GWAS of 126,559 individuals identifies genetic variants associated with educational attainment.

A genome-wide association study (GWAS) of educational attainment was conducted in a discovery sample of 101,069 individuals and a replication sample of 25,490. Three independent single-nucleotide polymorphisms (SNPs) are genome-wide significant (rs9320913, rs11584700, rs4851266), and all three replicate. Estimated effects sizes are small (coefficient of determination R(2) ≈ 0.02%), approximately 1 month of schooling per allele. A linear polygenic score from all measured SNPs accounts for ≈2% of the variance in both educational attainment and cognitive function. Genes in the region of the loci have previously been associated with health, cognitive, and central nervous system phenotypes, and bioinformatics analyses suggest the involvement of the anterior caudate nucleus. These findings provide promising candidate SNPs for follow-up work, and our effect size estimates can anchor power analyses in social-science genetics.

Effect of plant regulators on growth and flowering of 'Meyer' zoysiagrass

This trial aimed to evaluate the effect of sequential applications of different plant regulators over growth and flower rachis emission of 'Meyer' zoysiagrass (Zoysia japonica). The study was conducted on 15-month old green turfgrass under a randomized complete block design with four replications. The following plant regulator and doses were tested: trinexapac-ethyl (113+113, 226+113, 226+226, 452+113, 452+226, 452+452, 678+339 e 904+452 g a.i./ha-1), prohexadione-calcium (100+100 e 200+200 g a.i. ha-1) and bispyribac-sodium (40+40 e 60+60 g a.i. ha-1), as well as an untreated control. The turfgrass was mowed again at 3.0 cm aboveground and the second plant regulator was applied when 'Meyer' zoysiagrass was between 5.0 and 6.0 cm high. The effect of the treatments was visually rated for visual injury, plant height, height and number of flower rachis, and total dry mass production of clippings. Only bispyribac-sodium had visual symptoms of injury on 'Meyer' zoysiagrass, and no intoxication was observed at 28 days after the second application (DAAB). The sequential applications of trinexapac-ethyl, prohexadione-calcium and bispyribac-sodium reduced by more than 80% the total clipping dry mass produced by 'Meyer' zoysiagrass. All the plant regulators tested also showed promising results in reducing the height and emission of rachis, especially when trinexapac-ethyl was applied at the doses 452+452, 678+339 and 904+452 g a.i. ha-1. 'Meyer' zoysiagrass turfgrass can be handled with the sequential application of a plant regulator, which reduces the need for mowing over a period up to 110 days after the application of the second plant regulator, and it also avoids deleterious visual effects over turfgrass.

Processamento e avaliação da vida-de-prateleira do tucumã (Astrocaryum aculeatum Meyer) desidratado e pulverizado

O presente estudo teve como objetivo processar frutos de tucumã por desidratação e pulverização e avaliar sua vida-de-prateleira em diferentes tipos de embalagens e temperaturas de armazenagem. A parte comestível do fruto foi desidratada, triturada e passada em tamisador para padronização do diâmetro dos grânulos, embalada em três diferentes tipos de embalagens (plástico polietileno, laminado e lata de aço) e armazenada em diferentes temperaturas (4 e 24 °C). Os frutos in natura e desidratados foram analisados quanto a umidade, pH, acidez, açúcares totais e redutores, proteínas, lipídios, cinzas, carboidratos, energia, β-caroteno e equivalente de retinol. O tucumã desidratado e pulverizado foi analisado a cada 30 dias durante 150 dias de armazenagem quanto aos índices de peróxido, de acidez e de iodo e também quanto aos parâmetros microbiológicos. Os constituintes que se destacaram, tanto no fruto in natura quanto no desidratado e pulverizado, foram: lipídios, carboidratos e, conseqüentemente, energia e β-caroteno. Em relação à vida-de-prateleira, todos os tratamentos apresentaram boa estabilidade química e microbiológica durante os 150 dias de armazenamento. Conclui-se que o tucumã desidratado e pulverizado, independente do tipo de embalagem e temperatura de armazenamento, pode ser estocado e consumido por até 150 dias, além de seu potencial nutricional como fonte de energia e β-caroteno.
