We conducted a field study using multiple wearable devices on 231 federal office workers to assess the impact of the indoor environment on individual wellbeing. Past research has established that the workplace environment is closely tied to an individual's wellbeing. Since sound is the most-reported environmental factor causing stress and discomfort, we focus on quantifying its association with physiological wellbeing. Physiological wellbeing is represented as a latent variable in an empirical Bayes model with heart rate variability measures-SDNN and normalized-HF as the observed outcomes and with exogenous factors including sound level as inputs. We find that an individual's physiological wellbeing …
Role Of Vitamin D, Folate, And Cobalamin Deficiency In Mycobacterium Avium Paratuberculosis Infection And Inflammation, Joseph Vaccaro
Role Of Vitamin D, Folate, And Cobalamin Deficiency In Mycobacterium Avium Paratuberculosis Infection And Inflammation, Joseph Vaccaro
Electronic Theses and Dissertations, 2020-2023
Vitamin D, folate, and cobalamin (vitamin B12) are crucial micronutrients in human physiology that are necessary for healthy calcium, phosphorus, and single-carbon metabolism. Recent studies have indicated that these vitamins also affect the inflammatory response in ways unrelated to their well-characterized deficiencies. Accordingly, analysis of their effect on chronic inflammatory diseases like Crohn's disease (CD) is warranted. This investigation examines the effects of vitamin deficiency on macrophages and intestinal epithelial cells upon exposure to Mycobacterium avium paratuberculosis (MAP,) a pathogen capable of triggering CD, to model the inflammatory response in clinical CD patients. ELISA analysis of CD patient plasma established …

The More Severe Adverse Effect Of Alcohol In Fc Gamma Receptor Iib Deficient (Fcgrllb-/-) Lupus Mice Than In Wild-Type Due To The More Profound Responses Against Alcohol-Induced Leaky Gut, Phatcharapon Yiengwattananon
Chulalongkorn University Theses and Dissertations (Chula ETD)
Consuming alcoholic beverages is well-known to have a part in causing inflammation and obstructing the function of the digestive system, and it may lead to leaky intestines. However, the relationship between alcohol consumption and Systemic Lupus Erythematosus (SLE) remains a subject of controversy continued. In general, alcohol can promote intestinal bacterial dysbiosis and also result in endotoxin release by Gram-negative bacteria. This stimulates many immune cells to produce inflammatory cytokines in the gut. This study focuses on the inflammatory response effect of FcgRIIb-/- mice upon loss of FcgRIIb receptors in which alcohol-induced leaky gut can occur. In 8-week-old mice lacking …

CMC Senior Theses
Aging is considered the main risk factor for various neurodegenerative disorders including Alzheimer’s disease (AD) and Parkinson’s disease (PD). Aging is associated with an increase in neuroinflammation, which is a significant contributor to cognitive impairment observed in these age-related neurodegenerative diseases. However, studying brain behavior remains a challenge due to the complex nature of isolating brain tissue from an organism. Modeling the brain allows for further study of these neurodegenerative diseases. Organ-on-a- chip (OoC), a system containing engineered or natural tissues grown within microfluidic chips, has emerged as a promising tool for mimicking human physiology in a controlled microenvironment. A …

Alzheimer’S Disease Genetics And Short-Chain Fatty Acid Treatment In Studies Of The Murine Gut Microbiome, Diana Zajac
Theses and Dissertations--Physiology
Elucidating the relationship of the gut microbiome in Alzheimer's Disease (AD) risk and pathogenesis is an area of intense interest. Since 60 to 80% of AD risk is related to genetics and APOE alleles represent the most impactful genetic risk factors for AD, their mechanism(s) of action are under intense scrutiny.
First, I conducted a study on APOE targeted replacement mice to investigate the impact of APOE alleles on the murine gut microbiome. The relative abundance of bacteria from the family Ruminococacceae and related genera increased with APOE2 status. The relative abundance of the class Erysipelotrichia increased with APOE4 status, …

Characterizing Cellular Injury And Inflammation With Aldob-/-Mouse Model Of Mafld, Andy Rashid
All Master's Theses
Metabolic-associated fatty liver disease (MAFLD) affects 1 in 3 people in the US and is a healthcare burden on the order of billions of dollars. MAFLD is characterized by pathological lipid accumulation in the liver, excess production of triglycerides and cholesterol, and export of LDL particles that raise serum lipid levels. These metabolic perturbations can lead to the development of liver fibrosis, chronic inflammation, and insulin resistance. Diagnosing MAFLD prior to fibrosis is crucial for successful intervention and prevention of advanced liver disease and other metabolic complications. Fructose-1Phospahte (F1P) accumulation from fructose overconsumption can drive hepatic lipogenesis and MAFLD progression. …

Voice Quality Assessment In Cases Of Vocal Fold Gaps After Single Growth Factor Injection, Amr Roushdyel Badrawy, Asmaa Abdel Hamid, Israa Eltaweel, Azza Abdel Aziz Azzam
Journal of Medicine in Scientific Research
In severe vocal fold (VF) lesions, deposits of disorganized, thick collagen bundles and little hyaluronic acid (HA) are deposited in the superficial layer of lamina propria (SLP). These changes lead to severe dysphonia and aspiration, which could be complicated by fatal pneumonia. Unfortunately, no specific treatment has been recognized due to unpredictable VF regeneration. Current progress in regenerative medicine has allowed the development of tissue engineering techniques using cells, scaffolds, and growth factors (GFs). Extrinsic GFs application could help in the induction of the regenerative process. The work aims to assess the voice quality after a single GF injection of …
Exploring The Perceptions Of Genetics, Genetics Testing, And Science In People Of African Descent, Maame-Owusua Boateng
Exploring The Perceptions Of Genetics, Genetics Testing, And Science In People Of African Descent, Maame-Owusua Boateng
Public Health Theses
Background: Historical injustices towards Black populations in the United States have impacted how communities interact with medicine and public health such as medical experimentations, scientific racism, medical racism, and eugenics. Black communities are underrepresented in human genomics projects compared to those that identify as white or of European ancestry. Prior research has demonstrated that Black people are less likely to know about the availability of genetic testing for diseases and have less confidence in the benefits of genetic testing. These disparities make it imperative to understand the perspectives of people of African descent. Methods: The Black Genome Project is an …
Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne
Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne
UNF Graduate Theses and Dissertations
BACKGROUND: Prescription medication use and extended sedentary time are independently related to poor health outcomes (e.g., diabetes, metabolic syndrome, mortality). Historically, survey methods have been used to obtain estimates of total sedentary time (ST), however, recent use of accelerometers avoids self-report bias and affords more characteristics of ST that may be factors in health outcomes (e.g., frequency and duration of sedentary bouts). The aims of this pilot study were to 1) examine the association between objectively measured ST via accelerometers and self-reported prescription medication use in adults and 2) examine the independent association of sedentary bout length and frequency with …

The Influence Of A Low Glycemic Load Diet On Appetite In Women With Pcos, Sarah Et Hoover
All ETDs from UAB
Dysregulated appetite may contribute to weight gain and high prevalence of comorbid obesity in women with polycystic ovary syndrome (PCOS), yet dietary recommendations to promote satiety and facilitate weight maintenance in this population remain scarce. The objective of this dissertation was to determine if women with PCOS have alterations in appetite-regulating hormones that can be manipulated by low glycemic load diet habituation to improve satiety. This was tested by secondary analyses of two randomized controlled dietary intervention trials in women with and without PCOS. First, we explored differences in women with and without PCOS during a standardized liquid meal test …
Investigating The Electrostatics Of Mucins As Key Contributors To Mucus Stasis In Cystic Fibrosis, Elex Skylar Rose
Investigating The Electrostatics Of Mucins As Key Contributors To Mucus Stasis In Cystic Fibrosis, Elex Skylar Rose
All ETDs from UAB
Cystic fibrosis (CF) is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which encodes a channel responsible for the transport of chloride and bicarbonate ions across the apical cell surface. In the respiratory tract, defective CFTR results in viscous and adherent mucus that becomes static within the airway, which leads to chronic infections, progressive lung damage, and early mortality. Historically, CF mucus stasis has been attributed to significant airway dehydration; however, growing evidence has demonstrated that aberrant electrostatic properties of mucins also contribute to mucus stasis in CF. Mucins are large, polymeric glycoproteins …

Influence Of Female Sex Hormones On Ghb Toxicokinetics And Regulation Of Mcts And Smcts, Hao Wei
University of the Pacific Theses and Dissertations
Gamma-hydroxybutyric acid (GHB) is an endogenous shorty chain fatty acid that is used clinically as Xyrem to treat narcolepsy. GHB is best known for its illicit use and abuse due to its sedative/hypnotic and euphoric effects. It is used in body building, for recreational use and sexual assault. Nonlinear toxicokinetics of GHB has been described in humans and rats with decreased total clearance at higher doses due to capacity-limited metabolism resulting in a higher plasma exposure. Renal clearance increases with increasing dose and becomes the major route of GHB elimination in overdose cases due to saturation of GHB metabolism. Proton- …

INTRODUCTION: Mesenchymal Stromal/Stem cells (MSCs) are an essential component of the regenerative and immunoregulatory stem cell compartment of the human body and thus of major importance in human physiology. The MSCs elicit their beneficial properties through a multitude of complementary mechanisms, which makes it challenging to assess their phenotype and function in environmental toxicity screening. We here employed the novel combinatorial assays matrix approach/technology to profile the MSC response to the herbicide Atrazine, which is a common environmental xenobiotic, that is in widespread agricultural use in the US and other countries, but banned in the EU. Our here presented approach …

Neurotransmitters (NTs) play a crucial role in regulating the behavioral and physiological functions of the nervous system. Imbalances in the concentrations of NT have been directly linked to various neurological diseases (e.g., Parkinson’s, Huntington’s, and Alzheimer’s disease), in addition to multiple psychotic disorders such as schizophrenia, depression, dementia, and other neurodegenerative disorders. Hence, the rapid and real-time monitoring of the NTs is of utmost importance in comprehending neurological functions and identifying disorders. Among different sensing techniques, electrochemical biosensors have garnered significant interest due to their ability to deliver fast results, compatibility for miniaturization and portability, high sensitivity, and good controllability. …
Reliability And Validity Of A Commercial Running Power Meter To Indicate Metabolic Workload During Endurance Running, James Harris Hudgins Iii
Reliability And Validity Of A Commercial Running Power Meter To Indicate Metabolic Workload During Endurance Running, James Harris Hudgins Iii
Theses and Dissertations--Kinesiology and Health Promotion
Commercial running power (RP) meters may provide endurance runners and coaches with improved precision for monitoring running intensity. Cyclists rely upon the relationship between cycling power and metabolic demand to regulate physiological intensity during training and racing, independent of changes in the physical environment (e.g., terrain, wind). Research demonstrates strong reliability and validity for a specific RP meter to indicate metabolic demand within controlled running conditions. However, several potential influences on this relationship have not been investigated. Therefore, four studies were conducted with the following aims:
- Study 1: Determine the inter-limb reliability and validity of a single-limb-based RP meter …
An Examination Of Kinanthropometric And Physical Injury Risk Factors In Elite Australian Football, Callum J. Mccaskie
An Examination Of Kinanthropometric And Physical Injury Risk Factors In Elite Australian Football, Callum J. Mccaskie
Theses: Doctorates and Masters
Kinanthropometric assessment is an integral part of understanding an athlete’s physical profile and readiness for competition. This typically includes a variety of different assessments which serve to quantify body shape, proportion, and composition in a bid to understand human physiology. Common assessments include stature, body mass, limb ratios, body circumferences, body mass index, skinfold testing, body composition testing, and musculoskeletal morphological evaluations. Specifically, kinanthropometric evaluations have involved the characterisation of athletes according to sport, sex, competition level and playing position. While this has provided researchers and practitioners with greater insight into athletic phenotypes, more purposeful kinanthropometric assessments which focus on …

Reduced Serum Concentrations Of Reactive Oxygen And Nitrogen Species Following Strenuous Exercise In The Heat Are Not Associ-Ated With An Upregulation In Serum Antioxidative Capacity, Sebastian Keller, Hannah Lisa Notbohm, Wilhelm Bloch, Moritz Schumann
Baltic Journal of Health and Physical Activity
Introduction: Reactive oxygen and nitrogen species (RONS) are produced as a response to exercise and play a part in guiding the adaptive response to physical training. Exercise in the heat has been shown to further increase accumulation of RONS in systemic circulation; however, a high antioxidative response or heat acclimatization mechanisms could attenuate this response. In a previous study, we found reduced RONS concentrations in trained athletes following strenuous cycling in the heat. Therefore, this secondary analysis assessed whether these reduced RONS serum concentrations are induced by an increased serum antioxidant capacity. Methods: Twelve male cyclists (V̇O2peak: 60 …

Apnea ability is the main determining factor of freediving performance. Apnea relates to physiological factors that might be experienced by a free diver hence its ability is highly likely to correlate with various factors of human physiology. One of the suspected factors that affect apnea duration is body fat level. The fact that fat is distributed in almost all parts of the body, including respiratory organs and tracts, arises the suspicion of a possible correlation between fat accumulation and apnea ability. This research studies the correlation between body fat level and apnea duration. 30 males, aged 18-22 were the research …

On Kernel-Based Estimator Of Odds Ratio Using Different Stratified Sampling Schemes, Abbas Eftekharian, Hani Samawi, Haresh Rochani
Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications
The kernel-based estimator of Cochran Mantel-Haenszel odds ratio based on stratified simple and ranked set sampling is proposed. The expectation and variance of the estimator are analytically obtained. Using a simulation study, the estimator based on stratified ranked set sampling is more efficient than its counterpart based on stratified simple random sampling. Finally, the estimator's performance is investigated by using base deficit data.

Knowledge transfer among research disciplines can lead to substantial research progress. At first glance, astronaut health and rare diseases may be seen as having little common ground for such an exchange. However, deleterious health conditions linked to human space exploration may well be considered as a narrow sub-category of rare diseases. Here, we compare and contrast research and healthcare in the contexts of rare diseases and space health and identify common barriers and avenues of improvement. The prevalent genetic basis of most rare disorders contrasts sharply with the occupational considerations required to sustain human health in space. Nevertheless small sample …

Human circadian, neuroendocrine, and neurobehavioral responses to light are mediated primarily by melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs) but they also receive input from visual photoreceptors. Relative photoreceptor contributions are irradiance- and duration-dependent but results for long-duration light exposures are limited. We constructed irradiance-response curves and action spectra for melatonin suppression and circadian resetting responses in participants exposed to 6.5-h monochromatic 420, 460, 480, 507, 555, or 620 nm light exposures initiated near the onset of nocturnal melatonin secretion. Melatonin suppression and phase resetting action spectra were best fit by a single-opsin template with lambdamax at 481 and 483 …

He entered treatment before adjudication and was mandated by the court to continue treatment to assist in maintaining sobriety. Treatment included the administration of the Genetic Addiction Risk Severity (“GARS”) Test.
AG was facing a probable five-year sentence for his fifth DWI conviction in Bexar County, Texas. However, because AG’s genetic risk results indicated a genetically induced dopamine dysfunction, hypodopaminergia, …
Nursing Considerations For Post-Traumatic Amnesia After A Traumatic Brain Injury, Hannah Grant
Nursing Considerations For Post-Traumatic Amnesia After A Traumatic Brain Injury, Hannah Grant
Senior Honors Theses
A period known as post-traumatic amnesia (PTA) often follows a traumatic brain injury (TBI). PTA is characterized by anterograde and retrograde amnesia, confusion, disorientation, and agitation. The duration and severity of PTA is a key indicator of the long-term prognosis after a TBI, so proper assessment and nursing care of a PTA patient is crucial. TBIs range from mild to severe, but primarily affect the fronto-temporal lobes. In PTA, both neural lesions and white matter damage within the parahippocampal region can cause PTA. A nurse must perform a thorough assessment of a TBI patient, but, since PTA is a key …

Worried Sick: Understanding The Implications Of Stress On A Physiological Level, Julia Saia
Senior Honors Theses
Stress is prevalent among many individuals in today’s society. A literature review was conducted to investigate the physiological effects of stress, including the biomarkers of stress and how these interact with various body systems. The stress response is a protective mechanism to prepare the body to adequately respond to a perceived threat. However, when this response is prolonged, it begins to have a maladaptive effect on the body and can cause more harm than good. This literature review sought to compile what is known regarding the general effects of chronic stress and its impact on the nervous, immune, digestive, and …

We integrated lipidomics and genomics to unravel the genetic architecture of lipid metabolism and identify genetic variants associated with lipid species putatively in the mechanistic pathway for coronary artery disease (CAD). We quantified 596 lipid species in serum from 4,492 individuals from the Busselton Health Study. The discovery GWAS identified 3,361 independent lipid-loci associations, involving 667 genomic regions (479 previously unreported), with validation in two independent cohorts. A meta-analysis revealed an additional 70 independent genomic regions associated with lipid species. We identified 134 lipid endophenotypes for CAD associated with 186 genomic loci. Associations between independent lipid-loci with coronary atherosclerosis were …

Chronic ethanol consumption contributes to the global prevalence’s of cardiovascular disease by mechanisms involving an inflammatory response and consequent lipid peroxidation. Cytochrome p450 is a part of the microsomal ethanol oxidizing system (MEOS) and can utilize iron complexes and the reductant NADPH to catalyze the breakdown of acute/chronic ethanol consumption. However, efficacy of MEOS to prevent cardiovascular burden induced by ethanol consumption is not clear. PURPOSE: To demonstrate the response of the cardiovascular system in response to the oxidative metabolic breakdown of ethanol via MEOS. METHODS: An extensive literature search provided data to develop a mechanistic model of the metabolism …
