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 clinically important Rh blood group system is complex, consisting of multiple distinct antigens. Despite clinical recognition for over 50 years, the Rh blood group antigens have remained poorly understood on a molecular level until the recent identification and characterization of the "Rh polypeptides," the core structural proteins of the Rh antigens. This group of erythrocyte membrane prot...

It is well known that Rh antibodies develop in persons who are nearly always Rh-negative, either as a result of immunization during pregnancy, or as a result of repeated transfusions when Rh-positive cells are given to Rh-negative recipients. During the last two and a half years we have had an opportunity to study 885 families in which the mothers were immunized by pregnancy. Nearly all these c...

Soil temperature and moisture are widely-recognized controlling factors on heterotrophic soil respiration (Rh), although they often explain only a portion of Rh variability. How other soil physicochemical and microbial properties may contribute to Rh variability has been less studied. We conducted field measurements on Rh half-monthly and associated soil properties monthly for two years in four...

The utility of two Rh(III) diimine complexes, Rh(phen)3 and Rh(phi)2(phen) (phen ) 1,10-phenanthroline, phi ) 9,10-phenanthrenequinone diimine), as sensitizers for the interconversion of norbornadiene (N) and quadricyclane (Q) has been investigated using steady-state photochemical and laser flash photolysis (LFP) techniques. Irradiation of acetonitrile solutions of Rh(phen)3 and N causes slow c...

The reaction of [Rh(μ-SH)(CO)(PPh(3))](2) or [Rh(μ-SH){P(OPh)(3)}(2)](2) with [Cp*MCl(2)](2) (M = Rh, Ir) in the presence of NEt(3) afforded the Rh(3) and IrRh(2) sulfido-bridged compounds [Cp*M(μ(3)-S)(2)Rh(2)(CO)(2)(PPh(3))(2)] (M = Rh, 1; Ir, 2) and [Cp*Rh(μ(3)-S)(2)Rh(2){P(OPh)(3)}(4)] (3). The reaction with [MCl(2)(cod)] (M = Pd, Pt), cis-[PtCl(2)(PPh(3))(2)] or [(η(6)-C(6)H(6))RuCl(2)](2)...

A series of dinuclear Rh(II) complexes, [Rh(2)(μ-OAc)(4)(H(2)O)(2)] (HOAc = acetic acid) (1), [Rh(2)(μ-gly)(4)(H(2)O)(2)] (Hgly = glycolic acid) (2), [Rh(2)(μ-CF(3)CO(2))(4)(acetone)(2)] (3), and [Rh(2)(bpy)(2)(μ-OAc)(2)(OAc)(2)] (4), were found to serve as H(2)-evolving catalysts in a three-component system consisting of tris(2,2'-bipyridine)ruthenium(II) (Ru(bpy)(3)(2+)), methylviologen (MV(2...

By CARROLL L. SPURLING, M.D. , MILTON S. SACKS, M.D. , AND ELSA F. JAHN, B.S. W ITH clarification of the pathogenesis of erythroblastosis fetalis it became evident that ideal therapy should be directed either at preventing the formation of maternal Rh antibodies, or, if already present, their passage into the fetal circulation in harmful amounts. Early therapeutic attempts with these goals in m...

[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...
