Following first introduction of the use UWS (the UW organ preservation solution) for pancreatic islet isolation in 1989 , next also purification of the islets in UWS was presented in 1991, with two options.
One option was an iso-osmotic density gradient solution of Percoll in UWS. The second option was a density gradient solution created by increasing the Pentastarch concentration in UWS (7) . Note that Pentastarch is a component of UWS.
The Percoll-UWS poster was posted recently (8)
Here the remastered poster presentation on Pentastarch-UWS :
Pentastarch in UW (SUW): a new method for complete islet purification. 3rd International Congress on Pancreatic and Islet Transplantation, Symposium on Artificial Insulin Delivery System, Lyon (France) June 6–8, 1991.
The poster was designed and produced on my personal Macintosh computer and Imagewriter dotmatrix printer, the night of June 3-4, 1991, using the MacDraw II application.
The Apple Imagewriter-II matrix printer, allows printing landscape across a chain of several sheets of paper, strips, the width of the poster (here 3 sheets long). The strips of the poster (here 3 strips) were then glued on site along the perforation, creating the 36/24 inch poster.
Finally the photo print of the purified islets was pasted in the poster at the spot at the venue in Lyon. In Lyon a photo of a dithizone stained Pentastarch purified islet sample was shown. To save time the archive was not searched for that image, and another image of Pentastarch purified islets was inserted in this remastered edition, a reflection contrast micrograph of an ultrathin section of Pentastarch purified islets immuno-stained with gold on insulin in the islet cells.
Nowadays, it is a challenge opening such old Mac files … Luckily, I was able to open this MacDraw II poster file in LibreOffice Vanilla and now learned to use the app to further correct most conversion issues. Pixelmator Pro was used for additional ‘repair’ and insertion of the photo scan.

The poster was designed and produced on my personal Macintosh computer and Imagewriter dotmatrix printer, the night of June 3-4, 1991, using the MacDraw II application, inserted with a bar graph prepared in the Cricket Graph app. The Apple Imagewriter-II matrix printer, allows printing landscape across a chain of several sheets of paper, strips, the width of the poster (here 3 sheets long). The strips of the poster (here 5 strips) were then glued on site along the perforation, creating a 36/41 inch poster. Finally the RCM photo print of the purified human islets was pasted in the poster at the spot at the venue in Lyon.
Nowadays, it is a challenge opening such old Mac files … Luckily, I was able to open this MacDraw II poster file in LibreOffice Vanilla (open source app) with nice results. Only minor issues appeared with text spacing of the top row of the table , and the caption in the photo section. Some color is showing in the graphs , not evident on my grayscale equipment in the 90s. …. The poster image of 20240731 has been replaced by a remastered image , see Note Update 20240808 below.

Following the first publication here last month (20240731) of the original 1991 MacDraw poster opened (converted) in LibreOffice Vanilla (1), I learned how to do some editing in the LibreOffice app to further restore poster layout details such as line spacing, and font style. An archive photo of another poster presentation in Pittsburgh in 1992 (that will be posted here soon) guided this restoration.
Current workflow : 1) opening the MacDraw II file in LibreOffice Vanilla 2) editing in in LibreOffice Vanilla , saving as LibreOffice Vanilla file (OpenDocument Drawing – extension odg). 3) opening the photo tiff image in the Mac’s Preview app, and copying the displayed image to the clipboard 4) pasting the clipboard image in the LibreOffice doc , and dragging to adjust size and location 5) exporting the file as PDF (image resolution 300 DPI ; PDF/A-1b ; PDF/UA). 6) Converting the PDF in the Preview app to TIFF 144 pixels/inch. 7) Adding caption , metadata etc with JPEG conversion in PhotoMill.
This 20240731 post now has this updated 20240808 – poster image.

The 9th Annual International Congress of the PEN Club — Poets, Essayists, Novelists — in 1931 in the townhall of Rotterdam, Holland, with a focus on the Flemish writer Felix Timmermans, Dutch writer Dirk Coster (?), Dutch poet P.C. Boutens, Dutch writer Anthonetta (Top) Naeff, and in the final scene : the English author John Galsworthy (Nobel Prize Literature 1932) talking with the Dutch journalist and writer Lord Jan Feith, and the French author, critic and literary historian Benjamin Crêmieux — secretary of the French section of the PEN Club (see below).
From its inception in 1921, PEN was intended to be a non-political organisation. However, with the rise of the Nazis in Germany, and of fascism in Spain and Italy, it became increasingly difficult for PEN to stay away from the political; and that year 1931, the PEN Committee made a public ‘Appeal to All Governments’, which protested the plight of those imprisoned for political or religious reasons.
In 1940 Benjamin Crêmieux joined the French underground and became a leader of the Maquis resistance fighters. In April 1943, two Gestapo agents detained Crémieux in Marseilles. He was arrested, imprisoned, and deported to Nazi Germany, where, in April 1944 he was executed in the Buchenwald concentration camp.

Lancet Letter 1989 UW Solution Islet Isolation | 20220823 | Michel van der Burg | michelvanderburg•com | June 1989 preparing first submission for publication as letter in the Lancet medical journal the new concept of using the UW solution ( the University of Wisconsin organ preservation solution) for isolation and complete purification of islets of Langerhans in the laboratory for transplantation in diabetic patients. Later that year that exciting discovery was presented at meetings in Minneapolis, USA, and Barcelona, Spain. Details in yesterday’s post. Submission for publication as a letter in the Lancet had had no succes 😉
Final draft text produced on my personal Macintosh ED and Imagewriter-II matrix printer with Geneva font.
September 1989 at a symposium of two international societies in Minneapolis, USA (1) , I presented this first poster on the ‘ invention ‘ of using the UW solution ( the University of Wisconsin organ preservation solution) during pancreatic islet isolation, with the exciting discovery of near-complete purification of islets of Langerhans in the laboratory for transplantation in diabetic patients.
The next month at a meeting in Barcelona, Spain, this rather radical new concept was introduced (2, 3). June 1989 submission for publication as a letter in the Lancet had had no succes 😉
Poster designed and produced on my personal Macintosh ED and Imagewriter-II matrix printer, allowing full width printing over multiple pages in landscape (a low cost do-it-yourself discovery by me, at a time when posters were prepared on poster boards by graphical professionals using photography and special lettering techniques for around $400). Original MacDraw II file conversion with LibreOffice Vanilla.

Updates
20240804 – This remastered 20240804 edition of the Minneapolis 1989 poster , now shows the original photo of the islet prep as posted at the meeting in 1989. In addition the correct line spacing is now restored. The previous poster published online two years ago (20220822) showed a different photo print (higher magnification, and without the bar indicator) of the same islet prep, not the correct image.
