Identification Of Critical Determinants On Ace2 For Sars-Cov Entry And Development Of A Potent Entry Inhibitor, Dong P. Han, Adam Penn-Nicholson, Michael W. Cho

Faculty Scholarship

Severe acute respiratory syndrome (SARS) is caused by a novel coronavirus, SARS-CoV. Virus entry into cells is mediated through interactions between spike (S) glycoprotein and angiotensin-converting enzyme 2 (ACE2). Alanine scanning mutagenesis analysis was performed to identify determinants on ACE2 critical for SARS-CoV infection. Results indicated that charged amino acids between residues 22 and 57 were important, K26 and D30, in particular. Peptides representing various regions of ACE2 critical for virus infection were chemically synthesized and evaluated for antiviral activity. Two peptides (a.a. 22–44 and 22–57) exhibited a modest antiviral activity with IC(50) of about 50 μM and 6 μM, …

Different Public Health Interventions Have Varying Effects, Paula Diehr, Anne B. Newman, Liming Cai, Ann Derleth

UW Biostatistics Working Paper Series

Objective: To compare performance of one-time health interventions to those that change the probability of transitioning from one health state to another. Study Design and Setting: We used multi-state life table methods to estimate the impact of eight types of interventions on several outcomes. Results: In a cohort beginning at age 65, curing all the sick persons at baseline would increase life expectancy by 0.23 years and increase years of healthy life by .54 years. An equal amount of improvement could be obtained with a 12% decrease in the probability of getting sick, a 16% increase in the probability of …

The Vaccine Industry: Does It Need A Shot In The Arm?, Eileen Salinsky, Cole Werble

National Health Policy Forum

This paper broadly examines the scientific, regulatory, and economic factors that contribute to constrained vaccine production capacity, periodic vaccine shortages, and perceptions of inadequate investment in new vaccine product development. It describes the vaccine development and production processes and summarizes how regulatory requirements influence these activities. Market dynamics related to vaccine supply and demand are also explored, including an examination of the industry’s cost structure, potential market size, and purchaser price sensitivity. A broad range of policy interventions designed to address shortcomings of the vaccine market are considered.

Gpnn: Power Studies And Applications Of A Neural Network Method For Detecting Gene-Gene Interactions In Studies Of Human Disease, Alison A. Motsinger, Stephen L. Lee, George Mellick, Marylyn D. Ritchie

Dartmouth Scholarship

The identification and characterization of genes that influence the risk of common, complex multifactorial disease primarily through interactions with other genes and environmental factors remains a statistical and computational challenge in genetic epidemiology. We have previously introduced a genetic programming optimized neural network (GPNN) as a method for optimizing the architecture of a neural network to improve the identification of gene combinations associated with disease risk. The goal of this study was to evaluate the power of GPNN for identifying high-order gene-gene interactions. We were also interested in applying GPNN to a real data analysis in Parkinson's disease.

Environmental Justice And The Role Of Social Capital In An Underserved Urban Community, Lorraine Ann Dillon

Community & Environmental Health Theses & Dissertations

The purpose of this qualitative study was to evaluate a community's beliefs, attitudes, and experiences regarding their neighborhood's environmental health issues and the ways in which individuals utilize social capital (the degree to which a community collaborates and cooperates) to improve their environmental health. Research correlating social capital with health status shows that the higher the level of social capital in a community, the better the health. An understanding of why some groups exhibit more social capital than others is important in improving the public health system. The study was accomplished by comparing a convenience sample of two specific groups …

Shifting Support For Inequitable Gender Norms Among Young Indian Men To Reduce Hiv Risk And Partner Violence, Ravi K. Verma, Vaishali Sharma Mahendra, Julie Pulerwitz, Sujata Khandekar, Gary Barker, P. Fulpagare, S.K. Singh

HIV and AIDS

India accounts for the second largest population of people living with HIV/AIDS (5.1 million), and almost half of new infections occur in young men below age 30. While there are multiple factors influencing young men’s HIV risk in India, one that is receiving increasing attention is early socialization about masculinity. Young men in India mature and develop in a male-dominated context, having little contact with female peers and virtually no sex education. In this context, most boys develop a sense of masculinity characterized by male dominance in the sexual arena and other areas. Although there is increasing awareness of the …

Science-Based Organic Farming 2006: Toward Local And Secure Food Systems, Charles A. Francis, Katja Koehler-Cole, Twyla Hansen, Peter Skelton

Publications from the Center for Applied Rural Innovation (CARI)

Organic farming includes growing food and fiber—animals, agronomic crops, horticultural fruits and vegetables, related products—as one dynamic and rapidly evolving component of our complex U.S. food system. Even as more farmers are moving toward organic certification and participation in an environmentally sound and economically lucrative market, questions arise about the long-term social impacts and sustainability of a set of practices that has gone from a movement to an industry. Consolidations in the organic trade have brought multinational corporations to the table, as they have observed a grassroots activity that has grown by 20% per year for the past two decades, …

Norovirus Classification And Proposed Strain Nomenclature, Du-Ping Zheng, Tamie Ando, Rebecca L. Fankhauser, R. Suzanne Beard, Roger I. Glass, Stephan S. Monroe

United States Public Health Resources

Without a virus culture system, genetic analysis becomes the principal method to classify norovirus (NoV) strains. Currently, classification of NoV strains beneath the species level has been based on sequences from different regions of the viral genome. As a result, the phylogenetic insights of some virus were not appropriately interpreted, and no consensus has been reached to establish a uniform classification scheme. To provide a consistent and reliable scientific basis for classifying NoVs, we analyzed the amino acid sequences for the major capsid protein of 164 NoV strains by first using an alignment based on the predicted 3D structures. A …

Agroterrorism—Why We’Re Not Ready: A Look At The Role Of Law Enforcement, Alberto R. Gonzales, Regina B. Schofield, Glenn R. Schmitt

United States Public Health Resources

Terrorists seeking to strike a blow at the U.S. economy need look no further than the Nation’s heartland for a “soft” target. An agroterrorist attack could dramatically impact many aspects of American life, including local law enforcement, which— especially in rural areas—is financially and strategically unprepared to respond.
Agricultural experts say that today they are most concerned about the intentional introduction of foot-and-mouth disease (FMD) into the food supply. Twenty times more infectious than smallpox, FMD causes painful blisters on the tongues, hooves, and teats of cloven-hoofed animals (like cows, pigs, goats, and deer), rendering them unable to walk, be …

Allen, Heiko Jessen, Eric S. Rosenberg, Mary Carrington, Bruce D. Walker

United States Public Health Resources

Background

Very little is known about the immunodominance patterns of HIV-1-specific T cell responses during primary HIV-1 infection and the reasons for human lymphocyte antigen (HLA) modulation of disease progression.

Methods and Findings

In a cohort of 104 individuals with primary HIV-1 infection, we demonstrate that a subset of CD8⁺ T cell epitopes within HIV-1 are consistently targeted early after infection, while other epitopes subsequently targeted through the same HLA class I alleles are rarely recognized. Certain HLA alleles consistently contributed more than others to the total virus-specific CD8⁺ T cell response during primary infection, and also reduced …

Temperament In Context: Infant Temperament Moderates The Relationship Between Perceived Neighborhood Quality And Behavior Problems, Craig R. Colder, Liliana J. Lengua, Paula J. Fite, Joshua A. Mott, Nicole R. Bush

United States Public Health Resources

Hypotheses that positive affect and fear in infancy moderate later relationships between neighborhood quality and behavior problems were examined in a sample of children from the National Longitudinal Survey of Youth. Results suggested that poor neighborhood quality was associated with antisocial behavior at age 6 for children who in infancy were characterized by either high positive affect and low fear or by low positive affect and high fear. Depression/anxiety increased from age 6 to age 12 for children in poor quality neighborhoods who were characterized in infancy by low positive affect. A combination of low fear and high positive affect …

Identification Of An Epithelial-Specific Enhancer Regulating Esx Expression, Richard M. Neve, Hema Parmar, Cliff Amend, Chira Chen, Angie Rizzino, Christopher C. Benz

United States Public Health Resources

The Ets transcription factor, ESX, exhibits a unique pattern of epithelial-restricted expression and transactivates genes involved in epithelial differentiation and cancer. The aim of this study was to determine the underlying genetic basis for epithelial-specific expression of ESX. We have identified a 30bp ESX enhancer sequence (EES) approximately 3 kb upstream of the proximal promoter. This region displays enhancer activity in an epithelial-specific manner and deletion of this region abrogates ESX gene transcription. An EES binding protein complex (EBC) was identified through electrophoretic mobility shift assays whose degree of EES binding correlated well with endogenous ESX levels in …

Sulfation Of Tibolone Metabolites By Human Postmenopausal Liver And Small Intestinal Sulfotransferases (Sults), Min Wang, Christopher C. Ebmeier, John R. Olin, Robert J. Anderson

United States Public Health Resources

Sulfation is a major pathway in humans for the biotransformation of steroid hormones and structurally related therapeutic agents. Tibolone is a synthetic steroid used for the treatment for climacteric symptoms and postmenopausal osteoporosis. Sulfation inactivates the hydroxylated metabolites, 3α-hydroxytibolone (3α-OH-tibolone) and 3β-hydroxytibolone (3β-OH-tibolone), and contributes to the regulation of tissue responses to tibolone. We detected SULT1A1, SULT1A3, SULT1E1 and SULT2A1 mRNA expression by RT-PCR in postmenopausal liver and small intestine. Liver pool (n = 5) SULT activities measured with tibolone substrates reflected COS-1 expressed SULT2A1 and SULT1E1 activities. Liver SULT2A1 activity (1.8±0.3 units/mg protein, n = 8, mean ± SEM), …

Expanding Pediatric Access To Antiretroviral Therapy In South Africa, Desiree Michaels, Brian Eley, Lewis Ndhlovu, Naomi Rutenberg, Hena Khan

HIV and AIDS

In sub-Saharan Africa, AIDS has become one of the leading causes of death among children under the age of five years. Yet, despite increased availability of antiretroviral therapy (ART), children have been largely ignored or excluded from treatment initiatives. While efforts to get more children on treatment are increasing, important information is lacking to guide program and policy implementation. To address these gaps, the Horizons Program and the University of Cape Town conducted a rapid situational analysis in 2005 of pediatric HIV treatment sites in South Africa. In 2003, the South African government approved a plan for a national HIV …

Female Genital Mutilation In Kenya: Evidence Links Health Workers To Fgm, Population Council, Gtz

Reproductive Health

Female genital mutilation (FGM) is a traditional practice that affects women and girls in several African countries. It is practiced in a variety of ways, classified by WHO into four broad types all found in Kenya. In some communities it is associated with passage into maturity; in others, it is considered a symbol of ethnic identity, a religious obligation, or a necessary prerequisite for marriage, either through symbolizing attainment of womanhood or as a means of preserving and demonstrating virginity. FGM is considered a harmful traditional practice because it may be associated with a variety of short- and long-term health …
