Publication number: 20130211061Abstract: The present invention is based on two important experimental observations: The first observation is that increased extracellular concentrations of ionized calcium are found in erosive arthritis and stimulate monocytic IL-1? release via the CaSR and GPRC6A. Simultaneous stimulation of monocytes with calcium ions and selected TLR ligands results in a 20-fold increased IL1? response compared to lipopolysaccharide (LPS) alone. During the crosstalk between GPCR and TLR signaling, phospholipase C is activated, which triggers calcium dependent potassium channels, resulting in potassium efflux, caspase-1 activation and IL-1? release. The amplification of IL1? secretion at sites of locally increased calcium ion concentrations aggravates rheumatoid arthritis. The second important observation is that both CaSR and GPRC6A, are highly expressed in the synovial membrane of patients with rheumatoid arthritis, but expression of GPRC6A, but not of CaSR, is lower in patients with osteoarthritis (s. FIG. 1).Type: ApplicationFiled: July 29, 2011Publication date: August 15, 2013Applicant: UNIVERSITÄT LEIPZIGInventors: Ulf Wagner, Manuela Rossol

Patent number: 8502815Abstract: We present a method for predictive compression of time-consistent 3D mesh sequences supporting and exploiting scalability. The applied method decomposes each frame of a mesh sequence in layers, which provides a time-consistent multi-resolution representation. Following the predictive coding paradigm, local temporal and spatial dependencies between layers and frames are exploited for layer-wise compression. Prediction is performed vertex-wise from coarse to fine layers exploiting the motion of already encoded neighboring vertices for prediction of the current vertex location. Consequently, successive layer-wise decoding allows to reconstruct frames with increasing levels of detail.Type: GrantFiled: April 18, 2008Date of Patent: August 6, 2013Assignee: Gottfried Wilhelm Leibniz Universitat HannoverInventors: Nikolce Stefanoski, Jörn Ostermann, Patrick Klie

Publication number: 20130197668Abstract: The present invention relates to a method for producing a structure modeled on a biological tissue. The invention also relates to a structure which can be produced using the method according to the invention. According to an embodiment of the invention, a precursor of a biopolymer is locally irradiated with electromagnetic radiation in a targeted manner, wherein the irradiation, in particular the selection of the areas to be irradiated, is effected according to data which describe a structural construction at least components of the extracellular matrix of the biological tissue. In this case, the electromagnetic radiation is such that two-photon or multi-photon absorption takes place in the irradiated areas of the precursor and results in the precursor being polymerized to form the biopolymer in the irradiated areas, with the result being that the precursor is at least partially solidified there.Type: ApplicationFiled: September 30, 2011Publication date: August 1, 2013Applicant: Technische Universität IlmenauInventors: Andreas Schober, Michael Gebinoga, Uta Fernekorn, Frank Weise, Jörg Hampl, Julia Katzmann, Thomas Klar
