The proceedings paper delivered at the 4th IPITA is included below in the Notes , as well as references of the related full papers and related chapters of PhD thesis.

This IPITA meeting in Amsterdam was also a good opportunity to catch up with colleague Nick London (see photo) from the Leicester (UK) group discussing our Leiden and Leicester islet isolation work using the University of Wisconsin organ preservation solution (UWS). The Leicester group were one of the first groups to examine and adopt our novel method of islet isolation in UWS.
Several groups reported at this 4th IPITA symposium on the effects of using (modified) UW solution (UWS) during islet isolation : Leicester (pig, human islets), Oxford (rat, rabbit islets), Minneapolis (human islets), Paris, and Giessen (clinical human allo islet transplantation).

During the 4th IPITA I discussed in detail the rationale of our UWS work, the important components of UWS, and basal solution for islet purification (Percoll-UWS) with Yoko Mullen (in particular) and her co-worker Charles Brunicardi (see photo) of the UCLA Islet Transplant Team (LA, USA)…contributing to the development of Yoko’s Los Angeles preservation solution #1 (LAP-1) patented in 1997 (see Notes, US5679565A).

The official founding meeting of the IPITA was actually at this 4th International Congress on Pancreas and Islet Transplantation — June 27–30, 1993 in Amsterdam (The Netherlands) hosted by Dr. Reinout van Schilfgaarde (see photo).

Below some of the photos I took during a break at the 4th IPITA in Amsterdam, near the Rijksmuseum (corner Spiegelgracht / Tweede Weteringdwarsstraat) , and at the congress venue (RAI Amsterdam).
