Background: RhD antigen system is the leading cause of hemolytic disease of the fetus and newborn (HDFN). Paternal molecular RhD zygosity test is valuable to decide on the use of anti-D immunoglobulin prophylaxis in Rh D-negative pregnant women. We aimed to investigate the paternal RhD zygosity by two molecular methods among blood donors in Kurdistan province, the west of Iran. We also compared...

BACKGROUND Vicriviroc (VCV) is a CCR5 antagonist with nanomolar activity against human immunodeficiency virus (HIV) replication in vitro and in vivo. We report the results of a phase II dose-finding study of VCV plus dual nucleoside reverse-transcriptase inhibitors (NRTIs) in the treatment-naive HIV-1-infected subjects. METHODS This study was a randomized, double-blind, placebo-controlled tri...

  SUMMARY Hepatitis B Virus is one of the most important and common infections agent in the world and is prohably endemic in IRAN. In our study the 12 years prevalance (April 1981-December 1993) HBsAg and VDRL positive cases and their relationship with some epidemiologic factors such as sex, age, occupation among the blood donors of the Ramadan province (west of IRAN) have been considered. ...

BACKGROUND AND AIM Suboestrus constitutes the largest factor responsible for poor reproductive efficiency in buffaloes. Therefore, oestrus synchronization (OS) and fixed-time artificial insemination (AI) is considered an alternative approach to enhance reproductive efficiency in buffaloes. Thus, the present study was carried out to study the efficacy of modified Ovsynch protocol with fixed time...

The utility of two Rh(III) diimine complexes, Rh(phen)3 and Rh(phi)2(phen) (phen ) 1,10-phenanthroline, phi ) 9,10-phenanthrenequinone diimine), as sensitizers for the interconversion of norbornadiene (N) and quadricyclane (Q) has been investigated using steady-state photochemical and laser flash photolysis (LFP) techniques. Irradiation of acetonitrile solutions of Rh(phen)3 and N causes slow c...

Several researchers have shown that Pt-Rh bimetallic catalysts can perform synergistically for the NO/H2, NO/CO, CO/O2, and NO/CO/HC reactions [1-5]. Lakis and coworkers clarified some of the mystery surrounding the synergistic performance of Pt-Rh catalysts for the NO + H2 reaction by using analytical electron microscopy (AEM) to show that the synergistic performance of a Pt(95%)Rh(5%)/γ-Al2O3...

The influence of temperature and relative air humidity on the stability of ceftriaxone disodium (CTN) in Biotrakson and Tartriakson was investigated. At RH = 0%, the degradation of ceftriaxone was the first-order reaction, while at RH from 50.9% to 76.4% it was an autocatalytic first-order reaction relative to the substrate concentration. The influence of temperature on the stability of CTN was...

The clinically important Rh blood group system is complex, consisting of multiple distinct antigens. Despite clinical recognition for over 50 years, the Rh blood group antigens have remained poorly understood on a molecular level until the recent identification and characterization of the "Rh polypeptides," the core structural proteins of the Rh antigens. This group of erythrocyte membrane prot...

It is well known that Rh antibodies develop in persons who are nearly always Rh-negative, either as a result of immunization during pregnancy, or as a result of repeated transfusions when Rh-positive cells are given to Rh-negative recipients. During the last two and a half years we have had an opportunity to study 885 families in which the mothers were immunized by pregnancy. Nearly all these c...

Soil temperature and moisture are widely-recognized controlling factors on heterotrophic soil respiration (Rh), although they often explain only a portion of Rh variability. How other soil physicochemical and microbial properties may contribute to Rh variability has been less studied. We conducted field measurements on Rh half-monthly and associated soil properties monthly for two years in four...
