The dystrophinopathies in Costa Rica
(Rev Biol Trop 52(3), 2004, 2004)
A five-years long study aiming to describe the basic genetic epidemiology of the dystrophinopathies in Costa Rica recruited 31 patients with clinical symptoms of DMD/BMD at the National Children’s Hospital (HNN). This ...
Micronúcleos y otras anormalidades nucleares en el epitelio oral de mujeres expuestas ocupacionalmente a plaguicidas
Micronuclei and other nuclear abnormalities in the oral epithelium of female workers exposed to pesticides
(Revista de Biología Tropical 52(3) p. 611 -621, 2004-12-15)
In order to study if banana fields labour exposure to pesticides produces some kind of DNA damage,
we determine the presence of micronuclei in epithelial oral cells in working women in Guapiles and
Siquirres, Costa Rica, ...
Las mutaciones inestables, nuevo reto para el consejo genético de enfermedades hereditarias
Unstable mutations, new challenges for genetic counseling of inherited disorders
(Revista de Biología Tropical 52 (3) 491-499, 2004)
Las mutaciones inestables constituyen un tipo de alteración genética descubierta en Ia década de los noventa. En condiciones normales, regiones especificas de los genes estan constitudas por repeticiones de una aucencia ...
Expression of the rice hoja blanca virus (RHBV) non-structural protein 3 (NS3) in Escherichia coli and its in situ localization in RHBV-infected rice tissues
(Universidad de Costa Rica, 2004)
The non-structural NS3 protein gene from the rice hoja blanca virus (RHBV) was fused to the glutathione- S-transferase carboxilic end and expressed in Escherichia coli strain JM83. Large quantities of fusion protein were ...
Aberraciones cromosómicas en trabajadoras expuestas a plaguicidas
Chromosomic aberrations in female workers exposed to pesticides
(Revista de Biología Tropical 52(3) p.623-628, 2004-12-15)
The purpose of this work was
to determine if the occupational exposure to those pesticides used at banana plantations’ packaging plants produces
genetic damage to somatic cells of female workers. Chromosomal aberrations ...

The SIR (A.AAAT). within intron 1 of the TP53 Locus was screened in 17 populations from 3 main
ethnic groups: Europeans, Asiatics, and Africans. and from the hybrid population of Costa Rica (1968 samples).
Three alleles, ...
