- The Breast Cancer Association Consortium (BCAC) has been established to conduct combined case-control analyses with augmented statistical power to try to confirm putative genetic associations with breast cancer. We genotyped nine SNPs for which there was some prior evidence of an association with breast cancer: CASP8 D302H (rs1045485), IGFBP3 -202 C --> A (rs2854744), SOD2 V16A (rs1799725), TGFB1 L10P (rs1982073), ATM S49C (rs1800054), ADH1B 3' UTR A --> G (rs1042026), CDKN1A S31R (rs1801270), ICAM5 V301I (rs1056538) and NUMA1 A794G (rs3750913). We included data from 9-15 studies, comprising 11,391-18,290 cases and 14,753-22,670 controls. We found evidence of an association with breast cancer for CASP8 D302H (with odds ratios (OR) of 0.89 (95% confidence interval (c.i.): 0.85-0.94) and 0.74 (95% c.i.: 0.62-0.87) for heterozygotes and rare homozygotes, respectively, compared with common homozygotes; P(trend) = 1.1 x 10(-7)) and weaker evidence for TGFB1 L10P (OR = 1.07 (95% c.i.: 1.02-1.13) and 1.16 (95% c.i.: 1.08-1.25), respectively; P(trend) = 2.8 x 10(-5)). These results demonstrate that common breast cancer susceptibility alleles with small effects on risk can be identified, given sufficiently powerful studies.

- Using three different laser systems, we demonstrate a convenient and simple plasma based diagnostic of the contrast of high-power short-pulse lasers. The technique is based on measuring the specular reflectivity from a solid target. The reflectivity remains high even at relativistic intensities above 10(19) W/cm(2) in the case of a high-contrast prepulse-free laser. On the contrary, the specular reflectivity drops with increasing intensities in the case of systems with insufficient contrast due to beam breakup and increased absorption caused by preplasma.

- Titanium dioxide solution was prepared via sol-gel process with and without acetyl acetone (AcAc). The formation of the anatase phase in the thin films using AcAc was initiated at 300 degrees C while the anatase phase in the thin films without using AcAc began to appear at 100 degrees C. Surface roughness of the TiO2 films using and without using AcAc ranged from 0.414 to 3.08 nm and from 3.72 to 5.35 nm, respectively. Photocatalytic decomposition rate examined by methylene blue solution showed 80% at 400 degrees C and 88% at 600 degrees C for the TiO2 thin films using AcAc. On the other hand, the photocatalytic decomposition rate of the TiO2 thin films without using AcAc showed 80% at 100 degrees C and 97% at 400 degrees C, respectively. At the temperature above 400 degrees C, the photocatalytic activity decreased due to appearance of the rutile phase. Comparison between the TiO2 thin films showing the maximum photocatalytic activity revealed that the TiO2 thin film without using AcAc showed 10% higher photocatalytic decomposition rate from the initial 10 to 120 min as compared with the TiO2 thin film using AcAc, which was closely related to the formation of the anatase phase and the surface roughness.
