Background: The COVID-19 situation in Brazil is complex due to large differences the shape and size of regional epidemics. Understanding these patterns crucial understand future outbreaks SARS-CoV-2 or other respiratory pathogens country. Methods: We tested 97,950 blood donation samples for IgG antibodies from March 2020 2021 8 Brazil’s most populous cities. Residential postal codes were used obtain representative samples. Weekly age- sex-specific seroprevalence estimated by correcting crude...
SARS-CoV-2 serologic surveys estimate the proportion of population with antibodies against historical variants, which nears 100% in many settings. New approaches are required to fully exploit serosurvey data. Using a anti-Spike (S) protein chemiluminescent microparticle assay, we attained semi-quantitative measurement IgG titers serial cross-sectional monthly samples blood donations across seven Brazilian state capitals (March 2021−November 2021). an ecological analysis, assessed...
As nanopartículas magnéticas de óxido ferro têm chamado grande atenção em pesquisas recentes, devido a sua variedade aplicação diversas áreas. Essas podem ser produzidas por diferentes métodos, dentre os quais se citar, co-precipitação, microemulsão, hidrotérmico, sol-gel, entre outros. Entretanto nesses processos síntese, muitas vezes são utilizados solventes tóxicos e surfactantes que poderiam evitados utilizando síntese verde (green synthesis). Nesta produtos substituídos materiais verdes...
