摘要:
The present invention relates to enrichment and/or identification of fetal cells of a maternal blood sample using fetal cell specific ligands and/or fetal cell specific hybridization probes. Enriched or identified fetal cells may be subjected to steps of detection or diagnosis, wherefore the present invention enables non-invasive prenatal diagnostics.

The present invention relates to enrichment and/or identification of fetal cells of a maternal blood sample using fetal cell specific ligands and/or fetal cell specific hybridization probes wherein the ligand or probes are directed to an endothelial/mesenchymal marker, e.g. CD105, CD146 or CD141, in a first round of enrichment and the ligand or probes, in a second round of enrichment, are directed to an epithelial marker, e.g. a cytokeratin, such as CK7, CK8, CK18 or CK19. Enriched or identified fetal cells may be subjected to steps of detection or diagnosis, wherefore the present invention enables non-invasive 5 prenatal diagnostics.

摘要:
The invention pertains to an apparatus and method for controlled laser heating of a body. An optical integrating chamber, with an opening adjacent to the surface of the body, has a first and second aperture. A laser source, produces a beam of known power which is directed through the first aperture and the chamber opening onto the surface. A portion of the power of the laser beam is absorbed by the body, thereby heating it locally, and the remaining portion is substantially reflected back into the chamber. A photodetector samples the reflected light accumulated within the chamber through the second aperture, thereby discerning the total power of the reflected light, and enabling the computation of the absorbed power imparted as heat to the body. This computation is performed by a computer or controller, which also serves as a control feedback mechanism, by which the application of the laser is controlled based on the absorbed power imparted to the body during the heating process. Several embodiments are described, useful for a wide range of potential applications in processing and evaluation of organic and inorganic materials and structures.
