Nutrition Able: A Lecture-Based Intervention To Promote Nutritional Literacy About Protein Intake In Women, Jeffery Bolte, Alejandra Garcia, Jacob Abalos, Jakson Johnson, Alex Joyce, Christopher Hinds, Jared Tuttle, Jeff Svec

International Journal of Exercise Science: Conference Proceedings

Sport performance is influenced by sport-specific requirements for body composition. One major predictor of body composition is protein intake. Higher protein intake tends to cause leaner body composition relative to lower protein intake, especially during caloric deficit. In Bexar County, ~72% of the adult population is overweight/obese and 15.5% are diabetic. This suggests that high protein diet could be a high leverage option in the San Antonio population for optimizing body composition for sport performance. Furthermore, late life sporting activity and protein intake is a primary method for mitigating sarcopenia, osteoporosis, fractures, and accidental death in post-menopausal women. PURPOSE: …

Influences Of Post-Fledging Protein Supplementation On Growth And Reactive Stress Response In Zebra Finches (Taeniopygia Castanotis), Gabrielle Morris, Mary Lindley Tharp

Honors Theses

Protein needs of non-poultry birds, like Zebra Finches (ZF) are understudied. ZFs consume proteinaceous half-ripe seeds during breeding and chicken eggs are recommended supplements for captive ZFs; but developmental needs are unclear. Eggs contain essential amino acids that impact the “stress” hormone, corticosterone (CORT). Diet and corticosterone influence avian growth and stress management. Juvenile egg-fed ZFs outgrow seed-fed birds. Juvenile egg-supplementation boosts adult male attractiveness due to cheek patch augmentation compared to seed-only birds. Across studies, timing of diet (nestling Vs. fledgling) varies, both sexes have not been included, and simultaneous measures of growth and corticosterone are lacking. We are …

Food Sensitives In Athletes: Whey More Common Than You May Expect?, Eve M. Clarkson Miss, Brittanie L. Lockard, Ben Garza, Julianne Damico, Terah Ege

International Journal of Exercise Science: Conference Proceedings

Food sensitives, which differ from food allergies, are caused by digestive problems to foods that may lead to symptoms such as bloating, diarrhea, constipation, fatigue, headache, joint pain, and sleep disturbances, among other issues. It is estimated that food sensitivities affect 15-20% of the US population. These are IgG antibody-mediated responses that may develop from a variety of causes such as enzymatic defects in the digestive system. Research suggests that IgG-based tests produce clinically meaningful results that aid in the development of a targeted elimination diet. In a non-athletic sample with food sensitivities, our lab previously reported that 70% of …

An Approach To Developing Benchmark Datasets For Protein Secondary Structure Segmentation From Cryo-Em Density Maps, Thu Nguyen, Yongcheng Mu, Jiangwen Sun, Jing He

Computer Science Faculty Publications

More and more deep learning approaches have been proposed to segment secondary structures from cryo-electron density maps at medium resolution range (5--10Å). Although the deep learning approaches show great potential, only a few small experimental data sets have been used to test the approaches. There is limited understanding about potential factors, in data, that affect the performance of segmentation. We propose an approach to generate data sets with desired specifications in three potential factors - the protein sequence identity, structural contents, and data quality. The approach was implemented and has generated a test set and various training sets to study …

Mistranslating Trnas Alter The Heat Shock Activation By Hsf1, Rebecca Dib

Undergraduate Student Research Internships Conference

Translation, or the production of protein from an mRNA blueprint, is among the most fundamental processes to life as we know it. tRNAs are essential to accurate translation, as they decode the codons of mRNA and recruit corresponding amino acids. Variant tRNAs with anticodon mutations can decrease translational fidelity by recruiting the incorrect amino acid, an aberrant process known as mistranslation. When proteins are produced with incorrect amino acid sequences, they may misfold. The heat shock response functions to alleviate cellular stress caused by misfolded proteins, either by refolding or targeting misfolded proteins for degradation. Hsf1 acts as a transcriptional …

School of Podiatric Medicine Publications and Presentations

Due to its excellent chemical and mechanical properties, titanium has become the material of choice for orthopedic and dental implants to promote rehabilitation via bone anchorage and osseointegration. Titanium osseointegration is partially related to its capability to form a TiO2 surface layer and its ability to interact with key endogenous proteins immediately upon implantation, establishing the first bone–biomaterial interface. Surgical trauma caused by implantation results in the release of high-mobility group box 1 (HMGB1) protein, which is a prototypic DAMP (damage-associated molecular pattern) with multiple roles in inflammation and tissue healing. To develop different surface strategies that improve the clinical …

The Role Of Nutrition And Hormone Signaling In Extended Larval Development And Obesity In Starvation-Selected Drosophila Melanogaster, Jennifer M. Clark

UNLV Theses, Dissertations, Professional Papers, and Capstones

Brief periods of starvation are a common stressor that most animals encounter in the wild and must be able to survive in order to maximize their fitness. Starvation resistance of the adult fruit fly, Drosophila melanogaster, is thought to be primarily conferred by adult fat stores, body size, metabolic rate, behavior, and activity levels. Additionally, flies selected for starvation resistance also often show delayed pupariation, which is usually indicative of altered hormone signaling. How starvation selection extends development and if it contributes to adult starvation resistance remains incompletely studied. Identifying the targets of starvation selection that cause extended development and …

Biophysical Characterization Of The Par-4 Tumor Suppressor: Evidence Of Structure Outside The Coiled Coil Domain And Interactions With Platinum Chemotherapeutics, Andrea Megan Clark

Chemistry & Biochemistry Theses & Dissertations

Prostate apoptosis response-4 (Par-4) is an apoptosis-inducing tumor suppressor protein. Full-length Par-4 has previously been shown to be a predominantly intrinsically disordered protein (IDP) under neutral conditions, with significant regular secondary structure evident only within the C-terminal coiled coil domain. However, IDPs can gain ordered structure through the process of induced folding, which often occurs under non-neutral conditions. Previous work has shown that the Par-4 leucine zipper, which is a subset of the C-terminal coiled coil domain, is disordered under neutral conditions, but forms a dimeric coiled coil at acidic pH. Increase in ionic strength was also shown to increase …
