    • An improved powder particle supply and transport apparatus and method include a hopper filled with powder particles, an ejection chamber spaced from the hopper and a movable conveying member with a plurality of cavities formed therein. During operation, the conveying member moves the cavities between the hopper and the chamber, and the cavities are filled with powder particles at the hopper and emptied of powder particles at the chamber. An ejector nozzle sprays pressurized air into the chamber toward an aligned outlet, thereby to: 1) create negative pressure in the chamber to draw powder particles from the cavities as the cavities are moved therethrough; and 2) transport powder particles through the outlet to a spray gun. Additional structure may be used to assure complete powder filling of the cavities at the hopper and/or complete powder emptying of the cavities in the chamber. The invention achieves supply and transport of uniform and stable quantities of powder particles to a spray gun, even over very small units of time, regardless of powder particle size and/or cohesive properties.
    • 改进的粉末颗粒供应和输送装置和方法包括填充有粉末颗粒的料斗,与料斗间隔开的喷射室和在其中形成有多个空腔的可移动输送构件。 在操作期间,输送构件使料斗和腔室之间的空腔移动,并且空腔在料斗处填充有粉末颗粒,并在室处排出粉末颗粒。 喷射器喷嘴将加压空气喷射到朝向对准的出口的腔室中,从而:1)当腔体通过其移动时,在腔室中产生负压以从空腔抽吸粉末颗粒; 和2)通过出口将粉末颗粒输送到喷枪。 可以使用附加结构来确保在料斗处的空腔的完全粉末填充和/或完全粉末排空腔室中的空腔。 本发明即使在非常小的单位时间内也能够均匀稳定地将粉末颗粒供给和输送到喷枪,而与粉末粒度和/或内聚性无关。

    • Provided is a pharmaceutical composition for treating cancer and asthma.The object can be solved by a pharmaceutical composition comprising a siRNA molecule that directs cleavage of mRNA of mucin subtype 5 AC via RNA interference, or an antibody against mucin subtype 5AC as an active ingredient. According to the pharmaceutical composition of the present invention, diseases involving an overexpression of mucin subtype 5 AC can be treated efficiently. In particular, the pharmaceutical composition comprising a siRNA molecule of the present invention is effectively used in the treatment of a cancer, particularly pancreatic cancer. In addition, the siRNA or the antibody of the present invention can inhibit the expression or function of MUC5AC, thereby preventing or treating the symptoms of asthma effectively.
    • 提供了用于治疗癌症和哮喘的药物组合物。 该目的可以通过药物组合物来解决,所述药物组合物包含通过RNA干扰引导粘蛋白亚型5AC的mRNA的切割的siRNA分子,或抗5mM的粘蛋白抗体作为活性成分。 根据本发明的药物组合物,可以有效地治疗涉及5型AC粘蛋白过表达的疾病。 特别地,包含本发明的siRNA分子的药物组合物有效地用于治疗癌症,特别是胰腺癌。 此外,本发明的siRNA或抗体可以抑制MUC5AC的表达或功能,从而有效地预防或治疗哮喘的症状。
