Patent number: 8609413Abstract: A method of preparing neural precursor cells by exposing pluripotent stem cells or neural stem cells to a differentiation agent. The agent is a pyridine analog, which in preferred embodiments is a phenylethynyl-substituted or phenylazo-substituted pyridine. In other embodiments, a method of enhancing neural precursor cell survival is provided in which the survival is enhanced by exposure to the pyridine analog. In further embodiments, a method of preparing neuronal cells is provided in which pluripotent or neural stem cells exposed to the pyridine analog are then incubated without the pyridine analog, resulting in differentiation into neurons, astrocytes and oligodendrocytes.

Patent number: 8179923Abstract: A system and a method provide a real-time-critical communication and a non-real-time-critical communication in a switched data network consisting of users and switching units, for example a distributed automation system, by a cyclic operation. In a transmission cycle, there exists for all users and switching units of the switched data network in each case at least one section for transmitting real-time-critical data and at least one section for transmitting non-real-time-critical data, as a result of which the real-time-critical communication is separated from the non-real-time-critical communication. Since all users and switching units are always synchronized to a common time base, the respective sections for transmitting data in each case take place at the same time for all users and switching units, i.e. the real-time-critical communication takes place independently in time from the non-real-time-critical communication.Type: GrantFiled: May 27, 2010Date of Patent: May 15, 2012Assignee: Siemens AktiengesellschaftInventor: Karl-Heinz Krause
