe hypertriglyceridemia or alcohol abuse. Since it can have both hypoglycemic or hyperglycemic effects in people with diabetes, alcohol should be consumed during meals. It has been shown that moderate amounts of alcohol ingestion (5-15g day) is associated with a decreased risk of coronary heart disease. The DNSG also agrees with the recommendation of moderate alcohol intake in diabetes (10g day for women, 20g day for men) provided that it is consumed during meals (especially by patients using insulin).

Pathophysiology of malnutrition

Obesity is a specialized form of malnutrition that is becoming increasingly common in children, raising concerns about type 1 diabetes, cardiovascular disease, and risk of cancer. A recent study has reported that low-grade inflammation, as determined by serum levels of high-sensitivity C-reactive protein, while significantly increased in children with type 1 diabetes, a high level was even more pronounced in apparently healthy juveniles with primary obesity 19 . Uncomplicated morbid obesity in adolescents may be accompanied by alterations in the levels of circulating T cells and cytokine response 20 . Other studies show that regulation of natural killer (NK) function and proliferative response to mitogens in vitro are affected 21, 22 . Leptin, the product of the ob gene, is a pleiotropic molecule that regulates food intake through metabolic and neuro-endocrine functions, has cyto-kine-like activities and is a major regulator of immune function 23 .

Unilateral transtentorial herniation

Distortion of the quadrigeminal plate region can lead to a paralysis of upward gaze (Parinaud's syndrome), and pituitary necrosis and diabetes insipidus may occur in exceptional cases. Although the syndromes of central and unilateral transtentorial herniation are clinically distinct in the early stages, both merge into a similar picture as rostral-caudal deterioration advances.

Fat metabolism in the healing wound

The need for proper nutrition to facilitate wound healing is a well-established paradigm in medicine.72-79 However, an understanding of the molecular, biochemical, and cellular processes that occur during wound healing is complicated by the fact that there are multiple types of both acute and chronic wounds. Acute wounds (e.g., surgical, trauma, or burns) require a different treatment regimen than chronic wounds (e.g., venous, pressure, or diabetic ulcers). Moreover, individuals with chronic wounds often have underlying disease or complicating factors that present additional challenges to healing (e.g., diabetes, obesity, frail geriatric patients). Although we have a good level of understanding about the effects of wounds on whole body energy metabolism, this data cannot be directly extrapolated to metabolism in the wound. The reason for this is that the wound functions within its own metabolic microenvironment.

Chylomicron metabolism the exogenous pathway

Chylomicrons Pathway

This enzyme is found in a number of tissues outside the liver, particularly adipose tissue, skeletal muscle and heart muscle. Its role in lipid metabolism has already been discussed (Sections 4.5.3.1 and 6.2.4.2). It is synthesised within the cells of the tissue (e.g. the adipocytes or the muscle fibres) and exported to the capillaries, where it is attached to the endothelial cells. Here it is bound (non-covalently) to highly negatively charged glycosaminoglycan chains such as heparan sulphate. LPL acts on lipoprotein particles passing through the capillaries, hydrolysing triacylglycerol molecules to release non-esterified fatty acids which may be taken up into the tissue for esterification (and hence storage - mainly in adipose tissue) or oxidation (in muscle). It can only do this if the particles contain apolipoprotein CII (see Box 9.1). LPL activity in adipose tissue is stimulated by insulin, over a relatively long time-course (a few hours).

Malnutrition syndromes of childhood

Low birth weight infants are classified as SGA (small for gestational age), which can also occur in full-term infants, or as AGA (appropriate for gestational age), which is the more common presentation of prematurity. Intrauterine growth retardation (IUGR) is usually associated with placental insufficiency, congenital infection, maternal smoking, exposure to toxins, or a combination of factors. In developing countries, IUGR can be caused by a prenatal deficiency of calcium, vitamin A, B1, and E and folate. Clinically, low birth weight infants, including AGA premature infants with no evidence of infection, have impaired cell-mediated immunity, diminished cytokine responses, and reduced phagocyte function 94-96 . SGA infants have smaller thymic glands and deficient cytokine responses relative to the AGA infants.

Donor Preoperative Management

A urinary drainage catheter is placed in all potential donors to monitor urinary output, assess renal function, and keep pace with the large urine output seen with diabetes insipidus which occurs in 50-70 of all organ donors. Although not always considered from the outset of the patient's hospital course, placement of a nasogastric tube is critical to help prevent aspiration in all potential lung donors. Early placement of a nasogastric tube should be stressed to all hospitals and organ procurement organizations caring for multi-organ donors. Following most forms of brain injury but prior to declaration of brain death, intravenous fluid is usually restricted in an attempt to limit cerebral edema and salvage any existing CNS function. This management, along with the nearly universal occurrence of diabetes insipidus due to pituitary nonfunction, may result in profound hypovolemia.

Dinoprostone Carboprost Tromethamine and Misoprostol

While adverse reactions are common following the use of abortion-inducing doses of the prostaglandins, most are not serious. Gastrointestinal disturbances include nausea, vomiting, and diarrhea. Transient fever, retained placental fragments, excessive bleeding, decreased diastolic blood pressure, and headache also have been noted. These drugs should be used with caution in patients with asthma, cervicitis, vaginitis, hypertension or hypotension, anemia, jaundice, diabetes, or epilepsy. They should not be used in patients with acute pelvic inflammatory disease, drug hypersensitivity, or an active renal, hepatic, or cardiovascular disorder. Since prostaglandins are potentially carcinogenic, if pregnancy is not effectively terminated following their use, another method should be used. The prostaglandins are not generally used concomitantly with oxytocin because of the possibility of uterine rupture.

Median Rhomboid Glossitis

Tongue Median Rhomboid Glossitis

Median rhomboid glossitis usually presents as a painless, reddened, sharply demarcated area of depapillation in the centre of the dorsum of the tongue anterior to the foramen caecum. In some cases the area is nodular or grooved. It was originally thought to be due to the persistence of the developmental eminence called the tuberculum impar, but now most cases are believed to be candidal in origin 180, 188 . Predisposing factors include smoking, wearing dentures, diabetes and using steroid inhalers. Sometimes there is a kissing lesion in the palate.

Pharmacologic options

Sibutramine produces a dose-dependent weight loss (available doses are 5, 10 and 15 mg capsules), with an average loss of about 8-10 of initial body weight at 6 months 28 . A greater proportion of participants achieve 5 and 10 weight loss on sibutramine than placebo in studies lasting 44 to 54 weeks 29-42 . Wadden et al. 32 demonstrated significantly greater weight reduction in patients combining pharmacotherapy with lifestyle modifications. Studies have demonstrated improvement in glycemic control in patients with type 2 diabetes 30, 33-35 and in cardiovascular risk factors 36-38 . Sibutramine can cause small increases in both blood pressure and pulse however, studies have shown sibutramine Orlistat is a synthetic hydrogenated derivative of a naturally occurring lipase inhibitor, lipostatin, produced by the mold Strepto-myces toxytricini. Taken at a therapeutic dose of 120 mg tid, orlistat blocks the digestion and absorption of about 30 of dietary fat.

Ampar Endocytosis In Ltd

Ampar Glur2

The regulated endocytosis, on the other hand, is specifically associated with AMPARs containing the GluR2 subunit28 . This GluR2 specificity is mediated by several sequence motifs uniquely present within the CT region of the subunit, including a middle domain that binds to both NSF and AP2 clathrin adaptor31 and a terminal PDZ-binding domain that interacts with a number of PDZ-containing proteins such as GRIP and PICK132 . In addition, systematic mutational analysis has recently identified a novel tyrosine phosphorylation-dependent endocytic motif (869 YKEGYNVYG877 ) in the GluR2 CT that is absolutely required for insulin-stimulated AMPAR endocytosis (Figure 32.1)30 . Figure 32.1. Schematic Diagram Shows the Amino-Acid Sequence in Carboxyl Terminal (CT) of AMPAR GluR2 Subunit.

Forms of cataracts in systemic disease

The typical diabetic cataract is rare in young diabetic patients. Transient metabolic decompensation promotes the occurrence of a typical radial snowflake pattern of cortical opacities (snowflake cataract). Transient hyperopia and myopia can occur. H Diabetic cataract progresses rapidly. Senile cataracts are observed about five times as often in older diabetics as in patients the same age with normal metabolism. These cataracts usually also occur two to three years earlier.

Fungal Wound Infections

Sphagnum Moss Infection

Fungal infections of wounds are unusual in economically developed countries, except that the yeast Candida albicans can be troublesome in severe burns and in those with wounds and underlying diseases such as diabetes and cancer. This yeast, commonly present among the normal flora and kept in check by it, becomes pathogenic when the competing microorganisms are eliminated, as in individuals receiving antibacterial therapy. Other fungal wound infections are much more common in impoverished people around the world. For example, Madura foot, a condition caused by various species of fungi, occurs in areas of the world where foot injuries are common, resulting from lack of shoes. Named after the city in India where it was first described, Madura foot is characterized by swellings and draining passageways that spit out yellow or black granules of fungal material.

Effecs Of Irr On Wound Healing

Glucose and fatty acids are the main oxidative fuels in the body and account for a majority of oxidative metabolism. There are still many questions that need to be answered about the interaction of glucose and fatty acid metabolism, especially the differences that may exist between the resting and exercise states. However, an understanding of energy metabolism in the body requires an examination of how these two pathways interact. Lipolysis and lipogenesis in adipose tissue and fatty acid oxidation in liver and skeletal muscle may be influenced by the type of fat, as indicated above, but they are also under the control of several hormones and transcription factors that regulate fatty acid metabolism Adipose tissue contains a hormone-sensitive lipase that is suppressed by insulin. An elevation in blood glucose stimulates insulin secretion, which suppresses the release of NEFA from adipose tissue TAGs.

Metabolic effects of catecholamines

Catecholamine Effects Urine

There is usually a balance between stimulatory and inhibitory effects, and in normal sedentary daily life it is probable that regulation of hormonesensitive lipase by insulin predominates. However, in response to any kind of stress, including exercise, there is activation of the P1 receptors so that lipolysis is stimulated. Blockade of the P receptors with the P-antagonist propranolol reduces, or may completely suppress, the liberation of non-esterified fatty acids into the plasma in response to exercise (Fig. 7.7). Activation of hormone-sensitive lipase can be brought about purely by mental stress. Stimulation of lipolysis is an important feature of the response to physical stresses such as surgical operations or injury. Again, it is not certain to what extent the direct innervation of adipose tissue is involved, or whether circulating adrenaline plays the major role.

Stimuli for activation of the sympathetic nervous system and adrenal medulla

Hermle Hypoglycemia 2019

A more severe stress, rarely met in everyday life but commonly studied in laboratories (because it is a reproducible test of responses to stress, unlike, for instance, trying to frighten someone ), is a rapid lowering of the concentration of glucose in the blood to produce the state of hypoglycaemia. Experimentally this is brought about by an injection of insulin. Outside the laboratory it can occur in certain metabolic diseases in which gluconeogenesis or glycogenolysis are impaired, or in people with diabetes who have injected too much insulin. Glucose receptors in the hypothalamus relay the information, and there is activation both of the sympathetic nervous system generally and of adrenaline secretion from the adrenal medulla (Fig. 7.6). We will see shortly how these responses act to restore a normal glucose concentration. Fig. 7.

Overview of nutrition and lipogenesis

Lipogenesis

In human WAT, de novo synthesis of fatty acids is quantitatively less important than in the liver. Rather, in the postprandial state, adipocytes synthesize triacylglycerol from fatty acids - derived from the action of lipoprotein lipase (LPL) on the lipoprotein (chylomicron, VLDL)-containing triacylglycerols - and glucose, which enters the adipocyte through insulin-regulated glucose transporter GLUT4 and whose intracellular metabolism produces the glycerol-3-phosphate needed for triacylglycerol synthesis (Fig. 4.3). Triacylglycerols are stored in the adipocytes, The traditional view is that low activity of the enzyme glycerol kinase in adipocytes ensures that triacylglycerol formation in these cells is dependent on an optimal supply of glucose, avoiding re-esterification under conditions in which fatty acids are to be exported, such as fasting.

Regulation of Vegfa Expression

Numerous growth factors, cytokines, and lipid mediators upregulate VEGF-A expression in different cells, including EGF, TGF-a, FGF-2, TGF-b, PDGF, keratinocyte growth factor, TNF, interleukins 1 and 6, insulin-like growth factor 1, HGF, and prostaglandins E1 and E2. These findings are likely to be important in autocrine regulation of VEGF-A VEGF-A is expressed by many cells that make steroid hormones (adrenal cortex, corpus luteum, Leydig cells) and by cells that are under hormonal regulation (e.g., the cycling uterus and ovary). Circulating VEGF-A levels and presumably VEGF-A expression correlate with estrogen receptor positivity in breast cancer. VEGF-A is also expressed by peptide hormone-producing cells such as thyroid follicular cells, and its production in culture is upregulated by agents such as insulin, dibutyryl c-AMP, and the IgG of Graves' disease.

Physiological factors influencing food intake

Chemoreceptors in the gastrointestinal tract detect the chemical presence of nutrients, and provide information on the composition of the foods consumed. Factors such as cholecystokinine (CCK) and glucagon-like peptide 1 (GLP-1) are released in response to the chemical presence of food in the gastrointestinal tract. CCK is a hormone released in the duodenum in response to consumption of fat (i.e. long-chain fatty acids) or protein (i.e. amino acids). GLP-1 is a hormone released in the blood by mucosal cells of the gut in response to the presence of carbohydrates and fat (Macintosh et al., 2001). CCK and GLP-1 suppress appetite by decreasing gastric emptying - by affecting the pyloric pressure, stomach motility and stomach muscle relaxation. By decreasing stomach emptying, the stomach distension increases, leading to sensations of fullness (Geliebter et al., 1988 Rolls et al., 1998).

Supervised versus unsupervised learning

Performance of these algorithms can be measured. However, there are several limitations which should be recognized. The classification algorithms' performance only pertains to the particular population or set of experiments on which it was originally tested. That is, a classification algorithm working on a yeast data set may not necessarily work as well relative to other algorithms on distinguishing two different types of leukemia or two different types of diabetes mellitus in humans. Even less dramatically, the same algorithm trained on one set of patients with leukemia may have a different relative performance compared to other classification algorithms on another set of leukemic patients drawn from a different population or obtained with a different ascertainment bias.

Carbohydrate and fat metabolism

Fat Carbohydrate Metabolism

The regulation of lipogenesis illustrates some useful points about metabolic regulation and its coordination in the whole body that were first brought up in the 'metabolic regulation puzzle' in Fig. 2.3. Fatty acids are synthesised from acetyl-CoA, and the pathway is stimulated by insulin, mainly by activation of the rate-controlling enzyme acetyl-CoA carboxylase (see Box 4.3). Acetyl-CoA may be produced from the breakdown of glucose, amino acids or fatty acids. What, then, prevents simultaneous fat oxidation, producing acetyl-CoA, and lipogenesis, reconverting acetyl-CoA to fatty acids That would represent a 'futile' and energy-wasting metabolic cycle. The first and easiest answer is that some important tissues do not carry out both these processes. Skeletal muscle has a high capacity for fatty acid oxidation, but it does not express fatty acid synthase. Adipose tissue has the capacity for fatty acid synthesis, but it seems hardly to oxidise fatty acids.

First Generation Sulfonylureas

The first-generation sulfonylureas are not frequently used in the modern management of diabetes mellitus because of their relatively low specificity of action, delay in time of onset, occasional long duration of action, and a variety of side effects. They also tend to have more adverse drug interactions than the second-generation sulfonylureas. They are occasionally used in patients who have achieved previous adequate control with these agents. Acetohexamide (Dymelor) is the only sulfonylurea with uricosuric activity, an action that may be of benefit in diabetic patients who also have gout. Chlorpropamide (Diabinese) has a relatively slow onset of action, with its maximal hypoglycemic potential often not reached for 1 or 2 weeks. Similarly, several weeks may be required to eliminate the drug after discontinuation of therapy. This drug can cause flushing, particularly when taken with alcohol, and can also cause hyponatremia.

General Aspects of Ovarian Function

Ovary Function

Thus, the corpus luteum is an outstanding model for investigating the regulation of microvascular growth in a normal, rapidly growing, highly metabolically active tissue. Understanding this process should also give us a much better understanding of what has gone wrong in various pathological conditions that are associated with abnormal tissue and microvascular growth, including tumor growth, various retinopathies, chronic varicose ulcers, and nonhealing fractures and wounds. In fact, we have just recently begun to apply our knowledge of microvascular growth in ovarian follicles and corpora lutea to the study of wounds in diabetics, which display delayed wound healing 3 .

Chronic Alcoholic Pancreatitis

Stages Alcohol Induced Pancreatitis

In CAP, islets appear in a variety of sizes and irregular shapes, particularly in fibrotic lesions. In fibrotic lesions, a depletion of B cells and a relative increase in A, D and PP cells are observed. Clinically, the risk of complication of diabetes mellitus is higher in CAP, and even higher in CAP cases with pancreatic stones.

Navy Physical Readiness

It is true that many people in the United States tend to gain weight with age, but it is not necessary that we do. Getting fatter as we get older is not without increased health risks. According to the 1995 Dietary Guidelines for Americans, it is recommended that we not allow our weight to increase as we age. Diseases associated with aging such as Type II diabetes, heart disease, and stroke are more prevalent in the obese population. For these reasons, the Navy does not allow increases in weight or body fat with age. Getting older is not an excuse for extra pounds

Treating Genetic Disease

For some diseases, physicians can implement symptom-prevention measures. For example, a physician might prescribe insulin injections to patients with diabetes. For patients with hemophilia, a doctor might prescribe injections of a missing blood-clotting protein. Physicians can even do some types of surgery to correct genetic defects in a fetus before birth.

Complications and comorbidities

Older patients with long-standing alcoholism are at high risk for development or aggravation of many medical problems, especially liver disease, several cancers, disorders of glucose, fat and uric acid metabolism, osteoporosis, anaemias, congestive heart failure, aspiration pneumonia, and accidental injuries. (7) Control of hypertension and diabetes mellitus is compromised by heavy drinking. Acute doses of alcohol compete with many medications (e.g. warfarin, phenytoin, most benzodiazepines, propanolol) for hepatic drug metabolizing enzymes in the cytochrome P-450 system, which can produce higher than desired drug blood levels, while chronic alcohol dosing induces the cytochrome P-450 system and can lead to more rapid metabolism of the same medications, with resulting lower than desired drug blood levels.(8) Inhibition of hepatic alcohol dehydrogenase by such drugs as chlorpromazine and isoniazid, or inhibition of gastric alcohol dehydrogenase by histamine receptor antagonists (e.g.

The overall control of protein synthesis and breakdown

Protein Breakdown Muscle

There are some generalisations that can be made about the regulation of protein synthesis and breakdown (summarised in Fig. 6.19). Two hormones have a general anabolic role (stimulating net protein synthesis) in the body insulin and growth hormone. In people with a deficiency of insulin (insulin-dependent diabetes mellitus see Chapter 10) there is marked loss of protein from the body - the 'melting of flesh into urine'. Treatment with insulin restores body protein. Growth hormone acts through the insulin-like growth factors IGF-1 and IGF-2, and has an important role during development. In the adult this is not of major importance adults whose pituitaries have been removed do not need growth hormone to be replaced to lead fairly normal lives. However, growth hormone is beneficial in stimulating protein anabolism in patients who have lost protein through severe illness. Fig. 6.19 Overall control of protein synthesis and breakdown in muscle (and other tissues).

Oxidation And Reduction Prooxidants And Antioxidants

Oxidative damage is considered to play an important role in the pathogenesis of several diseases. For example, patients with degenerative and chronic diseases - e.g. atherosclerosis, diabetes mellitus, joint diseases, cataract, or diseases of the respiratory system -suffer from increased oxidative stress (87). In healthy subjects, oxidative damage is largely prevented by a very complex antioxidant system, consisting of several enzymic and nonenzymic components, which act cooperatively to provide protection against free radical attack (91). Evidence from biochemical and animal models suggests that nutritional antioxidants should inhibit the development of diseases such as cardiovascular diseases and certain cancers (89).

Conclusion and Summary

These chemical agents have therefore been used for experiments on pancreatic acinar cell regeneration. On the other hand, the chemical agents which produce pancreatic endocrine cell destruction, such as alloxan 4 and strepto-zotocin 5-7 , have been used for various experiments on pancreatic endocrine regeneration, and it is also known that these chemical agents produce diabetic states in rats and guinea-pigs. Furthermore, studies on regeneration of pancreatic acinar cells and endocrine cells after partial or subtotal pancreatectomy of some experimental animals, have been reported 8 . My previous experiment on the characteristic histological patterns of regeneration in the chemically-injured animal pancreas suggested that pancreatic acinar cell regeneration followed by necrosis and destruction by DL-ethionine administration occurred as early as 3 days after the termination of DL-ethionine administration.

Ratio of Preganglionic to Postganglionic Neurons

When the sympathetic integrative centers in the brain are activated (by anger, stress, or emergency), the body's resources are mobilized for combat or for flight. Stimulation of the sympathetic nervous system results in acceleration of the heart rate and an increase in the contractile force of the heart muscle. There is increased blood flow (vasodilation) through skeletal muscle and decreased blood flow (vasoconstriction) through the skin and visceral organs. Activity of the gastrointestinal tract, such as peristaltic and secretory activity, is decreased, and intestinal sphincters are contracted. The pupils are dilated. The increased breakdown of glyco-gen (glycogenolysis) in the liver produces an increase in blood sugar, while the breakdown of lipids (lipolysis) in adipose tissue produces an increase in blood fatty acids these biochemical reactions make energy available for active tissues.

Pharmacogenetic Interactions in Hormone Replacement Therapy

Estrogen progesterone replacement therapy is associated with an increased risk for strokes and myocardial infarctions for premenopausal women with additional risk factors (smoking, hypertension, diabetes) (52) who use OCP, and for postmenopausal women taking HRT (46). However, there are inconsistent data regarding a pharmacogenetic interaction between FVL or PR20210 and OCP HRT and cardiovascular ischemic events (53,54).

Beef pork lamb and vealTotal fat grams

Research shows that a person's risk of developing heart disease and diabetes is greatly increased when fat is distributed above the waist, such as the abdomen area. Males tend to gain weight in the waist which places them at greater risk than females, who tend to gain weight below the waist. Sometimes this is called the apple or the pear referring to the shape of the body. The apple shape is not exclusively male. The hormonal changes of menopause tend to cause a shift of weight from the hips to the waist. In addition, women after the age of menopause are at increased risk of heart disease, like males. Chromium is a mineral which is required for normal lipid and carbohydrate metabolism and assists insulin with carbohydrate and protein metabolism. Chromium acts as part of the glucose tolerance factor and may improve glucose tolerance in chromium-deficient patients. Much work needs to be done before considering drug therapy with leptin in humans.

Peripheral Neuropathy

Peripheral neuropathy is ascribed when peripheral nerves are damaged. This condition is associated with impaired motor, sensory, and or autonomic nerve dysfunction, and may be either inherited such as in Charcot-Marie-Tooth (CMT) disease or acquired. Acquired neuropathies are commonly caused by leprosy (most common world-wide), other diseases (diabetes mellitus, autoimmune disorders, toxins such as alcohol or heavy metals) or nutritional deficiencies (B12 or thiamine). The prevalence of OSA in patients with peripheral neuropathy is unknown. This, in part, may be influenced by the underlying cause of disorder such as diabetes mellitus. In a group of nonobese diabetic patients, 30 demonstrated OSA (61). Patients with peripheral neuropathies such as CMT and familial dysautonomia are also predisposed to OSA (62,63). Sleep apnea may in itself pose a risk to the peripheral nervous system. Chronic hypoxemia is a known risk factor for polyneu-ropathy (64).

Maintenance of normoglycemia

Hyperglycemia is associated with a worsened outcome after ischemic cerebral injury. In conditions of insufficient oxygen supply, cellular energy requirements may be partially met by anaerobic glycolysis which leads to an accumulation of lactic acid. Since this is virtually all ionized at physiological pH an intracellular acidosis develops, leading to deregulation of ionic membrane pumps and the formation of other mediators of neuronal injury. This intracellular acidosis is the probable mechanism of the adverse effects of hyperglycemia in brain injury, although the evidence in focal ischemia is not as clear. Thus hyperglycemia enhances injury in the ischemic core, whereas damage in the penumbra may be reduced due to collateral flow. Significant hyperglycemia ( 10 mmol l) should always be corrected with insulin infusion in neurosurgical patients.

Management Of Hypotension

Hypotension is common in the organ donor and its etiology is multifactorial. Hypotension may result from iatrogenic causes such as inadequate fluid resuscitation or fluid replacement, causes related to brain death such as neurogenic diabetes insipidus and loss of central vasomotor control or ventricular dysfunction secondary to myocardial ischemia or traumatic injury. Endocrine failure as a cause of hypotension has received much attention recently. The mechanism and rationale for hormone replacement as treatment will be discussed elsewhere. Neurogenic Diabetes Insipidus Neurogenic diabetes insipidus is characterized by polyuria, hyperosmolality with a serum osmolarity greater than 295, a urine osmolarity less than 300 mOsm L and a urine specific gravity less than 1.005. Treatment requires aggressive replacement of urinary output for the previous hour together with hourly maintenance infusions.

Health Promotion And Disease Prevention

Comfort Zone Fear Learning Growth

The concept of disease prevention is more specific and comprises primary, secondary and tertiary prevention (12). Primary prevention is defined as preventing the disease or stopping individuals from becoming at high risk. Universal and selective preventive interventions are included in primary prevention. Universal primary prevention targets the general public or a whole population group without an identified specific risk (e.g. iodine supplementation programmes to prevent neurological and other disorders caused by iodine deficiency). Selective primary prevention targets individuals or subgroups of the population whose risk of developing disease is significantly higher than average, as evidenced by biological, psychological or social risk factors (e.g. prevention of stroke through adequate management of hypertension, diabetes and hypercholesterolemia).

Conjugated linoleic acid CLA

Interest in CLA arose, initially, in its anticarcinogenic action. However, CLA may have several other health benefits, including the reduction of body fat and an improvement of blood lipid profile in relation to the risk of cardiovascular diseases and diabetes (see reference 200). However, conflicting results on the effects of CLA have been reported depending on days of treatment, dose, animal species used and proportion of each isomer (reviewed in reference 201). Most of the experiments have used a mixture of different isomers, while it is increasingly evident that different CLA isomers have different or even opposite biological effects (e.g. see references 200 and 202). There is substantial evidence that the trans-10,cis-12 CLA isomer is responsible for the effects on body composition and lipid metabolism, whereas anticarcinogenic properties are mostly associated with the cis-9,trans-11 CLA isomer.

Perry Shen and Shayn Martin

Perry Shen

The metabolism of carbohydrates is altered by malignancy. Anaerobic glycolysis is favored by tumor cells, resulting in the production of lactate. Lactate is inefficiently recycled to glucose by gluconeogenesis in the Cori cycle. A substantial net loss of energy occurs through this wasteful process.7 Further altered carbohydrate metabolism includes reduced pancreatic insulin secretion as well as glucose intolerance, which is secondary to peripheral insulin resistance.8

Anterior Spinal Artery Syndrome

Anterior spinal artery syndrome occurs in middle-aged and elderly patients and affects both genders equally. Patients with hypertension and diabetes, two diseases that increase atherosclerosis, are more susceptible to spinal cord infarction. The syndrome may also develop in patients with dissecting abdominal aortic aneurysm, following aneurysm repair in patients with coagulopathies, vasculitis, or hypotension or during transforaminal steroid injection when the artery of Adamkiewicz is inadvertently penetrated.

Prevalence incidence and disease expectancy

Coping With Hallucinations

The question of whether major differences exist in the prevalence of schizophrenia in different populations has no simple answer. In the great majority of studies the prevalence rates are similar. On the other hand, there are a small number of populations that clearly deviate from the average. However, the magnitude of these deviations is modest compared with the 10- to 30-fold differences in prevalence observed in other multifactorial diseases (e.g. ischaemic heart disease, diabetes, multiple sclerosis) across populations.

The contribution of reduced thermogenesis and fat oxidation to obesity and its metabolic complications

Besides and beyond contributing to increased fat mass (obesity), decreased fat oxidation and thermogenesis may result in an excess of available fatty acids to muscle, liver, pancreatic p cells and other non-adipose cells. Lipid accumulation can lead to functional impairments in these cells (lipotoxicity), and has been related to the development of insulin resistance, type 2 diabetes and other pathologies linked to obesity and the metabolic syndrome (reviewed in references 37 and 38). Because the activity of the UCPs may facilitate fat oxidation in the organism (see Section 4.2.1), it may help avoiding lipid accumulation in non-adipose cells and derived lipotoxic-ity. For instance, intramyocellular fat accumulation is highly correlated with insulin resistance and may be prevented through the activity of muscle UCP3, which is normally up-regulated under conditions of high fatty acid supply to muscles.

Outcomes Of Kidney Transplantation

Two of the most useful national databases on kidney transplantation are the Scientific Registry of Transplant Recipients (SRTR) of the United Network for Organ Sharing, where data on all kidney transplants in the U.S. have been collected since 1987, and the United States Renal Data System (USRDS). The SRTR supports the ongoing evaluation of the scientific and clinical status of solid organ transplantation including kidney transplants. The SRTR contains information on over 200,000 transplant recipients. Funding comes from the Health Resources and Services Administration (HRSA), a division of the U.S. Department of Health and Human Services (DHHS). The SRTR is administered by University Renal Research and Education Association (URREA), a not for profit health research organization, in collaboration with the University of Michigan.

Adrenal Fatigue- The silent epidemic

I would say that most people in America today have some form of adrenal fatigue. That fact normalizes it and makes it hard to take it seriously. I now realize that many severe illnesses are becoming normal . Cancer, diabetes, heart disease, high blood pressure, these are all on the rise and common enough that they get a bit of a ho hum response from us when they come up. If these obviously severe issues don't get our attention anymore, it is hard for something like adrenal fatigue to really get through. Adrenal fatigue didn't get my attention until I had trouble functioning day to day. I hope that some of you aren't that far gone and can reverse things before you get there. Your adrenal glands are tiny pea sized glands located on your kidneys. Despite being tiny they are incredibly important. If your were to have your adrenal glands removed you would die without the hormones that they provide. Two of the hormones that they produce are cortisol and adrenalin.

Ginger for Losing Weight

FDA Food and Drug Administration does recognize ginger herb as pretty safe to use, although rarely but there has been known some side effects such as diarrhea, belching, heartburn and a mouth irritation. It also may cause hypoglycemia and hypotension so it's not recommended to people suffering from diabetes and those with low blood pressure. So the final proposal stands to be that the best results in weight loss with ginger is a combination of this herb with a restricted diet and a healthy exercise.

The cancer, dies when you eat these 7 foods .Time to start eating them

Evidence suggests, that it inhibits cancer, kills bacteria, viruses and fungi, increases lifespan in animals, improves the energy production of cells eliminate dangerous free radicals, increases glucose tolerance to diabetes, improves heart function, improves physical and mental status and concentration, repair damaged DNA prevents cell damages caused by nuclear radiation.225 ml of red wine delivers approximately 640 mcg of resveratrol, resveratrol supplements (which are often in combination with extracts from grape or other antioxidants) are usually taken in doses of 200-600 mcg per day. Studies have reported that varieties Bordeaux and Pinot Noir contain most of this valuable polyphenol.

Baking Soda - Is a Cure for Cancer

This fungus called Candida has the ability to break out of the intestine and get into the blood stream. It is practically everywhere in the body and outside on the skin as well. It is placed around the outer membranes of the cells, stopping receptor cites from their performing ( these are for insulin) for example. Origano oil and cinnamon are great at fighting candida. 25 of type 2- diabetes patients showed to improve after using cinnamon. Candida releases toxins and high amounts of sugar, there fore diabetic and cancer patients suffer more or can't make it compared to the others with normal sugar level.It is known that sugar generates acidity and acidity is a good environment for candida.

Why is this hidden from the public: the top 10 causes of cancer we use every day!

Aspartame is the main ingredient of artificial sweeteners . This very dangerous material is an industrial secrets kept from the public for years. It is found in almost every sweet product , chewing gums, loly pops, candies and sweets for children. It is a basic sweetener for products and medication for diabetic patients. Stay away from it and turn to wheat malts, stevia, maple syrup, honey or raw organic sugar.

Eat a Handful of These Seeds a Day To Prevent Cancer and Fight Many More Diseases

Based on the results described above, we propose that the major function of PCE-C pumpkin crude extract is not to stimulate -cells in the islets of Langerhans to increase insulin secretion, but ratherrestore the islets of Langerhans, repairing impaired islets or act as an insulin sensitizer to enhance insulin action by improving the insulin sensitivity of target tissues such as the liver, muscle and adipose tissue emphasis added . Pumpkin polysaccharides may also play an important role in the recovery of liver function and glucose utilization . The pumpkin seed extract didn't simply stimulate the production of insulin, it healed the parts of the pancreas that manufacture it and improves your body's ability to use the insulin.

Physical Effects of My Eating Disorder

Effects that aren't mentioned, are the long-term consequences of obesity. Think, for example, type 2 diabetes. I don't know where he found this so can't check the source, but my husband says that eating lots of sweets is now thought to actually lead to type 2 diabetes because of leading to a chronically elevated blood glucose level.

Top 5 iPhone Apps for Sleep Apnea

Description from iTunes Having trouble sleeping can result in more than just being drowsy during the day. Numerous studies have linked sleep apnea to many other serious health problems, including type 2 diabetes, cardiovascular disease and obesity. Healthy sleep can be just as important as living a healthy lifestyle when you're awake. So if you're not getting the sleep you need, it's important to understand what could be going on. ResMed is here to help. With ResMed's free Sleep App, you can find out your risk for sleep apnea, record and listen to your own sleep sounds, find your nearest sleep clinic and start taking the steps toward a healthier and happier you.

10 Warning Signs for Sleep Apnea

Sleep apnea is said to be as common as diabetes and can be quite serious, which means that it is important to diagnose if you or someone you know suffers from sleep apnea. The following is a list of common symptoms of sleep apnea. Keep in mind that just because you suffer from a few of these symptoms, that does not necessarily mean that you have sleep apnea. If you feel that most of these symptoms apply to you and you have a poor quality of sleep, contact your primary caregiver to set up a sleep test. Certain lifestyle choices or health characteristics put you at more risk than others. Some lifestyle choices are smoking and alcohol use, which predispose you to sleep apnea. Some health characteristics are obesity, diabetes and hypertension. If your body mass index (BMI) is 25 or above, which is in the overweight category, then you are either at a higher risk for developing sleep apnea or you already have it and your body is trying to communicate this to you.

New Nootropic Drugs - Meet the Ampakines

Eli Lilly Pharmaceuticals was the first company to bring Penicillin and human insulin to market and they have been focusing specifically on the LY Class of ampakine drugs. The LY class are biarylpropylsulfonamide derivatives and have been shown to be potent nootropics in animal models. Another interesting fact about this LY ampakine class is their apparent stimulation of BDNF protein which is huge in the formation of new neurons and synapses as well as long term memory. This could have some huge benefits for repairing damages to the brain.

6 Nootropics Show Promise In Combating Anxiety And Depression

Diabetes comes with an increased risk of depression, so scientists have spent a lot of time looking for ways to reduce these symptoms in diabetic patients. A study that was published earlier this year proved that Taurine, which is a free amino acid that naturally occurs in the brain, can actually reverse depressive behaviors. Test subjects that were given 100 mg of Taurine daily had improvements in their short-term memory, and they also exhibited far fewer symptoms of depression than the control group.

An Intro To Neurotransmitters And Cognition

Neurotransmitters can be classified into two distinct sets small-molecule transmitters and neuropeptides. Peptides are, of course, just protein chains, so a neuropeptide would be a protein chain that is endogenous to the brain. Small-molecule transmitters can also be subdivided into monoamines and amino acids. Neuropeptides include such important signalling chemicals as endorphins, insulin and oxytocin (the love molecule). Small-molecule transmitters generally act directly on neighboring cells, whereas neuropeptides have more subtle modulatory effects.

Corticosteroid Levels May Deplete the Effects of Racetam Nootropics

One of the most important and abundant glucocorticoids is cortisol. Cortisol has a large variety of important functions within the body. It is important for modulating blood sugar and the immune system as well maintaining the proper metabolism of fats, carbohydrates and protein. Cortisol carries a lot of essential functions in the body however extended release can cause a lot of negative interactions. It is released during times of stress to limit less important functions such as immune function and energy metabolism. It also works to block insulin and reduce sexual function amongst many other negative consequences

Advantages Offered by Dental Implants

There can also be a sensation that the implant is loose, or the implant body might loosen. These issues can be more common in people with uncontrolled diabetes or those who smoke. It can also be tough to clean around the implant sometimes, there may be numbness after surgery.

Technique of PCN

Brodel Line Kidney Stones

Septicemia is less common with genitourinary interventions than with biliary procedures, but the risk of periprocedural sepsis is increased in the elderly, in diabetics, in patients with indwelling catheters, stones, or ureterointestinal anastomosis, or in the clinical presence of infection (18,19). The organisms that commonly infect the genitourinary tract are gram-negative rods, such as Escherichia coli, Proteus, Klebsiella, and enterococcus. Antibiotic prophylaxis should ideally be based on culture results, but broad-spectrum antibiotics active against the common urinary pathogens, such as aminoglycosidae (e.g., gentamycin) in conjunction with ampicil-lin or cefazolin, or ceftriaxone (20), can be used in the absence of culture results. Antibiotics are best administered immediately prior to or less than two hours before the procedure (20). If given more than three hours prior to the procedure, the incidence of adverse infectious events increases fivefold (21).

Prostate Problems

Impotence is often a psychological problem more than a physical one. Drugs, tobacco, diabetes, and atherosclerosis can affect blood circulation which influences erectile ability. The herb yohimbe has been shown to improve erectile and ejaculatory activity. Hypnotherapy may also be beneficial. Ginseng and the Ayurvedic herb ash-waganda can enhance sexual energy.

Endometrial Cancer

Endometrial Cancer Stage Grade Mri

In the United Kingdom, endometrial carcinoma has an incidence of 4850 new cases per year, compared to 6820 per annum for ovarian cancer and 3240 for cervical cancer. There are approximately 990 deaths per year from uterine cancer in the UK. Endometrial carcinoma is the commonest gynaecological malignancy in the USA, and the American Cancer Society estimates that 39 300 new cases and 6600 deaths will occur in 2002. The disease predominantly affects postmenopausal women, peaking in the decade 55-65 years. The most frequent presenting symptom is abnormal vaginal bleeding or discharge. Asymptomatic tumours may be detected by cervical smear or as an incidental finding during pelvic ultrasound. Women at high risk include those with the hereditary nonpolyposis colorectal cancer (HNPCC) gene who usually develop endometrial cancer before the age of 50 years. Women on long-term treatment with Tamoxifen for breast cancer also have an increased risk of developing endometrial malignancy.

Mechanisms

Several growth factors have been correlated with breast cancer risk. In particular, insulin-like growth factor 1 (IGF-1), epidermal growth factor (EGF), and vascular endothelial growth factor (VEGF) are positively associated with breast cancer risk.82,83 Thus, if FS or the lignans can alter the level of certain growth factors, it may be one of the mechanisms of their anticancer effects. In one study, rats fed a 5 FS diet or its equivalent amount of SDG for 4 weeks had reduced serum IGF-1 compared to the control group.84 However, when the rats received a MNU carcinogen, only the 5 FS diet reduced serum IGF-1 levels. As described previously, a 5 FS diet reduced the MNU tumor invasiveness and grade 41 therefore, a reduction in IGF-1 may be a potential mechanism for reducing tumor progression.

Addison Disease

Addison disease is rare with an estimated annual incidence of 0.8 cases per 100,000 of the population in Western societies. It is due to bilateral destruction of the adrenal cortex. Formerly, the most common cause was tuberculosis. Most cases now are due to organ-specific auto-immune destruction and opportunistic infections such as histoplasmosis in patients with AIDS. Due to this, it is likely that the number of patients with Addi-son disease will increase significantly. Addison disease may be associated with autoimmune polyglandular deficiency type I (Addison disease, chronic mucocutaneous candidosis, hypoparathyroidism) and autoimmune polyglandular deficiency type II (Addison disease, primary hypothyroidism, primary hypogonadism, insulin-dependent diabetes, pernicious anaemia, vitiligo) 130 .

Conclusions

The last 10-20 years have seen the development and optimization of the technology of iontophoresis as a noninvasive method of drug delivery. Peptide and protein drugs (e.g., insulin and vasopressin) have been delivered iontophoretically without the pain and side effects associated with traditional subcutaneous injection (10,165,166). Iontophoresis also has the potential to revolutionize clinical diagnosis and monitoring procedures in that it offers an avenue for extracting information from the body without the need for invasive procedures (3,167,168). Iontophoresis is already used clinically in physical therapy clinics, and an allergy patch test is close to commercial reality (33,169).

Meglitinides

Though structurally unrelated to sulfonylureas, the meglitinide class of hypoglycemic drugs bind to the same KATP channel as do the sulfonylureas, but it is unclear whether they bind to the same SUR1 subunit within the KATP complex. As a class, the meglitinides are incapable of stimulating insulin secretion in nutrient-starved p-cells, but in the presence of glucose, they demonstrate hypoglycemic effects by augmenting the release of insulin. Consequently, meglitinides seem relatively unlikely to cause fasting hypoglycemia. Repaglinide (Prandin), a member of the meglitinide class, is approved for monotherapy or in combination with metformin. Repaglinide is taken before each meal, three times a day, and is rapidly absorbed it is metabolized by the liver and has a half life of an hour. Insulin levels transiently rise postprandially after repaglinide administration but generally return to baseline by the next meal.

The small intestine

Structure Single Villus

In addition, gastrointestinal hormones modulate the secretion of other hormones, particularly of insulin secretion from the pancreas. This means that the arrival of food in the gastrointestinal tract will amplify the secretion of insulin that is otherwise stimulated by a rise in the blood glucose concentration. This aspect of gastrointestinal hormone action will be considered more fully in Chapter 5 (Section 5.7). insects (in insects, it replaces glucose as the main blood sugar).

Thiazolidinediones

Thiazolidinediones (sometimes termed glitazones) are a novel class of drugs that were initially identified for their insulin-sensitizing properties. They all act to decrease insulin resistance and enhance insulin action in target tissues. Thiazolidinediones activate the nuclear peroxisome proliferator-activated receptor (PPAR) 7, a nuclear orphan receptor that is predominantly expressed in adipose tissue and to a lesser extent in muscle, liver, and other tissues. The endogenous ligand for the PPAR-7 receptor is postulated to be prostaglandin J2, and it appears to work by heterodimerizing with other nuclear receptors to modulate the expression of insulin-sensitive genes. Thiazolidinediones are readily absorbed from the gastrointestinal tract following oral administration and are rapidly metabolized by the liver. Plasma elimination half-life is 2 to 3 hours for rosiglitazone (Avandia) and slightly longer for pioglitazone (Actos).

The early phase

Glucose Starvation

We have already looked at the pattern of metabolism in very short-term starvation (Section 6.5.1), namely the postabsorptive state after overnight fast. A gentle decrease in the concentration of glucose in the plasma led to a small decrease in the ratio of insulin glucagon, stimulation of hepatic glycogenolysis and liberation of fatty acids from adipose depots. The availability of fatty acids in the plasma leads tissues such as muscle to use fat, and spare glucose, as their major metabolic fuel. The postabsorptive state leads into a phase sometimes called the gluconeogenic phase, lasting until the second or third day of absolute starvation. Liver glycogen stores are virtually depleted within 24 hours (Fig. 8.2), and therefore gluconeogenesis must come into operation to supply the requirements of the brain and other glucose-requiring tissues (e.g. erythrocytes). The main signal for this will again be the decrease in insulin glucagon ratio.

Liver metabolism

Liver Metabolism Ppt

Glucose transporter (Box 2.2), which is not responsive to insulin, and has a relatively high Km for glucose so that it normally operates well below saturation. In addition, because there are many transporters, there is a high maximal activity (Vmax ) for glucose transport. This means that the rate and direction of movement of glucose across the hepatocyte membrane are determined by the relative glucose concentrations inside and outside the cell. Within the hepatocyte, glucose is phosphorylated to form glucose 6-phos-phate - the initial step in its metabolism by any pathway - by the enzyme glu-cokinase. This enzyme belongs to the family of hexokinases (hexokinase Type IV), but differs from the other hexokinases found in muscle and other tissues in that it has a high Km for glucose (12 mmol l) and is not inhibited by its product, glucose 6-phosphate, at physiological concentrations.

The pituitary gland

Hormone Target Tissue

Adrenocorticotrophic hormone (ACTH) - sometimes called cortico-trophin - is a peptide hormone (of 39 amino acids) which acts on the adrenal cortex to stimulate release of glucocorticoids, particularly cortisol. ACTH is (like insulin) synthesised as a prohormone, but in this case a very large one called pro-opiomelanocortin (often abbreviated POMC). POMC is cleaved proteolytically to generate several biologically active peptides including 0-endorphin and met-enkephalin (natural ligands of the receptors for cocaine, and involved in feelings of well-being, e.g. in response to exercise), a-, 0- and y-melanocyte-stimulating hormones (acting on melanocytes to influence pigmentation) and ACTH. (The melanocyte-stimulating hormones may also have a role in appetite regulation see Box 11.1.) Growth hormone is a peptide hormone (of 190 amino acids in humans), sometimes called somatotropin because of its major role in regulating growth and development (somato- referring to the body).

The Exchange System

Originally designed for diabetics, the exchange system is a widely used method of meal planning. Foods are divided into six groups or exchanges on the basis of their carbohydrate, protein, and fat content. Similar foods are placed in the same group. Many commercial weight loss programs use exchanges.

White Adipose Tissue

Ppar Pathway White Adipose Tissue

Insulin + Glucose-(GLUT4 Insulin + Glucose-(GLUT4 Triacylglycerol in the plasma is present in the lipoprotein particles (covered fully in Chapter 9). The largest of these particles, which carry most of the triacylglycerol, are too big to escape from the capillaries into the interstitial fluid therefore, the adipocytes cannot take them up directly. There is an interesting mechanism to overcome this difficulty. Adipocytes produce the enzyme lipoprotein lipase, which hydrolyses the triacylglycerol in lipoprotein particles to release fatty acids, which can then diffuse into the interstitial space and so reach the adipocytes. Since lipoprotein lipase must act in the capillaries, it is exported from the adipocytes to the endothelial cells lining the capillaries of adipose tissue. Here it is attached by chains of the complex amino-glycan heparan sulphate, a carbohydrate with highly negatively charged sulphate groups to which the enzyme molecules attach through a charge interaction.

Pentamidine

Rapid drug infusion may produce tachycardia, vomiting, shortness of breath, headache, and a fall in blood pressure. Changes in blood sugar (hypoglycemia or hyperglycemia) necessitate caution in its use, particularly in patients with diabetes mellitus. Renal function should be monitored and blood counts checked for dyscrasias.

Drosophila

Bar Drosophila

Based on the size of the synaptic boutons and the anatomy of the arbors, the NMJs fall into three classes (Figure 3.1D)3 . Type I NMJs are characterized by short-terminal branches and large presynaptic release sites. Type II NMJs are characterized by long thin branches, numerous small neurotransmitter release sites, and contain a variety of vesicles including LDCV. Type III axon terminals comprise a small class of intermediate terminals. In larval stages, type I NMJs contain a convoluted specialization of the postsynaptic membrane opposed to the active zone called the subsynaptic reticulum (SSR). Glutamate receptors cluster in the muscle membrane at the postsynaptic site. Although glutamate is the major neurotransmitter and is present in all types of Drosophila NMJs, octopamine, proctolin, leukokinin I, and insulin have been implicated as additional neurotransmitters and can be found at a subset of Drosophila NMJs.

Biguanides

Biguanides are a group of oral hypoglycemic agents that are chemically and pharmacologically distinct from the sulfonylureas. One biguanide, phenformin, was briefly used in the United States more than 30 years ago but was withdrawn from the market because it produced severe lactic acidosis in some patients. Metformin (Glucophage) was used in Europe for many years before it was approved for use in the United States in 1995. Metformin is the only approved biguanide for the treatment of patients with NIDDM that are refractory to dietary management alone. Metformin does not affect insulin secretion but requires the presence of insulin to be effective. The exact mechanism of met-formin's action is not clear, but it does decrease hepatic glucose production and increase peripheral glucose uptake. When used as monotherapy, metformin rarely causes hypoglycemia.
