  • Patent number: 8361796
    Abstract: The present invention is directed to a method for the in vitro preparation of cardiovascular progenitors cells from mammalian embryonic stem cells (ES cells) or mammalian embryonic-like state cells, preferably from primate, wherein said method comprises the use of the CD15 (SSEAI) marker as a positive cardiovascular progenitors differentiation marker. The present invention also claimed the use of a receptor tyrosine kinase inhibitor, particularly the SU5402 or SU11248 in association with the BMP2 for improving the efficiency of the desired differentiation. The present invention is also directed to the use of platelet lysate as foetal animal serum substitute in a culture medium intended to the proliferation or propagation of primate ES cells maintaining their pluripotency feature. Derived compositions or kits in relation with the claimed methods or product obtainable by the claimed methods form also part of the present invention.

  • Patent number: 7877066
    Abstract: An embodiment of the present invention provides an RF log-amp detector, comprising a pre-amplifer at the input of the RF log-amp detector, a plurality of limiters with variable gain connected to the pre-amplifier, wherein the gain of the preamplifier is set to its minimum and the dynamic range is expanded by modifying the amplification gain of the plurality of limiters, thereby increasing the dynamic range and reducing accuracy, after which a coarse measurement of a power level is taken and wherein the RF log-amp detector then defines which pre-amplification level is required based on the course measurement to bring the signal at the output of the preamp within an optimum dynamic range of the log-amp and wherein the pre-amplification gain is then set while the gain of the plurality of limiters are set to their minimum value with the RF log-amp then performing a second measurement with higher accuracy and calculating the final measurement from fine measurements and the pre-amplification gain.
