Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell Aug 2019

Influence Of Heating And Biological Sex On Vascular Dysfunction Associated With Long-Duration Sitting And Standing, Aaron Richard Caldwell

Graduate Theses and Dissertations

Purpose: The purpose of these studies was to determine if arterial angulations (through sitting or standing), shear stress (through local heating), or a combination of these factors affected vascular function. Moreover, this studied estimated the magnitude of the effect that biological sex has on these vascular responses. Methods: Twenty-six healthy, young (18-40 years old) males (n=13) and females (n=13) completed two experimental trials (2-h sitting and 2-h standing). In a randomized fashion, one leg was passively heated in order to increase shear rate. Following a 48-h washout, participants returned to the laboratory to complete the other trial. Flow-mediated dilation (FMD) …


Can Antioxidant-Rich Berries Improve Risk Factors Associated With Cardiovascular Disease In Postmenopausal Smokers?, Jordan Alaine Teeple Dec 2011

Can Antioxidant-Rich Berries Improve Risk Factors Associated With Cardiovascular Disease In Postmenopausal Smokers?, Jordan Alaine Teeple

Graduate Theses and Dissertations

The purpose of this study was to examine the effects of smoking on risk factors associated with cardiovascular disease (CVD) and determine the efficacy of antioxidant-rich berries in ameliorating these risk factors in postmenopausal smokers. Menopause and cigarette smoking have been identified as major risk factors for CVD due to a decrease in antioxidant protection, increase in inflammation and oxidative stress, and adverse changes in serum lipids. Antioxidants, specifically flavonoid compounds found in blackberries and blueberries, have been shown to prevent low-density lipoprotein cholesterol oxidation and thus prevent downstream inflammation and oxidative stress. Healthy, postmenopausal nonsmokers (n=14) and smokers (n=31) …


Developing Enterprise Budgets For Sustainable School Gardens: Service Learning In A Global Context, Ashley D. Jones, Jennie S. Popp Jan 2009

Developing Enterprise Budgets For Sustainable School Gardens: Service Learning In A Global Context, Ashley D. Jones, Jennie S. Popp

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Service learning programs are becoming a part of curricula in universities throughout the United States. The University of Arkansas, Fayetteville, (UAF) established a service learning program that targeted the educational, health, social, and agricultural needs of a community. The focus of this research aimed to provide students, faculty, community members, school officials, and students with a template for crop budgets. These crop budgets are used to evaluate the costs and returns of producing multiple crops at a school. Crops produced in a sustainable garden must meet three criteria: 1) have minimal negative environmental impact, 2) provide just-in-time production of quality …
