Elapid venom toxins: multiple recruitments of ancient scaffolds
(1999-01)
Nigroxins A and B, two myotoxic phospholipases A2 (PLA2s) from the venom of the American elapid Micrurus nigrocinctus, belong to a new PLA2 subclass. Their primary structures were established and compared with those of ...
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, ...
Local tissue damage induced by BaP1, a metalloproteinase isolated from Bothrops asper (Terciopelo) snake venom
(1995-12)
The pathogenesis of hemorrhage and other local effects induced by the metalloproteinase BaP1, isolated from Bothrops asper venom, was investigated using various in vivo and in vitro models. Upon intramuscular injection in ...
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 ...
Comprendiendo los venenos de serpientes: 50 años de investigaciones en América Latina
(2002)
As a tribute to Revista de Biología Tropical in its 50th anniversary, this review describes some of the main research efforts carried out in the study of the chemical composition and the mechanism of action of toxins present ...
Understanding structural and functional aspects of PII snake venom metalloproteinases: Characterization of BlatH1, a hemorrhagic dimeric enzyme from the venom of Bothriechis lateralis
(2014-06)
A new homodimeric PII metalloproteinase, named BlatH1, was purified from the venom of the Central American arboreal viperid snake Bothriechis lateralis by a combination of anion-exchange chromatography, hydrophobic interaction ...
Degradation of UV filters in sewage sludge and 4-MBC in liquid medium by the ligninolytic fungus Trametes versicolor
(2012-08-15)
Ultraviolet (UV) filters are xenobiotic compounds that can enter the environment through the liquid
effluent of wastewater treatment plants (WWTPs) and through adsorption in the sludge by-product
because of their high ...
