Snake Venomics of the Central American Rattlesnake Crotalus simus and the South American Crotalus durissus Complex Points to Neurotoxicity as an Adaptive Paedomorphic Trend along Crotalus Dispersal in South America 

Calvete Chornet, Juan José; Sanz, Libia; Cid, Pedro; De La Torre, Pilar; Flores Díaz, Marietta; Dos Santos, María Cristina; Borges, Adolfo; Bremo, Adolfo; Angulo Ugalde, Yamileth; Lomonte, Bruno; Alape Girón, Alberto; Gutiérrez, José María (2010)
We report a comparative venomic and antivenomic characterization of the venoms of newborn and adult specimens of the Central American rattlesnake, Crotalus simus, and of the subspecies cumanensis, durissus, ruruima, and ...

Tissue pathology induced by snake venoms: How to understand a complex pattern of alterations from a systems biology perspective? 

Gutiérrez, José María; Rucavado Romero, Alexandra; Escalante Muñoz, Teresa; Lomonte, Bruno; Angulo Ugalde, Yamileth; Fox, Jay W. (2010-01)
The study of snake venom-induced local tissue pathology has been predominantly based on experimental designs and concepts that view tissue alterations from a dichotomous, homogeneous and reductionist perspective. Experimental ...

Snake Venomics of the Lesser Antillean Pit Vipers Bothrops caribbaeus and Bothrops lanceolatus: Correlation with Toxicological Activities and Immunoreactivity of a Heterologous Antivenom 

Gutiérrez, José María; Sanz, Libia; Escolano, José; Fernández Ulate, Julián; Lomonte, Bruno; Angulo Ugalde, Yamileth; Rucavado Romero, Alexandra; Warrell, David A.; Calvete Chornet, Juan José (2008-10)
The venom proteomes of the snakes Bothrops caribbaeus and Bothrops lanceolatus, endemic to the Lesser Antillean islands of Saint Lucia and Martinique, respectively, were characterized by reversephase HPLC fractionation, ...

Snake venomics of the South and Central American Bushmasters. Comparison of the toxin composition of Lachesis muta gathered from proteomic versus transcriptomic analysis 

Sanz, Libia; Escolano, José; Ferretti, Massimo; Biscoglio, Mirtha J.; Rivera, Elena; Crescenti, Ernesto J.; Angulo Ugalde, Yamileth; Lomonte, Bruno; Gutiérrez, José María; Calvete Chornet, Juan José (2008-04-30)
We report the proteomic characterization of the venoms of two closely related pit vipers of the genus Lachesis, L. muta (South American Bushmaster) and L. stenophrys (Central American Bushmaster), and compare the toxin ...

Trends in Snakebite Envenomation Therapy: Scientific, Technological and Public Health Considerations 

Gutiérrez, José María; Lomonte, Bruno; León Montero, Guillermo; Rucavado Romero, Alexandra; Chaves Mora, Fernando; Angulo Ugalde, Yamileth (2007)
The therapy of snakebite envenomation has been based on the parenteral administration of animal-derived antivenoms. Despite the success of this treatment at reducing the impact of snakebite mortality and morbidity, mostly ...

Cytotoxicity induced in myotubes by a Lys49 phospholipase A2 homologue from the venom of the snake Bothrops asper: Evidence of rapid plasma membrane damage and a dual role for extracellular calcium 

Villalobos Sole, Juan Carlos; Mora Rodríguez, Rodrigo Antonio; Lomonte, Bruno; Gutiérrez, José María; Angulo Ugalde, Yamileth (2007-12)
Acute muscle tissue damage, myonecrosis, is a typical consequence of envenomations by snakes of the family Viperidae. Catalytically-inactive Lys49 phospholipase A2 homologues are abundant myotoxic components in viperid ...

Snake venomics and antivenomics of Bothrops atrox venoms from Colombia and the Amazon regions of Brazil, Perú and Ecuador suggest the occurrence of geographic variation of venom phenotype by a trend towards paedomorphism 

Núñez Rangel, Vitelbina; Cid, Pedro; Sanz, Libia; De La Torre, Pilar; Angulo Ugalde, Yamileth; Lomonte, Bruno; Gutiérrez, José María; Calvete Chornet, Juan José (2009-11-02)
The venom proteomes of Bothrops atrox from Colombia, Brazil, Ecuador, and Perú were characterized using venomic and antivenomic strategies. Our results evidence the existence of two geographically differentiated venom ...

Purification of IgG and albumin from human plasma by aqueous two phase system fractionation 

Vargas Arroyo, Mariángela; Segura Ruiz, Álvaro; Herrera Vega, María; Villalta Arrieta, Mauren; Angulo Ugalde, Yamileth; Gutiérrez, José María; León Montero, Guillermo (2012-08)
The current shortages in human plasma products at global levels justify the development of new, cost effective plasma fractionation methods. We have developed a fractionation process to obtain immunoglobulin G (IgG) and ...

Venomic and antivenomic analyses of the Central American coral snake, Micrurus nigrocinctus (Elapidae) 

Fernández Ulate, Julián; Alape Girón, Alberto; Angulo Ugalde, Yamileth; Sanz, Libia; Gutiérrez, José María; Calvete Chornet, Juan José; Lomonte, Bruno (2011-01-31)
The proteome of the venom of Micrurus nigrocinctus (Central American coral snake) was analyzed by a “venomics” approach. Nearly 50 venom peaks were resolved by RP-HPLC, revealing a complex protein composition. Comparative ...

Myotoxic and cytolytic activities of dimeric Lys49 phospholipase A2 homologues are reduced, but not abolished, by a pH-induced dissociation 

Angulo Ugalde, Yamileth; Gutiérrez, José María; Soares, Andreimar Martins; Cho, Wonhwa; Lomonte, Bruno (2005-09-01)
Lys49 phospholipase A2 (PLA2) homologues are myotoxic proteins devoid of catalytic activity. Their toxic determinants map to the C-terminal region 115–129, which plays an effector role in membrane damage. The dimeric state ...
