Cardiovascular Health Among Us And Argentine University Students: A Comparative Study Of Behaviors And Risk Factors, Gina Fitzgerald, Gabriella Smith Mar 2014

Cardiovascular Health Among Us And Argentine University Students: A Comparative Study Of Behaviors And Risk Factors, Gina Fitzgerald, Gabriella Smith

Seaver College Research And Scholarly Achievement Symposium

Cardiovascular disease for some time has been the leading cause of death in the Western world. Primary prevention is the only way to halt the onset of cardiovascular disease, yet there is little information on the prevalence of risk factors for cardiovascular disease in young adults. This study seeks to evaluate students from the Catholic University of Argentina and Pepperdine University of America for the prevalence of CVD risk factors, as well as knowledge of CVD and daily habits that contribute to heart health. Thus we compared two cultures with very different lifestyles and prevalence of risk factors. We hypothesized …


The Effect Of Shear Stress, Potassium, And Adenosine On Α-1 Adrenergic Vasoconstriction Of Rat Soleus Feed Arteries, Tanner J. Heckle Mar 2014

The Effect Of Shear Stress, Potassium, And Adenosine On Α-1 Adrenergic Vasoconstriction Of Rat Soleus Feed Arteries, Tanner J. Heckle

Seaver College Research And Scholarly Achievement Symposium

During exercise, sympathetic nerve activity increases, augmenting the release of the neurotransmitter norepinephrine (NE) at the arterial wall and into the blood. NE binds to arterial adrenergic receptors to cause vasoconstriction, yet arteries in contracting skeletal muscle dilate during exercise. Previous evidence from Ives et al. suggests that heat and acidosis may partially inhibit constriction resulting from α-1 adrenergic receptors (termed sympatholysis). Our lab has previously demonstrated that rat soleus feed arteries respond to sympathetic signaling solely by α-1 adrenoceptors. We hypothesized that increased levels of arterial wall shear stress, potassium, or adenosine also contribute to sympatholysis, thereby reducing sympathetic …
