Environmental Justice For Harris County: Why Low-Income Black And Latino Communities Are Last In Regards To Initial Assessment, Classification, And Remediation For Superfund Site., Terra Bianca Gaines

Theses (Pre-2016)

Superfund sites are well known to pose serious risks to the health of the individuals living within close proximity. For this reason, the United States federal government passed the Comprehensive Environmental Response, Compensation, and Liability Act on December 11, 1980, designed to bestow power of prosecution and jurisdiction over potentially hazardous sites to the Environmental Protection Agency. Nonetheless, a large number of low income African American and Hispanic neighborhoods have been shown to be neglected in regards to superfund site initial assessment, classification, and remediation. This thesis examines' whether race, low income and secondary educational levels, are factors causing the …

Pelargonium (Geraniaceae) And The Long-Tongued Fly Pollination Guild: Coevolution And Polymorphism In A Specialized Pollination System, Emily M. Blank

Honors Scholar Theses

In South Africa, a group of long-tongued flies and the flowering plants they pollinate form a unique and diverse pollination guild system almost entirely endemic to the Greater Cape Floristic Region. This system makes up only a small portion of the biodiversity of the Region, but it is likely a key to understanding the evolutionary processes that have lead to the observed biodiversity. Aside from its unusual pollinators, this guild system is of particular interest due to the extremely labile morphology of both the fly species and the associated flowering plant species, which geographically vary significantly in proboscis lengths and …

The Effect Of Repeated Mild Traumatic Brain Injury On Ventricular Volume And Microglial Activation, Lillian Rose Talbot

Honors Scholar Theses

As the leading cause of death and disability in individuals under the age of 45-years-old, Traumatic Brain Injury (TBI) is a public health crisis that demands the attention of the scientific and medical community [28]. The majority of all TBIs that occur in the United States each year are a non-deadly yet detrimental form of closed brain injury known as mild TBI (mTBI) or concussion [6]. Athletes, young people and military personnel all face a high risk of acquiring mTBI as a result of their environments. In our study we have chosen to model repeated mTBI (rmTBI) in the mouse …

Factors Associated With Abnormal Weights In Infants In The First Year Of Life: Results From The 2010 National Ambulatory Medical Care Survey, Nikaela R. Larossa

Honors Scholar Theses

Purpose: To examine the predictors associated with abnormal infant weights for lengths in the first year of life as seen in ambulatory care settings.

Data Sources: A secondary data analysis was conducted using the 2010 National Ambulatory Medical Care Survey (NAMCS), in which practitioners documented single patient visits. World Health Organization (WHO) growth charts and recommendations were used to evaluate infant weight for length. Of the total visits, 603 infants were less than one year old, and 595 infants were within the length range of the WHO growth charts. Of the 595 cases, 13.6% were underweight, 5.5% were overweight, 41.2% …

Assessing The Relationship Between The Blood-Air Partition Coefficient And Fractional Uptake Of Inspired Halothane, Acetone, And Ethanol Vapors In The Airways Of The C57bl/6j Mouse, Joshua Baruch Baldino

Honors Scholar Theses

The following series of studies investigates the elimination and uptake trends of halothane, acetone, and ethanol vapors in the airways of C57BL/6J mice. These vapors were chosen because they span a wide range of solubilities, as indicated by their blood-air partition coefficients, and are not associated with any significant airway metabolism or reactivity with tissue substrates in vivo. Mice were exposed to a homogeneous vapor mixture containing a 1:1:1 ratio of halothane, acetone, and ethanol at relative concentrations of approximately 10 ppm. Exposure studies were performed with mice in two states, conscious and deceased, in order to provide control …

Numerical Assessment Of Sequence Conservation In Flu-Virus Hemagglutinin, Scott S. Norton

Honors Scholar Theses

The flu virus was investigated to find a common recognition domain to which an antibody against human-infected viruses can bind. If such a target site is structurally and electrostaticly conserved or invariant, only a single antibody would be required to attack the virus in all cases. The sequence of one of the viral surface proteins contains 24 amino acids that do not vary through mutation. However, these amino acids are neither contiguous in sequence or in space, and the ones that are associated with each other are not readily accessible to an antibody. They do provide a first impression of …

An Animal Model Of The Motivational Symptoms Of Depression: Testing The Antidepressant Desipramine On An Effort-Related Choice Task, Samantha L. Collins

Honors Scholar Theses

Patients with depression, schizophrenia, and other related disorders often show effort-related motivational symptoms such as anergia, psychomotor slowing, lassitude, and fatigue. Several studies have indicated that dopamine (DA) within the nucleus accumbens (NAc) is involved in the regulation of effort-related behavior. Interference with NAc DA alters response allocation in effort related choice procedures, biasing animals towards the alterative that can be obtained with minimal effort. Previous studies have shown that administration of the vesicular monoamine transporter-2 (VMAT-2) inhibitor tetrabenazine (TBZ) shifts behavior in rats responding on the FR5/chow choice procedure causing a decrease in lever pressing and a compensatory increase …

Characterization Of Udp-Arabinopyranose Mutase Genes In The Arabidopsis Cell Wall Mutant Mur5, Christopher A. Hart

Honors Scholar Theses

The genome of Arabidopsis thaliana contains several coding regions for UDP-arabinopyranose mutases (UAMs) that are also known as reversibly glycosylated polypeptides (RGPs). The mur5 cell wall mutant of Arabidopsis shows a 30% decrease in cell wall arabinose content, and a missense mutation in the Reversibly Glycosylated Polypeptide 2 gene was recently proposed to cause this mutant phenotype. Through a traditional complementation analysis, mur5 and a T-DNA insertion mutant in the RGP2 gene were shown not to complement each other, indicating that the two genes are mutant alleles of the same locus. The mur5 SNP located in RGP2 caused a more …

Modeling The Adaptive Immune Response To Mutation-Generated Antigens, Rory J. Geyer

Honors Scholar Theses

Somatic mutations may drive tumorigenesis or lead to new, immunogenic epitopes (neoantigens). The immune system is thought to represses neoplastic growths through the recognition of neoantigens presented only by tumor cells. To study mutations as well as the immune response to mutation-generated antigens, we have created a conditional knockin mouse line with a gene encoding, 5’ to 3’, yellow fluorescent protein (YFP), ovalbumin (which is processed to the immunologically recognizable peptide, SIINFEKL), and cyan fluorescent protein (CFP), or, YFP-ovalbumin-CFP. A frame shift mutation has been created at the 5’ end of the ovalbumin gene, hence YFP should always be expressed, …

Heroes To Horrors: Metamorphosis As Combat Trauma In The Mythology Of The West, Thomas Passarelli

Honors Scholar Theses

A Multiscale Analysis Of Gene Flow For The New England Cottontail, An Imperiled Habitat Specialist In A Fragmented Landscape, Lindsey E. Fenderson, Adrienne I. Kovach, John A. Litvaitis, Kathleen M. O'Brien, Kelly M. Boland, Walter J. Jakubas

New Hampshire Agricultural Experiment Station Publications

Landscape features of anthropogenic or natural origin can influence organisms' dispersal patterns and the connectivity of populations. Understanding these relationships is of broad interest in ecology and evolutionary biology and provides key insights for habitat conservation planning at the landscape scale. This knowledge is germane to restoration efforts for the New England cottontail (Sylvilagus transitionalis), an early successional habitat specialist of conservation concern. We evaluated local population structure and measures of genetic diversity of a geographically isolated population of cottontails in the northeastern United States. We also conducted a multiscale landscape genetic analysis, in which we assessed genetic discontinuities relative …

Variation In Vegetation And Microbial Linkages With Slope Aspect In A Montane Temperate Hardwood Forest, Frank S. Gilliam, Radim Hédl, Markéta Chudomelová, Rebecca L. Mcculley, Jim A. Nelson

Plant and Soil Sciences Faculty Publications

Plant ecologists have long been interested in aspect-related contrasts of montane forests. Few studies have assessed correlation (linkage) among vegetation strata; fewer have included soil microbial communities. This study assessed contrasts in overstory, spring herbaceous, and soil microbial communities between northeast (NE) - and southwest (SW) -facing slopes in a second-growth West Virginia hardwood forest. We addressed three questions: (1) how do soil microbial, herbaceous layer, and overstory communities vary with slope aspect? (2) do forest vegetation strata and soil microbial communities exhibit linkage? (3) do biotic relationships and linkage vary with slope aspect? Moisture, organic matter, pH, soil NO …

Heavy Drinking Behaviors And Parental Influence Among Greek Affiliated College Students, Melodie Harris

Electronic Theses and Dissertations

Heavy drinking behaviors have been observed in relation to fraternity and sorority membership. Some have argued that this relationship persists as a result of the drinking-conducive social environments of Greek organizations, but others have suggested that this relationship may be spurious. Using data from The Harvard School of Public Health College Alcohol Study (n = 10,904) the link between Greek affiliation, alcohol consumption, and parental influence was examined through the lens of social learning theory. It was hypothesized that members of Greek organizations would report higher levels of drinking compared to others and that the inclusion of the variable of …

An Inventory Of Evidence-Based Health And Wellness Assessments For Community-Dwelling Older Adults, Elliott David Brent, Matthew Jordan Carlson

Dissertations, Masters Theses, Capstones, and Culminating Projects

It is estimated that by 2020 older adults will makeup one fifth of California's population. Many of these older adults are living in the community and are maintaining their independence. In order to help the older adults to maintain their independence, occupational therapists are turning to the newly emerged wellness promotion model to guide their practice. The wellness promotion model is a holistic model that addresses six domains of wellness (intellectual, spiritual, physical, social, emotional, and vocational). One of the concerns in using this model to guide the emerging practice area in occupational therapy is that there is little information …

Long-Term Physical And Mental Health Effects Of Domestic Violence, Kavita Alejo

Themis: Research Journal of Justice Studies and Forensic Science

Domestic violence is an issue affecting people of all ages, races, genders, and sexual orientations. Violence against men and same-sex domestic violence are often considered less of a threat to society and to the people involved, but it is important to understand that male-on-female violence, female-on-male violence, and same-sex violence all involve serious consequences to the victim’s and batterer’s short- and long-term health. This paper determines whether men or women suffer from more long-term health problems caused by domestic violence by comparing the currently published statistics on the prevalence of domestic violence in heterosexual and homosexual relationships, and analyzing the …

The Lingering Killer: Agent Orange, Sharon Ungerfeld

Themis: Research Journal of Justice Studies and Forensic Science

This paper explores the utilization of the chemical herbicide, Agent Orange, as it was sprayed over Vietnam during the Vietnam War in 1961 to 1971. The United States government, military, and corporations acted irresponsibly by creating the chemical and spraying it as a war tactic. The outcome of the spraying includes detrimental socioeconomic impacts, environmental degradation, and health problems. The socioeconomic impact is explained with statistics and an explanation of loss of job and education capabilities. With data on the destroyed trees and vegetation, this paper demonstrates the degree to which the environment faced harm. The health effects of Agent …

Characterization Of T-Bet And Eomes In Peripheral Human Immune Cells., James J. Knox, Gabriela L. Cosma, Michael R. Betts, Laura M. Mclane

Department of Microbiology and Immunology Faculty Papers

The T-box transcription factors T-bet and Eomesodermin (Eomes) have been well defined as key drivers of immune cell development and cytolytic function. While the majority of studies have defined the roles of these factors in the context of murine T-cells, recent results have revealed that T-bet, and possibly Eomes, are expressed in other immune cell subsets. To date, the expression patterns of these factors in subsets of human peripheral blood mononuclear cells beyond T-cells remain relatively uncharacterized. In this study, we used multiparametric flow cytometry to characterize T-bet and Eomes expression in major human blood cell subsets, including total CD4(+) …

Theses and Dissertations - UTB/UTPA

Anthropogenic global climate change is a large scale threat to biodiversity. Species distribution models (SDMs) were created to assess the possible effects of climate change on the distribution of 12 Plestiodon lizards of Mexico. Species presence data was obtained from online databases, literature, and field data. Occurrences were correlated with 19 climatic variables from www.worldclim.org to model species' current suitable habitat. These models were then projected to future (2050) conditions for which bioclimatic information was downloaded from the CCAFS website. Forecasts were made using 4 General Circulatory Models, 2 IPCC scenarios, and the software MaxEnt. Models were replicated 10 times …

A Screening Platform For Identification Of Compounds That Inhibit Protein Synthesis In Pseudomonas Aeruginosa, Yanmei Hu

Theses and Dissertations - UTB/UTPA

Pseudomonas aeruginosa is a Gram-negative pathogenic bacteria and a common cause of nosocomial infections. This pathogen has recently garnered attention due to its pan-resistance. We have developed a poly(U) mRNA-directed aminoacylation/translation (A/T) protein synthesis system from P. aeruginosa. The concentration of each component of the system has been arrived at through multiple rounds of optimization. Poly-phenylalanine synthesis in the system was monitored using scintillation proximity assays (SPA). This system has been used to screen two natural compound libraries (>1100) and a number of the compounds that inhibit greater than 50% of the activity of the system have been identified. …

Theses and Dissertations - UTB/UTPA

Soil fertility and plant nutrition is crucial for a better yield and consistent harvest in the Rio Grande Valley for local farmers growing citrus trees. A field of oranges and a field of grapefruits were monitored and nutrition deficiencies were noticed that played an important role during fruit set. Soil samples that were taken throughout the year were analyzed via a carbon dioxide extraction method that mimics the way plants naturally take up nutrients or extract nutrients from every soil type. Macronutrients such as the N, P, K, Na, Ca, Mg and some of the micronutrients (Zn, Fe, Mn, and …

Rates Of Evolution And Point Mutations Of Bacterial Plant Pathogens Compared To Bacterial Vertebrate Pathogens, Alejandro Cantu

Theses and Dissertations - UTB/UTPA

The relationship between a pathogen and its host is a constant interaction; as the host evolves defense mechanisms to protect itself from the pathogen, the pathogen will evolve in order to evade them. During this evolutionary process, the genomes of bacterial pathogens can change due to different selection pressures exerted by the immune system of their respective hosts. This study aimed to determine how differences in selection pressures affect the evolution of plant and vertebrate pathogens. The focus of this study was to analyze population level changes in conserved genes, as well as species level changes in the Type III …
