Comparación de pruebas utilizadas para el diagnóstico de aspergilosis invasiva en el laboratorio del Hospital Calderón Guardia de enero del 2019 a junio del 2020: ELISA para la detección de galactomanano y PCR en tiempo real
(2021-06-01)La aspergilosis invasiva (AI) permanece en los últimos años como la principal causa de muerte por enfermedad fúngica invasiva (Pemán & Salavert, 2012). El diagnóstico definitivo de la AI se realiza por medio de una biopsia ... -
Comparación entre inmunización pasiva e inmunización activa como procedimiento para controlar los envenenamientos producidos por la serpiente Bothrops asper (terciopelo) en un modelo canino
(2020)Los accidentes ofídicos en animales domésticos son un problema importante para la garantía del bienestar animal en Costa Rica. En este trabajo se comparó la inmunización pasiva por administración de antivenenos con la ... -
Comparative biochemical characterization of Viperidae snake venoms from Perú reveals two compositional patterns of phospholipase A2 expression
(2020)Snake species within the Bothrops complex (sensu lato) are of medical relevance in Latin America, but knowledge on their venom characteristics is limited, or even unavailable, for some taxa. Perú harbors 17 species of pit ... -
Comparative proteomic analysis of the venom of the taipan snake, Oxyuranus scutellatus, from Papua New Guinea and Australia: Role of neurotoxic and procoagulant effects in venom toxicity
(2012-04-03)The venom proteomes of populations of the highly venomous taipan snake, Oxyuranus scutellatus, from Australia and Papua New Guinea (PNG), were characterized by reverse-phase HPLC fractionation, followed by analysis of ... -
Comparative study of synthetic peptides corresponding to region 115-129 in Lys49 myotoxic phospholipases A2 from snake venoms
(2003)Lys49 phospholipase A2 homologues constitute a group of catalytically-inactive proteins, present in the venoms of many crotalid snakes, which induce myonecrosis. Current evidence supports the mapping of their toxic site ... -
Comparative study of the cytolytic activity of snake venoms from African spitting cobras (Naja spp., Elapidae) and its neutralization by a polyspecific antivenom
(2011-11)Venoms of several Naja species found in Sub-Saharan Africa, and commonly known as "spitting cobras", induce a predominantly cytotoxic pattern of envenomings that may evolve into tissue necrosis and gangrene. Cytotoxic ... -
Comparative study of the efficacy and safety of two polyvalent, caprylic acid fractionated [IgG and F(ab0)2] antivenoms, in Bothrops asper bites in Colombia
(2012-02)The efficacy and safety of two polyvalent horse-derived antivenoms in Bothrops asper envenomings were tested in a randomized, double-blind, clinical trial performed in Colombia. Both antivenoms were manufactured from the ... -
Comparative study of the venoms of three subspecies of Lachesis muta (bushmaster) from Brazil, Colombia and Costa Rica
(1998-12)A comparative study was performed on the pharmacology and biochemistry of venoms from three subspecies of Lachesis muta (L. m. stenophrys, L. m. muta and L. m. rhombeata) from Brazil, Colombia and Costa Rica. All venoms ... -
Comparative study on coagulant, defibrinating, fibrinolytic and fibrinogenolytic activities of Costa Rican crotaline snake venoms and their neutralization by a polyvalent antivenom
(1989)The coagulant, defibrinating, fibrino lytic and fibrinogenolytic activities of venoms from ten species of Costa Rican crotaline snakes were studied, together with the neutralization of these effects by a polyvalent antivenom. ... -
Comparative study on the ability of IgG and F(ab')2 antivenoms to neutralize lethal and myotoxic effects induced by Micrurus nigrocinctus (coral snake) venom
(1999-08)A comparative study was performed on the ability of IgG and F(ab')2 antivenoms to neutralize lethal and myotoxic activities of Micrurus nigrocinctus venom. Both antivenoms were adjusted to a similar neutralizing potency ... -
Comparative study on the ability of IgG and Fab sheep antivenoms to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper (terciopelo) snake venom
(2000-02)The ability of sheep antivenoms, consisting of whole IgG molecules or Fab fragments, to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper venom was comparatively studied in mice. The two antivenoms ... -
Comparison between IgG and F(ab′)2 polyvalent antivenoms: neutralization of systemic effects induced by Bothrops asper venom in mice, extravasation to muscle tissue, and potential for induction of adverse reactions
(2001-06)Whole IgG and F(ab′)2 equine-derived polyvalent (Crotalinae) antivenoms, prepared from the same batch of hyperimmune plasma, were compared in terms of neutralization of the lethal and defibrinating activities induced by ... -
