  • Patent number: 10285846
    Abstract: Disclosed herein is a urethral catheter with an anti-infection structure for infants in which, in a state in which a hose is combined with a main pipe in advance, the reinforcement rod is inserted into/released from a urethral insertion pipe through a reinforcement rod inflow and outflow pipe separately formed at one side of the main pipe to prevent leakage of urine. When the reinforcement rod is inserted into the urethral insertion pipe in the combined state of the hose with the urethral insertion pipe and is then released from the urethral insertion pipe, setting of a urine storage bag is completed, thereby shortening a time to install of the urine storage bag, reducing medical staff's trouble, and preventing contamination and infection of a patient and the medical staff due to leakage of urine from the bag to the outside.

  • Patent number: 10131888
    Abstract: A secretion signal peptide sequence (SP) in combination with a cleavage inhibition sequence (CIS) fused to a structural gene sequence in a recombinant expression system can be used to express a full length protein with an SP in a cell. Such a fusion protein may be purified to homogeneity from a membrane fraction of the cell. The SP in combination with the CIS is a protein transduction domain that exhibits superior intracellular protein transduction efficiency when the SP precedes the CIS in a N to C-terminus direction.

  • Patent number: 10055829
    Abstract: A thickness of a first layer in a structure may be measured based on an original image of the structure. A first boundary of the first layer may be identified in the original image. A second boundary that is substantially indistinguishable in the original image may be identified based on converting the original image into a first image based on the first boundary and generating a second image based on filtering the first image. The first image may be generated based on adjusting partial image portions of the original image to align the representation of the first boundary with an axis line, such that the first image includes a representation of the first boundary that extends substantially in parallel with the axis line. The second boundary may be identified from the second image, and the thickness of the layer may be determined based on the identified first and second boundaries.
