Abstract: The present invention relates to a liquid composition containing a combination of vitamins A, D, E and K or a suitable provitamin thereof in a liquid matrix, where the total amount of said vitamins and provitamins is at least 0.2% by weight of the total compositions. The invention further relates to the use of this vitamin formulation in the treatment of an existing or impending vitamin deficiency condition concerning at least one of vitamin A, D, E or K, in particular due to vitamin maldigestion. The present invention also relates to formulations for dietary purposes, cosmetic purposes or medical purposes, in particular to dosage forms for oral administration, to formulations for parenteral administration and to topical formulations. The present invention further relates to the use of the compositions for dietary purposes, including e.g. food supplementation and food for special purposes, such as a balanced diet.

Abstract: The present invention relates to the preparation and use of reversibly PEGylated nanocarriers. The reversibly PEGgylated nanocarrier system comprises an inner core comprising or consisting of a nanoparticle and/or at least one pharmaceutical compound; optionally at least one lipid bilayer on the surface of the inner core; a first ligand bound to the surface of said inner core, or if present, to the surface of the at least one lipid bilayer; a second ligand bound to the first ligand, the second ligand being covalently bound to poly(ethylene glycol) or a derivative thereof. The reversibly PEGgylated nanocarrier system is characterized in that binding of the second ligand to the first ligand is non-covalent and reversible. Pharmaceutical compositions and use of such compounds and compositions in the field of e.g. cancer therapy, gene therapy, inflammatory diseases and pain therapy are also disclosed.
