摘要:
The present invention provides particular anti-inflammatory factors, compositions containing them, methods of making, identifying, and/or characterizing them, and methods of using them. In some embodiments, provided factors are expressed by human bone marrow stromal cells (MSC). In some embodiments, provided factors are characterized by an ability, when contacted with mammalian leukocytes in culture, to alter production of at least one inflammatory or anti-inflammatory agent by the mammalian leukocytes. In some embodiments, provided factors include GALNT1 polypeptides, LGALS3BP polypeptides, MFAP5 polypeptides, PENK polypeptides and/or HAPLN1 polypeptides. In some embodiments, provided factors are useful in the inhibition of inflammatory agents, in the promotion of anti-inflammatory agents, and/or for the treatment of subjects suffering from or susceptible to a disease, disorder or condition characterized by inflammation.

摘要:
Common authentication and authorization (AA) between networks having disparate access technologies may enable a seamless user transition between the networks. A set of AA credentials from a user attempting to gain access to one of the networks may be received, and a subscriber database of another of the networks may be used to verify the set of AA credentials. A communication protocol common to the networks may be used. Additionally, the user may employ a single set of authentication and authorization (AA) credentials, usable over multiple communication protocol layers. Further, a user may perform a single authentication and authorization (AA) operation when roaming across two or more networks by gathering user's key material during an AA challenge and reply session at a data link layer. The gathered material may be used for an AA challenge at an upper network layer or another network as the user transitions between networks.
摘要:
Methods are provided for promoting formation of collateral blood supply at an ischemic site in tissue by culturing early attaching cells derived from growth of bone marrow aspirate in vitro, collecting early attaching cells produced by the bone marrow culture and injecting conditioned medium produced by culture of the early attaching cells into an ischemic site in heart or limb. The preferred early attaching cells for use in the invention methods are marrow-derived stromal cells. Any donor's bone marrow can be used in preparation of the conditioned medium. Optionally, the early attaching cells can be transfected with an angiogenesis promoting transgene encoding hypoxia inducing factor 1 alpha, a fibroblast growth factor and/or a nitric oxide synthase. Conditioned media containing angiogenic cytokines produced such cells are also provided for injection into tissue, such as heart or peripheral limb muscle, requiring formation of collateral blood supply.

Disclosed and claimed are compositions and methods for therapy and/or prevention of restenosis and/or atherosclerosis. The compositions can include an agent for inhibiting VEGF and an agent for including vessel maturation; for instance, the soluble VEGF receptor and ang-1. Embodiments can include kits.
摘要:
A method of drilling and installing a pile in ground comprising the steps of providing a pile, providing a drill bit at an end of the pile rotatable relative to the pile; engaging the ground with the drill bit, and rotating the drill bit relative to the ground and the pile generating a hole into which the pile is received.
摘要:
A propulsion system comprising independent rotor sub-systems producing a thrust force of a desired magnitude in any desired radial direction from the centre of the propulsion system, driven from a single driveshaft that may be fixed in its position in the vehicle. When the propulsion system is fitted, for example, to a single-main-rotor helicopter in place of the convention anti-torque tail rotor, the helicopter is thereby equipped with a propulsion system that can produce yaw, pitch, the anti-torque lateral thrust for stability in hover, aft thrust or drag as well as the direct forward thrust that will enable the helicopter to fly at higher speeds. The propulsion system may also be applied in other aeronautical systems as well as to marine and industrial systems to impart energy into a fluid and thereby induce movement in that fluid.
