  • Patent number: 10996218
    Abstract: The present invention provides a method for determining the gender of a fetus by assaying the sex hormones, evaluating the overall reducing/oxidizing (redox) activity, and/or evaluating the radical scavenging capacity of the maternal urine or other body fluid. The method can be used to determine fetal gender at any time point during pregnancy. The methods of the present invention also provide for a means for pre-conception offspring gender planning by assaying the sex hormones in urine samples, evaluating the overall reducing/oxidizing (redox) activity, and/or evaluating the radical scavenging capacity of the urine or other body fluid from a non-pregnant female. In some embodiments, the methods described herein are used to sort sperm based on an overall reducing/oxidizing environment of follicular fluids, which can then be used for intrauterine insemination.

  • Patent number: 10780438
    Abstract: An interfacial technique utilizes hydrodynamic micro-vortices to perform (i) high efficiency single cell encapsulation and (ii) size-selective capturing of cells based on their sizes in a single microfluidic device. A notable feature of this technique is that it can perform high efficiency single cell encapsulation at low cell concentrations, and this technique is all passive, controlled only by the flow rates of the two phases and does not require complex structures or on-chip active devices. Single bead/cell encapsulation was demonstrated at 50% efficiency, which is at least 10 times greater than the random encapsulations at the introduced cell concentrations. Also demonstrated is the selective trapping of cells based on their sizes. This present technique expands the capabilities of droplet microfluidics for applications ranging from single cell genomics, proteomic assays to sample preparation.

  • Patent number: 10271540
    Abstract: A medical fluid for a harvested organ, tissue or part thereof, for evaluation and/or preservation. The fluid includes cocaine or a stimulating analog thereof; noradrenaline; and/or adrenaline. In addition, the fluid includes an oncotic agent, such as dextran; hormones, such as thyroxin; triiodotyronine; cortisone, insulin; and electrolytes and optionally nutrients in substantially physiological concentrations in a physiologically acceptable medium. In addition, the medical fluid further includes albumin in a concentration not exceeding 5.0%, and an oxygen carrier, such as erythrocytes. Further components may be dopamine; hydrocortisone; methylprednisolone; and a vasopressor agent, such as desmopressin. The cocaine; adrenaline; and noradrenaline are present in concentrations of each about 0.010 ?M to 0.100 ?M, for example in a ratio of 1:1:1.

  • Patent number: 10261080
    Abstract: An optical engine its use in a bench top flow cytometer, the optical engine having a set of lasers, each focused horizontally along an x-axis to a same horizontal position and vertically along a y-axis to a different vertical position along a same excitation plane of a flow cell, a set of optics that separate fluorescence of a same wavelength range into different locations in a focal plane of collection optics according to the different lasers by which the fluorescent light is excited; and a detector that selectively detects light from the different locations thereby distinguishing between fluorescence emitted within the same wavelength range as excited by the different lasers.

  • Patent number: 10247739
    Abstract: The present invention relates to a method for the immunological measurement using a hapten and an antibody binding to the hapten as a reference antibody, and a device for the immunological measurement using the reference antibody. According to the present invention, the method and the device for the immunological measurement can be used in an immunoassay by reflecting surrounding environments, for example, by reflecting a numerical value in a test zone, which is changed by external factors such as temperatures of a sample and a device, an amount and components of an injected sample, variations of the device, and the like, in a reference zone and changing the numerical value in the test zone, and can be useful in minimizing analysis errors due to a low probability of causing a non-specific reaction with a material in the sample.

  • Patent number: 10226041
    Abstract: The present invention generally relates to compositions and methods for the handling of processed sperm populations including samples that are freshly collected, those transported as fresh samples, as well as samples that are frozen and thawed, those sorted into one or more subpopulations, and those that are otherwise processed or handled that impose trauma on the sperm cell. Such trauma can reduce the motility, fertility, viability and overall integrity of the sperm and reduce the sperm's ability to fertilize an egg, grow into a health embryo and produce a healthy offspring.

  • Patent number: 10216144
    Abstract: The invention provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

  • Patent number: 10196631
    Abstract: The invention is directed to a releasable conjugate comprising a biotinylated ligand having a biotin moiety, a ligand moiety (Ligand1) and a biotin-binding molecule (bbm) bound to the biotin moiety of the biotinylated ligand. The ligand moiety of the biotinylated ligand may be separated by a spacer group consisting of polyethylene glycol. Furthermore, the invention relates to a method for cleaving the releasable conjugate by providing biotin or streptavidin and an auxiliary release agent in a sufficient concentration to displace the biotin-binding molecule (bbm) from the biotin moiety of the biotinylated ligand and a method for separation of target cells from a cell sample utilizing the conjugate.

  • Patent number: 10188631
    Abstract: The present invention relates to a novel melatonin-based formulation, particularly a topical liquid composition of melatonin (or analog thereof) suitable for use in intrauterine washing performed during medically assisted reproduction (e.g. in vitro fertilization—IVF). Melatonin is notoriously unstable, especially in solution. The compositions of the invention exhibit high stability, which allows them to be kept for prolonged periods before their eventual use in the inhibition or prevention of embryonic implantation failure.
