"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle
"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle
LSU Master's Theses
This thesis claims that Shakespeare exaggerated the characterization of two figures in Romeo and Juliet, Friar Laurence and the apothecary, to make a statement about the conditions of medical treatment in sixteenth century London. These two figures represent two very different approaches to healing, one that is informed with ancient holistic medical theory and one that is driven by economics, and this work attempts to explain the cultural conditions that warranted such a discrepancy in the play. I address these two medical figures in the contexts of the events of the text, of the contemporary medical profession, and of materialism …

The Determination Of Appropriate Phosphogypsum: Class C Fly Ash : Portland Type Ii Cement Compositions For Use In Marine Applications, Pradyot Sudhakar Deshpande
LSU Master's Theses
Phosphogypsum (PG, CaSO4·2H2O) is a waste by-product produced during the wet manufacturing phosphoric acid process. Phosphoric acid is manufactured by processing phosphate rock that contains relatively high concentrations of naturally occurring radioactive impurities which makes PG a radioactive material. PG also contains certain trace metals including As, Ba, Cd, Cr and Pb and radioactive contaminants such as Radium226 and Uranium238 that pose potential hazard to human health and the environment. According to USEPA, the current allowable disposal method for PG is stack piling. This research was focused on stabilizing PG with Portland Type II …
Evaluation Of Fertilizer And Irrigation Production Systems For Large Nursery Containers, Anthony Lynn Witcher
Evaluation Of Fertilizer And Irrigation Production Systems For Large Nursery Containers, Anthony Lynn Witcher
LSU Master's Theses
Container-grown woody ornamentals require high volumes of water and sufficient nutrients to develop into healthy, high quality plants. The increased awareness of possible contamination of ground and surface water resources from nursery runoff has forced growers to implement higher water use efficiency techniques to maximize fertilizer efficiency and reduce nutrient and irrigation runoff. Components of a large container production system that could affect irrigation volume, substrate nutrition levels and runoff include fertilizer placement, irrigation frequency and irrigation method. Irrigation and fertilization components were evaluated in two experiments to determine which would maximize growth, minimize effluent and reduce the amount of …

Arm Crank Power And Hyperammonemia In Respones To L-Aspartic Acid Supplementation, William W. Edwards
LSU Doctoral Dissertations
PURPOSE: To examine the effect of L-Aspartic Acid (L-Asp) supplementation on short-term arm-crank power (i.e. W·min-1) and exercise-induced hyperammonemia in two gender-specific investigations. METHODS: The male investigation (MALE) used nine highly-trained intercollegiate water polo players (WP) and nine moderately-trained college students (MOD); the female investigation (FEM) used 18 recreationally-trained college students. All exercised to exhaustion on two occasions following counterbalanced double-blind ingestion of 12.5g x 2 of L-Asp or placebo (P). The warm-up phase began at 25 W·min-1 and increased in 25 W·min-1 stages every 30 seconds (constant 100 rpm). Performance began (i.e. the subjects turned …
Characteristics Of Fat Free Yogurt As Influenced By The Incorporation Of Folic Acid, Charles August Boeneke
Characteristics Of Fat Free Yogurt As Influenced By The Incorporation Of Folic Acid, Charles August Boeneke
LSU Doctoral Dissertations
Folic acid fortification is used in the prevention of neural tube defects such as spina bifida and ancencephaly, heart defects, facial clefts, urinary tract abnormalities, and limb deficiencies. Although yogurt is not a good source of folic acid, fortification could aid in prevention of above mentioned defects. Fortification of yogurt with folic acid may or may not change its physico-chemical characteristics. Fat free sugar free yogurt was manufactured using 0, 25%, 50%, 75% and 100% of the recommended daily allowance of 400 micrograms of folic acid. Treatments included addition of folic acid at these levels before and after pasteurization. Lemon …

Two studies were conducted. In the first study, a questionnaire on FCFV and EC was prepared and completed by 611 consumers. The data were analyzed using Probit analysis. In the second study, physical and microbial quality of fresh-cut (FC) apples coated with three whey proteins (30% glycerol added) each at …
Random Centroid Optimization Of Lutein-Enriched Oil In Water Emulsion At Acidic Ph, Armen Khachatryan
Random Centroid Optimization Of Lutein-Enriched Oil In Water Emulsion At Acidic Ph, Armen Khachatryan
LSU Master's Theses
Age-related macular degeneration (AMD) is a physiological condition that affects the elderly, diabetic patients, and leads to loss of vision. There are no effective therapies for AMD. The role of nutrition in preventing AMD is receiving strong scientific scrutiny. Lutein and zeaxanthin have been identified as dietary strategies that can delay the onset of AMD. Consumption of at least six milligrams of lutein per day has been reported to delay the onset of AMD by as much as 43%. However, most available food sources contain such low levels of lutein that it would be difficult to meet the daily requirement. …

Oocyte Production In The Early Postpartum Cow, Oscar Perez
LSU Doctoral Dissertations
The postpartum period has been the focus of numerous studies; however, there is no information available relating to oocyte production in early postpartum cows. Ovaries of early postpartum cows were stimulated with FSH to produce follicular development and oocytes. The objectives of these studies were: (1) to evaluate the use of FSH for oocyte production in early postpartum beef cows, (2) to evaluate follicular response and oocyte quality of beef cows treated with FSH shortly after calving, (3) to evaluate FSH for oocyte production in early postpartum dairy cows, (4) to evaluate responses of FSH-treated, early postpartum beef cows in …
Using Trabecular Architecture Of The Proximal Femur To Determine Age At Death: An Accuracy Test Of Two Methods, Wendy Michelle Jones
Using Trabecular Architecture Of The Proximal Femur To Determine Age At Death: An Accuracy Test Of Two Methods, Wendy Michelle Jones
LSU Master's Theses
Osteologists and forensic researchers are often called upon to determine age at death for skeletal remains. Although there are common methods in wide use, new methods are always sought. This study evaluates the accuracy of two radiographic methods of determining age by looking at the changes in the trabecular architecture of the proximal femur. These two methods are the Szilvassy and Kritscher (1990) method and the Walker and Lovejoy (1985) method. Samples were taken from four skeletal collections. Radiographs were taken of each individual and both Szilvassy and Kritscher’s (1990) phases of trabecular change and Walker and Lovejoy’s (1985) phases …

A survey was mailed to all 313 faculty members identified as actively involved in teaching in any baccalaureate nursing program in Louisiana and 163 valid responses were obtained. The Cultural Diversity Questionnaire for Nurse Educators, a researcher designed instrument intended to measure cultural competence, was the instrument used. It included Likert-type items organized into five subscales representing the components of cultural competence according to Campinha- Bacote’s model of cultural competence (i.e., cultural awareness, …
Immunological, Hematological, And Serum Biochemical Effects Of High Level Dietary Fish Oil And Vitamin E Supplementation In The Dog, Casey J. Leblanc
Immunological, Hematological, And Serum Biochemical Effects Of High Level Dietary Fish Oil And Vitamin E Supplementation In The Dog, Casey J. Leblanc
LSU Doctoral Dissertations
Inflammation is a component of the innate immune response. However, severe or prolonged inflammation can be detrimental. Dietary n-3 fatty acid supplementation has proven clinical benefits in chronic inflammatory diseases, most likely due to reduced synthesis of inflammatory mediators and inhibition of lymphocyte proliferation and function. The purposes of this study were to characterize alterations in inflammatory mediator production, and lymphocyte proliferation, in dogs fed a diet consisting of 0.65% n-3 fatty acids (DMB) with an n-6:n-3 fatty acid ratio of 3.4:1. Fifteen dogs were randomly assigned to one of three dietary groups for twelve weeks. Group Sunflower oil received …
The Effects Of Intra-Articular Silicone Polymer On Synovial Fluid, Synovial Tissue, And Articular Cartilage In The Equine Middle Carpal Joint, Marilyn Rumbaugh
The Effects Of Intra-Articular Silicone Polymer On Synovial Fluid, Synovial Tissue, And Articular Cartilage In The Equine Middle Carpal Joint, Marilyn Rumbaugh
LSU Master's Theses
There is anecdotal documentation that intra-articular administration of liquid silicone is used as a lubricant for equine joints. Effects of silicone polymer on equine articular cartilage and synovial fluid have not been evaluated. The objectives were to characterize the effects of intra-articular administration of liquid silicone polymer on clinical, synovial fluid, and microscopic features in normal middle carpal joints of horses, and to determine if silicone migrates to the axillary lymph nodes. Eight adult horses were used in this study. Two mLs of 1,000 centistoke, medical-grade silicone was injected into one randomly selected middle carpal joint. The opposite middle carpal …
Six-Month Follow-Up Of A Primary Care Managed Weight Loss Program For Overweight And Obese African-American Women, Lee A. Marsh
Six-Month Follow-Up Of A Primary Care Managed Weight Loss Program For Overweight And Obese African-American Women, Lee A. Marsh
LSU Master's Theses
Obesity is the number one public health concern in the United States, and is more prevalent in African-American women and those from lower socioeconomic groups. However, many primary care physicians do not feel confident in their ability to assist patients in weight management. Thus the challenge for physicians is to provide patients better assistance with weight management. The purpose of the study was to examine the efficacy of a primary care-managed weight loss program on weight reduction and cardiovascular fitness in overweight/obese women. Participants were randomized to intervention (n=54; Age: 44+12 yrs) or standard care (n=62; Age: 44=12yrs) and followed …
The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich
The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich
LSU Master's Theses
Vaccination programs are designed to protect an animal from infection, however, depending upon the age and health of the animal vaccination may not stimulate a protective humoral response. It is possible that, as in the human and mouse models, geriatric equines may be less responsive than their younger counterparts to current vaccination protocols. The purpose of this study was to identify an age related diminution in the primary and secondary immune responses of geriatric horses in response to vaccination. Two groups of horses were sampled. The first group consisted of an open herd of 39 privately owned horses, varying in …
Psychosocial Predictors Of Visceral Adiposity, Paula C. Rhode
Psychosocial Predictors Of Visceral Adiposity, Paula C. Rhode
LSU Doctoral Dissertations
Psychosocial factors are thought to influence health through primarily direct physiological mechanisms or the alteration of health related behaviors. Three factors hypothesized to negatively impact health include arousal, life stress, and depressive symptomatology. One recent theorist suggests that the interaction between psychological stress and stress hormones on the neuroendocrine system may result in adverse changes to body composition, most notably the increased deposition of visceral adipose tissue (Bjorntorp, 1993). The current study prospectively examined the relationship between self-reported stressful life events, depressive symptoms and trait arousal on the deposition of visceral fat, as measured by computerized tomography (CT). Subjects were …
Proportional Assessment Of X And Y Chromosome-Bearing Spermatozoa In Bull And Boar Ejaculates Using Conventional And Real-Time Pcr Techniques, Julius Braden Paul
Proportional Assessment Of X And Y Chromosome-Bearing Spermatozoa In Bull And Boar Ejaculates Using Conventional And Real-Time Pcr Techniques, Julius Braden Paul
LSU Doctoral Dissertations
Considerable variation in the percentage of Y-chromosome bearing spermatozoa (%Y-CBS) between ejaculates in the same male has been reported. Collection regime has been speculated to influence the degree of variation in %Y-CBS in bull ejaculates (Chandler et al., 1998). Experiments were designed to evaluate the effects of two collection regimes on %Y-CBS. Conventional PCR combined with gel electrophoresis and image analysis was employed to determine %Y-CBS in ejaculates from two bulls collected on 7-day intervals and two bulls on 21-day intervals. Real-time PCR technology was used to quantify %Y-CBS in the same ejaculates. Boar ejaculates were also analyzed with both …

Mediators Of Weight Loss In An Internet-Based Intervention For African American Adolescent Girls, Marney A. White
LSU Doctoral Dissertations
The primary aim of this study was to assess the process variables involved in a weight loss program for African-American adolescent girls. This internet-based intervention compared a behavioral treatment program to an educational treatment program; it was hypothesized that participants randomized to the behavioral condition would lose more weight at 6 months than those in the educational condition. Several process variables have been identified as affecting success in in vivo weight loss programs for adults and children, including program adherence, self-efficacy, and social support. The current study sought to broaden the understanding of these process variables as they pertain to …

Optimization And Automation Of A Thermal Oyster Shucking Process, Daniel Edgar Martin
LSU Doctoral Dissertations
Louisiana Gulf Coast oysters (Crassostrea virginica) were subjected to thermal shucking treatments to effect adductor muscle release from both left and right valves. The oysters were instrumented with thermocouples to monitor and record process temperatures in the oysters and on the shell. Following treatment, the oysters were evaluated for relaxation and release of the adductor muscle, meat quality and texture, and for the effect of the treatments on the storage life of the oysters as measured by total microbial plate counts. The treatments of many oysters resulted in a complete release of the adductor muscle from the shell while maintaining …
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
LSU Doctoral Dissertations
Children’s physical inactivity is becoming an important health concern, and it has been suggested by professionals that school programs can be important in the effort to increase activity levels. Physical education specialists cannot achieve the goal of significantly increasing children’s activity in isolation, and it is apparent that whole school programs at the elementary level have the potential to foster active lifestyles. If those programs are to be successful, all school personnel must play a role, so it is important to find ways to facilitate their involvement. The purpose of this study was to use collective efficacy as a framework …
A Path Analysis Of Binge Eating And Obesity In African Americans: Acculturation, Racism, Emotional Distress, Binge Eating, Body Dissatisfaction, Attitudes Towards Obesity, Dietary Restraint, Dietary Fat Intake, And Physical Activity, Joy Rose Kohlmaier
LSU Doctoral Dissertations
The purpose of this study was to test a general stress-related health behavior model as it applied to binge eating and obesity in African Americans using path analysis. Acculturation, racism, emotional distress, binge eating, and obesity were among the variables related to this theory, and included in the model. Other variables that have been implicated in the study of obesity in African Americans were also included, such as; lack of body dissatisfaction, accepting attitudes towards obesity, decreased dietary restraint, increased dietary fat intake and decreased physical activity. The study sample was 325 African Americans, including 187 females with a mean …
Adherence To Medical Regimens In Low-Income Adults With Type 2 Diabetes: The Influence Of Perceived Control Constructs, Erin L. O'Hea
Adherence To Medical Regimens In Low-Income Adults With Type 2 Diabetes: The Influence Of Perceived Control Constructs, Erin L. O'Hea
LSU Doctoral Dissertations
Individuals with Type 2 diabetes often do not adhere to their treatment regimens (e.g., exercise, diet, medication, glucose monitoring). Non-adherence results in poor metabolic control, further morbidity and mortality, and increased health care utilization and costs. One common thread among many health-behavior-theories that attempt to explain non-adherence behaviors is the importance of perceived control. This psychosocial variable has most often been conceptualized as ‘health locus of control,’ which refers to the belief that one has the ability to influence or change one’s health outcomes. Inconsistent findings have been reported regarding the relationship of health locus of control and medical regimen …
Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi
Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi
LSU Master's Theses
Age is associated with deterioration in physical function (PF) and health-related quality of life (HRQL). Recent investigations suggest that a decrease in function may have a greater impact on perceived activities of daily living (ADL) competency in women than in men. The purpose of this investigation was to test the hypothesis that the association between PF and HRQL among older adults is influenced by gender. We examined 108 older adults aged 60 years or older, for PF (Continuous Scale-Physical Function Performance test (CS-PFP10) and Functional Status Index (FSI)) and HRQL (SF-36). In order to address this question we assigned subjects …
Barriers To Adherence In A Free Medication Program For Low Income Individual With Type 2 Diabetes, Bhrett A. Mccabe
Barriers To Adherence In A Free Medication Program For Low Income Individual With Type 2 Diabetes, Bhrett A. Mccabe
LSU Doctoral Dissertations
Diabetes self-management and treatment require significant patient involvement to maintain appropriate glucose control. Glucose control is directly related to adherence to a variety of regimens, of which medication adherence may be most important. Unfortunately, adherence to these regimens has been quite poor. Among low income patients, the strongest reason given for medication nonadherence has been the cost associated with purchasing medication. In 1999, the Louisiana State University Health Care Services Division instituted a free medication program for low income individuals with chronic illnesses, including diabetes. Despite removing this strongest barrier to adherence among low income patients, initial data from this …

Use Of Primary Production By Benthic Invertebrates In A Louisiana Salt-Marsh Food Web, Padma Maddi
LSU Master's Theses
A combination of natural abundances of stable carbon and nitrogen isotopes and tracer-addition experiments were employed to determine the relative contributions of three potential food sources (phytoplankton, benthic microalgae, and Spartina alterniflora) to benthic invertebrate fauna of Louisiana salt marshes. Samples of the major food sources and the consumers were collected quarterly (summer, fall, winter and spring) to analyze the ƒÔ13C and ƒÔ15N ratios. A simultaneous tracer-addition experiment, in which benthic microalgae (BMA) were labeled with NaH13CO3 and 15NH4Cl, was conducted in all quarters to determine the relative importance of the BMA to consumers. Results indicated that the carbon isotopic …

Municipal landfill leachate contains high levels of metal species, including Cu, Zn, Cd and Pb generating competitive interactions between these metal species and the landfill clay liner materials. Characterization of the clay fraction, physical and chemical characteristics of landfill clay liner materials, the competitive interaction of metal species with clay liner materials, the kinetic modeling of metal species transport in clay liner, and the effect of cyclic interfacial redox potential on the structural changes to the clay liner and leachate metal transport were investigated in this study. The clay liner materials studied included Na-bentonite, kaolinite and Amite soil (sandy silty …
Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar
Numerical Solution Of Ocular Fluid Dynamics, Satish Kumar
LSU Master's Theses
Numerical calculations of the aqueous humor dynamics in the anterior chamber of both the rabbit and the human eye are presented to delineate the basic flow and transport mechanisms. The calculations are based on a geometrical model of the eye, which represents the Trabecular mesh (TM) as a multi-layered porous zone of specified pore sizes and void fraction. Buoyancy is observed to be the dominant driving mechanism for the convective motion in both orientations (horizontal and vertical) of the eye. Reducing the TM pore size does not appear to have a significant influence on the intra-ocular pressure (IOP) until the …

Metabolic Aspects Of Oryzanol In Rats, Michelle Smith Gillespie
LSU Master's Theses
Using a rat model, this study compared the bioavailability of three forms of oryzanol, a compound extracted from rice bran oil that has been associated with improved cholesterol levels. Various methods of extracting lipids from serum and liver were explored to determine oryzanol absorption. Cholesterol levels were obtained via enzymatic colorimetric assay and GCMS. Sprague Dawley retired female breeder rats were sustained for 11 weeks on a cholesterol-free diet to which either no oryzanol was added (n = 19) or 2.8 g/kg of oryzanol was added as: 7% oryzanol rice bran oil (RO, n = 8), crystalline oryzanol (CO, n …
