Characterization Of Kaposi's Sarcoma-Associated Herpesvirus Orf11 As A Possible Dutpase, Christina N. Ramirez

Seton Hall University Dissertations and Theses (ETDs)

A dUTPase is a crucial enzyme that hydrolyzes dUTP to dUMP. This reaction prevents the mutagenic or lethal misincorporation of uracil into DNA. For that reason, the enzyme is required for efficient DNA replication. Previous studies have shown that has ORFl l dUTPase-like motifs and thus may be a dUTPase. Generally, gammaherpesviruses contain six characteristic dUTPase motifs. In particular ORFl 1 and contains motifs 1, 2, 4, 6. While the characteristic motifs of gamroaberpesviruses include motifs 1, 2, 3, 4, 5, and 6, the number of dUTPase-like motifs in ORFl 1 's protein sequence is substantial. Thus, ORFl 1 may …

Analysis Of The Cyc1 Promoter In Candida Albicans, Tomica Blocker

McCabe Thesis Collection

Scientists are considering two factors that may be important in the pathogenesis of C. albicans', it's capability to morph from yeast to hyphal phase, and its differences in colony morphology, cell shape, cell surface and cell permeability. (5) Unfortunately, unlike the bacteria, yeasts do not yet have proven virulence factors. However, science is suggesting that some of the major factors which contribute to the virulence of Candida are its ability to form hyphae, its ability to resist phagocytosis, its ability to adhere to epithelial cell surfaces, its ability to grow well at 37 degrees Celsius, and its ability to secrete …

Moving Forward: Tackling Stigma In A Tanzanian Community, Laura Nyblade, Kerry Macquarrie, Gideon Kwesigabo, Aparna Jain, Lusajo Kajula, Fausta Philip, William Henerico Tibesigwa, Jessie K. Mbwambo

HIV and AIDS

The International Center for Research on Women, the Muhimbili University College of the Health Sciences, the Population Council, and Family Health International conducted an evaluation of a community-based effort to reduce stigma surrounding HIV infections in a peri-urban community in Tanzania. Results presented a mixed, but hopeful, picture for a way forward in tackling stigma at the community level. Tackling stigma requires that the individuals tasked with doing this undergo personal change. Programs can start by focusing stigma-reduction efforts on a smaller, more manageable geographical area and adding specific anti-stigma components to their portfolio of activities. Engaging community opinion leaders …

HIV and AIDS

In Kenya the proportion of eligible HIV-positive children receiving ART treatment is only 11 percent. This study explored and documented possible barriers in the community to accessing pediatric HIV testing and treatment, to guide the development of new interventions to encourage uptake. The study identified barriers such as cost, use of traditional healers, low knowledge of treatment options, attitudinal barriers, stigma, unique treatment issues, and dissatisfaction with available services. Additionally, healthcare workers missed opportunities to provide services and cited numerous service-side challenges. The study recommends prioritizing community awareness, mobile clinics, strengthening capacity of healthcare workers, supporting family-based HIV testing, and …

A Comprehensive Analysis Of The Naturally Occurring Polymorphisms In Hiv-1 Vpr: Potential Impact On Ctl Epitopes., Alagarsamy Srinivasan, Velpandi Ayyavoo, Sundarasamy Mahalingam, Aarthi Kannan, Anne Boyd, Debduti Datta, Vaniambadi S Kalyanaraman, Anthony Cristillo, Ronald G Collman, Nelly Morellet, Bassel E Sawaya, Ramachandran Murali

Department of Microbiology and Immunology Faculty Papers

The enormous genetic variability reported in HIV-1 has posed problems in the treatment of infected individuals. This is evident in the form of HIV-1 resistant to antiviral agents, neutralizing antibodies and cytotoxic T lymphocytes (CTLs) involving multiple viral gene products. Based on this, it has been suggested that a comprehensive analysis of the polymorphisms in HIV proteins is of value for understanding the virus transmission and pathogenesis as well as for the efforts towards developing anti-viral therapeutics and vaccines. This study, for the first time, describes an in-depth analysis of genetic variation in Vpr using information from global HIV-1 isolates …

Has The Hiv Epidemic Peaked?, John Bongaarts, Thomas Buettner, Gerhard Heilig, Francois Pelletier

Poverty, Gender, and Youth

This working paper reviews the highly diverse regional and country patterns of HIV epidemics and discusses possible causes of the geographic variation in epidemic sizes. The main finding of this analysis is that the HIV epidemic reached a major turning point over the past decade. The peak years of HIV incidence rates are past for all regions, and the peaks of prevalence rates are mostly in the past except in Eastern Europe, where it is expected to peak in 2008. But owing in part to the life-prolonging effect of antiretroviral therapy and to sustained population growth, the absolute number of …

Sexual Behavior And Sti/Hiv Status Among Adolescents In Rural Malawi: An Evaluation Of The Effect Of Interview Mode On Reporting, Barbara Mensch, Paul C. Hewett, Richard Gregory, Stephane Helleringer

Poverty, Gender, and Youth

This paper presents the results from an interview-mode experiment conducted by the Population Council with unmarried young women in rural southern Malawi. To collect data on sexual behavior and the dynamics of HIV transmission, respondents were randomly assigned to either an audio computer-assisted self-interview (ACASI) or a conventional face-to-face (FTF) interview. Clear evidence indicates that the mode of interviewing and probing concerning various sexual partnerships affects respondents’ reporting of their sexual activity, yet the results are not always in accordance with expectations. Reporting for “ever had sex” and “sex with a boyfriend” is higher in the FTF mode, whereas, when …

Sexual And Reproductive Health Needs Of Adolescents Perinatally Infected With Hiv In Uganda, Harriet Birungi, John Frank Mugisha, Juliana K. Nyombi, Francis Obare, Humphres Evelia, Hannington Nyinkavu

Reproductive Health

In Uganda, HIV/AIDS treatment, care and support programs are still organized around either adult or pediatric care and fail to adequately address the needs of adolescents, specifically perinatally-infected adolescents. This study, implemented jointly by the Population Council's Frontiers in Reproductive Health (FRONTIERS) program and the AIDS Support Organization (TASO), aimed to better understand the reproductive health and sexuality of this population group, and to identify anxieties or fears they have around entering social stages of adulthood. This study confirms that wide programmatic gaps exist in addressing the sexual and reproductive health needs of young people perinatally infected with HIV who …

Reproductive Health

Between September 2005 and April 2007, FRONTIERS and Alva, a Nicaraguan consulting firm, conducted a situation analysis of the provision and use of contraceptive services in postpartum, postabortion and prevention of mother-to-child transmission of HIV (PMTCT) programs. The project‘s objective was to assess the degree to which contraceptive services were linked to postpartum, postabortion and PMTCT services and if this allowed the programs to meet the contraceptive needs of their clients. The project proposes recommendations for improving the quality of these programs.

Hiv-1 Tat Protein Alter The Tight Junction Integrity And Function Of Retinal Pigment Epithelium: An In Vitro Study., Ling Bai, Zhenping Zhang, Hui Zhang, Xiumei Li, Qiurong Yu, Haotian Lin, Wenhui Yang

Department of Medicine Faculty Papers

BACKGROUND: How HIV-1 enter into the eyes remains obscure. We postulated that HIV-1 Tat protein can alter the expression of specific tight-junction proteins and disturb the blood retinal barrier, and contributes to HIV trafficking into the eyes. This study is to determine the effects of HIV-1 Tat proteins on the barrier function and tight-junction protein expression of retinal pigment epithelial cell (RPE). METHODS: A human RPE cell line (D407) cultured on microporous filter-supports was used. After treating with HIV-1 Tat protein, transepithelial electrical resistance (TER) of confluent RPE cells was measured by epithelial voltmeter. The permeability of the RPE cells …

Direct Inhibition Of Cdk9 Blocks Hiv-1 Replication Without Preventing T Cell Activation In Primary Human Peripheral Blood Lymphocytes, Dominic Salerno, Muneer G Hasham, Renee Marshall Demarest, Judit Garriga, Alexander Y Tsygankov, Xavier Graña

Rowan-Virtua School of Osteopathic Medicine Departmental Research

HIV-1 transcription is essential for the virus replication cycle. HIV-1 Tat is a viral transactivator that strongly stimulates the processivity of RNA polymerase II (RNAPII) via recruitment of the cyclin T1/CDK9 positive transcription elongation factor, which phosphorylates the C-terminal domain (CTD) of RNAPII. Consistently, HIV-1 replication in transformed cells is very sensitive to direct CDK9 inhibition. Thus, CDK9 could be a potential target for anti-HIV-1 therapy. A clearer understanding of the requirements for CDK9 activity in primary human T cells is needed to assess whether the CDK9-dependent step in HIV-1 transcription can be targeted clinically. We have investigated the effects …

A Member Of The Novel Fikk Family Of Plasmodium Falciparum Putative Protein Kinases Exhibits Diacylglycerol Kinase Activity And Is Exported To The Host Erythrocyte, David Floyd Curtis

Electronic Theses and Dissertations

Plasmodium falciparum is one of four species known to cause malaria in humans and is the species that is associated with the most virulent form of the disease. Malaria causes nearly two million deaths each year, many of these occurring among children in under-developed countries of the world. One reason for this is the prevalence of drug resistant strains of malaria that mitigate the efficacy of existing drugs. Hence, the identification of a new generation of pharmacological agents for malaria is extremely urgent. The recent identification of a group of novel protein kinases within the Plasmodium falciparum genome has provided …
