This treatment effectively induced estrous cyclicity among anestrous cows, synchronized estrus activity, and prevented premature luteolysis with no negative effect on pregnancy.”
“In

this article, we describe the synthesis of two azobenzene and two stilbene-based diacetylene chromophores containing terminal electron-donating (OCH3) and electron-withdrawing (NO2) terminal HIF inhibitor groups with esterification reactions. The target compounds were characterized by NMR, X-ray diffraction (XRD), absorption, and photoluminescence spectroscopies. We investigated the structural effects of these photochromic compounds on the EZ photoisomerization and 1,4-addition under UV irradiation. 4-[(4-Nitrophenyl)-diazenyl]phenyl pentacosa-10,12-diynoate, Caspase activity assay incorporating the electron-withdrawing nitro group (NO2), underwent the fastest rate of Z-to-E isomerization in darkness via a rotation mechanism. Our results demonstrate that self-assembled azobenzene Z isomers exhibited enhanced fluorescence under UV irradiation. XRD spectroscopy identified bilayer packing by the polydiacetylene films after 1,4-addition. Chromophores comprising the diacetylene group presented moderate photochromic stability upon 1,4-addition, changing from their original yellowish

color to form a blue phase. These synthesized compounds may be useful in the development of new and unique functional materials that exhibit bistable photochromism. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“For sensitive detection of H-2, ZnO nanowires networks decorated with photo-decomposed Pd nano-particles were fabricated between femtosecond MX69 laser-writing interdigitated electrodes by chemical vapor deposition method. When H-2 concentration is increased from 20 to 4000 ppm at room temperature, sensitivity of the sample is increased from 3.7% to 1017.9%. The high sensitivity can be explained by considering

the reaction between the adsorbed O-2(-) and the disassociated H atoms facilitated by Pd nanoparticles. This mechanism is further supported by the H-2 response results under UV light illumination, which can reduce the amount of O-2(-) on the ZnO surface, leading to depressed sensitivity. The sensor also shows high selectivity, long-term stability, and ultra-low power consumption of nanowatt level, due to the novel fabrication process. (C) 2011 American Institute of Physics.

“Childhood onset of epilepsy has long been associated with an adverse impact on brain development and cognition. In this study it is proposed that earlier (vs later) onset of temporal lobe epilepsy (TLE) has a negative developmental impact on distant brain structures. One hundred ten patients with TLE were assigned to early 14 years, N=58) and late (>15 years, N=52) age at onset of epilepsy groups.
