Pathophysiological effects caused by the venom of the social wasp Synoeca surinama.

Envenomation by wasp stings is a public health preoccupation, and signals after stings have variable effects depending on the number of attacks and individual sensitivities. Even with the high rate of wasp sting cases, the study of phatophysiological effects of the envenomation is still very incipient. In this context, early and accurate assessment of this prognostic can aid in the reduction of the symptomatology and complete remission of the later symptoms.

Cm-p5: an antifungal hydrophilic peptide derived from the coastal mollusk Cenchritis muricatus (Gastropoda: Littorinidae).

Antimicrobial peptides form part of the first line of defense against pathogens for many organisms. Current treatments for fungal infections are limited by drug toxicity and pathogen resistance. Cm-p5 (SRSELIVHQRLF), a peptide derived from the marine mollusk Cenchritis muricatus peptide Cm-p1, has a significantly increased fungistatic activity against pathogenic Candida albicans (minimal inhibitory concentration, 10 µg/ml; EC50, 1.

Nanoformulated antibiotics: the next step for pathogenic bacteria control.

The resistance of infectious bacteria to current antibiotics is a worldwide problem. Previous studies have demonstrated the efficacy of nanostructured molecules against pathogens as an innovative methodology for the development of novel drugs. Currently, 95% of properties limited pharmacies applicability such as low solubility, short half-life in the circulatory system, toxicity associated to controlled release and immunogenicity.
