Patients and Methods: Two groups OSAS patients [Group I: Mild-moderate OSAS, n:43; median apnea-hypopnea index: AHI, /hour:18], Group II: Severe OSAS, n: 25; AHI:41.6] and healthy control group [n:25, AHI: 3.6] were included in the study. Serum YKL-40 level was tested in serum samples taken after polysomnography in OSAS patients and control group. In addition, the association of serum YKL-40 le...

Objective: The instant of maximum slope (Tup) of the T wave in the unipolar electrogram is a well-established measure of repolarisation time (TR). Nevertheless, recent observations on positive T waves have caused a renewed debate. The purpose of this study was to elucidate the mechanism that leads to positive and negative T waves and to investigate which electrogram feature best predicts TR. Me...

Objective: Nearly 25% of IgA nephropathy patients progress to end-stage renal disease over a 20-25 year follow-up period. IgA containing immune complex stimulates oxygen free radical production by mesangial cells in vitro, which may mediate glomerular injury in this disorder. Therefore, we studied whether dietary supplementation with the antioxidant agent, vitamin E, attenuates renal damage in ...

many reports have been published about the biogenesis of silver nanoparticles using several plant extracts such as pelargonium graveolens (p.graveolens- geranium) and azadirachta indica (neem) but the capacity of their natural reducing constituents to form silver nanoparticles has not yet been studied. in this research the synthesis of silver nanoparticles using geraniol has been investigated. ...

A central problem in cellular immunology is the elucidation of the nature of the antigen receptor molecules on the surface of thymus-dependent lymphocytes (T cells). Antigen receptors on thymus-independent lymphocytes (B cel|s) are readily detectable and have been identified as being mainly monomeric IgM molecules (1-6). However direct attempts to demonstrate immunoglobulin (Ig) molecules on th...
