The title compound, [Rh(C(5)H(7)O(2))(C(20)H(32)NP)(CO)], features an acetyl-acetonate-chelated Rh(I) cation coordinated by one P [Rh-P = 2.2525 (7) Å], one carbonyl C [Rh-C = 1.792 (3) Å] and two O [Rh-O = 2.0582 (17) and 2.0912 (18) Å] atoms in a slightly distorted square-planar geometry. Mol-ecules are packed in positions of least steric hindrance, with the phosphane ligands positioned above...

Billingham et al.' reported that mice and chickens injected as embryos with cells from other strains acquired a persistent tolerance to later skin grafts from the donor strains. It seemed possible to us that a similar, but naturally acquired, tolerance might be in part responsible for the variation in response of Rh-negative persons exposed to the Rh antigens.2 The hypothesis to be tested was t...

Phenacoccus solenopsis, the cotton mealy bug, has emerged as a serious pest of cotton in india, necessitating basic studies on its development and survival at different temperatures (20, 25, 30 and 35 °C) and relative humidities (rH) (65, 75 and 85 ± 1 %) levels to ascertain optimal population growth. a life table was constructed using temperature and humidity. The nymphal duration was 20.2 d a...

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 ...

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...

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...
