The dihydrido germyl complex cis,fac-[Rh(GePh3)(H)2(PEt3)3] (2) was synthesized by an oxidative addition of HGePh3 at [Rh(H)(PEt3)3] (1). Treatment of 2 with neohexene generated the rhodium(i) germyl complex [Rh(GePh3)(PEt3)3] (3). Alternatively, treatment of the methyl complex [Rh(CH3)(PEt3)3] (4) with HGePh3 furnished at room temperature also 3. Low-temperature NMR measurements revealed an in...

Background One of the most important cause of severe neonatal hyperbilirubinemia is hemolysis including Rh incompatibility.  The aim of this study was to assess the rate of hyperbilirubinemia due to hemolysis in Rh positive neonates  born to Rh negative mothers. Methods In this retrospective study from March 1998 to February 2003, 60 icteric Rh positive newborns that were born to Rh negative m...

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...

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...

Human monoclonal antibodies (MoAbs) directed against the blood group Rh(D), (c), and (E) antigens produced by Epstein-Barr virus (EBV)-transformed lymphoblastoid cell lines have been used to characterize the Rh components of human red cell membranes and to determine whether the Rh(D), (c), and (E) epitopes are carried by distinct polypeptides. After immunoprecipitation with the anti-Rh(D) antib...

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...

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...

The reaction of [Rh(μ-SH)(CO)(PPh(3))](2) or [Rh(μ-SH){P(OPh)(3)}(2)](2) with [Cp*MCl(2)](2) (M = Rh, Ir) in the presence of NEt(3) afforded the Rh(3) and IrRh(2) sulfido-bridged compounds [Cp*M(μ(3)-S)(2)Rh(2)(CO)(2)(PPh(3))(2)] (M = Rh, 1; Ir, 2) and [Cp*Rh(μ(3)-S)(2)Rh(2){P(OPh)(3)}(4)] (3). The reaction with [MCl(2)(cod)] (M = Pd, Pt), cis-[PtCl(2)(PPh(3))(2)] or [(η(6)-C(6)H(6))RuCl(2)](2)...
