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, ...

For more than 100 years, antivenoms have been produced by traditional methods of immunization of large mammals with mixtures of snake venoms (World Health Organization, 2010 and Gutiérrez et al., 2011). With the introduction ...

The Epstein-Barr virus (EBV) has been detected in subsets of breast cancers. In order to elaborate on these observations, we quantified by real-time PCR (Q-PCR) the EBV genome in biopsy specimens of breast cancer tissue ...

Las plantas arvenses constituyen reservorios importantes para los trips, desde donde parten para infestar los diversos cultivos de importancia económica. Para conocer los tisanópteros presentes en las mismas se muestrearon ...

Phylogenetic analysis of the envelope gene sequence (E) of three isolated Dengue virus type 1 (DEN- 1) sequences from the Costa Rican 1993 epidemic was performed. All the strains fell into genotype V. Genotype V has grouped ...

Mutations in the gene coding for the skeletal muscle Cl− channel (CLCN1) lead to dominant or recessive myotonia. Here, we identified and characterized CLCN1 mutations in Costa Rican patients, who had been clinically diagnosed ...

Myotoxic phospholipases A2 of class II are commonly found in the venoms of crotalid snakes. As an approach to understanding their structure±activity relationship, diverse natural variants have been characterized ...
