Social Determinants Of Health And Blood Pressure Control In Black And White Us Adults, Oluwasegun Philip Akinyelure Jan 2023

Social Determinants Of Health And Blood Pressure Control In Black And White Us Adults, Oluwasegun Philip Akinyelure

All ETDs from UAB

Black adults in the US have 2 to 3 times higher rates of cardiovascular disease (CVD) mortality compared to White adults. Most of the excess CVD mortality in Black adults has been attributed to their higher prevalence of hypertension and uncontrolled blood pressure (BP). In October 2020, the US Surgeon General published a Call-to-Action to improve hypertension control and identified social determinants of health (SDOH) as a major contributor to Black:White disparities in hypertension control. Prior research has showed that SDOH are associated with excess hypertension risk among Black compared with White adults, but data on their association with BP …


Longitudinal Effects Of Adolescent Digital Media Use On Sleep, Cardiometabolic Health, And Mental Health, Caroline Watson Jan 2023

Longitudinal Effects Of Adolescent Digital Media Use On Sleep, Cardiometabolic Health, And Mental Health, Caroline Watson

All ETDs from UAB

Background Digital media use has become an integral part of society and may contribute to adverse physical and mental health outcomes, particularly among adolescents. However, few studies have examined the longitudinal effects of adolescent digital media use across the transition from adolescence to young adulthood. As adolescents present as a highrisk group for the adverse effects of digital media use on mental and physical health, the present studies identified digital media use trajectories from adolescence into young adulthood and examined these trajectories as predictors of sleep duration, cardiometabolic health, and mental health outcomes in young adulthood. Methods Participants (Mage=15.53; 56.86% …


Interactions Between Pseudomonas Aeruginosa And The Oral Commensal Streptococcus Salivarius, Sara Noelle Stoner Jan 2023

Interactions Between Pseudomonas Aeruginosa And The Oral Commensal Streptococcus Salivarius, Sara Noelle Stoner

All ETDs from UAB

The cystic fibrosis airway is a polymicrobial environment often dominated by opportunistic pathogens such as Pseudomonas aeruginosa, a leading cause of lung function decline and mortality in persons with CF. Commensal streptococcal colonization has been associated with stable CF lung function in multiple studies. However, few studies have examined interactions between P. aeruginosa and commensals as well as their impact on P. aeruginosa airway infections. In the first half of this work, we studied interactions between P. aeruginosa and the oral commensal Streptococcus salivarius within a biofilm setting. We found that S. salivarius biofilm formation is promoted by the non-mucoid …


Intent-To-Treat Versus Per Protocol Analysis Of A Crossover Feeding Trial: Effect Of Dietary Sodium On Obstructive Sleep Apnea, Gabrielle Gloston Jan 2023

Intent-To-Treat Versus Per Protocol Analysis Of A Crossover Feeding Trial: Effect Of Dietary Sodium On Obstructive Sleep Apnea, Gabrielle Gloston

All ETDs from UAB

Obstructive sleep apnea (OSA) is a common form of sleep disordered breathing that leads to poor daytime functioning. It is strongly associated with hypertension (HTN) and apneic events in individuals with OSA can drive blood pressure (BP) surges at night. Treating OSA with continuous positive airway pressure (CPAP) has led to reductions in day- and nighttime BP and treatment of HTN has also been reported to have beneficial effects on OSA severity. Dietary sodium has long been implicated in HTN and dietary sodium restriction improves BP levels. Recently, dietary sodium restriction was found to reduce OSA severity in men with …


Physical Activity Promotion In Persons Newly Diagnosed With Multiple Sclerosis, Le Thao Trinh Huynh Jan 2023

Physical Activity Promotion In Persons Newly Diagnosed With Multiple Sclerosis, Le Thao Trinh Huynh

All ETDs from UAB

Multiple sclerosis (MS) is a prevalent immune-mediated, neurodegenerative disorder, affecting approximately 1 million people in the United States. MS onset is commonly between 20 and 40 years of age, and persons with MS often live a long life with the disease resulting from the early initiation of disease-modifying therapies and comorbidity-managing approaches. Notably, physical activity is promising for disease modification and symptoms and comorbidity management in MS. Yet, physical activity has been initiated quite late during the disease course. Further, early MS could be a “window of opportunity” for initiating physical activity to maximize its health benefits for symptom management …


Streptococcus Mutans Biofilm Inhibiting Small Molecules With Anticariogenic Activity, Parmanand Ahirwar Jan 2023

Streptococcus Mutans Biofilm Inhibiting Small Molecules With Anticariogenic Activity, Parmanand Ahirwar

All ETDs from UAB

Dental caries, a highly prevalent disease, is characterized by the erosion of the tooth surface. This disease is caused by the oral bacteria living in complex communities called biofilms. Streptococcus mutans, among the various pathogenic bacterial species inhabiting the oral cavity, is considered to be the major etiological agent for dental caries. This bacterium forms robust biofilms capable of producing significant amounts of acid, leading to the demineralization of hydroxyapatite in the tooth enamel and subsequent erosion over time. Biofilm penetration into the dentin and pulp causes severe pain, while the entry of the bacteria into the bloodstream can result …


Acute Placental Inflammation And Growth Outcomes In Preterm Infants, Emily Gunawan Jan 2023

Acute Placental Inflammation And Growth Outcomes In Preterm Infants, Emily Gunawan

All ETDs from UAB

Background. Acute placental inflammation (API) has been associated with various adverse outcomes in preterm infants. However, little is known about how API affects their body composition and growth outcomes. This study aims to examine the association between API and growth outcomes in preterm infants. Methods. We conducted a retrospective cohort study of mother-infant dyads born < 326/7 weeks of gestation with fat mass (FM) accretion measured using air displacement plethysmography at term-equivalent age. API severity including maternal inflammatory response (MIR) and fetal inflammatory response (FIR) was staged according to criteria by Society for Pediatric Pathology based on placental pathology reports. We examined the differences in characteristics of mother-infant dyads by API severity using ANOVA or the Kruskall-Wallis test. The association between API severity and growth outcomes was analyzed using linear regression models and adjusted for statistically significant confounders. Mediation analyses were used to study the direct and indirect association of API and growth outcomes via gestational age. Results. Among 375 mother-infant dyads analyzed, 104 (28%) dyads had MIR. FIR was found in 82% of dyads with MIR. Adjusted models indicated that API severity progression was positively associated with FM accretion. Gestational age partially (49%) iv mediated the association between API severity and FM z score (indirect effect: b=0.12, 95% CI: 0.05-0.19; direct effect: b=0.12, 95% CI: 0.01-0.25). Conclusions. API severity is associated with growth outcomes and helps to accurately predict body composition in preterm infants.


Early Life Stress And Endothelin Receptor Type A: Separate Roles In Mediating Colitis, Rachel Q. Muir Jan 2023

Early Life Stress And Endothelin Receptor Type A: Separate Roles In Mediating Colitis, Rachel Q. Muir

All ETDs from UAB

Inflammatory bowel disease (IBD) results from the interplay of genetic susceptibility, environmental influences, the microbiota, and aberrant immune responses. Despite the fact that over 200 genetic susceptibility loci have been identified, the genetic contribution to disease onset is believed to be less than 50%. Environmental factors have arisen as key drivers of disease. Early life stress (ELS) is an understudied environmental trigger linked to IBD susceptibility. Utilizing 2 separate models of ELS, we show that ELS results in diminished colonic corticosterone and prolonged intestinal inflammation upon colitogenic insult. ELS-exposed animals consistently demonstrated high levels of colonic Tnf, concurrently with decreased …


Investigating Regulatory Mechanisms Of Transcription By Rna Polymerase I, Abigail Kate Huffines Jan 2023

Investigating Regulatory Mechanisms Of Transcription By Rna Polymerase I, Abigail Kate Huffines

All ETDs from UAB

There are at least three eukaryotic RNA polymerases (Pols), Pols I, II, and III. These Pols are essential for transcription, where RNA is synthesized from various DNA templates. While transcription has been well-studied for decades, there are still many questions that remain unanswered about how this process is regulated for each of the three Pols. Transcription is highly regulated and complex, therefore, many different mechanisms exist to tightly control it in the cell. Some of these mechanisms include regulation by transcription factors and co-transcriptional RNA processing. While these regulatory mechanisms are of great interest, they have not yet been fully …

The purpose of this research was to evaluate the influence of remote training and food security status on body composition and performance changes during off-season training. Aims 1 and 2 focus specifically on how factors affect body composition changes in collegiate football players during off-season training. Data were collected from routine body composition testing and food security screening …


Induction Of Antibiotic Activity Against Methicillin-Resistant Staphylococcus Aureus In Small Molecules Through Zinc Activation, Rachel Michaela Andrews Jan 2023

Induction Of Antibiotic Activity Against Methicillin-Resistant Staphylococcus Aureus In Small Molecules Through Zinc Activation, Rachel Michaela Andrews

All ETDs from UAB

Methicillin-resistant Staphylococcus aureus (MRSA) is a serious human pathogen with a staggering potential for multi-drug resistance. Because of this, the Centers for Disease Control and Prevention and the World Health Organization monitor the spread of MRSA and encourage antibiotic development efforts targeting this pathogen. Despite this, few antibiotics have been developed and brought to market in recent decades. To continue treating infections caused by this organism, we must identify novel antibiotic molecules with different mechanisms of action from known antibiotics. Bacterial copper-dependent inhibitors (CDIs), molecules that become antibacterial in the presence of copper (Cu), have been studied as a novel …

Blood is a powerful form of evidence that can provide valuable information about a crime. Most commonly blood is a source of DNA, however, generating a DNA profile can be costly, time consuming, and sometimes is not possible. Consequently, it is important to have methods for gathering additional information from blood evidence. Attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy is a method commonly used in confirmatory testing of drugs, fibers, paints, and other substances of forensic interest. This method only requires a small amount of sample, is non-destructive, sample preparation is minimal, and analysis is relatively fast. Recent research …


Family Members' Education And Cognitive Functioning Among Older Adults: Investigating The Mediating Role Of Health Behaviors, Lu Tian Jan 2023

Family Members' Education And Cognitive Functioning Among Older Adults: Investigating The Mediating Role Of Health Behaviors, Lu Tian

All ETDs from UAB

Despite a well-established relationship between education and cognitive performance in later life, few studies have considered the effects of educational attainment of the family. The education of one's parents can help prevent cognitive decline, as parents (G1) with more education can transfer more health knowledge, teach health literacy, and cultivate healthy lifestyles. This downward spillover between parental education (G1) and older adults’ (G2) cognitive health is well documented. For the downstream effect, attention is often given to maternal education rather than paternal education. Another line of research examined intergenerational transmissions from children (G3) to parents (G2), finding that having well-educated …


Weight Loss And Physical Activity For People With Physical Disabilities, Julianne Clina Jan 2023

Weight Loss And Physical Activity For People With Physical Disabilities, Julianne Clina

All ETDs from UAB

People with physical disabilities (PWD) are at higher risk of obesity than people with-out physical disability (PWoD). For PWD, obesity presents a greater risk of secondary conditions; preventable medical, emotional, or social problems resulting directly or in-directly from an initial disabling condition. There is incomplete information about how disability-specific concerns influence obesity treatment and weight management, in part because PWD have typically not been included in this research. Additionally, while studies exist examining weight loss in PWD, a dearth of research exists examining weight loss maintenance for this population. Previously, weight control registries have been a valuable tool in gaining …

With the expansion of the aquaculture industry, sustainable shifts in aquaculture must be made to access nutrients essential to human health in response to a decline in marine resources for aquafeeds. Along with shifts in aquafeed composition, selective breeding programs aid in enhancing production-related traits, like growth and feed efficiency, and disease resistance to improve overall profits. Dietary components are important in relation to the growth and metabolism of fishes. Recent research has focused on the benefits of micronutrient supplementation (e.g., choline, methionine, selenium, etc.) on growth performance in fishes. Rainbow trout are a commercially important aquaculture species in the …

Variation In The Gut Microbiome In Response To Nutrition In Danio Rerio, George Brian Hadley Green

All ETDs from UAB

Like humans, Danio rerio, commonly known as the zebrafish, generally harbor millions of gut microbes, whose commensal microbial organisms aid in digestive physiology, nutrition, and host health. The emergence of high throughput sequencing technology (HTS) enables researchers to sequence collective microbial genomes, providing information on the composition of entire microbial communities, as well as the dynamics across taxa encompassing the overall community. Thus, the advancement of genome sequencing and metagenomic analysis have provided a broader understanding of resident and exogenous microbes across biological model organisms. These technologies have enabled researchers to review a spectrum of endogenous and exogenous factors influencing …


Time-Restricted Feeding Modulates Dgat2 Expression In Cardiac And Skeletal Muscle, Yiming Guo Livelo Jan 2023

Time-Restricted Feeding Modulates Dgat2 Expression In Cardiac And Skeletal Muscle, Yiming Guo Livelo

All ETDs from UAB

Circadian disruption caused by aging, genetic, environmental, and lifestyle factors can lead to compromised cardiac and skeletal muscle function and potentially accelerate the progression of metabolic diseases. Time-restricted feeding/eating (TRF/TRE, referred to as TRF hereafter), a dietary intervention that confines food intake within a consistent window of the day, has pleiotropic benefits from flies and mice to humans. However, the effectiveness of TRF on heart and muscle in the context of various metabolic challenges such as circadian disruption and obesity is largely unknown. Current insights into the mechanisms of TRF are primarily based on multi-omics approaches, particularly transcriptomes; however, limited …
