background: unsafe transfusion practices put patients at high risk of transfusion transmissible infections. we aimed to evaluate the prevalence of transfusion transmissible infections (including human immunodeficiency virus [hiv] 1 and 2, hepatitis b virus [hbv], hepatitis c virus (hcv) and syphilis) during a period of 18 months among blood donors in the blood bank of lady hardinge medical coll...

Numerous studies have provided clues about the ontogeny of lateralization of auditory processing in humans, but most have employed specific subtypes of stimuli and/or have assessed responses in discrete temporal windows. The present study used near-infrared spectroscopy (NIRS) to establish changes in hemodynamic activity in the neocortex of preverbal infants (aged 4-11 months) while they were e...

Intestinal epithelial cells (IECs) are continuously exposed to large numbers of commensal bacteria but are relatively insensitive to them, thereby averting an excessive inflammatory reaction. In this study, we show that the low responsiveness of human IEC lines to LPS was mainly brought about by a down-regulation of TLR4 gene transcription. Additionally, the presence of an IEC-specific represso...

background to treat viral infection of chronic hepatitis c (chc) is a main strategy to prevent progression of liver disease, and cancer. some patients with chc have failed to respond to the common antiviral therapy in different populations. objectives in the current study it was aimed to find out the possible role of multiple drug resistance gene1 (mdr1) in non-responder patients with chc infec...

BACKGROUND The latest data released to the public from the Chinese Ministry of Health reported 120,940 confirmed H1N1 cases and 659 deaths on the Chinese mainland. OBJECTIVE We performed a prospective, single-center study to investigate the efficacy of lung recruitment maneuver (RM) with high-level positive end-expiratory pressure (PEEP) in patients with the 2009 influenza A (H1N1)-associated...

In autoimmune polyglandular syndromes (APS), several organ-specific autoimmune diseases are clustered. Although APS type I is caused by loss of central tolerance, the etiology of APS type II (APS-II) is currently unknown. However, in several murine models, depletion of CD4(+) CD25(+) regulatory T cells (T(regs)) causes a syndrome resembling human APS-II with multiple endocrinopathies. Therefore...

INTRODUCTION Hepatitis C virus (HCV), which is a major cause of liver diseases worldwide, undergoes genetic variation during the course of infection. The aim of this study was to examine sequence variations within the HVR1 region of HCV genotype 4 in infected Saudi patients treated with a combination therapy of interferon-α and ribavirin. METHODOLOGY cDNA of the HVR1 region of HVC-4 from one ...

The ability of murine helper T cells primed to the antigen, sheep erythrocytes (SRBC) to cross-react with burro erythrocytes (BRBC) in the in vitro anti-trinitrophenol (TNP) response to TNP-RBC was shown to be under genetic control. Although non-H-2 genes were shown to influence the absolute level of helper activity assayed after SRBC priming, the extent of cross-reaction of SRBC-primed helpers...
