summaryOrganic-free specimens of 5 metals were prepared and characterized by parameters indicating their relative surface charge, surface texture, and surface energy prior to evaluation of their degree of thromboresistance. For the materials studied, there was no predictive correlation between the pre-implantation electrical rest potentials and ultimate thromboresistance when standard prosthetic rings were placed in the canine inferior vena cava. Surface textural inhomogeneities greater than a micrometer or s…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
