Shedding Light on the Dentition and Venom Delivery System of the Rear-Fanged Snake, (Serpentes: Dipsadidae: Tachymenini) from Chile.

Although the rear-fanged snake (formerly named ) causes ophidian accidents with clinical importance in Chile, the anatomical and histological characterizations of the venom delivery system (venom gland and fang) of this species still remain unknown. This study describes the dentition and characteristics of fangs and their ontogenetic variations in . Moreover, histological and histochemistry analyses of the venom glands of this species are presented.

A paraguayan toad Rhinella schneideri preparation based on Mbya tradition increases mitochondrial bioenergetics with migrastatic effects dependent on AMPK in breast cancer cells.

Ethnopharmacological Relevance: In Paraguay, healers from the Mbya culture treat cancer with a recipe prepared with the native toad Rhinella schneideri. However, the chemical composition and biological effects of the recipe remain unknown.

Aim Of The Study: The aim is to determine the composition of the traditional preparation made using the toad R.
