Abstract: FIELD: medicine. SUBSTANCE: method deals with treating diseases associated with different genetic disorders obtained during patient's life or caused as a result of inherited pathology. The method deals with applying either lactoferrin (LF) and/or its conjugates as a carrier of foreign genetic information for gene therapy. At injecting laboratory animals with complexes of intact LF and plasmid DNA, containing different marker genes, genetic material penetrates tissues possessing membranous LF receptors and is expressed there. Moreover, synthesis of end products of introduced genes' expression is observed in different groups of muscular fibers. Expression of marker genes in different tissues takes place, also, at injecting complexes of DNA along with LF derivatives containing either DNA-condensing polycation or DNA-condensing polycation and high-molecular polymeric carrier - dextran or phycol. Efficiency of complex-formation with LF or with its derivatives and subsequent delivery of genetic material into cells depends upon plasmid nature. Advantage of the present innovation is in the fact that the mentioned product could be used in the field of gene therapy of different human and animal diseases. EFFECT: higher efficiency. 2 cl, 3 dwg

Granted: 2003-07-20
Abstract: FIELD: radiolocation, development of promising radars or their updating. SUBSTANCE: method of radar acquisition and tracking of objects is based on use of secondary radar. Objects are in addition acquired and recognized by means of primary radar. Coordinates of object measured by secondary and primary radars are compared, corrections are computed, information obtained by secondary radar is supplemented with information obtained by primary radar alone and tracking is carried out with the help of secondary radar. When needed, operations with enlistment of primary radar are repeated. If coordinates of tracked object deviate from extrapolated value by more than threshold value or if ambiguity in tracking emerges object is followed up with the aid of primary radar with cancellation of reception of responses or prior to transmission of information to user and in those directions in which object is detected by secondary radar alone energy consumption by primary radar increase. In process of acquisition and tracking of object by means of secondary radar operational interrogation signals are determined and formed. This process of determination and formation of operational interrogation signals is based on re- radiation of flow of signals from controlled zone to ground center, on extraction of interrogation signal by ground radar and on radiation of it in analyzed direction. EFFECT: reduced energy consumption by radar for acquisition and tracking of objects, increased reliability of detection of objects. 7 cl
