Over 40% of adults in the United States are considered obese. Obesity is known to cause abnormal metabolic effects and lead to other negative health consequences. Interestingly, differences in metabolism and contractile performance between obese and healthy weight individuals are associated with differences in skeletal muscle fiber type composition between these groups. Each fiber type is characterized by unique metabolic and contractile properties, which are largely determined by the myosin heavy chain isoform (MHC) or isoform combination that the fiber expresses. In previous studies, SDS-PAGE single fiber analysis has been utilized as a method to determine MHC isoform distribution and single fiber type distribution in skeletal muscle. Herein, a methodological approach to analyze MHC isoform and fiber type distribution in skeletal muscle was fine-tuned for use in human and rodent studies. In the future, this revised methodology will be implemented to evaluate the effects of obesity and exercise on the phenotypic fiber type composition of skeletal muscle.

Since 1975, the prevalence of obesity has nearly tripled around the world. In 2016, 39% of adults, or 1.9 billion people, were considered overweight, and 13% of adults, or 650 million people, were considered obese. Furthermore, Cardiovascular disease remains to be the leading cause of death for adults in the United States, with 655,000 people dying from related conditions and consequences each year. Including fiber in one’s dietary regimen has been shown to greatly improve health outcomes in regards to these two areas of health. However, not much literature is available on the effects of corn-based fiber, especially detailing the individual components of the grain itself. The purpose of this preliminary study was to test the differences in influence on both LDL-cholesterol and triglycerides between treatments based on whole-grain corn flour, refined corn flour, and 50% refined corn flour + 50% corn bran derived from whole grain cornmeal (excellent fiber) in healthy overweight (BMI ≥ 25.0 kg/m2) adults (ages 18 - 70) with high LDL cholesterol (LDL ≥ 120mg/dL). 20 participants, ages 18 - 64 (10 males, 10 females) were involved. Data was derived from blood draws taken before and after each of the three treatments as well as before and after each treatment’s wash out periods. A general linear model was used to assess the effect of corn products on circulating concentrations of LDL-cholesterol and triglycerides. From the model, it was found that the whole-grain corn flour and the 50% refined corn flour + 50% corn bran drive from whole grain cornmeal treatments produced a higher, similar benefit in reductions in LDL-cholesterol. However, the whole grain flour, refined flour, and bran-based fiber treatments did not influence the triglyceride levels of the participants throughout this study. Further research is needed to elucidate the effects of these fiber items on cardiometabolic disease markers in the long-term as well as with a larger sample size.

In this project I explored the relationship between Qigong and Tai Chi Easy meditative practices and cardiometabolic risk factors, specifically looking at obesity and stress. The meditative focus of Qigong and Tai Chi Easy was expected to improve cardiac vagal tone which should lead to decreases in the inflammatory effects of stress. Additionally, due to the decreases in the harmful effects of stress, we expect to see a decrease in obesity through decreases in BMI and in waist circumference.

Seven human subjects with body mass indices (BMIs) ranging from 19.4 kg/ m2 to 26.7 kg/ m2 and six human subjects with BMIs ranging from 32.1 kg/ m2 to 37.6 kg/ m2 were recruited and subjected to 45-minute bouts of acute exercise to look at the changes in the plasma concentration of the dopamine metabolite homovanillic acid (HVA) in response to acute physical activity. Plasma HVA concentration was measured before exercise and during the last 10 minutes of the exercise bout via competitive ELISA. On average the optical density (OD) of the samples taken from lean subjects decreased from 0.203 before exercise to 0.192 during exercise, indicating increased plasma HVA concentration. In subjects with obesity OD increased from 0.210 before exercise to 0.219 during exercise, indicating reduced plasma HVA concentration. These differences in OD were not statistically significant. Between the lean group and the group with obesity no significant difference was observed between the OD of the plasma samples taken before exercise, but a significant difference (p = 0.0209) was observed between the ODs of the samples taken after exercise. This indicated that there was a significant difference between the percent changes in OD between the lean group and the group with obesity, which suggested that there may be a body weight-dependent difference in the amount of dopamine released in response to exercise. Because of the lack of significance in the changes in OD within the lean group and the group with obesity the results of this study were insufficient to conclude that this difference is not due to chance, but further investigation is warranted.

Studies over the past years have collected data on the opinions of women in the workforce related to family planning and societal norms (Buddhapriya, 2009). However, these studies do not address the opinions of college students, the majority of whom have not yet entered the workforce yet, may have strong opinions about whether or not career ambitions and the desire for children are mutually exclusive. In addition, these studies mainly focus on the hardships of women already in the workforce, rather than to understand how to broaden the workforce to accommodate women before entering motherhood. Therefore, to encourage mothers in the workforce to strive for high professional achievement, it is important to first encourage those making life-changing decisions based on degree choice in college. In doing this, 111 Arizona State University (ASU) students of all years, gender, and college choice were surveyed to better understand the difference between men's and women’s opinions on family planning in relation to career. The results of the survey concluded that more women have not let family planning affect their choice of major and career aspirations. Although previous studies have shown that a job affects motherhood in the professional aspect, this does not seem to be a reason to alter career choices.

My thesis, titled Female Agency in the Canterbury Tales and Telling Tales, compares Geoffrey Chaucer’s fourteenth century work and Patience Agbabi’s modern adaptation in regards to their portrayal of female agency. While each work contained a whole selection of tales, I focus on four tales, which were The Miller’s Tale, The Clerk’s Tale, The Physician’s Tale, and The Wife of Bath’s Tale. I also include relevant historical information to support and assist in the analysis of the literary texts, and secondary sources were also used supplementarily to enhance the analysis. I argue that female agency is irrationally believed to be dangerous, and the consequent attempts at protection manifest as limitations, which are themselves damaging. The paper is divided into two main sections, which are themselves separated into three smaller categories. The first of the two main sections concerns what actions and options are available to women influenced by a distinction of gender; this section is divided into female gender ideals, marriage, and occupation. The second of the two main sections addresses the entities or individuals enacting the limitations upon female agency, and its three subsections are society, men, and women. I ultimately conclude that not only is it irrational to believe that female agency is dangerous, but also that making gender-based judgment on the capacity of a group of people or an individual is inherently flawed.
