20130017607 | Nanotube carrier substrate for primary tissue cultureAANM Mayr; StefanAACI LeipzigAACO DEAAGP Mayr; Stefan Leipzig DEAANM Zink; MareikeAACI LeipzigAACO DEAAGP Zink; Mareike Leipzig DEAANM Dallacasagrande; ValentinaAACI LeipzigAACO DEAAGP Dallacasagrande; Valentina Leipzig DEAANM Kas; JosefAACI LeipzigAACO DEAAGP Kas; Josef Leipzig DEAANM Reichenbach; AndreasAACI LeipzigAACO DEAAGP Reichenbach; Andreas Leipzig DE - A carrier substrate for primary tissue culture has a nanotube array. A tissue culture vessel has an outer vessel and a nanotube carrier substrate with a nanotube array, located within the outer vessel, wherein the surface roughness of the nanotube array is 1 nm to 100 nm. The nanotube array is used for in vitro culturing of primary tissue in connection with a tissue culture vessel for in vitro culturing of primary tissue and a method for in vitro culturing primary tissue, wherein a nanotube array is arranged essentially horizontal inside an outer cell culture vessel, so that openings of the nanotubes point at least in upward direction, the nanotube array is contacted with cell culture medium and an isolated primary tissue sample is placed on top-side on said nanotube array. | 01-17-2013 |
20130316390 | Method for diagnosis and/or prognosis of cancers by analysis of the mechanical properties of tumour cells - A method for diagnosis and/or prognosis of cancers, for diagnosis of the site of origin of tumour cells, for optimizing the treatment of cancer patients and for screening active substances for oncology. In the method, the mechanical properties of tumour cells and reference cells are analyzed under a mechanical load that leads to linear or nonlinear deformation of the respective loaded cell. The expansion of the cells, which results from the input of a directed mechanical stress, is used to determine the risk of tumour metastases and, if appropriate, the presence of uncontrollably proliferating and/or invasive cells, or the tissue of origin of the tumour. The risk of tumour metastases is determined on the basis of the proportion of cells in the sample that have an extension counter to the direction of stressing. The risk of the presence of uncontrollably proliferating cells is determined, in the case of nonlinear deformation of the cell, on the basis of the mean value of the expansion in the direction of stressing of cells in the sample. | 11-28-2013 |

20100243036 | Method for Fabricating a Photovolataic Element with Stabilised Efficiency - A method for fabricating a photovoltaic element with stabilised efficiency is proposed. The method comprises the following steps: preparing a boron-doped, oxygen-containing silicon substrate; forming an emitter layer on a surface of the silicon substrate; and a stabilisation treatment step. The stabilisation treatment step comprises keeping the temperature of the substrate during a treatment time within a selectable temperature range having a lower temperature limit of 50° C., preferably 90° C., more preferably 130° C. and even more preferably 160° C. and an upper temperature limit of 230° C., preferably 210° C., more preferably 190° C. and even more preferably 180° C., and generating excess minority carriers in the silicon substrate during the treatment time, for example, by illuminating the substrate or by applying an external voltage. This method can be used to fabricate a photovoltaic element, e.g. a solar cell or a solar module having an efficiency which is stable at a value higher than that of photovoltaic elements fabricated without the stabilisation treatment step. | 09-30-2010 |
