Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
Ten algal isolates were obtained from soil into axenic culture and placed into defined media containing from 0 to 50 ppm of DDT, 2, 4-D,2,4,5-T, rotenone, or malathion (in two purities, 95 and 99%). For nine of the isolates, growth was measured...
Premenopausal women have fewer and less severe strokes when compared to postmenopausal females and aged matched males. The most obvious factor that could account for the observed difference is the physiological activity of Estrogen. Numerous...

This work presents a novel comprehensive effort to understand the fluid dynamics within orbiting dishes and the effects of the resulting oscillating fluid flow on shear and endothelial cellular responses within the dishes. It is well documented...
Crossover design is a type of longitudinal study with each subject receiving different treatments in different time periods. It has been used frequently in the pharmaceutical industry and other medical fields to investigate the safety and efficacy...
The fundamental question of the exact nature of the role played by TNF in the failing myocardium remains one of contention. Many preclinical studies have demonstrated beneficial effects with TNF antagonism and recently the dichotomous role played...
This study compared brief, single sessions of physical activity (PA, self-paced treadmill walking) and relaxation/meditation (R/M, the "Body Scan") on positive and negative affect and anxiety measures in female undergraduates. Both were...
The current study examined how Disclosure, Stereotype Disconfirming Information, and Stereotype Disconfirming Information and Disclosure Combined) influences an individual's stigma (stereotype endorsement, emotional reactions, and discrimination)...
This dissertation explores the physical and biological factors that control zooplankton population growth rates in the Ohio River (USA). I employed both observational studies and a mesocosm experiment to ascertain zooplankton population and...

The purpose of this study was to compare the differences between 2 sets of ballistic stretching and 2 sets of a dynamic stretching routine on vertical jump performance. The intraclass reliability coefficients for maximum jump height, force, and...
Algebra--Study and teaching (Secondary); Motivation in education; Feedback (Psychology)
The double-blind study used two intact ninth grade high school Algebra One classes for a total sample size of 46. Within each of the classes the participants were assigned randomly to one of three treatment groups: self-referenced feedback,...
Arsenic--Physiological effect; Cardiovascular system--Diseases; Liver--Effect of arsenic on; Arsenic--Toxicology
Chronic arsenic exposure is associated with increased cardiovascular disease (CVD). Prenatal arsenic exposure at 49 ppm arsenic accelerates atherosclerosis underlying CVD in ApoE-/- mice, but the mechanism is unknown. This dissertation examines the...
Green tea--Health aspects; Green tea--Therapeutic use; Polyphenols--Physiological effect; Drug delivery systems; Lungs--Cancer--Treatment
Green tea polyphenols (GTPs) are gaining increasing attention because of their potential anti-tumor effects. However, poor oral bioavailability limits their efficacy in vivo. In this dissertation, two hypotheses were tested: 1) GTPs administered...
Menthol has been regularly utilized as a treatment in sports related injuries for many years, yet little is known about its physiological interactions or its effect on performance. Our previous study indicates that topically applied menthol may...
