  • Patent number: 11781105
    Abstract: A system for quickly determining antibiotic sensitivity of a microorganism comprising a triangular-shaped plate and cover for culturing, recovering, and re-suspending recovered microbial colonies and a second triangular-shaped plate comprising a non-liquid medium cut with concentric trenches over which the re-suspended microbial colonies are distributed by centrifugation and contacted with antimicrobial strips or disks.
    Type: Grant
    Filed: June 5, 2020
    Date of Patent: October 10, 2023

  • Patent number: 11534092
    Abstract: A blood collection tube for physically separating the plasma and red blood cell fractions of a centrifuged sample is described. The blood collection tube has an elastomeric sleeve with rigid tube segments at both ends. Following blood collection and centrifugation, the elastomeric sleeve may be twisted to constrict its inner diameter and physically separate the two fractions. The blood collection tube may be secured in this position with a pin and a clamp, and further with an adhesive tape with pH paper. This enables blood samples to be transferred over long distances to a central lab facility without spoiling.

  • Publication number: 20210246470
    Abstract: A ribonucleoprotein (RNP) delivery system comprising (a) a cationic lipid; (b) a phospholipid; (c) a peptide of the structure A-B-C in which A is a polycationic nucleic acid-binding component, B is a spacer element comprising two or more amino acid residues, and C is a cell surface receptor binding component; and (d) a ribonucleoprotein (RNP) complex comprising a CRISPR-associated protein and guide RNA, pharmaceutical compositions comprising such a ribonucleoprotein (RNP) delivery system, and methods for the treatment or prophylaxis of a condition caused in a human or in a non-human animal by a defect and/or a deficiency in a gene, or for RNA therapy, or for the treatment of a cancer, which comprises administering the RNP delivery system or pharmaceutical composition to the human or to the non-human animal.

  • Patent number: 9253785
    Abstract: Embodiments enable cooperative transmissions from a group of cells (can include the serving cell and one or more neighboring cells) to a user equipment (UE). The cooperative transmissions emulate Hybrid Automatic Repeat Request (HARQ) transmissions to the UE. Specifically, when the UE is experiencing high interference, the UE's serving cell can create a transmit incremental redundancy (IR) group for the UE, which is used to transmit information in a HARQ-like fashion to the UE. Because interference is reduced, the UE can decode the information at a lower coding rate and higher coding gain.

  • Patent number: 9143364
    Abstract: The present disclosure is described in the exemplary context of a Long Term Evolution (LTE) cellular network and is directed to a method and apparatus for estimating a gain and phase imbalance between an in-phase path and a quadrature path of a receiver operating in such a network. The method and apparatus specifically exploit channel coherence in time and frequency, and the properties of the Primary Synchronization Signal (PSS), and/or the Secondary Synchronization Signal (SSS), and/or information in the Physical Broadcast Channel (PBCH), all of which are defined by the LTE standard, to estimate the gain and phase imbalance of the receiver while it remains connected to a base station to receive data.
