“…Mit einem Verhältnis von 6 : 1 ist das männliche Geschlecht häufiger von einer Quadrizepssehnenruptur betroffen [12]. In den letzten Jahren ist eine Vielzahl von biomechanischen Studien zu den Struktureigenschaften der Ankerfixation im Vergleich zum "Goldstandard" der transossären Fixation durchgeführt worden [10,21,28,33]. Während Hart et al [10] geringere Versagenskräfte nach Ankerfixation im Vergleich zur 3-fachen transossären Naht feststellen konnten und Lighthart et al [21] vergleichbare Struktureigenschaften ermittelten, konnten Petri et al in den durchgeführten Kadaverversuchen eine signifikant erhöhte Ausreißkraft der Titan-und Hydroxylapatitanker im Vergleich zu den transossären Nähten feststellen [28].…”

“…Poly(vinylidene fluoride) (PVDF) is a partially fluorinated polymer with critical surface tension of wetting halfway between those of poly(tetrafluoroethylene) and polyethylene . PVDF and its composites have found use in sutures, , surgical meshes, , and contact lens coatings and have been explored as membranes for topical drug release. , However, the dispersive capabilities of well-defined soluble PVDF-based polymers and their biomedical applications remain to be investigated. One of the reasons for this is relative paucity of strategies for controlled and efficient synthesis of PVDF-based complex macromolecular architectures.…”
A well-defined amphiphilic miktoarm polymer incorporating poly(vinylidene fluoride) (PVDF), polystyrene (PS), and poly(ethylene glycol) (PEG) blocks was synthesized via a combination of atom-transfer radical polymerization (ATRP), iodine transfer radical polymerization (ITP), and copper-catalyzed azide-alkyne cycloaddition (CuAAC). Morphology and self-assembly of this star polymer were examined in organic solvents and in water. The aggregates formed in water were found to possess unusual frustrated topology due to immiscibility of PS and PVDF. The polymer was evaluated for transport of small hydrophobic molecules in water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
