Antivenom potential of the latex of Jatropha mutabilis baill. (Euphorbiaceae) against Tityus stigmurus venom: Evaluating its ability to neutralize toxins and local effects in mice.

Ethnopharmacological Relevance: Species of the Jatropha genus (Euphorbiaceae) are used indiscriminately in traditional medicine to treat accidents involving venomous animals. Jatropha mutabilis Baill., popularly known as "pinhão-de-seda," is found in the semi-arid region of Northeastern Brazil.

Clinical spectrum of congenital Zika virus infection in Brazil: Update and issues for research development.

This review aimed to provide an update on the morphological and/or functional abnormalities related to congenital Zika virus (ZIKV) infection, based on primary data from studies conducted in Brazil since 2015. During the epidemic years (2015-2016), case series and pediatric cohort studies described several birth defects, including severe and/or disproportionate microcephaly, cranial bone overlap, skull collapse, congenital contractures (arthrogryposis and/or clubfoot), and visual and hearing abnormalities, as part of the spectrum of Congenital Zika Syndrome (CZS). Brain imaging abnormalities, mainly cortical atrophy, ventriculomegaly, and calcifications, serve as structural markers of CZS severity.

Preliminary evaluation of the toxicological, antioxidant and antitumor activities promoted by the compounds 2,4-dihydroxy-benzylidene-thiosemicarbazones an in silico, in vitro and in vivo study.

Thiosemicarbazones are promising classes of compounds with antitumor activity. For this study, six 2,4-dihydroxy-benzylidene-thiosemicarbazones compounds were synthesized. These compounds were submitted to different assays in silico, in vitro and in vivo to evaluate the toxicological, antioxidant and antitumor effects.
