  • Publication number: 20220291217
    Abstract: Exosomes were purified from the sera of patients with gastric cancer and healthy subjects by using size-exclusion chromatography, and novel markers were obtained through mass spectrometry. In the patients with gastric cancer, 40 proteins with enhanced expression and 4 proteins with decreased expression can be suitable markers for detecting gastric cancer. Particularly, the detailed analysis of CA1, including its function, showed that gastric cancer could be detected with high sensitivity.

  • Patent number: 11384507
    Abstract: A turn-drive apparatus capable of securing high acceleration at the time of turning start with a reduced relief loss includes a hydraulic pump of a variable capacity type, a turning motor, a turning control device, a relief valve, and a flow rate control device that controls a pump flow rate. The flow rate control device calculates a relief-cut-control target pump flow rate on the basis of the sum of a minimum relief flow rate and a turning-speed flow rate, and inputs a pump capacity command to the variable capacity-type hydraulic pump based thereon. The flow rate control device makes the relief-cut-control target pump flow rate larger than the sum of the minimum relief flow rate and the turning-speed flow rate at the time of turning start.
