Implications Of Human Umbilical Cord Blood Cells: An Immunotherapeutic Strategy For Alzheimer's Disease, Donna Darlington

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Alzheimer's disease (AD) is the most common progressive age related dementia and the fourth major cause of mortality in the elderly in the United States. AD is pathologically characterized by deposition of amyloid beta (Aβ) plaques in the brain parenchyma and neurofibrillary tangles (NFTs) within the neuronal soma. While pharmacological targets have been discovered, current strategies for the symptomatic or disease-modifying treatment of AD do not significantly slow or halt the underlying pathological progression of the disease. Consequently, more effective treatment is needed. One possibility for amelioration is using human umbilical cord blood cell (HUCBC) therapy. HUCBCs comprise a …

Pathogenic Mechanisms And Signaling Pathways In Plasmodium Falciparum, Jennifer L. Sedillo

USF Tampa Graduate Theses and Dissertations

Plasmodium falciparum is a human intracellular parasite that is the causative agent of a deadly form of malaria. This species alone is responsible for 200 million cases of malaria annually resulting in over 1 million deaths worldwide. The excessive mortality due to P. falciparum infection is due to its ability to cause severe pathogenesis through hyperparasitemia and cytoadherence defined as the ability of infected red blood cells to adhere to host vasculature. Cytoadherence is mediated through the export of parasite proteins to the surface of the infected red blood cell (RBC). Exported proteins have been identified but the pathway for …

Molecular Evidence For Vector Implication Of Onchocerca Lupi In Los Angeles County, Ca, Shanna June Bolcen

USF Tampa Graduate Theses and Dissertations

Onchocerca is a genus of roundworm most commonly associated with the human infection onchocerciasis, or river blindness. While typically a zoonotic infection of ungulate populations, canine cases (Onchocerca lupi) have been identified in the United States and Greece. In 2012, Los Angeles County, Veterinary Public Health Program identified 3 cases of Onchocerca spp. infections in domestic canines. Samples from the ensuing blackfly collections were sent to the Global Health Infectious Disease Research Unnasch Laboratory for parasite isolation and vector species identification. Species-specific primers were designed and optimized for O. lupi using a non- specific cytochrome oxidase (COI) gene target (689bp) …
