BACKGROUND: Adipose tissue is an important endocrine organ that secretes a number of adipokines, like Resistin (RETN); it's an adipocytes-secreted cytokine and has been proposed as a link between obesity and diabetes. Many resistin gene polymorphisms were described and their implication in obesity was controversial. This study was to investigate the prevalence of single nucleotide polymorphisms (SNPs) in RETN gene 420C/G; 44G/A; 62G/A; 394C/G and 299 G/A and their association with Resistin level and obesity in Tunisian volunteers...

C1q is the target recognition protein of the classical complement pathway and a major connecting link between innate and acquired immunity. C1q and the multifunctional tumor necrosis factor (TNF) ligand family is of similar crystal structures, are designated the C1q/TNF-related proteins (CTRPs) superfamily. They are involved in processes as diverse as host defense, inflammation, apoptosis, autoimmunity, cell differentiation, organogenesis, hibernation and insulinresistant obesity. In this study, three members of the CTRPs superfamily were isolated and characterized in Yalu River lampreys (Eudontomyzon morii), and are respectively named LaC1qC, LaCTRP1, LaCTRP9...

Polycystic ovary syndrome (PCOS) and weight excess exhibited metabolic abnormalities and elevated cardiovascular risk. Our objective was to assess metabolic and inflammatory profiles in women with PCOS associated to weight excess; 85 women were enrolled. Four groups were then identified with and without PCOS and/or weight excess. Hyperlipidemia was significantly more observed in the two groups with weight excess. In whom insulinresistance and high sensitive C reactive protein were also elevated. Abnormalities observed when PCOS and weight excess are associated would mimic these observed in isolated weight excess with some particularities...

The analysis of new data concerning the development of pathology due to the community of evolutionary new pathological factors was done. Author provides the comparison of well-known and new definition for "metabolic syndrome" and diagnostic criteria of this pathology. The conception for permanent activation of nuclear factor kbeta as possible typic pathological process was discussed. Suppose that NF-kbeta is the possible key molecule in the initiation and formation of "vicious circle"--insulinresistance--inflammation--atherosclerosis...

Prostate cancer is one of most frequent malignant tumours at men. The androgen-deprivation therapy is the part of cancer treatment. It could be used both in the early stage of prostate cancer and in the bone metastates. From this reason the antiandrogen drugs waste systematically grows. Unfortunately androgen-deprivation therapy has numerous side effects such as: the inferior quality of live, sexual disturbances, the fatigue, the anaemia, the bone mineral density loss and the increase of the risk of breaks the bone, the increase of body mass, insulinresistance, hypercholesterolemia, the increase risk of cardiac disorders...

Non-alcoholic fatty liver disease (NAFLD) covers a spectrum of liver disease from steatosis to non-alcoholic steatohepatitis (NASH) and cirrhosis. Most NAFLD patients are hyperinsulinaemic and more insulin resistant compared with nonsteatotic healthy subjects, and there is a near universal association between NAFLD and insulinresistance (IR) irrespective of obesity. The metabolic syndrome (MS) is highly prevalent in the general adult population (approximatively 22%) and it carries an increased cardiovascular morbidity and mortality...

BACKGROUND: Hypertension is a condition normally detected in people with type II diabetes.It eventually leads to cardiovascular diseases in the patient. Visfatin is an adipocytokine which issecreted from adipose tissue and can affect the inflammatory reaction and also serum lipidlevels. Additionally, omega-3 inhibits the accumulation of fat and formation of insulinresistance. The current study tried to investigate the effects of omega-3 on blood pressurecompared to placebo and the relationship between serum visfatin levels and blood pressure...

Preoperative fasting is a currently adopted measure since Mendelson's report pertaining to aspiration pneumonia as a cause of death following general anesthesia. From a metabolic point of view fasting is detrimental because surgery in itself causes a state of hypercatabolism and hyperglycemia as a result of insulinresistance. Preoperative fasting has become almost obsolete in certain elective surgical procedures. In these cases the use of clear liquids is now well established and this paper focuses on the safe use of clear fluids, postoperative insulinresistance, patient comfort and postoperative outcome as well as its effect on the length of stay...

Myotonic dystrophies (DMs) are autosomal dominant disorders with multisystemic clinical features. DMs are categorized as DM1, caused by a (CTG)n expansion mutation in 19q13, and DM2, caused by a (CCTG)n expansion mutation in 3q21. The clinical features of DM2 are diffuse and proximal dominant weakness, wasting, myotonia, cardiac problems, cataracts, and insulinresistance. DM2 is milder than DM1. We compared the clinical features of both DMs and studied a Japanese patient with DM2 who had expansion mutations different from those usually attributed to the disease and originally discovered by European researchers...

Hypertension is the main disease in Russian Federation--its frequency is 39.2% in men and 41.1% in women. In recent years course of a disease is accompanied by the metabolic derangements which form the metabolic syndrome. In the basis of pathogenesis of hypertension are insulinresistance and compensatory hyperinsulinemia in combination with associated metabolic derangements. Inveterate insulinresistance leads to hypertension.

UNLABELLED: Nonalcoholic fatty liver disease (NAFLD) is a clinicopathological condition which ranges from simple steatosis and steatohepatitis to cryptogenetic cirrhosis. As insulinresistance plays a central pathogenetic role, NAFLD is regarded as the hepatic feature of the metabolic syndrome. Type 2 diabetes mellitus and obesity are the conditions most frequently associated with NAFLD. Subclinical inflammation has been suggested as a possible connective mechanism between glycoregulation disorders and NAFLD...
