Abstract: The invention relates to a nucleic acid construct for expressing an active substance which is activated by an enzyme which is released from mammalian cells, which construct comprises the following components: a) at least one promoter element, b) at least one DNA sequence which encodes an active compound (protein B), c) a least one DNA sequence which encodes an amino acid sequence (part structure C) which can be cleaved specifically by an enzyme which is released from a mammalian cell, and d) at least one DNA sequence which encodes a peptide or protein (part structure D) which is bound to the active compound (protein B) by way of the cleavable amino acid sequence (part structure C) and inhibits the activity of the active compound (protein B), and also to the use of the nucleic acid construct for preparing a drug for treating diseases.

Abstract: The present invention relates to a process for determining complexes of .alpha.-1-antichymotrypsin and cathepsin G in a sample comprising adsorbing the cathepsin G portion of the complex to a solid phase coated with non-specific binding protein or gelatin, and detecting the .alpha.-1 portion of the complex with a detectably labelled anti-.alpha.-1-antichymotrypsin antibody. A diagnostic kit comprising the solid phase coated with non-specific binding protein or gelatin and the labelled anti-.alpha.-1-antichymotrypsin antibody is also provided.

Abstract: A storage facility for units, such as boats, consists of a multi-story rotatable tower having radial storage region opening to exterior of the tower, and an elevator tower fixed adjacent the exterior of the tower. The elevator tower includes a lift car having fingers movable beneath a unit to be lifted and also movable substantially radially from a retracted position to an extended position enabling units to be inverted into or removed from the storage regions and lowered to or raised from a loading/unloading station at the base of the lift tower.
