Each year, approximately 2.8 million adults die from complications related to obesity (World Health Organization, 2011). One in three adults aged 20 years or older is obese, and 6% are morbidly obese. This problem is increasing at an alarming rate in young adults, and 20.5% of college students are classified as being overweight based upon their body mass index (BMI) (Adderley-Kelly, 2007). The purpose of this study was to increase knowledge about evidence-based, effective interventions that will enable college-aged, pre-nursing students to attain physical and mental well-being. The participants (N=24) were freshman and sophomore pre-nursing majors who were randomized into …

House Finches, Carpodacus Mexicanus: Hormones, Stress, And Song Control Regions, Katherine Olivia Ganster

Master's Theses

Song production in songbirds is controlled by parts of the brain known as the song control regions (SCRs). During spring, gonads increase in size, males sing to attract mates, and SCRs become larger. This neuroplasticity is controlled by the change in day length and increased plasma testosterone (T) levels. Plasma T can be reduced by stress through the production of corticosterone (CORT), through the production of beta-endorphin, or through direct effects on the testes via the nervous system. We determined the T, estradiol, and CORT hormonal profiles of wild House Finches by capturing and sampling blood from the finches every …

The Relationship Between Heart Rate Variability, Shooting Experience, And Tactical Pistol Performance, Andrew Gerard Thompson

Human Movement Studies & Special Education Theses & Dissertations

PURPOSE: At rest and during a tactical pistol competition classifier, heart rate variability (HRV) time-domain, high frequency (HF), low frequency (LF), total power (TP), and inter-beat-interval (IBI) measurements were examined in 28, healthy subjects (37 ± 11 yr old, 180 ± 7 cm, 90.6 ± 16.9 kg) for correlations to performance. METHODS: Resting measurements were taken supine in a quiet, dimmed room, during metronomic breathing. The shooting task consisted of three stages, comprised of several strings each. The strings were initiated by a starting buzzer and involved several tactical maneuvers, including holster draws, engaging multiple targets, firing on the move, …

The Proteomic Response Of Sea Squirts (Genus Ciona Congeners) To Hyposalinity Stress, James S. Koman

Master's Theses

The ascidian species Ciona savignyi and C. intestinalis are invasive species but show interspecific differences in their population response to hypo-saline stress associated with heavy winter-run off events that are predicted to become more frequent due to climate change. Despite an almost world-wide distribution, C. intestinalis seems to be more susceptible to hypo-saline stress than the geographically more limited C. savignyi. Given that the genomes of both species are fully sequenced, we were able to compare their proteomic response to both acute and chronic salinity to characterize the mechanisms that are responsible for setting tolerance limits to hyposaline conditions …

Gender Related Differences In Stress And Health Outcomes In College Age Students, Michael Cedeno, Jennifer Blevins-Mcnaughton

International Journal of Exercise Science: Conference Proceedings

Background and Purpose: Rates of obesity and metabolic disorders in young adults are becoming more prevalent in today’s society. To date, only a few investigators have compared the effect that stress may have on health and metabolic outcomes in college age adults. The purpose of this study is to determine the relationship between stress and cholesterol levels in male versus female college age students.

Methods: Thirty-six adults ages 20 to 27 participated in this study. Total blood cholesterol, HDL, LDL, triglycerides, TC/HDL ratio, and glucose were measured one time using the Cholestech LDX® after either an overnight, or 4-hour fast. …

Improving Psychological And Physical Health In Women Of Color Via Salsa Dancing, Scherezade K. Mama, Ashley V. Medina, Raul O. Edwards, Lorna Mcneill, Rebecca E. Lee

International Journal of Exercise Science: Conference Proceedings

Purpose: Physical activity improves psychological and physical health. Latin dancing is popular and can be used to meet moderate to vigorous physical activity intensity recommendations. The purpose of this study was to determine whether participation in a Latin dance intervention reduced perceived stress and improved health. Method: SAving Lives, Staying Active (SALSA) was an 8-week randomized controlled cross-over design, pilot study to promote regular physical activity from Latin dance and fruit and vegetable consumption as a means to preventing obesity among women of color in Houston, Texas. Participants were randomized to a four week bi-weekly salsa dance or web-based dietary …

Interactions Between Connected Half-Sarcomeres Produce Emergent Mechanical Behavior In A Mathematical Model Of Muscle, Kenneth S. Campbell

Physiology Faculty Publications

Most reductionist theories of muscle attribute a fiber's mechanical properties to the scaled behavior of a single half-sarcomere. Mathematical models of this type can explain many of the known mechanical properties of muscle but have to incorporate a passive mechanical component that becomes approximately 300% stiffer in activating conditions to reproduce the force response elicited by stretching a fast mammalian muscle fiber. The available experimental data suggests that titin filaments, which are the mostly likely source of the passive component, become at most approximately 30% stiffer in saturating Ca2+ solutions. The work described in this manuscript used computer modeling to …

Salivary Cortisol, Psychological Stress And Depressive Symptoms Among Patients Undergoing Colon Cancer Screenings, Allyson Reid

Honors Scholar Theses

As the second leading cause of cancer-related deaths in the United States, colon cancer has a high cure rate if detected early by a colonoscopy (U.S.

Cancer Statistics Working Group, 2007). However, more than 41 million at-risk Americans are not properly receiving colonoscopy screenings according to the recommendations of the Center for Disease Control. This study provides insight into the physiological and psychological benefits of the colonoscopy procedure over and above cancer detection and prevention. Thirty-six patients receiving colonoscopic screening at the University of Connecticut Health Center participated in this study. A questionnaire battery that assessed perceived stress, depressive symptoms, …

Il-1Α And Tnf-Α Down-Regulate Crh Receptor-2 Mrna Expression In The Mouse Heart, Sarah C. Coste, Kurt A. Heldwein, Susan L. Stevens, Eric Tobar-Dupres, Mary P. Stenzel-Poore

Faculty Publications

Two receptors (CRH receptor type 1 and CRH receptor type 2) have been identified for the stress-induced neuropeptide, CRH and related peptides, urocortin, and urocortin II. We previously found marked down-regulation of cardiac CRH receptor type 2 expression following administration of bacterial endotoxin, lipopolysaccharide, a model of systemic immune activation, and inflammation. We postulated that inflammatory cytokines may regulate CRH receptor type 2. We show that systemic IL-1α administration significantly down-regulates CRH receptor type 2 mRNA in mouse heart. In addition, TNFα treatment also reduces CRH receptor type 2 mRNA expression, although the effect was not as marked as with …

Changes In Caloric Content As A Result Of Sub-Lethal Stress In Neanthes Virens (Sars), Phyllis J. Friello

Biological Sciences Theses & Dissertations

Neanthes virens were subjected to a toxicity test with 1.8, 3.4, 6.7 and 11.0 mg/1 Cd²⁺. Worms were withdrawn on Days 1, 4, 7, 10 and 14 from each of five replicate tanks and their caloric content determined by bomb calorimetry. Analyses of variance and covariance showed no significant differences in worm caloric content with withdrawal day or cadmium concentration.

In a second experimental series, a sediment toxicity test with Neanthes virens was conducted in contaminated sediments from two sites, as well as reference sediments from a control site. Caloric content of the worms was measured by bomb …
