Engineering Yeast To Evaluate Human Proteins Involved In Selective Rna Packaging During Hiv Particle Production, Ryan M. Bitter

Master's Theses

Despite recent advances in antiretroviral therapy, nearly 37 million people continue to live with human immunodeficiency virus (HIV). Basic and applied research on the assembly of HIV could be enhanced by using a genetically tractable organism, such as yeast, rather than mammalian cells. While previous studies showed that expression of the HIV Gag polyprotein in Saccharomyces cerevisiae spheroplasts resulted in the production of virus-like particles (VLPs), many questions regarding the utility of yeast in HIV assembly remain uninvestigated. Here, we report use of S. cerevisiae for both the production of VLPs with selectively packaged RNA and to evaluate the human …

Presence Of Antibiotic Resistant Salmonella Spp. In Backyard Poultry And Their Environment, Nicole Land

Master's Theses

As keeping backyard poultry rises, human contact with zoonotic pathogens will increase. One such pathogen that backyard enthusiasts have exposure risks to is Salmonella spp. which may cause a potential public health threat due to its increasing multidrug resistancy. Salmonella spp. were present in 33 of 50 samples collected from 29 sites with backyard poultry coops in San Luis Obispo County during March to May in 2014. Two different Hardy-CHROME™ Salmonella Selective Media plates were used to culture and isolate positive samples of Salmonella spp.. Each positive isolate was tested for antimicrobial sensitivity to 6 standard antibiotics: Ampicillin, Bacitracin, …

Comparative Analysis Of Body Composition And Reference Values Of Visceral Adipose Tissues In Various American Collegiate Sports, Eshan M. Dandekar

Master's Theses

Background: Currently, body composition (BC) assessment is usually performed to diagnose disease states and accurately estimate certain types of tissues. In athletes, performing BC assessments helps gauge training and nutrition programs to see if they are adequately meeting the athlete’s needs to improve performance. Annual Dual Energy X-ray Absorptiometry (DXA) scans before the start of an athlete’s season can help identify an athlete’s preparedness or health before training begins.

Objective: To assess the preseason BC of four collegiate sports: Men’s basketball, men’s baseball, women’s volleyball, and women’s soccer, for Fat Mass (FM), bone mineral density BMD), Fat-Free Mass …

Detecting A Probiotic Product Within The Gut Of Broiler Chickens, Anneka Pisula

Master's Theses

As of January 2017, the U.S. poultry industry banned the use of antibiotics and now relies on alternatives such as probiotics to help protect animal health. Although probiotic use is not a new concept in the poultry industry, identifying the best combination of bacterial strains to generate an effective probiotic formula requires further investigation. This study aimed to detect a probiotic product of four bacterial strains (Pedioccoccus acidilactici, Pediococcus pentosaceus, Lactobacillus plantarum, and Bacillus subtilis) in a feeding trial with broiler chickens. Birds given the probiotic were predicted to show an improved growth performance with …

Evaluation Of Endothelial Cell Responses To Elevated Glucose, Gabriella Sugerman

Master's Theses

Developing a tissue-engineered Blood Vessel Mimic (BVM) to represent diabetic macrovascular disease could expedite design of new vascular devices specifically tailored to diabetic patients. In contribution toward this model, this thesis assessed Human Umbilical Vein Endothelial Cell (HUVEC) responses to high glucose conditions. Interleukin 6 (IL-6) and Cluster of Differentiation 36 (CD36) were selected to signify oxidative stress activity, a hallmark of diabetic macrovascular disease. Next, activity of potential reference genes B2M, HPRT1, and ACTB was assessed. All genes were found to exceed acceptable variability, so the E-ΔC T method of data analysis was selected. Next, cellular responses to high …

Pink And Dude Chefs: Effectiveness Of An After-School Nutrition Knowledge And Culinary Skills Program For Middle School Students To Increase Fruit And Vegetable Consumption, Alyssa S. Vaziri

Master's Theses

The rate of overweight and obesity among adolescents aged 12-19 years has more than tripled since 1980, and disproportionately impacts low-income and marginalized populations. Reduction in adolescent obesity rates may result in decreased health risks, decrease healthcare costs, and increased quality of life. Effective intervention methods for adolescent participants have incorporated nutrition knowledge and culinary skill building into afterschool programs. This study examines whether building knowledge, skills, and confidence through a culinary intervention can improve adolescent participants’ choices of healthful foods through increased fruit and vegetable intake.

Pink and Dude Chefs (PDC) is an afterschool nutrition education and culinary skills …
