Whole-genome sequencing and analysis of two azaleas, Rhododendron ripense and Rhododendron kiyosumense.

DNA Res 2021 Sep;28(5)

Kazusa DNA Research Institute, Kisarazu, Chiba 292-0818, Japan.

To enhance the genomics and genetics of azalea, the whole-genome sequences of two species of Rhododendron were determined and analysed in this study: Rhododendron ripense, the cytoplasmic donor and ancestral species of large-flowered and evergreen azalea cultivars; and Rhododendron kiyosumense, a native of Chiba prefecture (Japan) seldomly bred and cultivated. A chromosome-level genome sequence assembly of R. ripense was constructed by single-molecule real-time sequencing and genetic mapping, while the genome sequence of R. kiyosumense was assembled using the single-tube long fragment read sequencing technology. The R. ripense genome assembly contained 319 contigs (506.7 Mb; N50 length: 2.5 Mb) and was assigned to the genetic map to establish 13 pseudomolecule sequences. On the other hand, the genome of R. kiyosumense was assembled into 32,308 contigs (601.9 Mb; N50 length: 245.7 kb). A total of 34,606 genes were predicted in the R. ripense genome, while 35,785 flower and 48,041 leaf transcript isoforms were identified in R. kiyosumense through Iso-Seq analysis. Overall, the genome sequence information generated in this study enhances our understanding of genome evolution in the Ericales and reveals the phylogenetic relationship of closely related species. This information will also facilitate the development of phenotypically attractive azalea cultivars.

[Risk management and postoperative infection control].

Nihon Geka Gakkai Zasshi 2010 May;111(3):143-8

Department of Surgery, NTT Medical Center, Tokyo.

Review of nine cases of judicial precedent on the issue of the postoperative infection in Japan indicates the following issues: indication of surgery; violation of informed consent; preventive measures against nosocomial infection during the preoperative period; cleanliness control during surgery; and treatment of postoperative infection. The most important yardstick for judgment is whether the provided treatment is conformed to the level of standard medical treatment available at the time. Therefore, we should be well versed in the standard postoperative infection treatment, particularly infection surveillance data and CDC standard precautions and related guidelines. Moreover, in each hospital, an infection control team should play an important role in infection control and prevention through preparing manuals and clinical paths incorporating precautions to ensure that the whole staff comply with the prescribed procedures.
