Addition of Li, Na, K and Cs to a 1.5 wt% Rh/Al,O, catalyst resulted in a decrease of the hydrocarbon formation rate, while the methanol formation rate was almost unaffected. The overall result is an increased oxygenate selectivity at a decreased total activity. The oxo-selectivity increased in the order unpromoted < Li < Na< K < Cs. The results suggest that the main role of the alkali promoter...

Objective Anti-Rh D IgG is used for the prevention of anti-D antibody production in Rh- individuals who have been exposed to Rh+ red blood cells. The stability of IgG preparations as a solution is low, with a shelf life of a year or more. Formulation of anti-Rh D IgG as a lyophilized preparation would decrease its degradation rate and increases its shelf life. The objective of this study was t...

The RBC Rh antigens are of large clinical importance, but until recently have been poorly understood at a molecular level. The Rh polypeptides are a family of nonglycosylated Mr 30- to 32-Kd transmembrane proteins that are core structural components of the Rh antigens and have been purified and partially characterized biochemically. Rh polypeptides are present in RBCs from normal humans and oth...

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...

The rapid decrease of several stocks of Pacific herring, Clupea pallasi, in Puget Sound, Washington, has led to concerns about the effects of industrial and nonpoint source contamination on the embryo and larval stages of this and related forage fish species. To address these concerns, the state of Washington and several industries have funded efforts to develop embryo and larval bioassay proto...

The effects of temperature and infection by Ichthyophonus were examined in juvenile Pacific herring (Clupea pallasii) maintained under simulated overwinter fasting conditions. In addition to defining parameters for a herring bioenergetics model (discussed in Vollenweider et al. this issue), these experiments provided new insights into factors influencing the infectivity and virulence of the par...

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...
