In the crystal structure of the title compound, [HgBr(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) cation is located on an inversion center and is coordinated by two N atoms from the pyrazine rings and four bridging Br(-) anions in a distorted octa-hedral geometry. The Br(-) anions bridge the Hg(II) cations with significantly different Hg-Br bond distances of 2.4775 (8) and 3.1122 (8) Å, forming polyme...

In the title coordination polymer, [CdBr(2)(C(8)H(8)N(2)S(2))](n), the Cd(II) atom is six-coordinated in a distorted octa-hedral geometry by two N atoms from a 2,2'-dimethyl-4,4'-bi-1,3-thia-zole ligand and four bridging Br atoms. The bridging function of the Br atoms leads to a chain structure along [100]. Inter-chain C-H⋯Br hydrogen bonds and π-π contacts between the thia-zole rings [centroid...

A reduction in lower limb cross-sectional area (CSA) occurs after bed rest (BR). This should lead to an equivalent reduction in maximal instantaneous muscular power (W(p)) if the body segments' lengths remain unchanged. W(p) was determined during maximal jumps off both feet on a force platform before and on days 2, 6, 10, 32, and 48 after a 42-day duration BR. CSA of thigh muscles was measured ...

The pharmacological profile of BR-A-657, 2-n-butyl-5-dimethylamino-thiocarbonyl-methyl-6-methyl-3-{[2-(1H-tetrazole-5-yl)biphenyl-4-yl]methyl}-pyrimidin-4(3H)-one, a new nonpeptide AT1-selective angiotensin receptor antagonist, has been investigated in a variety of in vitro and in vivo experimental models. In the present study, BR-A-657 displaced [(125)I][Sar(1)-Ile(8)]angiotensin II (Ang II) f...

This work reports the theoretical study carried out with M06-2x functional and aug-cc-pVTZ basis set of four ammonium two phosphonium salts, Me3NH+Cl–, Me3NH+Br–, Me4N+Cl–, Me4N+Br–, Me4P+Cl– Me4P+Br–. The structure monomeric dimeric complexes (between 1 5 conformations each) has been analyzed in what concern geometries, energies NH+ stretching frequencies. geometries were successfully compared...

The asymmetric unit of the title compound, (C(5)H(5)BrN)(2)[SnBr(6)], contains one cation and one half-anion. The [SnBr(6)](2-) anion is located on an inversion center and forms a quasi-regular octa-hedral arrangement. The crystal structure consists of two-dimensional supra-molecular layers assembled via hydrogen-bonding inter-actions of N-H⋯Br-Sn [D⋯A = 3.375 (13)-3.562 (13) Å and D-H⋯A = 127-...

Bacteriorhodopsin (BR) essentially free of native lipids has been prepared in a highly stable state. Purple membrane was solubilized in Triton X-100 and BR was purified by size exclusion chromatography using 3-[cholamidopropyl)dimethylammonio]-2-hydroxyl-1-propanesulfonic acid (CHAPSO) detergent at pH 5. Molar ratios of phospholipid/BR ranged from 0.4 to 0.05 corresponding to 94-98% phospholipi...

This study was designed to investigate the effects an 8-Br-cGMP on the neuronal activity of rat vestibular nuclear cells. Sprague-Dawley rats aged 14 to 16 days were decapitated under ether anesthesia. After treatment with pronase and thermolysin, the dissociated vestibular nuclear cells were transferred into a chamber on an inverted microscope. Spontaneous action potentials and potassium curre...

For decades, philosophers and psychologists have assumed that children understand other people's behavior on the basis of Belief Reasoning (BR) at latest by age 5 when they pass the false belief task. Furthermore, children's use of BR in the true belief task has been regarded as being ontogenetically prior. Recent findings from developmental studies challenge this view and indicate that 4to 5-y...
