20090261387CMOS integrated process for fabricating monocrystalline silicon micromechanical elements by porous silicon micromachining - The invention relates to a process for fabricating a monocrystalline Si-micromechanical element integrated with a CMOS circuit element within the CMOS technology, wherein a domain of second conducting property is formed within a substrate of first conducting property, here the second conducting property is reverse with respect to the first conducting property, then simultaneously with or immediately after this a domain of monocrystalline Si is formed within the substrate for fabricating a micromechanical element. After this, a CMOS circuit element is fabricated within the substrate through the known steps of CMOS technology and then the circuit element, as well as a portion of said domain for fabricating the micromechanical element that will carry the micromechanical element after its fabrication are covered with a protecting layer. Then by starting a front-side isotropic porous Si-etching from the exposed surface of said domain for fabricating the micromechanical element and by continuing the etching until said portion that will carry the micromechanical element after its fabrication becomes at least in its full extent underetched, a porous Si sacrificial layer is created which at least partially encloses said portion that will carry the micromechanical element after its fabrication. As a next step, the exposed surface of said porous Si sacrificial layer is passivated by applying a metallic thin film thereon and metallic contact pieces of the circuit element through the known steps of CMOS technology are formed. Finally, the metallic thin film that covers the exposed surface of the porous Si sacrificial layer is removed and the micromechanical element is formed by chemically dissolving said porous Si sacrificial layer.10-22-2009

20090155228COMPOUNDS, KITS AND METHODS FOR CONFERRING CYTOPROTECTION - hABCG2, a member of the ATP-Binding Cassette transporters has been identified as a protective pump against endogenous and exogenous toxic agents. ABCG2 was shown to be expressed at high levels in stem cells, and variably regulated during cell differentiation. It is demonstrated herein that functional ABCG2 is expressed in human monocyte-derived dendritic cells by the activation of a nuclear hormone receptor, PPARg. The present results uncovered a mechanism by which up-regulation of functional ABCG2 expression can be achieved via exogenous or endogenous activation of the lipid activated transcription factor, PPARg. Thus the invention relates to combined treatments by PPARg agonists and cytotoxic drugs transportable by ABCG2, various treatments in the field of neoplastic diseases as well as cell therapy, including autologous cell therapy, as well as kits and composition therefor. Method for protecting cells against cytotoxic drugs are also provided.06-18-2009

20100047792LABEL-FREE OPTICAL DETECTION METHOD - The present provides optical sensor based sensitive, label-free binding assay methods and kits for isothermal real-time detection of the binding of specific analytes (such as nucleic acids, proteins and low molecular weight antigenic or receptor binding ligands) present in low amount in different biological samples. In the binding assays of the invention, the analyte is captured at the specifically pretreated solid surface of optical biosensors in specific recognition reactions (such as hybridization, specific protein-protein interactions and receptor-ligand interactions). The specificity of the methods of the invention is further enhanced by a second specific recognition step using a padlock probe comprising an indicator sequence designed to keep the products of a subsequently performed isothermal nucleic acid amplification method (e.g. rolling circle amplification: RCA) anchored on the sensor surface, enhancing thereby the sensitivity of the detection of the specific binding of the analyte occurred on the sensor surface.02-25-2010
