Appa H, et al. Among authors: human p. Front Cardiovasc Med. 2022 Mar 3;9:791949. doi: 10.3389/fcvm.2022.791949. eCollection 2022. Front Cardiovasc Med. 2022. PMID: 35310972 Free PMC article.
High glutaraldehyde concentrations reduce rather than increase the calcification of aortic wall tissue.
Zilla P, Weissenstein C, Bracher M, Zhang Y, Koen W, Human P, von Oppell U. Zilla P, et al. Among authors: human p. J Heart Valve Dis. 1997 Sep;6(5):502-9. J Heart Valve Dis. 1997. PMID: 9330172
Two animal models were compared: subcutaneous implantation in rats (12 weeks) and vascular implantation in non-human primates, Chacma baboons (six weeks). RESULTS: In both animal models the highest level of calcification was found in the group with delayed fixation in 0.2% …

Stentless bioprosthetic heart valve research: sheep versus primate model.
Trantina-Yates A, Weissenstein C, Human P, Zilla P. Trantina-Yates A, et al. Among authors: human p. Ann Thorac Surg. 2001 May;71(5 Suppl):S422-7. doi: 10.1016/s0003-4975(01)02502-4. Ann Thorac Surg. 2001. PMID: 11388240
RESULTS: The main difference between the two animal models was in aortic wall calcification (64.8+/-39.8 microg/mg in the sheep model versus 4.1+/-5.9 microg/mg in the primate model; p > 0.005). In both models, leaflet calcification was negligible (2.6+/-2.4 microg/mg i …
