    • The present invention provides a method for determining the suitability of a sample of mammalian semen for cooling and/or cryopreservation or storage, which comprises: (a) providing said sample of semen; (b) determining the level of a hydrophobic stimulator of 11β-HSD activity in said sample; and (c) assessing, from the level of 11β-HSD stimulator determined, the suitability of the semen sample for cooling and/or cryopreservation or storage. The present invention also provides a method of obtaining a hydrophobic product that improves the tolerance of mammalian semen to cooling and/or cryopreservation or storage, a method of improving the survival rate of sperm intended for cooling and/or cryopreservation or storage and a method of performing an assisted conception/reproductive procedure comprising contacting an oocyte with sperm obtained by a method according to the present invention.

    • A method is described of inserting guide wires into a lumen, for example into the human gastrointestinal tract. A guide wire structure is employed which comprises at least two guide wires (1, 2) each having a leading end portion which terminates in a leading end, the guide wires being connected to one another by a junction (3) at or adjacent their leading ends, the guide wires have a first position in which the leading end portions are substantially parallel to one another, a second position in which theleading end portions are curved, and a third position in which at least one of the leading end portions forms a loop. The guide wire structure is steered through the gastrointestinal tract by selectively advancing or retracting a single guide wire or advancing more than one guide wire simultaneously, according to the path which is required to be followed.
    • 描述了将引导线插入管腔,例如插入人胃肠道中的方法。 引导线结构被使用,其包括至少两根引导线(1,2),每个引导线(1,2)具有终止于前端的前端部分,引导线通过接合部(3)彼此连接在其前端 导丝具有第一位置,其中前端部基本上彼此平行,第二位置,其中,顶端部弯曲;第三位置,其中至少一个前端部形成环 。 根据需要遵循的路径,引导线结构通过选择性地前进或后退单根导丝或同时推进多根导丝而转向胃肠道。
