Poster creation
The poster was designed and produced May 1992 on a Macintosh computer using MacDraw II (with bar graphs from Cricket Graph) and printed landscape across a chain of several sheets of paper using the Imagewriter dotmatrix printer.
For this 2024 remastered poster below, the 1992 MacDraw II file was converted and edited using LibreOffice Vanilla, and next Pixelmator Pro was used for additional ‘repair’ (conversion issues with the many layers used for ‘tubes’ creation) and the insertion of the photo scans.

Percoll UWS Pancreatic Islet Purification (20240731) now has a remastered poster image , see below.
Lyon 1991 Percoll Poster | 20240731 • 20240808
20240808 – remastered poster : 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.
The 20240731 post now has this updated 20240808 – poster image.

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.
Here the remastered 20240804 edition of that Minneapolis 1989 poster presentation.
A previous edition of the remastered poster was published here two years ago (2) but that edition had a different photo print (higher magnification, and without the bar indicator) of the purified islet preparation inserted, not the original image. This has been corrected now. In addition the original line spacing is now restored.

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.

7. Pentastarch is the synthetic colloid component of UWS (ViaSpan / Belzer solution), a purified fraction (250 kD) of hydroxyethyl starch. Pentastarch powder was used here to increase the Pentastarch concentration and density of the UWS.

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.

The dissertation ‘Pancreatic islet transplantation’ was published first as a paperback in 1994 ( ISBN paperback 9789080216419 ) — and obviously that is considered virtually inaccessible in this digital age. Though it is still available ‘new’ — collectors item ;)
Last October the digital edition ISBN eBook (pdf) 9789080216402 has been produced and first released by the author / publisher Michel van der Burg at Miracles•Media as a free download , available from October 25th, 2022.

Free download available now of the Addendum e-book (pdf) ‘Propositions | Stellingen (dutch)’ belonging to the dissertation ‘Pancreatic islet transplantation’ by Michel P.M. van der Burg (addendum eBook ISBN 9789080216402) .
Note : The Dutch dissertation system has a tradition of accompanying the generally very specialised PhD thesis with ten or more propositions (other ‘theses’), that should be ‘defensible’, and while at least some should be related to the dissertation, others generally reflect the PhD candidate’s broader interests, and the last one is often playful.
