Nutrition Needs Assessment For Women Of Childbearing Age With Polycystic Ovarian Syndrome, Callie Coleman, Whitney Bignell

Undergraduate Honors Theses

Polycystic Ovarian Syndrome (PCOS) is an endocrine disorder that affects women’s menstrual cycles, androgen (male hormones) levels, and cysts on the ovaries. This endocrine disorder has various symptoms, with insulin resistance as a hallmark symptom. Approximately 65-70% of women with PCOS have insulin resistance and hyperinsulinemia, whether or not they are overweight, obese, or lean (Marshall & Dunaif, 2012). Many women with PCOS struggle to lose weight because their excess weight is related to nutrition, lifestyle factors, and imbalanced hormones. Understanding PCOS as a metabolic disorder with nutritional implications led to investigating the potential benefit of having registered dietitian nutritionists …

Management Of Type 1 Diabetes: A Family Affair, Emily Grubbs

Southeastern Council on Family Relations Conference

People who live with Type 1 diabetes (T1D) have to carefully self-administer insulin to keep blood glucose levels in a safe healthy range – a complex and demanding task (WHO, 2016). Social support has been found to alleviate diabetes-stress and increase management behaviors (Mackey et al., 2016). Social support from family members is especially advantageous, however currently no single family-based intervention has been established to show reliable improvements in T1D outcomes (Rosland et al., 2010). A review of the literature reveals that social support promoting autonomy is associated with the best T1D outcomes; social support that undermines autonomy is associated …

Divergent Relationship Of Circulating Ctrp3 Levels Between Obesity And Gender: A Cross-Sectional Study, Roy Marshall Wagner, Kamesh Sivagnanam, W. Andrew Clark, Jonathan M. Peterson

C1q TNF Related Protein 3 (CTRP3) is a novel adipose tissue derived secreted factor, or adipokine, which has been linked to a number of beneficial biological effects on metabolism, inflammation, and survival signaling in a variety of tissues. However, very little is known about CTRP3 in regards to human health. The purpose of this project was to examine circulating CTRP3 levels in a clinical population, patients with symptoms requiring heart catheterization in order to identify the presence of obstructive coronary artery disease (CAD). It was hypothesized that serum CTRP3 levels would be decreased in the presence of CAD.

Identification Of Putative Receptors For The Novel Adipokine Ctrp3 Using Ligand-Receptor Capture Technology, Ying Li, Tammy Ozment, Gary L. Wright, Jonathan M. Peterson

ETSU Faculty Works

C1q TNF Related Protein 3 (CTRP3) is a member of a family of secreted proteins that exert a multitude of biological effects. Our initial work identified CTRP3’s promise as an effective treatment for Nonalcoholic fatty liver disease (NAFLD). Specifically, we demonstrated that mice fed a high fat diet failed to develop NAFLD when treated with CTRP3. The purpose of this current project is to identify putative receptors which mediate the hepatic actions of CTRP3.

Methods

We used Ligand-receptor glycocapture technology with TriCEPS™-based ligand-receptor capture (LRC-TriCEPS; Dualsystems Biotech AG). The LRC-TriCEPS experiment with CTRP3-FLAG protein as ligand and insulin as a …

Prenatal Exposure To Perfluoroalkyl Acids And Serum Testosterone Concentrations At 15 Years Of Age In Female Alspac Study Participants, Mildred Maisonet, Antonia M. Calafat, Michele Marcus, Jouni J.K. Jaakkola, Hany Lashen

ETSU Faculty Works

Background: Exposure to perfluorooctane sulfonic acid (PFOS) or to perfluorooctanoic acid (PFOA) increases mouse and human peroxisome proliferator–activated receptor alpha (PPARα) subtype activity, which influences lipid metabolism. Because cholesterol is the substrate from which testosterone is synthesized, exposure to these substances has the potential to alter testosterone concentrations.

Objectives: We explored associations of total testosterone and sex hormone–binding globulin (SHBG) concentrations at age 15 years with prenatal exposures to PFOS, PFOA, perfluorohexane sulfonic acid (PFHxS), and perfluoronanoic acid (PFNA) in females.

Methods: Prenatal concentrations of the perfluoroalkyl acids (PFAAs) were measured in serum collected from pregnant mothers at enrollment (1991–1992) …

Effect Of Obesity And Exercise On The Expression Of The Novel Myokines, Myonectin And Fibronectin Type Iii Domain Containing 5, Jonathan M. Peterson, Ryan Mart, Cherie E. Bond

ETSU Faculty Works

Metabolic dysfunction in skeletal muscle is a major contributor to the development of type 2 diabetes. Endurance exercise training has long been established as an effective means to directly restore skeletal muscle glucose and lipid uptake and metabolism. However, in addition to the direct effects of skeletal muscle on glucose and lipids, there is renewed interest in the ability of skeletal muscle to coordinate metabolic activity of other tissues, such as adipose tissue and liver. The purpose of this study was to examine the effects of endurance exercise on the expression level of two novel muscle-derived secreted factors, or myokines, …
