Beta Galactosidose Activity Of Commercial Lactase Samples In Raw And Pasteurized Milk At Refrigerated Temperatures, Trenton W. Horner

Theses and Dissertations

Many consumers are unable to enjoy the benefits of milk, due to lactose-intolerance. Lactose-free milk is available, but at about 2 times the cost of regular milk or greater, it may be difficult for consumers to afford. The high cost of lactose-free milk is in part due to the added cost of the lactose hydrolysis process. Hydrolysis at refrigerated temperatures, possibly in the bulk tank or package, could increase the flexibility of the process, and potentially reduce the cost. A rapid β-galactosidase assay was used to determine the relative activity of commercially available lactase samples at different temperatures. Four enzymes …

Theses and Dissertations

The purpose of this study was to conduct an analysis on ex post facto data of the federal grant supported Homeless Veterans Reintegration Program (HVRP) administered at Goodwill Industries of Lower South Carolina. Pre-existing data on variables such as performance goals, training activities, support services, and demographics from program years 2006-2008 were used as data sources for the study. A descriptive statistics method of program analysis was employed and results were used to determine if performance outcomes met initial performance goals. The results from the study revealed that in order to successfully reintegrate into the workforce, HVRP participants required basic …

Accuracy Of Estimating Age And Antler Size Of Photographed Deer, Jeremy J. Flinn

Theses and Dissertations

Objective and accurate techniques are needed to estimate age and antler size of live white-tailed deer (Odocoileus virginianus), because these parameters are essential to many white-tailed deer management strategies. I developed and evaluated accuracy of methods for estimating age and antler size from photographs of live, male white-tailed deer using Geographic Information Systems (GIS). I estimated size of photographed, known-score mounted antlers accurately using a fixed-scale object and photographed, live deer using anatomical features. I determined if a series of morphometric ratios could be used to predict age of deer from photographs using a dichotomous key procedure. Mean percentage error …

Characterization Of Arabidopsis Thaliana Mutants Lacking A Jumonji Domain Containing Histone Demethylase And A Set Domain Containing Histone Methyl Transferase, Swetha Mamidi Reddy

Theses and Dissertations

Condensation of chromatin and alteration of chemical groups in the proteins around which the DNA is wrapped play major role in regulation of transcription. Histones are basic proteins rich in arginine and lysine residues which form the nucleosomal core. Histone modifications like acetylation, methylation, phosphorylation, etc. have broadened the horizon for researchers to study epigenetics more in detail. Histone methyl transferases and histone demethyl transferases are enzymes which add or remove methyl groups on histone lysine and arginine residues respectively. In this study a jumonji domain containing putative histone demethyltransferase has been shown to be responsible in controlling flowering phenotype …

The Effects Of Dietary Amino Acid Density In Broiler Feed On Carcass Characteristics And Meat Quality, Reid Alexander Lilly

Theses and Dissertations

Research was conducted to evaluate the effect of dietary amino acid (AA) density (Deficient (D), Low (L), High (H), and Excessive (E)) on broiler breast and thigh meat quality. As expected, the feed conversion improved (P<0.05) as AA density increased. No differences (P>0.05) existed among treatments with regard to final pH, cooking loss, shear force, brine absorption proximate analysis, and average consumer acceptability of breast meat. The D AA diet yielded meat with less (P<0.05) moisture, less protein (P<0.05) and more fat (P<0.05) than all other treatments. Increasing AA density in the diet led to increased (P<0.05) concentrations of linoleic and linolenic acid in the thigh meat from the H and E treatments, thus making it more susceptible to oxidation (P<0.05) in comparison to the D and L treatments. Overall, data revealed that all four AA diets yielded high-quality breast and thigh meat with minimal product differences.

Nutrient Utilization By And Diet Preference Of American White Pelicans When Offered Diets Of Channel Catfish And (Or) Grass Carp, Treena Lee Ferguson

Theses and Dissertations

Twelve pelicans captured in northeast Mississippi were used for a 7 day metabolism trial followed by a 2 day preference trial and a trial to evaluate the effect of consuming plastic tags. In the metabolism trial, pelicans were allotted to one of three treatment diets (4 birds/diet): catfish only, carp only or both (50 % catfish and 50% carp). Pelicans consuming the catfish only diet metabolized less dry matter, organic matter and energy than those consuming only carp or both. Four pelicans were used to determine preference for carp or catfish. Pelicans ate more (P = 0.001) carp (89 % …

Depuration As A Method To Reduce Vibrio Vulnificus Populations In Live Crassostrea Virginica Oysters, Oleksandr S. Tokarskyy

Theses and Dissertations

Vibrio vulnificus is a foodborne bacterial pathogen associated with raw oyster consumption. Shellfish depuration for 48 hours is a dynamic process where coliform bacteria are purged; however, this process is ineffective against V. vulnificus. The current study investigated the use of prolonged two-week depuration on V. vulnificus populations in Gulf Coast oysters. The study evaluated the impact of prolonged depuration on V. vulnificus fatty acid profile change and the ability to survive in simulated gastric fluid. Oyster depuration in seawater (10 or 22oC, 14 days) reduced V. vulnificus counts, but not to non-detectable level, indicating close ecological relationship between the …

Effects Of Trinexapac-Ethyl On Ornamental Grass Species, Alvin Scott May

Theses and Dissertations

Studies were conducted to evaluate the effects of trinexapac-ethyl (TE) on height reduction, tillering, chlorophyll content, color, flowering, and root development of three ornamental grasses: Calamagrostis ×acutiflora 'Karl Foerster', Miscanthus sinensis 'Variegatus', and Pennisetum ×advena 'Rubrum'. Two applications of TE reduced height in all grasses and improved chlorophyll content in C. 'Karl Foerster' while delaying flowering in M. 'Variegatus' and P. 'Rubrum'. Tillering was slightly increased in M. 'Variegatus' with two TE applications. Shoot dry weight (SDW) and root dry weight (RDW) were reduced in C. 'Karl Foerster', SDW was reduced in P. 'Rubrum' and SDW and RDW were unaffected …

In Vivo Comparison Of Edwardsiella Ictaluri Survival In Kidneys Of Vaccinated And Naïve Rag1-/- Zebrafish, Casey Janine Varner

Theses and Dissertations

This study used rag1-/- mutant zebrafish, which lack functional T and B lymphocytes, to investigate whether innate immune cells from vaccinated mutant zebrafish demonstrate enhanced survival compared to phagocytes from naïve mutant fish. Edwardsiella ictaluri, an economically significant aquatic pathogen and the causative agent of enteric septicemia of catfish (ESC), was used for the trials. Quantification of live bacteria from sampled kidneys was accomplished via colony counts, luminescence readings, and differential DNA extractions using Ethidium Monoazide (EMA) and Propidium Monoazide (PMA) followed by qPCR. There was a general trend of less bacteria in vaccinated mutant fish. Additionally, the mortality in …

Mode Of Action And Characterization Of A Novel Biological Response Modifier Isolated From Fractionated Caprine Serum, Charles Joseph Matyi

Theses and Dissertations

Immune Cell Potentiating Factor (ICPF) represents a class of biological response modifiers initially only found within active caprine serum fractions. Controlled studies have since demonstrated active ICPF derived from several non-caprine mammalian sources; including equine and human. ICPF is able to increase survivability in murine gram negative induced sepsis (60%) as well as secondary infection and subsequent sepsis in canines infected within canine parvo virus 2 (36%) despite showing no innate antiviral properties. ICPF is able to initiate systemic proteomic changes within several organ systems; including serum, liver, brain, lung, and spleen. ICPF initiated an early acute phase response, specifically …

Fire Ant Response To Management Of Native Grass Field Buffers, Sarah Lucinda Hale

Theses and Dissertations

Imported fire ants are invasive and cause injury to people, crops, livestock and wildlife. Disturbance may increase abundance and activity of fire ants. However, native grass field buffers established for grassland birds require periodic disturbance. I experimentally tested if fire ant mound density and foraging activity changed after burning and disking in native grass buffers and examined relationships among fire ants, vegetation, and grassland bird and butterfly metrics in undisturbed buffers. In 2008, disking increased mound density and foraging activity, but burning did not. In 2009, disking had no effect, but effects of disking the previous season persisted. Fire ant …

Factors Affecting Ammonia Volatilization From Broiler Litter, Dana Mcgee Miles

Theses and Dissertations

Loss of ammonia from broiler litter degrades air quality, decreases litter fertilizer value, and can have negative health consequences for birds and their caretakers. Rates of NH3 emission from broiler houses are complicated by interrelated management and environmental factors such as air temperature, humidity, house style, ventilation rate,bird age, litter conditions, litter characteristics, and cleanout schedule. Wide variations inemission rates necessitate further investigation of litter characteristics and abatement techniques. The research was designed to clarify the impact of moisture effects that are critical to emissions for poultry litter, in conjunction with bedding type and temperature. Experiments were conducted on litter …

Factors Affecting Morphometrics And Epiphyseal Closure Of White-Tailed Deer, Emily Brooke Flinn

Theses and Dissertations

Factors affecting morphometrics and epiphyseal closure are important in understanding regional variation and growth of white-tailed deer (Odocoileus virginianus). I compared body and antler growth from birth to 3 years of age in captive, first-generation, male white-tailed deer from three regions with varying soil quality and deer morphometrics. I also determined gender and age effects on epiphyseal closure timing in captive white-tailed deer. I found regional morphological variation present in first-generation male deer, which may be caused by regional genetic variation or lingering maternal effects. Determining cause of regional morphological variation will require data collection through a second-generation of males …

Travel, Migration And Hiv:Comparing Risk Behaviors Betweennative And Migrant Jamaican Persons Infected With Hiv, Yoran T. Grant

Open Access Dissertations

Migration and travel have been significant factors in the human immunodeficiency virus (HIV) epidemic since its emergence in 1981. Understanding the current effects of migration and travel on HIV/AIDS transmission and survival is essential to intervention efforts, especially for immigrants. Previous research highlights differences between immigrants and native ethnic minorities, but few studies compare immigrant groups to their peers in the country of origin. The overall objective of this study was to explore the relationship between migration, travel and risk behavior among Jamaicans infected with HIV. This dissertation study analyzed HIV/AIDS registry data from the New York City Department of …

Consistency Of Written Trauma Narratives Over A Course Of Trauma-Focused Therapy, Juliette Marissa Mott

Dissertations

Several of the procedures commonly used in trauma-focused therapies are similar to techniques that have been shown to influence the consistency and accuracy of memory in experimental settings. These techniques include verbalizing a non-verbal memory, repeatedly recalling an event, and recalling an event in the presence of another person. In an effort to examine the impact of such techniques on memory for a traumatic event, and in turn the impact of traumatic memory change on treatment outcome, the present study examined changes in written trauma narratives created over the course of trauma-focused therapy. Participants were PTSD-positive female survivors of interpersonal …

Sleep, Bmi, And Work-Family Conflict: A Gender Comparison Of U.S. Workers, Blake Lee Jones

Theses and Dissertations

This study used structural equation modeling (SEM) to examine how sleep problems, Body Mass Index (BMI), and poverty were related to several work, personal, and family variables in a sample of married male and female workers in the United States. The data for this study came from the National Study of the Changing Workforce (NSCW) 2008. This large, nationally representative dataset provided a resource for examining potential gender differences in variables that have been linked to sleep problems and increases in BMI, as well as how each of these variables relate to several work, personal, and family life outcomes, including …

Assessing School Neighborhood Walkability: A Targeted Approach To Safe Routes To School Programming, Chelsea O. Shelling

LSU New Orleans Theses and Dissertations

This thesis intends to demonstrate how capital infrastructure investments can be targeted objectively, using the "Safe Routes to School" (SRTS) program for context. SRTS impacts physical activity, a determinant of childhood obesity by encouraging children’s regular active transportation use. This thesis supports the widespread implementation of SRTS and has developed the "Shelling Model" to objectively identify schools for programming. Accordingly, the "Shelling Model" aims to objectively identify physical and socio-economic environment variables impacting HISD-E middle school neighborhoods’ walkability. The "Shelling Model" is a first step in creating a walkability index for which pedestrian orientation levels can be identified and schools …

The Interaction Of Pain And Morphine On Analgesia, Locomotion, And Cognitive Functioning, Brandon Baiamonte

LSU New Orleans Theses and Dissertations

Opioid medications are medicine's best weapon against severe intractable pain, but prolonged use of these medications can be complicated by side effects like tolerance and mental clouding which, themselves, can be disabling. The present study examined the independent and combined effects of inflammatory pain and opioid medication on spatial memory for a well learned task in Sprague-Dawley rats. The Hargreaves method was used to verify the pain state of the animals after complete Freund's adjuvant injection and morphine treatment. Whereas pain had little effect on spatial memory, morphine had profound detrimental effects that persisted beyond the analgesic effectiveness of the …

Toward A Theory Of Female Subjectivity, Dimitra Cupo

LSU New Orleans Theses and Dissertations

Poststructuralist accounts of gender provide a useful theoretical space to unpack the workings of power and domination as they structure the organization of our language, representations, concepts, and discourse in general. One significant flaw of this theory is a failure to adequately account for the social realm of embodied individuals, social interactions, and interpretive moments. In this paper, I offer conventional femininity as a particular type of gendered habitus that highlights this theoretical flaw as it necessarily links what is promising and useful about poststructuralist accounts of gender with the physical, social, interactive, and interpretive everyday lives of women.

The Effect Of Resistance Training On Strength And Total Physical Activity In Postpartum Females, Tiffany Kaye Hinman

Theses and Dissertations

The purpose of this study was to compare strength and physical activity (PA) changes in postpartum women randomly assigned to either a four-month progressive resistance training (RT) program or a four month flexibility program. Sixty healthy women between six weeks and eight months postpartum initiated the study and 43 completed the entire study. The women tended to be overweight, were all non-smokers, and most were breastfeeding (97%) at the beginning of the study. Both groups (RT and flexibility) completed training exercises twice weekly. Both groups improved in all measures of strength (RT group: leg press, P < 0.001; bench press, P < 0.001; curl-ups, P < 0.001. Flexibility group: leg press, P = 0.009; bench press, P < 0.001; curl-ups, P = 0.005); however, the RT group had higher strength gains compared to the flexibility group over time (leg press, P < 0.005; bench press, P < 0.001; curl-ups, P < 0.007). In addition, both groups increased in low back flexibility but the group*period interaction did not reach significance (P = 0.096). Light-intensity PA increased in the RT group but not the flexibility group (P < 0.05). A group*period interaction was significant for light-intensity PA time (P = 0.031) and borderline significant for sedentary time (P = 0.054). However, controlling for the number of months postpartum and weight gain during the previous pregnancy resulted in a significant interaction for sedentary time (P < 0.05). No changes were found in moderate, vigorous, or moderate to vigorous PA within or between groups over time. In conclusion, twice-weekly RT increases strength and is associated with improvements in several PA outcomes in postpartum women; however, the mechanisms for this are unclear. The training sessions and/or increased spontaneous activity may have contributed.

Antibiotic Resistance In Bacillus Subtilis As Affected By Transcriptional Derepression And The Stringent Response, Brandon Eisinger, Ronald E. Yasbin, Eduardo A. Robleto

Undergraduate Research Opportunities Program (UROP)

Bacterial cells under conditions of starvation or prolonged non-lethal selective pressures accumulate mutations in highly transcribed genes. This process is part of cellular programs to increase genetic diversity in conditions of stress, also known as stationary phase or stress-induced mutagenesis. This experiment investigated mutation frequencies for antibiotic resistance as affected by the stringent response. The stringent response is a global cellular process that initiates at the cessation of growth and mediates changes in gene expression that repress synthesis of ribosome components. We used Bacillus subtilis strains that differ in RelA proficiency. The relA gene controls the synthesis of (p)ppGpp, the …
