Diethylnitrosamine, ethylnitrosourea, and dimethylbenz(a)anthracene DNA binding studies in the rainbow trout

Creator:: Van Winkle, Samina
Abstract:: Dimethylbenz (a) anthracene (EMBA), a carcinogen that requires metabolic activation to produce active metabolites capable of binding to DNA, has been studied in the trout and other fish. Polycyclic aromatic hydrocarbons (PAH) are of importance as they are ubiquitous in the environment and their carcinogenic effects in fish from contaminated...

Effect of polyphosphate on microbial characteristics of seafoods

Creator:: Petchsing, Urairatana
Abstract:: Effect of 6.0% polyphosphate treatment on microbial growth and composition of microbial flora of three representative seafoods were investigated. Polyphosphate treatment washed off microorganisms by 1 log in peeled shrimp (10⁷ to 10⁶ and 10⁶ to 10⁵) and cooked crab meat (10⁶ to 10⁵) and by 2 logs in red...

The significance of glutathione conjugation for aflatoxin B₁ metabolism in rainbow trout and coho salmon

Creator:: Valsta, Liisa M.
Abstract:: In rodent models as well as in fish models there are significant species differences in the susceptibility toward aflatoxin B₁ (AFB₁) carcinogenesis. Mouse is less susceptible toward AFB₁ carcinogenesis than rat. Researchers have come to the conclusion that the lower susceptibility of mice is not a result of less effective...

Ras oncogenes and p53 suppressor genes in fish carcinogenesis models

Creator:: Cheng, Ronshan
Abstract:: A digoxigenin-labeled nonradioactive detection system was used to screen a zebrafish cDNA library for p53-like and ras-like genes. One clone was isolated and identified as an incomplete p53-like gene. The insert size of this clone is 1777 bp, which encodes part of evolutionarily conserved region II and all of regions...

Impact of Preharvest Weathering, Without Sprouting, on the Quality of Soft White Winter Wheat in the U.S. Pacific Northwest

Creator:: Smith, Jordan L.
Abstract:: When wheat is exposed to rain in the period before harvest, it sometimes causes the problem of pre-harvest sprouting (PHS). Wheat that undergoes sprouting has poor end-use quality and is less valuable. In recent years, the U. S. Pacific Northwest (PNW) has experienced increased summer showers sometimes causing widespread PHS....

Two Studies Addressing Practical Needs of Wheat Farmers, Processors, and Breeders : Changes in Falling Number and Alpha-amylase During Grain Storage, and Improved Predictions of Wheat-flour Dough Properties

Creator:: Adams, Mike R.
Abstract:: Wheat (Triticum aestivum) is a globally traded staple food crop. The diverse and pleasing nature of wheat-derived products is a result of the complex interactions of the polymeric components from the wheat endosperm. Changes in the functionality of these polymeric components, as a result of changes in growing conditions or...

Characterization and detection of potential adulterants in apple juice by pattern recognition methods

Creator:: Pilando, Leticia S.
Abstract:: Fruit juice concentrates- hard pear, soft pear, fig, prune, raisin, white grape, and pineapple, and sweeteners-invert beet, invert cane, and high fructose corn syrup (HFCS) were characterized by sugar profiles, nonvolatile acid profiles, UV spectral profiles, and mineral content. These fruit juices and sweeteners were also used to adulterate commercial...

The use of liposomes as encapsulating agents for feeding juvenile Pacific oysters (Crassostrea gigas)

Creator:: Parker, Robert S.
Abstract:: The ingestion, uptake, and metabolism of liposomes by juvenile Pacific oysters (Crassostrea gigas) were studied by several methods in an effort to assess their potential as encapsulating agents. Liposomes composed of egg phosphatidylcholine-cholesterol-stearylamine (7:1:2) formed readily and appeared stable in 20°/oo seawater. Radiotracer studies with liposomes made with ¹⁴C-labeled cholesterol...

Contribution of Farm Level Milk Sourcing on Non-Starter Lactic Acid Bacteria (NSLAB) in Cheddar, and the Assessment of High Resolution Melt Analysis used for Species Identification

Creator:: Baird, Christopher S.
Abstract:: Non-starter lactic acid bacteria (NSLAB) are found at low levels in fresh raw milk and are important to the dairy industry because of their potential impact on the flavor and texture of yogurt, sour cream, and cheese. The purpose of this study was to evaluate three methods for the identification...
