Evaluación del nicho ecológico deformas larvales de Aedes aegypti y Culex quinquefasciatus (Díptera: Culicidae) en una comunidad urbana de San José, Costa Rica
(2007)Observations related to the width and overlap of the ecological niche for larval forms of Aedes aegypti and Culex quinquefasciatus in artificial containers were performed using the data obtained during two laval surveys ... -
Evaluación proteómica y toxinológica del veneno de Hemachatus haemachatus y su comparación con venenos de cobras del genero Naja sp. en términos de inmunoreactividad y neutralización cruzada para la preparación de un antiveneno poliespecífico para África
(2020)Las cobras representan el grupo de serpientes clínicamente más relevantes de la familia Elapidae en África, dentro de los cuales los géneros Naja y Hemachatus incluyen serpientes con venenos neurotóxicos y citotóxicos. ... -
Evaluation of antivenoms in the neutralization of hyperalgesia and edema induced by Bothrops jararaca and Bothrops asper snake venoms
(2002-10)Neutralization of hyperalgesia induced by Bothrops jararaca and B. asper venoms was studied in rats using bothropic antivenom produced at Instituto Butantan (AVIB, 1 ml neutralizes 5 mg B. jararaca venom) and polyvalent ... -
Evaluation of growth in diesel fuel and surfactants production ability by bacteria isolated from fuels in Costa Rica
(2012)A total of 149 bacterial strains previously isolated from fuels stored in Costa Rica were selected in terms of their ability to grow aerobically in diesel and produce bioemulsifier active compounds. The diesel growth was ... -
Evaluation of predictive maps for Aedes aegypti larval habitats in two urban areas of Costa Rica
(2011-12)The abundance of Aedes aegypti can be associated with urban structure and tree cover, which conceals and protects containers. The purpose of this study was to create and evaluate predictive maps for Ae. Aegypti larval ... -
Evaluation of the neutralizing ability of antivenoms for the treatment of snake bite envenoming in Central America
(1996)De nombreuses envenimations ophidiennes en Amérique centrale sont dues aux crotales (famille des Viperidae) parmi lesquels Bothrops asper est le principal responsable. Quelques accidents sont provoqués par les serpents ... -
Evaluation of the preclinical efficacy of four antivenoms, distributed in sub-Saharan Africa, to neutralize the venom of the carpet viper, Echis ocellatus, from Mali, Cameroon, and Nigeria
(2015-11)Snakebite envenoming causes a heavy toll in sub-Saharan Africa in terms of mortality and sequelae. In the West African savannah, the viperid Echis ocellatus is responsible for the vast majority of bites. In the last decades, ... -
Expansion of Aedes albopictus Skull in Costa Rica
(2010-06-01)A report of the Aedes albopictus expansion in Costa Rica is described as well as its epidemiological analysis. -
Experimental myonecrosis induced by the venoms of South American Micrurus (coral snakes)
(1992)Venoms from 11 taxa of Micrurus (coral snakes) from Brazil and Colombia were tested for myotoxic activity in mice. All venoms, except that of M. surinamensis, induced myotoxicity as judged by the increase in plasma creatine ... -
Experimental pathology of local tissue damage induced by Bothrops asper snake venom
(2009-12-01)Envenomations by Bothrops asper are often associated with complex and severe local pathological manifestations, including edema, blistering, dermonecrosis, myonecrosis and hemorrhage. The pathogenesis of these alterations ... -
Experimental pathophysiology of systemic alterations induced by Bothrops asper snake venom
(2009-12-01)Moderate and severe envenomations by the snake Bothrops asper provoke systemic alterations, such as systemic bleeding, coagulopathy, hypovolemia, hemodynamic instability and shock, and acute renal failure. Systemic hemorrhage ... -
Exploration of immunoglobulin transcriptomes from mice immunized with three-finger toxins and phospholipases A2 from the Central American coral snake, Micrurus nigrocinctus
(2017)Snakebite envenomings represent a neglected public health issue in many parts of the rural tropical world. Animal-derived antivenoms have existed for more than a hundred years and are effective in neutralizing snake venom ... -
Exploring low enthalpy geothermal energy in Costa Rica: A pilot project to improve tourism energy matrix efficiency
(2022-12)Geothermal energy has been an important and stable part of the renewal energy matrix of Costa Rica for more than 25 years. However, the exploitation has been centred in high enthalpy energy for electric power generation, ... -
Exploring the venom of the forest cobra snake: Toxicovenomics and antivenom profiling of Naja melanoleuca
(2017-01-06)A toxicovenomic analysis of the venomof the forest cobra, N. melanoleuca,was performed, revealing the presence of a total of 52 proteins by proteomics analysis. The most abundant proteins belong to the three-finger ... -
Exposure of a Tropical Soil to mg/kg of Oxytetracycline Elicits Hormetic Responses in the Catabolic Activities of its Microbial Community
(2011-04)Many farmers in developing countries protect their crops with oxytetracycline and fertilize their farmlands with manure from animals that received this drug as growth promoter. In this study, a tropical soil was exposed ... -
