Abstract: The present invention relates to a system and method of computer assisted surgery in soft tissue. The system comprises a navigated instrument (14) suitable to be inserted into a living object's soft tissue body part, wherein said navigated instrument (14) when inserted into the body part is suitable to define at least a portion of a section plane with respect to said soft tissue body part. The system further comprises a computer assisted guiding means to assist or enable guiding the instrument (14) upon insertion into the body part such that the section plane defined by said inserted instrument (14) coincides with a planned section plane.

Abstract: Polynucleotide and polypeptide sequences are described. The polypeptide sequences comprise one or more of: (a) a polypeptide having the deduced amino acid sequence translated from the polynucleotide sequence in SEQ ID NO: 1 and variants, fragments, homologues, analogues and derivatives thereof; (b) a polypeptide of SEQ ID NO: 2 and variants, fragments, homologues, analogues and derivatives thereof; or (c) a polypeptide encoded by the cDNA of NCIMB 41073 and variants, fragments, homologues, analogues and derivatives thereof.
