Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections and hospitalization in infants young children. Here, we analyzed genetic diversity RSV using partial G gene sequences 84 RSV-A 78 RSV- B positive samples collected Seoul, South Korea, for 10 consecutive years, from 2010 to 2019. Our phylogenetic analysis revealed that strains were classified into either ON1 (80.9%) or NA1 (19.0%) genotypes. On other hand, RSV-B demonstrated diversified clusters...
Abstract Background Currently, SARS‐CoV‐2 RNA detection using real‐time reverse‐transcription PCR (rRT‐PCR) is the standard diagnostic test for COVID‐19 infection. Various rRT‐PCR assays are currently used worldwide, targeting different genes of SARS‐CoV‐2.

The Rh blood group D antigen is the most immunogenic of all antigens, next to ABO antigens. Anti-D immunization clinically important since it may cause clinical problems, such as severe hemolytic transfusion reactions and disease newborn. DEL an extremely weak variant that cannot be detected by basic serologic typing typed D-negative without absorption-elution techniques RHD genotyping. Of phenotype, (c.1227G>A) allelic common in Korea. phenotype has been considered carry only a few antigens...
Complex karyotype (CK) is associated with a poor prognosis in both acute myeloid leukemia (AML) and myelodysplastic syndrome excess blasts (MDS-EB). Transcriptomic analyses have improved our understanding of the disease risk stratification neoplasms; however, CK-specific gene expression signatures been rarely investigated. In this study, we developed validated signature. Differential analysis between CK non-CK groups using data from 348 patients AML MDS-EB four cohorts revealed enrichment...
