    摘要: Fusion proteins containing B7-H4 polypeptides are disclosed. The B7-H4 fusion proteins can include full-length B7-H4 polypeptides, or can contain a fragment of a full-length B7-H4 polypeptide, including some or all of the extracellular domain of the B7-H4 polypeptide. Methods for using the fusion proteins to downregulate T cell activation and for the treatment of inflammatory and autoimmune diseases and disorders are also disclosed. The B7-H4 fusion proteins are useful for treating inflammation by inhibiting or reducing differentiation, proliferation, activity, and/or cytokine production and/or secretion by ThI, ThI 7, Th22, and/or other cells that secrete, or cause other cells to secrete, inflammatory molecules, including, but not limited to, IL-1β, TNF-α, TGF-beta, IFN-γ, IL-17, IL-6, IL-23, IL-22, IL-21, and MMPs; or enhancing IL-IO secretion by Tregs, increasing the differentiation of Tregs, increasing the number of Tregs, or combinations thereof.

    摘要: A method of scatter correction for use with gamma cameras includes the steps of detecting and producing a first count value indicative of gamma radiation falling within a first energy range generally associated with a radionuclide photopeak. Gamma radiation falling within second and third energy ranges is also detected and a corresponding count produced. The second and third ranges are above and below the photopeak, respectively. The location of the second and third energy ranges is determined based on the energy resolution of the gamma camera such that a predetermined percentage of the radiation falling within the second and third ranges results from primary radiation. The second and third energy ranges may be located such that they are non-contiguous with the first energy range. Based on the count of radiation falling within the second and third ranges, the scatter radiation falling within the first energy range can be estimated, and the first count value corrected. The method is suitable for use with radionuclides having multiple closely spaced photopeaks as well as with multiple widely spaced photopeaks.

    摘要: A gamma camera system includes a rotatable gantry supporting multiple detector heads each capable of receiving radiation from a region of interest of a subject disposed in an examination region. Each of the detector heads include a collimator which substantially defines the resolution and sensitivity of the respective detector head. At least two of the detector heads include collimators providing different resolution. Preferably, one of the collimators provides a detector head with substantially high resolution and another provides a detector head with substantially high sensitivity. An operator selectively combines image data detected by each of the multiple detector heads. If desired, the operator combine the image data from the multiple detector heads in a variety of manners to obtain images of various resolution and sensitivity from a single imaging procedure. The operator may also selectively weight the contribution that the image data from each of the detector heads has in the overall image. As yet another option, the operator may choose to combine only a high energy portion of the image data so as to minimize the amount of scatter events which are included in a final image.

    摘要: A lightweight multilayer flame barrier includes alternating layers of a metal foil and an insulation layer to form a barrier layer. The metal foils may be configured on both the barrier surface and the interior surface. A barrier layer may be attached or coupled to a support layer. The lightweight multilayer flame barrier may be configured as a portable shelter that can be carried by fire service people and therefore may be lightweight and thin to enable compact storage and transport. The lightweight multilayer flame barrier may provide high convective exposure time in a thin lightweight composite.

    摘要: A transmission source serves to detect activity from a radiation source for correcting attenuation in either PET mode or SPECT mode. The transmission source includes a detector dedicated to collecting attenuation data in PET mode. A collimated radiation source and a detector are positioned with respect to a tomography device such that only a selected strip of the imaging detector of the tomograph is illuminated such that events unrelated to the attenuation are eliminated. The transmission source can either be a coincidence transmission source or a singles transmission source and includes a collimator in which is disposed a radiation source. An opening is defined by the collimator for exposing a selected portion of the imaging detectors of the tomograph device. Positioned behind the radiation source, relative to the imaging detectors, is the dedicated attenuation detector. In a dual head tomograph device, one transmission source of the present invention is disposed opposite each bank of imaging detectors. The sources and the associated collimators are positioned to the side of each head at a slight angle relative to the respective head. The sources and detectors are fixed relative to the imaging heads. In order to obtain full coverage of the field of view (FOV) in the same manner as for an emission scan, the heads and sources are rotated about the center of the camera. In SPECT mode, the point source is selected to have sufficiently high energy to shine through the patient and the collimators associated with the imaging detector.
