The scorpion Toxin Tf2 from Tityus fasciolatus Promotes Nav1.3 opening [PDF]
, 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)

Hyaluronidase: the spreading factor of Tityus serrulatus venom [PDF]
, 2018 Background: The hyaluronidase enzyme is generally known as a spreading factor in animal venoms. Although its activity has been demonstrated in several organisms, a deeper knowledge about hyaluronidase and the venom spreading process from the bite/sting site until its elimination from the victim's body is still in need.

Neurotransmitter evaluation in the hippocampus of rats after intracerebral injection of TsTX scorpion toxin [PDF]
, 2009 TsTX is an a-type sodium channel toxin that stimulates the discharge of neurotransmitters from neurons. In the present study we investigated which neurotransmitters are released in the hippocampus after TsTX injection and if they are responsible for ...

THE MOUSE AS AN EXPERIMENTAL MODEL FOR TITYUS SERRULATUS SCORPION ENVENOMING
Acta Cirurgica Brasileira, 1998 The scorpion toxin induces a number of physiological parameters alterations, as disturbance of cardiac rhythm, heart failure, shock, pancreatic hypersecretion, abortion, respiratory arrhytmias and pulmonary edema. As the purification of the venom fractions is a laborious process, one alternative for this would be the utilization of small animals.

Embriotoxic effects of maternal exposure to Tityus serrulatus scorpion venom [PDF]
Journal of Venomous Animals and Toxins including Tropical Diseases, 2008 Tityus serrulatus is the most venomous scorpion in Brazil; however, it is not known whether its venom causes any harm to the offspring whose mothers have received it. This study investigates whether the venom of T. serrulatus may lead to deleterious effects in the offspring, when once administered to pregnant rats at a dose that causes moderate ...

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.
