A poly(vinyl chloride) matrix membrane sensor for the selective determination of thiocyanate has been developed based on the use of copper(II)-2-(5-bromo-2-pyridylazo)-5-diethylaminophenol complex (Cu-PADAP) as a novel charged carrier, and o-nitrophenyloctyl ether (o-NPOE) as a solvent mediator. The sensor displays a significantly enhanced response towards SCN(-) ions over the concentration ran...

Electrolyzed-reduced water (ERW) scavenges reactive oxygen species and is a powerful anti-oxidant. A positive correlation between oxidative stress and aging has been proved in many model organisms. In Caenorhabditis elegans, many long-lived mutants showed reduced fertility as a trade off against longevity phenotype. We aimed to study the eff ect of ERW on oxidative stress, fertility and lifespa...

In a previous study, we found that 2-deoxyribonolactone is effectively generated in the specific 5-bromouracil ((Br)U)-substituted sequence 5'-(G/C)[A]n = 1,2 (Br)U(Br)U-3' and proposed that a formed uracil-5-yl radical mainly abstracts the C1' hydrogen from the 5'-side of (Br)U(Br)U under 302-nm irradiation condition. In the present work, we performed photoirradiation of (Br)U-substituted DNA ...

In the title salt, [C(6)H(5)N(CH(3))(3)][Sn(2)Br(5)(C(7)H(6)Br)(4)], the Sn(IV) atoms of the dinuclear anion are bridged by a Br atom; the Sn-Br(bridge) bond lengths are 2.9818 (5) and 3.0470 (5) Å. Both Sn atoms show a distorted cis-trigonal-bipyramidal coordination geometry that is distorted towards a square pyramid. In the crystal, weak C-H⋯π inter-actions occur between anions and cations.

Noscapine, a microtubule-interfering agent, has been shown to arrest mitosis, to induce apoptosis, and to have potent antitumor activity. We report herein that two brominated derivatives of noscapine, 5-bromonoscapine (5-Br-nosc) and reduced 5-bromonoscapine (Rd 5-Br-nosc), have higher tubulin binding activity than noscapine and affect tubulin polymerization differently from noscapine. In addit...

The title compound PBPEA, C(10)H(7)Br(5)O(2), has its ethyl acetate portion nearly orthogonal to the benzene ring, with a C-C-C-C torsion angle of 88.3 (5)°. The packing involves an inter-molecular contact with a Br⋯Br distance of 3.491 (1) Å, having C-Br⋯Br angles of 173.4 (2) and 106.0 (2)°. The crystal studied was an inversion twin.

In the crystal structure of the title compound, C(5)H(5)BrN(2), mol-ecules assemble via pairs of N-H⋯N hydrogen bonds into inversion dimers using only the syn H atom on the amine group. These dimers then assemble further into two-dimensional layers via type I C-Br⋯Br [Br⋯Br = 3.693 (s6) Å] halogen bonding along the (102) plane.

We have shown previously that treadmill exercise within lower body negative pressure (LBNPex) maintains upright exercise capacity (peak oxygen consumption, Vo(2peak)) in men after 5, 15, and 30 days of bed rest (BR). We hypothesized that LBNPex protects treadmill Vo(2peak) and sprint speed in women during a 30-day BR. Seven sets of female monozygous twins volunteered to participate. Within each...

Reaction of lutidine-bridged dibenzimidazolium dibromides 1 – 4 with palladium acetate gives pincer-type palladium complexes of the type [Pd(L)Br]Br [5]Br–[8]Br. Crystals suitable for an X-ray diffraction study have been obtained by slow evaporation of the solvent from dichloromethane/methanol solutions of [7]Br and [8]Br. The crystal structure of [7]+ reveals a pincer topology of the cationic ...
