The usefulness of computed tomography (CT) for the diagnosis of feline hepatic lipidosis (FHL) was evaluated. Liver CT number was 54.7+/-5.6 HU (mean+/-SD) in 26 healthy cats. We fast 6 healthy cats for 72 hr to induced FHL experimentally and the cats were assessed by CT and serum biochemical analysis. Liver CT number of the six cats was 53.8+/-3.0 HU before fasting, 46.8+/-2.4 HU after fasting...

Peroxisome Proliferator Activated Receptors (PPAR) are members of the nuclear receptor superfamily of ligand activated transcription factor consisting of 3 subtypes PPARα , PPARβ and PPARγ. PPARγ plays an important role in adipocyte differentiation and it regulates lipid metabolism as well as insulin sensitivity. Of the 3 isoforms of PPARγ, PPARγ2 are expressed in adipose tissue. Genomic DNA wa...

PURPOSE To evaluate the effect of Ramadan fasting on parameters of insulin resistance in trained athletes at rest and after aerobic exercise. METHODS Nine male rugby players (age 19 +/- 2 yr, height 1.78 +/- 0.74 m) were tested 3 times: 1 week before observance of Ramadan (C), at the end of the first week (R1), and during the fourth week (R2). They performed a progressive cycle-ergometer test...

BACKGROUND Urotensin II (UII) is a potent vasoconstrictor peptide, which signals through a G-protein coupled receptor (GPCR) known as GPR14 or urotensin receptor (UTR). UII exerts a broad spectrum of actions in several systems such as vascular cell, heart muscle or pancreas, where it inhibits insulin release. OBJECTIVE Given the reported role of UII in insulin secretion, we have performed a g...

Restricted feeding (RF) during daytime is associated with anticipatory activity before feeding, marked hyperphagia after mealtime, adjustments in hepatic metabolism, and the expression of a food-entrained oscillator (FEO). 24 h rhythmicity of liver PPARα, β, and γ, peroxisomal markers (PMP70, AOX, and catalase), and free fatty acids (FFAs) during RF was evaluated. The effect of fasting-refeedin...

The hyperinsulinism/hyperammonemia (HI/HA) syndrome is a rare autosomal dominant disease manifested by hypoglycemic symptoms triggered by fasting or high-protein meals, and by elevated serum ammonia. HI/HA is the second most common cause of hyperinsulinemic hypoglycemia of infancy, and it is caused by activating mutations in GLUD1, the gene that encodes mitochondrial enzyme glutamate dehydrogen...

–The effect of Ramadan fasting on renal function markers, serum electrolytes and cardiovascular parameters at basal conditions and after a simulation of a rugby sevens match was studied in twelve recreational rugby sevens players. Three matches were played: one day before Ramadan (before Ramadan), at the end of the first week of Ramadan (Beg-R) and at the end of Ramadan (End-R). Before and imme...

Introduction: The long time use of opium has some effects on serums biochemical factors, the determination of this variation is a new approach in understanding off addiction and relive of drug abuser health. Hence in this study, these indicators in person who were withdrawing of opium have been studied. Materials and Methods: In this cross-sectional study bloods biochemical factors such as fast...

OBJECTIVE Serotonin mediates vasoconstriction and induces the activation of platelets, which may promote atherosclerosis. The aim of this study was to investigate whether plasma 5-hydroxyindole-3-acetic acid (5-HIAA; a derivative end product of serotonin) concentrations are high in subjects with metabolic syndrome (MetS) and to investigate the relationship between plasma 5-HIAA concentrations a...

INTRODUCTION Non-alcoholic (NAFLD) encompasses a spectrum of disease states, from steatosis (fatty liver) to non-alcoholic steatohepatitis (also called NASH steatosis with inflammatory changes) followed by progression to fibrosis and cirrhosis and hepatocellular carcinoma Excess liver fat is believed to be a manifestation of the metabolic syndrome and not surprisingly NASH is associated with ob...
