Analysing chemical composition and antimicrobial activity of geopropolis from : HPLC-DAD and investigations.

This study evaluated the chemical profile, antimicrobial activity, and the presence of potentially toxic elements in geopropolis extracts produced by in the Recôncavo region of Bahia, Brazil. It was found that the major chemical compounds belong to the class of phenolic compounds, with emphasis on the presence of gallic acid. In this study, no potentially toxic elements were found in the analysed geopropolis.

Soybean oil addition to wheat bran-based diet improves laying hens' performance.

Background And Aim: Wheat bran (WB) is used extensively in animal feed. Despite its nutritional value, its use is limited because of its high-fiber content. We evaluated the effect of soybean oil on laying hen performance with maize meal partly replaced by WB.

[For the return of high vaccination coverage].

The global decline in vaccine coverage led the World Health Organization (WHO) in 2019 to define vaccine hesitation as one of the world's top ten threats to public health. In Brazil, the drop in vaccination coverage began in 2012, increasing from 2016, and was aggravated by the COVID-19 pandemic. The warning of low vaccination coverage is accompanied by the reintroduction of immunopreventable diseases such as measles.

Altered phagocytosis and morphogenesis of phenotypic switching-derived strains of the pathogenic Candida tropicalis co-cultured with phagocytic cells.

Background And Objective: Candida tropicalis is among the most prevalent human pathogenic yeast species. Switch states of C. tropicalis differ in virulence traits.
