  • Publication number: 20240336973
    Abstract: The invention provides methods for preparing a preparation of amplified DNA derived from a biological sample of a pregnant woman useful for identifying neoplasm in a pregnant woman, comprising: (a) isolating cell-free DNA from a biological sample of a pregnant woman comprising a mixture of fetal cell-free DNA and maternal cell-free DNA; (b) preparing a preparation of amplified DNA by performing targeted multiplex amplification on the isolated cell-free DNA to amplify at least 100 polymorphic loci; (c) analyzing the preparation of amplified DNA by sequencing the amplified DNA to obtain sequence reads of the at least 100 polymorphic loci and using the sequence reads to identify copy number variations (CNVs) in fetal and maternal chromosomes or chromosomal segments of interest, and identifying neoplasm in the pregnant woman by the presence of two or more of CNVs in the maternal chromosomes or chromosomal segments of interest.

  • Patent number: 11659938
    Abstract: The present disclosure provides for a coated flexible open-cell polyurethane foam structure. The coated flexible open-cell polyurethane foam structure includes a flexible open-cell polyurethane foam having a first major surface and a second major surface opposite the first major surface. The coated flexible open-cell polyurethane foam structure further includes a flexible heat conductive material covering 30 to 90 percent (cov., expressed in %) of a surface area of the first major surface of the flexible open-cell polyurethane foam in a predefined shape to provide one or more gaps exposing the flexible open-cell polyurethane foam between defined edges of the flexible heat conductive material, where each gap of the one or more gaps has a gap width according to Formula I: gap width (mm)??0.196×cov. (%)+20.6 (Formula I) where a total surface area of the one or more gaps provides 70 to 10 percent of the surface area of the first major surface of the flexible open-cell polyurethane foam.

  • Patent number: 11453531
    Abstract: The present disclosure is directed to a dosing cap (10). In an embodiment, the dosing cap (10) includes (A) a collar member (12). The collar member (12) has an annular skirt (18) depending from a base (16)(B). An inner surface of the skirt has a securing member for securing the collar member to a neck (21) of a container (20). The base (B) has (i) a top surface (30) and a bottom surface (32), (ii) a valve seat (34) is present on the top surface of the base. The valve seat has a center channel (36), and a radial channel (38), the channels extend through the base. The dosing cap includes (C) a plug member (40). The plug member is composed of a polymeric material. The plug member has the following components in inter-connected relationship: a head (42), a body (44), a leg (46), an ankle (48), and a flexible foot (50). The leg extends through the center channel, such that the head opposes the valve seat on the top surface of the base and the foot opposes the bottom surface of the base.

  • Publication number: 20220040650
    Abstract: A mixing device for a magnetic bead reagent includes a magnetic member, a container storage mechanism, and a drive mechanism. The container storage mechanism includes a mounting part for mounting a magnetic bead liquid container storing a magnetic bead reagent, and the mounting part corresponds to the magnetic member, enabling the container on the mounting part to be located within the magnetic field. The drive mechanism has a drive structure capable of driving at least one of the magnetic member, the mounting part, and the container to move, and thus generating a relative movement between the container and the magnetic field. The direction of the magnetic force acting on the magnetic beads is changed by the relative movement between the magnetic bead reagent and the magnetic field, such that the magnetic beads flow along different directions under the magnetic force, thereby increasing mixing efficiency of magnetic bead reagent.
