With no effective drug‐based prevention strategies available for chemotherapy‐induced peripheral neuropathy (CIPN), research in neuroprotective approaches has grown. Of particular interest is mechanical compression, which may protect nerves by temporarily reducing blood flow during treatment. The authors here conducted a prospective trial in women with

[Scorpion toxins and defensins].
Les venins de scorpion contiennent un grand nombre de neurotoxines peptidiques qui constituent un ensemble de familles moléculaires à haut degré de polymorphisme, mais qui ont en commun une architecture semblable. Cette architecture se retrouve dans des peptides antibactériens circulants de la famille des défensines, qui s'apparentent tout ...

To date, several families of peptide toxins specifically interacting with ion channels in scorpion venom have been described. One of these families comprise peptide toxins (called KTxs), known to modulate potassium channels.

This study investigates the phytochemical profile and biological potential of Atriplex halimus L. and Marrubium deserti De Noé extracts. Polyphenolic constituents are identified using UHPLC‐MS/MS analysis, complemented by TPC and TFC evaluations. Antioxidant activities are determined via DPPH, ABTS, and FRAP assays, while antimicrobial efficacy is ...

Scorpion toxins specific for Na+‐channels [PDF]
Na+‐channel specific scorpion toxins are peptides of 60–76 amino acid residues in length, tightly bound by four disulfide bridges. The complete amino acid sequence of 85 distinct peptides are presently known. For some toxins, the three‐dimensional structure has been solved by X‐ray diffraction and NMR spectroscopy.

Scorpion venom allergies. Report of three cases. [PDF]
Scorpion envenomations are widespread in many countries around the world. In Algeria, Androctonus australis hector (Aah) and Buthus occitanus tunetanus (Bot) are the cause of the greatest number of envenomations by scorpions and are responsible for ...

Integration of phylogenomics and molecular modeling reveals lineage-specific diversification of toxins in scorpions [PDF]
Scorpions have evolved a variety of toxins with a plethora of biological targets, but characterizing their evolution has been limited by the lack of a comprehensive phylogenetic hypothesis of scorpion relationships grounded in modern, genome-scale ...

Spinal Anesthesia Failure Following Wasp Envenomation: A Case Series of Two Patients
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

Bioactive peptides in cancer and inflammation: Mechanisms, model systems and clinical translation
Bioactive peptides (BAPs) derived from host, marine, insect, plant and synthetic sources share cationic, amphipathic structures adopting α‐helical, β‐sheet or cyclic conformations. These features underlie anti‐cancer effects, including membrane disruption, apoptosis and cell‐cycle arrest, anti‐metastatic activity, reduced invasion and migration, and ...
