The Effects Of Oryzanol On Bone Mineral Density In Ovariectomized, Retired Breeder Rats, Heather Compton Colona Jan 2002

The Effects Of Oryzanol On Bone Mineral Density In Ovariectomized, Retired Breeder Rats, Heather Compton Colona

LSU Master's Theses

The accelerated rate of bone loss that occurs after menopause may be reduced by consuming rice bran oil (RBO), which contains natural oryzanol. Three different forms of oryzanol (natural oryzanol, NO; crystalline oryzanol, CO; and solubilized oryzanol, SO) were evaluated in a rat model of postmenopausal women. Retired Sprague-Dawley breeder rats were stratified by weight and assigned randomly to one of five groups for a thirteen week study. Rats were either variectomized (O, n=37) or sham-operated (ShC, n=10) and assigned to control (C) diets (OC, n=10 or ShC, n=10) or one of three forms of oryzanol (NO, n=9; CO, n=9; …

Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt Jan 2002

Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt

LSU Doctoral Dissertations

Research has found that athletes, particularly those involved in "aesthetically-oriented" sports, are at increased risk for engaging in unhealthy weight reduction practices and developing clinical eating disorders. Prevention studies of eating disorders have had some success, but there are very few published studies that address prevention in athletes. This study was designed as an eating disorders prevention program that targeted coaches as change agents. Cheerleading coaches at national or regional conferences attended an intervention workshop or a control workshop. Coaches who attended the intervention workshop received information regarding nutrition, eating disorders, and ways to manage athletes with eating disorders. They …

Who's Not Dieting In America And Who Should Be? Results From The 1994-1996 Diet And Health Knowledge Survey (Dhks 1994-1996), Emily York-Crowe

LSU Master's Theses

The rising rates of obesity and overweight are contributing to higher costs for the individual and the nation, both medically and financially. There is a greater need for education and other preventive measures, but in order to tailor such programs effectively to the individuals most in need, it is important to examine the current trends, knowledge, and practices of adults in the United States. Previous research has examined the prevalence rates and practices of specific populations and individuals in limited geographical locations but, due to obvious constraints, few nationally representative samples have been examined. This study analyzed the results of …

The Effects Of Singing On Blood Pressure In Classically Trained Singers, Kimberly Jaye Broadwater Jan 2002

The Effects Of Singing On Blood Pressure In Classically Trained Singers, Kimberly Jaye Broadwater

LSU Major Papers

Blood pressure readings were taken in four normotensive, classically trained singers of varying age and experience. The results show changes during the systolic and diastolic phases of blood pressure measurements while singing. While systolic blood pressure changes were individualized and random, diastolic blood pressure changes generally showed a direct correlation to changes in intrathoracic pressure. Additional research using a larger subject base involving normotensive, hypertensive, and hypotensive populations is warranted.

A Potential Nutraceutical From Leuconostoc Mesenteroides B-742 (Atcc 13146); Production And Properties, Chang-Ho Chung Jan 2002

A Potential Nutraceutical From Leuconostoc Mesenteroides B-742 (Atcc 13146); Production And Properties, Chang-Ho Chung

LSU Doctoral Dissertations

There is an emerging market for functional oligosaccharides for use in foods. Currently, technology for the production of oligosaccharides is limited to extraction from plant sources, acid or enzymatic hydrolysis of polysaccharides or synthesis by transglycosylation reactions. Oligosaccharides also can be produced using a Leuconostoc fermentation and restricting the polymer size by the addition of maltose. Maltose limits the dextransucrase reaction, yielding high concentrations of a-glucooligosaccharides. Branched oligomers produced by this process were found to be readily catabolized by bifidobacteria and lactobacillus but were not readily utilized by either Salmonella sp., or E. coli, pointing toward their use in intestinal …

Commentary: Considerations For Use Of Racial/Ethnic Classification In Etiologic Research, Jay S. Kaufman, Richard S. Cooper Aug 2001

Commentary: Considerations For Use Of Racial/Ethnic Classification In Etiologic Research, Jay S. Kaufman, Richard S. Cooper

Faculty Publications

Numerous authors have critiqued the use of race as an etiologic quantity in medical research. Despite this criticism, the use of variables encoding racial/ethnic categorization has increased in epidemiology, and most researchers agree that important variation in disease risk is captured by this classification system. Previous discussions have generally neglected to articulate guidelines for appropriate use of racial/ethnic information in etiologic research. The authors summarize the logical, conceptual, and practical problems associated with the "ethnic paradigm" as currently applied in biomedical sciences and offer a set of methodological recommendations toward more valid use of racial/ethnic classification in etiologic studies. These …

Diets Of Wild Versus Released, And Pen-Raised White-Tailed Deer In Southeastern Louisiana, Richard James Meyers Jul 2001

Diets Of Wild Versus Released, And Pen-Raised White-Tailed Deer In Southeastern Louisiana, Richard James Meyers

LSU Historical Dissertations and Theses

Twenty pen-raised white-tailed deer (Odocoileus virginianus) were released into mixed pine-hardwood forest habitat in southeastern Louisiana to compare their seasonal diets to the diets of the wild white-tailed deer population. Microhistological analysis was used to estimate the botanical composition of fecal pellet samples collected from both populations of deer over four consecutive seasons. Wild and pen-raised deer diets were found to be an average of 75.18% similar during the entire year of the study, and were significantly associated during all seasons (P < 0.001), indicating that all deer foraged on similar plant taxa in similar proportions regardless of season. Both populations of deer were found to be predominantly browsers during all seasons, with browse and fruit accounting for a yearly average of >55% of deer diets. Results from this study indicate that rehabilitated or translocated deer released into new environments …

Psychosocial Correlates Of Eating Disorder Symptoms In A Young, Black, Female Sample., Nancy Lee Zucker Jan 2001

Psychosocial Correlates Of Eating Disorder Symptoms In A Young, Black, Female Sample., Nancy Lee Zucker

LSU Historical Dissertations and Theses

The present investigation examined the psychosocial correlates of eating disorder symptoms among a young sample of Black female adolescents. Recent epidemiological investigations have documented higher rates of disordered eating in Black females than had previously been reported. Because of the high prevalence of these symptoms both in majority and in minority populations, many eating disorder researchers are promoting preventive strategies to stem further increases in symptom levels. To this end, several longitudinal investigations have been conducted to delineate the risk factors of disordered eating among White adolescent populations. However, Black adolescents have been minimally represented in these samples. Thus, there …

Parenting Practices As A Moderator Of Exposure To Community Violence., Nicole Francingues Lanclos Jan 2001

Parenting Practices As A Moderator Of Exposure To Community Violence., Nicole Francingues Lanclos

LSU Historical Dissertations and Theses

Numerous studies evidence that urban youth are exposed to epidemic proportions of community violence. Exposure to community violence has been associated with significant levels of distress including aggression, academic difficulties, anxiety, depression, and posttraumatic stress disorder. Although it is clear that children who experience chronic levels of violence exposure are at increased risk for poor developmental outcome, the consequences of exposure are not the same for all children. Parenting factors found to buffer the effects of community violence exposure include family size, parental presence in the home, family support, parenting resources, family cohesion, and strong parental monitoring. It is less …

A Phylogenetic Analysis Of Variation In Reproductive Mode Within An Australian Lizard (Saiphos Equalis, Scincidae), Sarah A. Smith, Christopher C. Austin, Richard Shine Jan 2001

A Phylogenetic Analysis Of Variation In Reproductive Mode Within An Australian Lizard (Saiphos Equalis, Scincidae), Sarah A. Smith, Christopher C. Austin, Richard Shine

Faculty Publications

Saiphos equalis, a semi-fossorial scincid lizard from south-eastern Australia, is one of only three reptile species world-wide that are known to display geographic variation in reproductive mode. Uniquely, Saiphos equalis includes populations with three reproductive modes: oviparous with long (15-day) incubation periods; oviparous with short (5-day) incubation periods; and viviparous (0-day incubation periods). No Saipho populations show 'normal' scincid oviparity (>30-day incubation period). We used mitochondrial nucleotide sequences (ND2 and cytochrome b) to reconstruct relationships among populations from throughout the species' distribution in New South Wales, Australia. Under the phylogenetic species concept, phylogenetic analyses are consistent with the oviparous …

Bollworm (Lepidoptera: Noctuidae) Survival On 'Bollgard' And 'Bollgard Ii' Cotton Flower Bud And Flower Components, J. Gore, B. R. Leonard, J. J. Adamczyk

Faculty Publications

Genetically modified cotton, Gossypium hirsutum L., cultivars ('Bollgard') that produce crystalline proteins from Bacillus thuringiensis (Berliner) are valuable tools for managing lepidopteran insect pests in the United States. However, high numbers of bollworm, Helicoverpa zea (Boddie), larvae have been observed feeding in white flowers of these cultivars. Fresh tissue bioassays were conducted to investigate bollworm survival on Bollgard and 'Bollgard II' cottons. Bollworm survival was higher on square and flower anthers than on other floral structures on 'Deltapine 5415' (conventional cotton) and 'NuCOTN 33B' (Bollgard). Bollworm survival at 72 h was higher on all floral structures from Deltapine 5415 than …

Effects Of The High -Probability Sequence With And Without Extinction In Children With Feeding Disorders., Jennifer Eileen Dawson Jan 2001

Effects Of The High -Probability Sequence With And Without Extinction In Children With Feeding Disorders., Jennifer Eileen Dawson

LSU Historical Dissertations and Theses

The effects of the high-probability instructional sequence, with and without extinction, on increasing compliance to eat in three children with severe food refusal and selectivity were evaluated. Pediatric feeding disorders, in which children refuse most or all food and drink, are a rare and life threatening problem that requires intensive treatment. The majority of behavioral techniques used with feeding disordered children manipulate the consequence of food refusal. The use of antecedent procedures in the treatment of food refusal has been limited. One antecedent technique, the high-probability instructional sequence, involves first presenting the individual with a series of instructions that he/she …

Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley Jan 2001

Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley

LSU Master's Theses

The objective of the first experiment was to determine the effects of storage at 22„aC vs. 4„aC on the motility and percentage of membrane-intact sperm (%MIS) of epididymal mouse sperm. Testicles were allocated into 22„aC or 4„aC treatment groups and stored for 24 or 48 hours. Additional testicles were allocated into the 4„aC treatment for storage for 72 or 96 hours. Sperm was collected and analyzed at each time point. Storage at 22„aC lowered motility and %MIS (P<0.05) when compared with control sperm and 4„aC sperm at both the 24 and 48 hours. Motility and %MIS of 4„aC sperm did not decrease when compared with the control until after 72 hours of storage. The second experiment evaluated the effects of 22„aC vs. 4„aC storage for 24 and 48 hours on epididymal dog sperm. Motility and %MIS of the 22„aC sperm was lower than that of the 4„aC sperm and the control (P<0.05) at 24 and 48 hours. Motility of the 4„aC sperm was lower than the control at 24 and 48 hours (P<0.05), however %MIS was not lower than the control until 48 hours. The third experiment tested the effect of cryopreservation on epididymal dog sperm. Sperm was frozen immediately (A), after 48 hours at 4„aC in liquid (B) or after 48 hours at 4„aC of the whole testicle (C). Both pre-freeze (PF) and post-thaw (PT) motility and %MIS of B and C were lower than A (P<0.05). PT values were lower than PF values in all treatments (P<0.05). PT motility of B was lower than C (0 vs. 35.0¡Ó3.6%). Storage at 4„aC allows collection of motile epididymal mouse and dog sperm for several days after death. Dog testicles can be refrigerated for 2 days and epididymal sperm frozen with PT motility and %MIS of 35 and 62%.

The Association Of Food Cravings And Preferences With Food Intake, Corby Kyle Martin Jan 2001

The Association Of Food Cravings And Preferences With Food Intake, Corby Kyle Martin

LSU Doctoral Dissertations

An ubiquitous assumption about food intake behavior is that people eat the types of foods that they crave and prefer. Food preferences reflect hedonic ratings of the degree to which people like certain foods. The present study investigated the association of food cravings and hedonic ratings with food intake behavior, assessed in the laboratory with a Universal Eating Monitor (Kissileff, Klingsberg, & Van Itallie, 1980). The study sample consisted of 162 adults who completed the Food Craving Inventory (FCI; White, Whisenhunt, Williamson, Greenway, & Netemeyer, 2001), a questionnaire that measures craving, including cravings for specific types of foods (i.e., High …

Spatial Variability And Isotopic Studies Of The Prairie -Forest Transition Soil In Louisiana., Asfaw Bekele Jan 2001

Spatial Variability And Isotopic Studies Of The Prairie -Forest Transition Soil In Louisiana., Asfaw Bekele

LSU Historical Dissertations and Theses

The calcareous prairies of Louisiana are among the most endangered ecosystems in North America. The major threat to this ecosystem is the invasion by woody and herbaceous plants, primarily eastern red cedar (Juniperus virginiana ). The restoration and management of these rare plant communities require a thorough understanding of the soils supporting them. Geostatistical, fractal, and stable isotopic procedures were integrated to study the soil and vegetation spatial variability. The prairie soil was alkaline, the forest soil was acidic, and the transition soil was neutral. The spherical model described the spatial variability of virtually all the soil properties considered with …
