Exogenous Ubiquitin: Role In Myocardial Inflammation And Remodeling Post- Ischemia/Reperfusion Injury, Stephanie Scofield
Electronic Theses and Dissertations
Sympathetic stimulation occurs in the heart after injuries such as ischemia/reperfusion (I/R) and myocardial infarction and affects myocardial remodeling. Prolonged sympathetic stimulation can result in myocardial dysfunction through its effects on cardiac myocyte apoptosis and myocardial fibrosis. Ubiquitin (UB) is well known for its role of tagging old or damaged proteins for degradation via the UB-proteosome pathway. The role of exogenous UB however, is not fully understood. Previously, our lab showed that β-adrenergic receptor (β-AR) stimulation increased levels of extracellular UB in the conditioned media of adult rat ventricular myocytes and that UB inhibits β-AR-stimulated apoptosis. This study investigates the …

Cellular Mechanisms Of Ionoregulation In The Gill Of Japanese Medaka And Rainbow Trout, Rebecca Jo Bollinger
Graduate Theses and Dissertations
Euryhaline fishes are capable of adapting to a wide range of salinities such as freshwater, brackish water or seawater. Through the combined effort of the gill, kidney and intestine, they are able to osmoregulate to maintain a constant internal hydromineral balance. As the gill is in direct contact with the external environment, it is continuously working to maintain ion and acid/base balance, gas exchange and eliminate nitrogenous waste. Fish in freshwater are subjected to osmotic water gain and diffusional ion loss across the gill and experience the opposite in seawater. Therefore, the gill exhibits extreme plasticity when experiencing a change …

The Effects Of Selection For High Voluntary Wheel-Running Behavior On Nutrient Canal Abundance And Size, Nicolas Lawrence Schwartz
Electronic Theses, Projects, and Dissertations
Variations in skeletal morphology have often been used to interpret an organism’s overall activity level when direct observation is not possible. Although skeletal change in response to exercise is well documented, the skeleton’s response to mechanical loading is modulated by several factors (e.g. age, hormones, sex). Additionally, variation in skeletal morphology is partially a result of genetic variation, which is rarely accounted for in inferences of locomotor activity from skeletal remains. However, blood flow to long bones serves as a proxy for bone metabolic activity, which can be used to infer locomotor activity. Long bones receive blood from three sources, …

UNLV Theses, Dissertations, Professional Papers, and Capstones
Volunteerism and work are topics which academics in several disciplines research. This study is an examination of the intersection of work and volunteerism via the lens of role theory. According to role theorists, the term role refers to behaviors which are either a result of social position or expectations (Biddle 1986). Cognitive role theorists use vocabulary such as “role conflict” and “role overload” to identify incongruences sometimes found in roles individuals have in their lives (Biddle 1986). These incongruences are primarily examined as they relate to individual level consequences. This research explores volunteerism and work as they relate to role …

Dietary Intake And Energy Expenditure Of Pararescuemen During Routine Training, Andrea Woita
UNLV Theses, Dissertations, Professional Papers, and Capstones
Pararescuemen are one group of Air Force Special Operations Forces (SOF) who engage in vigorous physical training to achieve mission readiness. This type of training requires high energy expenditures and matching dietary intake to support basic physiological needs and to meet performance demands. However, few studies have investigated the energy expenditure and dietary intake of SOF and none have specifically examined these behaviors in Pararescuemen. The goal of this investigation was to determine the energy expenditure and dietary intake of Pararescuemen during routine training - a period when these operators receive supervision and guidance for performance improvements, recovery, and career …

The Effects Of Overfeeding On Body Composition: The Role Of Macronutrient Composition - A Narrative Review, Alex Leaf, Jose Antonio
International Journal of Exercise Science
International Journal of Exercise Science 10(8): 1275-1296, 2017. Compared to investigations on hypocaloric diets, the effects of chronic overfeeding have been less studied. It has been posited that consuming calories in excess of daily caloric requirements will result in a gain in body weight and in particular fat mass regardless of which macronutrient(s) are consumed. However, recent evidence suggests that there is a quantitative difference in protein versus carbohydrate and/or fat overfeeding as it relates to body composition. Protein overfeeding or the consumption of a high protein diet may not result in a gain in body weight or fat mass …
