is a cosmopolitan aquatic plant genus that includes species with widespread global distributions. In previous studies, a revised molecular phylogeny was inferred using seven plastid loci from nine species across different geographic regions. By utilizing complete organellar genomes, we aim to provide a more comprehensive dataset that offers a robust phylogenetic signal for resolving species evolutionary relationships.

Although some population and genetic analyses have been conducted for this species, no extensive comparisons of genetic variation from plastomes have yet been investigated.
Methods: We assembled a total of 322 complete plastomes in this study and did a series of comparative analyses to better resolve pan-plastomic patterns of .
Background/aims: As the number of colonoscopies and polypectomies performed continues to increase in many Asian countries, there is a great demand for surveillance colonoscopy. The aim of this study was to investigate the adherence to postpolypectomy surveillance guidelines among physicians in Asia.
Methods: A survey study was performed in seven Asian countries.
Background/aims: The clinical practice pattern of polypectomy is not well-investigated in Asian countries. We aimed to survey Asian endoscopists about their preferred polypectomy techniques for given conditions and images of polyps.
Methods: A survey was performed using questionnaires composed of two parts: a scenario-based questionnaire using scenarios of polyps, which were adopted from the European Society of Gastrointestinal Endoscopy guidelines, and an image-based questionnaire using provided endoscopic images of polyps.
