    Description / Table of Contents: Summary We report on two cases of acute knee trauma with rupture of the synovial tissue of the anterior cruciate ligament. The femoral part of the synovia had retracted and was locked between the femoral attachment of the anterior cruciate ligament and the femur condyle. Both patients showed clinical signs of an acute lesion of the medial meniscus with loss of extension and tenderness on palpation over the medial joint cavity. After complete arthroscopic resection of the interfered soft tissue, both patients had full range of motion and no signs of any knee discomfort.
    Notes: Zusammenfassung Wir berichten über 2 Fälle eines traumatischen Einrisses des Synoviaüberzugs über dem vorderen Kreuzband nach Kniegelenkverdrehtrauma. Der femorale Anteil der Synovia retrahierte sich und klemmte zwischen dem femoralen Ansatz des vorderen Kreuzbands und der Femurkondyle im Sinne eines Impingements mit schmerzbedingter Streckhemmung ein. Klinisch imponierte der Befund wie eine akute Meniskuseinklemmung. Arthroskopisch wurden eine Meniskusläsion ausgeschlossen und die eingeschlagenen Weichteile entfernt. Bei sofort postoperativ wiedererlangter schmerzfreier Beweglichkeit blieben die Patienten beschwerdefrei.

    Studies of metal–support interactions with “real” and “inverted” model systems: reactions of CO and small hydrocarbons with hydrogen on noble metals in contact with oxides (2000)

    Notes: Abstract Two types of model catalysts are compared: thin film catalysts consisting of polyhedral noble metal nanocrystals (Rh and Pt) supported by reducible and non‐reducible oxides, and their inverted pendants, submonolayers of titania and vanadia deposited under UHV conditions on the respective metal surfaces (Pd and Rh(111) and Rh (polycrystalline)). The structure and composition of the inverse catalysts were examined in situ by LEED and AES and the nanoparticles were characterized by HRTEM. The activity of thin film and inverse catalysts was studied in a series of reactions, such as the ring opening of methylcyclopentane and methylcyclobutane, the dissociation of CO and the CO methanation. Reaction conditions comprise atmospheric pressure but also molecular beam experiments. The reaction rates are related to the oxidation state of the supporting oxide, to the free metal surface area and to the number of sites at the interface between metal and support.
