    • This invention discloses methods for identifying Francisella tularensis vaccine candidates. It enables identification of novel vaccine candidates and quality assurance for vaccine batches, assessment of protection in vaccinates and identification of the infecting agent in vaccinates. Mice were first vaccinated with Brucella abortus O-polysaccharide (OPS) vaccine. These animals were then given 10 LD50s of F. tularensis live vaccine strain (LVS). Sixty percent (60%) of the vaccinated mice survived the multiple lethal doses. Sera were collected from these surviving mice and the antibodies were used to probe supernatant and cell lysates of live F. tularensis LVS cultures. Several F. tularensis components were identified only by the noted “survivor” antisera. Of these identified proteins, enzyme digestions and chemical oxidation suggest post-translational modifications of some proteins e.g. a 52 kDa glycoprotein, a 45 kDa lipoprotein and a 19 kDa nucleoprotein. The 52 kDa component caused nitrous oxide induction in tissue cultures at low concentrations, cell death at high concentrations. Vaccination with this gave partial protection while addition of other components acted synergistically to give enhanced protection from 250 LD50s of F. tularensis LVS.
    • 本发明公开了用于鉴定土拉弗朗西丝杆菌疫苗候选物的方法。 它能够识别新型疫苗候选物和疫苗批次的质量保证,疫苗接种中的保护评估和疫苗接种中感染剂的鉴定。 首先用Brucella abortus O-polysaccharide(OPS)疫苗接种小鼠。 然后给予这些动物10只LD50的土拉曼杆菌活疫苗株(LVS)。 接种疫苗的小鼠中有60%(60%)存活多次致死剂量。 从这些存活的小鼠中收集血清,并使用抗体来探测活的土拉氏木霉LVS培养物的上清液和细胞裂解物。 几种罗非鱼片组分仅由所述的“幸存者”抗血清鉴定。 在这些鉴定的蛋白质中,酶消化和化学氧化表明某些蛋白质的翻译后修饰,例如 一个52 kDa的糖蛋白,一个45 kDa的脂蛋白和一个19 kDa的核蛋白。 52 kDa组分在低浓度组织培养物中引起氧化亚氮诱导,高浓度细胞死亡。 用这种疫苗接种给予部分保护,而加入其他成分则协同作用,从而提高了对土拉氏杆菌LVS的250 LD50的保护。

    • The present invention relates to a signal processing method and system for correcting organ motion artifacts for cardiac and brain imaging. A plurality of sets of MRI measurement data indicative of at least an image of an object is received. Each set corresponds to one row kx of a k-space matrix of at least a k-space matrix. For each set a k-space matrix of the at least a k-space matrix is determined for allocation thereto based on motion information of the object occurring during acquisition of the plurality of sets of the MRI measurement data. In a following step a location within the allocated k-space matrix corresponding to a row of the k-space matrix allocated thereto is determined for each set. At least a k-space matrix is then generated by re-arranging the plurality of sets. Each of the at least a k-space matrix comprises the sets of the plurality of sets of the MRI measurement data allocated thereto. Inverse Fourier transforming of the plurality of k-space matrices provides at least a reconstructed image. Through careful selection of the phases of the cardiac and respiratory cycles and corresponding ranges MRI data acquisition periods are of the order of seconds or a few minutes. Furthermore, integration of motion artifact free MRI images of different phases of organ motion using the coherent k-space synthesis according to the invention allows provision of an animation showing different phases of a cardiac or lung cycle. In an embodiment for correcting motion artifacts for brain imaging a motion vector describing translational and rotational motion of a patient's head is tracked during the MRI data acquisition process. The motion artifacts are then corrected based on coherent k-space synthesis using the motion vector data.
    • 本发明涉及用于校正心脏和脑成像的器官运动假象的信号处理方法和系统。 接收指示对象的至少一个图像的多组MRI测量数据。 每个集合对应于至少一个k空间矩阵的k空间矩阵的一行k×××。 对于每个集合,基于在获取多组MRI测量数据的采集期间发生的对象的运动信息,确定至少k空间矩阵的k空间矩阵用于分配。 在随后的步骤中,针对每个集合确定与分配给其的k空间矩阵的行相对应的所分配的k空间矩阵内的位置。 然后,通过重新排列多个集合来生成至少一个k空间矩阵。 所述至少k空间矩阵中的每一个包括分配给其的所述多个MRI测量数据的集合。 多个k空间矩阵的逆傅立叶变换提供至少一个重构图像。 通过仔细选择心脏和呼吸周期的相位和相应范围,MRI数据采集周期大约为数秒或数分钟。 此外,使用根据本发明的相干k空间合成的器官运动的不同阶段的运动伪像自由MRI图像的集成允许提供显示心脏或肺循环的不同阶段的动画。 在用于校正脑成像的运动伪像的实施例中,描述了在MRI数据采集过程期间描述患者头部的平移和旋转运动的运动矢量。 然后基于使用运动矢量数据的相干k空间合成校正运动假象。

    • The present specification describes a process by which a blood substitute (hereinafter referred to as "HemoSafe") is derived from uniformly stabilized monomers and polymers of deoxyhemoglobin in its tight (T) conformation, with oxygen affinity similar to that of human blood. Two classes of HemoSafe are derived respectively from anima-hemoglobin and human-hemoglobin. HemoSafe (animal) differs from HemoSafe (human) in that it is free of polymers in order to reduce potential immunogenicity if used in man. Both types of HemoSafe may be derived in the following manner. The stabilized deoxyhemoglobins are converted to their carbonmonoxy derivatives (CO-HemoSafe) which are then stable under pasteurization conditions to render them viral disease transmission-free. CO-HemoSafes are stable for 2 months at 56.degree. C. in either the solution or the freeze-dried state. For transfusion CO-HemoSafes are easily oxygenated under sterile conditions by photoconversion yielding oxy-HemoSafe. In addition a transfusable met-hemoglobin derivative for treatment of cyanide poisoning, is derived by converting oxy-HemoSafe to met-HemoSafe.
    • 本说明书描述了血液替代物(以下称为“HemoSafe”)来源于其紧密(T)构象中的均匀稳定的单体和脱氧血红蛋白的聚合物,氧亲和力与人血液相似。 HemoSafe两类分别来源于动脉血红蛋白和人血红蛋白。 HemoSafe(动物)与HemoSafe(人类)不同之处在于,如果在人体中使用,则它不含聚合物以降低潜在的免疫原性。 两种类型的HemoSafe可以以下列方式得出。 稳定的脱氧血红蛋白被转化为它们的碳单氧基衍生物(CO-HemoSafe),然后在巴氏灭菌条件下稳定,使其无病毒传播。 CO溶液在溶液或冷冻干燥状态下在56℃下稳定2个月。 对于输血,CO-HemoSafes在无菌条件下通过光转换容易地氧合,产生oxy-HemoSafe。 另外,用于治疗氰化物中毒的可输送的met-hemoglobin衍生物是通过将oxy-HemoSafe转化成met-HemoSafe得到的。

    • A filter canister assembly utilizes a sealant deflector to seal a particulate filter to the canister wall, even after the canister is sealed. The canister housing has a wall and an aperture with a particulate filter disposed therein. The particulate filter has an edge adjacent the wall, and is designed for removing particles of contaminants from a fluid, such as air, passed through the canister. A sealant deflector includes a plurality of vanes standing proud of a support substrate, and is situated between the aperture and the particulate filter and forms a permanent part of the canister assembly. The sealant deflector deflects a sealant in liquid state toward the wall to form a seal between the edge and the wall when the sealant is deposited on the sealant deflector while spinning. This deposits a sealant ring sealing the wall to the edge. The sealant deflector is self-centered under the aperture, by a bow-tie shaped structure of four arms extending outward radially from the sealant deflector connected in pairs by curved braces.
