A comparative study was made on the tissue specific expression of glutathione transferases (GST) in brain and testis after
exposure of rat to phenobarbitol (PB) and β-methylcholanthrene (MC). Glutathione transferases, a family of multifunctional
proteins are involved in intracellular transport processes and in detoxication of electrophilic xenobiotics by catalyzing
reactions such as conjugation, isomerization, reduction and thiolysis. On purification, the yield of GST proteins by affinity
chromatography was 39% in testis and 32% in brain. The affinity purified testis GSTs were resolved by chromatofocusing into
six anionic and four cationic isozymes, and in brain glutathione transferases were resolved into four anionic and three cationic
isozymes, suggesting the presence of multiple isozymes with Yc, Yb, Yβ and Yδ in both of them. In testis and brain, these
isozymes at identical pI values showed variable functions with a battery of substrates and the cationic isozymes of brain
and testis showed identical properties in CHP (cumene hydroperoxide) at pH values of above 7.0. Substrate specificity studies
and immunoblot analysis of testis and brain proteins revealed that they play a predominant role in the detoxication of phenobarbitol
or β-methylcholanthrene. Expression of the isozymes in testis and brain on exposure to PB and MC indicated elevated subunit
variation. In both testis and brain, Yδ of π class was expressed on PB treatment and Yc of α class and Yβ of μ class was expressed
in MC treated testis and only Yc was predominantly expressed in MC treated brain. Thus these subunits expression is considered
as markers for carcinogenesis and specific to chemical toxicity under phenobarbitol and β-methylcholanthrene stress.

This paper emphases on analyzing and investigating the mechanical behavior of electro-rheological fluid (ERF) semi-active damper. Theoretical model was developed to describe the relationship between electric field and the resistance force of ERF flowing through two parallel plane electrodes. In the model, the pressure drop along electrodes was supposed to consist of two parts: one related with viscosity and the other related with dynamic yield shear stress. The concept of yield stress influence factor was developed in 相似文献

Cardiovascular complications are the major cause of morbidity and mortality in diabetic patients. An attempt has been made
to evaluate the risk factors for coronary heart disease in type II diabetics. In the present study the levels of fasting and
postprandial plasma glucose, total cholesterol, low density lipoproteins, triglycerides were high and the levels of high density
lipoproteins were low in the type II diabetics compared to controls. The markers of free radical induced injury i.e. malondialdehyde
and nitrite/nitrate were high while total antioxidant status a marker for antioxidant protection against reactive oxygen species
was low in diabetics compared to controls. The study therefore suggests the importance of assessing these markers of oxidative
stress and antioxidant capacity along with the other routine investigations in diabetic patients for initiating antioxidant
therapy in addition to primary and secondary preventive measures to mitigate the devastating consequences of diabetes leading
to coronary heart disease. 相似文献

Some time earlier1 we treated our readers to an exoteric narrative of special relativity’s kinematics in which we shunned the use of mathematical formulas. However, the simple and concise account presented then has left quite a few questions open, and we now present the promised sequel to supply the requisite answers. 相似文献
