Substance Use Disorders And The Behavioral Effects Of Novel And Existing Compounds, Sarah Uribe Mar 2023

Substance Use Disorders And The Behavioral Effects Of Novel And Existing Compounds, Sarah Uribe

Theses and Dissertations

These investigations aimed to study the effects of experimental compounds for use in treating and preventing substance use disorders, particularly opioid use disorder (OUD) and alcohol use disorder (AUD). Identifying and testing potential medications for these two diseases is critical since current FDA-approved medications are only modestly effective, and addiction continues to spread. We previously demonstrated that co-administration of morphine and MP-III-024 produced synergistic effects in hot plate and von Frey assays. This study evaluated whether MP-III-024 also produced synergistic effects in behavioral tests sensitive to the side effects of morphine. Our findings suggest that co-administration of morphine and MP-III-024 …

Decellularized Heart Extracellular Matrix As A Biomimetic Substrate For Alleviating Hipsc-Cardiac Fibroblast Activation And Enhancing Isogenic Cardiac Organoids, Charles Kerr

MUSC Theses and Dissertations

Cardiovascular disease is the constant leading cause of death worldwide. While substantial efforts have been undertaken to improve disease outcomes, the lack of adequate human cardiac tissue models exacerbates research and development costs and clinical trial failures, hampering novel therapeutic discovery. To address this, human engineered cardiac microtissues composed of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) show potential in recapitulating hallmark qualities of natural human myocardium for novel therapeutic testing, disease modeling and cardiotoxicity screening. However, as these models are engineered in vitro, they are limited in their capacity to fully recapitulate myocardium and are vulnerable to influences …


Pamam- Cyclodextrin Conjugate Upregulates Brain-Derived Neurotropic Factor In Arpe-19 Cells, Gopika Ashokan Mar 2023

Pamam- Cyclodextrin Conjugate Upregulates Brain-Derived Neurotropic Factor In Arpe-19 Cells, Gopika Ashokan

USF Tampa Graduate Theses and Dissertations

Background: Traumatic Brain Injury (TBI) is a major contributor to death and disability due to motorvehicle accidents, sports, physical abuse, and battlefield injuries. The primary insult to the brain leads to inflammation, vascular dysfunction, and oxidative stress in the brain as well as in the eye. This leads to loss of Retinal Ganglion Cells (RGCs) and downregulation of Brain derived Neurotopic Factor (BDNF). BDNF is a neurotrophic factor that binds to Tropomyosin Receptor Kinase B (TrkB) receptor to promote cell growth, survival, and differentiation. Current treatment strategies do not promote neuronal regeneration. Therefore, novel treatments are needed to restore vision …

Department of Medicine Faculty Papers

Rheumatoid arthritis (RA) is a progressive, inflammatory, autoimmune, symmetrical polyarticular arthritis. It is characterized by synovial infiltration and activation of several types of immune cells, culminating in their apoptosis and antibody generation against "altered" autoantigens. β2-microglobulin (β2m)-associated heavy chains (HCs) of HLA antigens, also known as closed conformers (Face-1), undergo "alteration" during activation of immune cells, resulting in β2m-free structural variants, including monomeric open conformers (Face-2) that are capable of dimerizing as either homodimers (Face-3) or as heterodimers (Face-4). β2m-free HCs uncover the cryptic epitopes that can elicit antibodies (Abs). We report here the levels of IgM and IgG Abs …

Intimate Conversations: A Mixed-Methods Study Of African American Father-Adolescent Sexual Risk Communication, Shanda A. Vereen

USF Tampa Graduate Theses and Dissertations

Background: Approximately 50% of African American (AA) high school students are sexually active and a large proportion of sexually active AA students report engaging in sexual risk behaviors such as not using condoms at last intercourse. Consequently, AA adolescents in the United States experience outcomes of risky sexual behaviors at high rates. Evidence shows parents have an effect on shaping adolescent attitudes, values, and beliefs regarding sex through sexual risk communication (SRC). Although parent-adolescent SRC is associated with reductions in sexual risk behaviors among AA adolescents, research has primarily focused on mothers. While parents acknowledge that SRC is traditionally viewed …

Department of Neurology Faculty Papers

Distinct lines of research in both humans and animals point to a specific role of the hippocampus in both spatial and episodic memory function. The discovery of concept cells in the hippocampus and surrounding medial temporal lobe (MTL) regions suggests that the MTL maps physical and semantic spaces with a similar neural architecture. Here, we studied the emergence of such maps using MTL microwire recordings from 20 patients (9 female, 11 male) navigating a virtual environment featuring salient landmarks with established semantic meaning. We present several key findings. The array of local field potentials in the MTL contains sufficient information …

Membrane asymmetry means that the two sides of membrane are structurally, physically and functionally different. Membrane asymmetry is largely related to the lipid sidedness and particularly to compositional (lipid head and acyl group) and physical (lipid packing order, charge, hydration and H-bonding interactions) differences in the inner and outer leaflets of lipid bilayer. Chemically, structurally and conformationally different non-covalent bound lipid molecules are physically fluid and deformable and enable to interact dynamically to form transient arrangements with asymmetry both perpendicular and parallel to the plane of the lipid bilayer. Although biological membranes are almost universally asymmetric however the asymmetry is …

Loss of synapses is the most robust pathological correlate of Alzheimer's disease (AD)-associated cognitive deficits, although the underlying mechanism remains incompletely understood. Synaptic terminals have abundant mitochondria which play an indispensable role in synaptic function through ATP provision and calcium buffering. Mitochondrial dysfunction is an early and prominent feature in AD which could contribute to synaptic deficits. Here, using electron microscopy, we examined synapses with a focus on mitochondrial deficits in presynaptic axonal terminals and dendritic spines in cortical biopsy samples from clinically diagnosed AD and age-matched non-AD control patients. Synaptic vesicle density within the presynaptic axon terminals was significantly …
