Chronic exposure (24-72 hrs) of pancreatic islets to elevated glucose and fatty acid leads to glucolipoxicity characterized by basal insulin hypersecretion and impaired glucose-stimulated insulin secretion (GSIS). Our aim was to determine the mechanism for basal hypersecretion of insulin. We used mono-oleoyl-glycerol (MOG) as a tool to rapidly increase lipids in isolated rat pancreatic ß-cells ...

Abstract The study investigates tert- butoxy alkanols (otherwise defined as polyol butyl ethers) that have vicinal and hydroxy groups in their molecules from the perspective of usability oxygenated additives for motor gasoline. A series propylene glycol mono- ether (PTBE) glycerol di- (di-GTBE) samples were prepared: PTBE by direct acid-catalytic alkylation diols with butanol, di-GTBE epichloro...

Glycerol is a promising feedstock for microbial cultivation and production of 1,3 propanediol (1,3 PDO). Here we report a newly isolated bacterial strain BA11 from soil, capable of fermenting glycerol to 1,3 PDO, and has been identified to be a strain of Klebsiella pneumoniae. Strain BA11 was fast growing showing peak 1,3 PDO production in 6 h of cultivation with productivity of 1.2 g/...

- verapamil produces a sustained contraction in isolated biventer-cervicis muscle of chickens between 2-8 days old. from cumulative dose-response curves, ed50 of was calculated for this effect of verapamil. when isolated chicken biventer-cervicis muscle was electrically stimulated, verapamil had no effect on twitch contractures but increased the base line tone of the muscle. glycerol treatment ...

The microbial communities inferred in silica sinter rocks, based on multiscale morphological features (fabrics and textures) the presence of lipid biomarkers their carbon isotopic composition, are evaluated Krýsuvík geothermal area Iceland. Close to vent environments (T > 75 °C pH 1.7‒3), stream floors capped with homogeneous vitreous crusts breccia levels, no distinct recognizable silicifie...

A quantitative model describing the kinetics of hydrolysis of rat chylomicron acylglycerols by bovine milk lipoprotein lipase has been developed using data from studies on rat lymph chylomicrons containing doubly labeled acylglycerols. The detailed analysis indicates that, in addition to hydrolysis from tri- to di-, di- to mono-, and monoacylglycerol to glycerol, and apparently direct hydrolysi...
