Title: Methods for making and using reprogrammed human somatic cell nuclei and autologous and isogenic human stem cells.
Inventor: KEITH CAMPBELL
IPC: C12N15/877
Filed: 2002-11-26
Abstract: Activated human embryos produced by therapeutic cloning can give rise to human totipotent and pluripotent stem cells from which autologous cells for transplantation therapy are derived. The present invention provides methods for producing activated human embryos that can be used to generate totipotent and pluripotent stem cells from which autologous cells and tissues suitable for transplantation can be derived. In one embodiment, the invention provides methods for producing activated human embryos by parthenogenesis; in another embodiment, the invention provides methods for producing activated human embryos by somatic cell nuclear transfer whereby the genetic material of a differentiated human donor cell is reprogrammed to form a diploid human pronucleus capable of directing a cell to generate the stem to generate the stem cells from which autologous, isogenic cells for transplantation therapy are derived. The ability to create autologous human embryos represents a critical step towards generating immune-compatible stem cells that can be used to overcome the problem of immune rejection in regenerative medicine. The activated human embryos produced by the present invention also provide model systems for identifying and analyzing the molecular mechanisms of epigenetic imprinting and the genetic regulation of embryogenesis and development.

Title: Coding an audio signal.
Inventor: MATHEUS J A MANS
IPC: G10L19/00
Filed: 2003-10-31
Abstract: In the method of coding the audio signal, the values of first parameters (P1,1), which represent aspects of the audio signal at a first instant (ti), are calcul ated to obtain first calculated values (Al,i). The values of second parameters P2,i), which represent the aspects of the audio signal at a second, later, instant (t2), are calculated to obtain the second calculated values (A2,i). The number of the first parameters (Pl,i) and the number of the second parameters (P2,i) differ. A subset (SUS2,i) of the second parameters (P2,i) is associated with a particular portion (SFRAi) of a frequency range (FR) of the audio signal This frequency range (FR) of the audio signal is preferably selected to cover all the f requencies present in the audio signal. The values (A2,i) of the subset (SUS2,i) of the second parameters (P2,i) are coded based on a difference of this subset (SUS2,i) and a subset (SUS1,i) of the first calculated value(s) (Al,i) associate d with substantially this same particular portion (SFRAi) of the frequency range (FR). Thus the differentially coded values (7) of the second parameters (P2,i) are obtained by coding the difference of the values of second parameters (P2,i and first parameters (P1,i) which are associated with substantially the same frequency subrange (SFRAi). This allows to differential code the parameters (Pl,I P2,i) even if the number of the parameters changes in time.
