Publication number: 20220183617Abstract: A method of measuring a biomechanical parameter of soft biological tissue is described. The method includes a pre-measurement process wherein an impulse applying device applies a pre-pressure to a surface of the tissue via an end portion contacting the tissue surface. While maintaining the pre-pressure, the device generates at least two impulses separated by a time interval, each impulse causing the end portion to impart to the tissue an action with certain parameters, each action inducing a response of the tissue. A value of a biomechanical parameter of the tissue is determined from each response induced. A determination is made as to whether the determined values of the biomechanical parameter are sufficiently similar to each other to indicate that the pre-pressure, the parameters of the end portion actions and the time interval are acceptable for use in a measurement process to be conducted on the surface of the tissue.Type: ApplicationFiled: March 23, 2020Publication date: June 16, 2022Applicants: VANDERBILT UNIVERSITY, UNIVERSITY OF TARTUInventors: Arved Vain, Eric Tkaczyk, Mihkel Pöldemaa

Patent number: 9176064Abstract: This invention relates to fluorescent probes for screening and characterization of compounds binding to protein kinase CK2, measurement of concentration of the catalytically active form of CK2 and imaging of CK2 activity in cells and tissues. The CK2-selective probe of the present invention interacts with binding sites of both substrates of the catalytic subunit of CK2 and therefore can be used for characterization of all inhibitors binding to the active site of CK2 in the binding/displacement assay. The high affinity of the probe affords the detection of the enzyme at low concentration and characterization of inhibitors in a wide affinity range.

Patent number: 8753536Abstract: Method of preparation of surface coating of variable transmittance and an electro-optical layered appliance including the same comprises dispersing of liquid crystal microdroplets in hydrolyzable and polymerizable precursors and applying obtained mixture on a surface by spraying. Applying the material to the surface by spraying is intrinsically related to the synthesis processes because the properties of the surrounding environment (i.e. content of water and acidity, UV radiation) and the chemical reactions that take place during spraying have considerable influence on the properties (i.e. driving voltage, thickness of obtained layer). Obtained layered appliance comprises of a matrix material with dispersed microdroplets of liquid crystal obtained by the described method, electrically conductive transparent electrodes with contacts, a dielectric material, substrate and covering layers.Type: GrantFiled: March 25, 2010Date of Patent: June 17, 2014Assignees: University of Tartu, Estonian Nanotechnology Competence CentreInventors: Martin Timusk, Martin Järvekülg, Kristjan Saal, Rünno Lõhmus, Ilmar Kink, Ants Lõhmus

Patent number: 8597610Abstract: In the current invention a method for the preparation of an oxide material was described that involves bringing the sol onto the substrate, the gelation of the solution and thermal treatment of the gel. Alkoxides are used as precursor materials for the sol preparation and substrate free structures are employed for the manufacturing of the oxide material. A gel film with thickness ranging from 5 nm to 1 ?m is created onto the sol layer. The gelled film is separated into pieces by self organizing and the gelled part is disconnected from the substrate. Substrate free tubular structures with diameters ranging from 0.01-100 ?m are formed of the gel film which are then heated at temperature range of 200-1600 C during a period of 5 minutes to 10 hours. The manufactured oxide materials are employed as catalysts, gas sensors, stationary phases of chromatographic columns, composite materials, thermal isolation materials and micro- or nano electronic mechanical systems (MEMS or NEMS) components.Type: GrantFiled: June 9, 2008Date of Patent: December 3, 2013Assignees: Estonian Nanotechnology Competence Centre, University of TartuInventors: Martin Järvekülg, Valter Reedo, Uno Mäeorg, Ilmar Kink, Ants Löhmus
