The Effects Of A Mobile Fitness Application On Weight Management And Physical Acticity Amongst University Students, Erica Deenihan
The Effects Of A Mobile Fitness Application On Weight Management And Physical Acticity Amongst University Students, Erica Deenihan
Evidence-Based Practice Project Reports
The prevalence of obesity, and obesity related diseases throughout America, specifically in regard to the college student population has steadily climbed over the course of the last forty years, due largely in part to the increase in sedentary lifestyle behaviors, amongst other factors (Swanson, 2016). Physical activity has been widely recognized as a valid means of combatting obesity and weight gain while promoting health related quality of life (Swanson, 2016). Therefore, implementing strategies aimed at increasing physical fitness in attempt to control weight management is imperative to promoting improved health outcomes. The purpose of this evidence-based project was to examine …
Mutagenic And Spectroscopic Investigation Of Ph Dependent Cooa Dna Binding, Brian R. Weaver
Mutagenic And Spectroscopic Investigation Of Ph Dependent Cooa Dna Binding, Brian R. Weaver
Chemistry Honors Papers
The carbon monoxide (CO) sensing heme protein, CooA, is a transcription factor which exists in several bacteria that utilize CO as an energy source. CooA positively regulates the expression of coo genes in the presence of CO such that the corresponding proteins may metabolize CO. The present studies have yielded the unexpected result that Fe(III) CooA binds DNA tightly at pH < 7, deviating from all previously reported work which indicate that CooA DNA binding is initiated only when the exogenous CO effector reacts with the Fe(II) CooA heme. This observation suggests that the disruption of one or more salt bridges upon effector binding may be a critical feature of the normal CooA activation mechanism. To test this possibility, several protein variants that eliminated a selected salt bridge for the CooA homolog from Rhodospirillum rubrum were prepared via site-directed mutagenesis. Samples of these variant proteins, which were overexpressed in Escherichia coli, were then characterized by spectroscopic methods and functional assays to investigate the impact these mutations had on CooA heme coordination …
A Simulation Of Anthropogenic Mammoth Extinction, Matthew Klapman
A Simulation Of Anthropogenic Mammoth Extinction, Matthew Klapman
Undergraduate Honors Papers
There are multiple hypotheses as to why the Columbian Mammoth (Mammuthus columbi) and other megafauna in North America went extinct relatively recently and relatively quickly. The most popular of which are disease, climate change, meteorite strikes, and over hunting by humans [2, 9]. There is evidence to show that a combination of factors contributed to the megafaunal extinction, but ”overkill” explores the idea that early humans migrated onto the continent and then hunted the mammoths and other megafauna to extinction. The overkill hypothesis was first proposed by anthropologist Paul Martin in 1973 [8]. Evidence from radiocarbon dating shows that the …
The Effects Of 12 Weeks Of Instructor-Led Yoga Classes On Balance In Older Adults, Patricia C. Hart
The Effects Of 12 Weeks Of Instructor-Led Yoga Classes On Balance In Older Adults, Patricia C. Hart
Evidence-Based Practice Project Reports
Participation in a regular exercise program is an effective way to reduce and/or prevent a number of functional declines associated with aging (Chodzko-Zajo et al., 2009). Older adults are advised to participate in regular aerobic activity and practice muscle strengthening activities and exercise that maintains or improves balance (U.S. Department of Health and Human Service, [USDHHS], 2012). Less than one third of older adults engage in 30 minutes of low to moderate intense physical activity at least five days a week as recommended in current guidelines (USDHHS, 2012), and these guidelines fail to address losses in strength and flexibility seen …
