The 22nd IUNS-ICN was scheduled to be held from September 14-19, 2021 in Tokyo, Japan. In view of the worldwide spread of the COVID-19 pandemic, the organisers of ICN have been carefully monitoring its impact.  Due to its developing situation and difficulties in travelling abroad, after much thought and deliberation, the Organizing Committee of 22nd IUNS-ICN has decided to postpone the congress to December 6-11, 2022. This was a difficult decision to make; however, the health and safety of the participants are of the highest priority.  

Since the Congress has been postponed, the call for abstracts is temporarily suspended. New important dates and any possible changes will be circulated in due time.
