We examined the association between genotype and resistance training-induced changes (12 wk) in dual x-ray energy absorptiometry (DXA)-derived lean soft tissue mass (LSTM) as well as muscle fiber cross-sectional area (fCSA; vastus lateralis; n = 109; age = 22 ± 2 y, BMI = 24.7 ± 3.1 kg/m2). Over 315 000 genetic polymorphisms were interrogated from muscle using DNA microarrays. First, a targeted investigation was performed where single nucleotide polymorphisms (SNP) identified from a systematic literature review were related to changes in LSTM and fCSA. Next, genome-wide association (GWA) studies were performed to reveal associations between novel SNP targets with …

An Assessment On Microplastic Pollution In The Resacas Of The Lower Rio Grande Valley, Texas, Wesley D. Franklin

Theses and Dissertations

Microplastic pollution is a serious issue that impacts most aquatic environments. Microplastics have the potential to cause numerous detriments to the fitness and reproductive capability of many organisms. The resacas of the Lower Rio Grande are an understudied area that could be sinks for large congregations of microplastics. We analyze microplastic pollution in two species of fish as well as the sediment and water of eleven different pools from four resaca systems. We find that microplastics are present in every pool sampled.

Altogether 218 microplastic pieces are found from the water, sediment and fish samples. We find that microplastics are …

Trophic Ecology Of Mesopelagic Fish Larvae And Juveniles In The Northern Gulf Of Mexico, Emily Gipson

Master's Theses

The deep-pelagic environment encompasses ocean waters below 200 m depth, and comprises 90% of the volume of the Gulf of Mexico. Deep-pelagic fishes are important prey for many oceanic consumers, but relatively little is known about their early life history, including larval fish trophic ecology. An understanding of the role deep-pelagic fish larvae have in oceanic food webs is important in the development of ecosystem models that examine the connectivity (via vertical migrations) between the deep-pelagic and epipelagic environments with respect to trophic interactions, nutrient cycling, and carbon sequestration. In this study, archived plankton samples collected during 2010 and 2011 …

Food Selection And Consumption During The Covid-19 Pandemic/Quarantine, Shawnyse Debaun, Pui Tan Lau

Loma Linda University Research Reports

Background: The Coronavirus disease 2019 (COVID-19) created an unexpected outbreak that led to a pandemic and the fear of scarcity regarding food. Due to those who shopped in panic, grocery stores began to limit the number of specific items purchased per family. The COVID-19 is a novel disease that has changed society by wearing face-coverings when out in public, temporarily closing indoor dining at restaurants, and converting schools online. The over-purchase of toilet paper and water caused many grocery and department stores to exhaust their inventory. This situation may have instilled fear of scarcity and leave to the over-purchase …

The Effects Of Religiosity On Gender-Differentiated Household Decision-Making In Indonesia, Juliann Phillips

Economics Undergraduate Honors Theses

Religion is a dominant influence in household decision-making and is an important factor in understanding intra-household bargaining power, especially within developing countries. It is important to understand the extent to which religious beliefs affect decisions made within the household when designing interventions to improve women’s agency. This paper examines the fourth wave of the Indonesia Family Life Survey using the difference-in-differences method to analyze the impact of Islamic religiosity on the likelihood of allowing women within the household to make certain decisions in eight critical categories. While stereotypical beliefs may negatively correlate women’s bargaining power and high levels of religiosity …

Vitamin B12 Deficiency Does Not Stimulate Amyloid-Beta Toxicity In A Ceanorhabditis Elegans Model Of Alzheimer’S Disease, Opeyemi F. Showemimo

Electronic Theses and Dissertations

Alzheimer’s disease (AD) is symptomized by amyloid-beta plaques in the brain and accounts for more than 65 percent of dementia cases. Vitamin B12 (cobalamin) deficiency can result in similar cognitive impairment and roughly 15% of the elderly are vitamin B12 deficient. Vitamin B12 deficiency results in the accumulation of toxic methylmalonic acid and homocysteine. Hyperhomocysteinemia is a strong risk factor for AD. To test if vitamin B12 deficiency stimulates amyloid-beta toxicity, Caenorhabditis elegans expressing amyloid-beta in muscle were fed either vitamin B12-deficient OP50-1 or vitamin B12-rich HT115(DE3) E. coli bacteria. Increased amyloid-beta toxicity was found in worms fed the …

“I Done Been Through Hell”: An Existential Phenomenological Study Of The Lived Experience Of Fathers Who Have Lost A Child, Dynisha Wigginson

Electronic Theses and Dissertations

The rise in American pediatric death led to a shift in pediatric end-of-life care from focusing care only on the dying pediatric patient to include focus on the family. Most literature has focused only on mothers’ experiences or the combined experiences of mothers and fathers. Fathers’ experiences at their child’s end of life, as an individual phenomenon, is overlooked and ignored. Hence, significant knowledge gaps exist related to the repeated exclusion of fathers’ individual experiences. This study aimed to begin to fill this gap. Using the lens of Merleau-Ponty, this existential phenomenological study aimed to describe the lived experiences of …

A Case Study Of Four Districts' Procedures For Identifying And Serving Culturally, Linguistically, And Economically Diverse Gifted And Talented Students In One State, Mackenzie Anderson

Curriculum and Instruction Undergraduate Honors Theses

The underrepresentation of culturally, linguistically, and economically diverse students is a problem historically researched in gifted and talented programs. This problem largely comes from the way districts identify for giftedness as well as the programming for gifted students. Traditional methods of identification often largely exclude students due to racial or ethnic bias and harsh cut-off scores on tests. This study investigated the current identification procedures of four districts in one state. Additionally, the study addressed programming and how these districts specifically targeted underserved populations within their district. Data were collected through interviews with four District Coordinators from school districts with …

Optimization Of Broken Rice Consumption Through Understanding The Confluence Of Sensory And Economic Preferences, Matthew Greer Richardson

Graduate Theses and Dissertations

The authors were perplexed by the seeming dichotomy between the majority 70% of Haitian consumers being chronically food insecure, but still preferring to pay premium international market prices for long-grain rice that constitutes 30% of the calories in this poorest nation in the Western Hemisphere. The aim of this study was to determine the optimal percent broken rice in regards to price specifically to Haiti. Optimization between quality and price point is seen as the best rice for the price, and can be found through combining individual preferences with willingness to pay. Broken rice (brokens) garner a significantly discounted price …

Quantifying The Leaching Of Nutrients And Metals In A Pasture Soil As Affected By Excreta Of Ruminants Fed Alternative Diets, Ian Kennedy

Graduate Theses and Dissertations

The leaching of nitrate through the soil profile and into adjacent water systems has been a leading cause of water pollution and results in the loss of a valuable nutrient from animal production systems. Forage-based animal production systems may be improved through manipulation of animal diets that incorporate tannins and total polyphenolic compounds with feed, increasing the amount of nitrogen (N) retained by an animal/decreasing rates of digestion and altering the N-containing compounds that are excreted and deposited onto soil. Incorporating the forage legumes sericea lespedeza (Lespedeza cuneate [Dumont de Courset] G. Don) and lablab (Lablab purpurues L.) into the …

Starter Nitrogen Source And Preflood Nitrogen Rate Effects On Rice Grown On Clay Soils, Linda Rachelle Martin

Graduate Theses and Dissertations

Seedling rice (Oryza sativa L.) grown on clayey-textured soils generally develops slowly as compared to loamy-textured soils. Our research examined the effects of starter-N source and preflood-N rates on canopy closure, total aboveground N uptake, and grain yield of rice grown on clayey-textured soils. Eleven field trials were established in Arkansas and Mississippi including five trials with a hybrid cultivar and six trials using a pure-line cultivar. Starter-N sources included no starter-N (NONE), ammonium sulfate (AMS), diammonium phosphate (DAP), and urea (UREA) applied at 24 kg N ha-1 at the rice 2-leaf stage and five preflood-N rates ranging from 0-224 …

Peptoid-Based Microsphere Coatings For Biomaterial Applications, Jesse Leland Roberts

Graduate Theses and Dissertations

Peptoids are peptidomimetic oligomers that predominantly harness similarities to peptides for biomimetic functionality. The incorporation of chiral, aromatic side chains in the peptoid sequence allows for the formation of distinct secondary structures and self-assembly into supramolecular assemblies, including microspheres. Peptoid microspheres can be coated onto substrates for potential use in biosensor technologies, tissue engineering platforms, and drug-delivery systems. They have the potential for use in biomedical applications due to their resistance to proteolytic degradation and low immunogenicity. This dissertation focuses on the physical characteristics and robustness of the peptoid microsphere coatings in various physiological conditions, along with their ability to …

Sex-Based Differences In Acvr2b And Grb10 Expression In Skeletal Muscle During Induced Cancer Cachexia And Disuse, Lauren Martinez

Graduate Theses and Dissertations

Background: Muscle atrophy is the shrinkage of muscle fibers that are largely maintained by a balance of protein synthesis and degradation. Imbalances in protein synthesis and degradation are observed in different muscle atrophy disorders such as cancer cachexia and disuse. These forms of muscle atrophy produce distinct wasting pathologies that are influenced by biological sex. Activin receptor type-2B (ACVR2B) and Growth factor receptor-bound protein 10 (GRB10) have been identified as genes that potentially regulate muscle mass while also displaying sexually dimorphic differences. Purpose: To examine the influence of ACVR2B and GRB10 throughout the development of cancer cachexia and disuse-induced atrophy …
