The Effects Of Aluminum Concentration On Growth Responses In Six Spartina Alterniflora Genotypes, Daniel Farrell Becker Jan 2005

The Effects Of Aluminum Concentration On Growth Responses In Six Spartina Alterniflora Genotypes, Daniel Farrell Becker

LSU Master's Theses

Elevated soluble aluminum concentrations can adversely affect plant growth. During a drought, wetland soils may experience higher than normal soluble aluminum due to the oxidation of metal sulfides and resulting decreases in pH, which mobilizes metallic cations. Louisiana coastal salt marshes were subject to a record-setting drought in the winter and spring of 2000 which was coincident with the die-off of large expanses of salt marsh, termed " brown marsh ". Spartina alterniflora was the primary plant species affected. However, because some individuals within large areas of die-off survived the brown marsh event, they may have been the more resistant …

Modulation Of Adipocyte Genes By Signal Transducers And Activators Of Transcription, Jessica C. Hogan Jan 2005

Modulation Of Adipocyte Genes By Signal Transducers And Activators Of Transcription, Jessica C. Hogan

LSU Doctoral Dissertations

Members of the STAT transcription factor family are expressed in adipocytes, including STATs 1, 3, 5A, 5B, and 6. Although STATs 1 and 5 proteins are known to be induced during adipogenesis, the functions of these STATs in mature adipocytes are not known. Hence we have sought to identify adipocyte genes which are transcriptionally regulated by STATs to elucidate a role of these proteins in fat cells. We have characterized STAT binding sites in the promoters of four adipocyte genes, PPARγ2, LPL, FAS and C/EBPδ. PPARγ2 expression decreases in adipocytes following exposure to IFNγ, an activator of STAT1. IFNγ induces …

Antimicrobial Effect Of Cetylpyridinium Chloride Against Listeria Monocytogenes Growth On The Surface Of Raw And Cooked Shrimp, Tracie Michelle Dupard

LSU Master's Theses

Listeria monocytogenes has emerged as a major foodborne pathogen for the seafood industry due to its psychrotrophic nature and its ubiquitous presence. It has been isolated from soil, sewage, dead vegetative matter, aquatic environments, fecal material, fish, crustaceans, and domesticated animals. As a result, L. monocytogenes has been responsible for several shrimp recalls and has been epidemiologically linked to human listeriosis. Fresh seafood products are highly perishable and their shelf-life is limited by microbiological spoilage. Therefore, when pathogenic microorganisms are involved, it poses a health threat to the general public. The situation is further complicated because seafood processing plants are …

Effects Of Body Size On Goose Behavior: Lesser Snow Goose And Ross's Goose, Jon Einar Jonsson Jan 2005

Effects Of Body Size On Goose Behavior: Lesser Snow Goose And Ross's Goose, Jon Einar Jonsson

LSU Doctoral Dissertations

Body size is highly variable among geese, both at intra- and interspecific levels. Interspecific variation in several behaviors has been attributed to differences in body size in geese: incubation constancy, tendency to maintain family units, and time spent foraging. Body size has important physiological implications for birds, mostly because mass-specific metabolic rate is greater for birds of smaller mass. The Body-size Hypothesis predicts that smaller species deplete their energy reserves at relatively faster rates than do larger species. Hypotheses and conclusions concerning effects of body size on waterfowl behavior often are based on comparisons of species that confront different climates, …

Osteoporosis And Osteopenia Management In Women: Survey, Case-Referent Study, And Interventional Exercise Trial, Rania A. Mekary Jan 2005

Osteoporosis And Osteopenia Management In Women: Survey, Case-Referent Study, And Interventional Exercise Trial, Rania A. Mekary

LSU Doctoral Dissertations

Three studies are presented; the first epidemiological study was a survey of Baton Rouge/New Orleans physicians who manage osteoporosis. When the respondents’ answers were compared to selected guidelines, they displayed poor knowledge regarding osteoporosis prevention, diagnosis, and treatment (X2=39.88; P<0.0001). Rheumatologists and endocrinologists scored globally better on osteoporosis management when compared to ObGyn (OR= 6.98) (CI=2.4; 22.8). Physicians with more years of experience were more knowledgeable of osteoporosis care (OR=1.04) (CI=1.014; 1.071). The second epidemiological study was a case referent study looking at osteoporosis treatment and patient adherence of selected women in Baton Rouge. Results showed that osteoporosis management depended partly on patient adherence. Barriers to patient’s adherence varied from physiological to psychological reasons. Physicians need to provide more explanation and motivation to the patients. Spine was the area most affected and showed more improvement with treatment than the femur (P<0.01). Bisphosphonates were the most effective treatment for the spine (P<0.05). In patients with osteoporosis, being on just calcium and exercise is not enough to counteract bone resorption. They also need to be on an anti-resorptive therapy. Low body mass index, genetics, and history of fractures were negatively correlated to bone mineral density (BMD) increase (P<0.05). The third interventional pilot study was a non-randomized controlled study done on osteopenic postmenopausal women to examine the effect of calcium supplements and core/lower back strengthening exercises on lumbar density and muscle strength. Repeated measures analysis showed that both groups increased in isometric lumbar strength with time (P=0.02). When fosamax and exercise were taken as treatments, with baseline BMD as a covariable, the one-tailed P value of the two-way ANOVA showed a numerically positive but not significant increase in the exercise group (yearly change=2.373 ± 2.625; T value=0.9; P=0.21). Also, the exercise group showed increased feelings of well-being as opposed to the control group who showed no change or worsening. One woman in the control group fractured a bone. Ultimately, osteoporosis management relies on physicians’ knowledge, involvement, and patient adherence. Calcium, exercise and anti-resorptive treatments are needed in case of osteoporosis. Calcium supplements and site-specific strengthening exercises may be enough in case of osteopenia.
