Taken together, these data demonstrated that induction of autophagy could represent a defense mechanism against apoptosis in human prostate cancer cells.”
“Single crystalline p-type K-doped ZnO nanorods (NR) have been synthesized by convenient and low-cost solution technique. X-ray diffraction analysis confirmed the hexagonal system of K-doped ZnO nanorods and a preferred a axis orientation. The diameter and length were found to be 30-50 nm and 150-200 nm, respectively, Luminespib manufacturer in electron microscopic studies. The

p-type nature and high hole density of 2.36 x 10(19) per cm(3) was demonstrated by Hall studies. A sharp lower cutoff and reduction in the bandgap was observed in UV-Vis study which is linked to its smaller size and p-type conduction in NR. In Photoluminescence click here studies, a near band emission in the UV range and a yellow emission with a blueshift were detected

in the visible region in K-doped ZnO NR. The variation in intensity of peaks is correlated with the dimensions of NR. The redshift observed in Raman peaks is explained in terms of the stress developed in ZnO nanostructure due to lattice mismatch by K doping. These results provide better insight of K-doped ZnO nanostructures for both fundamental research and technological applications in optoelectronic devices. (C) 2011 American Institute of Physics.

“New hydroxytelechelic cis-1,4-oligoisoprenes exhibiting variable values and distributions of the hydroxyl functionality were successfully prepared. The synthesis reactions involved chemical modifications of carbonyl telechelic cis-1,4-polyisoprene, which was obtained by controlled degradation of synthetic or natural rubber. These new oligomers were reacted with toluene diisocyanate to elaborate crosslinked polyurethane elastomers. The thermomechanical

properties of the prepared polyurethanes were investigated. The results show a strong relationship between the chemical structures and properties. This work mainly shows the potentiality of making new crosslinking polyurethane materials with controlled and various MEK162 order properties from natural rubber, a renewable resource.

“This studay is to construct a lentiviral vector harbouring an RNA interference (RNAi) sequence that targets the gene encoding the human high-mobility group nucleosomal binding protein 1 (NSBP1); to study its role in inducing G(2)/M phase arrest and apoptosis in prostate cancer (PCa) DU145 cells; and to assess the effect of its knockdown on cell proliferation in vitro and in vivo. RNAi was applied to knock down NSBP1 expression in the PCa cell line DU145 by lentiviral plasmids producing an NSBP1 small hairpin RNA. After NSBP1 knockdown in DU145 cells, the growth rate of cells was analyzed by MTT, and G(2)/M cell cycle arrest and apoptosis were assessed using a FAC-Scalibur flow cytometer. Tumour growth was assessed in nude mice.
