The identification of DNA sequence variants underlying human complex phenotypes remains a significant challenge for several reasons: individual variants can have small phenotypic effects or low population frequencies, and multiple allelic variants may act in concert to affect a trait. We evaluated the combined effect of allelic variants in seven genes involved in high-density lipoprotein (HDL) metabolism, using forward stepwise regression. Analysis of all known common single-nucleotide polymorphisms (SNPs) in the seven candidate genes revealed four variants that were associated with incremental changes in HDL cholesterol levels in three independent samples. Conversely, analysis of 660 polymorphisms in eight genes that …

Biology And Host Specificity Of Gall-Inducing Acythopeus Burkhartorum (Coleoptera: Curculionidae), A Biological-Control Agent For The Invasive Weed Coccinia Grandis (Cucurbitaceae) In Guam And Saipan, Anantanarayanan Raman, Zerlene T. Cruz, Rangaswamy Muniappan, Gadi V.P. Reddy

Faculty Publications

An introduced cucurbit Coccinia grandis (Linnaeus) Voigt has grown into problem proportions in Hawaii and the Pacific islands of Guam and Saipan. The biology of Acythopeus burkhartorum OBrien, 1998, a potential biological-control agent of C. grandis, has been described. By inducing the gall a sink for nutrients and by deriving nutrition, A. burkhartorum places C. grandis under stress. Especially during the late larval stage, the weevil displays an unusual behaviour of shredding dry gall tissues with its mandibles to prepare the pupal case and using the shredded sclerenchyma fibres to fill the open and cut ends of the pupal case. …

Voices In Cultural Heritage Preservation: A Comparative Study Between New Orleans And Changting (China), Guiyuan Wang Jan 2007

Voices In Cultural Heritage Preservation: A Comparative Study Between New Orleans And Changting (China), Guiyuan Wang

LSU Master's Theses

This is a comparative study between the historic preservation in two countries – the United States (New Orleans) and China (Changting). The main questions are how the voices of different groups become foregrounded or effaced in the dynamics of the political process. Pierre Bourdieu’s concepts -- social capital, cultural capital, and symbolic capital – are applied. The historic preservation in the United States is distinct from that in China. First, the national structures of governments are different, and the historic preservation systems are established in dissimilar ways. Second, at the local level, the question, that who take part in historic …

Reevaluating Age In Subadult Remains In Response To Secular Changes In Skeletal Growth, Katherine Ann Blackwelder Jan 2007

Reevaluating Age In Subadult Remains In Response To Secular Changes In Skeletal Growth, Katherine Ann Blackwelder

LSU Master's Theses

The goal of forensic anthropology is the analysis and identification of human skeletal remains in a medicolegal context (Byers 2005:1-2). A forensic anthropologist can determine the age of subadult remains by various means, including dentition, centers of ossification, cranial suture closure, and epiphyseal union. Epiphyseal union is when all bones have completed their growth and fused, which happens for all bones by early adulthood. In this way, a forensic anthropologist can analyze the extent of epiphyseal union to determine the age of a deceased individual. This is done by comparing the skeletal remains to age-specific x-ray images of bones featured …

Equine Obesity-Related Hyperleptinemia, Nan Killen Huff Jan 2007

Equine Obesity-Related Hyperleptinemia, Nan Killen Huff

LSU Doctoral Dissertations

Plasma leptin concentrations in obese adult horses have been shown to vary widely, and horses tend to fit into two groups: low leptin (<10 ng/mL) and hyperleptinemic (10 to 50 ng/mL). Observations over time revealed that the hyperleptinemic condition was consistent, possibly indicating a relatively permanent underlying cause. Based on these observations, three experimental approaches were used to further study equine obesity-related hyperleptinemia. The first experiment determined the prevalence of hyperleptinemia among postpartum, lactating mares, evaluated its consequence on their re-breeding success, and investigated correlations between leptin levels in lactating and non-lactating mares. Postpartum mares (n = 198) and non-foaling mares (n = 31) were categorized based on their leptin status: normoleptinemic or hyperleptinemic. Leptin in the lactating mares averaged 4.8 ng/mL, and 11 of the 198 (13%) displayed hyperleptinemia. Leptin in the non-lactating mares averaged 7.5 ng/mL, with 9 mares (29%) displaying hyperleptinemia. Of the 198 lactating mares bred, 81% became pregnant; there was no effect of leptin status on re-breeding success. To study one possible cause for hyperleptinemia in well-fed horses, a second experiment explored polymorphism(s) within exon 2 of the equine leptin gene. The DNA from five hyperleptinemic and five normal mares of high body condition was used to analyze exon 2 of the leptin gene for polymorphisms. Based on the 10 mares tested, there was no polymorphism in exon 2 of the equine leptin gene; therefore, polymorphism is not a likely explanation for the high vs. low leptin difference. The third experiment explored the possible effects of hyperleptinemia on the endocrine and immune systems. Endotoxin was given to mares and geldings to investigate the role and/or regulation of leptin in the pro-inflammatory cytokine response. Of the endpoints measured, only platelet count differed between normal and hyperleptinemic horses. Endotoxin infusion caused the expected pro-inflammatory cytokine and endocrine responses, but leptin status was not a significant factor for any endpoint. It is concluded that hyperleptinemia in mares is not associated with polymorphism in exon 2 of the leptin gene, does not affect re-breeding rates of foaling mares, and does not alter the endotoxin-induced responses of the endocrine and immune systems.
