Metabolism of inositol phospholipids and phosphatidylcholine was investigated in tracheobronchial epithelial cells exposed to mitogenic concentrations of crocidolite asbestos. Alterations in levels of diacylglycerol, the endogenous activator of protein kinase C, and inositol polyphosphates, presumed mobilizers of intracellular calcium, were examined. Cultures labeled with [3H]glycerol and expos...

BACKGROUND Metabonomics is a useful tool for studying mechanisms of drug treatment using systematic metabolite profiles. Ginsenosides Rg1 and Rb1, ophiopogonin D, and schizandrin are the main bioactive components of a traditional Chinese formula (Sheng-Mai San) widely used for the treatment of coronary heart disease. It remains unknown the effect of individual bioactive component and how the mu...

Background Biodiesel, an alternative energy source, has been attracting increasing worldwide interest in recent decades. It is obtained by base-catalyzed transesterification, resulting in a final mixture consisting of mono-alkyl esters and other by-products (e.g. glycerol, alcohol, free fatty acids). This composition provides a level of operational quality control that enables biodiesel to be m...

The wheat straw as abundant lignocellulosic resource was successfully undergone in a benzylation reaction and plasticized with different contents (2.5, 3, 5 and 7 wt. %) of glycerol and stearic acid.The effect of type and concentration of plasticizers on the mechanical, thermomechanical, morphological and water absorption properties of Benzylated Wheat Straw (BWS) was investigated ...

Background Cryopreservation procedure for poultry semen is not reliable due to structural and biochemical damages which can lead to reduction in sperm quality and fertility. Development of cryopreservation medium has crucial effects for successful recovery of sperm after freezing. The objective of this study was assessment of cryopreservation of rooster semen using hand-made cryopreservation me...

The tremendous mounting interest in lipase production is pertinent to the biotechnological applications that these enzymes offer. Lipase, belonging to the hydrolyze enzymes, is involved in copious biological functions including: hydrolysis insoluble triacylglycerol to mono and diacylglycerols and glycerol. Submerge fermentation technique was applied for the efficient production of this. Briefly...
