Journal ArticleDOI
Preliminary Single-Center Canadian Experience of Human Normothermic Ex Vivo Liver Perfusion: Results of a Clinical Trial.
Mariusz Bral,Boris Gala-Lopez,David L. Bigam,Norman M. Kneteman,Andrew J. Malcolm,Scott Livingstone,Axel Andres,Juliet Emamaullee,Leslie James Russell,Constantin C. Coussios,Lori J. West,Peter J. Friend,A. M. J. Shapiro +12 more
TL;DR: A preliminary single‐center North American experience using identical NMP technology demonstrates feasibility as well as potential technical risks of NMP in a North American setting and highlights a need for larger, randomized studies.
Journal ArticleDOI
Insulin-heparin infusions peritransplant substantially improve single-donor clinical islet transplant success.
Angela Koh,Peter A. Senior,Abdul Salam,Tatsuya Kin,Sharleen Imes,Parastoo Dinyari,Andrew J. Malcolm,Christian Toso,Bo Nilsson,Olle Korsgren,A. M. James Shapiro +10 more
TL;DR: Peritransplant intensive insulin and heparin enhances islet transplantation outcomes likely related in part to mitigation of the effects of the instant blood-mediated inflammatory reaction, combined with islet rest and avoidance of inflammation.
Journal ArticleDOI
Beta Cell Death by Cell-free DNA and Outcome After Clinical Islet Transplantation.
Boris Gala-Lopez,Daniel Neiman,Tatsuya Kin,Doug O’Gorman,Andrew R. Pepper,Andrew J. Malcolm,Sheina Pianzin,Peter A. Senior,Patricia Campbell,Benjamin Glaser,Yuval Dor,Ruth Shemer,A. M. James Shapiro +12 more
TL;DR: In this paper, the 1-hour signal represents dead beta cells carried over into the recipient after islet isolation and culture, combined with acute cell death post infusion, and was also detected 24 hours posttransplant (8/37 subjects, 21.6%).
Journal ArticleDOI
IgY antiporcine endothelial cell antibodies effectively block human antiporcine xenoantibody binding.

TL;DR: It is shown that chicken IgY antibodies to α‐Gal antigen epitopes and to other porcine aortic endothelial cell (PAEC) antigens block human xenoreactive natural antibody binding to both Porcine and rat cardiac tissues and porcines kidney tissues, suggesting that avian IgYs could be of potential use in inhibiting pig‐to‐human xenograft rejection.
Journal ArticleDOI
Supplemental islet infusions restore insulin independence after graft dysfunction in islet transplant recipients.
Angela Koh,Sharleen Imes,Tatsuya Kin,Parastoo Dinyari,Andrew J. Malcolm,Christian Toso,A. M. James Shapiro,Peter A. Senior +7 more
TL;DR: Using current protocols, SII in the absence of exenatide results in impressive insulin-independence rates and the durability of insulin independence seems to be promising, however, a beneficial effect of exENatide should not be discounted until tested in randomized controlled studies.
