摘要:
Blood plasma of pregnant women contains fetal and (generally>90%) maternal circulatory extracellular DNA. Most of said fetal DNA contains .Itoreq.500 base pairs, said maternal DNA having a greater size. Separation of circulatory extracellular DNA of .Itoreq.500 base pairs results in separation of fetal from maternal DNA. A fraction of a blood plasma or serum sample of a pregnant woman containing, due to size separation (e.g. by chromatography, density gradient centrifugation or nanotechnological methods), extracellular DNA substantially comprising .Itoreq.500 base pairs is useful for non-invasive detection of fetal genetic traits (including the fetal RhD gene in pregnancies at risk for HDN; fetal Y chromosome-specific sequences in pregnancies at risk for X chromosome-linked disorders; chromosomal aberrations; hereditary Mendelian genetic disorders and corresponding genetic markers; and traits decisive for paternity determination) by e.g. PCR, ligand chain reaction or probe hybridization techniques, or nucleic acid arrays.

Imidazopyridine, imidazoquinoline, and imidazonaphthyridine compounds having an amide substituent at the 1-position, pharmaceutical compositions containing the compounds, intermediates, and methods of making and methods of use of these compounds as immunomodulators, for modulating cytokine biosynthesis in animals and in the treatment of diseases including viral and neoplastic diseases are disclosed.
摘要:
A method using fluorescence microscopy for image evaluation using a laser scanning microscope in which an at least partially spectrally resolved detection of the fluorescence spectrum occurs. Reference spectra are used for spectral demixing. Temporally and/or spectrally variable dyes and/or dye combinations are employed for recording of the reference spectra. Finally, the recorded reference spectra are inspected for image evaluation.

摘要:
Imidazo-quinoline, -pyridine, and -naphthyridine ring systems (particularly quinolines, tetrahydroquinolines, pyridines, 1,5-naphthyridines, 1,5-tetrahydronaphthyridines) substituted at the 1-position with a cyclic substituent, pharmaceutical compositions containing the compounds, and methods of use of these compounds as immunomodulators, for inducing cytokine biosynthesis in animals and in the treatment of diseases including viral and neoplastic diseases are disclosed.
摘要:
A grate covering for an incineration grate of an incineration furnace having a combustion chamber, includes a plurality of metal grate bars, each having a surface facing the combustion chamber that includes a layer made of a temperature-resistant, corrosion-resistant and abrasion-resistant non-metallic material, wherein a thickness of the layer is minimally sufficient to bear pressure and thrust loading. The thickness of the layer is about 10 mm to 15 mm. For a forward feed grate, the layer on each metal grate bar is present only in a zone of contact with an adjacent metal grate bar, and for a roller grate, and wherein the layer is present on the entire surface facing the combustion chamber.
摘要:
The present disclosure provides methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a mixed sample of DNA comprising DNA from both the mother of the fetus and from the fetus, and optionally from genotypic data from the mother and father. The ploidy state is determined by using a joint distribution model to create a plurality of expected allele distributions for different possible fetal ploidy states given the parental genotypic data, and comparing the expected allelic distributions to the pattern of measured allelic distributions measured in the mixed sample, and choosing the ploidy state whose expected allelic distribution pattern most closely matches the observed allelic distribution pattern. The mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias, for example using massively multiplexed targeted PCR.
