https://www.selleckchem.com/products/kynurenic-acid.html Continuing medical education (CME) is the essential basis for student teaching and for training and further development of physicians. Without it, modern and adequate patient care is unthinkable. Recently, the coronavirus pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARSCoV2), forced the entire medical community to change its usual habits of advanced medical training, teaching and learning. As a result, digital training and teaching via social media, online medical encyclopedias, web-based learning platforms and educational podcasts moved to the fore. Here, we give an overview on current concepts for online medical education, with special consideration of dermatology.The dissemination and abundances of Vibrio species in aquatic environments are of interest, as some species cause emerging diseases in humans and in aquatic organisms like fish. It is suggested that Vibrio cholerae non-O1 infections of Plecoglossus altivelis ('ayu') were spread to various parts of Japan through the annual transplantation of juvenile fish. To investigate this, we used genome-aided tracing of 17 V. cholerae strains isolated from ayu between the 1970s and 1990s in different Japanese freshwater systems. The strains formed a genomic clade distinct from all known clades, which we designate as the Ayu clade. Two clonal genomic groups identified within the clade, Ayu-1 and Ayu-2, persisted for a few years (between 1977 to 1979 and 1987 to 1990, respectively), and clonal replacement of Ayu-1 by Ayu-2 took place over an 8-year period. Despite the high similarity between Ayu-1 and Ayu-2 (> 99.9% identity and > 97% fraction of genomes shared), differences in their gene repertoires were found, raising the possibility that they are phenotypically distinct. These results highlight the importance of genome-based studies for understanding the long-term dynamics of populations over the timescale of years.Metal carbenes p
