Mixed Methods Approach To Assess ‘Placental Opioid-Enhancing Factor’ Activity Within ‘Alternative’ Health Contexts Of Human Maternal Placentophagy, Jacob C. White May 2024

Mixed Methods Approach To Assess ‘Placental Opioid-Enhancing Factor’ Activity Within ‘Alternative’ Health Contexts Of Human Maternal Placentophagy, Jacob C. White

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rats with elevated opioid levels experience an even greater increase in pain threshold after placenta or amniotic fluid consumption via placental opioid-enhancing factor (POEF) in the afterbirth. POEF only enhances opioid hypoalgesia; it cannot produce hypoalgesia alone. Although the POEF molecule remains unidentified and its efficacy in humans is unknown, it could be a safe, novel pain treatment. People who consume placenta as an alternative postpartum health practice are ideal for testing POEF bioactivity. Though rat models show that bioactive POEF is highly sensitive, some forms of the practice in humans may conserve POEF.

This project is the first attempt …

Student Scholar Symposium Abstracts and Posters

Retraining impaired gait is essential in post-stroke recovery. This project aims to determine between day variability of spatiotemporal gait measures in treadmill walking post-stroke to differentiate between changes due to the intervention and measurement errors due to between day test-retest variability. Six individuals post-stroke performed a two-minute walk test at a self-selected speed (SSS) for two consecutive days. SSS was assessed through the six-minute walk test. Reflective markers were placed on anatomical landmarks (van den Bogert et al. 2013). The heel markers were used for step detection. We calculated spatiotemporal parameters: stride length, stride time, step length, stance time, and …


Synthesis Of Neoglycoproteins As Potential Biomarkers For Chagas Disease And Cutaneous Leishmaniasis Caused By Leishmania (Viannia) Braziliensis, Eileni Rodriguez Gil May 2024

Synthesis Of Neoglycoproteins As Potential Biomarkers For Chagas Disease And Cutaneous Leishmaniasis Caused By Leishmania (Viannia) Braziliensis, Eileni Rodriguez Gil

Open Access Theses & Dissertations

Protozoan parasites are responsible for causing numerous diseases in humans and mammals worldwide. Among them are Chagas disease (CD), caused by the parasite Trypanosoma cruzi (T. cruzi), and tegumentary leishmaniasis (TL), caused by the parasite Leishmania (Viannia). Both diseases coexist in many regions of Latin America, and current hurdles to differentially diagnose them and determine chemotherapy success need to be overcome. CD can be diagnosed by traditional serological tests and polymerase chain reaction (PCR), but disadvantages of these methods are that they may produce false negatives because the antigens used in commercial CD kits are not conserved across all T.cruzi …

Honors Theses

Within recent years, there has been increased attention to the growing physician shortage across the United States. This shortage has placed substantial strain upon regions of lower healthcare access, particularly those of rural regions such as much of the state of Mississippi. As rural healthcare providers are placed under more strenuous conditions, they encounter issues of increased patient volume, lack of a trauma team, or adequate transportation to higher-level care facilities. These issues may exacerbate the present inequities in cost of living, access to adequate healthcare, and the distress caused by these concerns. Individuals with epilepsy are one cohort with …


Screening Environmental Soil Samples For Antibiotic Production, Paige Mattick Apr 2024

Screening Environmental Soil Samples For Antibiotic Production, Paige Mattick

SACAD: Scholarly Activities

Antibiotic resistance is a detrimental worldwide challenge, producing bacterial infections that are progressively more difficult to treat and cure. To attempt to help alleviate this issue, we screened soil samples for the presence of antibiotic-producing microorganisms. Soil samples were collected and diluted to 1:100 and 1:1000 ratios of soil and distilled water. These soil mixtures were then streaked onto tryptic soy agar (TSA) plates and incubated at 30℃ until colonies developed. These colonies were then selected and plated on a lawn of Serratia marcescens, which was utilized as the target organism.

Serratia marcescens was selected due to its known resistance …


Hedgehog Signaling And Congenital Disorders; The Case Of Anencephaly And Polydactyly, Joshua Towery Apr 2024

Hedgehog Signaling And Congenital Disorders; The Case Of Anencephaly And Polydactyly, Joshua Towery

First-Year Research Immersion (FRI) Scholarship

The Hedgehog pathway is a fundamental signaling pathway in the human body; involved in carcinogenesis, stem cell maintenance, as well as limb patterning in embryonic development. Originally discovered in drosophila, their initial discovery, and subsequent analysis revealed many novel pieces of information about the mechanisms inside the human body, as many core components of the signaling pathway are carried over from fruit flies to humans. Because of the key roles hedgehog signaling plays in human development, dysfunction and mutations in the pathway can be detrimental. This review will focus on two congenital birth defects thought to be caused by hedgehog …


Mycoplasma Pneumoniae: Long-Term Effects On The Lungs, Alyssa David Apr 2024

Mycoplasma Pneumoniae: Long-Term Effects On The Lungs, Alyssa David

Posters - 2024

Mycoplasma pneumoniae is a bacterium responsible for causing pneumonia in the lungs. M. pneumoniae is responsible for an average of 2 million cases of bacterial pneumonia in the United States each year (ASM Journal). When M. pneumonia infects the lungs, it releases community-acquired respiratory distress syndrome (CARDS toxin), which is capable of two enzymatic functions, vacuolization and ADP-ribosylation. ADPribosylation is found in the N-terminal domain of the protein, and the glutamic acid at amino acid residue 132 is critical for enzymatic function. There is evidence that the vacuolization function is encoded by the C-terminal of the protein. Preliminary findings in …

Impairment Of The Glial Phagolysosomal System Drives Prion-Like Propagation Of Huntington’S Disease, Graham Davis Feb 2024

Impairment Of The Glial Phagolysosomal System Drives Prion-Like Propagation Of Huntington’S Disease, Graham Davis

Theses and Dissertations

The ability of glia to tightly regulate neuronal health and homeostasis in the CNS is conserved across species. Yet, despite the ability to degrade protein aggregates, glia are vulnerable to the accumulation of neurotoxic amyloid aggregates during neurodegenerative disease progress, and even exacerbate their spread. A developing narrative highlights glia as a double-edged sword in neurodegenerative diseases: initially capable of dynamically responding to amyloid aggregate-ladened dying neurons but also capable of inducing chronic inflammation and creating seeding-competent amyloid oligomers. Thus, uncovering the mechanisms that allow glia to control aggregate deposition while preventing the neurotoxic effects and seed generation is vital …


Targeting Strategies To Optimize The Therapeutic Potential Of Gold Compounds Against Her2-Positive Breast Cancers, Afruja Ahad Feb 2024

Targeting Strategies To Optimize The Therapeutic Potential Of Gold Compounds Against Her2-Positive Breast Cancers, Afruja Ahad

Dissertations, Theses, and Capstone Projects

The overexpression of HER2 accounts for 20-30% of breast cancer tumors and not only serves as a marker for poor predictive clinical outcomes but also as a target for treatment. Antibody-drug conjugates (ADCs) combine the selectivity of monoclonal antibodies (mAbs) with the efficacy of chemotherapeutic drugs to provide targeted treatment without toxicity to normal tissue. Most of the ADCs currently in the clinic for cancer chemotherapy are based on complex organic molecules. In contrast, the conjugation of metallodrugs to mAbs has been overlooked when there is enormous potential in this area with the resurgence of metal-based drugs as prospective cancer …


Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto Feb 2024

Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto

Dissertations, Theses, and Capstone Projects

Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …

There is still incomplete knowledge of which Mycobacterium tuberculosis (Mtb) antigens can trigger distinct T cell responses at different stages of infection. Here, a proteome-wide screen of 20,610 Mtb-derived peptides in 21 patients mid-treatment for active tuberculosis (ATB) reveals IFNγ-specific T cell responses against 137 unique epitopes. Of these, 16% are recognized by two or more participants and predominantly derived from cell wall and cell processes antigens. There is differential recognition of antigens, including TB vaccine candidate antigens, between ATB participants and interferon-gamma release assay (IGRA + /−) individuals. We developed an ATB-specific peptide pool (ATB116) consisting of epitopes exclusively …


The Effect Of Various Polyphenols On Associative Memory Loss And Dementia In A Drosophila Melanogaster Model Of Alzheimer’S Disease, Anagha Gowda Jan 2024

The Effect Of Various Polyphenols On Associative Memory Loss And Dementia In A Drosophila Melanogaster Model Of Alzheimer’S Disease, Anagha Gowda

Journal of the South Carolina Academy of Science

Alzheimer’s Disease (AD), a prominent neurodegenerative disease (NDD), is the seventh leading cause of death in the United States; however, little is known about prevention. As a result, polyphenols (plant-based compounds) and other natural substances have been studied for their therapeutic potential in improving cognition and memory in AD cases. While the impacts of each polyphenol (phenolic acids, flavonoids, stilbenes, and lignans) contain fundamental similarities, each varies slightly in its impacts on the brain.The purpose of this study was to examine the impacts of polyphenol subgroups on associative memory in AD, tested by building an olfactory association, through the use …
