(2016-03-01)Bothrops jararaca is a slender and semi-arboreal medically relevant pit viper species endemic to tropical and subtropical forests in southern Brazil, Paraguay, and northern Argentina (Misiones). Within its geographic range, ... -
Combustibles forestales superficiales y riesgo de incendio en dos estadios de sucesión secundaria y bosques primarios en el Parque Nacional Palo Verde, Costa Rica
(2015-06-22)Se cuantificó el combustible forestal superficial de los árboles en pie y del mantillo orgánico. También, se caracterizó la composición florística, en tres tratamientos de estadios sucesionales, de 10-25 años (29,88 ha) ... -
Community richness of amphibian skin bacteria correlates with bioclimate at the global scale
(2019)Animal-associated microbiomes are integral to host health, yet key biotic and abiotic factors that shape host-associated microbial communities at the global scale remain poorly understood. We investigated global patterns ... -
Comparación de dos tubos de extracción de sangre en la determinación bioquímica de 21 analitos: tubo con gel separador Hongyu Medical® y tubo sin gel separador Vacuette®
(2020-12-16)Algunos componentes de los tubos de extracción de sangre pueden generar interferencia en los análisis rutinarios, de ahí la importancia de validar dichos materiales antes de ser implementados en el uso clínico. Se realizó ... -
Comparación de los resultados obtenidos en el Panel de Neumonía Filmarray® de BIOFIRE®, el Gram y el cultivo bacteriano, en muestras de aspirado de tubo endotraqueal, provenientes de pacientes críticos con COVID-19, en el Hospital México del 2020 al 2021
(2023)La neumonía es una enfermedad del tracto respiratorio inferior que puede tener como agente etiológico diferentes microorganismos. Dentro de las neumonías nosocomiales, se encuentra la neumonía asociada a la ventilación ... -
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 ... -
