Spinal Anesthesia Failure Following Wasp Envenomation: A Case Series of Two Patients. [PDF]

Clin Case Rep
ABSTRACT Spinal anesthesia is highly effective, and complete failure in healthy patients is rare. Wasp venom contains neuroactive peptides capable of modifying sodium‐channel function and inducing neuroinflammation, but its impact on neuraxial anesthesia has not been previously reported. We describe two healthy ASA I males who developed complete spinal

Animal Venom Pharmacological Resources: Exploiting Bioactive Peptides to Target Multi-Drug-Resistant Bacteria. [PDF]

Biochem Res Int
Background The escalating rise of multi–drug‐resistant (MDR) bacterial strains significantly threatens global health, creating a “silent pandemic” prompted by natural selection, gene mutation, and horizontal gene transfer. This crisis is worsened by the deficit in the development of new treatments, necessitating the innovative discovery of new potent ...
