Abstract: A valve drive arrangement for actuating gas exchange valves of an internal combustion engine having a camshaft, on which first and second cam carriers are arranged on first and second contact regions in a non-positive and/or positively locking manner, the first cam carrier having at least one cam for actuating a gas exchange valve and the second cam carrier having at least one cam for actuating an ancillary unit, the first contact region being configured with regard to the geometric dimensions differently in relation to the second contact region in such a way that the second cam carrier can be mounted, without being impeded by the contact regions for the first cam carrier.

Abstract: A sliding cam arrangement for the variable actuation of gas exchange valves of an internal combustion engine, having a camshaft which has toothing regions with an external toothing, wherein the toothing regions mesh in each case with an internal toothing of a cam carrier, wherein the ratio of base circle radius R2 of the cam carrier to tip circle radius R1 of the toothing of the camshaft satisfies the following criteria: R2/R1<1.55.

Abstract: The present invention relates to oligonucleotides directed against a survivin gene and variants thereof and to the use of said oligonucleotides in the diagnosis, prophylaxis, reduction and follow-up of diseases associated with cell growth, differentiation and/or division, such as tumor diseases.

Abstract: The invention relates to a method for detecting increased susceptibility to tumours by specifically detecting a polymorphism in the position 354 A ? G in the exon 12 of the human murine double minute-2 (MDM2) gene. Said polymorphism represents a hereditary marker for increased risk of cancer in humans. The invention also relates to the use of said tumour susceptibility marker for developing in vitro and in vivo test systems which integrate said markers, in a specific manner, into diagnostic, prognostic and possibly therapeutic methods.
