Neutralizing effects of Mimosa tenuiflora extracts against inflammation caused by Tityus serrulatus scorpion venom. [PDF]

Biomed Res Int, 2014
Scorpion bite represents a significant and serious public health problem in certain regions of Brazil, as well as in other parts of the world. Inflammatory mediators are thought to be involved in the systemic and local immune response induced by Tityus serrulatus scorpion envenomation.

Mass spectrometry‐based top‐down and bottom‐up approaches for proteomic analysis of the Moroccan Buthus occitanus scorpion venom

FEBS Open Bio, Volume 11, Issue 7, Page 1867-1892, July 2021., 2021
Buthus occitanus scorpion possesses highly toxic venom. This article describes the first proteomic screening of the Moroccan B. occitanus venom. Our findings highlight the complexity and the toxin diversity of this venom. The most representative compounds are neurotoxins.

Reciprocal transplantation of the heterotrophic coral Tubastraea coccinea (Scleractinia: Dendrophylliidae) between distinct habitats did not alter its venom toxin composition

Ecology and Evolution, Volume 10, Issue 4, Page 1794-1803, February 2020., 2020
Toxin complexity in the alien coral Tubastraea coccinea is conserved and co‐evolved with innovation of the venom delivery system. Morphological development of the coral and phenotypic expression of the venom and delivery system is not modulated by habitat pressures over short periods of time.
