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.

Proteomic endorsed transcriptomic profiles of venom glands from Tityus obscurus and T. serrulatus scorpions. [PDF]

PLoS ONE, 2018
Except for the northern region, where the Amazonian black scorpion, T. obscurus, represents the predominant and most medically relevant scorpion species, Tityus serrulatus, the Brazilian yellow scorpion, is widely distributed throughout Brazil, causing ...

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.

[des-arg(1)]-proctolin: a novel nep-like enzyme inhibitor identified in tityus serrulatus venom

, 2021
The scorpion Tityus serrulatus venom comprises a complex mixture of molecules that paralyzes and kills preys, especially insects. However, venom components also interact with molecules in humans, causing clinic envenomation.

What do we know about some of the most conspicuous scorpion species of the genus Tityus? A historical approach

Journal of Venomous Animals and Toxins including Tropical Diseases, 2015
In the present study, comments are proposed on historical aspects of the most conspicuous scorpion species of the genus Tityus found in Brazil. Both Tityus bahiensis (Perty) and Tityus serrulatus Lutz & Mello are better known for their infamous ...

Parthenogenesis in scorpions: some history - new data

Journal of Venomous Animals and Toxins including Tropical Diseases, 2008
Parthenogenesis, a rare phenomenon in Chelicerates, apart from mites, is reviewed in scorpions, notably Tityus serrulatus Lutz & Mello from Brazil, Tityus columbianus (Thorell) from Colombia and Tityus metuendus Pocock from Peru and Brazil.

Sustained Ventricular Tachycardia and Cardiogenic Shock due to Scorpion Envenomation

Case Reports in Medicine, Volume 2014, Issue 1, 2014., 2014
We describe a case of severe scorpion envenomation in an adult patient, with the presence of very rapid sustained ventricular tachycardia followed by cardiogenic shock, which was reversed by scorpion antivenom administration. Scorpion venom causes cardiac changes that can lead to an environment favoring arrhythmogenesis.
