Agricultural Pesticide Use And Risk Of T(14;18)-Defined Subtypes Of Non-Hodgkin Lymphoma, Brian C.-H. Chiu, Bhavana J. Dave, Aaron Blair, Susan M. Gapstur, Shelia Hoar Zahm, Dennis D. Weisenburger

Public Health Resources

Pesticides have been specifically associated with the t(14;18)(q32;q21) chromosomal translocation. To investigate whether the association between pesticides and risk of non-Hodgkin lymphoma (NHL) differs for molecular subtypes of NHL defined by t(14; 18) status, we obtained 175 tumor blocks from case subjects in a population-based case-control study conducted in Nebraska between 1983 and 1986. The t(14;18) was determined by interphase fluorescence in situ hybridization in 172 of 175 tumor blocks. We compared exposures to insecticides, herbicides, fungicides, and fumigants in 65 t(14;18)-positive and 107 t(14;18)-negative case subjects with those among 1432 control subjects. Multivariate polytomous logistic regression was used to …

Evaluation Of Serum Immunoglobulins Among Individuals Living Near Six Superfund Sites, Dhelia M. Williamson, Mary C. White, Charles Poole, David Kleinbaum, Robert Vogt, Kari North

Public Health Resources

Residents living in communities near Superfund sites have expressed concern that releases from these facilities affect their health, including adverse effects on their immune systems. We used data from six cross-sectional studies to evaluate whether people who live near several Superfund sites are more likely to have individual immunoglobulin test results (IgA, IgG, and IgM) below or above the reference range than those who live in comparison areas with no Superfund site. Study participants consisted of target-area residents who lived close to a Superfund site and comparison area residents who were not located near any Superfund or hazardous waste sites. …

Geographic Factors Contributing To A High Seroprevalence Of West Nile Virus-Specific Antibodies In Humans Following An Epidemic, Beth K. Schweitzer, Wayne L. Kramer, Anthony R. Sambol, Jane L. Meza, Steven H. Hinrichs, Peter C. Iwen

Public Health Resources

Sera of 624 blood donors were evaluated to determine seroprevalence of West Nile virus (WNV) antibodies following the 2003 WNV epidemic in Nebraska. Geographic factors contributing to differences in WNV seropositivity were evaluated. The overall prevalence of WNV in Nebraska was higher than reported previously in other U.S. locations (9.5% WNV immunoglobulin G seroprevalence rate), with the highest prevalence identified in the western part of the state (19.7%), followed by the central (13.8%) and the eastern (4.2%) parts. Regions of the state with the highest WNV-positive mosquito rates correlated with the highest human WNV seroprevalence rates. The results showed that …

The Frustrations Of Families: Henry Lynch, Heredity, And Cancer Control, 1962–1975, David Cantor

Public Health Resources

When Henry T Lynch thought that he had discovered the existence of hereditary cancers among Nebraskan families in the 1960s, his hope was that it would lead to more effective means of cancer control. Lynch argued that the identification of such cancers offered tremendous opportunities for improving detection and treatment. If cancer ran in families, he claimed, the discovery of a hereditary cancer in one family member should be an alert to the possibility of cancer in others, and so prompt careful scrutiny for any signs that might indicate the presence of the disease in ‘‘healthy’’ individuals. Lynch hoped that …

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

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 …

Background: The second-generation hepatitis C virus (HCV) enzyme immunoassay (EIA 2), an antibody-detection test, has high sensitivity and is one of the recommended screening tests for detecting HCV infection in the United States. However, its sensitivity among oncology patients is unknown.
Objective: Assess the EIA 2 sensitivity among a group of oncology patients at a Nebraska clinic where an HCV outbreak occurred during 2000–2001 using nucleic acid testing (NAT) and recombinant immunoblot assay (RIBA) as the gold standards.
Study design: Serum specimens were collected from patients 16 months after transmission had stopped. We tested the specimens using EIA 2 (Abbott …

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

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

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), …

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

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 …

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 …

West Nile Virus Quantification In Feces Of Experimentally Infected American And Fish Crows, Aaron Kipp, Jennifer Lehman, Richard Bowen, Patricia Fox, Michael Stephens, Kaci Klenk, Nicholas Komar, Michel Bunning

Public Health Resources

To better understand the potential environmental health risk presented by West Nile virus (WNV)- contaminated feces, we quantified the amount of WNV present in the feces of experimentally infected American crows (Corvus brachyrhynchos) and fish crows (Corvus ossifragus). Peak fecal titers ranged from 10^3.5 to 10^8.8 plaque-forming units (PFU)/g for 10 American crows and from 10^2.3 to 10^6.4 PFU/g for 10 fish crows. The presence of infectious WNV in bird feces indicates a potential for direct transmission of WNV. Thus, handlers of sick or dead birds should take appropriate precautions to avoid …

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

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 …
