Decreased GABA receptor binding in the cerebral cortex of insulin induced hypoglycemic and streptozotocin induced diabetic rats.

Abstract: Hypoglycemia is the major problem to blood glucose homeostasis in treatment of diabetes and is associated with severe irreversible consequences including seizures, coma and death. GABAergic inhibitory function in the cerebral cortex plays an important role in controlling the excitability and responsiveness of cortical neurons. Present study analysed effects of insulin induced hypoglycemia and streptozotocin induced diabetes on the cortical GABA receptor binding, GABAAά1, GABAB receptor subtype expression, GAD and GLUT3 expression. Diabetic rats showed decreased [3H] GABA binding in the cerebral cortex compared to control while hypoglycemia exacerbated the decrease. GABA receptor subunits; GABAAά1, GABAB and GAD expression significantly decreased in diabetic rats whereas hypoglycemia significanly decreased the expression compared to diabetic. GLUT3 expression significantly up regulated during both hypo and hyperglycemia. Our results showed that hypoglycemia and hyperglycemia decreased GABAergic neuroprotective function in the cerebral cortex, which account for the increased vulnerability of cerebral cortex to subsequent neuronal damage during hypo/hyperglycemia.

Studies on the Cure Characteristics and Vulcanizate Properties of 50 / 50 NR /SBR Blend

Abstract: Blends of 50/50 natural rubber (NR) and styrene-butadiene rubber (SBR) are vulcanized using several conventional and semi-EV systems. The cure characteristics and vulcanizate properties are compared. The quantity and quality of crosslinks in each case are deciphered by chemical probes to correlated them with the vulcanizate properties.

Role of coagents in peroxide vulcanization of natural rubber

Abstract: The drawbacks of peroxide vulcanization can largely be overcome by introducing suitable co-curing agents (coagents) in the formulation. The role of various coagents, such as zinc diacrylat...

A Characterization of the Bivariate Exponential Distribution

Abstract: In this article a characterisation of the Gumbel's Bivariate Exponential Distribution is established on the basis of the properties of the conditional expectation of the component variables. The characterising property is proposed as the definition of lack of memory in the bivariate case.
