Exploring The Glucocorticoid Actions Of 1Α-Hydroxycorticosterone (1Α-Oh-B) In The Elasmobranch Fishes, Faith Nichole Lambert Dec 2014

Exploring The Glucocorticoid Actions Of 1Α-Hydroxycorticosterone (1Α-Oh-B) In The Elasmobranch Fishes, Faith Nichole Lambert

Master's Theses

The corticosteroid 1α-hydroxycorticosterone (1α-OH-B) is unique to the elasmobranch fishes. It is thought that 1α-OH-B acts as both the primary glucocorticoid (GC) and mineralocorticoid (MC) in these fishes, a dual role analogous to that of cortisol in the teleost fishes. The MC characteristics of 1α-OH-B are well supported, but data supporting its GC functions are lacking. In this study, the putative GC actions of 1α-OH-B were examined. The first experiment characterized the physiological stress response of the Atlantic stingray (Dasyatis sabina) to air exposure, with particular regards to the roles of corticosteroids and metabolic fuels. Results demonstrate that …


A Comparison Of Fatigue During Cardiocerebral Resuscitation With Different Compression Rates Among Layperson And Professional Rescuers, Christopher Cassidy Aug 2014

A Comparison Of Fatigue During Cardiocerebral Resuscitation With Different Compression Rates Among Layperson And Professional Rescuers, Christopher Cassidy

Master's Theses

Quality chest compressions during Cardiopulmonary Resuscitation (CPR) are vital to maintaining adequate perfusion of oxygenated blood to the organs of the body to sustain life. Over the years, the compression rate recommended in Basic Life Support (BLS)/ Advanced Cardiac Life Support (ACLS) protocols for the best possible outcome has risen, and with that increase there are questions regarding rescuer fatigue and the effectiveness of compressions. Layperson and professional rescuers, answering to an emergency, both maintain continuous chest compressions until advanced life support arrives. Depending on the location, this arrival time would most likely be longer than the two minute standard …


Effectiveness Of A Football Over Helmet Padding System In Reducing Peak Acceleration Of The Head And Severity Index 2014, Nicole Cuccurullo Jun 2014

Effectiveness Of A Football Over Helmet Padding System In Reducing Peak Acceleration Of The Head And Severity Index 2014, Nicole Cuccurullo

Master's Theses

The purpose of this study was to determine if: (a) a football helmet equipped with the Guardian Cap meets the National Operating Committee on Standards for Athletic Equipment (NOCSAE) football helmet standards and (b) if the Severity Indexes and peak accelerations produced during the NOCSAE impact tests were smaller for a football helmet equipped with the Guardian Cap over-helmet padding system than for the same helmet without the Guardian Cap. A total of 54 drop impact tests were completed, 27 on the football helmet alone and 27 on the football helmet equipped with the Guardian Cap. Tests were completed on …


Physical Activity And Nutritional Behavior Of Overweight College Students Trying To Lose Weight 2014, Santino Vallejos M.S. May 2014

Physical Activity And Nutritional Behavior Of Overweight College Students Trying To Lose Weight 2014, Santino Vallejos M.S.

Master's Theses

Although there are numerous benefits to increased physical activity and proper dietary behaviors, the decreased participation in physical activity and poor dietary behaviors has emerged as a significant problem within the college student population. The focus of this research study was to identify the relationship between physical activity and dietary behavior to weight loss behaviors within an undergraduate student sample of a small, comprehensive northeastern university. College-aged students (age range: 17 to 27 years old) completed the American College Health Association’s (ACHA) National College Health Assessment II (NCHA) during the years 2009 and 2012. According to the results, there were …


The Quadmill: Effects Of Eccentric Training Vs. Concentric Training On Lower Extremity Power And Anaerobic Capacity 2014., John Crosby May 2014

The Quadmill: Effects Of Eccentric Training Vs. Concentric Training On Lower Extremity Power And Anaerobic Capacity 2014., John Crosby

Master's Theses

Training focuses on the concentric action of muscle during exercise for most exercise programs, but eccentric training may yield greater results. The QuadmillTM is a unique piece of training equipment that focuses on training the quadriceps muscle eccentrically. Purpose: to determine if using the QuadmillTM could increase power and anaerobic capacity to the same level, if not greater, than a standard concentric focused lower body training protocol. Participants were 44 undergraduate college students (24 Male 20 Female) Design: participants placed into three equal groups (QuadmillTM, Lifting, Control). The two experimental groups (QuadmillTM and Lifting) underwent …
