Snake Venom and Antivenom Pharmacology

  SNAKE VENOM & ANTIVENOM Chemistry, Composition, Mechanisms and Pharmacology Abstract This integrated teaching session for Phase III MBBS students focused on the pharmacology and toxicology of snake venom and the principles of antivenom therapy. The lecture covered the chemistry, composition, mechanisms of action, and pharmacological effects of snake venoms and antivenoms. Rational use of antivenoms, indications, administration protocols, adverse reactions, and supportive management strategies were discussed. The session also highlighted the translational importance of venom-derived compounds in modern drug development. Recent advances in antivenom research, including recombinant human monoclonal antibodies, toxin-specific inhibitors, synthetic antibody technologies, and next-generation broad-spectrum antivenoms, were reviewed. Current discoveries and emerging approaches aimed at improving efficacy, safety, affordability, and accessibility of antivenom therapy were also explor...

Uaica gen. nov., a new genus of huntsman spiders from the Brazilian Amazonia (Araneae: Sparassidae)

Abstract

The new genus Uaica gen. nov. is proposed to include five new species, the type species, Uaica uatuma gen. et sp. nov. (♂♀) and U. mapia gen. et sp. nov. (♂) from Amazonas, U. carapiranga gen. et sp. nov. (♂♀), from Pará, U. karipuna gen. et sp. nov. (♂) from Rondônia and U. juruena gen. et sp. nov. (♀), from Mato Grosso, all from the Brazilian Amazonia. The new genus seems to be closely related to Caayguara Rheims, 2010, Meri Rheims & Jäger, 2022, Nungara Pinto & Rheims, 2016, and Sadala Simon, 1880. All species are described and illustrated, and a distribution map is provided.
