Resurrexit, sicut dixit, alleluia. Snake venomics from a 26-years old polyacrylamide focusing gel
(2012)
A 26-year-old dried polyacrylamide gel, cast in presence of an immobilized pH gradient and
containing focused proteins from the venoms of a northern black-tailed rattlesnake (Crotalus
molossus molossus), and of a western ...
Neutralization of local tissue damage induced by Bothrops asper (terciopelo) snake venom
(1998-11)
Local tissue damage represents a serious consequence of Bothrops asper envenomations. It encompasses a complex series of alterations, including myonecrosis, dermonecrosis, hemorrhage and edema. Due to its rapid development ...
Comparative study on the ability of IgG and Fab sheep antivenoms to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper (terciopelo) snake venom
(2000-02)
The ability of sheep antivenoms, consisting of whole IgG molecules or Fab fragments, to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper venom was comparatively studied in mice. The two antivenoms ...
Caracterización proteómica, funcional e inmunoneutralización del veneno de la serpiente Porthidium porrasi de Costa Rica
(2019-10)
Con el fin de generar conocimiento de base sobre los venenos de las serpientes que habitan Costa Rica, en este proyecto se realizó la caracterización proteómica, funcional e inmunoneutralización del veneno de la serpiente ...
Antivenomics of Atropoides mexicanus and Atropoides picadoi snake venoms: Relationship to the neutralization of toxic and enzymatic activities
(2010-09-30)
Viperid snakes of the genus Atropoides are distributed in Mexico and Central America and, owing to their size and venom yield, are capable of provoking severe envenomings in humans. This study evaluated, using an ‘antivenomics’ ...
Antimicrobial activity of myotoxic phospholipases A2 from crotalid snake venoms and synthetic peptide variants derived from their C-terminal region
(2005)
A short peptide derived from the C-terminal region of Bothrops asper myotoxin II, a Lys49 phospholipase A2 (PLA2), was
previously found to reproduce the bactericidal activity of its parent molecule. In this study, a panel ...
Homogenates of skeletal muscle injected with snake venom inhibit myogenic differentiation in cell culture
(2013-02)
Introduction: Viperid snakebite envenomings are characterized by muscle necrosis and a deficient regenerative response. Methods: Homogenates from gastrocnemius muscles of mice injected with the venom of the snake Bothrops ...
Novel catalytically-inactive PII metalloproteinases from a viperid snake venom with substitutions in the canonical zinc-binding motif
(2016-10-12)
Snake venom metalloproteinases (SVMPs) play key biological roles in prey immobilization
and digestion. The majority of these activities depend on the hydrolysis of relevant protein substrates
in the tissues. Hereby, we ...
Proteogenomic analysis of the Clostridium difficile exoproteome reveals a correlation between phylogenetic distribution and virulence potential
(2020)
C. difficile induces antibiotic-associated diarrhea due to the action of two secreted toxins, TcdA and TcdB. A considerable range of virulence among C. difficile strains has been widely reported. During a hospital outbreak, ...
Intravascular hemolysis induced by the venom of the Eastern coral snake, Micrurus fulvius, in a mouse model: Identification of directly hemolytic phospholipases A2
(Toxicon 90, 2014)
Intravascular hemolysis has been described in envenomings by the Eastern coral snake,
Micrurus fulvius, in dogs. An experimental model of intravascular hemolysis was developed
in mice after intravenous (i.v.) injection ...
