Evaluation Of Heat Stress In Migrant Farmworkers, Stephen L. Mcqueen
Evaluation Of Heat Stress In Migrant Farmworkers, Stephen L. Mcqueen
Electronic Theses and Dissertations
The rate of heat-related fatalities in crop production workers is almost 20 times that of other industries. Heat stress was investigated in migrant tomato workers in July, 2012, using measurements of body temperature, heart rates, body weight loss, evaluation of the thermal environment, and survey data. Using occupational safety criteria, these workers were found to work in an environment that should require protective measures to prevent heat strain. Increases in body temperature, heart rate, and physiological strain correlated with heat exposure. One third of workers had body weight percentage losses that indicated dehydration. However, working in hot environments appears to …
Expectations And Experiences Of Fathers Who Have Parented Children With And Without Intellectual Disabilities, Jane Christina Kusmik Walker
Expectations And Experiences Of Fathers Who Have Parented Children With And Without Intellectual Disabilities, Jane Christina Kusmik Walker
Electronic Theses and Dissertations
The parenting experience is as diverse as the children parented. Each child has diverse personality traits requiring flexibility and specificity in parenting strategy. This need for flexibility and specificity is more complex when one or more children within a family has an intellectual disability. Although research in this area is abundant, investigators have historically focused on mothers' attitudes, beliefs, and behaviors to represent the entire family (Essex, Seltzer, & Krauss, 2001; Greenberg, 2002) rather than focusing on fathers and their caregiving relationships with their children in need of malleable but consistent parenting. Using a qualitative descriptive design, this qualitative study …

Il-1Β Amplification Of Nitric Oxide Production And Its Inhibitory Effects On Glucose Induced Early Growth Response-1 Expression In Ins-1 Cells, Ada Young
Electronic Theses and Dissertations
The pathophysiology of cytokines released by infiltrating white blood cells upon pancreatic beta cells is not fully understood. Early growth response gene-1 (Egr-1) expression is specifically and transiently up regulated in pancreatic beta cells in response to glucose. We hypothesized that interleukin-1 beta (IL-1▀) induction of nitric oxide alters glucose induced Egr-1 transcription levels. Egr-1 levels were assessed via western blot, nitric oxide was measured with a Griess Reagent kit and insulin levels via ELISA. Glucose induced both insulin and Egr-1 production in INS-1 cells. IL-1▀ dose dependently increased nitric oxide production over time and significantly attenuated glucose induced Egr-1 …

Rapid Detection Of Streptococcus Mutans In Saliva, Catherine E. Holtman
Electronic Theses and Dissertations
Documentation exists that mothers can pass the cariogenic bacteria Streptococcus mutans to their infants. The newest technology to identify Streptococcus mutans is a rapid detection saliva test. Two hundred patients above the age of 18 were targeted using random selection in a Louisville, Kentucky dental office. Patients signed an informed consent form and were given a qualifying questionnaire. Patients received 2 bitewing x-rays and a charted DMFT index and were administered the saliva test. While the null hypothesis was rejected using the chi square test, the results were inconclusive due to expected values. However, other chi square results revealed that …
Advancing Global Tobacco Control: Exploring Worldwide Youth Attitudes And Behaviors Toward Tobacco Use And Control, Sreenivas Phanikumar Veeranki
Advancing Global Tobacco Control: Exploring Worldwide Youth Attitudes And Behaviors Toward Tobacco Use And Control, Sreenivas Phanikumar Veeranki
Electronic Theses and Dissertations
Tobacco use continues to be the leading cause of preventable death in the world. The disproportionate increase in tobacco use in low- and middle-income countries needs immediate attention. Many smokers begin smoking as adolescents and are most likely to become permanent smokers. Moreover, youth are highly targeted by tobacco industry strategies. However, a gap exists in literature to understand worldwide youth tobacco use and control. The purpose of this study is to 1) identify factors that influence never-smoking youths‟ smoking susceptibility, 2) explore characteristics that influence youth exposure to environmental tobacco smoke (ETS) and 3) to delineate key determinants of …
Effects Of Burn Injury On Biological Ethanol And Ethyl Glucuronide Concentrations, Trista Haupt Wright
Effects Of Burn Injury On Biological Ethanol And Ethyl Glucuronide Concentrations, Trista Haupt Wright
Electronic Theses and Dissertations
Alcohol is the most abused drug in the United States and most frequently performed assay in forensic laboratories. Alcohol is routinely present in biological specimens from fatal residential fires and forensic toxicologists must interpret if these individuals are impaired by determination of their blood alcohol concentrations on post-incineration blood collected at autopsy. There is no known data available to confirm or refute blood alcohol concentrations and impairment in fire-related deaths. Ethyl glucuronide (EtG), a non-volatile minor ethanol metabolite, may provide a better biomarker for ethanol consumption prior to burn injury. The literature does not address the possibility that ethanol or …
The Effects Of Nicotine Administration On Behavior And Markers Of Brain Plasticity In A Rodent Model Of Psychosis, Marla K. Perna
The Effects Of Nicotine Administration On Behavior And Markers Of Brain Plasticity In A Rodent Model Of Psychosis, Marla K. Perna
Electronic Theses and Dissertations
Schizophrenia affects about 1% of the population. A hallmark of the disorder is increased dopamine D2 receptor sensitivity in the brain. Studies have shown that schizophrenics smoke cigarettes at approximately 4 times the rate of the general population. It has been suggested that nicotine use is a form of self-medication for symptoms in schizophrenia. Smoking behaviors typically begin in adolescence. We assessed effects of nicotine on behavior and brain plasticity in an adolescent rodent model of schizophrenia with the goal of identifying targets for smoking cessation. Methods: Rats were neonatally treated with quinpirole (a D2/D3 agonist) or saline and sensitized …

The constant evolution of medical technology has increased the demand for managing medical devices to ensure safety and effectiveness. In this paper I will investigate how biomedical engineering has addressed the issue of equipment management and identifies strategies to successfully maintain an inventory of medical devices. Through research, on-the-job experience, and in-depth discussions with various biomedical engineering managers, I have been able to document possible equipment strategies and best practices for managing medical devices. There is really no "one size fits all" to medical equipment management due to the various clinical environments, but there are many aspects that remain necessary …
A Consensus Model For Electroencephalogram Data Via The S-Transform, Andrew Coady Young
A Consensus Model For Electroencephalogram Data Via The S-Transform, Andrew Coady Young
Electronic Theses and Dissertations
A consensus model combines statistical methods with signal processing to create a better picture of the family of related signals. In this thesis, we will consider 32 signals produced by a single electroencephalogram (EEG) recording session. The consensus model will be produced by using the S-Transform of the individual signals and then normalized to unit energy. A bootstrapping process is used to produce a consensus spectrum. This leads to the consensus model via the inverse S-Transform of the consensus spectrum. The method will be applied to both a control and experimental EEG to show how the results can be used …
Exploring The Unique Characteristics Of Cancer In Adolescents And Young Adults In Tennessee, Megan Quinn
Exploring The Unique Characteristics Of Cancer In Adolescents And Young Adults In Tennessee, Megan Quinn
Electronic Theses and Dissertations
Adolescents and Young Adults (AYAs) ages 15-39 years with cancer have received little attention in the medical and health fields, resulting in a lack of progress for this age group. Little is known about the unique biologic, epidemiologic, and psychosocial issues that play an integral role in the AYA cancer journey. The purposes of this study were to use the Tennessee Cancer Registry for all new cancer cases from 2004-2008 to determine 1) the main types of cancer that affect AYAs in TN, 2) the predictors of late-stage diagnosis of melanoma, and 3) the factors that predict a total thyroidectomy …

A Measurement Of Readiness For Tennessee Hospitals To Implement “Meaningful Use” Criteria Resulting From The American Recovery And Reinvestment Act, 2009, Kathryn Wallin Wilhoit
Electronic Theses and Dissertations
In 2009, the American Recovery and Reinvestment Act was signed into law. This legislation provided for monetary rewards for those acute-care hospitals that meet "meaningful use" computerization and reporting criteria.
The study used a descriptive, nonexperimental design to answer three research questions (1) What is the level of readiness to meet "meaningful use" criteria in the Tennessee Hospital Association (THA) member hospitals; (2) What is the level of readiness to meet "meaningful use" criteria in the rural THA member hospitals; and (3) Is there a difference in the readiness to meet "meaningful use" criteria between rural and urban THA member …
Prelamin A Influences A Program Of Gene Expression In Regulation Of Cell Cycle Control, Christina N. Bridges
Prelamin A Influences A Program Of Gene Expression In Regulation Of Cell Cycle Control, Christina N. Bridges
Electronic Theses and Dissertations
The A-type lamins are intermediate filament proteins that constitute a major part of the eukaryotic nuclear lamina—a tough, polymerized, mesh lining of the inner nuclear membrane, providing shape and structural integrity to the nucleus. Lamin A (LA) filaments also permeate the nucleoplasm, providing additional structural support, but also scaffolding numerous tethered molecules to stabilize, organize, and facilitate molecular interactions to accomplish critical functions of cellular metabolism. Over the past 2 decades, much attention has been focused on roles of LA in maintenance of nuclear structural integrity. Only since the late 1990s have scientists discovered the devastating effects of LA gene …
Stabilization Of The Cardiac Nervous System During Cardiac Stress Induces Cardioprotection, David D. Gibbons
Stabilization Of The Cardiac Nervous System During Cardiac Stress Induces Cardioprotection, David D. Gibbons
Electronic Theses and Dissertations
The cardiac nervous system consists of nested reflex feedback loops that interact to regulate regional heart function. Cardiac disease affects multiple components of the cardiac nervous system and the myocytes themselves. This study aims to determine: 1) how select components of the cardiac nervous system respond to acute cardiac stress, including myocardial ischemia (MI) and induced neural imbalance leading to cardiac electrical instability, and 2) how neuromodulation can affect neural-myocyte interactions to induce cardioprotection. Thoracic spinal cord stimulation (SCS) is recognized for its anti-anginal effects and ability to reduce apoptosis in response to acute MI, primarily via modulation of adrenergic …
