The Merrifield solid-phase peptide synthesis technique has been adapted to the synthesis of homo- and heterometallic metal−organic complex arrays (MOCAs). A terpyridine-appended and Fmoc-protected L-tyrosine derivative was metalated with Pt(II), Rh(III), or Ru(II) ions in solution and sequentially coupled at the surface of functionalized polymeric resin to give a metal complex triad (Rh−Pt−Ru),...

1. The theory of six allelic genes is reviewed, using the new improved nomenclature, and data are summarized regarding the distributions of the eight Rh types among white and negro individuals in New York City. 2. Results are presented of tests for property Hr in a series of 239 white individuals and 49 negroes. Statistical analysis of these data yields results supporting Race and Taylor's hypo...

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 ...

Risk homeostasis (RH) is a risk management theory espoused by Wilde (1994 & 2001) that claims that individuals adjust their risk-taking behaviour towards their target level of perceived risk. This paper claims that this phenomenon exists within the domain of information security. A future research approach is suggested that will confirm the existence of RH and also measure the extent of its imp...

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...
