Activation of the lytic program of the Epstein–Barr virus in Burkitt's lymphoma cells leads to a two steps downregulation of expression of the proapoptotic protein BimEL, one of which is EBV-late-gene expression dependent
(Virology 387 (2009) (1) p.41.49, 2009-02-28)The Epstein–Barr virus (EBV) generally latently infects its target cells with expression of genes conferring resistance to apoptosis. However, the modulation of apoptotic signals during lytic cycle remains poorly understood. ... -
Analysis of mutational dynamics at the DMPK (CTG)n locus identifies saliva as a suitable DNA sample source for genetic analysis in myotonic dystrophy type 1
(2019-05)Genotype-to-phenotype correlation studies in myotonic dystrophy type 1 (DM1) have been confounded by the age-dependent, tissue-specific and expansion-biased features of somatic mosaicism of the expanded CTG repeat. Previously, ... -

Anthropogenic activities and the problem of antibiotic resistance in Latin America: a water issue
(2021)Antibiotics revolutionized modern medicine and have been an excellent tool to fight infections. However, their overuse and misuse in different human activities such as health care, food production and agriculture has ... -
Anti-rotavirus antibody in human colostrum
(The Lancet 311(8054), 7 January 1978, Pages 39–40. Originally published as Volume 1, Issue 8054, 1978)During investigation of the epidemiology of human rotavirus infection in Costa Rica, the anti-human rotavirus capacity of colostrum was studied. We were looking for an explanation for the relatively low incidence of acute ... -
Anticuerpos IgE específicos de alergenos comunes en niños costarricenses
(Alergia, Asma e Inmunología Pediátricas :13 (2); p 40-43, 2004-05)La morbilidad por asma y otras enfermedades alérgicas aumentan cada año y un factor muy importante es la exposición a niveles elevados de alergenos interiores. En el presente estudio se evaluó la prevalencia y la exposición ... -
Aseguramiento y control de calidad en la producción de medios de cultivo microbiológicos
(2017)El aseguramiento y control de calidad de los medios de cultivo que se utilizan para las labores de microbiología, debe ser eje central para establecer la calidad de todos los anàlisis que se ligan a su utilización. Se ... -
Asociación del polimorfismo del codon 72 del gen P53 con el riesgo de cáncer gástrico en una población de alto riesgo de Costa Rica
(Revista de Biología Tropical 53 (3-4): 317-324, 2005, 2005-10-03)El cáncer gástrico es la segunda causa de muerte por cáncer en el mundo. Varios factores han sido asociados con el riesgo de llegar a desarrollarlo, entre ellos la predisposición genética. El gen p53 presenta un polimorfismo ... -
Avances en el conocimiento de la diarrea viral
(Infectología 2:151-160, 1981)Hasta la segunda década de este siglo, la diarrea había encabezado las causas de muerte durante el primer año de vida, aún en los países desarrollados; en estas naciones, tal problema y sus complicaciones disminuyó ... -
Bacterial communities in residential wastewater treatment plants are physiologically adapted to high concentrations of quaternary ammonium compounds
