The Influence Of Dietary Protein On Serum Lipid Levels Of Premenopausal Women, Ellen Speiden Parham

Doctoral Dissertations

(From the Introduction)

Serum lipid levels of young women are of particular interest because, in a population riddled with atherosclerosis, premenopausal women seem to have a relative immunity both to severe hyperlipidemia and to those diseases thought to be related to it. The diet of this heterogeneous population is characterized by high intakes of animal protein, animal fat, and sugars.

Research has shown that the type and quantity of fat and carbohydrate have varying degrees of influence on serum lipid levels. Various micronutrients are also implicated. Animal experiments using wide ranges of protein intake suggest that under some …

Forest Soil Characteristics As Influenced By Vegetation And Bedrock In The Spruce-Fir Zone Of The Great Smoky Mountains, James Alvis Wolfe

Doctoral Dissertations

The present study sought to determine differences in soil characteristics related to spruce-fir and beech-birch vegetation in the Great Smoky Mountains when other factors were held as nearly constant as possible. An attempt was made to evaluate the influence of bedrock on soil characteristics and vegetation patterns. Hopefully this investigation may contribute to a greater understanding of the perplexing vegetation mosaic found at higher mountain elevations.

The Great Smoky Mountains of eastern Tennessee and western North Carolina constitute the portion of the Unaka Range situated between the Little Tennessee and Pigeon Rivers. Although metamorphosed, the rocks of Unakas, the westernmost …

Inhibition Of Cysteine Oxidation In Vitamin E Deficiency, Helen Raisty Rutledge

Doctoral Dissertations

Since previous results in this laboratory had indicated that vitamin E was necessary in vivo not only for the optimal sulfation of mucopolysaccharides, but also for the oxidation of neutral sulfur to sulfate, the ability of whole liver homogenates from vitamin Esufficient and -deficient rats to convert cysteine to sulfate was investigated. Then an attempt was made to determine the specific site of the decreased oxidation of cysteine or its intermediate oxidation products. Since several alternative pathways have been proposed in animals for the ultimate oxidation of the sulfur of cysteine to sulfate and the use of the sulfate formed, …
