[Gene expression analysis in myocytes of right atrial appendages in patients with atrial fibrillation using cDNA microarray technique].

Gene expression level of 2900 genes was studied by cDNA microarray in patients with atrial fibril-lation (AF) or sinus rhythm. Gene transcripts were analysed in samples of right atrial appendages from 47 patients undergoing surgery for valve repair or coronary artery bypass. Standard correlation analysis and two dimensional hierarchical clustering were used for study of differentially expressed genes in patient groups.

[Human chromosome 2: database of cytogenetic mapping and phenotypical characteristics of structural aberrations].

A data retrieval system CHRODYS combines databases on autosomal human dysmorphism. This system is based on the reported case descriptions of patients from our practice in 1970s-1990s. The system CHRODYS differs from similar systems by strict selection of data on partial and complete autosomal trisomies and monosomies for cytogenetic parameters.
