The Effect Of Food Deprivation On Cigarette Smoking In Females, Darla E. Kendzor Jan 2007

The Effect Of Food Deprivation On Cigarette Smoking In Females, Darla E. Kendzor

LSU Doctoral Dissertations

Studies have shown that food deprivation is associated with increases in the self-administration of nicotine and other substances in laboratory animals. However, little is known about the effects of food deprivation on substance use in humans. The purpose of the present study was to compare smoking rates, expired carbon monoxide levels, and smoking topography in 15 female participants during a state of acute food deprivation and in a non-deprived state. A within-subjects design was utilized to test the primary hypotheses that smoking rate and expired carbon monoxide levels would be greater among the participants in the food-deprived condition than in …

The Agriculturalists Of The Poole-Rose Ossuary: A Study Of The Femora And Tibiae, Melissa L. Moreno Jan 2007

The Agriculturalists Of The Poole-Rose Ossuary: A Study Of The Femora And Tibiae, Melissa L. Moreno

LSU Master's Theses

Dr. Heather McKillop of Louisiana State University was asked by the Alderville First Nation of Ontario in 1990 to excavate the Poole-Rose ossuary in 1990. This mass burial consisted of hundreds of mixed disarticulated and de-fleshed individuals as well as three articulated individuals laid in flexed positions. No artifacts were discovered with the bodies. Due to the absence of stratified soil layers from different periods, McKillop estimated the ossuary occurred during one burial event- “The Feast of the Dead.” Radiocarbon dating found the ossuary to be from A.D. 1550 ± 50 years (McKillop and Jackson 1991). I estimated sex according …

Rna:Dna As An Indicator Of Nutritional Condition And Growth In Larval Naked Goby, Gobiosoma Bosc, Michelle C. Satterwhite Jan 2007

Rna:Dna As An Indicator Of Nutritional Condition And Growth In Larval Naked Goby, Gobiosoma Bosc, Michelle C. Satterwhite

LSU Master's Theses

Developing organism-based metrics for assessing habitat quality is an important tool in conservation and restoration of aquatic habitats. The use of the RNA:DNA ratio as an early indicator of habitat effects on growth of nekton species has been suggested, but requires species-specific laboratory assessment prior to field application. We used food availability in laboratory treatments to simulate differences in habitat quality. Wild Gobiosoma bosc eggs were collected using nest-traps constructed of PVC pipe. Eggs from several different nests collected in the field were hatched in the lab, yielding larvae that were randomly assigned to three feeding treatments in two replicate …

Detection Of Vibrio Vulnificus By Direct Colony Immunoblot, Reshani Nisansala Senevirathne

LSU Master's Theses

Vibrio vulnificus (Vv) is a natural occurring bacterium of world wide estuarine environments, which concentrate on filter feeding shellfish. Under cooked seafood contaminated with this pathogen is a leading cause of 95% of seafood-related, foodborne deaths. The development of a rapid, reliable and user-friendly method for Vv enumeration would help to reduce mortality rate. A direct colony immunoblot (DCI) method was developed and used as a rapid enumeration with high sensitivity and the specificity. This method was optimized using Vv agar plates incubated for 16 h at 35 °C. Colonies were transferred from incubated plates to polyvinylidene fluoride (PVDF) membranes …

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.

Sensory Characteristics And Optimization Of A Low-Sodium Salt Formulation And Its Food Application, Armen Khachatryan Jan 2007

Sensory Characteristics And Optimization Of A Low-Sodium Salt Formulation And Its Food Application, Armen Khachatryan

LSU Doctoral Dissertations

Excessive consumption of sodium is associated with high blood pressure in people. Reduction of sodium intake and replacement of salt with salt substitutes are an essential component of the primary prevention of hypertension. Potassium chloride is the most widely used salt substitute. However, when used in large amounts, it imparts bitterness and metallic aftertaste. Therefore, bitterness masking agents need to be used in salt substitute formulations. L-Arginine has been reported to have bitterness masking properties. No research has yet been conducted to investigate the effects of KCl and L-Arginine on the perception of saltiness and bitterness in the mixture of …

Intracellular Lipids In Bos Indicus And Box Taurus Oocytes, Casey Bryant Ballard Jan 2007

Intracellular Lipids In Bos Indicus And Box Taurus Oocytes, Casey Bryant Ballard

LSU Master's Theses

It has been proposed that Bos indicus when compared with Bos taurus embryos are more sensitive to cryopreservation procedures due to higher intracellular lipid content of the embryos. With cyropreservation of Bos indicus embryos increasing for export, it is essential to improve the viability of these cryopreserved embryos. In Experiment I, M-II oocytes from mice, pigs and cows were subjected to two different procedures to evaluate lipid content. The lipid content present in pig oocytes was significantly (P<0.05) higher when compared with mouse and cow oocytes. Pig oocytes had a lower settling point in the sucrose buoyant density gradient and higher Nile Red units, which indicated higher lipids present in the oocytes. In Experiment II, it was determined that M-II oocytes aspirated from superstimulated Brahman donors were significantly higher (P<0.05) in lipid content compared with English breed donors. The lipid content present in Brahman oocytes was higher when compared with English breeds when tested with a sucrose buoyant density gradient and Nile Red staining. In addition, donor females with higher body condition scores were significantly (P<0.05) higher in oocyte lipid content when compared with donor females of lower body condition scores. Furthermore, animal body condition scores, cholesterol and triglyceride levels prior to oocyte aspiration may be indicators of intracellular lipids in the oocytes and embryos. To our knowledge, this is the first report that evaluated intracellular lipid content of M-II oocytes of different beef breed types using a sucrose buoyant density gradient and Nile Red staining.

Particle And Dredge-Scale Kinetic Studies Of Hydrophobic Organic Chemical Desorption From Sediment, Justin Edward Birdwell Jan 2007

Particle And Dredge-Scale Kinetic Studies Of Hydrophobic Organic Chemical Desorption From Sediment, Justin Edward Birdwell

LSU Doctoral Dissertations

The discharge of hydrophobic organic chemicals (HOCs) and other hazardous substances from anthropogenic sources to surface waters and the atmosphere has led to the widespread contamination of bottom sediments throughout the world. HOCs collect in sediments due to their affinity for organic matter and other sorbents present on and within their solid matrices. There is interest in the movement of HOCs from historically contaminated, resuspended sediments to surface waters due to the connection between chemical desorption and bioavailability. Quantitatively accurate predictions of contaminant concentrations in environmental media are needed for reliable risk assessment and to develop strategies for protection of …

A Home-Based Intervention To Promote Physical Activity In Low Income African American Adults, Dorothy Fauntleroy Whitehead Jan 2007

A Home-Based Intervention To Promote Physical Activity In Low Income African American Adults, Dorothy Fauntleroy Whitehead

LSU Doctoral Dissertations

Physical activity has long been regarded as a key component to a healthy lifestyle; however, the U.S. has disturbingly high rates of sedentary behavior and related chronic illnesses (National Center for Chronic Disease Prevention and Health Promotion, 2003). While many studies have attempted to address inactive lifestyle, few have reached out to high risk groups, such as African Americans and low income individuals. A recent review of the physical activity literature among African Americans called for more research with this population and encouraged future studies to focus on enduring exercise behavior (at least 6 months post intervention) and use theory-based …

Watershed-Scale Patterns Of Seaward Migration In Lentipes Concolor, A Hawaiian Stream Goby, Mark Gordon Mcrae Jan 2007

Watershed-Scale Patterns Of Seaward Migration In Lentipes Concolor, A Hawaiian Stream Goby, Mark Gordon Mcrae

LSU Doctoral Dissertations

The native stream fishes of the Hawaiian Islands are uniquely adapted to colonize and thrive in lotic habitats in this extremely isolated archipelago. Chapter 1 of this dissertation introduces the five native fishes of Hawaii's streams and describes the variety of lotic habitats they occupy. All five species have amphidromous life cycles, and, as such, their larvae must migrate to the ocean soon after hatching. Of the five species, Lentipes concolor is able to scale Hawaii’s highest waterfalls during the migration back into fresh water, and therefore inhabits the widest variety of stream types. Adult L. concolor are found a …

Dna-Binding And Oligomerization Properties Of A Functionally Distinct Dps Homolog, Dps-1 From Deinococcus Radiodurans, Gargi Bhattacharyya Jan 2007

Dna-Binding And Oligomerization Properties Of A Functionally Distinct Dps Homolog, Dps-1 From Deinococcus Radiodurans, Gargi Bhattacharyya

LSU Doctoral Dissertations

Dps (DNA protection during starvation) proteins play an important role in the protection of prokaryotic macromolecules from damage by reactive oxygen species. The Dps homolog, Dps-1, from the radiation-resistant bacterium Deinococcus radiodurans has an extended N-terminal tail. In the crystal structure of Dps-1, the first ~30 N-terminal residues are invisible and the remaining 25 residues form a loop that harbors a novel metal binding site. The data presented here show that retention of this N-terminal metal site is necessary for formation of the dodecameric protein assembly. Previous studies have suggested that the lysine-rich N-terminus of Dps proteins participates in DNA …
