A Study of Type I Hypersensitivity (Anaphylaxis)
Type I hypersensitivity reactions were studied in vitro using the Schulz-Dale Assay. This assay involved the suspension of pieces of sensitized mouse ileum (smooth muscle of the gut) in an organ bath to allow exposure to ...
Glucoprivic Regulation of Puberty Onset
The purpose of our studies was to determine 1) if rats experience hypoglycemia during diet-restriction when puberty is delayed, and 2) if histaminergic pathways mediate glucoprivicinduced delay in puberty onset. Plasma ...
Pollen Feeding and Its Effect on a Generalist Predator, the Chinese Praying Mantid, Tenodera sinensis
The Chinese praying mantid, Tenodera sinensis (Saussure), is a univoltine generalist predator that hatches early in the spring and must oviposit in the fall. At both crucial times of early nymph development and oogenesis, ...
Insights into the Factors Controlling the Distributions of the Narrow Endemic, Helenium virginicum and its Widespread Congener, H. autumnale, Through a Study of Their Relative Competitive Abilities and Growth Rates
We undertook a growth and competition study of H. autumnale and H. virginicum to gain insight into the causes of their distributions. We used a multiple de Wit replacement series to study competition, run concurrently with ...
Adaptations of Energy Systems in Competitive Swimming: A Physiological Evaluation of a NCAA Division III Training Program
The training effects of a 21-week swim season on anaerobic
threshold (AT) , maximum oxygen consumption (mV02) , and plasma
lactate were studied with six members of the Washington and Lee
University swim team as subjects. ...
Determining the Primers and Methods for T-RFLP Analysis of Yellowstone National Park Soil and Soil from Washington and Lee's Campus to be Used with the LI-COR 4300
At the onset of our research, our goals consisted of determining the primers that should be used in the T-RFLP protocol with the LI-COR 4300, optimizing the conditions for soil DNA extraction, PCR, and T-RFLP, and ultimately ...
Detection and Characterization of Potential Carcinogens in Eucalyptus and Chaparral Herbal Teas
Four different mutant strains of Salmonella typhimurium were used in accordance with the Ames mutagenicity assay to detect and characterize any mutagenic properties in two common herbal teas: chaparral and eucalyptus. ...
The Effects of Ethanol on Embryonic Chick Brain Mitotic Activity: A Model for Fetal Alcohol Syndrome
Fetal Alcohol Syndrome (FAS) results from infrequent, high levels of ethanol consumption by the pregnant mother, and leads to microcephaly, growth and mental retardation, and facial disfiguration in offspring. The chick ...
