Isolation of basic myotoxins from Bothrops Moojeni and Bothrops Atrox snake venoms

Toxicon, 1990
Three myotoxins, one from the venom of Bothrops atrox and two from the venom of B. moojeni, were isolated by ion-exchange chromatography on CM-Sephadex C-25. The three toxins are basic proteins with an estimated mol. wt of about 13,500, and similar amino acid compositions.

Heparin-antivenom association: differential neutralization effectiveness in Bothrops atrox and Bothrops erythromelas envenoming [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2001
Heparin, in some regions of Brazil has been used in the treatment of bothropic accidents, but the data found in the literature are inconclusive about its effectiveness. The venoms of Bothrops atrox and of B. erythromelas were characterized according to their biological activities. The capacity of heparin in neutralizing these activities was tested with

A sensory ecology approach to understanding snakebites: Influence of sensory cues on the strike of the lancehead pitviper

Journal of Zoology, Volume 329, Issue 3, Page 237-246, July 2026.
Snakes are notable for having a broad range of predators and one of the most diverse repertoires of defensive behaviors. During heightened responses to aversive stimuli, one of the behaviors displayed is the venomous bite, particularly relevant because it triggers snakebite incidents in humans.

Development of a sensitive enzyme immunoassay (ELISA) for specific identification of Lachesis acrochorda venom

Journal of Venomous Animals and Toxins including Tropical Diseases, 2012
The snake genus Lachesis provokes 2 to 3% of snakebites in Colombia every year. Two Lachesis species, L. acrochorda and L. muta, share habitats with snakes from another genus, namely Bothrops asper and B. atrox.

Generalist With a Narrow Niche Breadth: Feeding Ecology and Seed Germination Effectiveness of a Large Canid Within a Silvicultural Matrix

Austral Ecology, Volume 51, Issue 6, June 2026.
Diet: The generalist canid exhibits a narrow niche breadth (0.12), consuming native plants (100% frequency) and animals (85%). Birds dominate animal prey (74%), peaking in the dry season, while Solanaceae plants dominate plant food (100%), peaking in the rainy season.

Loss of Striatal Bradykinin B2 Receptor Alters Anxiety and Motivational Behaviors in Male Mice

The FASEB Journal, Volume 40, Issue 10, 31 May 2026.
Impaired signaling of the bradykinin B2 receptor (B2R) in dorsal striatal neurons decreases anxiety‐like behavior and sucrose preference while enhancing voluntary running in mice. These results reveal a novel role for B2R in dopaminergic circuits that modulate motivation and emotional behavior.
