The title structure, [Rh₂(C₁₁H₁₄NO)₄(C₇H₅N)₂], contains a dinuclear Rh complex of point symmetry -4 with an Rh-Rh unit and two benzonitrile ligands located in special positions along the twofold axis passing through -4. Four symmetry-equivalent mesitylacetamidate ligands bridge the Rh-Rh unit. Thus, each Rh(II) atom has an approximately octa-hedral coordination by one Rh [Rh-Rh = 2.4290 (6) Å],...

In this work, the effect of ethylene on flower opening of cut rose (Rosa hybrida) cv. Samantha was studied. However, although ethylene hastened the process of flower opening, 1-MCP (1-methylcyclopropene), an ethylene action inhibitor, impeded it. Ethylene promoted ethylene production in petals, but 1-MCP did not inhibit this process. Of the four ethylene biosynthetic genes tested, Rh-ACS1 and R...

The study of the interactions of double-stranded (ds) DNA with the dirhodium carboxylate compounds Rh(2)(O(2)CCH(3))(4)(H(2)O)(2) (Rh1), [Rh(2)(O(2)CCH(3))(2)(CH(3)CN)(6)](BF(4))(2) (Rh2), and Rh(2)(O(2)CCF(3))(4) (Rh3) supports the presence of covalently linked DNA adducts, including stable DNA interstrand cross-links. The present biochemical study refutes earlier claims that no reaction betwe...

It has been shown that the Rhesus (Rh) blood group antigens are encoded by two homologous genes: the Rh D gene and the Rh CcEe gene. The Rh CcEe gene encodes different peptides: the Rh C, c, E, and e polypeptides. Only one nucleotide difference has been found between the alleles encoding the Rh E and the Rh e antigen polypeptides. It is a C -+ G transition at nucleotide position 676, which lead...

1. Rh substances are found in amniotic fluid. Not all anti-Rh sera seem to be suitable for the detection of Rh substances in amniotic fluid. Careful selection of Rh antisera, as well as quantitative considerations, determine success or failure of their demonstration. 2. The baby's Rh type and not the mother's determines the occurrence of Rh substances in amniotic fluid. 3. There are Rh secretor...

The Rhesus (Rh) blood group system is one of the most complex systems. Over 46 different antigens have been serologically defined. Rh antigens are associated with the red cell membrane and are considered important fortheir integrity. The genes for Rh antigens are encoded together on the short arm of chromosome. One gene codes for Rh D antigen while the other gene encodes the polypeptide carryin...

background one of the most important cause of severe neonatal hyperbilirubinemia is hemolysis including rh incompatibility.  the aim of this study was to assess the rate of hyperbilirubinemia due to hemolysis in rh positive neonates  born to rh negative mothers. methods in this retrospective study from march 1998 to february 2003, 60 icteric rh positive newborns that were born to rh negative mo...

The expression ' typing of blood' has been applied loosely to determination of blood groups. It should not be so applied. One groups blood in determining 0, A, B and AB; types blood in determining M, N and MN; Rhesus groups blood in determining the Rh -fand Rh states; and Rhesus types (or Rh types) blood in determining R-h0, Rh', Rh", Rh'Rh", Rh15 Rh2, RhjRh2, and rh (using C-D-E system for a p...
