BACKGROUND The CD1 family is less variable transmembrane antigen presenting molecules related to the MHC molecules. CD1a and CD1e genes are the most polymorphic ones associated with autoimmune diseases. The aim was to better clarify the map of CD1 genes in Southwest Iranian normal population for implications in vaccine design. METHODS In this study we investigated the polymorphism of CD1a, CD...

In this century two great discoveries have shaken our view of the Indo—European family tree and protolanguage. The first was the discovery of Hittite, which in turn revealed the existence of an Anatolian branch of Indo—European; the second was the discovery in Central Asia of languages belonging to the previously unknown Tocharian branch of the family. Yet as important as these are, they are no...

We tested the hypothesis that exercise training (Ex) attenuates the effects of hypercholesterolemia on endothelium-dependent relaxation in left anterior descending coronary arteries. Adult female pigs were fed a normal-fat (NF) or high-fat (HF) diet for 20 wk. Four weeks after the diet was initiated, pigs were trained or remained sedentary (Sed) for 16 wk, yielding four groups of pigs: 1) NF-Se...

Because the regulation of vascular function involves complex mutual interactions between nitric oxide (NO) synthase (NOS) and cyclooxygenase (COX) products, we examined the contribution of NO and prostanoids derived from the COX pathway in modulating aortic baroreceptor resetting during an acute (30 min) increase in arterial pressure in anesthetized rats. Increase in pressure was induced either...

L-NAME (LN) induces hypertension by blocking nitric oxide (NO) synthesis. It produces vascular hyperreactivity to phenylephrine (PHE) associated with a reduced vascular Na+, K+-ATPase activity. The aim of this work was to investigate whether products of the cyclooxygenase pathway are involved in alterations of vascular reactivity and Na+-pump activity in the tail artery from LN-induced hyperten...

A growing body of experimental evidence suggests that neutrophilic polymorphonuclear leukocyte (PMN)-endothelial cell interactions play a critical role in the pathophysiology of nonsteroidal anti-inflammatory drug (NSAID)-induced gastropathy. The objective of this study was to directly determine whether the expression of endothelial cell adhesion molecules is enhanced in a model of NSAID-induce...
