Ice cores are considered the gold standard for recording past climate and biogeochemical changes. However, gas records derived from ice core analysis have until now been largely limited to centennial and longer timescales because sufficient temporal resolution and analytical precision have been lacking, except during rare times when atmospheric concentrations...
Xanthohumol, a prenylated flavonoid found in hops and beer, possesses a long-standing reputation to improve health. Xanthohumol’s cytotoxicity to a wide variety of cancer cell lines is well-established. Herein we provide further insight into the cytotoxicity of not only xanthohumol, but also its non-estrogenic derivatives, to a number of colonic...
Studies were conducted to determine the influence of formulation and molecular configuration of some chlorinated-phenoxyalkylcarboxylic acid herbicides on their absorption, translocation and metabolism in bigleaf maple, Acer macrophyllum, Pursh. Five to eight year old bigleaf maple seedlings were treated with one percent solutions of carbon 14-labeled herbicids. After three days...
People with intellectual and developmental disabilities (IDD) engage in lesser physical activity (PA) and more time in sedentary activities as compared to those without disabilities. A subset of people with IDD who are most vulnerable to develop habits detrimental to health is the emerging adults who are transitioning from adolescence...
A decline in the oxygen cost of exercise enhances exercise tolerance and performance. Substantial research has shown that dietary nitrate lowers the oxygen cost of exercise in sedentary humans; however, the metabolic determinants regarding how dietary nitrate influences oxygen consumption in skeletal muscle is not known. We addressed this gap...
The Western Lake Survey (WLS) of 1985 documented the status of lake water chemistry across the western US and inferred population representations of various subregions and geomorphic units via statistically analyses. Results from this 1985 study indicated that lakes of the Oregon Cascades had the second most pristine and dilute...
Reinforced concrete (RC) column-footing substructures are widely used to support bridges along critical transportation corridors in Oregon. Those built prior to 1971 were typically designed to resist only gravity loads. Therefore, they are vulnerable to damage or collapse during strong ground shaking. To prevent collapse, seismic retrofits have been developed...
Earth’s atmosphere is unequivocally warming due to CO₂ and other greenhouse gas (GHG) emissions from human activities and this is having widespread impacts on forest ecosystems that provide important services to human societies. Forest ecosystems help regulate atmospheric CO2 concentrations by sequestering carbon in tree biomass and soils, which is...
