Effect of stimulation of glucokinase (GK) export from the nucleus by small amounts of sorbitol on hepatic glucose flux in response to elevated plasma glucose was examined in 6-h fasted Zucker diabetic fatty rats at 10 wk of age. Under basal conditions, plasma glucose, insulin, and glucagon were approximately 8 mM, 2,000 pmol/l, and 60 ng/l, respectively. Endogenous glucose production (EGP) was ...

ease concurrently receiving #-adrenergic blocking agents. To investigate this possibility, 20 patients with coronary artery disease and normal left ventricular function receiving chronic propranolol therapy were given i.v. verapamil (0.025, 0.05, or 0.1 mg/kg over 2 minutes, followed by 0.005 mg/kg/min infusion) and the hemodynamic and angiographic effects were studied. The mean (± SD) plasma v...

Objective(s): Gallic acid (GA) is a highly effective antioxidant, which its beneficial effects are well known, but its impact on expression of microRNAs (miRs) following hepatic ischemia-reperfusion (I/R) is not well recognized. Therefore, the current research was designed to specify the beneficial effect of GA on miRs (122 and 34a), liver functional tests, and histopathological alterations bey...

Corn samples and different dry-milled fractions collected from an industrial mill in Argentina were analysed. Average contaminations were FB(1) 1540 microg kg(-1), FB(2) 716 microg kg(-1) and FB(3) 152 microg kg(-1) in whole corn; FB(1) 135 microg kg(-1), FB(2) 39.1 microg kg(-1) and FB(3) 10.2 microg kg(-1) in corn grits; FB(1) 358 microg kg(-1), FB(2) 122 microg kg(-1) and FB(3) 45.9 microg k...

Monitoring of nitrate (NO(3)(-)) and nitrite (NO(2)(-)) content in agricultural products in Slovenia has been carried out since 1996. The results of monitoring over the period 1996-2002 are presented. During this time 924 samples of 14 different agricultural products (potato, lettuce, apples, carrot, silage maize, cabbage, grapes, peaches, string beans, cereals, pears, cucumbers, strawberries a...

Four monofloral honeys, obtained from the Sicilian black bee by foraging on thistle, sulla, chestnut and eucalyptus, were studied. Results showed that phenolic composition of honey was highest (316 mg gallic acid equivalent GAE/kg), while sulla lowest (122 GAE/kg). Data confirmed a correlation between total phenol content colour intensity in honey, which darkest four samples. Sulla antioxidant ...

The present study aims to explore the possible mechanisms underlying the multidrug resistance characteristic of Cryptosporidium parvum by detecting the presence of ATP-binding cassette (ABC) protein encoding genes, especially one that shows high similarity to members belonging to the multidrug resistance protein (MDR) and multidrug resistance associated protein (MRP) subfamilies. PCR using ABC-...
