(Revista Mexicana de Pediatría 72 (1) 005-008, 2005-01)Objetivo. Conocer la variación estacional de los virus asociados a las infecciones respiratorias de niños hospitalizados. Material y métodos. En 1,017 niños hospitalizados por una enfermedad respiratoria aguda entre ... -
Vejigas animales como sitios para oviposición y desarrollo de moscas (Diptera: Cyclorrhapha) en el contexto de una tradición en Barva de Heredia, Costa Rica
(2008-06-01)Se realizó un recuento del número de vejigas dispersas en 15 manzanas del centro urbano de Barva, Heredia, luego de la celebración de las mascaradas, actividad enmarcada en las fiestas patronales de la ciudad. Adicionalmente ... -
Venenos de serpiente: de la investigación al tratamiento
(Acta méd. costarric, Vol. 54 (2), abril-junio, 2012, 2012)El presente trabajo ofrece una breve visión de cómo se ha enfrentado el problema del ofidismo en Costa Rica, y en especial, de cómo la investigación científica y tecnológica ha contribuido a tal fin. Se resumen los orígenes ... -
Venenos de serpientes de la familia Viperidae en América: Bioquímica y fisiopatología.
(2011)Se muestra una perspectiva general de las características bioquímicas de los principales tipos de toxinas presentes en los venenos de vipéridos americanos y la fisiopatología de estos envenenamientos. En la preparación ... -
Venom Composition and Diet of the Cantil Agkistrodon bilineatus howardgloydi (Serpentes: Viperidae)
(1999-12)The southernmost subspecies of the cantil, Agkistrodon bilineatus howardgloydi, occurs in almost all terrestrial habitats of the sector Santa Rosa National Park, in Guanacaste Conservation Area, Costa Rica. We obtained 21 ... -
Venom of Bothrops asper from Mexico and Costa Rica: Intraspecific variation and cross-neutralization by antivenoms
(2012-01)Bothrops asper is the species that induces the highest incidence of snakebite envenomation in southern Mexico, Central America and parts of northern South America. The intraspecies variability in HPLC profile and ... -
Venom of the Coral Snake Micrurus clarki: Proteomic Profile, Toxicity, Immunological Cross-Neutralization, and Characterization of a Three-Finger Toxin
(2016)Micrurus clarki is an uncommon coral snake distributed from the Southeastern Pacific of Costa Rica to Western Colombia, for which no information on its venom could be found in the literature. Using a 'venomics' approach, ... -
Venom of the crotaline snake Atropoides nummifer (jumping viper) from Guatemala and Honduras: comparative toxicological characterization, isolation of a myotoxic phospholipase A(2) homologue and neutralization by two antivenoms
(2001-07)A comparative study was performed on the venoms of the crotaline snake Atropoides nummifer from Guatemala and Honduras. SDS-polyacrylamide gel electrophoresis, under reducing conditions, revealed a highly similar pattern ... -
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, ... -
Venomic analysis of the poorly studied desert coral snake, Micrurus tschudii tschudii, supports the 3FTx/PLA2 dichotomy across Micrurus venoms
(2016)The venom proteome of the poorly studied desert coral snake Micrurus tschudii tschudii was unveiled using a venomic approach, which identified ¥38 proteins belonging to only four snake venom protein families. The ... -
Venomic and antivenomic analyses of the Central American coral snake, Micrurus nigrocinctus (Elapidae)
(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 ... -
Venomics and antivenomics of Bothrops erythromelas from five geographic populations within the Caatinga ecoregion of northeastern Brazil
(2015-01-30)The Caatinga lancehead, Bothrops erythromelas, is a medically relevant species, responsible for most of the snakebite accidents in most parts of its distribution range in northeastern Brazil. The spectrum and geographic ... -
Venoms of Micrurus coral snakes: evolutionary trends in compositional patterns emerging from proteomic analyses
(2016-11)The application of proteomic tools to the study of snake venoms has led to an impressive growth in the knowledge about their composition (venomics), immunogenicity (antivenomics), and toxicity (toxicovenomics). About ... -
El virus del Zika
(2016-01)El virus del Zika es un arbovirus emergente. Se transmite por medio de los mosquitos del género Aedes. Fue descrito por primera vez en mosquitos y monos del bosque Zika en Uganda, en 1947; posteriormente, en seres humanos ... -
Why myotoxin-containing snake venoms possess powerful nucleotidases?
(2013-01-25)The venom of the snake Bothrops asper causes muscle necrosis, pain and inflammation. This venom contains myotoxins which cause an increase in intracellular Ca2+ concentration and release of K+ and ATP from myotubes. ATP ... -
Wound exudate as a proteomic window to reveal different mechanisms of tissue damage by snake venom toxins
(2009)In light of the complexity of wound tissue, proteomic analysis may not clearly reveal the nature of the wound or the processes involved in healing. However, exudate associated with wounds may provide a “window” on cellular ... -
