Field Testing Adolescent Females For Cardiovascular Disease Risk, C. Jayne Brahler, Wesley R. Stephens, Betsy Donahoe Fillmore

Physical Therapy Faculty Publications

Over-fatness and poor cardiovascular (CV) fitness are well-documented risk factors for cardiovascular disease (CVD) in adults, but less is known about their association with disease risk in adolescents. This study aimed to determine the relationship between anthropometrics, fitness, and CVD risk.

Six anthropometric indicators of body fatness, seven measures of fitness, and seven metabolic and hemodynamic CVD risk factors were measured in a convenience sample of 28 female high school students (15-18 years of age). A tally was made of the number of factors for which each subject was outside the normal reference range (CVD risk).

Correlation analyses were completed …

Arteriogenic Revascularization Does Not Induce Vascular Function Impairment, Matthew David Yocum

Master's Theses

Functional hyperemia and arteriolar vasodilation are impaired with chronic ischemia. We sought to examine the impact of chronic ischemia on collateral artery function. For this we used two hindlimb ischemia models to dissect the impact of different repair processes on collateral function. Ligation of the femoral artery increases shear stress in the muscular branch and results in outward remodeling and arteriogenesis. In contrast, resection of the femoral artery proximal to the muscular branch induces blood flow divergence and neutral remodeling along with expectedly greater hypoxia and inflammation. On day 14 after each surgery the diameter of the muscular branch was …

Regulation Of Alginate Production Of Pseudomonas Aeruginosa Pseudomonas Aeruginosa, Fredrick Heath Damron

Theses, Dissertations and Capstones

Pseudomonas aeruginosa (P.a.) is a major threat to the health and well being of a person living with cystic fibrosis (CF). P.a. is capable of conversion to mucoidy or alginate overproducing phenotype. Mucoidy facilitates the chronic infection of P.a. infection in the CF lung. Mutations in the anti-sigma factor mucA, result in activation of the sigma factor AlgU which promotes expression of alginate through the alginate biosynthetic operon. However, P.a. can produce alginate independent of mucA mutation via a mechanism known as regulated proteolysis. Proteases AlgW and MucP can degrade MucA to liberate and activate AlgU. In this dissertation, two …

Beliefs And Practices Of Expert Respiratory Care Faculty On Critical-Thinking Learning: A Case Study, James Leland Hulse

Dissertations

Problem. The development of critical-thinking skills during the professional training of respiratory therapists is imperative for good practice. Research evidence suggests that interactive instructional strategies are far more effective than traditional lectures. Missing from the literature are thick descriptions of how faculty organize the delivery of respiratory therapy curriculum to develop critical thinking. This case study describes the beliefs and practices of faculty members in an academically strong program in view of developing critical thinking.

Method. A qualitative, single case-study design was used to identify critical-thinking strategies and beliefs incorporated by the faculty. The program was nominated by expert members …
