In the title compound, C(20)H(21)BrN(2)O(2), the bromo-phenyl ring is twisted by 40.13 (8)° from the benzimidazole mean plane and the Br atom deviates by 0.753 (1) Å from that plane. The sec-butyl group is disordered over two conformations in a 0.898 (5):0.102 (5) ratio. In the crystal, mol-ecules related by translation along [[Formula: see text]10] are linked into chains via weak C-H⋯Br hydrog...

The asymmetric unit of the title compound, C(10)H(8)BrNO(2), contains three crystallographically independent mol-ecules. Two of the N-C-C-Br side chains adopt anti conformations [torsion angles = -179.8 (5) and -179.4 (4)°] and the other is gauche [-66.5 (6)°]. The crystal structure features short Br⋯O [3.162 (5) Å] contacts, C-H⋯O hydrogen bonds and numerous π-π stacking inter-actions [centroi...

A step-scan Fourier-transform infrared spectrometer coupled with a multipass absorption cell was utilized to monitor the gaseous transient species benzoyl radical, C(6)H(5)CO. C(6)H(5)CO was produced either from photolysis of acetophenone, C(6)H(5)C(O)CH(3), at 248 nm or in reactions of phenyl radical (C(6)H(5)) with CO; C(6)H(5) was produced on photolysis of C(6)H(5)Br at 248 nm. One intense b...

BACKGROUND Chronic fluid overload due to overestimation of dry weight (DW) is the major factor in the development of hypertension in hemodialysis (HD) patients. The present study was undertaken to investigate whether bioimpedance ratio in the calf (Calf-BR = impedance at 200 kHz/impedance at 5 kHz) could be a useful hydration marker for estimation of DW and facilitate better control of blood pr...

Y-box-binding protein 1 (YB1) is a multifunctional transcription factor with vital roles in proliferation, differentiation and apoptosis. In this study, we have examined the role of its C-terminal domain (YB1 CTD) in proliferation, angiogenesis and tumorigenicity in breast cancer. Breast cancer cell line SK-BR-3 was infected with GFP-tagged YB1 CTD adenovirus expression vector. An 3-(4,5-dimeth...

The title compound, [CuBr(C(9)H(9)N(5))](n), has been prepared by the solvothermal treatment of CuBr with 3-(2-allyl-2H-tetra-zol-5-yl)pyridine. It is a new homometallic Cu(I) olefin coord-ination polymer in which the Cu(I) atoms are linked by the 3-(2-allyl-2H-tetra-zol-5-yl)pyridine ligands and bonded to one terminal Br atom each. The organic ligand acts as a bidentate ligand connecting two n...

We report the detection of an unstable intermediate generated during Br oxidation to Br3 in nitrobenzene by scanning electrochemical microscopy (SECM), and we attempt to simulate the collection of the intermediate using a proposed mechanism of Br oxidation to Br3 . At a distance of 3.5 mm between the tip and the substrate electrode in the SECM experiment, we observed two waves as we measured th...

Hetero-yellow (Hu red (RED) and brown (BR, high tannin) sorghums were fed dry-rolled or reconstituted (RED and BR only) to evaluate the effect of variety and reconstitution on the site and extent of starch and protein digestion in steers fitted with ruminal, duodenal and ileal cannulae. Processed grains were incorporated into 88% sorghum (DM basis) diets fed at 2% of body weight in a 5 • 5 Lati...

In the title compound, (C(7)H(11)N(2))(2)[SnBr(5)Cl], there is Br/Cl disorder in 0.6561 (12):0.3439 (12) and 0.8438 (12):0.1561 (12) ratios over two of three halide sites in the centrosymmetric anion, such that an overall formulation of [SnBr(5)Cl](2-) arises. In the crystal, associations of two cations and one anion linked by N-H⋯Br hydrogen bonds occur.

B romide (Br) causes positive interference with all clinical laboratory methods for the detenmination of serum Cl (1 .2). Interference with Cl measurement is much greater with ion-selective electrode (ISE) technology (1 .3) than with coubometry (1 -4). We recently described a patient ingesting therapeutic amounts of pynidostigmine Br (MestInon1 , containing 1 8.4 mg of Br [30.6%j per 60-mg tabl...
