Patent number: 9005886Abstract: 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.Type: GrantFiled: February 16, 2011Date of Patent: April 14, 2015Assignees: Universidad de La Frontera, Universitaet UlmInventors: Raul Sanchez Gutierrez, Jennie Risopatron Gonzalez, Mabel Schulz Rubilar, Evgenia Isachenko, Vladimir Isachenko

Publication number: 20120189813Abstract: 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.Type: ApplicationFiled: July 28, 2011Publication date: July 26, 2012Applicants: CARL ZEISS NTS GMBH, UNIVERSITAET ULMInventors: Lorenz Lechner, Ute Kaiser, Johannes Biskupek
