  • Publication number: 20110223660
    Abstract: Disclosed is a composition for inducing the proliferation of retinal cells or the differentiation of retinal progenitor cells into retinal cells. The composition, similar to in vivo conditions for development during embryogenesis, induces stem cells to differentiate into a multitude of photoreceptor cells at high yield within a short period of time, without an additional gene transfer. In addition, the differentiated photoreceptor cells are useful in cellular therapy because they, when transplanted into degenerated or injured retinas, can be engrafted and fused within the retinas to prevent or cure retinal degeneration.

  • Publication number: 20110192980
    Abstract: The present invention relates to a system and method for compensating for anode gain non-uniformity in a Multi-anode Position Sensitive Photomultiplier Tube (PS-PMT), in which a compensation unit is disposed between the multi-anode position sensitive photomultiplier tube and a position detection circuit unit and configured to uniform a current signal inputted to the position detection circuit unit, thereby compensating for anode gain non-uniformity. In accordance with the present invention, the compensation unit for changing resistance is used. Accordingly, there is an advantage in that the gain non-uniformity of each of the anodes of the PS-PMT can be compensated for. Furthermore, the gain non-uniformity of each of the anodes of the PS-PMT is compensated for by changing resistance values of the variable resistances of the compensation unit. Accordingly, there is an advantage in that the interaction positions of gamma rays can be calculated more precisely.
