We consider an optimization problem of the form min xQx+ cx s.t. ‖x− μh‖ ≤ rh, h ∈ S, ‖x− μh‖ ≥ rh, h ∈ K, x ∈ P, where P ⊆ R is a polyhedron defined by m inequalities and Q is general and the μh ∈ R and the rh quantities are given; a strongly NP-hard problem. In the case |S| = 1, |K| = 0 and m = 0 one obtains the classical trust-region subproblem which is polynomially solvable, and has been th...

In the title compound, [Rh(C(5)H(7)O(2)){C(12)H(17)P(C(6)H(11))(2)}(CO)], the Rh(I) atom is coordinated by one carbonyl C, one P and two O atoms, forming a slighlty distorted square-planar configuration.

A two-point binding mechanism for the cationic rhodium(I)-catalyzed carbonyl-directed catalytic asymmetric hydroboration of a cyclic γ,δ-unsaturated amide is investigated using density functional theory. Geometry optimizations and harmonic frequency calculations for the model reaction are carried out using the basis set 6-31+G** for C, O, P, B, N, and H and LANL2DZ for Rh atoms. The Gibbs free ...

The authors obtained two mouse monoclonal antibodies, G-208 and G-166, to recombinant human interferon-gamma (rH-IFN-gamma). Immunologically, they were classified as IgG1-K subclass. G-208 neutralized the antiviral activity of natural and recombinant human IFN-gamma, but did not bind to heat-denatured rH-IFN-gamma. G-166 was able to bind to rH-IFN-gamma as well as to heat-denatured rH-IFN-gamma...

There are two major theories for inheritance of Rh blood group system: Fisher - Race theory and Wiener theory. Aim of this study was identifying frequency of RHDCE alleles in Bosnian - Herzegovinian population and introduction of this method in screening for Rh phenotype in B&H since this type of analysis was not used for blood typing in B&H before. Rh blood group was typed by Polymerase Chain ...

the aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable h+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. drug resin complexes (drc) were prepared and evaluated for the percentage of moisture gain when placed in a humidity chamber at 40e2 °...

Ligand pharmacology of histamine H(3)-receptors is species-dependent. In previous studies, two amino acids in transmembrane domain 3 (TM III) were shown to play a significant role. In this study, we characterized human and rat histamine H(3)-receptors (hH(3)R and rH(3)R, respectively), co-expressed with mammalian G proteins in Sf9 insect cell membranes. We compared a series of imidazole-contain...

BACKGROUND The immunosuppressive protein glycodelin A (GdA) is secreted by a large number of gynaecological tumors. GdA has a unique glycosylation, including fucosylated LacdiNAc structures. Trophoblast tumor cells produce a variety of steroid hormones and human chorionic gonadotropin (hCG). The purpose of this study was to investigate the effect of GdA N-glycans on hCG, cortisol, estradiol and...

The survival of Salmonella on dried chamomile flowers, peppermint leaves, and green tea leaves stored under different conditions was examined. Survival and growth of Salmonella was also assessed after subsequent brewing using dried inoculated teas. A Salmonella enterica serovar cocktail was inoculated onto different dried tea leaves or flowers to give starting populations of approximately 10 lo...

The chemical oxidation of rhodium(i) complexes [Rh(L)(COD)][BF4], where L is a ferrocenyl phosphine/N-heterocyclic carbene ligand, with 2 equiv. triaryl-aminium salt [(4-BrC6H4)3N][BF4] in acetonitrile gave planar chiral, air-stable [Rh(L–H)(MeCN)3][BF4]2 the ferrocene (C5H4CH2ImR or C5H4CH2BImCH2Mes) ring has been C–H activated at position good to excellent yields. An important reactivity diff...
