Abstract: The invention relates to a method for a transmitter for a multi-channel communication system for sending real-time sensitive data D, wherein the communication system has n sub-channels, wherein n is greater than 1, wherein the sub-channels are spatially different and/or the sub-channels have different frequencies. The method comprises the steps of receiving information about the channel state of the n sub-channels, receiving information about the number of statistically independent sub-channels m, wherein m is less than or equal to n, and receiving dataD intended to be sent.

Abstract: Heparan sulphate HS/BMP2 is disclosed, together with the use of HS/BMP2 in the repair and regeneration of bone tissue.

Abstract: The invention relates to heparan sulphate GAGs obtained by affinity chromatography using the heparin-binding domain of BMP2. The GAGs were obtained from osteoblast extracellular matrix and from a commercially available heparan sulfate (Celsus HS).

Abstract: The isolation and identification of glycosaminoglycans capable of binding to proteins having a heparin-binding domain is disclosed, as well as the use of the glycosaminoglycans isolated in the growth and/or development of tissue.
