The present invention is a method for pigmenting a food or foodstuff comprising combining in a source of feed, a carotenoid ester of formula I: wherein R is methyl, C3-16-alkyl, C3-16-alkenyl, or C5-8-cycloalkyl. Further embraced by the invention are the carotenoid-enriched feeds, e.g., for poultry, fish, or crustacea, premixes for incorporation in such feeds, and beadlets containing the carotenoid ester for incorporation in such premixes. A further aspect of the present invention is carotenoid esters of formula I.

The screw unit for the adjustable and lockable spanning of distances between structural components, brackets, and for adjusting assemblies, etc., consists of a threaded pin, which has adjusting surfaces and a central bore passing through it, and a nut, which is screwed onto the threaded pin. This nut is designed as a support sleeve with an internal thread and adjusting surfaces, into which the threaded pin can be screwed until it is more or less flush. On the end facing an adjusting collar, the support sleeve is provided with an inward-projecting, ring-shaped collar with the internal thread, whereas the free end of the threaded pin is provided with a stop element to prevent the pin from being completely unscrewed.So that the unit can be adjusted not only in the height direction but also in the direction perpendicular to that, the support sleeve is attached to a sliding support element so that it can be shifted in the direction perpendicular to the longitudinal axis of the screw unit, the support element itself being held in place on a spacer.

The invention relates to tumour therapy. In one aspect, the present invention relates to conjugates of a toxin and a target-binding moiety, e.g. an antibody, which are useful in the treatment of cancer. In particular, the toxin is an amatoxin, and the target-binding moiety is preferably directed against tumour-associated antigens. In particular, the amatoxin is conjugated to the antibody by linker moieties. In particular the linker moieties are covalently bound to functional groups located in positions of the amatoxin proved as preferred positions for the attachment of linkers with respect to optimum antitumor activity. In a further aspect the invention relates to pharmaceutical compositions comprising such target-binding moiety toxin conjugates and to the use of such target-binding moiety toxin conjugates for the preparation of such pharmaceutical compositions. The target-binding moiety toxin conjugates and pharmaceutical compositions of the invention are useful for the treatment of cancer.
