Isolated embryos showed relatively little dormancy during grain-filling and most varieties exhibited a window of decreased ABA-responsiveness around the period of maximum dry matter accumulation (physiological maturity). Susceptibility to PHS was assessed by overhead misting of either isolated ears click here or whole plants during AR; varieties were clearly distinguished using both methods. These analyses allowed an investigation of the interactions between
the different components of seed development, compartments, and environment for the six varieties. There was no direct relationship between speed of caryopsis AR and embryo dormancy or ABA-responsiveness during seed maturation. However, the velocity of AR of a variety was closely associated with the degree of susceptibility to PHS during AR suggesting that these characters are developmentally linked. Investigation of genetic components of AR may therefore aid breeding approaches to reduce susceptibility to PHS.”
“Incorporating UV-sensitive electron
transport layers (ETLs) I-BET-762 into organic bulk heterojunction (BHJ) photovoltaic devices dramatically impacts short-circuit current (J(sc)) and fill factor characteristics. Resistivity changes induced by UV illumination in the ETL of inverted BHJ devices suppress bimolecular recombination producing up to a two orders of magnitude change in Jsc. Electro-optical modeling and light intensity experiments effectively demonstrate that bimolecular recombination, in the form of diode current losses, controls the extracted photocurrent and is directly dependent on
the ETL resistivity. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3488609]“
“We examined whether p53 codon 72 polymorphism confers prostate cancer risk by conducting a meta-analysis. Two investigators independently searched the Pubmed, Embase and CBM databases. This meta-analysis was made of seven case-control studies, that included 892 prostate cancer cases and 1020 healthy controls. Meta-analysis results based on all the studies showed no significant association between p53 codon 72 polymorphism and prostate cancer risk in the comparisons of Pro allele vs Arg allele; Pro/Pro + Pro/Arg vs Arg/Arg; Pro/Pro vs Pro/Arg + Arg/Arg; Pro/Pro Volasertib ic50 vs Arg/Arg, and Pro/Arg vs Arg/Arg [odds ratio (OR) = 1.09, 95% confidence interval (CI) = 0.87-1.36, P = 0.47; OR = 1.22, 95% CI = 0.86-1.73, P = 0.27; OR = 1.03, 95% CI = 0.62-1.72, P = 0.91; OR = 1.22, 95% CI = 0.66-2.26, P = 0.52; OR = 1.25, 95% CI = 0.84-1.87, P = 0.27, respectively]. In the subgroup analysis by ethnicity, no association was found between p53 codon 72 polymorphism and prostate cancer risk both in Caucasian and Asian populations. We found no association between p53 codon 72 polymorphism and prostate cancer risk.”
