Obesity has become a worldwide epidemic and is a major risk factor for metabolic syndrome. Oxidative stress is known to play a role in the generation and maintenance of an obesity phenotype in both isolated adipocytes and intact animals. Because we had identified that the Na/K-ATPase can amplify oxidant signaling, we speculated that a peptide designed to inhibit this pathway, pNaKtide, might ameliorate an obesity phenotype. To test this hypothesis, we first performed studies in isolated murine preadipocytes (3T3L1 cells) and found that pNaKtide attenuated oxidant stress and lipid accumulation in a dose-dependent manner. Complementary experiments in C57Bl6 mice ...

eGEMs (Generating Evidence & Methods to improve patient outcomes)

Introduction: Self-reporting by patients though the use of electronic patient-reported outcome (PRO) measures has been shown to use increase patient satisfaction with care, improve patient-provider communication, symptom management, and health quality. Additionally, PROs are increasingly used in research to expand understanding regarding the relative risks, benefits, and burdens of interventions. While experience embedding patient-reported outcomes (PROs) into registries and clinical workflow is growing, there is little in the literature to guide those interested in incorporating PROs into routine clinical care and for use in research.

The Design Of An Instrument To Assess Clinical Laboratories Efficacy Post Implementation Of The Patient Protection Affordable Care Act, Harry McDonald Jr. 2017 University of Southern Mississippi

The Design Of An Instrument To Assess Clinical Laboratories Efficacy Post Implementation Of The Patient Protection Affordable Care Act, Harry Mcdonald Jr.

Dissertations

The healthcare system in the United States has undergone substantial changes in support of the Patient Protection and Affordable Care Act (PPACA). On March 23, 2010, the implementation of the new healthcare law brought universal healthcare access to all Americans, while attempting to increase quality and decrease medical costs. The new law promotes more of a quality-focused, outcome-based model rather than a pay-for-fee service model; thus, moving the paradigm from infrequent to preemptive healthcare. The PPACA postulates as the only way to achieve cost savings while increasing quality and access. Never before has there been such an extensive change to ...

Undergraduate Research On General Aviation Hypoxia: A Student’S Perspective, Claire Schindler 2017 Embry-Riddle Aeronautical University

Undergraduate Research On General Aviation Hypoxia: A Student’S Perspective, Claire Schindler

Discovery Day - Prescott

During the fall academic term of 2016, an opportunity arose through the College of Aviation to serve as an undergraduate research assistant. Through discussion with faculty mentors, it was decided that a severely overlooked aspect of the aviation industry was survivors of hypoxia, especially in the less regulated general aviation community. The problem this study addresses is the uncertainty of the common circumstances that general aviation pilots find themselves in that create a hypoxic state, as well as whether or not that pilot reported the occurrence to the proper establishments. The results of this study showed not only those that ...


Investigation Of Radiation Injury In The Esophagus From Definitive Chemoradiation Therapy Using Novel Imaging Biomarkers, Joshua S. Niedzielski 2016 The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Investigation Of Radiation Injury In The Esophagus From Definitive Chemoradiation Therapy Using Novel Imaging Biomarkers, Joshua S. Niedzielski

UT GSBS Dissertations and Theses (Open Access)

Radiation injury in the esophagus occurs with high frequency from the treatment of non-small cell lung cancer (NSCLC). Radiation esophagitis is an acute normal tissue toxicity that negatively affects treatment efficacy by limiting dose and potentially interrupting radiation therapy. Clinical quantification of this toxicity is typically achieved by utilizing physician grading scales, assigning complication severity on an ordinal scale of symptom presentation and/or physician chosen interventions. These criteria are subjective in nature, both from the physician assigning the grade and the patient reporting the symptom. Furthermore, radiation therapy planning guidelines for the esophagus are derived from toxicity prediction models ...

Faculty papers Farber Institute for Neurosciences

Aberrant hexanucleotide repeat expansions in C9orf72 are the most common genetic change underlying amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). RNA transcripts containing these expansions undergo repeat-associated non-ATG translation (RAN-T) to form five dipeptide repeat proteins (DPRs). DPRs are found as aggregates throughout the CNS of C9orf72-ALS/FTD patients, and some cause degeneration when expressed in vitro in neuronal cultures and in vivo in animal models. The spread of characteristic disease-related proteins drives the progression of pathology in many neurodegenerative diseases. While DPR toxic mechanisms continue to be investigated, the potential for DPRs to spread has yet to be ...


Continuous Care In Complex Contexts: Access To Health Services For Noncommunicable Diseases Among Syrian Refugee Women In Jordanian Host Communities, Jennifer Ostrowski 2016 SIT Study Abroad

Continuous Care In Complex Contexts: Access To Health Services For Noncommunicable Diseases Among Syrian Refugee Women In Jordanian Host Communities, Jennifer Ostrowski

Independent Study Project (ISP) Collection

This study examines how, when and where Syrian refugee women living in a host community in central Jordan access health services related to noncommunicable diseases. Noncommunicable diseases are the leading cause of death and disability worldwide, but can be effectively managed through timely treatment. Examining access to care for these diseases in the context of humanitarian emergencies, such as war and displacement, is particularly important because they require continuous care, which may be interrupted during emergencies, and because they can cause acute complications, which may be exacerbated by emergencies (WHO, 2016).

Previous studies indicate a high burden of NCDs among ...


Sample Size Formulas For Estimating Intraclass Correlation Coefficients In Reliability Studies With Binary Outcomes, Mengxiao Xu 2016 The University of Western Ontario

Sample Size Formulas For Estimating Intraclass Correlation Coefficients In Reliability Studies With Binary Outcomes, Mengxiao Xu

Electronic Thesis and Dissertation Repository

Introduction: Measurement errors can seriously affect quality of clinical practice and medical research. It is therefore important to assess such errors by conduct- ing studies to estimate a coefficients reliability and assessing its precision. The intraclass correlation coefficient (ICC), defined on a model that an observation is a sum of information and random error, has been widely used to quantify reliability for continuous measurements. Sample formulas have been derived for explicitly incorporation of a prespecified probability of achieving the prespecified precision, i.e., the width or lower limit of a confidence interval for ICC. Although the concept of ICC is ...

E-Cigarettes: An Up To Date Review And Discussion Of The Controversy, Zachary Sanford, Lynne J. Goebel Md

Lynne J. Goebel

Electronic cigarettes (e-cigarettes) present a novel method for nicotine delivery that is reportedly advantageous when compared to traditional cigarette usage. Manufacturers and consumers claim reduced chemical exposure, decreased symptom profiles, and efficacy in smoking reduction and cessation greater than conventional nicotine replacement therapies (NRT). However these products present new challenges and concerns to legislators, clinicians, and public health advocates. Questions of authority in state and federal legislation, establishing product quality control, assessing long-term studies on e-cigarettes and quantifying usefulness in harm reduction represent only a portion of the many unanswered topics being discussed. The purpose of this article is to ...

Biodegradable Magnesium Alloys For Orthopaedic Applications: A Review On Corrosion, Biocompatibility And Surface Modifications., Sankalp Agarwal, James Curtin, Brendan Duffy, Swarna Jaiswal

Articles

Magnesium (Mg) and its alloys have been extensively explored as potential biodegradable implant materials for orthopaedic applications (e.g. Fracture fixation). However, the rapid corrosion of Mg based alloys in physiological conditions has delayed their introduction for therapeutic applications to date. The present review focuses on corrosion, biocompatibility and surface modifications of biodegradable Mg alloys for orthopaedic applications. Initially, the corrosion behaviour of Mg alloys and the effect of alloying elements on corrosion and biocompatibility is discussed. Furthermore, the influence of polymeric deposit coatings, namely sol-gel, synthetic aliphatic polyesters and natural polymers on corrosion and biological performance of Mg and ...

Currently, there is increasing interest in the in vivo protective effects of natural antioxidants found in dietary plants against oxidative damage caused by free radical species. Oxidative stress has been invoked as a causative agent in cancer and epidemiological data suggest that the consumption of fruits and vegetables may be associated with a lower incidence of cancer. The fruit of the Olea europaea L. and olive oil contain hundreds of phytochemicals and its extracts have recently been shown to exhibit antioxidant properties, due to the action of oleuropein. In view of these considerations, in this study, we investigated the effects ...

Expression Of Heme Oxygenase-1 In Thick Ascending Loop Of Henle Attenuates Angiotensin Ii-Dependent Hypertension, David E. Stec, Heather A. Drummond, Moneete U. Gousette, Megan V. Storm, Nader G. Abraham, Eva Csongradi

Nader G. Abraham

Kidney-specific induction of heme oxygenase-1 (HO-1) attenuates the development of angiotensin II (Ang II) -dependent hypertension, but the relative contribution of vascular versus tubular induction of HO-1 is unknown. To determine the specific contribution of thick ascending loop of Henle (TALH) -derived HO-1, we generated a transgenic mouse in which the uromodulin promoter controlled expression of human HO-1. Quantitative RT-PCR and confocal microscopy confirmed successful localization of the HO-1 transgene to TALH tubule segments. Medullary HO activity, but not cortical HO activity, was significantly higher in transgenic mice than control mice. Enhanced TALH HO-1 attenuated the hypertension induced by Ang ...

Diabetes is a major health problem associated with adverse cardiovascular outcomes. The apolipoprotein A-I mimetic peptide L-4F is a putative anti-diabetic drug, has antioxidant and anti-inflammatory proprieties and improves endothelial function. In obese mice L-4F increases adiponectin levels, improving insulin sensitivity and reducing visceral adiposity. We hypothesized that the pleiotropic actions of L-4F can prevent heart and coronary dysfunction in a mouse model of genetically induced Type II diabetes. We treated db/db mice with either L-4F or vehicle for 8 weeks. Trans-thoracic echocardiography was performed; thereafter, isolated hearts were subjected to ischemia/reperfusion (IR). Glucose, insulin, adiponectin, and pro-inflammatory ...

Background: Prediabetes (PreDM) in asymptomatic adults is associated with abnormal circadian blood pressure variability (abnormal CBPV).

Hypothesis: Systemic inflammation and glycemia influence circadian blood pressure variability.

Methods: Dahl salt-sensitive (S) rats (n = 19) after weaning were fed either an American (AD) or a standard (SD) diet. The AD (high-glycemic-index, high-fat) simulated customary human diet, provided daily overabundant calories which over time lead to body weight gain. The SD (low-glycemic-index, low-fat) mirrored desirable balanced human diet for maintaining body weight. Body weight and serum concentrations for fasting glucose (FG), adipokines (leptin and adiponectin), and proinflammatory cytokines [monocyte chemoattractant protein-1 (MCP-1) and ...


The Relationship Between Qualitative And Quantitative Pain Descriptors Of Prolonged Standing Induced Low Back Pain, Laura Abbott 2016 University of Arkansas, Fayetteville

The Relationship Between Qualitative And Quantitative Pain Descriptors Of Prolonged Standing Induced Low Back Pain, Laura Abbott

Health, Human Performance and Recreation Undergraduate Honors Theses

The purpose of this study was to determine if assessing pain symptoms could help to better define prolonged standing induced low back pain (LBP) development. Thirty-five participants (18 male & 17 female), with no prior history of LBP, preformed two-hours of standing while doing occupational tasks in random 15-minute bouts. The Visual Analogue Scale (VAS) and The Short-Form McGill Pain Questionnaire were used to assess the participant’s current level of LBP in 7.5-minute increments for 120 minutes of standing. Participants were instrumented for motion capture and stood on two force plates to track lumbar spine movement and body weight ...
