Dose Response And Functional Consequences Of Choline Induced Changes In Carnitine Homeostasis In Guinea Pigs, James William Daily

Doctoral Dissertations

This study further characterized a newly discovered interaction of two nutrients, choline and carnitine. Increased dietary choline had previously been demonstrated to cause a conservation of carnitine in humans and guinea pigs, and an increased muscle carnitine concentration guinea pigs. The first part of this study compared the effect of varied doses of choline on urinary excretion of carnitine, tissue and whole body carnitine concentrations, and body composition. It was demonstrated that a choline dose of 2 g/kg diet results in a near maximal effect on urinary conservation of carnitine, which is mediated by an increase in the fractional tubular …

Role Of Intracellular Free Calcium In The Obesity And Insulin Resistance Associated With Dominant Agouti Mutations, Jung Han Kim

Doctoral Dissertations

Several dominant mutations at the agouti locus in the mouse cause a syndrome of adult-onset obesity, hyperinsulinemia, and insulin resistance. Although ectopic overexpression of the agouti gene is directly responsible for the disease in these mutations, the precise mechanism is unclear. Intracellular Ca²⁺ ([Ca²⁺]i) appears to have a role in mediating insulin signal transduction, and altered handling of [Ca²⁺]i homeostasis and flux is observed in obese and insulin resistant animals and humans. Data reported here demonstrate that mice carrying the dominant agouti mutation, viable yellow (A^vy), exhibit an elevation of [Ca²⁺]i …

Assessing The Hiv/Aids Knowledge, Attitudes, And Behaviors Of Representative Football Student-Athletes In The Southern Conference, Jamie N. Whited

Doctoral Dissertations

The primary purpose of this investigation was to assess the current level of knowledge, attitudes, and behaviors related to HIV infection and AIDS among representative freshmen and senior football student-athletes from institutions in the Southeastern Conference of the NCAA. The secondary purpose was to assess student-athletes' sport-specific attitudes and knowledge source related to HIV infections and AIDS.

Based on the literature review and input from professionals in the field of sports medicine and AIDS education, a survey instrument was selected. The instrument was divided into six parts. The first part, Modified DiClemente AIDS Knowledge Survey, was a true-and-false scale (31 …

The Influence Of Point-Of-Purchase Cafeteria-Based Nutrition Education Program On High School Students, Magali O. Gamio

Doctoral Dissertations

Male and female high school students participated in an intervention designed to promote behavior change in food selection. The students were divided in two groups. Group I received the point-of-purchase cafeteria-based nutrition education program, and Group II received the point-of-purchase cafeteria based nutrition program plus a brief classroom nutrition education intervention. Evaluation instruments included pre-test, post-test 1, and post-test 2 written questionnaires, which included food practices, nutrition knowledge, attitudes and their perceptions about the school food service and the point-of-purchase intervention.

For behavior change, there was a significant Time Effect for females Group II with a significant decrease in both …
