introduction: the most important virulence factor of brucella is related to its capability of intraphagocytic survival. brucella with this ability,causes persistant infection in host. garlic extract, because of has organosulfur compounds such as allicin, has antimicrobial activity. the aim of this study was to investigate the effect of garlic choloroformic extract on intramacrophage brucella sp...

introduction: the osteopetrosis is a common disease in man and animals which is characterized by calcium accumulation in bones. the purpose of this study is to eveluate the osteoblast ultrastructure in osteoptrotic op/op mouse. material and methods: in this study 5 op/op (experimental) and 5 control mouse were killed by overdose of choloroform. their femur bones were taken, decalcified by edta,...

We have evaluated the NMR shielding tensors for A:T,G:C,A:U in Watson-crick, and U-quartet. We have computed NMR shielding tensors at B31YP level by using 6-31G(d) basis set. We have compute anisotropy and asymmetry in A:T,G:C,A:U and U-quartet. The NMR shielding tensors were calculated using the GIAO method. The natural bonding orbital analysis (NBO) were performed. NBO calculation have been ...

often an important process in industry and chemical analysis. Liquid-membrane transport in which the extraction and stripping operations are combined in a single process reduces the solvent inventory requirement, and also allows the use of expensive and highly selective extractions, which otherwise would be uneconomic in solvent extractants. For these reasons, liquid-membrane transport has attr...

Flavonoids are among the most widely distributed natural products in plants with 2000 different compounds occuring in free forms or as glycosides. They have assigned differant roles in nature as signalling molecules. The major and general structures are Flavones, Flavonones, Flavonols, Isoflavones and Anthocyanidin. Methylated, acylated, prenylated or sulfated derivatives can also be met. Flavo...

PP2A is protein phosphatase-2A. Inhibition of PP2A (by PP2A inhibitors 1 and 2) results in hyperphosphorylation and accumulation of tau protein. Hyperphosphorylated tau is a major component of neurofibrillary tangles – a pathological hallmark of Alzheimer’s Disease (AD). Hence PP2A inhibition represents a putative new approach for a rodent model of AD. The goal of this study was to evaluate the...
