We examined the association between community violence exposure and childhood asthma risk in a multilevel, multimethod, longitudinal study controlling for individual- and neighbourhood-level confounders and pathway variables. Analyses included 2,071 children aged 0-9 yrs at enrolment from the Project on Human Development in Chicago Neighborhoods. Multilevel logistic regression models estimated ...
Disparities in verbal ability, a major predictor of later life outcomes, have generated widespread debate, but few studies have been able to isolate neighborhood-level causes in a developmentally and ecologically appropriate way. This study presents longitudinal evidence from a large-scale study of >2,000 children ages 6-12 living in Chicago, along with their caretakers, who were followed where...
We sought design principles for a vaccine to prevent HIV transmission to women by identifying correlates of protection conferred by a highly effective live attenuated SIV vaccine in the rhesus macaque animal model. We show that SIVmac239Δnef vaccination recruits plasma cells and induces ectopic lymphoid follicle formation beneath the mucosal epithelium in the rhesus macaque female reproductive ...
Based on an exploratory case study regarding the types of institutions funding the research and development to obtain new tuberculosis vaccines, this article intends to provoke discussion regarding the provision of new vaccines targeting neglected disease. Although our findings and discussion are mainly relevant to the case presented here, some aspects are more generally applicable, especially ...
Purified and concentrated Venezuelan equine encephalitis (VEE) virus derived from tissue cultures, rendered noninfectious by ionizing radiation with retention of in vitro serological activity, also retained a high level of immunogenicity. In mice, fluid vaccines afforded excellent protection against lethal challenge with homologous Trinidad strain VEE virus. A direct relationship was observed b...
Abstract Background: Rabies is the most important zoonosis in country. Anti-viral antibody conjugated with Fluorescein Isothiocyanate (FITC), is used for diagnosis of Rabies. We import this reagent from abroad. In this study we aimed to prepare this conjugated fluorescein antibody and assess its utility. Materials and methods: Rabbits were immunized with rabies vaccine, then serum samples ...
The immunogenic response of mice vaccinated intranasally or subcutaneously with increasing doses of a purified, concentrated intact A(2)/Taiwan influenza vaccine or its Tween-ether derived vaccines was compared. Immunogenicity was measured by serum neutralization and hemagglutination-inhibition antibodies, lung lesions scores, and protection against respiratory challenge with live airborne infl...
BACKGROUND A nucleotide change from U to C at position 472 in the 5' non-coding region of the type 3 poliovirus is associated with increased neurovirulence. Moreover, the proportion of type 3 polioviruses containing this mutation (472-C revertants) correlates with the neurovirulence of a particular sample. We used mutant analysis by PCR and restriction-enzyme cleavage (MAPREC) to estimate the n...
Despite evidence that vaccinating schoolchildren against influenza is effective in limiting community-level transmission, the United States has had a long-standing government strategy of recommending that vaccine be concentrated primarily in high-risk groups and distributed to those people who keep the health system and social infrastructure operating. Because of this year's influenza vaccine s...
Hemagglutinin (HA) glycoprotein is the dominant antigen of current influenza vaccines and antigenic drift requires a seasonal vaccine. The stem region HA conserved therefore promising target for universal Understanding specific response crucial in vaccine development. We hypothesize that maternal vaccination with would result boost antibodies higher concentrations neonatal cord blood. Two paral...
