  • Publication number: 20130197052
    Abstract: The synthesis and evaluation of gastroprotective effect of different tryptamine derivatives. Tryptamine derivatives have been synthesized by formation of amide or ester with some known anti oxidant molecules. These derivatives show excellent antioxidant property in vitro. Among all the derivatives the compound SEGA (3a), that was prepared by the combination of serotonin with gallic acid shows the greater antioxidant property than the other synthesized compounds both in vivo and in vitro. SEGA(3a) shows the gastroprotective effect against NSAIDs (indomethacin or diclofenac)-induced gastropathy in dose dependent manner and also accelerates the healing from injury. It prevents the NSAIDs-induced mitochondrial oxidative stress in vivo. This derivative prevents NSAID-induced mitochondrial oxidative stress-mediated apoptosis in vivo by preventing the activation of caspase 9 and caspase-3 and restores NSAIDs-mediated collapse of mitochondroial transmembrane potential and dehydrogenase activity.

  • Publication number: 20120278782
    Abstract: Techniques generally disclosed herein relate to computation of a guard zone of a three-dimensional object. In some examples, guard zones may be computed by identifying intersection lines that couple adjacent planes of an object, and categorizing an external angle at an intersection line between adjacent planes as concave or convex. In some embodiments, for convex angles, a cylindrical surface can be determined that is located about an outside surface of the object and centered along the intersection line between the adjacent planes. In some embodiments, for concave angles, the external angle can be bisected with a bisection plane. A guard zone may be formed by one or more of (i) providing a guard zone plane parallel to the object that is a tangent to a given cylindrical surface, (ii) providing a guard zone plane parallel to the object that intersects a given bisection plane, and/or (iii) coupling adjacent guard zone planes.

  • Publication number: 20120021453
    Abstract: Disclosed are methods and systems for identifying and sorting cells based on a near-infrared emission pattern of the cell in response to excitation at 630±nm. The NIR emission pattern can be used for monitoring and sorting of cells in a label-free manner, and thus provides a positive method for selecting cells, such as stem cells, for use in therapy.

  • Publication number: 20110158163
    Abstract: A Link Layer (e.g., TCP/IP Layer 1, OSI Layer 2) routing protocol that routes frames from a sending node to a receiving node based upon service solicitation and availability is proposed. The routing protocol may reduce control messages across the layers, and may achieve greater energy efficiency by placing non-participating nodes into a sleep mode for durations of time while an ad hoc network is being utilized by participating nodes. The proposed scheme may also reduce network setup time by enabling routing as soon as a service and corresponding request is initiated.
