Screening At Worksite Applying The Framingham Heart Study Score., Paulo A. Lotufo Dec 2002

Screening At Worksite Applying The Framingham Heart Study Score., Paulo A. Lotufo

Paulo A Lotufo

The first evaluation of class of occupation and cardiovascular risk factors in a Brazilian sample of civil servants. 1) context: Cardiovascular diseases are the main causes of death in Brazil. The high-risk approach to cardiovascular risk factors by screening test at worksite is one possible strategy of prevention. 2) objective: to verify the impact of a risk factors screening according to occupational levels. 3) type of study: cross-sectional 4) setting: occupational division of University of Sao Paulo 5) participants: 6,587 employees aged 20 to 69 years-old classified according three occupational grades (non-skilled, both manual and non-manual jobs; technical; faculty). 6) …


Cutting Edge: Persistent Viral Infection Prevents Tolerance Induction And Escapes Immune Control Following Cd28/Cd40 Blockade-Based Regimen, Thandi M. Onami, M. A. Williams, A. B. Adams, M. M. Durham, T. C. Pearson, R. Ahmed, C. P. Larsen Nov 2002

Cutting Edge: Persistent Viral Infection Prevents Tolerance Induction And Escapes Immune Control Following Cd28/Cd40 Blockade-Based Regimen, Thandi M. Onami, M. A. Williams, A. B. Adams, M. M. Durham, T. C. Pearson, R. Ahmed, C. P. Larsen

A continuing concern with CD28 and/or CD40 blockade-based strategies to induce tolerance and mixed chimerism is their potential to disrupt protective immunity to preexisting infections. In this report, we find that preexisting persistent infection with lymphocytic choriomeningitis virus (LCMV) clone 13 prevents the induction of tolerance, mixed chimerism, and donor-reactive T cell deletion. Mice continue to be refractory to tolerance induction even after viremia has been resolved and virus is present only at very low levels in peripheral tissues. Conversely, we find that the full tolerance regimen, or costimulation blockade alone, specifically inhibits already ongoing antiviral immune responses, leading to …


Molecular Cloning And Characterization Of A Novel Mouse Macrophage C-Type Lectin, Mmgl2, Which Has A Distinct Carbohydrate Specificity From Mmgl1, Thandi M. Onami, M. Tsuiji, M. Fujimori, Y. Ohashi, N. Higashi, S. M. Hendrick, T. Irimura Aug 2002

Molecular Cloning And Characterization Of A Novel Mouse Macrophage C-Type Lectin, Mmgl2, Which Has A Distinct Carbohydrate Specificity From Mmgl1, Thandi M. Onami, M. Tsuiji, M. Fujimori, Y. Ohashi, N. Higashi, S. M. Hendrick, T. Irimura

Thandi M. Onami

A novel mouse macrophage galactose-type C-type lectin 2 (mMGL2) was identified by BLAST analysis of expressed sequence tags. The sequence of mMGL2 is highly homologous to the mMGL, which should now be called mMGL1. The open reading frame of mMGL2 contains a sequence corresponding to a type II transmembrane protein with 332 amino acids having a single extracellular C-type lectin domain. The 3'-untranslated region included long terminal repeats of mouse early transposon. The Mgl2 gene was cloned from a 129/SvJ mouse genomic library and sequenced. The gene spans 7,136 base pairs and consists of 10 exons, which is similar to …

Macrophage receptors function in pattern recognition for the induction of innate immunity, in cellular communication to mediate the regulation of adaptive immune responses, and in the clearance of some glycosylated cells or glycoproteins from the circulation. They also function in homeostasis by initiating the engulfment of apoptotic cells. Evidence has suggested that macrophage receptors function to recognize cells that are destined for programmed cell death but not yet overtly apoptotic. We have examined the function of a macrophage receptor specific for unsialylated glycoproteins, known as the mouse macrophage galactose- and N-acetylgalactosamine-specific lectin (mMGL) (Ii et al., J. Biol. Chem. 265:11295-11298, …

During a viral response, Ag-specific effector T cells show dramatically increased binding by the mAb 1B11 and the lectin peanut agglutinin (PNA). We investigated the contribution of CD43 expression to 1B11 and PNA binding as well as its role in generation and maintenance of a CD8 T cell response. Analysis of CD43(-/-) mice revealed no increased 1B11 binding and reduced PNA binding on virus-specific CD8 T cells from -/- mice compared with +/+ mice. Furthermore, we examined the role of CD43 in the kinetics of an immune response. We show that CD43 expression modestly effects generation of a primary virus-specific …


Dengue And Hurricane Reconstruction - Text 2002, Frank Cortez Flores Mar 2002

Dengue And Hurricane Reconstruction - Text 2002, Frank Cortez Flores

Frank Cortez Flores

Unrelenting rains and savage winds, which accompany hurricanes, produce devastating mudslides and sustained flooding. In the wake of hurricanes, thousands of inhabitants face the plight of a greatly diminished capacity to go about their daily lives as a result of destroyed or severely-damaged homes, deteriorated living conditions, and increased health risks. Hurricanes inevitably aggravate the frail health of an already vulnerable segment of the population living both in and outside its destructive path. Repeated epidemics of dengue and dengue hemorrhagic fever afflicting millions of individuals occur annually in tropical and subtropical areas of the world, including The Caribbean and Central …

Migraine And Coronary Heart Disease In Women And Men, Paulo A. Lotufo Jan 2002

Migraine And Coronary Heart Disease In Women And Men, Paulo A. Lotufo

Paulo A Lotufo

Objective.—We evaluated migraine as an independent risk factor for subsequent coronary heart disease (CHD) events among women in the Women’s Health Study (WHS) and men in the Physicians’ Health Study (PHS). Background.—Although several studies have suggested that migraine is associated with increased risk of stroke, there are few and conflicting data on whether migraine predicts risk of future CHD events. Methods.—The WHS is an ongoing randomized, double-blind, placebo-controlled trial of low-dose aspirin and vitamin E in the primary prevention of cardiovascular disease and cancer in 39,876 women health professionals aged 45 years in 1993, and the PHS is a completed …

Retroviral Delivery Of Connexin Genes To Human Breast Tumor Cells Inhibits In Vivo Tumor Growth By A Mechanism That Is Independent Of Significant Gap Junctional Intercellular Communication, H. Qin, Q. Shao, H. Curtis, J. Galipeau, Daniel Belliveau, T. Wang, M. Alaoui-Jamali, D. Laird Dec 2001

Retroviral Delivery Of Connexin Genes To Human Breast Tumor Cells Inhibits In Vivo Tumor Growth By A Mechanism That Is Independent Of Significant Gap Junctional Intercellular Communication, H. Qin, Q. Shao, H. Curtis, J. Galipeau, Daniel Belliveau, T. Wang, M. Alaoui-Jamali, D. Laird

Daniel J. Belliveau

The mechanism by which gap junction proteins, connexins, act as potent tumor suppressors remains poorly understood. In this study human breast tumor cells were found to exhibit diverse gap junction phenotypes including (a) undetectable Cx43 and no intercellular communication (HBL100); (b) low levels of Cx43 and sparse intercellular communication (MDA-MB-231); and (c) significant levels of Cx43 and moderate intercellular communication (Hs578T). Although retroviral delivery of Cx43 and Cx26 cDNAs to MDA-MB-231 cells did not achieve an expected substantial rescue of intercellular communication, overexpression of connexin genes did result in a dramatic suppression of tumor growth when connexin-expressing MDA-MB-231 cells were …


Changes In The Transmission Of Tuberculosis In New York City From 1990 To 1999, Elvin H. Geng Dec 2001

Changes In The Transmission Of Tuberculosis In New York City From 1990 To 1999, Elvin H. Geng

Elvin H Geng

Background: Over the past decade, there has been a reduction in the incidence of tuberculosis in New York City and in the United States. However, the reduction has been confined mainly to U.S.-born persons. Understanding the reasons for the lack of reduction among non–U.S.-born persons may lead to new strategies for tuberculosis control. Methods: We performed DNA fingerprinting with the IS6110 insertion sequence of the organisms isolated from patients with culture-positive tuberculosis in northern Manhattan from 1990 to 1999. The goal was to identify the strains responsible for multiple infections, presumably through recent transmission (clusters of cases), as well as …
