Glutaraldehyde (GLUT) crosslinked porcine aortic heart valves are continued to be extensively used in heart valve replacement surgeries. GLUT does not crosslink glycosaminoglycans in the tissue and we have demonstrated that GAG loss is associated with tissue degeneration. In this study, we examined the ability of neomycin to enhance GLUT crosslinking to stabilize GAGs, as well as provide evidence...

Pharynx und Larynx stellen äußerst differenzierte Organsysteme dar und sind in viele verschiedene pathologische Prozesse mit einbezogen. Mit der Einführung von CT und MRT wurde die Beurteilung von Kopf und Hals signifikant beeinflusst. Die Darstellung klinisch schwierig beurteilbarer Regionen sowie auch Ausdehnung und Infiltrationstiefe von Raumforderungen, submuköses Wachstum, Mittellinienüberschreitung...
