Sodium Tanshinone Iia Sulfonate Mediates Electron Transfer Reaction In Rat Heart Mitochondria, Guangyin Zhou, Wen Jiang, Yan Zhao, Guangén Ma, Wenjuan Xin, Junjie Yin, Baolu Zhao

United States Public Health Resources

In this paper, an electron transfer reaction mediated by sodium tanshinone IIA sulfonate (STS) was studied in rat heart mitochondria. It was found that STS could stimulate mitochondrial NADH oxidation dose-dependently and partly restore NADH oxidation in the presence of respiratory inhibitor (rotenone or antimycin A or KCN). It was likely that STS could accept electrons from complex I similar to ferricyanide and could be converted to its semiquinone form that could then reduce oxygen molecule. The data also showed that cytochrome c (Cyt c) could be reduced by STS in the presence of KCN, or STS could transfer the …

A Preliminary Linkage Map Of The Hard Tick, Ixodes Scapularis, A. J. Ullmann, J. Piesman, M. C. Dolan, W. C. Black Iv

United States Public Health Resources

Blackwell Publishing Ltd. A linkage map of the Ixodes scapularis genome was constructed, based upon segregation amongst 127 loci. These included 84 random amplified polymorphic DNA (RAPD) markers, 32 Sequence-Tagged RAPD (STAR) markers, 5 cDNAs, and 5 microsatellites in 232 F₁ intercross progeny from a single, field-collected P₁ female. A preliminary linkage map of 616 cM was generated across 14 linkage groups with one marker every 10.8 cM. Assuming a genome size of ~ 10 ⁹ bp, the relationship of physical to genetic distance was found to be ~ 300 kb/cM in the I. scapularis genome.

Absence Of Interferon-Γ–Inducible Gene Igtp Does Not Significantly Alter The Development Of Chagasic Cardiomyopathy In Mice Infected With Trypanosoma Cruzi (Brazil Strain), A. P. De Souza, B. Tang, H. B. Tanowitz, S. M. Factor, V. Shtutin, J. Shirani, G. A. Taylor, L. M. Weiss, L. A. Jelicks

United States Public Health Resources

Interferon-γ (IFN-γ) contributes to host resistance during acute infection with Trypanosoma cruzi, the causative agent of Chagas’ disease. Inducibly expressed guanosine triphosphatase (IGTP), a 48-kDa guanosine triphosphatase (GTPase), is a member of a family of GTPase proteins inducibly expressed by IFN-γ. The expression pattern of IGTP suggests that it may mediate IFN-γ–induced responses in a variety of cell types. IGTP has been demonstrated to be important for control of Toxoplasma gondii infection but not for resistance against Listeria monocytogenes. We evaluated the role of IGTP in development of chronic chagasic cardiomyopathy in IGTP null mice and C57X129sv (wild …

Overall, the systems correctly …

Estimated Risk Of Transmission Of The West Nile Virus Through Blood Transfusion In The Us, 2002, Brad J. Biggerstaff, Lyle R. Petersen

United States Public Health Resources

BACKGROUND: The West Nile virus (WNV) epidemic in 2002 in the US saw over 3300 reported human cases of WNV disease, with over 2300 reported cases of WNV encephalitis and meningitis. The first documented cases of transfusion transmission of WNV through voluntary blood donation also occurred.

STUDY DESIGN AND METHODS: Case onset dates from the 2002 WNV epidemic in the US were used to estimate the risk of transfusion-associated transmission with statistical resampling. An easily computed approximating formula for the mean risk was derived. Estimates were computed for six high-incidence states and metropolitan areas.

RESULTS: Mean and …

Incidence Of Ovarian Cancer By Race And Ethnicity In The United States, 1992–1997, Marc T. Goodman, Holly L. Howe, Ko Hui Tung, Joellyn Hotes, Barry A. Miller, Steven S. Coughlin, Vivien W. Chen

United States Public Health Resources

Ovarian cancer is the fifth most common cancer among U.S. women.¹ An estimated 23,400 new cases were expected to be diagnosed in the U.S. in 2001. As is the case for breast and endometrial cancers, ovarian cancer is more common among women in northern and central Europe, and North America compared with Africa, South America, and Asia.² In the U.S., substantial racial and ethnic variations also are observed in the incidence of ovarian cancer. rates reportedly are highest among non-Hispanic white and American Indian women, and are lower among Hispanic, Native Hawaiian, and Asian women.³ Among white …

Inhibition Of Markers Of Hepatic Stellate Cell Activation By The Hormone Relaxin, Robert G. Bennett, Kusum K. Kharbanda, Dean J. Tuma

United States Public Health Resources

Hepatic fibrois results from excess extracellular matrix produced primarily by hepatic stellate cells (HSC). In response to injury, HSC differentiate to a myofibroblastic phenotype expressing smooth muscle actin and fibrillar collagens. Relaxin is a polypeptide hormone shown to have antifibrotic effects in fibrosis models. In this study, activated HSC from rat liver were treated with relaxin to determine if relaxin can reverse markers of HSC activation. Relaxin treatment resulted in a decrease in the expression of smooth muscle actin, but had no effect on cell proliferation rate. The levels of total collagen and type I collagen were reduced, while the …

Ethanol Consumption Decreases The Synthesis Of The Mannose 6-Phosphatelinsulin-Like Growth Factor Ii Receptor But Does Not Decrease Its Messenger Rna, James Haorah, Richard Macdonald, Julie A. Stoner, Terrence M. Donohue, Jr.

United States Public Health Resources

The mannose 6-phosphatelinsulin-like growth factor I1 receptor (M6P/IGF-IIR) is a protein that facilitates the transport of acid hydrolases into the lysosome. We have shown that chronic ethanol consumption lowers the M6P/IGF-IIR content in rat hepatocytes. Here, we determined the steady-state level of mRNA encoding M6P/IGF-IIR, as well as the rate of receptor synthesis, to ascertain whether the ethanol-elicited reduction in receptor protein content is related to changes in either or both of these parameters. Rats were pair-fed the normal carbohydrate (NC) or low carbohydrate high-fat (LC) liquid diets containing either ethanol or isocaloric maltose-dextrin for 7-8 weeks. RNA was isolated …

Impaired Receptor-Mediated Endocytosis By The Asialoglycoprotein Receptor In Ethanol-Fed Mice: Implications For Studying The Role Of This Receptor In Alcoholic Apoptosis, Shana R. Dalton, Robert L. Wiegert, Cheryl R. Baldwin, Karen M. Kassel, Carol A. Casey

United States Public Health Resources

During receptor-mediated endocytosis (RME), extracellular molecules are internalized after being recognized and bound to specific cell surface receptors. In previous studies of the asialoglycoprotein receptor (ASGPR) in rats, we showed that ethanol impairs RME at multiple ASGPR sites. Ethanol administration has been shown to increase apoptosis, and we demonstrated increased sensitization to apoptotic induction in hepatocytes from ethanol-fed rats. Although a physiological role for the ASGPR has not been identified, investigators have shown its involvement in the uptake/clearance of apoptotic cells in vitvo. This suggests a potential role for the ASGPR in the removal of apoptotic cells, and the recent …

Methods. Survey data from 8 states and from poison control center data were analyzed. Illness incidence rates and incidence rate ratios were calculated.
Results. A total of 531 youths were identified with acute occupational pesticide-related illnesses. Insecticides were responsible for most of these illnesses (68%), most of which were of minor severity (79%). The average annual incidence rate among youths aged 15 to 17 years was 20.4 per billion hours worked, and the incidence rate ratio among youths vs adults …

Interferon Gamma Enhances Proteasome Activity In Recombinant Hep G2 Cells That Express Cytochrome P4502e1: Modulation By Ethanol, Natalia A. Osna, Dahn L. Clemens, Terrence M. Donohue Jr.

United States Public Health Resources

We tested the influence of IFNγ on proteasome activity in parental Hep G2 cells that do not metabolize ethanol, as well as in recombinant Hep G2-derived cells that express either or both alcohol dehydrogenase (ADH) and cytochrome P4502E1 (CYP2E1). IFNγ treatment increased proteasome activity in VL-17A (ADH⁺, CYP2E1⁺) and E-47 (CYP2E1⁺) cells, but not in Hep G2, VI-R2 (parental cells with empty vectors) or in VA-13 (ADH⁺) cells. Proteasome activation by IFNγ correlated positively with the level of CYP2E1 activity. Treatment of VL-17A cells with agents that inhibit CYP2E1 or the inducible …

Janosky, Michael J. Fine, Mahlon Raymund, Stephen A. Wilson, Inis Jane Bardella, Anne R. Medsger, Mary Patricia Nowalk

United States Public Health Resources

BACKGROUND: Despite strong evidence of the effectiveness of influenza vaccination, immunization rates have reached a plateau that is below the 2010 national goals. Our objective was to identify facilitators of, and barriers to, vaccination in diverse groups of older patients.
METHODS: A survey was conducted in 2000 by computer-assisted telephone interviewing of patients from inner-city health centers, Veterans Affairs (VA) outpatient clinics, rural practices, and suburban practices. The inclusion criteria were age ≥66 years and an office visit after September 30, 1998.
RESULTS: Overall, 1007 (73%) interviews were completed among 1383 patients. Influenza vaccination rates were 91% at VA clinics, …

Chronic Ethanol Consumption Impairs Receptor-Mediated Endocytosis Of Maa-Modified Albumin By Liver Endothelial Cells, Michael J. Duryee, Lynell W. Klassen, Thomas L. Freeman, Monte S. Willis, Dean J. Tuma, Geoffrey M. Thiele

United States Public Health Resources

Alcoholic liver disease has been associated with abnormalities in receptor-mediated endocytosis (RME) which results in abnormal degradation of metabolically altered proteins. Model systems using formaldehyde-modified albumin (f-Alb) have shown an impairment in RME following chronic alcohol consumption utilizing both in situ perfused rat livers and isolated rat liver endothelial cells (LECs). The discovery that alcohol metabolite derived aldehydes can modify proteins prompted a study to determine if malondialdehyde– acetaldehyde-modified albumin (MAA-Alb) would be degraded similar to that reported for f-Alb, and whether ethanol-fed rats would demonstrate an impaired RME with respect to this ligand which occurs as a consequence of …

The goal of the study was to obtain information from a representative sample of provincial health care facilities offering reproductive health services in KwaZulu Natal to meet the growing demand for HIV/AIDS-related services. Ninety-eight hospitals, community health centers, and clinics participated in the situation analysis that identified gaps in service delivery and determined priorities for service integration. Results of the study were presented to a large audience of Department of Health, …

Empowering Communities To Respond To Hiv/Aids: Ndola Demonstration Project On Maternal And Child Health: Operations Research Final Report, Hope Humana, Linkages, National Food And Nutrition Commission, Ndola District Health Management Team, Horizons Program, Zambia Integrated Health Project

HIV and AIDS

A pre–post intervention study conducted in Zambia by Horizons and local NGOs and governmental organizations demonstrated that HIV voluntary counseling and testing (VCT) and infant feeding counseling (IFC) to mothers attending maternal and child health (MCH) clinics are vital components of any mother-to-child transmission (MTCT) reduction strategy, whether or not antiretrovirals (ARVs) are available. These interventions enable mothers to make informed and healthy decisions. Data from the Ndola Demonstration Project yielded encouraging results from efforts to improve the capacity of mothers to make informed decisions about their own health and the health of their infant. The interventions succeeded in raising …

Rethinking Pegram : Why Erisa Health Benefits Administrators Should Have A Comprehensive Legal Requirement Of Fiduciary Duty, Bradley Ray Helfand

Public Health Theses

In the 2000 case Pegram v. Herdrich, the U.S. Supreme Court decided that administrators of health benefits plans covered by the Employee Retirement Income Security Act (ERISA) of 1974 do not have a fiduciary duty towards beneficiaries when making "mixed decisions" involving treatment and eligibility components. This thesis, Rethinking Pegram: Why ERISA Health Benefits Administrators Should Have a Comprehensive Legal Requirement of Fiduciary Duty, challenges the Court's opinion on grounds of legal precedent and public health ethics. While the legal critique of Pegram is an elaboration of earlier scholarship, the public health ethics critique represents a unique contribution …

Microfinance And Households Coping With Hiv/Aids In Zimbabwe: An Exploratory Study, Carolyn Barnes, Erica Keogh, Nontokozo Nemarundwe, Loveness Nyikahadzoi, Ellen Weiss

HIV and AIDS

This study, conducted in Zimbabwe, sought to better understand the relationship between a microfinance program, Zambuko Trust, and how microentrepreneurs’ households cope with the impact of HIV/AIDS. The study examined how HIV/AIDS is affecting Zambuko’s operations and what microfinance institutions (MFIs) can do to lessen the impact of HIV/AIDS on their clients and operations. The findings indicate several small yet important ways that MFI programs help microentrepreneurs and their families respond to these impacts through access to credit and business management training. Participation in a microfinance program led to income smoothing and better financial management, which can help households mitigate …

Effects Of The Pesticides Atrazine, Metoachlor And Diazinon And Binary Mixtures On Proliferation Of Human Fibroblasts, Kavita R. Dhanwada, Yijun Deng, Maureen E. Clayton

International Journal of Global Health

The frequent and heavy use of pesticides in agriculture has led to the contamination of surface and ground waters worldwide. Many questions have arisen about the human health effects of exposure to these pesticides and their mixtures. Most of the information about the adverse human health effects due to environmental contaminants comes from studies that focus on exposure to single rather than multiple contaminants since many of the environmental regulations regarding levels of xenobiotic contamination refer only to individual compounds. In this study, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) cell proliferation assays were performed with normal human fibroblasts to test the toxicity …

Evidence-Based Development Of Health And Family Planning Programs In Bangladesh And Ghana, James F. Phillips, Tanya C. Jones, Frank K. Nyonator, Shruti Ravikumar

Poverty, Gender, and Youth

This paper describes two initiatives that have used experimental studies to guide the development of community-based health and family planning programs. In Bangladesh and Ghana, factorial experiments were implemented in stages. An exploratory phase developed a service system for community-based health care; an experimental phase assessed the demographic impact of the system; a replication phase examined the transferability of the experimental program to a non-research setting; and a scaling-up phase facilitated the extension of the new system to the national health care program. All stages were guided by research, with questions, mechanisms, and outcomes shifting as the process developed. Large-scale …

Determinants Of Old-Age Mortality In Taiwan, Zachary Zimmer, Linda G. Martin, Hui-Sheng Lin

Poverty, Gender, and Youth

Relationships among socio-demographic characteristics, general assessments of health, and old-age mortality are well established in developed countries. There is also an increasing focus on the connection between early-life experiences and latelife health. This paper tests these and other associations using representative survey data from Taiwan on the population aged 60 and older in 1989, 1993, and 1996 that have been linked to data on deaths between 1989 and 1999 from a national death registry. The study also explores the possible influence of Taiwan’s Universal Health Insurance Program, instituted in 1995, and whether or not the survival of some groups of …

Estimating Mean Lifetime, John Bongaarts, Griffith Feeney

Poverty, Gender, and Youth

The life expectancy implied by current age-specific mortality rates is calculated with life table methods that are among the oldest and most fundamental tools of demography. We demonstrate that these conventional estimates of period life expectancy are affected by an undesirable “tempo effect.” The tempo effect is positive when the mean age at death is rising and negative when the mean age is declining. Estimates of the effect for females in three countries with high and rising life expectancy range from 1.6 years in the United States and Sweden to 2.4 years in France for the period 1980-95.

Completing The Fertility Transition In The Developing World: The Role Of Educational Differences And Fertility Preferences, John Bongaarts

Poverty, Gender, and Youth

This study summarizes patterns of educational differentials in wanted and unwanted fertility at different stages of the fertility transition based on data from DHS surveys in 57 less developed countries. As the transition proceeds, educational differentials in wanted fertility tend to decline and differentials in unwanted fertility tend to rise. An assessment of fertility patterns in more and less developed countries with low fertility concludes that these differentials are likely to remain substantial when less developed countries reach the end of their transitions. This finding implies that the educational composition of the population remains a key predictor of overall fertility …

The Ghana Community-Based Health Planning And Services Initiative: Fostering Evidence-Based Organizational Change And Development In A Resource-Constrained Setting, Frank K. Nyonator, John Koku Awoonor-Williams, James F. Phillips, Tanya C. Jones, Robert A. Miller

Poverty, Gender, and Youth

Research projects demonstrating ways to improve health services often fail to have an impact on what national health programs actually do. An approach to evidence-based policy development has been launched in Ghana that bridges the gap between research and program implementation. The Community-based Health Planning and Services (CHPS) initiative employs strategies tested in the successful Navrongo experiment to guide national health reforms that mobilize volunteers, resources, and cultural institutions to support community-based primary health care. Over the 1999 to 2002 period, 100 out of the 110 districts in Ghana adopted a CHPS initiative. This paper reviews features of the initiative …

Primary Schooling In Sub-Saharan Africa: Recent Trends And Current Challenges, Cynthia B. Lloyd, Paul C. Hewett

Poverty, Gender, and Youth

At the dawn of the twenty-first century we estimate that more than 37 million young adolescents aged 10-14 in sub-Saharan Africa will not complete primary school. Our estimates are based on data from nationally representative Demographic and Health Surveys from 26 countries, collectively representing 83 percent of the sub-Saharan youth population. This number is nearly twice the entire population of children aged 10-14 in the United States, virtually all of whom will complete primary school. Reducing the number of uneducated African youth is a primary objective of the United Nations as laid out in the Millennium Development Goal for education, …
