Stability, distribution and use of antivenoms for snakebite envenomation in Latin America: Report of a workshop
(2009-05)
The issues of antivenom stability and distribution, and the training of health staff in the correct use of antivenoms in Latin America were discussed in a workshop held at Instituto Clodomiro Picado, Costa Rica, in September ...
Snake Venomics and Antivenomics of the Arboreal Neotropical Pitvipers Bothriechis lateralis and Bothriechis schlegelii
(2008-04-30)
We report the comparative proteomic characterization of the venoms of two related neotropical arboreal pitvipers from Costa Rica of the genus Bothriechis, B. lateralis (side-striped palm pit viper) and B. schlegelii (eyelash ...
The C-terminal region of a Lys49 myotoxin mediates Ca2þ influx in C2C12 myotubes
(2010-02)
Myotoxins are abundant components of snake venoms, being a significant public health problem worldwide. Among them, Lys49 phospholipase A2 homologue myotoxins cause extensive necrosis in skeletal muscle tissue. Their ...
Snake Venomics of Central American Pitvipers: Clues for Rationalizing the Distinct Envenomation Profiles of Atropoides nummifer and Atropoides picadoi
(2008)
We report the proteomic characterization of the Central American pitvipers Atropoides nummifer and
Atropoides picadoi. The crude venoms were fractionated by reverse-phase high-performance liquid
chromatography (HPLC), ...
Venom, venomics, antivenomics
(2009)
Venoms comprise mixtures of peptides and proteins tailored by Natural Selection to act on vital systems
of the prey or victim. Here we review our proteomic protocols for uncoiling the composition,
immunological profile, ...
Comparative study of the cytolytic activity of snake venoms from African spitting cobras (Naja spp., Elapidae) and its neutralization by a polyspecific antivenom
(2011-11)
Venoms of several Naja species found in Sub-Saharan Africa, and commonly known as "spitting cobras", induce a predominantly cytotoxic pattern of envenomings that may evolve into tissue necrosis and gangrene. Cytotoxic ...
Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus
(2014-12)
Four disintegrins were isolated from the venoms of the Central American viperid snakes Atropoides mexicanus (atropoimin), Bothrops asper (bothrasperin), Cerrophidion sasai (sasaimin), and Crotalus simus (simusmin). ...
Bothrops snake myotoxins induce a large efflux of ATP and potassium with spreading of cell damage and pain
(2010-07-26)
Myotoxins play a major role in the pathogenesis of the envenomations caused by snake bites in large parts of the world where this is a very relevant public health problem. We show here that two myotoxins that are major ...
Snake venomics and antivenomics: Proteomic tools in the design and control of antivenoms for the treatment of snakebite envenoming
(2009-03-06)
Snakebite envenoming represents a neglected tropical disease that has a heavy public health impact, particularly in Asia, Africa and Latin America. A global initiative, aimed at increasing antivenom production and ...
Profiling the venom gland transcriptomes of Costa Rican snakes by 454 pyrosequencing
(BMC Genomics, 12:259, 2011, 2011)
Background: A long term research goal of venomics, of applied importance for improving current antivenom
therapy, but also for drug discovery, is to understand the pharmacological potential of venoms. Individually ...
