Here we report the results of an investigation into the possibility that one mechanism responsible for the establishment of persistent human immunodeficiency virus infection is an early regulatory T (T_reg) cell response that blunts virus- specific responses. Using the simian immunodeficiency virus (SIV)–infected rhesus macaque model, we show that, indeed, viral replication and immune activation in lymphatic tissue drive a premature immunosuppressive response, with dramatic increases in the frequencies of CD4⁺CD25⁺FOXP3⁺ Treg cells, transforming growth factor–β1⁺ cells, interleukin–10+ cells, and indoleamine 2,3-dioxygenase+CD3⁺ cells.When we compared SIV infection with rhesus cytomegalovirus (RhCMV) …

Religious And Denominational Problems In Nevada, Noel Tiano

Social Health of Nevada Reports

Ever since the earliest civilizations, humans have sought to make sense of their relationship with other beings, the universe, and the unknown through religious beliefs and practices. Shamans and healers interpreted phenomena for their followers, nuns cared for the sick and dying, ministers spearheaded anti-slavery movements, and religious activists joined campaigns for prison reform, worked for charitable organizations, and promoted novel educational institutions. Mother Theresa, Gandhi, Martin Luther King, Jr., the Dalai Lama and other world leaders with strong religious convictions have shown us what love in action means

Suicide Trends And Prevention In Nevada, Matt Wray

Social Health of Nevada Reports

Suicide has been around for as long as human society and it continues to challenge our collective wisdom. Consider this data provided by the National Institute of Medicine:

• Each year about one million people commit suicide worldwide.
• Every year some 30,000 Americans end their lives by suicide, and approximately 650,000 people receive emergency treatment after attempting suicide.
• Every 41 seconds someone in the U.S. attempts suicide; every 16.7 minutes, someone completes suicide; and every day over 85 people die by suicide.
• Suicide is the eighth leading cause of death in the U.S. and the third leading cause of death among …

Problem Gambling And Treatment In Nevada, Bo Bernhard

Social Health of Nevada Reports

For many years, it was moral experts, rather than medical and academic ones, who told us who gambled “too much.” Speaking from pulpits rather than podiums, church leaders informed us that gambling was uniquely subversive of the American way of life, for its something-for-nothing promise threatened to undermine the popular ethic of honest toil and gradual accumulation of goods. Samuel Hopkins, in an 1835 sermon on “The Evils of Gambling,” captured this sensibility: “Let the gambler know that he is watched, and marked; and that . . . he is loathed. Let the man who dares to furnish a resort …

Teen Sexuality And Pregnancy In Nevada, Marta Meana, Lea Thaler

Social Health of Nevada Reports

The United States has the highest rate of teen pregnancy in the fully industrialized world. While the rates have been declining in the last 15 years, it remains a source of concern that

• 34% of teenage girls in the U.S. are becoming pregnant at least once before the age of 20.
• The teen pregnancy in the U.S. rate is ten times that of Japan, four times those of France and Germany, and nearly twice that of Great Britain.

Diseases Prevalence And Behavioral Choices In Nevada, Mary Guinan, Chad L. Cross, Lawrence Sands

Social Health of Nevada Reports

Determining the health of a state population is a complex task. It involves knowing at least the prevalence of various diseases and conditions as well as the leading causes of death and disability compared to a national mean or median. The World Health Organization defines health as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” Since health is affected by numerous social, economic, environmental, and cultural factors, these factors must also be considered when examining the health status of a population. All attempts to rank states in health are limited …

Health Care Access And Insurance Availability In Nevada, Charles B. Moseley, Michelle Sotero

Social Health of Nevada Reports

According to the Institute of Medicine (IOM),

• Approximately 18,000 Americans die prematurely every year, solely because they lack health insurance coverage (Institute of Medicine, 2004).
• The IOM estimates that the aggregate cost of increased morbidity and mortality due to un-insurance in the U.S. is between $65 billion and $130 billion per year.
• Costs to the health care system can be measured conservatively in terms of the value of uncompensated care provided to the uninsured, estimated at almost $35 billion in 2001, of which $24 billion was provided by hospitals.

Access to medical care is not a constitutional right in the …

An Exploratory Study Of Constructions Of Masculinity, Sexuality And Hiv/Aids In Namibia, Southern Africa, Jill Brown, James Sorrell, Marcela Raffaelli

Department of Psychology: Faculty Publications

The goal of the current study was to explore notions of masculinity and their linkages to HIV/AIDS among Owambo men and women in Namibia, where an estimated one-fifth of 15–49 year-olds have acquired HIV. Thirteen open-ended interviews and three focus groups were conducted with 50 male and female participants aged 19–50 in rural and urban Namibia. Qualitative analysis revealed six central themes: the evolving meanings of masculinity, power dynamics between men and women, women as active agents, the tension between formal and informal education and HIV transmission, alcohol and masculinity, and the blending of masculinity and explanations of HIV and …

A Human T-Cell Lymphotropic Virus Type 1 Enhancer Of Myc Transforming Potential Stabilizes Myc-Tip60 Transcriptional Interactions, Soumya Awasthi, Anima Sharma, Kasuen Wong, Junyu Zhang, Elizabeth F. Matlock, Lowery Rogers, Pamela Motloch, Shigeki Takemoto, Hirokuni Taguchi, Michael D. Cole

Dartmouth Scholarship

The human T-cell lymphotropic virus type 1 (HTLV-1) infects and transforms CD4+ lymphocytes and causes adult T-cell leukemia/lymphoma (ATLL), an aggressive lymphoproliferative disease that is often fatal. Here, we demonstrate that the HTLV-1 pX splice-variant p30II markedly enhances the transforming potential of Myc and transcriptionally activates the human cyclin D2 promoter, dependent upon its conserved Myc-responsive E-box enhancer elements, which are associated with increased S-phase entry and multinucleation. Enhancement of c-Myc transforming activity by HTLV-1 p30II is dependent upon the transcriptional coactivators, transforming transcriptional activator protein/p434 and TIP60, and it requires TIP60 histone acetyltransferase (HAT) activity and correlates with the …

Weast Nile Virus Serosurveillance In Iowa White-Tailed Deer (1999-2003), Julian Santatella, Robert Mclean, Jeffrey S. Hall, James S. Gill, Richard A. Bowen, Harlo H. Hadow, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

Sera from white-tailed deer (Odocoileus virginianus) were collected in Iowa during the winter months (1999-2003), 2 years before and after West Nile virus (WNV) was first reported in Iowa (2001), and were analyzed for antibodies to WNV. Samples from 1999 to 2001 were antibody negalive by blocking enzyme-linikedI immunosorbent assay (bELISA) and plaque reduction neutralization test (PRNT₉₀). Prevalence derived from bELISA (2002, 12.7%; 2003. 11.2%) and WNV PRNT₉₀ (2002,7.9%; 2003, 8.5%) assays were similar. All sanlples were negative for antibodies against St. Louis encephalitis virus as determined by PRNT₉₀. Antibodies to flaviviruses were …

Hiv/Aids And Condom Usage: Factors That Contribute To African American Women's Vulnerability To Hiv Infection, Monica P. Washington

Sociology & Criminal Justice Theses & Dissertations

HIV/AIDS poses an enormous health threat to African Americans, specifically African American women. According to the Center for Disease Control "1 in 160 African American women are believed to be infected with HIV (Center for Disease Control 1999:1). In 2000, although African American women only represented 12% of the female population, they accounted for 64% of HIV cases reported among women (The White House 2000; National Institute of Allergy and Infectious Diseases 2004).

This study examined HIV/AIDS and African American women and attempted to answer the question: Why are African American women not consistently using condoms to protect themselves against …

Expression Of Hepatitis C Viral Non-Structural 3 Antigen In Transgenic Chloroplasts, Anubhuti Bhati

Electronic Theses and Dissertations

Hepatitis C viral infection is the major cause of acute hepatitis and chronic liver disease and remains the leading cause of liver transplants (NIH). An estimated 180 million people are infected globally (WHO). There is no vaccine available to prevent hepatitis C. The treatment with antiviral drugs is expensive, accompanied with various side effects and is limited only to those at risk of developing advanced liver disease. The treatment is also effective in only about 30% to 50% of treated patients and still a high percentage of patients are resistant to therapy. Therefore, there is an urgent need for the …

Expression Of Cholera Toxin B Subunit-Rotavirus Nsp4 Enterotoxin Fusion Protein In Transgenic Chloroplasts, Anila Kalluri

Electronic Theses and Dissertations

Rotavirus, the major cause of life-threatening infantile gastroenteritis, is a member of the Reoviridae family and is considered to be the single most important cause of virus-based severe diarrheal illness in infants and young children particularly 6 months to 2 years of age in industrialized and developing countries. Infection in infants and young children is often accompanied by severe life threatening diarrhea, most commonly following primary infection. Diarrhea is the major cause of death among children around the world. Responsible for 4 to 6 million deaths per year according to the World Health Organization (WHO), diarrhea is especially dangerous for …

Reducing The Transmission Of Hiv And Sexually Transmitted Infections In A Mining Community: Findings From The Carletonville Mothusimpilo Intervention Project: 1998 To 2001, Lewis Ndhlovu, Catherine Searle, Johannes Van Dam, Yodwa Mzaidume, Bareng Rasego, Solly Moema

HIV and AIDS

The Horizons program, in collaboration with the Center for Scientific and Industrial Research, the South African Institute for Medical Research, and the London School of Economics, conducted an intervention study in the mining town of Carletonville, South Africa to examine the social determinants of the HIV epidemic, and to assess the impact of a targeted program of HIV and STI prevention and service delivery. The project did not reduce STI prevalence or HIV prevalence, as changing sexual behavior is far more complex than educating individuals about HIV. The report recommends interventions to support behavioral change education, STI treatment, the role …

Programming For Hiv Prevention In South African Schools: A Report On Program Implementation, Priscilla Reddy, Shegs James, Ann P. Mccauley

HIV and AIDS

An evaluation study conducted in KwaZulu Natal, South Africa, provides important insights into whether learners who participated in a fact-based, interactive course had more knowledge about HIV risks, prevention, and care practices; more positive attitudes toward prevention practices and people living with HIV and AIDS; and a higher prevalence of reported safe behaviors than comparable learners who did not participate in the course. Results show that the Life Skills Grade 9 Curriculum had a positive impact of students’ knowledge of HIV/AIDS, attitudes about abstinence, and intention to use condoms. There was, however, no evidence of increased adoption of such protective …

Mouse Cytomegalovirus M33 Is Necessary And Sufficient In Virus-Induced Vascular Smooth Muscle Cell Migration, Ryan Melnychuk, Patsy Smith, Craig N. Kreklywich, Franziska Ruchti, Jennifer Totonchy, Laurel Hall, Lambert Loh, Jay A. Nelson, Susan L. Orloff, Daniel N. Streblow

Pharmacy Faculty Articles and Research

Mouse cytomegalovirus (MCMV) encodes two potential seven-transmembrane-spanning proteins with homologies to cellular chemokine receptors, M33 and M78. While these virus-encoded chemokine receptors are necessary for the in vivo pathogenesis of MCMV, the function of these proteins is unknown. Since vascular smooth muscle cell (SMC) migration is of critical importance for the development of atherosclerosis and other vascular diseases, the ability of M33 to promote SMC motility was assessed. Similar to human CMV, MCMV induced the migration of mouse aortic SMCs but not mouse fibroblasts. To demonstrate whether M33 was required for MCMV-induced SMC migration, we employed interfering-RNA technology to specifically …

Understanding The Hiv/Sti Risks And Prevention Needs Of Men Who Have Sex With Men In Nairobi, Kenya, Washington Onyango-Ouma, Harriet Birungi, Scott Geibel

HIV and AIDS

Despite increasing awareness of the role men who have sex with men (MSM) can play in the dynamics of HIV transmission in Africa, research on MSM in Kenya has been limited. In response to this gap, researchers from the Institute of African Studies at the University of Nairobi and the Horizons and FRONTIERS programs of the Population Council undertook a study of MSM in Nairobi. The overall goals of the study were to understand the extent to which MSM are at risk of HIV and other STIs, identify the factors associated with risk behaviors, and identify MSM sexual health needs …

Potential Roles Of Follicular Dendritic Cell–Associated Osteopontin In Lymphoid Follicle Pathology And Repair And In B Cell Regulation In Hiv-1 And Siv Infection, Qingsheng Li, Jeffrey D. Lifson, Lijie Duan, Timothy Schacker, Cavan Reilly, John V. Carlis, Jacob D. Estes, Ashley T. Haase

Qingsheng Li Publications

Osteopontin is a multifunctional protein with known roles in bone remodeling, wound healing, and normal and pathological immune responses. We showed in microarray studies that osteopontin gene expression is increased in human immunodeficiency virus type 1 (HIV-1)–infected lymphatic tissues after treatment, and we undertook mapping experiments to study osteopontin’s possible functions in this context. We discovered species-specific colocalization of osteopontin with the follicular dendritic cell (FDC) network in lymphatic tissues in HIV-1 and simian immunodeficiency virus infections, and we found that changes in FDC-associated osteopontin covary with changes in lymphoid follicles during acute and late stages of infection and in …

T-Cell Responses To The M3 Immune Evasion Protein Of Murid Gammaherpesvirus 68 Are Partially Protective And Induced With Lytic Antigen Kinetics, Joshua J. Obar, Douglas C. Donovan, Sarah G. Crist, Ondine Silvia, James P. Stewart, Edward J. Usherwood

Dartmouth Scholarship

DNA vaccination with the M3 gene, encoding an immune evasion molecule expressed during both the acute lytic and persistent phases of murid gammaherpesvirus 68 infection, yielded a significantly lower titer of virus in the lung than controls. The protection seen was dependent on T cells, and we mapped an epitope recognized by CD8 T cells. The immune response to this epitope follows the same kinetics as lytic cycle antigens, despite the fact that this gene is expressed in both lytic and persistent stages of infection. This has important implications for our understanding of T-cell responses to putative latency-associated gammaherpesvirus proteins …

The Population Council and its research partners have been addressing several key questions about prevention of mother-to-child HIV transmission (PMTCT) services and how well they function in field settings. The World Health Organization asked the Population Council to provide a review of field experiences regarding the integration of family planning and PMTCT services. This report provides conclusions and recommendations as input into a WHO/UNFPA-sponsored consultative meeting on "The linkages between reproductive health and HIV/AIDS: Family planning and prevention of mother-to-child transmission."

Maximizing Resources To Meet Client Needs: Evaluation Of A Comprehensive Hiv/Aids Care And Support Model In India, Yrg Care, Horizons Program, International Hiv/Aids Alliance

HIV and AIDS

To examine the benefits and feasibility of service delivery, the Horizons program and the International HIV/AIDS Alliance undertook a multifaceted operations research study of YRG CARE, a nongovernmental organization which offers services to PLHA in southern India. Data from this study suggest that comprehensive care and support services have had a positive impact on perceived quality of life, serostatus disclosure, number of illness episodes, and household expenditures for those patients who participated in the study. The results of this component of the study support the value of scaling-up the YRG CARE service model to other NGOs in India to expand …
