Effect Of Grazing Pressure On Cattle Grazing Cool Season Annual Forages, Brooke Brunsvig

Electronic Theses and Dissertations

Ruminants can use plant fiber to produce food products that provide nourishment to humans. However, a precise understanding of specific plants selected by grazing ruminants remains elusive. Many long- and short-term factors impact cattle grazing behavior. Ultimately, grazing behavior can affect forage available for grazing, nutrient density of forage, dry matter intake, and animal performance. A myriad of grazing management strategies have been developed utilizing animal behavior to allow more efficient use of forage resources. Many management strategies based on manipulation of grazing behavior are simple and cost effective. Optimal performance of individual animals and amount of animal products produced …

Using Gluten Index To Improve Spring Wheat Loaf Volume Prediction, Yaming Lu

Electronic Theses and Dissertations

Wheat (Triticum aestivum L.) is the most widely cultivated crop in the world and contributes about 20% of the total dietary calories and proteins globally. Unique properties of doughs formed from wheat flour make it feasible to produce a range of food, including bread. Loaf volume is the most perceptible indicator for breadmaking quality. Selection in the early generations for loaf volume is difficult due to the requirement of the large volume of grains and due to the costly, time-consuming, and labor-intensive evaluation process. Identification of simple and reliable predictive tests for loaf volume is highly desirable. This study …

Goals Of Exclusive Breastfeeding And The Effectiveness Of Programs And Initiatives In Attaining Them, Natalie Scott

Senior Honors Theses

Over recent years, breastfeeding has gained renewed significance in research and practice. Both in the United States and around the world, especially in poor countries that do not have easy access to quality healthcare, breastfeeding has been shown to dramatically and positively affect the health and lifespan of infants. However, there is still a low prevalence of effective breastfeeding practices universally. Even with the presence of global programs and goals that are geared toward exclusive breastfeeding habits, global rates are lower than what is desired. There are various determinants of breastfeeding that factor into a woman’s decision and practice of …

Antibiotic Overuse: The History, Consequences, And Possible Solutions, Brooke A. Bost

Swomley, Judy C. Triplett, Jeriel T. Keeney, Govind Warrier, Kevin J. Pearson, Julie A. Mattison, Rafael De Cabo, Jian Cai, Jon B. Klein, D. Allan Butterfield

Chemistry Faculty Publications

A diet consisting of a high intake of saturated fat and refined sugars is characteristic of a Western-diet and has been shown to have a substantial negative effect on human health. Expression proteomics were used to investigate changes to the parietal lobe proteome of rhesus monkeys consuming either a high fat and sugar (HFS) diet, a HFS diet supplemented with resveratrol (HFS+RSV), or a healthy control diet for 2 years. Here we discuss the modifications in the levels of 12 specific proteins involved in various cellular systems including metabolism, neurotransmission, structural integrity, and general cellular signaling following a nutritional intervention. …

The Impact Of Conditional Cash Transfers On Nutrition: Evidence From Mexico, Natalie Kronebusch

Economics Honors Projects

In this paper, I study the effect of Oportunidades, a conditional cash transfer program in Mexico, on the micronutrient and macronutrient levels of program recipients. Overall, I find that Oportunidades has a positive, significant impact on micronutrient acquisition for Oportunidades beneficiaries. Program participants consume 20.5% more vitamins and 10.1% more minerals than individuals living in non-treatment households. This change could be critical for reducing rates of micronutrient deficiencies in low- and middle-income countries. Furthermore, I conclude that although Oportunidades induces higher micronutrient consumption, program recipients also consume higher levels of calories, fat, and sodium, all of which could be …

Irisin Levels Are Not Associated To Resistance Training-Induced Alterations In Body Mass Composition In Older Untrained Women With And Without Obesity, R A. Tibana, D Da Cunha Nascimento, N M. Frade De Souza, V C. De Souza, I V. De Sousa Neto, F A. Voltarelli, G B. Pereira, J W. Navalta, J Prestes

Kinesiology and Nutrition Sciences Faculty Research

Objective: The present study aimed to determine whether Irisin levels are correlated with body composition changes following 16 weeks of resistance training (RT) in older women with and without obesity. Design, Setting, Participants, Intervention: We recruited 49 inactive women (n = 23, non-obese: < 41.0% and n = 26, obese: ≥ 41.0% of body fat) aged 61–68 years to perform 16-week of RT consisting of 10 exercises (three sets of 10 exercises, 6-12 repetitions maximum and 1-min and 30-s rest intervals between sets and exercises, respectively) with two sessions per week. Measurements: Before and after the intervention period, blood samples were collected to determine Irisin levels and body composition (percentage body fat and fat-free mass) was measured by dual energy x-ray absorptiometry. Results: Circulating Irisin displayed a decrease for the non-obese group as compared with pre-intervention and obese group (p = 0.01 and p = 0.04, respectively), with no change for the obese group (p = 0.79). In addition, fat mass displayed a significant reduction (p < 0.05) following the training period only for the obese group. Furthermore, there was no association between changes in circulating Irisin with body mass index, body fat, fat-free mass and muscle strength. There was an increase in muscle strength (p < 0.05), regardless of obesity status. Conclusion: The modulation of body composition and muscle strength induced by 16-week of resistance training in older women with and without obesity is not associated with changes in circulating Irisin levels. © 2016, Serdi and Springer-Verlag France.

Kinesiology and Nutrition Sciences Faculty Research

The purpose of this study was to investigate the effects of wearing a wetsuit on resting cardiovascular measures (blood pressure (BP), heart rate variability (HRV)). The influence of position (upright, prone) and wetsuit size were also explored. Participants (n=12 males, 33.3±12.1 years) had BP and HRV measured during six resting conditions: standing or prone while not wearing a wetsuit (NWS), wearing the smallest (SWS), or largest (LWS) wetsuit (based upon manufacturer guidelines). Heart rate was recorded continuously over 5-mins; BP was measured three times per condition. HRV was represented by the ratio of low (LF) and high (HF) frequency (LF/HF …

Vitamin D Status And Bone Mineral Density In Female Collegiate Dancers And Cheerleaders, Tara Sue Kenny, Damon Mccune, Laura J. Kruskall, James Navalta, John C. Young

Kinesiology and Nutrition Sciences Faculty Research

Bone mineral density reflects an athlete’s cumulative history of energy availability, physical activity, and menstrual status, as well as nutritional and environmental factors. Although sports with high-impact loading are associated with higher bone mineral density than low-impact or non-impact sports, confounding variables are differences in the athletes’ body size and sport-specific training. The purpose of this study was to determine if bone mineral density (BMD) and vitamin D status are different between two groups of female collegiate athletes who have comparable body size/weight requirements, but who engage in qualitatively different training regimens. Full body, spine and dual femur BMD was …

Anthropometric Measures Of Hadza Forager Children And Juveniles: Implications For Anthropology And Human Biology, Elle Ford, Alyssa N. Crittenden

McNair Poster Presentations

Understanding growth trajectories during child development is important for the fields of human biology, public health, medicine, and evolutionary medicine. To date, the majority of current references for childhood development and health are primarily derived from the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). To ensure a child is developing properly, is equipped with proper nutrition, and will sustain a healthy life through adolescence and adulthood, these measurements and standards are necessary. The current study aims to test whether or not these standards are applicable in non-industrial small-scale societies where differences from western populations …

Implementation Of A Loss-Of-Function System To Determine Growth And Stress-Associated Mutagenesis In Bacillus Subtilis, N Villegas Negrete, E A. Robleto, A Obregon Herrera, R E. Yasbin, M Pedraza Reyes

Life Sciences Faculty Research

A forward mutagenesis system based on the acquisition of mutations that inactivate the thymidylate synthase gene (TMS) and confer a trimethoprim resistant (Tmpr) phenotype was developed and utilized to study transcription-mediated mutagenesis (TMM). In addition to thyA, Bacillus subtilis possesses thyB, whose expression occurs under conditions of cell stress; therefore, we generated a thyB- thyA+ mutant strain. Tmpr colonies of this strain were produced with a spontaneous mutation frequency of ∼1.4 × 10-9. Genetic disruption of the canonical mismatch (MMR) and guanine oxidized (GO) repair pathways increased the Tmpr frequency of mutation by ∼2-3 orders of magnitude. A wide spectrum …

Smarter Food Policies Are Needed To Make Significant Progress Towards Eradicating Food Insecurity In America, Dawn Matusz

Brookings Mountain West Publications

Speaking of malnutrition conjures images of starving African children as presented by the media and humanitarian organizations. We think about famine ridden lands, places where emaciated victims who have very little access to food. Malnutrition does not conjure images of obese youth and financially struggling families living amidst excessive consumption in America. Although an alarming paradox, malnutrition can and does exist in what some would call the wealthiest and most powerful nation on Earth, but yet it does exist.

Synthesis Of Ag10 Analogs And Optimization Of Ttr Ligands For Half-Life Enhancement (Tlhe) Of Peptides, Raghavendra Jampala

University of the Pacific Theses and Dissertations

The misassembly of soluble proteins into toxic aggregates, including amyloid fibrils, underlies a large number of human degenerative diseases. Cardiac amyloidosis, which is most commonly, caused by aggregation of Immunoglobulin (Ig) light chains or transthyretin (TTR) in the cardiac muscle, represent an important and often underdiagnosed cause of heart failure. TTR-mediated amyloid cardiomyopathies are chronic and progressive conditions that lead to arrhythmias, biventricular heart failure, and death. As no Food and Drug Administration-approved drugs are currently available for treatment of these diseases, the development of therapeutic agents that prevent TTR-mediated cardiotoxicity is desired. AG10 is a potent and selective kinetic …

Using The Medication Cabinet To Predict Fall Risk In Elderly Adults, Jessica Lopez

University of the Pacific Theses and Dissertations

Background: In the United States, 30-60% of older adults fall each year; 10-20% of these falls result in injury, hospitalization, or even death. Better prevention of falls in this population may be facilitated by broader identification of risk factors. The use of statins has emerged as a potential risk factor, but the data provide conflicted results.

Purpose: To examine the relationship between statin use and falls among community-dwelling older adults.

Methods: We evaluated the patient registry of a Level 1 trauma center. All patients aged > 50 years who were admitted for falls in 2015 were included (n=615). Many of these …

Bioimpedance Spectroscopy - Can It Be Used As A Tool For Monitoring Fluid Shifts In Burns?, Pippa Kenworthy

Theses

Large fluid shifts and oedema are features of burn injuries. Oedema hampers burn wound healing and is directly related to the size and depth of the burn. The degree of oedema in burns covers a broad spectrum: Minor burns cause localised or peripheral oedema, whilst major burns may result in a systemic inflammatory response which can be life threatening and necessitates formal fluid resuscitation. Acute burn fluid resuscitation is paramount in decreasing patient morbidity and mortality but can contribute to already large amounts of oedema. There is currently no single clinically applicable, non-invasive and accurate outcome measure to titrate fluid …

An Exploratory Study Of Burial Identification Using Historic Human Remains Detection Dog Alerts And Inorganic Soil Analyses, Britt Schlosshardt

Graduate Student Theses, Dissertations, & Professional Papers

One point at which forensic science and historical archaeology intersect, and the focus of this thesis, is using the decidedly forensic avenues of trained dogs, probing, and chemical analyses of soils, informed by archaeological survey, to locate burials. Human remains detection dogs have proven to be a nonintrusive and effective method for identifying or confirming historic unmarked burial locations. Inorganic soil analyses have been demonstrated in prior research to show variations in grave soil. For this research, the hypothesis that is explored is that a corpse will chemically alter the soil in or on which it is placed to a …

Energy Budget For The African Cichlid, Tropheus Duboisi, Cortney Kay Morris

Browse all Theses and Dissertations

Herbivorous fish living in Lake Tanganyika rely on algae as their main source of food and are constantly feeding on low quality (low energy) food. The lake is warming leading to fewer nutrient upwelling’s that are likely limiting the amount of energy available to fish. I calculated an energy budget to compare energy intake against energy expenditure of the African cichlid, Tropheus duboisi, by measuring metabolic rates at rest, while feeding, digesting and being aggressive as well as the caloric content of food, feces, and urine. Fish fed a low quality diet of algae contaminated with sediments had lower growth …

Glycolytic Metabolism And Pregnancy Parameters In The Murine Placenta, Renee Elizabeth Albers

Browse all Theses and Dissertations

The placenta is a complex and essential organ composed largely of fetal-derived cells, including several different trophoblast subtypes that work in unison to support nutrient transport to the fetus during pregnancy. Abnormal placental development can lead to pregnancy-associated disorders that often involve metabolic dysfunction. The scope of dysregulated metabolism during placental development may not be fully representative of the in vivo state in defined culture systems, such as cell lines or isolated primary cells. Thus, assessing metabolic function in intact placental tissue would provide a better assessment of placental metabolism. In this study, we describe a methodology for assaying glycolytic …

Association Of Gut Luminal Metabolites And Allergic Responses, Ghaith Mohammed Fallata

Browse all Theses and Dissertations

Allergy is a global health problem, affecting more than 40% of the world population. Allergy is often associated with a dysregulation of the immune system that becomes overactive against allergens. Several genes are known to be important for the proper homeostasis of the immune system in the epithelial tissues, and the loss of function of genes such as IKKß or SOX9 impacts the interaction between external stimuli and the host. Many of the allergic responses are triggered through the regulatory cascade governed by transcriptional factor NF-κB. Regulation of NF-κB activity is complex, involves several alternative routes, and is also influenced …
