The Beast With Many Heads: Situational And Dispositional Differences In Physiological, Subjective, And Behavioral Responses To Social Rejection, Ellyn C. Maese

Psychology Theses, Dissertations, and Student Creative Activity

Threats to humans’ deep-rooted social needs are associated with strong physiological, emotional, and behavioral responses that are linked to systems for physical pain responses. Yet, prior research has also revealed inconsistencies in responses to social threats, which may be related to differences in situational or dispositional factors. In exploration of these potential explanations, the proposed research aims to investigate physiological, subjective, and behavioral responses to two distinct types of social threat experiences. This study will involve analyzing data collected from a sample of 127 students at a midwestern state university who participated in a laboratory experiment in which they faced …

Methenamine Prophylaxis Reduces Recurrent Urinary Tract Infections, Salwan Al Hani, Matthew Sims

Posters

• Recurrent urinary tract infections (UTIs) are the most common outpatient infection in the US and are often managed with antibiotics in clinical practice.
• A recurrent UTI is defined as 2 or UTIs each 6 months or 3 or more UTIs each year.
• Methenamine is an antiseptic compound approved by the FDA to prevent rUTIs but is seldom used in clinical practice.
• Under acidic conditions, methenamine is converted to 6 molecules of formaldehyde, a compound which prevents bacterial growth.
• This study seeks to determine the effectiveness of methenamine for prevention of recurrent UTIs.

A Meta-Analysis For Laboratory Diagnostics For Coccidioidomycosis, Mary C. Cowen

Biological Sciences Undergraduate Honors Theses

Coccidioidomycosis, commonly referred to as Valley Fever, is a fungal infection found in arid regions of the southwestern United States and Mexico. Infection occurs through inhalation of airborne spores from Coccidioides species, Coccidioides immitis and/or Coccidioides posadasii, and proceeds in both pulmonary and disseminated fashions. Approximately 60% of patients with coccidioidomycosis remain asymptomatic, while 40% will experience symptoms. Within the literature, there are no papers that summarize sensitivity and specificity values between different tests; therefore, this paper presents sensitivity and specificity results across different tests and companies (Meridian, IMMY, and MiraVista).

A Multimodal Approach To Decreasing Hesitancy Of The Influenza Vaccine In The Family Care Setting, Carley J. Ellenberger

Evidence-Based Practice Project Reports

The uptake of the influenza vaccine is the most effective and proactive action an individual can take to defend themselves against the influenza outbreak each season; therefore, it is recommended that everyone at least six months of age and older should receive the annual flu vaccine (CDC, 2022; WHO, 2023). Unfortunately, influenza vaccine hesitancy is demonstrated on a global level affecting the uptake compliance annually each influenza season despite the millions of people that experience influenza symptoms annually (CDC, 2022, WHO, n.d.; Healthy People 2030, n.d.). The PICOT question for this project was in adults, over the age of 18, …

The Use Of Whole Blood In Increasing The Survivability Of Combat Wounded Troops From 1940 To 1953, Devin Sweet

LSU New Orleans Theses and Dissertations

Humans have been experimenting with new ways to kill each other for millennia, and for just as long, doctors have been experimenting with methods to improve survivability of those wounded. The 20^th century was one of the bloodiest period in human history; war claimed over one hundred million lives. With the scourge of disease more easily managed, the medical communities came to address the one wound that historically cost most lives – bleeding to death. Shock and exsanguination can kill a person within thirty seconds to two minutes, and finding ways to mitigate that outcome has been the subject …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The COVID-19 pandemic was a catastrophic global event that exacerbated public health issues and disparities, especially in socially vulnerable communities. Thus, this study examines areas classified by the CDC's Social Vulnerability Index (SVI) metric, which assesses vulnerable communities experiencing adverse events through sixteen social determinants that impact health. The purpose of this study will be to determine if (1) COVID-19 testing rates and/or COVID-19 vaccination rates mediate SVI and COVID-19 prevalence rates and (2) if COVID-19 testing rate and COVID-19 vaccination rates serially mediate SVI and COVID-19 prevalence rates. In order to achieve this, census tracts within Southern Nevada will …

Self-Perception And Positive Stereotype Endorsement, Aileen Lovitt

UNLV Theses, Dissertations, Professional Papers, and Capstones

The origin and reasoning behind the use of racial stereotypes has been a point of interest for researchers over the years. Many different theories have been proposed including those related to cognitive, evolutionary, and motivational explanations. However, most of these theories and the research backing them primarily focus on negative stereotyping. The origin of positive stereotyping, which also has negative implications associated with their use, has not been evaluated fully. Previous research has suggested that the motive to preserve self-worth and positive self-concept may play a role in stereotype endorsement. Two studies were conducted with the purpose of investigating whether …

This doctoral project discusses aversive behaviors, social-emotional learning, the Zones of Regulation and Friendzy social-emotional learning programs, caregiver education, and caregiver self-efficacy. This project highlights the importance of including caregivers in effective school-based social-emotional learning programs by exploring caregivers' self-efficacy when provided education on school-based social-emotional learning techniques.

Examining The Risks And Resilience Of Older Adults Living With Hiv/Aids: Qualitative Community-Based Participatory Research Studies In Southern Nevada, Brandon Ranuschio

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the height of the HIV pandemic in the 1980s, medical interventions have significantly increased the life expectancy of people living with HIV/AIDS (PLWH) and made HIV/AIDS a livable, chronic health condition. Because of this, PLWH have been living longer lives and thriving with the help of HIV sector healthcare and service providers. However, with their longer life expectancy, older PLWH have been experiencing other health challenges. One such challenge is the risk of developing HIV-Associated Neurocognitive Disorder (HAND), which is a condition that affects up to 50% of PLWH at some point in their lifetime, with middle-aged and older …

Characterizing The Role Of Pa5189 Of Pseudomonas Aeruginosa In Deletion And Overexpression Mutants, Seh Na Mellick

Theses/Capstones/Creative Projects

In the context of rising multidrug resistance in biofilm-forming pathogens like Pseudomonas aeruginosa, this study investigates the role of the understudied transcription factor PA5189 in antibiotic resistance and biofilm formation. PA5189 deletion and overexpression mutants were created in a parent P. aeruginosa strain using pEX18Tc-based recombinant suicide vectors, with genotypic verification of putative triparental conjugants achieved through restriction digestion and PCR. The study revealed that PA5189 overexpression significantly increases resistance to commonly used broad spectrum antibiotics such as ciprofloxacin and imipenem. Additionally, differential expression of PA5189 was found to notably affect biofilm formation, with variations contingent on the nutrient …

Community Health Assessment Collaboration: Implementing A Joint Assessment Between A Healthcare System And A Local Health Department, Briar L. Deen

Dissertations: Doctor of Public Health

Non-profit hospitals and local health departments (LHDs) often complete community health assessments (CHAs) to help understand the needs of their community and develop implementation strategies to address the community needs. Hospitals and LHDs in the same community often develop separate CHAs with similar results leading to overlap in work and funds. This project aimed to address this issue in the Dallas-Fort Worth Metroplex by convening one local health department, Denton County Public Health, and one non-profit healthcare system, Texas Health Resources, to leverage resources from each other to build a joint CHA. The Mobilizing for Action through Planning and Partnerships …

Determining The Antimicrobial Activity And Permeabilizing Effects Of Polyunsaturated Fatty Acids And Piscidins On Vibrio Parahaemolyticus And Vibrio Vulnificus, Christina Harris

Honors Theses

Antimicrobial peptides (AMPs) are found in all organisms and have gained attention for their effectiveness against a variety of pathogens. Piscidins are AMPs that were discovered in mast cells of vertebrates, mostly within marine animals, and are an important part of the innate immune system due to their potent antimicrobial properties. Piscidin 1 (P1) and piscidin 3 (P3) are found within sea bass and have different antimicrobial activities. P1 exhibits strong membrane disruptive properties, while P3 goes through the membrane to the targeted DNA. These piscidins can experience metalation with copper (Cu2+) which enhances their antimicrobial activity in vitro (P1-Cu2+ …

Brain and Mind Institute

Two of every three persons living with dementia reside in low- and middle-incomecountries (LMICs). The projected increase in global dementia rates is expected toaffect LMICs disproportionately. However, the majority of global dementia care costsoccur in high-income countries (HICs), with dementia research predominantly focus-ing on HICs. This imbalance necessitates LMIC-focused research to ensure thatcharacterization of dementia accurately reflects the involvement and specificities ofdiverse populations. Development of effective preventive, diagnostic, and therapeu-tic approaches for dementia in LMICs requires targeted, personalized, and harmonizedefforts. Our article represents timely discussions at the 2022 Symposium on Demen-tia and Brain Aging in LMICs that identified the foremost …

Mismatch Repair Deficient Neoantigen And Associated Circulating T-Cell Receptor Repertoires In Lynch Syndrome, Ana Bolivar

Dissertations and Theses (Open Access)

Lynch Syndrome (LS) is the most common inherited colorectal cancer (CRC) syndrome. It constitutes the perfect model to understand DNA mismatch repair deficient (MMRd) carcinogenesis, which underlies 15% of early-stage CRC. LS patients develop MMRd tumors with high loads of shared neoantigens (neoAgs), which are recognized by the immune system. Previous research has concentrated on discovering neoAgs and their potential as targets for vaccines in LS patients. However, these studies have primarily identified shared neoAgs from cancers, lacking detailed information on targetable neoAgs present in precancerous lesions. Understanding this landscape of pre-cancer derived neoAgs is crucial for intercepting cancer development …

Exploring Subtype C Hiv-1 Tissue Reservoirs And The Impact Of Cannabis Use In Virally Suppressed African Individuals, Zhou Liu

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Antiretroviral therapy (ART) has dramatically prolonged the lives of people living with HIV (PLWH), but it is not curative as it cannot eliminate integrated HIV-1 proviruses in different tissue reservoirs. Even though subtype C HIV-1 accounts for almost half of global HIV-1 infections, few studies had evaluated HIV-1 reservoirs for this subtype. Many co-factors, including the lifestyle factor cannabis use, have been investigated for their potential effects in HIV-1 infection. However, only limited information exists regarding cannabis’s effects on HIV-1 infections in vivo, and the impact of cannabis use on HIV-1 parenchymal tissue reservoirs is unexplored. This dissertation aims to …

Pipecolic Acid And Novel Insights Into Cerebral Malaria, Akua E. Mensah

Theses and Dissertations

Cerebral malaria (CM), a severe manifestation of Plasmodium infection, prompts our investigation into the nuanced role of pipecolic acid in its pathophysiology. To unravel the molecular intricacies, we conducted in vitro lysine labeling techniques of mice infected with P. berghei ANKA parasites, and human P. falciparum grown in vitro, aiming to discern the impact of Plasmodium on pipecolic acid production. Previous observations indicated an elevation in pipecolic acid levels correlating with neurological decline in children with CM. In our study, confirming elevated pipecolic acid presence in the plasma and brain tissues of CM patients and the animal model of CM, …

Cost Saving And Resource Limited Public Health Interventions In Southeast Asia, Amanda Blackwelder

Electronic Theses and Dissertations

Background: Public health interventions are any activity with the objective of improving human health such as preventing or curing disease, reducing the severity or duration of a disease, or assisting in regaining function after a disease or injury. These interventions are known to be impactful; however, those living with the highest burden of disease such as individuals in low- and middle-income countries have limited money and resources to successfully implement these interventions. Southeast Asian countries are among some of the middle-income countries effected by the lack of affordable interventions. The aims of this study were to assess cost saving and …

How Monitoring Food Is Protecting People, Grace Sugden

Capstone Projects and Master's Theses

While the issue of food safety has always been a concern for humanity, what that looks like has changed drastically over time. Instead of trying to judge if a stream has safe drinking water, consumers are now faced with deciding which preservatives and pesticides they expose themselves to. With the multitude of United States agencies tasked with protecting the public, standards and quality control processes should be transparent and efficient. Since the creation of the Bureau of Chemistry, numerous acts have been passed that regulate ingredients, processing procedures, and minimize contamination risks. When a spoiled product enters the food web, …

The Constitutively Active Form Of A Key Cholesterol Synthesis Enzyme Is Lipid Droplet-Localized And Upregulated In Endometrial Cancer Tissues, Hudson W Coates, Tina B Nguyen, Ximing Du, Ellen M Olzomer, Rhonda Farrell, Frances L Byrne, Hongyuan Yang, Andrew J Brown

Faculty, Staff and Student Publications

Cholesterol is essential for both normal cell viability and cancer cell proliferation. Aberrant activity of squalene monooxygenase (SM, also known as squalene epoxidase), the rate-limiting enzyme of the committed cholesterol synthesis pathway, is accordingly implicated in a growing list of cancers. We previously reported that hypoxia triggers the truncation of SM to a constitutively active form, thus preserving sterol synthesis during oxygen shortfalls. Here, we show SM truncation is upregulated and correlates with the magnitude of hypoxia in endometrial cancer tissues, supporting the in vivo relevance of our earlier work. To further investigate the pathophysiological consequences of SM truncation, we …
