Traumatic Life Events, Posttraumatic Stress Disorder, And Health Outcomes In A Low -Income, Primary Care Population., Bradford West Applegate Jan 2000

Traumatic Life Events, Posttraumatic Stress Disorder, And Health Outcomes In A Low -Income, Primary Care Population., Bradford West Applegate

LSU Historical Dissertations and Theses

Research suggests that individuals with Posttraumatic Stress Disorder (PTSD) have significant dysregulation in a number of physiological indices, especially the sympathetic nervous system (SNS) and hypothalamic-pituitary-adrenal (HPA) axis. Biological theories of PTSD propose that prolonged SNS and HPA axis dysregulation places individuals with PTSD at risk for development of medical morbidity and impairments in health status. The present study examined the following research questions: (a) what is the prevalence of traumatic life events and PTSD in a low-income primary care population? (b) does PTSD predict impairments in self-reported health status after controlling for age, alcohol abuse, tobacco use, and obesity? …

The Effects Of Dietary Fatty Acids And Non -Steroidal Anti -Inflammatory Drugs On Cyclooxygenase-2 Expression., Kyung-Hee Sohn

LSU Historical Dissertations and Theses

Dietary n-3 fatty acids and non-steroidal anti-inflammatory drugs (NSAIDs) were shown to have cancer preventive and tumor regressive effects. Fatty acids and NSAIDs are substrate and inhibitors, respectively, of cyclooxygenase-2 (COX-2), which is a key enzyme in the conversion of arachidonic acids to prostaglandins. Thus, the modulating effects of different types of dietary fatty acids and NSAIDs on the expression of COX-2 are studied here. Results show that both n-3 and n-6 polyunsaturated fatty acids (PUFAs) inhibit Lipopolysaccharide (LPS)-induced COX-2 expression and NF-kappaB activation in macrophages. Results from in vitro cell proliferation study indicate that growth of colon tumor cells …

Biological And Molecular Properties Of Sweet Potato Leaf Curl Virus., Pongtharin Lotrakul

LSU Historical Dissertations and Theses

In 1994, a sweet potato sample showing leaf curl symptoms was collected from the field in Louisiana. When graft-inoculated, Ipomoea setosa reacted with mild upward leaf curling while I. aquatica reacted with a bright yellow mottle. The putative virus was transmitted by the sweet potato whitefly, Bemisia tabaci biotype B, and it was designated the United States isolate of Sweet potato leaf curl virus (SPLCV-US). Four independent Southern blot hybridizations using the DNA-A of different begomoviruses as probes confirmed the presence of begomovirus-like DNA in the infected plants. Fibrillar inclusions and granular aggregates of geminivirus-like particles were observed in the …

Glucocorticoid Regulation Of The Leptin Receptor Signaling System In The Rat., Abram Madimabe Madiehe Jan 2000

Glucocorticoid Regulation Of The Leptin Receptor Signaling System In The Rat., Abram Madimabe Madiehe

LSU Historical Dissertations and Theses

Obesity, a recognized health problem, is associated with cardiovascular disease, diabetes and hypertension. Removal of adrenal steroids by adrenalectomy (ADX) slows the development of obesity. Leptin decreases food intake through effects initiated by activation of the JAK-STAT pathway. Defects in leptin signaling lead to obesity, which is associated with hyperleptinemia and leptin resistance. In chapter 4, leptin induces phosphoenolpyruvate carboxykinase (PEPCK) mRNA expression and increases glucose production in hepatocytes from lean but not obese Zucker rats. This suggests that hyperleptinemia in obesity causes hyperglycemia. In chapter 5, ADX decreased the levels of PEPCK mRNA, and increased leptin receptor mRNA expression …

Effects Of Dietary Phytase Supplementation On Growth, Nutrient Utilization, And Phytate Degradation In Channel Catfish, Ictalurus Punctatus., Weibing Yan

LSU Historical Dissertations and Theses

Phytase supplementation increases the availability of phosphorus in fish diets, and dietary protein utilization might be increased as well by lower phytate concentrations in phytase supplemented diets. Experiments were conducted to determine if weight gain; protein utilization; mineral retention; apparent dry matter, protein and mineral digestibility; and phytate degradation in the stomach of channel catfish fed an all-plant-protein diet could be improved by phytase supplementation. Seven diets were tested: a nutrient complete diet (TC) containing 5% fish meal and six all-plant-protein diets (T1--T6) that contained minimal levels of available phosphorus (0.16%; total P = 0.57%) and zinc (53.37 ppm), but …

The Relationship Of Biomass Allocation And Nutrient Dynamics In Loblolly And Slash Pine Forests., Christopher Ashley Dicus

LSU Historical Dissertations and Theses

Aboveground biomass allocation and its effect on various aspects of N and P dynamics were investigated in loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) stands planted at different spacings. Further, the relationship of nutrient demand and root production was investigated to validate the functional balance hypothesis in forest stands. N mineralization was greater in loblolly pine stands than slash pine, corresponding with greater needle litter N concentration. Both N and P mineralization increased in loblolly pine stands with increasing stand density, the result of greater nutrient input through increased litterfall. There were no species differences in …

The Effect Of Phytase On Nutrient Availability In Diets For Swine And Poultry., Sara Leann Johnston Jan 2000

The Effect Of Phytase On Nutrient Availability In Diets For Swine And Poultry., Sara Leann Johnston

LSU Historical Dissertations and Theses

A series of experiments was conducted to determine the effect of increasing phytase coefficient of variation (CV) in chick diets, and to determine the effect of phytase addition on nutrient availability in diets for swine and poultry. The first experiment (EXP) simulated varying mix uniformity of phytase by alternately providing two diets with two different concentrations of microbial phytase (FTU). Increasing phytase CV had little effect on growth performance, whereas bone ash and breaking strength and Ca and P retention and excretion decreased only at the most extreme CV. These data suggest that a phytase CV of between 34 and …

Third -Party Organization Endorsement Of Products: An Advertising Cue Affecting Consumer Pre-Purchase Evaluation Of Goods And Services., Dwane Hal Dean

LSU Historical Dissertations and Theses

Observation of advertising in current use suggests that a new type of ad is emerging as a product positioning tool. The new ad features third-party organization (TPO) product endorsement as one of the elements of the ad (e.g. "Car of the Year" award by Motor Trend magazine, and "4-star" mutual fund rating from Morningstar). Marketers appear to be using favorable TPO statements about their products to enact their positioning strategy. This dissertation proposed that TPO endorsements are perceived by consumers as extrinsic quality cues, similar to the established quality cues of brand, price, retailer reputation, and warranty. This proposition was …
