摘要:
The invention relates to methods and reagents for promoting the differentiation of oligodendrocytes from stem cells, by co-activating the Olig genes and the Nkx2.2 genes, and the use of the differentiated oligodendrocytes thus obtained in treating diseases, such as Multiple Sclerosis (MS). The invention also relates to the use of OLPs and oligodendrocytes thus obtained for drug screening.
摘要:
An electro-hydraulic actuator includes a hydraulic pump, an electric motor operatively connected to the hydraulic pump and operable for driving the pump, an actuator moveable in response to fluid flow from the pump, and a housing for the pump, electric motor and actuator. The housing has a base member that is adapted to be modified into various configurations for forming an attachment interface for mounting of the electro-hydraulic actuator.
摘要:
The present invention comprises systems and methods for inducing auditory sensations in patients by stimulating the inferior colliculus of the mammalian midbrain. In some embodiments, the invention comprises an auditory prosthesis system comprising a microphone, a sound processor, a current stimulator, and one or more stimulating electrodes disposed in the inferior colliculus of a mammal. At least one of the stimulating electrodes may be comprised of one or more shanks, each shank comprised of one or more stimulation sites. In some embodiments, without limitation, the invention comprises methods of inducing auditory sensation in a mammal, comprising the steps of providing a microphone, a sound processor, and a current stimulator; providing one or more stimulating electrodes each comprised of two or more shanks, each shank comprised of one or more stimulation sites; disposing at least one stimulating electrode in the inferior colliculus of a mammal; and stimulating at least one isofrequency lamina of the inferior colliculus by applying an electrical signal through at least one of the stimulation sites.
摘要:
A method and system for dynamically varying intermediation functions in a communication path between a content server and a client station. An intermediation system within the communication path receives an HTTP message and detects an intermediation-variance instruction within the message. In response, the intermediation system varies a default set of intermediation logic, such as by removing, changing or adding one or more intermediation triggers and/or intermediation actions. In turn, the intermediation system applies the variant intermediation logic in response to the HTTP message and/or in response to subsequent HTTP messages.
摘要:
A method and system for providing advanced notice of cost to access web content. During transmission of web content over a communication path between a content server and a client station, an intermediation system adds into the web content, in conjunction with a hyperlink to web content, an indication of cost to access the referenced web content. The indication of cost will then be presented to a user when the web content is presented to the user, thereby giving the user an advanced notice of the cost to access the referenced content.
摘要:
Arterial and venous endothelial cells are molecularly distinct from the earliest stages of angiogenesis. This distinction is revealed by expression on arterial cells of a transmembrane ligand, called EphrinB2 whose receptor EphB4 is expressed on venous cells. Targeted disruption of the EphrinB2 gene prevents the remodeling of veins from a capillary plexus into properly branched structures. Moreover, it also disrupts the remodeling of arteries, suggesting that reciprocal interactions between pre-specified arterial and venous endothelial cells are necessary for angiogenesis. This distinction can be used to advantage in methods to alter angiogenesis, methods to assess the effect of drugs on artery cells and vein cells, and methods to identify and isolate artery cells and vein cells, for example.
