The generation of natural compounds with these properties is of special interest to the food industry. The objective of this study was to develop and characterize CSH including antioxidant and antimicrobial properties. CSH were produced from different enzymatic reaction periods using alkaline protease, and their characterization, antioxidant, antimicrobial, and some functional properties were evaluated. A selected CSH was analyzed for peptide composition and partial amino acid sequences. The color analysis showed that darker, more yellow, and …

Influence Of Silicon On The Development Of Anthracnose Of Grain Sorghum, Sanjay Pokhrel

LSU Master's Theses

To study the effect of Silicon (Si) with and without a fungicide on anthracnose development of sorghum, several experiments were conducted in the greenhouse and field. In the initial study, different Si rates [0 (control), 0 (lime control), 200, 400, 600, 800 kg Si/ha] were used in a low-Si Alfisol to determine if inoculum densities were affected by Si levels. No differences were observed between inoculum densities of 1*105 and 1*106 conidia/ml in affecting anthracnose development in the greenhouse. Anthracnose severity was found to be lowest in plants treated with 800 kg Si/ha, regardless of inoculum density. In another study, …

The Evaluation Of Eprinomectin (Longrange®) On Long-Term Parasitic Infection In Nursing Calves During Summer Grazing®, Lyndsea D. Seibert

LSU Master's Theses

One of the most significant threats to the well-being and performance of grazing livestock are gastrointestinal nematode (GIN) parasitic infections. Allowing a large GIN burden to manifest can cause a significant cost in terms of productivity in grazing cattle. Beef producers commonly rely greatly on the efficacy of broad-spectrum anthelmintics, to not only kill resident worms but to also prevent the establishment of ingested infective stage larvae (L3) for a period following treatment. Eprinomectin (LONGRANGE®, E-LR) is the first extended-release injectable cattle dewormer that claims to provide cattle producers season-long persistent parasite control for 100 to 150 d in a …

The Economic Burden Of Gluten-Free Products And The Potential Of Dietary Inhibitors Of Transglutaminase-2, Kristen Kramer

LSU Master's Theses

Celiac disease (CD) is a chronic immune-mediated disease of the small intestine caused by the ingestion of gluten. Gluten presents to the intestine largely intact where it is deamidated by Transglutaminase-2 (TG2), increasing affinity for Human Leukocyte Antigen DQ2 (HLA-DQ2) and forming a complex that elicits an inflammatory response ultimately leading to villous atrophy. The only current treatment is strict adherence to a gluten-free diet, though TG2 inhibition is an attractive therapy due its central role in CD pathogenesis. Cocoa contains procyanidin-B2, theobromine and caffeine and may be capable of inhibiting TG2-induced intestinal inflammation and reduce CD symptoms. Procyanidin-B2 rich …

Microfluidic Device For Motility And Osmolality Analysis Of Zebrafish Sperm, Jacob Ethan Beckham

LSU Master's Theses

An increasing number of laboratories are evaluating sample quality via motility analysis by means of computer-assisted sperm analysis (CASA) after sperm activation by manual dilution and mixing. Even with the use of CASA, due to user variation, there is a lack of control over the activation process, resulting in inconsistent motility analysis. Low sample volume (~1-2µL), and a short motility duration (burst motility of less than 15s) add to the complexity of these difficulties. The objectives of this study were to develop a microfluidic device with the capabilities to (1) standardize the method of activation for zebrafish sperm so that …

The Role Of Nadph Oxidase 2 (Nox2) In High-Fat Diet-Induced Adiposopathy And Brain Dysfunction In A Mouse Model, Jennifer Kathleen Pepping

LSU Master's Theses

Obesity can have numerous detrimental consequences, namely metabolic syndrome, type 2 diabetes, cardiovascular disease, cancer, and Alzheimer’s disease. The pathogenesis and physiologic consequences of obesity are unknown, but they are often associated with increased inflammation and oxidative stress in both the body and in the brain. One factor that has been implicated in causing inflammation associated with a high fat diet is the enzyme NADPH oxidase, or NOX, specifically the subunit NOX2. Two studies were performed in order to assess the effects of a high fat diet in combination with a universal NOX2 deficiency and a NOX2 deficiency targeted to …

The Effect Of Artificial Light On The Community Structure And Distribution Of Reef-Associated Fishes At Oil And Gas Platforms In The Northern Gulf Of Mexico, Victoria Anne Barker

LSU Master's Theses

The northern Gulf of Mexico (GOM) contains approximately 2,500 oil and gas platforms, resulting in one of the largest de facto artificial reef systems in the world. As of 2013, 1,227 additional structures had ceased to produce oil and gas and have been decommissioned and removed. While active platforms are lit by high-pressure mercury vapor lights, inactive platforms are only minimally lit for navigation. The positively phototaxic behavior of many fish species causes lit oil platforms to act as fish attraction devices, especially at night. Though a variety of fish species have been reported near these structures, changes in fish …

Effect Of Bitterness Blockers In Partial And Complete Replacement Of Sodium Chloride With Potassium Chloride On The Physicochemical And Sensory Characteristics Of Marinated Chicken Breast Fillets, Ana Gabriela Ocampo Arriaga

LSU Master's Theses

High sodium intake has negative health implications on hypertension and cardiovascular diseases. Brines used in chicken marination are composed of salt (NaCl), phosphates and seasonings. Potassium chloride (KCl) is the most common sodium replacer but its use is typically limited to less than 50% substitution due to its undesirable bitterness and metallic aftertaste. The objective of this study was to determine the effect of 5’ adenosine monophosphate (AMP) and glycine, as bitterness blockers, on physicochemical, sensory characteristics and purchase intent of sodium reduced chicken breast fillets. Chicken breast was injected with a 20% pick-up solution. Salt treatments (trts) were 50, …

Evaluation Of Alkaline- And Fungal-Assisted Wet Storage Of Energycane Bagasse, Jing Cao

LSU Master's Theses

Lignocellulosic biomass is a promising renewable resource for the production of biofuels and biochemicals. Energycane is considered a lignocellulosic biomass characterized by its high fiber content and cold tolerance. It can be planted on marginal land and does not need to compete with the food supply. Wet storage in combination with sodium hydroxide (NaOH) or white-rot fungi was applied to energycane bagasse to preserve the lignocellulosic polymeric sugars (cellulose and hemicellulose) during short-term storage (60 days) and to make them accessible for conversion into biofuels and biochemicals. Alkaline-assisted wet storage was successful in preserving the biomass by minimizing microbial degradation, …

Metric Variation In The Human Sacrum: Costal Process Length Among Black And White South Africans, Christy Rose Wayne

LSU Master's Theses

Considerable attention has been given to the measureable differences that exist between different human populations in the size and shape of the pelvis, with Africans having a narrower pelvis than Europeans. By collecting data on sacral breadth from a South African skeletal population, this study (1) tests the hypothesis that African blacks possess a narrower sacrum, and by inference pelvis, than whites and (2) considers whether the size variation between blacks and whites is due to nutritional, historical and social differences, to a genetic basis related to climatic adaptation, or to both. White South Africans were found to possess a …

Health Benefit Statements Affect Consumer Liking, Emotions, And Purchase Intent: A Case Of Gluten-Free, Sugar Reduced Banana Muffins, Amber Renee Jack

LSU Master's Theses

Product information given to consumers can be used to improve food choices; however, consumers may respond differently depending on the given information. Nutritional information can serve as an instrument to positively influence healthier food choices and purchase intent. The market for gluten-free products reached $5.5 billion in 2015; however, there is a need for development of acceptable gluten-free and sugar-free products driven by consumers who are nowadays more health conscious. Muffin, a high calorie baked-good product, is very popular among consumers and known for its pleasant aroma and sweet taste qualities. There are a number of commercial gluten-free muffin products, …

Testing Fitness-Related Phone Application Technology In Physical Activity Classes, Angela Nicole Simonton

LSU Master's Theses

Many young adults are inactive (Centers for Disease Control and Prevention, 2010) and time spent on smartphones and applications (“apps”) is high (Pew Research Center, 2014; The Nielsen Company, 2014). Technology is often viewed as a barrier to health behavior, so seeking ways of using technology to facilitate physical activity (PA) and other health-related behaviors could be beneficial. The Social Cognitive Theory (SCT) framework was used to determine if the NexTrack smartphone app could increase PA behaviors and SCT-related constructs among university students in PA courses. Participants in the NexTrack app intervention group were hypothesized to report increased psychosocial and …

Here, we present a comprehensive, structured, and transparent conceptual framework of human wellbeing designed to guide the development of indicators and a complementary social science research agenda for ecosystem-based management. Our framework grew out of an effort to develop social indicators for an integrated ecosystem assessment (IEA) of the California Current large marine ecosystem. Drawing from scholarship in international development, anthropology, geography, …

Maternal Mortality: A Policy Comparison Between Nigeria And India., Rachel Quarles

Dissertations and Theses

A staggering number of women die from preventable deaths each year from causes related to pregnancy and childbirth. India hosts the greatest number of actual maternal deaths in the world, although Nigeria’s ratio of maternal deaths to live births is greater than India’s. This thesis focuses on the experience of these two countries in order to determine if India’s governmental policies, level of government corruption, and traditional practices directly lead to its comparably better maternal health statistics. India has demonstrated lower ratios of maternal mortality and more consistent improvement in maternal health indicators than Nigeria as a result of stronger …

Are We Fulfilling The Promise Of A Jesuit Education? A Group Of Educators’ Reflective Examen, Kenneth S. Sagendorf, Susan A. Scherer, James D. Nash, Dirk J. Dunfee S.J., Cheryl Schwartz

Jesuit Higher Education: A Journal

Higher education is often faced with external pressures that can guide the practice and offerings of colleges and universities. Graduate professional education in the health professions is especially prone to accreditation standards and its associated professional movements. At a Jesuit university, these external pressures, along with public pressure for job-ready graduates, must be intertwined with the history and the promise of a Jesuit education — that of transformation. As educators at a Jesuit university, our roles involve more than offering this kind of education. Our responsibility is to revisit what this promise means as a way of examining our practice. …
