objective: type 2 diabetes (t2d) as a complex disease is the result of genetically heterogeneous factors and environmental issues interaction. linkage and small-scale candidate gene studies were successful in identification of genetic susceptibilities of monogenic form of diseases. however, they were largely unsuccessful while applying to the more common forms of disease. by designing genome wi...

Spontaneously hypertensive rats (SHR) demonstrate elevated blood pressure, cardiac hypertrophy, glucose intolerance, and insulin resistance compared with age-matched Wistar-Kyoto rats (WKY). We investigated concurrent effects of captopril on blood pressure, cardiac mass, myocardial enzyme activities, glucose tolerance, and insulin action in young male SHR. At 10 weeks of age, SHR were randomize...

Amino acids interact with glucose metabolism both as carbon substrates and by recycling glucose carbon via alanine and glutamine; however, the effect of protein intake on glucose homeostasis during weight loss remains unknown. This study tests the hypothesis that a moderate increase in dietary protein with a corresponding reduction of carbohydrates (CHO) stabilizes fasting and postprandial bloo...

To investigate the relationships between the sympathetic nervous system (SNS) and parameters of glucose metabolism in arterial hypertension, daily urinary excretion of catecholamines and plasma glucose, insulin, and C-peptide response to an oral glucose load (OGL) have been evaluated in 77 untreated patients with mild-to-moderate essential hypertension and in 31 normotensive controls. Urinary e...

Previous studies in mice suggest that portal venous infusion of glucose at a low rate paradoxically causes hypoglycemia; this does not occur in dogs, rats, and humans. A possible explanation is that fasting status in the mouse studies may have altered the response. We sought to determine whether the response to portal glucose delivery in the mouse was similar to that seen in other species and w...

Aqueous, ethanolic and hexane extracts of the leaves of Nauclea latifolia (Rubiaceae) were assessed for their fasting blood glucose lowering effect in normoglycaemic and streptozotocin-diabetic rats. Wistar strain albino rats were given different doses of the extracts after 18 hrs fast and their blood glucose measured at 0, 1, 2, 4 and 6 hours after treatment. The aqueous and ethanolic extracts...

ABSTRACT This study aimed evaluate energetic mobilization in tambaqui submitted to fasting, after a one-day refeeding. 120 juveniles were distributed 12 310L polyethylene boxes. Three treatments evaluated: Control (14 days of feeding); Fasting for 14 days; and Refeeding (13 fasting one day feedback). After the experimental period, fish anesthetized with eugenol blood collection serum plasma use...
