Only two genome-wide significant loci associated with longevity have been identified so far, probably because of insufficient sample sizes of centenarians, whose genomes may harbor genetic variants associated with health and longevity. Here we report a genome-wide association study (GWAS) of Han Chinese with a sample size 2.7 times the...

Cytokinins are a group of plant hormones mediating cell division and
differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly
metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion
have been studied extensively. Zeatin metabolic enzymes may be utilized in studying the
regulation of...
Academic success is a salient domain of youth development and is related to positive lifelong outcomes among youth in foster care. However, youth in foster care experience compounding adversities, including maltreatment and foster care placement itself, which put them at risk of academic disengagement and underachievement. Despite these adversities, academic...
During the first full school year of the Covid-19 pandemic, two central contexts for adolescent development—home and school—changed utterly. In Oregon, most middle- and high schoolers attended school entirely remotely from the beginning of the pandemic, in March, 2020, through the end of April, 2021, removing both the supports available...
The effect of nitrogen (N) application on seed yield of Limnanthes
alba was studied for two years at two locations. Seeding following alfalfa
(Medicago sativa L.) was compared to establishment after wheat
(Triticum aestivum L.). Treatments used were a control (no N applied),
and two rates of N (50 and...
The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...
Yeast mannoproteins released during the process of aging wine on the yeast lees have been reported to make important contributions to wine quality. However, few mannoproteins have been identified in wine and their lifespan during aging is unknown. As a first step towards better understanding the contributions of yeast mannoproteins...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
