Sanders-Brown Center on Aging Faculty Publications

Apolipoprotein E ɛ4 allele is a common susceptibility gene for late-onset Alzheimer's disease. Brain vascular and metabolic deficits can occur in cognitively normal apolipoprotein E ɛ4 carriers decades before the onset of Alzheimer's disease. The goal of this study was to determine whether early intervention using rapamycin could restore neurovascular and neurometabolic functions, and thus impede pathological progression of Alzheimer's disease-like symptoms in pre-symptomatic Apolipoprotein E ɛ4 transgenic mice. Using in vivo, multimodal neuroimaging, we found that apolipoprotein E ɛ4 mice treated with rapamycin had restored cerebral blood flow, blood–brain barrier integrity and glucose metabolism, compared …

Antiviral Peptide Nanocomplexes As Potential Therapeutics For The Treatment Of Infectious Diseases, Jinjin Zhang

Theses & Dissertations

Hepatitis C Virus (HCV) is recognized as a major burden in global public health, which can be further exacerbated by several cofactors such as human immunodeficiency virus (HIV). Currently, there is no vaccine for HCV. The emergence of potent and highly specific direct-acting antivirals (DAA) has marked a new era in HCV therapy, however, the remaining issues like affordability, genotype dependency, and potential resistance still necessitate the development of additional therapeutic approaches to be used instead or in combination with DAA.

Recently, the antiviral peptide C5A (in our studies designated as p1) and its cationic derivative p41 have been identified …

Biodegradable Hybrid Nanogels For Combination Chemotherapy, Swapnil Desale

Theses & Dissertations

Combination chemotherapy is commonly used to treat cancer, because such a therapy regimens usually involve sequential administration of multiple drugs and allow targeting different cell signaling pathway. The co-delivery of drug combination at a controlled ratio via the same vehicle is offering the advantages such as spatial-temporal synchronization of drug exposure, synergistic therapeutic effects and suppression of drug resistance. Undoubtedly, there are several molecular and pharmacological factors that determine the effectiveness of drug combinations. A rationally designed drug combination is required since certain drug ratios and the definitive exposure to the targets of interest can only be synergistic while others …

Perioperative Nonopioid Agents For Pain Control In Spinal Surgery., Anna Rivkin, Mark Rivkin

Mark Rivkin

PURPOSE: Commonly used nonopioid analgesic agents that are incorporated into multimodal perioperative pain management protocols in spinal surgery are reviewed. SUMMARY: Spinal procedures constitute perhaps some of most painful surgical interventions, as they often encompass extensive muscle dissection, tissue retraction, and surgical implants, as well as prolonged operative duration. Perioperative nonopioid analgesics frequently used in multimodal protocols include gabapentin, pregabalin, acetaminophen, dexamethasone, ketamine, and nonsteroidal antiinflammatory drugs (NSAIDs). There is evidence to suggest that gabapentin is safe and effective in reducing opioid consumption and pain scores at optimal doses of 600-900 mg orally administered preoperatively. Pregabalin 150-300 mg orally perioperatively …

Phenylephrine Versus Ephedrine: Safest Vasopressor For The Neonate During Caesarean Section, James S. Hale Jr.

Doctoral Projects

One of the most common side effects of spinal anesthesia is the development of hypotension. Data collected has determined that 80% of parturients that undergo spinal anesthesia for this mode of delivery experience hypotension (Chestnut et al., 2014).

Hypotension, if sustained and severe, can lead to fetal hypoxia, neonatal depression or injury, and decreased uteroplacental perfusion. Hypotension can also cause severe health issues for the parturient including apnea, altered level of consciousness, cardiac arrest, and pulmonary aspiration. This systematic review of the literature was conducted to determine whether the administration of phenylephrine or ephedrine was safer for the neonate to …

Overcoming Innate And Acquired Therapy Resistance By Targeting Dna Repair In Human Cancer Cells, Mateusz Rytelewski

Electronic Thesis and Dissertation Repository

Genomic instability and a high mutation rate lead to heterogeneity in human tumors. Mathematical modelling predicts that these characteristics promote acquired resistance to cytotoxic and targeted therapies, by increasing the likelihood that resistant subpopulations exist at the start of treatment (and promoting the accumulation of de novo resistance mutations during treatment). As a result, genome plasticity promotes increased fitness on the population level, but individual tumor cells must nonetheless maintain a level of DNA integrity that allows for continued survival, particularly in the context of DNA-damaging therapy (which DNA repair counteracts). Thus, DNA repair proteins are a source of innate …

Perceptions Of Marijuana Use Among Adolescents, Kofi Amoah, James Baffoe, Katherine Distel, Matt Madden, Jordan Thomas, Insang Yang

Pharmacy and Nursing Student Research and Evidence-Based Medicine Poster Session

Background

The United States federal government has been discouraging use of marijuana for decades. Prior to 1970, the federal regulation of marijuana use was through taxes. In 1970, marijuana use was deemed a criminal offense, and overrode any states that considered it legal. In 2012, Colorado and Washington were the first two states to legalize marijuana for recreational use. A study found adolescent use was 8.68% higher in states allowing medical marijuana and had a significantly lower perception of risks associated with marijuana use (6.94%).

Objectives

To determine if an educational program about the effects of marijuana use can negatively …
