20100227314 | METHOD OF IDENTIFICATION OF GENOTYPE AND SUBTYPE OF HEPATITIS C VIRUS ON A BIOLOGICAL MICROCHIP - The invention relates to molecular biology, virology and medicine and provides a method for identifying a genotype and a subtype of Hepatitis C virus (HCV) on the basis of the analysis of an HCV genome NS5B region using a differentiating biochip. The method of the present invention is based on a two-step PCR, with a fluorescent labeled, preferably single-stranded, NS5B region fragment obtaining, followed by the hybridization of this fragment on a biochip comprising a set of specific discriminating oligonucleotides. HCV genotype and subtype identification is carried out by defining the specific sequences of the segments of the NS5B region fragment. The invention allows one to conduct an assay precisely from a clinical specimen, to determine 6 genotypes and 36 subtypes of hepatitis C virus, including the most virulent and drug resistant forms, and to reduce the cost of assay. Also, the invention deals with a biochip, a design method and a set of oligonucleotide probes usable under the implementation of the method. | 09-09-2010 |

20130215114 | METHOD AND SYSTEM FOR ROENTGENOGRAPHY-BASED MODELING - Modeling an object in 3-D space may be accomplished various embodiments disclosed herein. An exemplary method of creating a 3-D model includes receiving roentgenograms of an object and at least one reference marker. In some embodiments, the roentgenograms may each include an image of at least one object marker. The exemplary method may further include determining 3-D positions of the x-ray source using the images of the at least one reference marker. The location of the 3-D positions of the x-ray source may allow a 3-D model of the imaged object to be created. | 08-22-2013 |
