Degradomics for large‐scale mechanistic insights on proteases and proteolysis in human health

The FEBS Journal, Volume 293, Issue 13, Page 3881-3898, July 2026.
Proteolysis has an important role in human disease but remains relatively unexplored. Degradomics, the uncovering of proteolysis in tissues, cells, and proteins, uses mass spectrometry‐based terminomics to identify protein termini occurring therein (forward degradomics) and to define the actions of proteases (reverse degradomics).

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.

Complete Mitochondrial Genome of Ovophis makazayazaya (Viperidae, Crotalinae) and Phylogenetic Analysis

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study sequenced and annotated the complete 17,230 bp mitochondrial genome of Ovophis makazayazaya, which contains 13 protein‐coding genes (PCGs), 2 rRNAs, 22 tRNAs, and a D‐loop region, with a significant AT bias (57.2%). Phylogenetic analyses confirmed its placement within Crotalinae, and all PCGs showed evidence of purifying selection (Ka/Ks < 1)

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.

Discovery of Neuroprotective Venom‐Derived Candidates From Naja Mandalayensis in mHippoE‐18 Cells Via Fractionation and Proteomic Mapping

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Venom‐derived peptide diversity from Naja mandalayensis reveals bioactive subfractions capable of modulating neuronal oxidative stress responses. Integration of RP‐HPLC fractionation and proteomics identifies toxin families associated with improved mitochondrial function and cellular integrity in mHippoE‐18 cells, supporting venoms as a platform for ...

Synthesis, characterization and utilization of a new series of 1,2,3-triazole derivatives to neutralize some toxic activities of Bothrops jararaca snake venom

Brazilian Journal of Pharmaceutical Sciences, 2023
Snake envenomation is a public health problem, and while serum therapy prevents death, the local effects of venoms can lead to amputations or morbidities. Thus, alternative treatments deserve attention. In this study, we tested eight derivatives of 1,2,3-
