[Rh(CO)2Cl] 2 reacts with 1,3-diphenylcyclopentadienyl sodium or tetraphenylcyclopentadienyl sodium with formation of (l,3-P h2C5H3)Rh(CO ) 2 (1) or (C5HPh4)Rh(CO )2 (2), respectively. The reaction of 1 or 2 with PPh3 yields the corresponding carbonyl(cyclopentadienyl)(triphenylphosphane)rhodium complexes (l,3 -P h 2C5H3)Rh(CO)(PPh3) (3) or (C5HPh4)Rh(CO)(PPh3) (4). The 'H and ' C reported and ...

A cross sectional study among Al-Najaf province population related to blood group distribution showed that the ABO and Rh (D) blood groups distribution among 1628 young adult males 698 (42.9%) and females 930 (57.1%) from different locations in AlNajaf in Iraq. Blood samples were collected by venipuncture method. The blood was transferred into laboratory were tested for both the blood groups by...

Movement of the ligand/receptor complex in rhodopsin (Rh) has been traced. Bleaching of diazoketo rhodopsin (DK-Rh) containing 11-cis-3-diazo-4-oxo-retinal yields batho-, lumi-, meta-I-, and meta-II-Rh intermediates corresponding to those of native Rh but at lower temperatures. Photoaffinity labeling of DK-Rh and these bleaching intermediates shows that the ionone ring cross-links to tryptophan...

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 red cells of 63 members of 11 families were tested with (125)I-labeled anti-Rh(0)(D). Families with a history of hemolytic disease of the newborn due to fetomaternal Rh incompatibility were selected for study. In such families it was possible to determine the antibody binding to the Rh(0)(D) heterozygous red cells of the children and to compare within each family this value with the antibod...

The title compound, [Rh(2)(C(6)H(5)N(2)O(2))(2)(C(2)H(3)O)(2)I(2)(C(5)H(9)O(3)P)(2)], contains a binuclear centrosymmetric Rh(III) dimer bridged by iodide anions, with respective Rh⋯Rh and I⋯I distances of 4.1437 (5) and 3.9144 (5) Å. The Rh(III) atom is in a distorted octa-hedral RhCI(2)O(2)P coordination with considerably different Rh-I distances to the bridging iodide anions. There are no cl...

Among mountain species of Heptageniidae from Central Asia, six species belonging to the taxa Cinygmula McDunnough 1933, Himalogena Kluge 2004 and Caucasiron Kluge 1997 have all claws of the winged stages (subimago and imago) pointed. In this area Cinygmula is represented by two species: C. hutchinsoni (Traver 1939) (with pointed claws) and C. joosti Braasch 1977 (with the more typical ephemerop...

Antagonists of luteinizing hormone-releasing hormone (LH-RH), unlike the LH-RH agonists, suppress gonadotropins and sex steroid secretion immediately after administration, without initial stimulatory effects. [Ac-D-Nal(2)1,D-Ph(4Cl)2,D-Pal(3)3,D-Cit6,D-Ala10]LH-R H (SB-75; Cetrorelix) is a modern, potent antagonistic analog of LH-RH. In this study, the binding characteristics of receptors for L...

Because ascorbic acid (AA) is concentrated in synaptic vesicles containing glutamic acid, we hypothesized that AA might act as a neurotransmitter. Because AA is an antioxidant, it might therefore inhibit nitric oxidergic (NOergic) activation of luteinizing hormone-releasing hormone (LH-RH) release from medial basal hypothalamic explants by chemically reducing NO. Cell membrane depolarization in...
