There is growing interest in using biocrusts (assemblages of cyanobacteria, lichens, mosses, and other taxa in various proportions covering the upper few millimeters of the soil surface) to assist in restoring ecosystem function and native plant communities in dryland ecosystems. Biocrusts can be transplanted and established using jute or thatch,...
The objective of this project was to evaluate various culturing
and isolation techniques of Campylobacter jejuni and to develop methods
to detect the organism in foods. The morphological, cultural and biochemical
characteristics of C. jejuni were studied using developed
microbiological methods. A variety of media, broths, microaerophilic
atmospheres and diluents,...
Water use restrictions are continuing to have an impact on the way turf is managed today and will be managed in the future. The objective of this research was to evaluate the irrigation requirements of ten newly established cool-season turfgrass species maintained under two different mowing height and nitrogen fertility...
The study was designed to assess the efficacy of Lou and Charlson's
(1991) social cognition training program for deaf adults. Sixteen deaf
adult subjects who were vocational rehabilitation clients, and who had
been identified as experiencing difficulties in social functioning, were
assigned to receive a eight-week training program designed to...
Current retail food distribution practices, microbial quality of
bakery products, and the potential for growth of food borne pathogens
(Staphylococcus aureus, Salmonella typhimurium, and Bacillus cereus)
were examined using pumpkin pie as a model.
The pumpkin pies, as obtained from the retail outlets, showed contamination
with food pathogens. The aerobic...
The objective of this study was to determine the effects of processing on sodium - potassium and calcium - phosphorus ratios in tuna canned in oil and in water, peanut butter, white and whole wheat flours. Mineral levels were determined by atomic absorption spectrophotometry in food samples at various stages...
Absorption of iron from foods has been reported to be inhibited by
various factors including some diet components. Fiber from different
sources has been observed to bind ferrous iron. This may be the reason
for iron deficiencies observed in populations that consume diets high in
non-digestible materials.
The effect of...
Glycomacropeptide (GMP) is a bioactive peptide found in the dairy product whey, along with whey protein isolate (WPI). Past studies have shown that digested GMP retains bioactivity in rodent guts. This study tested whether GMP or GMP-derived peptides or whey protein or whey protein-derived peptides inhibit pro-inflammatory cytokines. THP-1 cells...

BACKGROUND: The association of vitamin D with heart attack and stroke remains unclear.
METHOD: Using data from the Osteoporotic Fractures in Men Study (MrOS), we collected
dietary vitamin D data from 5,995 participants and serum (25)OH vitamin D from 1,606
participants. The association of vitamin D with prevalent heart attack...
Biological studies were conducted on a histozoic myxosporidan
Myxobolus insidiosus (Wyatt and Pratt, 1963) from the musculature of
Oncorhynchus tshawytscha (Walbaum). This organism is known to
occur in spring chinook salmon in Oregon and coho salmon O. kisutch
(Walbaum) in Washington. In addition Myxobolus kisutchi (Yasutake
and Wood, 1957) was...
