Antivenomics of Atropoides mexicanus and Atropoides picadoi snake venoms: Relationship to the neutralization of toxic and enzymatic activities 

Antúnez Oliva, José; Fernández Ulate, Julián; Lomonte, Bruno; Angulo Ugalde, Yamileth; Sanz, Libia; Pérez, Alicia; Calvete Chornet, Juan José; Gutiérrez, José María (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’ ...

Phospholipase A2 enhances the endothelial cell detachment effect of a snake venom metalloproteinase in the absence of catalysis 

Bustillo, Soledad; García Denegri, María Emilia; Gay, Carolina; Van de Velde, Andrea C.; Acosta, Ofelia; Angulo Ugalde, Yamileth; Lomonte, Bruno; Gutiérrez, José María; Leiva, Laura (2015-10-05)
Microvessel disruption leading to hemorrhage stands among the most dangerous consequences of envenomings by snakes of the family Viperidae. A PIII metalloproteinase (SVMP), balteragin, purified from the venom of the snake ...

Stability, distribution and use of antivenoms for snakebite envenomation in Latin America: Report of a workshop 

Gutiérrez, José María; Fan, Hui Wen; Silvera, Carmen L.M.; Angulo Ugalde, Yamileth (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 ...

Venomous snakes of Costa Rica: biological and medical implications of their venom proteomic profiles analyzed through the strategy of snake venomics 

Lomonte, Bruno; Fernández Ulate, Julián; Sanz, Libia; Angulo Ugalde, Yamileth; Sasa Marín, Mahmood; Gutiérrez, José María; Calvete Chornet, Juan José (Journal of Proteomics XX (2014) XXX – XXX, Available online 24 February 2014, 2014-02-24)
In spite of its small territory of ~50,000 km2, Costa Rica harbors a remarkably rich biodiversity. Its herpetofauna includes 138 species of snakes, of which sixteen pit vipers (family Viperidae, subfamily Crotalinae), five ...

Two phospholipase A2 inhibitors from the plasma of Cerrophidion (Bothrops) godmani which selectively inhibit two different group-II phospholipase A2 myotoxins from its own venom: isolation, molecular cloning and biological properties 

Lizano González, Sergio; Angulo Ugalde, Yamileth; Lomonte, Bruno; Fox, Jay W.; Lambeau, Gérard; Lazdunski, Michel; Gutiérrez, José María (2000-03-15)
Myotoxic phospholipases A2 (PLA2s; group II) account for most of the muscle-tissue damage that results from envenomation by viperid snakes. In the venom of the Godman's viper (Cerrophidion godmani, formerly Bothrops godmani), ...

Snake Venomics of Central American Pitvipers: Clues for Rationalizing the Distinct Envenomation Profiles of Atropoides nummifer and Atropoides picadoi 

Angulo Ugalde, Yamileth; Escolano, José; Lomonte, Bruno; Gutiérrez, José María; Sanz, Libia; Calvete Chornet, Juan José (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), ...

Comparative study of the cytolytic activity of myotoxic phospholipases A2 on mouse endothelial (tEnd) and skeletal muscle (C2C12) cells in vitro 

Lomonte, Bruno; Angulo Ugalde, Yamileth; Rufini, Stefano; Cho, Wonhwa; Giglio, José Roberto; Ohno, Motoroni; Daniele, José Julían; Geoghegan, Patricia; Gutiérrez, José María (1999-01)
A rapid in vitro cytolytic effect of some myotoxic phospholipases A2 (PLA2s) isolated from the venoms of Viperidae snakes has been previously described. This study was undertaken to investigate if cytolytic activity is a ...

Snake Venomics and Antivenomics of the Arboreal Neotropical Pitvipers Bothriechis lateralis and Bothriechis schlegelii 

Lomonte, Bruno; Escolano, José; Fernández Ulate, Julián; Sanz, Libia; Angulo Ugalde, Yamileth; Gutiérrez, José María; Calvete Chornet, Juan José (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 ...

Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus 

Angulo Ugalde, Yamileth; Castro Godínez, Adriana; Lomonte, Bruno; Rucavado Romero, Alexandra; Fernández Ulate, Julián; Calvete Chornet, Juan José; Gutiérrez, José María (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). ...

Myotoxic phospholipases A2 in Bothrops snake venoms: Effect of chemical modifications on the enzymatic and pharmacological properties of bothropstoxins from Bothrops jararacussu 

Andrião Escarso, Silvia H.; Soares, Andreimar Martins; Rodrigues, Veridiana M.; Angulo Ugalde, Yamileth; Díaz Oreiro, Cecilia; Lomonte, Bruno; Gutiérrez, José María; Giglio, José Roberto (2000-08)
Venoms from eight Bothrops spp. were fractionated by ion-exchange chromatography on CM-Sepharose at pH 8.0 for the purification of myotoxins. Chromatographic profiles showed differences regarding myotoxic components among ...
