  • Patent number: 11408031
    Abstract: Methods for non-invasive prenatal paternity testing are disclosed herein. The method uses genetic measurements made on plasma taken from a pregnant mother, along with genetic measurements of the alleged father, and genetic measurements of the mother, to determine whether or not the alleged father is the biological father of the fetus. This is accomplished by way of an informatics based method that can compare the genetic fingerprint of the fetal DNA found in maternal plasma to the genetic fingerprint of the alleged father.

  • Patent number: 11306357
    Abstract: The present disclosure provides methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a sample of DNA from the mother of the fetus and from the fetus, and from genotypic data from the mother and optionally also from the father. The ploidy state is determined by using a joint distribution model to create a set 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. In an embodiment, the mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias.

  • Publication number: 20170107576
    Abstract: The invention provides methods, systems, and computer readable medium for detecting ploidy of chromosome segments or entire chromosomes, for detecting single nucleotide variants and for detecting both ploidy of chromosome segments and single nucleotide variants. In some aspects, the invention provides methods, systems, and computer readable medium for detecting cancer or a chromosomal abnormality in a gestating fetus.

  • Publication number: 20160369333
    Abstract: The invention provides methods for simultaneously amplifying multiple nucleic acid regions of interest in one reaction volume as well as methods for selecting a library of primers for use in such amplification methods. The invention also provides library of primers with desirable characteristics, such as minimal formation of amplified primer dimers or other non-target amplicons.

  • Publication number: 20140206552
    Abstract: The present disclosure provides methods for determining the ploidy status of an embryo at a chromosome from a sample of DNA from an embryo. The ploidy state is determined by sequencing the DNA from one or more cells biopsied from the embryo, and analyzing the relative amounts of each allele at a plurality of polymorphic loci on the chromosome. In an embodiment, the ploidy state is determined by comparing the observed allele ratios to the expected allele ratios for different ploidy states. In an embodiment, the DNA is selectively amplified at a plurality of polymorphic loci by targeted sequencing. In an embodiment, the mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias.

  • Patent number: 8780443
    Abstract: Method for actuation control of a microscope, in particular of a Laser Scanning Microscope, in which, at least one first illumination light, preferably moving at least in one direction, as well as at least one second illumination light moving at least in one direction, illuminate a sample through a beam combiner, a detection of the light coming from the sample takes place, whereby, at least one part of the illumination light is generated through the splitting of the light from a common illuminating unit, characterized in that, by means of a common control unit, a controlled splitting into the first and the second illumination light takes place, in which the intensity of the first illuminating light, specified by the user or specified automatically, is assigned a higher priority (is prioritized) compared to the specified value for the second illumination light, and an adjustment for the second illumination light takes place until a maximum value is obtained, which is determined by the value specified for the f

  • Patent number: 4886532
    Abstract: Apparatus for removing and filtering dirty air from equipment such as textile spinning machines. The apparatus has a suction duct through which dirty air is drawn. An intermediate duct containing a filter unit extends from the suction duct to a blower that blows the air through a discharge duct. The intermediate duct and discharge duct are partially contiguous with a common wall that has a portion shiftable from a common wall disposition during normal operation to a common wall opening and air flow diverting position to reverse air flow through the filter unit for cleaning and to cause air to be drawn to the blower through the discahrge duct. The shiftable wall portion may be mounted for pivoting or for sliding. The intermediate duct and the discharge duct may be arranged parallel or in crossing relation and may be rectangular to semi-circular in cross-section.

  • Patent number: 4734958
    Abstract: The invention is a drafting frame of a spinning or twisting machine comprising a plurality of roll pairs or roll triads comprising upper and lower rolls, the upper rolls being guided at their ends by bearings in at least one supporting arm rotatable about a pivot shaft with the spacing of the upper rolls from each other being changeable. Each of the bearings is a guide means, advantageously an open ended slot, aligned with an axis of a lower roll. Every supporting arm has at least two guide means spaced from each other for at least one of the upper rolls.
