Insulin is a peptide hormone, secreted by the pancreas, that regulates glucose metabolism in the body. Insufficient production of insulin or failure of insulin to stimulate target sites in liver, muscle, and adipose tissue leads to the serious metabolic disorder known as diabetes mellitus. Diabetes afflicts millions of people worldwide. Diabetic individuals typically exhibit high levels of glucose in the blood, but insulin injection therapy allows diabetic individuals to maintain normal levels of blood glucose. 

Diabetes mellitus. A defect in carbohydrate metabolism leading to the appearance of sugar in the urine. 

Knockout mice have been reported for several FATPs [1]. As insulin desensitization has been closely linked to excessive fatty acid uptake and intracellular diacylgly-cerol and TG accumulation, these animal models were particularly evaluated in the context of protection from diet-induced type 2 diabetes ( Type 2 Diabetes Mellitus (T2DM)). In addition, studies on human subjects have also established genetic links between polymorphisms in FATP genes and metabolic alterations [1]. 

Disorders of lipoprotein metabolism involve perturbations which cause elevation of triglycerides and/or cholesterol, reduction of HDL-C, or alteration of properties of lipoproteins, such as their size or composition. These perturbations can be genetic (primary) or occur as a result of other diseases, conditions, or drugs (secondary). Some of the most important secondary disorders include hypothyroidism, diabetes mellitus, renal disease, and alcohol use. Hypothyroidism causes elevated LDL-C levels due primarily to downregulation of the LDL receptor. Insulin-resistance and type 2 diabetes mellitus result in impaired capacity to catabolize chylomicrons and VLDL, as well as excess hepatic triglyceride and VLDL production. Chronic kidney disease, including but not limited to end-stage... 

Insulin and the oral antidiabetic dmgi, alongwith diet and exercise are die cornerstones of treatment for diabetes mellitus. They are used to prevent episodes of hypoglycemia and to normalize carbohydrate metabolism. 

A knowledge of normal metabohsm is essential for an understanding of abnormalities underlying disease. Normal metabolism includes adaptation to periods of starvation, exercise, pregnancy, and lactation. Abnormal metabolism may result from nutritional deficiency, enzyme deficiency, abnormal secretion of hormones, or the actions of drugs and toxins. An important example of a metabolic disease is diabetes mellitus. 

On consideration of the profound derangement of metabolism in diabetes mellitus (due in large part to increased release of free fatty acids from the depots) and the fact that insuHn to a large extent corrects the condi-...

Non-alcoholic fatty liver disease begins with asymptomatic fatty liver but may progress to cirrhosis. This is a disease of exclusion elimination of any possible viral, genetic, or environmental causes must be made prior to making this diagnosis. Non-alcoholic fatty liver disease is related to numerous metabolic abnormalities. Risk factors include diabetes mellitus, dyslipidemia, obesity, and other conditions associated with increased hepatic fat.26... 

O Diabetes mellitus (DM) describes a group of chronic metabolic disorders that are characterized by hyperglycemia and are associated with long-term microvascular, macrovascular, and neuropathic complications. 

Differential diagnoses include diabetes mellitus and metabolic syndrome because patients with these conditions share several similar characteristics with Cushing s syndrome patients (e.g., obesity, hypertension, hyperlipidemia, hyperglycemia, and insulin resistance). In women, the presentations of hirsutism, menstrual abnormalities, and insulin resistance are similar to those of polycystic ovary syndrome. Cushing s syndrome can be differentiated from these conditions by identifying the classic signs and symptoms of truncal obesity, "moon faces" with facial plethora, a "buffalo hump" and supraclavicular fat pads, red-purple skin striae, and proximal muscle weakness. 

Fifth, the increased risk of obesity and diabetes mellitus in Hispanics warrants careful consideration of SGA use in this population. Although there is variance in the data from studies assessing the incidence of metabolic syndrome in Hispanics being administered SGAs, one study pointed to a significantly higher incidence compared to non-Hispanics. Further research in this area is warranted. 

Chemoreceptor response to increased arterial hydrogen ion concentration. An increase in arterial hydrogen ion concentration, or a decrease in arterial pH, stimulates the peripheral chemoreceptors and enhances ventilation. This response is important in maintaining acid-base balance. For example, under conditions of metabolic acidosis, caused by the accumulation of acids in the blood, the enhanced ventilation eliminates carbon dioxide and thus reduces the concentration of H+ ions in the blood. Metabolic acidosis may occur in patients with uncontrolled diabetes mellitus or when tissues become hypoxic and produce lactic acid. An increase in arterial hydrogen ion concentration has no effect on the central chemoreceptors. Hydrogen ions are unable to cross the blood-brain barrier. 

Secondary hyperlipoproteinemias, which arise from a disordered lipid tissue metabolism or its impaired control, are observed in diabetes mellitus, thyroid gland hypofunction, alcoholism, etc.
