A new method for the detection of phospholipase A2 variants: identification of isozymes in the venoms of newborn and adult Bothrops asper (terciopelo) snakes
(1988)A new method for the identification of phospholipase A2 isozymes in snake venoms is described. The technique is based on the separation of the venom components by isoelectric focusing in agarose gels, transfer of the protein ... -
Aging of biomixtures: Effects on carbofuran removal and microbial community structure
(2017)The aim of this work was to determine the efficiency of a straw/compost/soil biomixture for pesticide depuration during its aging and continuous use, for a period of over a year, based on its capacity to remove carbofuran ... -
An electrophoretic study on phospholipase A2 isoenzymes in the venoms of Central American crotaline snakes
(1992)The number and isoelectric points of phospholipase A2 isoenzymes were studied in the venoms of 12 Central American crotaline snakes of the genera Bothrops, Crotalus, Lachesis and Agkistrodon. The study was carried out by ... -
Ant microbial symbionts are a new model for drug discovery
(2019)Ants have been widely studied, with 14,000 described species, but it is not until recently that they gained attention as sources for antimicrobial drug discovery. An increasing amount of studies are investigating ant-microbe ... -
Aplicación del método de coagulación de plasma al estudio ultraestructural de especímenes biológicos
(1991)Biological particulate specimens, including Saccharomyces cerevisiae yeast, bovine spermatozoa and human blood cells (normal erythrocytes and leukemic cells) were processed for scanning and transmission electron microscopy ... -
Avances de la bioinformática en Costa Rica: Vista retrospectiva y perspectivas
(2021-11-09)Introducción: La disciplina científica de la bioinformática tiene el potencial de generar aplicaciones innovadoras para las sociedades humanas. Costa Rica, pequeña en tamaño y población en comparación con otros países de ... -
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 ... -
Degenerative and regenerative changes in murine skeletal muscle after injection of venom from the snake Bothrops asper: a histochemical and immunocytochemical study.
(1991)The degenerative and regenerative changes in murine skeletal muscle after injection of Bothrops asper venom were studied by histological, lectin histochemical and immunocytochemical techniques. According to our observations, ... -
Derived proteins from cry genes of bacillus thuringiensis
(2018-10-15)Combinations of Bacillus thuringiensis (Bt) proteins and nucleic acids encoding these Bt proteins are disclosed. Plants transformed with nucleic acids encoding these Bt proteins are also disclosed -
DNase activity in Costa Rican crotaline snake venoms: quantification of activity and identification of electrophoretic variants.
(1991)DNase activity of Costa Rican crotaline snake venoms from the genera Bothrops, Crotalus and Lachesis was quantified by an enzymodiffusion method on agarose/DNA gels containing ethidium bromide. The reaction is detected as ... -
ENSO‐Influenced Drought Drives Methane Flux Dynamics in a Tropical Wet Forest Soil
(2019)Global atmospheric methane growth rates have wildly fluctuated over the past three decades, which may be driven by the proportion of tropical land surface saturated by water. The El Niño/Southern Oscillation Event (ENSO) ... -
First characterization of the probiotic potential of lactic acid bacteria isolated from Costa Rican pineapple silages
(2021)Background. Agro-industrial waste from tropical environments could be an important source of lactic acid bacteria (LAB) with probiotic potential. Methods. Twelve LAB isolates were isolated from pineapple silages. The ... -
Gene expression analyses of gingival tissue of patients with periodontitis using public transcriptomic data
(2022-11)Abstract—Periodontal disease (PD) is a multifactorial and chronic condition of infection and inflammation of the gingival tissue. However, many of the biological and molecular mechanisms regarding the development of this ... -
Gene Expression Dynamics Induced by Ciprofloxacin and Loss of LexA Function in Pseudomonas aeruginosa PAO1 Using Data Mining and Network Analysis
(2018)Pseudomonas aeruginosa is an opportunistic pathogen that causes a variety of infections in humans and frequently develops mechanisms of resistance to antibiotics, which makes its treatment difficult. In this study we ... -
High quality 3C de novo assembly and annotation of a multidrug resistant ST-111 Pseudomonas aeruginosa genome: Benchmark of hybrid and non-hybrid assemblers
(2020)Genotyping methods and genome sequencing are indispensable to reveal genomic structure of bacterial species displaying high level of genome plasticity. However, reconstruction of genome or assembly is not straightforward ... -
Pathological changes induced by BaH1, a hemorrhagic proteinase isolated from Bothrops asper (Terciopelo) snake venom, on mouse capillary blood vessels
(1994-08)The pathological changes induced in capillaries by BaH1, a hemorrhagic metalloproteinase isolated from the venom of Bothrops asper, were studied after i.m. injection in mouse gastrocnemius. Hemorrhage was observed ... -
Phylogenetic analyses of antibiotic-producing Streptomyces sp. isolates obtained from the stingless-bee Tetragonisca angustula (Apidae: Meliponini)
(2019)Many insects have been associated with actinobacteria in protective symbiosis where antimicrobial metabolites inhibit host pathogens. However, the microbiota of neotropical insects such as the stingless-bee Tetragonisca ... -
Population Genomics Insights into Adaptive Evolution and Ecological Differentiation in Streptomycetes
(2019)Deciphering the genomic variation that represents microevolutionary processes toward species divergence is key to understanding microbial speciation, which has long been under debate. Streptomycetes are filamentous bacteria ... -
