Integration and Fixation Preferences of Human and Mouse Endogenous Retroviruses Uncovered with Functional Data Analysis
Endogenous retroviruses (ERVs), the remnants of retroviral infections in the germ line, occupy ~8% and ~10% of the human and mouse genomes, respectively, and affect their structure, evolution, and function. Yet we still ...
Characterization of Batrachochytrium dendrobatidis Inhibiting Bacteria from Amphibian Populations in Costa Rica
Global amphibian declines and extinction events are occurring at an unprecedented rate. While several factors are responsible for declines and extinction, the fungal pathogen Batrachochytrium dendrobatidis (Bd) has been ...
IVF in Costa Rica
For 16 years, Costa Rica was the only country in the world that banned IVF, after it had been successfully conducted from 1995 to 2000. It also has been the only country that banned IVF based on the argument that it protects ...
Efecto de extractos de artrópodos sobre la multiplicación del Toxoplasma gondiidentro de macrófagos peritoneales de ratón
(Rev. Biol. Trop. 51(2): 317-320, 2003, 2003)
Treatment of toxoplasmosis usually causes secondary effects. It is important to find active substances extracted from natural organisms. In this work we studied some arthropod extracts that have effect against Toxoplasma ...
Distribution and reproduction of Ambidexter panamense and Palaemonetes schmitti in Pacific Costa Rica (Crustacea, Decapoda)
Este constituye el primer registro de las especies de carídeos P. schmitti y A. panamense para Costa Rica. Adultos de ambas especies fueron colectados en el estero de Punta Morales, Golfo de Nicoya, de enero a diciembre ...
Phylogenetic analysis of ITS data from endophytic fungi using massive parallel bayesian tree inference with exabayes
Análisis filogenético de secuencias ITS provenientes de hongos endófitos utilizando inferencia bayesiana paralela de árboles con exabayes
Ecological studies of fungal communities have been favored thanks to the emergence and improvement of independent culture techniques that use the ITS region as a molecular marker. This has allowed a more accurate identification ...
Distribución del psílido asiático de los cítricos (Diaphorina citri Kuwayama) en Costa Rica
Distribution of Diaphorina citri Kuwayama in Costa Rica
El insecto plaga Diaphorina citri es vector de la enfermedad de los cítricos conocida como “Huanglongbing”. Esta enfermedad, causada por una bacteria limitada al floema, llamada Candidatus Liberibacter, es de gran importancia ...
Brain structure–function associations in multi-generational families genetically enriched for bipolar disorder
Recent theories regarding the pathophysiology of bipolar disorder suggest contributions of both neurodevelopmental and neurodegenerative processes. While structural neuroimaging studies indicate disease-associated ...
Key to the species of the genus Scleria (Cyperaceae) in Costa Rica based on the morphology of achenes
We described the achenes of 21 species of the genus Scleria reported in Costa Rica using 16 morphological characters and developed a key based only on achene characteristics. Specimens deposited in herbaria in Costa Rica ...
A microbial consortium from a biomixture swiftly degrades high concentrations of carbofuran in fluidized-bed reactors
An on-farm biopurification system (BPS) biomixture, with proven capacity to degrade carbofuran (CBF) was used as inoculum for a selective-enrichment process to obtain a bacterial consortium capable of using CBF as a sole ...
