“Epitaxial La2NiMnO6 films were grown on (100)-oriented SrTiO3 and (LaAlO3)(0.3)-(SrAl0.5Ta0.5O3)(0.7) (LSAT) substrates under various growth conditions by pulsed laser deposition. Ferromagnetism and transport properties of B-site-ordered perovskite are greatly influenced by growth conditions. Optimum growth conditions of epitaxial La2NiMnO6 films, which exhibit the ferromagnetism similar to bulk properties,

are different for SrTiO3 and LSAT substrates probably due to the difference in surface migration. Since the initial stage of epitaxial growth might vary with the type of substrates, the ordering of Ni and Mn ions is different. Therefore, the ferromagnetism of La2NiMnO6 depends on the epitaxial growth conditions and type of substrates. (C) 2011 American Institute of Physics. [doi:10.1063/1.3641982]“
“This retrospective cohort study from click here a single clinical practice enrolled patients with evidence of calcified Peyronie’s disease (PD) plaques detected on penile ultrasound

at the time of initial presentation. The primary objective was to describe the effect of pentoxifylline (PTX) treatment on subtunical calcifications in men with PD. A PD-specific questionnaire was administered and sonographic ARN-509 evaluations were performed at baseline and follow-up visits. Descriptive statistics and chi(2) analysis were used to characterize the effect of PTX on calcified tunical plaques. In all, 71 men (mean age: 51.9 years) with PD and sonographic evidence of calcification were identified. Of them, 62 of these men were treated with PTX for a mean duration of 1 year, and nine with vitamin E or no treatment. Improvement or stabilization in calcium burden at follow-up was noted in 57 (91.9%) of men treated with PTX versus four (44.4%) of those not treated with PTX (P < 0.001). PTX users were much less likely to have a subjective worsening of their clinical condition (25.0% versus 78.3%, P=0.002). Treatment with PTX appeared to stabilize or reduce calcium content in PD plaques. A randomized controlled Alvocidib cell line trial is warranted to further explore this effect.

“Heat stress transcription factors (Hsfs) are the central regulators of defense response to heat stress. We identified a total of 25 rice Hsf genes by genome-wide analysis of rice (Oryza sativa L.) genome, including the subspecies of O. japonica and O. indica. Proteins encoded by OsHsfs were divided into three classes according to their structures. Digital Northern analysis showed that OsHsfs were expressed constitutively. The expressions of these OsHsfs in response to heat stress and oxidative stress differed among the members of the gene family. Promoter analysis identified a number of stress-related cis-elements in the promoter regions of these OsHsfs. No significant correlation, however, was found between the heat-shock responses of genes and their cis-elements.
