Regulatory Mechanisms Of Leishmania Aquaglyceroporin Aqp1, Mansi Sharma
Regulatory Mechanisms Of Leishmania Aquaglyceroporin Aqp1, Mansi Sharma
FIU Electronic Theses and Dissertations
Pentavalent antimonials [Sb(V)] are the primary drug of choice against all forms of leishmaniasis. Emergence of antimony unresponsiveness is a major issue. There is a dire need of understanding antimony resistance mechanisms in Leishmania. One important mechanism is the down regulation of the trivalent antimony [Sb(III)] (the active form of Sb(V)) uptake system. To date, Leishmania aquaglyceroporin AQP1 is the only reported facilitator of Sb(III). Leishmania do not have promoters. They primarily regulate their genes at post-transcriptional and/or post-translational levels. We reported that mitogen activated protein kinase 2 (MPK2) positively regulated AQP1 stability through the phosphorylation of the threonine …
In Search Of Safety, Negotiating Everyday Forms Of Risk: Sex Work, Criminalization, And Hiv/Aids In The Slums Of Kampala, Serena Cruz
FIU Electronic Theses and Dissertations
This dissertation offers an in-depth descriptive account of how women manage daily risks associated with sex work, criminalization, and HIV/AIDS. Primary data collection took place within two slums in Kampala, Uganda over the course of fourteen months. The emphasis was on ethnographic methodologies involving participant observation and informal and unstructured interviewing. Insights then informed document analysis of international and national policies concerning HIV prevention and treatment strategies in the context of Uganda. The dissertation finds social networks and social capital provide the basis for community formation in the sex trade. It holds that these interpersonal processes are necessary components for …
Investigating The Driving Mechanisms Behind Differences In Bleaching And Disease Susceptibility Between Two Scleractinian Corals, Pseudodiploria Strigosa And Diploria Labyrinthiformis, Zoe A. Pratte
FIU Electronic Theses and Dissertations
Disease and bleaching are two conditions which commonly lead to coral death. Among coral species, susceptibility to disease and bleaching is variable, and Pseudodiploria strigosa tends to be diseased more than Diploria labyrinthiformis, while D. labyrinthiformis bleaches more readily. The focus of this dissertation was to investigate and compare multiple components of these two coral species, and identify how they may relate to disease and bleaching resistance. Compenetnts examined included the surface mucopolysacharide layer (SML) thickness, gene expression, microbial associates, and a white plague aquarium study. The SML thickness decresased with increasing temperature regardless of coral species, indicating that SML …
Overweight/Obesity And Hiv Disease Progression In Hiv+ Adults In Botswana, Sabrina Sales Martinez
Overweight/Obesity And Hiv Disease Progression In Hiv+ Adults In Botswana, Sabrina Sales Martinez
FIU Electronic Theses and Dissertations
Studies indicate that overweight and obesity protect against HIV-disease progression in antiretroviral therapy (ART)-naïve patients. We examined retrospectively the relationship of overweight/obesity with HIV-disease progression in ART-naïve HIV+ adults in Botswana in a case-control study with 18-month follow-up, which included 217 participants, 139 with BMI 18.0-24.9 kg/m2 and 78 with BMI ≥25 kg/m2. Archived plasma samples were used to determine inflammatory markers: leptin and bacterial endotoxin lipopolysaccharide (LPS), and genotype single nucleotide polymorphisms (SNPs) of the Fat Mass and Obesity Associated Gene (FTO).
At baseline, BMI was inversely associated with risk for AIDS-defining conditions (HR=0.218; 95%CI=0.068, 0.701, …
