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...

The spatial heterogeneity of stomatal closure in response to rapid desiccation of excised well-watered Tradescantia virginiana leaves grown at moderate (55%) or high (90%) relative air humidity (RH) was studied using a chlorophyll fluorescence imaging system under non-photorespiratory conditions. Following rapid desiccation, excised leaves grown at high RH had both a greater heterogeneity and a...

This paper examines the experiences of South East Queensland (SEQ) households concerning rainwater harvesting (RH). Although the adoption of household RH is currently booming after extended stagnation at around 8% in SEQ, what actually motivates this adoption is not well understood. This paper reports on the pilot study for my doctoral thesis, which has the three aims of (a) characterising hous...

Density functional theory has been used to investigate the mechanism and kinetics of the liquid-phase, oxidative carbonylation of toluene to p-toluic acid (C7H8 + CO + /2O2 f p-C7H6COOH + H2O) catalyzed by Rh(III) cations. In toluene solution containing trifluoroacetic acid and dissolved CO, Rh(III) is coordinated to three trifluoroacetate (TFA) anions and two CO molecules as Rh(CO)2(TFA)3. The...

Rabbit polyclonal antibodies were raised against synthetic peptides corresponding to hydrophilic regions of the human Rhesus (Rh) IX cDNA-encoded polypeptide predicted to be extracellularly or intracellularly exposed in the topologic model of the Rh blood group protein. Four antibodies encompassing residues 33-45 (MPC1), 224-233 (MPC4), 390-404 (MPC6), and 408-416 (MPC8) were characterized and ...

Recent studies show that antagonists of growth hormone-releasing hormone (GH-RH) inhibit proliferation of various cancers indirectly through blockage of the endocrine GH-insulin-like growth factor (IGF) I axis and directly by an action on tumor cells involving the suppression of autocrine/paracrine IGF-I, IGF-II, or GH-RH. The effectiveness of therapy with GH-RH antagonist JV-1-38 and its mecha...
