    Description / Table of Contents: Zusammenfassung. Eine neue endoskopische, intraluminale Valvuloplastik wird beschrieben. Es handelt sich hierbei um einen einfachen, ambulant durchführbaren Antirefluxeingriff, der bei Patienten mit frühen Stadien der gastrooesophagealen Refluxkrankheit eine Alternative zur lebenslangen medikamentösen Dauertherapie bieten könnte. Die Technik des Eingriffs, die Effektivität und erste Langzeitergebnisse im Tierversuch an Pavianen werden dargestellt.
    Notes: Summary. A new endoscopic intraluminal valvuloplasty is described. The procedure provides a simple, easy outpatient approach for antireflux surgery and is applicable to patients with early gastroesophageal reflux disease as an alternative to chronic life-long medical therapy. The feasibility, durability and efficacy of the procedure in baboons are reported.

    Studies on immobilized papain (1973)

    Notes: Papain was covalently coupled to ZrO2-coated porous glass by several different methods. These derivatives were characterized and their operational half-lives determined using casein substrate. Papain covalently coupled to the porous glass, previously converted to a carboxylic acid derivative, through amide linkage gave a 35 day operational half-life.

    Notes: A microbial protease was immobilized by covalent attachment, to porous glass. This material was characterized for pH optimum, thermal stability, and operational half-life using casein as substrate.The immobilized enzyme was used for preparation of soya hydrolysates, low in free amino acids with high solubility.

    Invertase covalently coupled to porous glass: Preparation and characterization (1972)

    Notes: The enzyme invertase has been covalently coupled to porous glass particles. The product is extremely stable over a long period of time. Kinetic values for the immobilized enzyme are similar to the native enzyme. Excellent enzymatic activity for the immobilized enzyme was exhibited over a broad pH range. The immobilized enzyme when continuously operated for one month was found to have an operational half-life of over 40 days.
