Prey specificity of predatory venoms

Biological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.
ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.

Snake venom toxins: Potential anticancer therapeutics

Journal of Applied Toxicology, Volume 44, Issue 5, Page 666-685, May 2024.
Abstract Snake venom contains a cocktail of compounds dominated by proteins and peptides, which make up the toxin. The toxin components of snake venom attack several targets in the human body including the neuromuscular system, kidney and blood coagulation system and cause pathologies. As such, the venom toxins can be managed and used for the treatment

The Protective Action of Coutarea hexandra (Rubiaceae) on the Neuromuscular Blockade Induced by Lachesis muta muta (Viperidae: Crotalinae) Venom

BioMed Research International, Volume 2024, Issue 1, 2024.
Envenomations by snakes represent a neglected health problem in tropical and subtropical countries. In South America, Lachesis muta occasionally causes severe human envenomation, with treatment being conditioned to an unspecific antivenom. In this work, we examined the neutralizing ability of Coutarea hexandra stem bark hydroalcoholic extract (Ch‐E ...
