  • Publication number: 20060057146
    Abstract: The present invention relates to selectively targeting tumoral vasculature in vivo using a human recombinant scFv, L19, to the angiogenesis marker ED-B domain of fibronectin. In preferred embodiments, a complete human IgG1 is employed having the variable regions of L19. In other embodiments is employed a mini-immunoglobulin generated by fusing the scFv L19 to the constant CH4 domain of a secretory IgE isoform that naturally contains a cysteine in its COOH terminal and which forms a covalently linked dimer. Different in vivo behaviour of the antibody formats is exploitable for different diagnostic and/or therapeutic purposes, depending on clinical needs and disease. The antibody molecules may be labelled as described.

  • Publication number: 20030159721
    Abstract: A food serving preparation oven is provided and includes a plurality of walls forming a heating area in which food servings to be heated are disposed and a cleaning fluid circulation assembly for performing selected cleaning of the heating area. The cleaning fluid circulation assembly is operable to circulate cleaning fluid through a loop which includes the heating area, a sump area, and a pressure side area. The cleaning fluid circulation assembly includes a pump to effect movement of cleaning fluid to an in-loop outlet opening, which opens into the heating area. A fluid distribution element disposed within the heating area at a spacing from the in-loop outlet opening directs a portion of cleaning fluid in a first directed stream into the heating area and directs another portion of cleaning fluid in a second directed stream into the heating area.

  • Publication number: 20030159687
    Abstract: A hot-air oven for the preparation of food is provided. A cooking chamber delimited by walls is provided in a housing. A blower produces a hot-air stream in the cooking chamber, and a controller controls the progress of a cooking process. A rotatable basket for food can be introduced into the cooking chamber via an opening in one of the walls. During operation the basket is subjected to a hot-air stream. A closure element is connected to the basket and serves to close off the wall opening during operation. The closure element is supported relative to the basket via a pivot bearing that is coaxial with an axis of rotation of the basket.

  • Publication number: 20020077306
    Abstract: This invention relates to chemically modified oligo-nucleotide conjugates that contain a complexing agent or complex that is bound by a connecting component to the oligonucleotides. In this case, the oligonucleotides are modified in a way that prevents or at least significantly inhibits the degradation by naturally occurring nucleases. The oligonucleotide radical can bond specifically and with high bonding affinity to target structures and can thus produce a specific therapeutic or diagnostic effect by the bound complexing agent or complex.
