Increased Body Weight In Adulthood Following A Peripubertal Stressor And Proposed Mechanism For Effects Of Increased Adiposity On Estrogen-Dependent Behaviors, Christina F. Gagliardi

Masters Theses

Exposure to certain stressors during a sensitive period around puberty can lead to enduring effects on an animal’s response to estradiol. In estradiol-influenced behaviors, such as sexual receptivity, hippocampal-dependent learning and memory, depression-like behavior, and anxiety-like behaviors, exposure to a peripubertal stressor such as shipping stress or an injection of lipopolysaccharide (LPS) can eliminate or even reverse the normal response to estradiol. In addition to regulating these behaviors, estradiol play a role in the regulation of body weight. While some of the previous studies touched on short-term effects on body weight, no systemic long-term study of the effects of a …

Can Anyone With Low Income Be Food Secure?: Mitigating Food Insecurity Among Low Income Households With Children In The Tampa Bay Area, Edgar Allan Amador

USF Tampa Graduate Theses and Dissertations

In the US over the last few years, approximately 14.5% of households experience food insecurity at some point throughout the year. While studies on food insecurity in the US have determined that household income and specifically income available to spend on food is of critical importance to food security, it is still unclear why some households with low income are able to maintain food security while others experience food insecurity in a pattern characterized as not constant but recurrent. This dissertation compares households with children at different levels of food security and insecurity using the USDA Core Food Security Module …

Laboratory Routines Cause Animal Stress, Jonathan P. Balcombe, Neal D. Barnard, Chad Sandusky

Jonathan Balcombe, PhD

Eighty published studies were appraised to document the potential stress associated with three routine laboratory procedures commonly performed on animals: handling, blood collection, and orogastric gavage. We defined handling as any non-invasive manipulation occurring as part of routine husbandry, including lifting an animal and cleaning or moving an animal's cage. Significant changes in physiologic parameters correlated with stress (e.g., serum or plasma concentrations of corticosterone, glucose, growth hormone or prolactin, heart rate, blood pressure, and behavior) were associated with all three procedures in multiple species in the studies we examined. The results of these studies demonstrated that animals responded with …

Linking Social Behavior And Stress Physiology In Feral Mares (Equus Caballus): Group Transfers Elevate Fecal Cortisol Levels, Cassandra M.V. Nuñez, James S. Adelman, Jessica Smith, Laurence Gesquiere, Daniel I. Rubenstein

Cassandra M.V. Nuñez

Feral horses (Equus caballus) have a complex social structure, the stability of which is important to their overall health. Behavioral and demographic research has shown that decreases in group (or band) stability reduce female fitness, but the potential effects on the physiological stress response have not been demonstrated. To fully understand how band stability affects group-member fitness, we need to understand not only behavioral and demographic, but also physiological consequences of decreases to that stability. We studied group changes in feral mares (an activity that induces instability, including both male and female aggression) on Shackleford Banks, NC. We found that …

The Importance Of Managing Psychosocial Health: A Case Study, Mary Insana Fisher, Harold L. Merriman

Physical Therapy Faculty Publications

Managing the physical aspects of lymphedema requires an individual to be committed to daily treatment of this chronic condition. Performing manual lymph drainage, using compression bandaging or compression garments, exercising, and caring for the skin all take time and a high level of dedication. This commitment to self-care can be emotionally and psychologically exhausting.

When coupled with other emotional stressors in a patient’s life, successful treatment of lymphedema is challenging. We present a case demonstrating how the physical and psychological aspects of care interplay, and, when well-managed, can positively affect the outcome.
