  • Publication number: 20190391216
    Abstract: The invention concerns a method for the hyperpolarisation of 13C nuclear spin in a diamond, comprising an optical pumping step, in which colour centre electron spins in the diamond are optically pumped. The method further comprises a transfer step in which the polarisation of a long-lived state of the colour centre electron spins is transferred to 13C nuclear spins in the diamond via a long-range interaction.

  • Patent number: 9005886
    Abstract: The present invention discloses a method for cryopreservation of human spermatozoa: the method comprises providing spermatozoa free from seminal liquid; mixing the spermatozoa with vitrification medium, wherein the main cryoprotectant agent is 0.1-0.3 M sucrose; placing the sample inside straws and rapidly freezing them; refrigerating the straws with no need of liquid N2; and devitrifying the sample in a medium of the present invention. The present invention furthermore discloses a portable kit that makes easy to implement the method, said kit comprising vitrification and devitrification solutions in the volumes required to develop the method and the physical support to carry out the same, i.e. the straws. The use of this kit is also disclosed for the treatment of disorders related to reproductive failures.

  • Publication number: 20120189813
    Abstract: A process for manufacturing a TEM-lamella includes mounting (51) a plate shaped substrate having a thickness in a support, manufacturing (53) a first, strip-shaped recess on a first side of the substrate under a first angle to the support by means of a particle beam, and manufacturing (55) a second strip-shaped recess on a second side of the substrate under a second angle to the support by means of a particle beam, such that the first and the second strip-shaped recess mutually form an acute or right angle, and between them form an overlap region of lesser thickness. The lamella has a thicker rim region and a thinner central region, with a first strip-shaped, recess on a first side of the lamella and a second strip-shaped recess on a second side of the lamella, wherein the first and the second strip-shaped recess mutually form an acute or right angle, and between them form an overlap region having a thickness of below 100 nm.

  • Patent number: 8126536
    Abstract: In a method for determining the pelvic inlet plane of the pelvic bone, which is defined by the following three points of the pelvic bone: point A: spina iliaca anterior superior left point B: spina iliaca anterior superior right point C: symphysis pubis, by non-invasive determination of the position of one of the two points A or B and point C, in order to also be able to carry out this determination whenever point A or point B is not accessible, it is proposed that the position of the following points of the pelvic bone be additionally determined non-invasively: point D: spina iliaca posterior superior left point E: spina iliaca posterior superior right, and that the position of the pelvic inlet plane be calculated from the position of the non-invasively determined points A or B, C, D and E.
