Cancer therapeutics inspired by defense mechanisms in the animal kingdom
Evolutionary Applications, Volume 13, Issue 7, Page 1681-1700, August 2020., 2020 Abstract Many animals have evolved toxins to defend themselves from predators and hunt prey. These toxins have been honed over millions of years by the unique selective pressures on each organism leading to a vast array of potent bioactive compounds, many of which have therapeutic potential.

Supercharged Proteins and Polypeptides
Advanced Materials, Volume 32, Issue 20, May 22, 2020., 2020 Natural proteins with high net charges can be an inspiration for scientists to artificially supercharge other protein entities. Recent findings show that supercharging proteins allows for control of their properties such as temperature resistance and catalytic activity.

Scorpion species of medical importance in the Brazilian Amazon: a review to identify knowledge gaps
Journal of Venomous Animals and Toxins including Tropical Diseases, 2021 Scorpionism is a relevant medical condition in Brazil. It is responsible for most accidents involving venomous animals in the country, which leads to severe symptoms that can evolve to death. In recent years, an increase of almost 50% in the incidence of

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.

The Scorpion Toxin Tf2 from Tityus fasciolatus Promotes Nav1.3 Opening. [PDF]
PLoS ONE, 2015 We identified Tf2, the first β-scorpion toxin from the venom of the Brazilian scorpion Tityus fasciolatus. Tf2 is identical to Tb2-II found in Tityus bahiensis. We found that Tf2 selectively activates human (h)Nav1.3, a neuronal voltage-gated sodium (Nav)

The Identities of Tityus floridanus and Tityus tenuimanus (Scorpiones, Buthidae)
The Florida Entomologist, 1984 The taxonomic status of the 2 nominal species of the genus Tityus C. L. Koch described from the United States is revised. Tityus floridanus Banks, 1904, from Key West, Florida, is a junior synonym of Tityus dasyurus dasyurus Pocock, 1897, from Puerto Rico and St. Thomas (U. S. Virgin Islands).
