The final issue of eJIFCC 2007 is designed for publishing articles promoting the scientific achievements of young laboratory researchers participating in the so called IFCC Professional Scientific Exchange Program. The exchange of knowledge between laboratories is based on visits of young scientists to top laboratories in the field world wide. Between October 2005 and December 2006 three researchers from different European countries : Serbia, Spain and Turkey visited well known research laboratories in Austria and UK to learn new modern techniques that are or may be applied in the future in preimplantation genetic diagnosis or in diagnosis or treatment of rheumatic diseases. All three research projects were performed under the supervision of excellent scientists and professionals with original articles as the scientific output. The manuscripts have been carefully revised by the co-authors and eJ Editor and accepted for publication in December issue of eJIFCC.
Taking this occasion I would like to wish all IFCC members a Merry Christmas & Happy New Year 2008.
