Immobilized proteins are integral components of a number of important technologies, including the principal component of many biosensors, as functional coatings in various implants, as catalysts is industrial biosynthesis, and as the building blocks of next-generation nanotechnologies. Despite their ubiquity, relatively little is known about the processes that shape immobilized...
Understanding the mechanisms regulating mitochondrial respiratory function and adaptations to metabolic challenges, such as exercise and high dietary fat, is necessary to promote skeletal muscle health and attenuate metabolic disease. Autophagy is a constitutively active degradation pathway that promotes mitochondrial turnover and is suppressed by insulin and activated by exercise....
Forested landscapes in the Pacific Northwest have changed drastically in the last Century with large-scale wildfires, and increased extent and frequency of commercial timber harvests. Thus, landscapes once dominated by older forest cover types became a matrix of younger forests with patches of older forests dispersed throughout. These younger forests...
One of the biggest hurdles for a juvenile salmonid (Oncorhynchus mykiss) is migrating downstream from freshwater spawning grounds to the ocean. Juveniles from wild broodstock were reared from the South Santiam River for more than 1 year at the Oregon Hatchery Research Center (OHRC) in Alsea, OR. The fish were...
In horticultural nurseries for container-grown plants, production and sales have been threatened by the presence of a quarantined plant pathogen, Phytophthora ramorum (causal agent of sudden oak death). Infested nursery beds are an important source of P. ramorum, which can initiate disease through movement with surface water to infect roots...
Aerobic organisms have evolved many sensory mechanisms that allow
response to oxidants in the environment. One area of interest is the relationship
between the activity of the tumor suppressor protein p53 and the redox state of
thioredoxin. Human p53 activity is severely compromised in budding yeast lacking
thioredoxin reductase. Evidence...
The purpose of this research was to determine whether hybridization between Amelanchier denticulata. (H.B.K.) Koch and Amelanchier nervosa (Decaisne) StandL occurs in Oaxaca, Mexico, and to evaluate components of yield and germination characteristics and seed dormancy of Amelanchier denticulata. Amelanchier nervosa and Amelanchier denticulata samples and morphological characters were used...
Protein microcapsules (PM) were developed as a tool for investigating aspects of dietary protein utilization by mussels, Mytilus edulis trossulus. Digestion of PM in vitro by protease, trypsin, amylase and extracts from the gut of mussels varied significantly depending on the type of protein encapsulated or whether carbohydrates were added...
