Fecal-Sac Ingestion By Spotted Towhees, Jenny E. Mckay, Michael T. Murphy, Sarah Bartos Smith, Jennifer K. Richardson Aug 2009

Fecal-Sac Ingestion By Spotted Towhees, Jenny E. Mckay, Michael T. Murphy, Sarah Bartos Smith, Jennifer K. Richardson

Biology Faculty Publications and Presentations

Altricial nestlings encase excrement in fecal sacs that parents remove by either ingesting them or transporting them away from the nest. Ingestion may allow energetically or nutritionally deprived parents to recapture energy or nutrients that might be lost because of nestlings' inefficient digestion (the "parental-nutrition hypothesis"), but ingestion may also permit parents to avoid flights from the nest that interfere with parental care (e.g., brooding young; the "economic-disposal hypothesis"). We used a hypothetico-deductive approach to test the two hypotheses' ability to account for fecal-sac ingestion by the Spotted Towhee (Pipilo maculatus). We confirmed the parental-nutrition hypothesis' predictions that …

The Relationship Between Darkness Of Skin Tone And Mediators Of Elevated Blood Pressure, Brandy Trevino Aug 2009

The Relationship Between Darkness Of Skin Tone And Mediators Of Elevated Blood Pressure, Brandy Trevino

Theses and Dissertations - UTB/UTPA

Numerous studies have found that blood pressure is higher in persons with darker skin tone but the reasons for this remain unclear. This study attempted to investigate this relationship in Hispanics. If such a relationship was found, then it will be addressed whether or not one or more mediators, e.g., hostility, locus of control and perceived racial discrimination mediated the relationship. No such relationship between darkness of skin tone and blood pressure was found. However, statistically significant positive relationships between perceived racial discrimination, locus of control, and hostility were revealed. Discussion of these results focused on the plausible explanation of …

The Development And Nutritional Characteristics Of An Omega-3-Enhanced Egg Product, Nissan Michelle Kassis Aug 2009

The Development And Nutritional Characteristics Of An Omega-3-Enhanced Egg Product, Nissan Michelle Kassis

Graduate Theses, Dissertations, and Problem Reports (ETD)

Novel, nutritionally-enhanced egg product was developed by substituting saturated fat and cholesterol-containing yolk with omega-3 fatty acids-rich (o-3 FA) flaxseed, menhaden, algae, and krill oils. The o-3 FA-fortified eggs are typically developed through alteration of hen feed. However, the present study aimed at creating such a product via processing. Experimental batters were developed to match composition, color, and texture of hen eggs (whole egg). The batters, whole egg, and liquid egg product (egg beaters) were cooked, analyzed, and compared. Moisture, protein, and fat content of experimental eggs matched (P>0.05) whole egg. Nutritionally, amino acid profile (AAP) analysis showed no …

The Effects Of Omega-3 Polyunsaturated Fatty Acids On Ampk Activation And Lipid Metabolism In Skeletal Muscle, Myra Ellen Woodworth-Hobbs Aug 2009

The Effects Of Omega-3 Polyunsaturated Fatty Acids On Ampk Activation And Lipid Metabolism In Skeletal Muscle, Myra Ellen Woodworth-Hobbs

Graduate Theses, Dissertations, and Problem Reports (ETD)

Intramyocellular lipid accumulation and low lipid oxidative capacity contribute to the formation of insulin resistance, but omega-3 polyunsaturated fatty acids (n-3 PUFA) are shown to attenuate insulin resistance caused by high levels of saturated fats. The AMP-activated protein kinase (AMPK) promotes lipid oxidation and oxidative gene expression, highlighting its possible role in promoting insulin sensitivity by reducing lipid content and improving oxidative capacity. This study evaluated the effects of n-3 PUFA on the AMPK pathway and alterations to lipid content, oxidative markers, and insulin signaling proteins in a muscle cell culture model, with the hypothesis that n-3 PUFA would attenuate …

A Daily Process Analysis Of Short -Term Physical Activity Goal Pursuits In Midlife: Changes In Goal Processes, Physical Activity, And Subjective Well -Being, Eric A. Goedereis

Graduate Theses, Dissertations, and Problem Reports (ETD)

The prevalence of obesity in the United States increases with age, with the highest rates corresponding to midlife. Midlife health behaviors may play a contributing role in many of the health problems commonly associated with advanced age. Health psychologists who have embraced a life-span developmental perspective argue that it is important to consider the individual developmental trajectories of health and successful aging. Goal-setting has been shown to account for significant variance in physical activity, which has a variety of health-promoting benefits. In order to investigate individual variability in the daily processes of physical activity goal pursuit within a sample of …

Role Of Endothelin 1 In Follicular And Luteal Function In The Sheep, Fernando P. Perea-Ganchou Aug 2009

Role Of Endothelin 1 In Follicular And Luteal Function In The Sheep, Fernando P. Perea-Ganchou

Graduate Theses, Dissertations, and Problem Reports (ETD)

Three experiments were carried out in order to examine the role of endothelin in follicular steroid secretion in vitro and in spontaneous and PGF2alpha-induced luteolysis in sheep.;In experiment 1, it was hypothesized that endothelin 1 (END1) acting through its receptors ENDRA and/or ENDRB, on granulosal cells of ovine preovulatory follicles would inhibit steroid production, and therefore, prevent the premature luteinization of granulosal cells of those follicles. Data from estrogen-inactive 20 follicles collected from 13 ewes were analyzed. Accumulation of E 2 and P4 by cultured granulosal cells was not affected by either LH or END1 or the END receptor blockers. …

Effects Of Polyunsaturated Fatty Acids On Multidrug Resistance And Dna Methylation In Human Cancer Cell Lines, Cheng-Yi Kuan Aug 2009

Effects Of Polyunsaturated Fatty Acids On Multidrug Resistance And Dna Methylation In Human Cancer Cell Lines, Cheng-Yi Kuan

All Dissertations

Accumulating evidences indicate that dietary intake of long-chain polyunsaturated fatty acids (PUFAs) can affect various cellular processes and improve response of cancer cells to chemotherapy. The mechanisms by which PUFAs affect this response are not well understood. P-glycoprotein (P-gp), encoded by the multidrug resistance gene MDR1, is a drug efflux transporter that plays an important role in the bioavailability of anti-cancer drugs. Effects of long-chain polyunsaturated fatty acids on MDR1 gene expression and functional activity in the human colon cancer cell line Caco-2 were studied in this research. Caco-2 cells were treated with different concentrations of three PUFAs: eicosapentaenoic acid …

Depression And Health Among American Indian And Alaska Native Elders, Crystal R. Evans Aug 2009

Depression And Health Among American Indian And Alaska Native Elders, Crystal R. Evans

Theses and Dissertations

There is evidence of an association between depression, chronic disease, health status, and functionality among the elderly population. Research examining these relationships among American Indian elders is limited. This paper used data from the Identifying Our Needs: A Survey of Elders II to examine the relationships between target health variables and depression in a national sample of 10,743 American Indian elders. The data suggests that depression is significantly related to self-rated health, overnight hospital stays, spiritual activities, vigorous exercise, activity limitations, chronic disease, and community service usage. Additionally, self-rated health, limitations, binge drinking, and chronic disease were predictive of which …

Energy Drink Consumption In College Students: Report Of Physical And Psychological Symptoms In Association With Chronic Consumption Habits, Rebecca J. Cicha Aug 2009

Energy Drink Consumption In College Students: Report Of Physical And Psychological Symptoms In Association With Chronic Consumption Habits, Rebecca J. Cicha

Theses and Dissertations

Within the past decade, energy drink consumption has increased, particularly within young adult populations. Though current studies have investigated the acute effects of energy drink consumption, little data exists in regards to consumption patterns amongst college students, particularly differentiating acute vs. chronic consumers. As caffeine is recognized as the main acting ingredient in energy drinks, the effects of acute and chronic energy drink consumption may be related to that of general acute and chronic caffeine consumption. To date, much literature has highlighted a connection between caffeine intake and general pathology, specifically, that caffeine is highly correlated with the endorsement of …

Relationships Between Students’ Fitness Levels And Academic Achievement, Theresa Linam Roberts Aug 2009

Relationships Between Students’ Fitness Levels And Academic Achievement, Theresa Linam Roberts

Doctoral Dissertations and Projects

This study compared fifth grade students' physical fitness levels to academic achievement based on the premise that health and physical fitness has an effect on one's ability to learn and achieve academically. Due to No Child Left Behind and the mounting pressures to reach Adequate Yearly Progress, many school officials view non-assessed activities like physical education and recess as unnecessary, consequently creating a case for the elimination of any subject that is not directly measured through standardized testing. Finding a link between fitness and academic achievement may cause educational leaders to reevaluate time spent during the school day. Data was …

Schizophrenia Candidate Genes Study, Grace Lee Jul 2009

Schizophrenia Candidate Genes Study, Grace Lee

Theses and Dissertations

Schizophrenia is a debilitating disorder caused by the interaction of genetic and environmental factors. In this study, we identified candidate genes and single nucleotide polymorphisms from two genome-wide association studies, GAIN and CATIE. Nine SNPs representing four candidate genes were selected for replication studies with our Irish samples: Irish Case-Control Study of Schizophrenia (ICCSS), the Irish Study of High-Density Schizophrenia Families (ISHDSF), and the Irish Trio Study of Schizophrenia (ITRIO). In the ITRIO sample, rs4704591 (CMYA5 gene) showed nominal significance (p = 0.0447947). Combining ICCSS, ISHDSF, and ITRIO samples for rs4704591 increased sample size and power and yielded a p-value …
