In a significant number of hormone-refractory patients, the AR is overexpressed, mutated or genomically amplified. These genetic alterations maintain an active presence for a highly sensitive AR, which is responsive to androgens, antiandrogens or nonandrogenic hormones and collectively confer a selective growth advantage to PCa cells. This review provides a brief synopsis of the AR structure, AR coregulators, posttranslational Epigenetic Reader Do inhibitor modifications of AR, duality of AR function in prostate epithelial and stromal cells, AR-dependent signaling, genetic changes in the form of somatic and germline mutations and their known functional significance in PCa cells and tissues.”
“Ultrahigh molecular

weight fibers were treated by low energy ion beam in a pulse regime. Results of infrared and WAXD analyses showed the change of both chemical structure and morphology of the fiber surface. Adhesion of the treated fiber surface to conventional binders appeared to be two times higher than that of untreated fiber. (C) 2011 Wiley Periodicals, Inc.

“Graphoepitaxial alignment of Au particles through solid-state dewetting

of gold films on substrates patterned with topographic features has been demonstrated. Gold films were dewetted on surfaces with a diperiodic array of pits with inverted pyramidal shapes. Under specific conditions, films dewet to form a periodic array of monodisperse particles in the pits. Thick films pull out of the pits rather than dewet into the pits. While particles that form on flat surfaces or between the pits have a (111) out-of-plane texture and random in-plane orientation, particles in pits have (100) out-of plane texture and in-plane alignments such that Au (111) planes are parallel with the facets of the pits. Requirements for relative geometric characteristics of the pits and the film thickness, and requirements

on surface-energy anisotropy, are defined for formation of monodisperse graphoepitaxially-aligned particles. (C) 2011 American MAPK inhibitor Institute of Physics. [doi:10.1063/1.3567302]“
“Aromatic polyamides and polythioamides with pendent chlorobenzylidine rings were synthesized through direct polycondenzation of 2-(p-chlorobenzalimino) terephthalic acid with the diamines 4,4′-oxidianiline (1a), 4,4′-methylenediamide (1b), 4,4′-diaminodiphenyl sulfone (1c), and thioamines 4,4′-(bisthiourea) diphenyl ether (3a), 4,4′-(bisthiourea) diphenyl methane (3b), 4,4′-(bisthiourea) diphenyl sulfone (3c), respectively, in DMF using P(OPh)(3)/pyridine. The polymers were precipitated using water as nonsolvent. FTIR and H-1-NMR spectroscopic analysis was used to characterize the monomers and polymers. Representative polyamides and polythioamides were used for the removal of heavy metal ions such as Pb(II), Cd(II), Cu(II), and Cr(III) from aqueous solutions.
