The nursery industry plays a critical role in Oregon's economy. An increase in wood-boring insect, or borer, activity has impacted the industry. The goal of this research is to determine key borer species in the nursery industry, flight times so targeted spray schedules can be established, and assess grower knowledge...
Age-related decline in the capacity of endogenous antioxidant systems
complicates pharmaceutical use by the elderly by potentially increasing the toxicity of
some compounds. Of particular interest is chemical detoxification via glutathione (GSH)
and attendant GSH-requiring detoxification enzymes, e.g. GSH peroxidases (GPX) and
GSH S-transferase (GST). These enzymes have been shown...
Northwest cherry cultivars including Prunus avium 'Bing', Prunus avium 'Rainier', Prunus avium 'Royal Anne' and Prunus cerasus 'Montmorency' were separated into epidermal tissue, flesh and pit and cryogenically milled with liquid nitrogen. These samples as well as whole samples from each variety were extracted with acetone followed by a chloroform...
Collaboration is crucial when advancing in scientific research. One person cannot
study all aspects of a system. That is why it is important for the scientific community to
communicate with each other and stay updated on research being conducted in other labs
around the world. In my research, I was...
The following paper is an objective view on the viability of growing the truffle Tuber melanosporum in the Willamette Valley. Included in this study are the history of the truffle, biological cycle, habitat description, method of cultivation and an enterprise budget for commercial production in the Willamette Valley. The truffle,...
COUP-TF interacting protein 1 (CTIP1) is a novel C2H2 zinc finger protein that mediates transcriptional repression of ARP1, a member of the COUP-TF subfamily of orphan nuclear receptors [1]. Here we show that CTIP1 interacts with heterochromatin-associated protein 1 (HP1) in vitro and in cells. This
interaction suggests the existence...
Chlamydiae are obligate intracellular bacterial pathogens with a unique biphasic life cycle that consists of an infectious but non-dividing form, called elementary bodies (EB), and a noninfectious but metabolically active form, called reticulate bodies (RB). Chlamydia has an unusual process of cell division of which still remains uncharacterized subject matter;...
Saturated hydraulid conductivity (Ks) is a central soil physical property in determining water movement and contaminant transport through soils; hence modeling this system requires an accurate determination of K. Decimeter-scale KS measurements employing cores or infiltrometers are used frequently, but field-scale KS values are required to encompass the full range...
Raspberry bushy dwarf virus (RBDV) infects red raspberry and black raspberry worldwide. Infection causes reduced vigor and drupelet abortion leading to crumbly fruit and reduced yields. While this crumbly fruit can still be used in juice, jam, and preserves, it cannot be used for the more valuable fresh and individually...
Llama reproductive physiology is unique when compared with other livestock species. Llamas carry 95-98% of all pregnancies in the left uterine horn. It is believed that there is a physiological difference between the uterine horns that contributes to this phenomenon. This study examined the uterine environment for protease and protease...
Grain protein concentration of wheat is influenced by numerous factors. When determining a wheat variety's ability to produce protein, the plant's ability to uptake and translocate nitrogen is critical. A greenhouse study was conducted to assess differences in nitrogen use among different wheat varieties. The objective was to determine if...
Cucurbits are grown in production agriculture in Oregon as well as in smallholder agriculture in tropical South America. Experimental research was performed at the OSU Research Farm in 2001 with direct-seeded cucurbits, and literature reviews were conducted to develop a characterization of smallholder farming in tropical South America. The two...
Polycyclic aromatic hydrocarbons (PAH) are common pollutants of aquatic systems in urban environments. Due to their lipophilicity, persistence, toxicity and carcinogenicity, they are chemicals of considerable concern. The Portland Harbor includes a large industrial section with numerous current and historic sources for PAH contamination. Runoff from a large metropolitan area...
Cell lines deficient in certain genes of the DNA mismatch repair (MMR) system show a marked resistance to the cell killing or apoptotic effects of DNA alkylating agents. The molecular mechanism for this resistance is not yet understood, but is currently of great interest because of the recent use of...
A set of flour samples with protein content ranging from 9.7 - 13.3 % was used for this study to evaluate the effectiveness of HMW-GS, SEHPLC and mixograph characteristics as screening tools for noodle texture. The sample set had a large variation in HMW-GS composition with Payne score ranging from...
Sarcocystis neurona is the 1responsible for the disease Equine Protozoal Myeloencephalitis (EPM). Exposure rates to S. neurona across the United States is about 50%, yet only about 2% of exposed horses develop EPM. The cell-mediated immune (CMI) response is hypothesized to be important for protective immunity against this disease. The...
The cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae) is a serious
pest of cruciferous crops (i.e. broccoli, cabbage, turnip, rutabaga) in North America and
Europe (Coaker and Finch, 1971; Whistlecraft et al., 1985). The adult flies lay eggs
around the base and in cracks at the soil surface around wild...
