The magnetic character of Rh and Ru on the surface of Au and Ag is investigated by means of weak localization ~WL! and the anomalous Hall effect ~AHE!. Dephasing of the conduction electrons in WL is the most sensitive method to detect magnetic surface impurities. The Au/Rh and Au/Ru systems are investigated in the range between 1/100 of a monolayer of Rh ~Ru! and several monolayers of Rh ~Ru!. ...

A sensitive and specific double antibody radioimmunoassay has been developed capable of measuring LH-RH in extracted human plasma. Thyrotropin releasing hormone, lysine vasopressin and most of LH-RH analogues did not appear to affect the assay. Hypothalamic extract and some of the LH-RH analogues produced displacement curves which were parallel to that obtained with the synthetic LH-RH. Sensiti...

BACKGROUND/AIMS The pathophysiologic mechanism of rectal hyposensitivity (RH) is not well documented, and the significance of RH in biofeedback therapy (BFT) has not been evaluated. Thus, we aimed to assess the effect of BFT in constipated patients according to the presence of RH. METHODS Five hundred and ninety constipated patients (238 males and 352 females) underwent anorectal physiologic ...

Human erythroleukemic K562 cells are known to have several erythroid properties. K562 cells possess Rh mRNAs, but expression of Rh proteins has not previously been reported. We immunoprecipitated Rh protein from K562 cell lysate using rabbit anti-Rh and detected Rh(D) antigens on K562 cells using fluorescence-activated cell sorting (FACS). These results suggest that K562 cells will be useful as...

RH genes are highly polymorphic and encode the most complex of the 35 human blood group systems. This genetic diversity contributes to Rh alloimmunization in patients with sickle cell anemia (SCA) and is not avoided by serologic Rh-matched red cell transfusions. Standard serologic testing does not distinguish variant Rh antigens. Single nucleotide polymorphism (SNP)-based DNA arrays detect many...

in this paper rationalized haar (rh) functions method is applied to approximate the numerical solution of the fractional volterra integro-differential equations (fvides). the fractional derivatives are described in caputo sense. the properties of rh functions are presented, and the operational matrix of the fractional integration together with the product operational matrix are used to reduce t...

Background and Aim: One of the main goals of blood transfusion medicine is to determine the compatibility of the blood products with the patients. Therefore, clinical and laboratory (serologic) evaluations should be done to determine the maximum compatibility (or minimum incompatibility). The most known blood groups is the ABO antigenic system and the most important of them is Rh system. Among ...

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 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...
