the rational use of insecticides largely depends on a broad knowledge of the susceptibility and irritability levels of malaria vectors to currently used insecticides especially pyrethroids. in this study the susceptibility and irritability levels of anopheles stephensi and an.culicifacies to ddt 4%,malathion 5%, propoxur 0.1%, deltamethrin 0.025%, lambdacyhalothrin 0.1%, cyfluthrin 0.1% and per...

The reasons why aminoglycosides are bactericidal have not been not fully elucidated, and evidence indicates that the cidal effects are at least partly dependent on iron. We demonstrate that availability of iron markedly affects the susceptibility of the facultative intracellular bacterium Francisella tularensis strain SCHU S4 to the aminoglycoside gentamicin. Specifically, the intracellular dep...

AIMS It is unclear how the prevalence of diabetes in Asian Indians in urban India compares to that of race/ethnic groups in the US that may have different underlying susceptibilities. Therefore we examined ethnic variations in the prevalence of type 2 diabetes, iIFG, iIGT, IFG+IGT, and the associated risk factors in Asian Indians in Chennai, India, and Whites, Blacks, and Hispanics in the Unite...

OBJECTIVE To assess possible differences in the frequency of HLA-DQB1 risk genotypes and the emergence of signs of beta-cell autoimmunity among three geographical regions in Finland. RESEARCH DESIGN AND METHODS The series comprised 4,642 children with increased HLA-DQB1-defined genetic risk of type 1 diabetes from the Diabetes Prediction and Prevention (DIPP) study: 1,793 (38.6%) born in Turk...

BACKGROUND The strikingly young age of new variant Creutzfeldt-Jacob disease (vCJD) cases remains unexplained. Age dependent susceptibility to infection has been put forward, but differential dietary exposure to contaminated food products in the UK population according to age and sex during the bovine spongiform encephalopathy (BSE) epidemic may provide a simpler explanation. METHODS Using re...

Human monocytes express interleukin-2 receptor beta (IL-2R beta) constitutively; however, the function of these receptors has not been fully delineated. We discovered that IL-2R beta directs two biologic activities in human monocytes, the release of granulocyte-macrophage colony-stimulating factor (GM-CSF) and increased susceptibility to lysis by lymphokine-activated killer cells (LAK) cells. H...

Single variant analysis in genome-wide association studies (GWAS) has been proven to be successful in identifying thousands of genetic variants associated with hundreds of complex diseases. However, these identified variants only explain a small fraction of inheritable variability in many diseases, suggesting that other resources, such as multilevel genetic variations, may contribute to disease...

Selective serotonin reuptake inhibitors (SSRIs) are reported to be associated with increased bleeding tendency. While findings of recent studies explain a lot about the pathophysiology of this side-effect, there is a general tendency to discontinue SSRIs as harmful medications. We report two instances of dose-dependent relations between sertraline and bleeding tendency. Bleeding diathesis was a...

This study contributes to the literature about the effects of space and place on health by introducing a socio-territorial approach to urban health disparities in West Africa. It explores how urban spaces, specifically neighbourhoods, are shaped by social and economic relations and strategies of territorial control. We examine the potential influence of socio-territorial processes on vulnerabil...

Strain Rv6, a streptomycin-independent reverse mutant of Salmonella abortus-ovis, multiplied and disseminated in vivo to a lesser extent than the virulent parental strain 15/5, as determined by subcutaneous inoculation of two outbred strains of mice with different susceptibilities to salmonella infection. This lower virulence of strain Rv6 was not modified by 10 passages in susceptible mice. Va...
