Modulation Of Drug Metabolism By Food Restiction, Paul Kupen Su

Doctoral Dissertations

The effects of the level and duration of feed restriction on the in vitro activities of hepatic drug metabolizing enzyme system were examined in male weanling Sprague Dawley rats fed ad libitum or feed restricted at 15%, 30% and 45% for a period of one to five weeks (Experiment I). Increasing levels and duration of feed restriction resulted in significant progressive increases in hepatic microsomal protein, cytochrome P-450 content and the in vitro activities of microsomal aniline hydroxylase. p-chloro-methly-aniline(PCMA)N- demethylase and p-nitrophenol UDP-glucuronyl transferase activities were unaltered by the feed restriction while cytochrome c reductase activity was significantly decreased. In …

Predictors Of Life Satisfaction Among Young Adults From Low-Income, Rural Areas Of Southern Appalachia, Stephan Maxwell Wilson

Doctoral Dissertations

A person's quality of life has been assumed by some researchers to be related to material and achieved status or to the material conditions of life by other researchers. Individuals' perception of the quality of their lives, however, is an experience of satisfaction. Therefore, researchers have begun to examine how individuals perceive the quality of their lives based upon individuals' internal comparisons of their own expectations and aspirations (i.e., internal referents) as predictors of life satisfaction. These internal referents may not be tied to mainstream American standards or values. Most life satisfaction studies, to date, have concentrated on middle-class, urban …

Effects Of Cadmium, Calcium, Age And Parity On Bone Mineral, Density And Strength In Female Rats, Beverley F. Hammond

Doctoral Dissertations

Weanling female rats were fed diets containing one of three levels of Ca (0.3, 0.6 or 0.9%) and one of four levels of Cd (0, 1, 5 or 10 ppm) in the drinking water. One half of each group was bred first as adolescents (55 days) and the other half as mature (110 days) females. Approximately 10 animals from each group were sacrificed after the first pregnancy and the remaining animals after the fourth pregnancy. Reproductive performance, plasma and bone Ca and P and bone density and strength were measured.

After the first pregnancy, offspring of dams treated with 5 …

A Study Of Fine Structure Development Of Poly(Ethylene Terephthalate) In High Speed Spinning By Using A Pneumatic Drawdown Device, Chi-Chung Bai

Doctoral Dissertations

High speed melt spinning of linear, branched, and high molecular weight poly(ethylene terephthalate) (PET) polymers using a pneumatic drawdown device was carried out in this study. Characterization of the structure of final spun fibers of each polymer and the structure development along the spinline for different mass throughputs and take-up velocities were studied.

The final spun fibers were characterized with various techniques: birefringence, density, wide angle x-ray scattering (WAXS), differential scanning calorimetry (DSC), shrinkage, and tensile testing. A filament cutting technique was utilized and on-line temperature and birefringence measurements were performed to study the PET structure development along the spinline. …
