Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn, Tallie Z. Baram

Psychology: Faculty Scholarship

Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body’s stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown. In this study, we used a …

Hyperglycemia (HG) stimulates the production of reactive oxygen species in the heart through activation of NADPH oxidase 2 (NOX2). This production is independent of glucose metabolism but requires sodium/glucose cotransporters (SGLT). Seven SGLT isoforms (SGLT1 to 6 and sodium-myoinositol cotransporter-1, SMIT1) are known, although their expression and function in the heart remain elusive. We investigated these 7 isoforms and found that only SGLT1 and SMIT1 were expressed in mouse, rat and human hearts. In cardiomyocytes, galactose (transported through SGLT1) did not activate NOX2. Accordingly, SGLT1 deficiency did not prevent HG-induced NOX2 activation, ruling it out in the cellular response to …

Factors Regulating Features Of Metabolic Syndrome, Sonja S. Pijut

Theses and Dissertations--Pharmacy

The collective presence of central obesity, low HDL-cholesterol, and elevated triglycerides, blood pressure, and fasting blood glucose constitutes Metabolic Syndrome (MetS), a disease state that increases the risk of cardiovascular disease (CVD) and Type 2 Diabetes Mellitus (T2DM). Nonalcoholic fatty liver disease (NAFLD), present in up to 90% of obese adults, is also linked to MetS. As in CVD, disruptions in cholesterol metabolism play a contributing role in the development of T2DM and NAFLD. Genes involved in cholesterol synthesis, secretion, and catabolism are diurnally regulated in the liver and adipose. Disruptions in the sleep-wake cycle are thought to potentiate metabolic …

The Postfinasteride Syndrome; An Overview, David L. Rowland, Ion G. Motofei, Florian Popa, Vlad D. Constantin, Adriana Vasilache, Ioana Păunică, Cristian Bălălău, Georgeta P. Păunică, Petrisor Banu, Stana Păunică

Journal of Mind and Medical Sciences

As a 5-α reductase inhibitor, Finasteride has proven effective in ameliorating two conditions documented to be androgen dependent, namely male androgenic alopecia and benign prostatic hyperplasia. Therapeutic results are maintained as long as the drug is administered, with treatment cessation generally leading to the return of symptomatology for each condition. In addition, during the therapeutic phase, several adverse effects have been reported, some of which persist long or indefinitely after treatment cessation, known as “post-finasteride syndrome.”

Herein we present and discuss the most common finasteride side effects, along with a psycho-neuroendocrine rationale that could explain the persistence of many adverse …

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a common genetic disease that leads to progressive renal cyst growth and loss of renal function, and is caused by mutations in the genes encoding polycystin-1 (PC1) and polycystin-2 (PC2), respectively. The PC1/PC2 complex localizes to primary cilia and can act as a flow-dependent calcium channel in addition to numerous other signaling functions. The exact functions of the polycystins, their regulation and the purpose of the PC1/PC2 channel are still poorly understood. PC1 is an integral membrane protein with a large extracytoplasmic N-terminal domain and a short, ~200 amino acid C-terminal cytoplasmic tail. …

Vitamin D Supplementation: Preventing Fractures, Courtney L. Carn, Michael S. Doherty

Physician Assistant Capstones, 2016 to 2019

Objective: To assess the ability of vitamin D supplementation in preventing musculoskeletal fractures. Methods: Systematic literature review using Google Scholar search terms “vitamin D supplementation” and “preventing hip fractures” from 2006-2015. Only RCTs, meta-analysis, and clinical guidelines were included. Results: Our search resulted in one meta-analysis and two randomized controlled trials. Conclusion: The summation of our investigation into vitamin D deficiency and the presence of musculoskeletal fractures has proven to be relatively inconclusive. The resulting data from our three studies did not provide any definitive proof that improved vitamin D levels correlates with better bone health.

Evaluation Of A Diabetes Self-Management Program For Hispanics In Lexington Kentucky: A Pilot Study, Miguel A. Gamboa Oropeza

Theses and Dissertations--Nutrition and Food Systems

Hispanics are more affected by diabetes than non-Hispanic whites and they tend to experience more severe complications. Research shows that although self-management is poor among ethnic minorities, it is even more so among Hispanics. The “Taking Ownership of Your Diabetes” (TOYD) program has been shown to be successful in helping individuals manage their diabetes. However, no work has been conducted with Hispanic audiences in Kentucky. TOYD program allows individuals to modify lifestyle risks and solve problems related to diabetes management. The program was translated from English to Spanish. Hispanics males and females between ages 19 to 75 years …

Effects Of Nox-1 Inhibition On Real-Time Blood Nitric Oxide And Hydrogen Peroxide In Acute Hyperglycemia, Ashley Mawhinney

PCOM Biomedical Studies Student Scholarship

Hyperglycemia has been associated with vascular endothelial dysfunction in part by a reduction in nitric oxide (NO) production and increased oxidative stress (e.g., increased superoxide (SO) and hydrogen peroxide (H₂O₂). Endothelial-derived NO can be significantly reduced by increased SO/H₂O₂ in part by the activation of NADPH oxidase during hyperglycemia. Of the 7 NADPH oxidase isoforms, NADPH oxidase isoform 1 (NOX1) is mainly expressed in the vasculature and may play a major role in hyperglycemia induced oxidative stress and vascular endothelial dysfunction. This hypothesis was tested by measuring blood NO and H2O2 levels in …

Pharmacy Faculty Articles and Research

Polycystic kidney disease (PKD) is the most common life-threatening genetic disease worldwide – affecting about 12.5 million people. Patients with the condition have multiple fluid-filled cysts in their kidneys that lead to a massive enlargement of the organ and gradual worsening of its function, as well as complete failure in many cases. The lack of available treatment means patients may eventually require regular dialysis or a kidney transplant.

• Analysis of genetic factors are still being discovered; however, this growing field may change the way medications are being prescribed for diabetes. This analysis investigated if pharmacogenetics is a useful tool for prescribing diabetic medications to T2DM patients. …

Liver Perilipin 5 Expression Worsens Hepatosteatosis But Not Insulin Resistance In High Fat-Fed Mice, Michelle B. Trevino, David Mazur-Hart, Yui Machida, Timothy King, Joseph Nadler, Elena V. Galkina, Arjun Poddar, Sucharita Dutta, Yumi Imai

Mathematics & Statistics Faculty Publications

Perilipin 5 (PLIN5) is a lipid droplet (LD) protein highly expressed in oxidative tissues, including the fasted liver. However, its expression also increases in nonalcoholic fatty liver. To determine whether PLIN5 regulates metabolic phenotypes of hepatosteatosis under nutritional excess, liver targeted overexpression of PLIN5 was achieved using adenoviral vector (Ad-PLIN5) in male C57BL/6J mice fed high-fat diet. Mice treated with adenovirus expressing green fluorescent protein (GFP) (Ad-GFP) served as control. Ad-PLIN5 livers increased LD in the liver section, and liquid chromatography with tandem mass spectrometry revealed increases in lipid classes associated with LD, including triacylglycerol, cholesterol ester, and phospholipid classes, …

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, …

Regulation Of Glucose Homeostasis By The Phlpp1 Phosphatase, Kara L. Larson

Theses and Dissertations--Molecular and Cellular Biochemistry

Type 2 diabetes mellitus is a metabolic disease that affects one in ten people in the United States. It is caused by a combination of genetics and lifestyle factors. Disease progression begins with insulin resistance in peripheral tissues followed by pancreatic beta-cell failure. The mechanisms behind disease progression are not completely understood. PH domain leucine rich repeat protein phosphatase 1 (PHLPP1) is a known regulator of Akt and other members of the AGC kinase family. Akt has been established to play a role in numerous metabolic signaling pathways, including insulin action. It is hypothesized that as a regulator of Akt, …

Comparison Of Electrogustometrically Determined Taste Threshold And Phenylthiocarbamide Sensitivity Between Non-Diabetic Subjects With First Degree Relatives With Type 2 Diabetes And Non-Diabetic Subjects Without Type 2 Diabetic First Degree Relatives, Matthew E. Joseph Do

PCOM Biomedical Studies Student Scholarship

Diabetes is a systemic degenerative disease, having adverse effects on many different organ systems. Nerve conduction specifically related to taste is one of the affected functions and can lead to altered taste perceptions and taste thresholds. Electrogustometry was used in this study to evaluate taste thresholds, and taste sensitivity was tested using phenylthiocarbamide-impregnated testing strips. Healthy non-diabetic subjects were divided into two experimental groups: One with a first degree relative with Type 2 diabetes and the other matched controls having no family history of Type 2 diabetes. The hypotheses: 1). There is a significant difference in taste threshold values and …

Study Of The Insulin Mimetic Sodium Orthovanadate In Glucosamine Induced Insulin Resistnace In Primary Rat Hepatocytes, Kalan Mcpherson

Masters Theses

Insulin resistance and type II diabetes is a disease state characterized by a lack of sensitivity of insulin to provoke a proper response in insulin sensitive tissues. Currently, we utilize glucosamine to increase flux through the Hexosamine Biosynthetic Pathway (HBP) to induce an insulin resistance like state in primary rat hepatocytes. We tested the effectiveness of the insulin mimetic sodium orthovanadate to determine if it could elicit an insulin-like response under these conditions. Mixed results were obtained on the effectiveness of vanadate as an insulin mimetic in this insulin resistant model.
