The AIDS epidemic has tremendously impacted the population of Mozambique. The rate of newly infected young women continues to grow disproportionately which is why consideration of health interventions specific to this population to combat the spread of the disease is critical. The Health Belief Model emphasizes the importance of self efficiency in the process of health related behavioral changes. Previous research has found that low levels of autonomy increase one's risk of contracting HIV/AIDS. This research uses data from a study conducted in 2006 in Mozambique to test whether higher levels of autonomy are associated with the practice of self …

HIV/AIDS is the sixth leading cause of death worldwide and the leading cause of death among women of reproductive age living in low-income countries. Clinicians in industrialized nations monitor the efficacy of antiretroviral drugs and HIV disease progression with the HIV-1 viral load assay, which measures the copy number of HIV-1 RNA in blood. However, viral load assays are not widely available in sub-Saharan Africa and cost between 50-$139 USD per test on average where available. To address this problem, a mixed-methods approach was undertaken to design a novel and inexpensive viral load diagnostic for HIV-1 and to evaluate barriers …

The entire history of HIV-1 is hidden in its ten thousand bases, where information regarding its evolutionary traversal through the human population can only be unlocked with fine-scale sequence analysis. Measurable footprints of mutation and recombination have imparted upon us a wealth of knowledge, from multiple chimpanzee-to-human transmissions to patterns of neutralizing antibody and drug resistance. Extracting maximum understanding from such diverse data can only be accomplished by analyzing the viral population from many angles. This body of work explores two primary aspects of HIV sequence evolution, point mutation and recombination, through cross-sectional (inter-individual) and longitudinal (intra-individual) investigations, respectively. Cross-sectional …

ABSTRACT Manipulation of biological targets using synthetic or naturally occurring organic compounds has been the focal point of medicinal chemistry. The work described herein centers on the synthesis of organic small molecules that are targeted either to cell surface receptors, to the ribosomal catalytic center or to human immunodeficiency virus reverse transcriptase. Bleomycins (BLMs) are a family of naturally occurring glycopeptidic antitumor agents with an inherent selectivity towards cancer cells. DeglycoBLM, which lacks the sugar moiety of bleomycin, has much lower cytotoxicity in cellular assays. A recent study using microbbuble conjugates of BLM and deglycoBLM showed that BLM was able …

Pre-Exposure Prophylaxis (PrEP) is any medical or public health procedure used before exposure to the disease causing agent, its purpose is to prevent, rather than treat or cure a disease. Most commonly, PrEP refers to an experimental HIV-prevention strategy that would use antiretrovirals to protect HIV-negative people from HIV infection. A deterministic mathematical model of HIV transmission is developed to evaluate the public-health impact of oral PrEP interventions, and to compare PrEP effectiveness with respect to different evaluation methods. The effects of demographic, behavioral, and epidemic parameters on the PrEP impact are studied in a multivariate sensitivity analysis. Most of …

Cyanovirin-N (CVN) is a cyanobacterial lectin with potent anti-HIV activity, mediated by binding to the N-linked oligosaccharide moiety of the envelope protein gp120. CVN offers a scaffold to develop multivalent carbohydrate-binding proteins with tunable specificities and affinities. I present here biophysical calculations completed on a monomeric-stabilized mutant of cyanovirin-N, P51G-m4-CVN, in which domain A binding activity is abolished by four mutations; with comparisons made to CVN<super>mutDB</super>, in which domain B binding activity is abolished. Using Monte Carlo calculations and docking simulations, mutations in CVN<super>mutDB</super> were considered singularly, and the mutations E41A/G and T57A were found to impact the affinity towards …

CTB-MPR649-684 is a translational fusion protein consisting of the cholera toxin B subunit (CTB) and the conserved residues 649-684 of gp41 membrane proximal region (MPR). It is a candidate vaccine component aimed at early steps of the HIV-1 infection by blocking viral mucosal transmission. Bacterially produced CTB-MPR was previously shown to induce HIV-1 transcytosis-blocking antibodies in mice and rabbits. However, the induction of high-titer MPR specific antibodies with HIV-1 transcytosis blocking ability remains a challenge as the immuno-dominance of CTB overshadows the response to MPR. X-ray crystallography was used to investigate the structure of CTB-MPR with the goal of identifying …

This document analyzes the use of the Principles of Design within the applied project It’s My Party, a multimedia dance theatre production, as a means to address and overcome the stigmatization of the Human Immunodeficiency Virus (HIV). Through the orchestration of dance, music, props, acting, video, and spoken word, this interdisciplinary work investigates how these production elements synthesize into a transformative theatrical experience for audiences. Outlined in this document is the eight month design process. The process included concept design, assessing, processing, customizing the message, script development, rehearsals, and video production, and concluded with an evening length production. Analyzed through …

Viral protein U (Vpu) is a type-III integral membrane protein encoded by the Human Immunodeficiency Virus-1 (HIV- 1). It is expressed in infected host cells and plays vital roles in down-regulation of CD4 receptors in T cells and also in the budding of virions. But, there remain key structure/function questions regarding the mechanisms by which the Vpu protein contributes to HIV-1 pathogenesis and thus, it makes for an attractive target to study the structural attributes of this protein by elucidating a structural model with X-ray crystallography. This study describes a multi-pronged approach of heterologous over-expression of Vpu. The strategies of …

The HIV-1 pandemic continues to cause millions of new infections and AIDS-related deaths each year, and a majority of these occur in regions of the world with limited access to antiretroviral therapy. Therefore, an HIV-1 vaccine is still desperately needed. The most successful HIV-1 clinical trial to date used a non-replicating canarypox viral vector and protein boosting, yet its modest efficacy left room for improvement. Efforts to derive novel vectors which can be both safe and immunogenic, have spawned a new era of live, viral vectors. One such vaccinia virus vector, NYVAC-KC, was specifically designed to replicate in humans and …
