- A locus at 19p13 is associated with breast cancer (BC) and ovarian cancer (OC) risk. Here we analyse 438 SNPs in this region in 46,451 BC and 15,438 OC cases, 15,252 BRCA1 mutation carriers and 73,444 controls and identify 13 candidate causal SNPs associated with serous OC (P=9.2 × 10-20), ER-negative BC (P=1.1 × 10-13), BRCA1-associated BC (P=7.7 × 10-16) and triple negative BC (P-diff=2 × 10-5). Genotype-gene expression associations are identified for candidate target genes ANKLE1 (P=2 × 10-3) and ABHD8 (P<2 × 10-3). Chromosome conformation capture identifies interactions between four candidate SNPs and ABHD8, and luciferase assays indicate six risk alleles increased transactivation of the ADHD8 promoter. Targeted deletion of a region containing risk SNP rs56069439 in a putative enhancer induces ANKLE1 downregulation; and mRNA stability assays indicate functional effects for an ANKLE1 3′-UTR SNP. Altogether, these data suggest that multiple SNPs at 19p13 regulate ABHD8 and perhaps ANKLE1 expression, and indicate common mechanisms underlying breast and ovarian cancer risk.

- Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence (professor) subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence (soccer hooligans). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%-3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and -0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30-item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the professor category and those primed with the hooligan category (0.14%) and no moderation by gender.

- Photoelectronically active nanostructures that are Self-assembled from organic rnolecules hold the prortu se of tailored functionality.with simple and inexpensive production. Comparison of nanoWires assembled from related componnds can give important insightS into the details of self-assembly and the,conduction meehanisms. We report the photoconductivity of nanofibers that are self-assembled from a porphyrin With long alkyl substituents. In contrast to previously studied porphyrin nanowires, the photoconductivity increases as atthospheric O-2 is increased. This can be explained-using the same model aS used in the previous studies, by assuming a different, line-up of the bands of the nanofilaments. with the electrode Fermi level. However, this model does not explain our observation that-at O-2 concentrations above 1%, the conduction increases with continued- illunation; this may be due to photoactivation of shallow O-2 adsorption sites. The overall conduction level is low even at high O-2 Concentration, because the alkyl substituents form an insulating sheath around the rianofibers. Such inSulation could be valuable in applications where it would prevent cross-talk between signal S darried in different nanofilaments. Schottky barriers at the interface between- organic nanostructures and electrodes strongly affect conduction and photoconduction, and are strongly influenced by atmospheric gases such, as O-2.
