The variation in the resistivity was in a narrow range (14%) over a Si wafer. The TEM imaging revealed that the Al substituted

nanowire had a bamboo-like structure with grains larger than 1.6 mu m. The electromigration activation energy was 0.72 eV, which is comparable to that of a pure Al wire with a bamboo-like structure. The product of the critical current density and wire length was 1.3 x 10(3) A/cm at 250 degrees C; 2.1 times higher than that of a pure Al wire with a polycrystalline structure. The acceleration of electromigration due to current density was 2.0, indicating that incubation time dominates electromigration lifetime. The prolonged incubation time observed in the electromigration test is attributed to the reduction in electromigration-induced mass transport due to the microstructure of the Al substituted nanowire. Even the formation of a small Selleck Bucladesine void immediately after incubation may be a fatal defect for nanoscale Al wires. (C) 2011 American Institute of Physics. [doi:10.1063/1.3601345]“
“We examined a possible relationship -420C>G SNP of the resistin gene with plasma resistin and C-reactive protein concentrations in intracerebral hemorrhage. Three hundred

and forty-four Chinese Han patients with intracerebral hemorrhage and 344 age- and gender-matched healthy controls were included in our study. Plasma resistin and C-reactive concentrations were measured and SNP -420C>G was genotyped. The genotype frequencies in controls and patients were not significantly different (P = 0.672). Plasma resistin and C-reactive protein levels were significantly different between the SNP -420C>G genotypes, even after adjustment GSK1210151A for age, gender and body mass index. The common homozygote (C-C) had the lowest resistin and C-reactive protein plasma concentrations; the

plasma resistin and C-reactive protein concentrations in the heterozygote (C-G) and the rare allele homozygote (G-G) did not differ significantly. Plasma resistin levels were significantly associated with plasma C-reactive protein level. We conclude that SNP -420C>G of the resistin Adriamycin DNA Damage inhibitor gene could be involved in the inflammatory component of intracerebral hemorrhage through enhanced production of resistin.”
“For selected indications, coronary computed tomographic (CT) angiography is an established clinical technology for evaluation in patients suspected of having or known to have coronary artery disease. In coronary CT angiography, image quality is highly dependent on heart rate, with heart rate reduction to less than 60 beats per minute being important for both image quality and radiation dose reduction, especially when single-source CT scanners are used. beta-Blockers are the first-line option for short-term reduction of heart rate prior to coronary CT angiography. In recent years, multiple beta-blocker administration protocols with oral and/or intravenous application have been proposed.
