The penicillin-binding protein (PBP) 1b of Escherichia coli catalyses the assembly of lipid-transported N-acetyl glucosaminyl-beta-1, 4-N-acetylmuramoyl-L-alanyl-gamma-D-glutamyl-(L)-meso-diaminopimelyl+ ++- (L)-D-alanyl-D-alanine disaccharide pentapeptide units into polymeric peptidoglycan. These units are phosphodiester linked, at C1 of muramic acid, to a C55 undecaprenyl carrier. PBP1b has b...

background: the use of devices emitted microwave radiation such as mobile phones, wireless fidelity (wi-fi) routers, etc. is increased rapidly. it has caused a great concern; the researchers should identify its effects on people's health. we evaluated the protective role of vitamin c on the metabolic and enzymatic activities of the liver after exposure to wi-fi routers. material and methods: 70...

using gaussian 03, software the thermodynamic functions such as gibbs free energy, g, enthalpy, h, and entropy, s, of alanine and valine amino acids were theoretically studied at different solvents. first, the density functional theory (b3lyp) level with 3-21g, 6-31g and 6-31+g basis sets were employed to optimization of isolated alanine and valine amino acids in the gas phase. moreover, vib...

OBJECTIVE To compare liver histology in HCV RNA positive patients with normal and elevated Alanine Aminotransferase Level (AST). METHODS This Cohort (prospective) study was conducted at Civil Hospital Karachi from Jan 2007 to July 2007. Forty patients with positive HCV RNA were included. Their liver function tests were followed for three months. Those having normal ALT on three occasions were...

The aim of this study was to assess the effects vegetable oils on antioxidant capacity, blood lipid components and immune responses in chickens raised hot climate. In a completely randomized design, 300 chicks were assigned four treatments five replicates with 15 per each. highest concentration malondialdehyde found broilers fed palm oil (p < 0.05). Chickens corn had lowest those flaxseed en...

A study was conducted with an objective to compare the efficacy of bentonite (BT), Spirulina platensis (SP) and glucomannan mycotoxin binders (GMA) on aflatoxicosis in broiler breeders. Three levels of AF, three binders and combination of different levels of AF with binders were evaluated. The AF fed at the levels of 300, 400 and 500ppb for three periods, each with duration of three weeks in br...
