Increasing Maternal Or Post-Weaning Folic Acid Alters Gene Expression And Moderately Changes Behavior In The Offspring, Subit Barua, Kathryn K. Chadman, Salomon Kuizon, Diego Buenaventura, Nathan W. Stapley, Felicia Ruocco, Umme Begum, Sara R. Guariglia, W. Ted Brown, Mohamad Junaid

Publications and Research

Background: Studies have indicated that altered maternal micronutrients and vitamins influence the development of newborns and altered nutrient exposure throughout the lifetime may have potential health effects and increased susceptibility to chronic diseases. In recent years, folic acid (FA) exposure has significantly increased as a result of mandatory FA fortification and supplementation during pregnancy. Since FA modulates DNA methylation and affects gene expression, we investigated whether the amount of FA ingested during gestation alters gene expression in the newborn cerebral hemisphere, and if the increased exposure to FA during gestation and throughout the lifetime alters behavior in C57BL/6J mice.

Efficacy Of Cleaning Method For Removal Of Exogenous Welding Fume Contamination From Nail Tissue Prior To Use As A Biomarker For Welding Fume Manganese Exposure, Jeffrey Corral Bainter

Open Access Theses

Nail tissue has been proposed as a biomarker for body burden of occupational exposure to manganese from welding fumes. Though recent studies have shown correlation between manganese exposure and both nail tissue concentration as well as concentrations in dopaminergic regions of the brain, concerns of the validity of nail tissue as a biomarker have arisen due to the potential for exogenous contamination of Mn to undermine the quantization of endogenous Mn in nail. Previous studies have used a cleaning method of 1% Triton X-100 surfactant plus sonication in order to attempt to remove exogenous welding fume contamination. Determination of the …

Cancer And Infection, Kathleen Hope Plummer

USF Tampa Graduate Theses and Dissertations

E. coli is the most frequently isolated Gram negative pathogen from bacteremia in cancer patients and is repeatedly recovered from many other extraintestinal illnesses. These infections are commonly endogenous in nature and interfere with the treatment of cancer resulting in increased healthcare costs, morbidity, and mortality rates. Cancer and the treatments related to cancer cause alterations in the microbiome of the gut and other organs. Despite this point, there is a serious lack of knowledge about the genetic types of E. coli infecting cancer patients. This gap results in vague prevention strategies and limited treatment options for cancer patients. Multi …

Investigating The Viability Of Two Stenotrophomonas Maltophilia Isolates After Air-Drying, Samantha Lane, Joanna Brooke

DePaul Discoveries

Abstract

Stenotrophomonas maltophilia is a water-borne infectious bacterium that is found in both clinical (hospitals) and non-clinical environments. This human pathogen is commonly recovered from respiratory tract infections. A recent study at a hospital in Taiwan suggested that dry patient charts can serve as a vehicle of transmission of this bacterium⁷. As S. maltophilia is not commonly isolated from dry surfaces, this current study tested the hypothesis that this pathogen can remain viable for some time on a dry surface. This study was designed to determine how long S. maltophilia could remain viable after air-drying by observing …

Paleoparasitological Studies On Mummies Of The Joseon Dynasty, Korea, Min Seo, Adauto Araújo, Karl J. Reinhard, Jong Yil Chai, Dong Hoon Shin

Karl Reinhard Publications

Paleoparasitology is the application of conventional or molecular investigative techniques to archeological samples in order to reveal parasitic infection patterns among past populations. Although pioneering studies already have reported key paleoparasitological findings around the world, the same sorts of studies had not, until very recently, been conducted in sufficient numbers in Korea. Mummified remains of individuals dating to the Korean Joseon Dynasty actually have proved very meaningful to concerned researchers, owing particularly to their superb preservation status, which makes them ideal subjects for paleoparasitological studies. Over the past several years, our study series on Korean mummies has yielded very pertinent …

An Evaluation Of The East Indianapolis Food Desert, Angelina Qin

Undergraduate Honors Thesis Collection

The Indy East Food Desert (IEFD) appears to suffer from many common conditions noted by various scholars as food desert identifiers. Yet, its situation still remains unique. Though there is a prevalence of minority populations, low-income households, and low-education attainment levels, there are also factors of low-access, poor food options (within the limited food outlets in the neighborhoods), and poor eating habits which shape the situation of the community. In an attempt to alleviate the food desert problems, the Indy East Food Desert Coalition (IEFDC) was formed. IEFDC partnered with Butler University's Center for Urban Ecology in order to assess …

Vitamin D Status Of College Students: Implications For Health Leaders, Eileen M. Cress

Electronic Theses and Dissertations

Vitamin D deficiency is considered to be a pandemic with implications for compromised bone health and other chronic diseases. Few studies have examined vitamin D status in college-aged individuals where prevention of future health consequences is still possible. Serum vitamin D 25(OH)D status and vitamin D intake were examined in 98 college students ages 18-29 years during winter. BMI was classified as < 25and 25 or greater. Race was categorized as Caucasian or other. Overall, 69.5% had suboptimal serum vitamin D levels, <30ng/mL. Only 8 students (8.2%) met the EAR (400 IU) per day for vitamin D intake. t tests were used to determine if there were significant differences in serum vitamin D level and dietary intake based on gender, race and BMI. Significant differences were found in serum vitamin D level when compared by gender and race. Females tended to have a higher serum vitamin D level than males. Those representing minorities had lower serum vitamin D levels than Caucasians; One hundred percent of the minority students had suboptimal serum vitamin D levels. Based on these findings, dietitians should increase efforts to target college-aged individuals in educational programming related to factors affecting vitamin D synthesis, vitamin D intake, and health consequences of suboptimal vitamin D status, particularly in winter. Consideration should be given to vitamin D fortification of foods that meet the preferences of today’s consumer.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Almost 20% of children aged 6 to 11 years are obese in the United States, tripling over the last ten years. The rise in childhood obesity challenges nurses in their efforts to improve community health and sustainability. A decrease in physical activity (PA) levels has been associated with an increase in obesity. Schools have been identified as a primary setting to provide children adequate amounts of daily PA, and nurses working in the area of child health promotion can work with schools to provide opportunities for children to increase PA levels. The playground is one environment where children can increase …

Evaluating The Impact Of A Home-~Based Childhood Asthma Intervention Program In Clark County, Nevada, Mackenzie Suzanne Burns

UNLV Theses, Dissertations, Professional Papers, and Capstones

Asthma is a chronic, incurable, costly, and potentially life–threatening disease that affects an estimated 7 million children in the United States; further, more than 56,000 Nevada children are currently living with asthma. The literature suggests that a number of factors that contribute to either the development of asthma or the exacerbation of asthma symptoms in sensitive individuals can be traced to the home environment. Given that the majority of Americans spend over 90% of their time indoors, of which two–thirds are spent at home, a home–based childhood asthma intervention program represents a unique primary prevention opportunity. This pre–experimental study evaluated …

Determining The Presence Of Carbapenem Antibiotic Resistance In Clinical Isolates, Fidelis Uzoma Enyinnaya

UNLV Theses, Dissertations, Professional Papers, and Capstones

Carbapenems are β-lactam antibiotics reserved for the treatment of severe microbial infections, especially those targeting the Enterobacteriaceae. Introduced in the 1980s, carbapenems have been used successfully in hospitals, and in the 1990s resistance was discovered. Carbapenem resistance is conferred through the production of carbapenemases. In the U.S., the most common carbapenemase is Klebsiella pneumoniae carbapenemase (KPC). In 2012, the National Healthcare Safety Network reported a carbapenem resistance rate of 13.0% among Klebsiella pneumoniae infections, and indicated that the mortality rate associated with carbapenem resistant Enterobacteriaceae (CRE) infections ranged from 48.0-71.9%. According to the Food and Drug Administration (FDA), carbapenem resistance …

Health Hazards In Rental Housing: An Overview Of Clark County, Nevada, Amanda Nicole Sokolowsky

UNLV Theses, Dissertations, Professional Papers, and Capstones

A wide range of health conditions are associated with housing conditions, including asthma, respiratory infections, injuries, mental health issues, and lead poisoning. People in modern societies spend more than 90% of their time indoors, the vast majority of which is spent at home. Therefore, any new information on housing related health hazards in a population provides an opportunity for a new prevention program. Reports have shown that rental properties have more health related hazards than owner occupied housing, and rental properties are frequently occupied by low-income and minority individuals. This descriptive study intended to provide an overview of housing related …

Childhood Obesity And Familial Hypercholesterolemia: Genetic Diseases That Contribute To Cardiovascular Disease, Alyssa Caudle

Senior Honors Theses

Childhood obesity occurs as the result of an imbalance between caloric intake and energy expenditure. Genetic risk factors for obesity have become an area of research due to its permanency. Mutated genes such as Fat Mass and Obesity Associated (FTO), Leptin (LEP), Leptin Receptor (LEPR), Melanocortin 4 Receptor (MC4R), Adiponectin C1Q and Collagen Domain Containing (ADIPOQ), Proprotein Convertase Subtilisin/Kexin Type 1 (PCSK1), and Peroxisome Proliferator-Activated Receptor Gamma (PPARG) all contribute to the development of childhood obesity. In the presence of high cholesterol caused by obesity, the genetic condition known as familial hypercholesterolemia is exacerbated. Familial hypercholesterolemia is caused by a …

Analysis Of The Morbidity And Mortality Of Severe Influenza Infection In Clark County, Nevada For The 2010-2011 Influenza Season, Kindra St. Jacques, Patricia Cruz, Brian Labus

Nevada Journal of Public Health

Throughout the duration of any influenza season, influenza strains have the ability to evolve through mutation causing alterations in virulence. These changes may result in severe illness or death among susceptible populations; therefore, it is important to closely monitor influenza-associated hospitalizations and deaths. The University of Nevada, Las Vegas in collaboration with the Southern Nevada Health District analyzed data from the hospitalized influenza morbidity and mortality surveillance project for Clark County for the 2010-2011 influenza season. Among the study population (N= 158): the influenza strain type was found to be significantly associated with deaths (n= 25), vaccination status was not …

Environmental Correlates Of Physical Activity Among African-American Adults, Tim Bungum, Jennifer Pharr, Paulo S. Pinheiro, Maria Azzarelli

Nevada Journal of Public Health

The purpose of this cross-sectional study was to identify perceived environmental correlates of meeting physical activity guidelines among African-American adults living in Southern Nevada. Trained interviewers phoned potential participants who lived in the 12 zip codes of Clark County, Nevada with the highest proportions of African-American residents. Respondents (n=237) answered 52 health-related and demographic questions. Slightly less than 50% of participants met physical activity guidelines. A factor analysis procedure produced two environmental variables, neighborhood safety and environmental supports for physical activity. Age, gender and educational attainment (p<.05) predicted the meeting of those guidelines (R2=.214), while neighborhood support for physical activity, neighborhood safety, and BMI failed to do so. This finding suggests that environmental factors are not strong predictors of physical activity among African- American adults, although environmental supports for physical activity approached significance. Future studies should consider assessing additional aspects of the built environment as an influence on physical activity.

Pathogenic Mechanisms And Signaling Pathways In Plasmodium Falciparum, Jennifer L. Sedillo

USF Tampa Graduate Theses and Dissertations

Plasmodium falciparum is a human intracellular parasite that is the causative agent of a deadly form of malaria. This species alone is responsible for 200 million cases of malaria annually resulting in over 1 million deaths worldwide. The excessive mortality due to P. falciparum infection is due to its ability to cause severe pathogenesis through hyperparasitemia and cytoadherence defined as the ability of infected red blood cells to adhere to host vasculature. Cytoadherence is mediated through the export of parasite proteins to the surface of the infected red blood cell (RBC). Exported proteins have been identified but the pathway for …

Overwintering And Early Season Amplification Of Eastern Equine Encephalitis Virus In The Southeastern United States, Andrea Bingham

USF Tampa Graduate Theses and Dissertations

Eastern equine encephalitis virus (EEEV) is a highly pathogenic arbovirus that causes severe disease, with a mortality rate of approximately 30-35% in humans and 80-90% in horses. Studies dating back to the 1930's have identified many of the epidemiological and ecological aspects of the virus. However, there are several aspects of EEEV's transmission cycle that remain unclear. In the northeastern states, transmission is seasonal, peaking in the late summer months, while in Florida there is year-round transmission of EEEV. Recent phylogenetic studies have also suggested that Florida may serve as a reservoir for EEEV; the virus may periodically be introduced …

Molecular Evidence For Vector Implication Of Onchocerca Lupi In Los Angeles County, Ca, Shanna June Bolcen

USF Tampa Graduate Theses and Dissertations

Onchocerca is a genus of roundworm most commonly associated with the human infection onchocerciasis, or river blindness. While typically a zoonotic infection of ungulate populations, canine cases (Onchocerca lupi) have been identified in the United States and Greece. In 2012, Los Angeles County, Veterinary Public Health Program identified 3 cases of Onchocerca spp. infections in domestic canines. Samples from the ensuing blackfly collections were sent to the Global Health Infectious Disease Research Unnasch Laboratory for parasite isolation and vector species identification. Species-specific primers were designed and optimized for O. lupi using a non- specific cytochrome oxidase (COI) gene target (689bp) …

Heterogeneity, Not Randomness, Sets Challenges For Quantitative Genetics And Epidemiology: A Response To Davey Smith’S “Gloomy Prospect”, Peter J. Taylor

Working Papers on Science in a Changing World

Social epidemiologist Davey Smith (2011) argues that epidemiologists should accept a gloomy prospect: considerable randomness at the individual level means that they should keep their focus on modifiable causes of disease at the population level. The difficulty epidemiology has had in moving from significant population-level risk factors to improved prediction of cases at an individual level is analogous to the lack of success in the search for systematic aspects of the non-shared environmental influences that human quantitative genetics claims overshadow common environmental influences (e.g., the family’s socioeconomic status which siblings have in common). This article responds to the argument and …
