Assessment Of The Interplay Between Regional Β-Amyloid Burden And White Matter Hyperintensities On Cognition And Default Mode Network In Clinically Normal Older Participants, Doaa G. Ali
Theses and Dissertations--Clinical and Translational Science
Objective: Alzheimer’s disease (AD) and subcortical vascular dementia are considered the most common pathologic contributors to dementia in the aging population. Both frequently coexist in over 80% of community dwelling adults with dementia. The neuropathological development of AD arguably begins with β-amyloid (Aβ) deposition in the brain. This series of studies aims to test the hypothesis that early focal regional amyloid deposition in the brain is associated with cognitive performance in specific cognitive domain scores in preclinical AD (pAD) (study1). Since mixed dementia is widely recognized as the norm rather than the exception, the second study aimed to explore the …
Utilizing Patient-Derived Epithelial Ovarian Cancer Tumor Organoids To Predict Carboplatin Resistance, Justin W. Gorski
Utilizing Patient-Derived Epithelial Ovarian Cancer Tumor Organoids To Predict Carboplatin Resistance, Justin W. Gorski
Theses and Dissertations--Clinical and Translational Science
The development of patient-derived tumor organoids (TOs) from epithelial ovarian cancer tumor obtained at the time of primary or interval debulking surgery has the potential to play an important role in precision medicine.
Here, we utilize TOs to test front-line chemotherapy sensitivity and to investigate genomic drivers of carboplatin resistance. We developed six high grade serous epithelial ovarian cancer tumor organoids from tissue obtained during debulking surgery (2 neoadjuvant carboplatin exposed, 4 chemo-naïve). Each organoid line was screened for sensitivity to carboplatin at four different doses (100, 10, 1 and 0.1µM). Cell viability curves and resultant EC50 values were determined …
A Pilot Study Of A Multiple Health Behavior Change Intervention For Smokers, Srihari Seshadri
A Pilot Study Of A Multiple Health Behavior Change Intervention For Smokers, Srihari Seshadri
Theses and Dissertations--Clinical and Translational Science
Background: Being both obese and a smoker increases the probability of developing type 2 diabetes, cardiovascular disease, and cancer, diseases that impact Kentucky residents disproportionately. Kentucky (KY) has a high incidence of obesity (34.2%) and smoking (24.5 %). Weight gain associated with smoking cessation also can undermine health benefits of quitting, and may lead to smoking relapse.
Aim: The aim of the pilot study was to implement and evaluate a Multiple Health Behavioral Change (MHBC) program that combines Cooper Clayton Method to Stop Smoking (CCMSS) and the Diabetes Prevention Program (DPP) for weight control.
Method: A 15-week intervention was administered …
The Role Of Fat Grafting And Adipose-Derived Stem Cells In Breast Reconstruction, Krishna S. Vyas
The Role Of Fat Grafting And Adipose-Derived Stem Cells In Breast Reconstruction, Krishna S. Vyas
Theses and Dissertations--Clinical and Translational Science
Fat grafting is a common surgical procedure that involves the transfer of fat from one area of the body to another in order to improve contour deformities, such as in breast reconstruction. Advantages of the technique include using autologous tissue rather than a foreign body and the added benefit of having liposuction to remove fat from an undesirable location. Although adipose tissue could be the ideal soft tissue filler, fat grafting is plagued by tremendous variability in long-term retention, with volume survival rates of 20-80%, resulting in suboptimal outcomes and repetitive procedures.
The mechanisms contributing to long-term fat graft survival …
The Metabolomic Effects Of Metformin On Colon Cancer, Jennifer W. Harris
The Metabolomic Effects Of Metformin On Colon Cancer, Jennifer W. Harris
Theses and Dissertations--Clinical and Translational Science
Metformin is an oral biguanide that is prescribed to over 120 million people worldwide for the treatment of conditions including type II diabetes mellitus, polycystic ovarian syndrome, and gestational diabetes. This hypoglycemic agent is rapidly emerging as a potential cost-effective anti-oncogenic agent. Over the past decade multiple epidemiologic studies have consistently associated metformin with decreased cancer incidence and cancer-related mortality. More recently numerous preclinical and clinical studies have demonstrated anti-cancer effects of metformin, leading to the proposal of numerous clinical trials to better understand this drug and its mechanism of action.
Previously experts believed metformin primarily targeted AMP-activated protein kinase …
Primary And Secondary Prevention Of Hepatitis C Virus Among Rural Appalachian People Who Use Drugs, Dustin B. Stephens
Primary And Secondary Prevention Of Hepatitis C Virus Among Rural Appalachian People Who Use Drugs, Dustin B. Stephens
Theses and Dissertations--Clinical and Translational Science
Hepatitis C virus (HCV) remains a major cause of morbidity and mortality worldwide, with 3% of the global population chronically infected. Clinical impacts in the United States are projected to increase for two decades, and mortality attributed to HCV now exceeds HIV. Injection drug use (IDU) is the most common route of transmission in the developed world. Advances in treatment offer hope of mitigating HCV impacts, but substantial barriers obstruct people who inject drugs (PWID) from receiving care, particularly in medically underserved regions including Central Appalachia. This study assessed IDU paraphernalia sharing longitudinally over 24 months in a sample of …
