  • Patent number: 12152051
    Abstract: A cyclic dinucleotide analogue, a pharmaceutical composition thereof, and application. A cyclic dinucleotide analogue (I), an isomer thereof, a prodrug, a stable isotope derivative, or a pharmaceutically acceptable salt has the following structure. The cyclic dinucleotide analogue can be used as a regulator of a stimulator of interferon genes (STING) and a related signal path thereof, and can effectively treat and/or relieve multiple types of diseases, including but not limited to malignant tumors, inflammations, autoimmune diseases, and infectious diseases. In addition, the STING regulator can also be used as a vaccine adjuvant.

  • Patent number: 8704785
    Abstract: A haptic feedback apparatus includes a screen and a piezoelectric vibrator partially connected with the screen. The screen comprises a display viewing area and a frame surrounding the display viewing area. The piezoelectric vibrator engaged with the screen defines a moving portion having a projecting portion extending from one distal end of the moving portion toward the screen. Wherein, the screen defines a cavity and the projecting portion of the piezoelectric vibrator is at least partially accommodated in the cavity. The manufacture of the haptic feedback apparatus is simple and low-cost.

  • Patent number: 8325024
    Abstract: Disclosed is an apparatus used in an electronic device for providing haptic feedback. The apparatus includes a base defining a receiving space, a piezoelectricity vibrator suspended in the receiving space and being capable of vibrating in the receiving space, a pair of contacts partially accommodated in the base and electrically connected to the piezoelectricity vibrator, and a transmitting mass located above the piezoelectricity vibrator with a lower side abutting against the piezoelectricity vibrator.

  • Publication number: 20120264139
    Abstract: This invention concerns a bioaffinity assay for quantitative determination in a sample of free PAPP-A, defined as the pregnancy associated plasma protein A (PAPP-A) that is not complexed to the proform of major basic protein (proMBP), wherein free PAPP-A is determined either i) as a calculated difference between measured total PAPP-A and measured PAPP-A complexed to proMBP, or ii) by a direct bioaffinity assay measuring only free PAPP-A. Furthermore, the invention concerns a method for diagnosing an acute coronary syndrome in a person by using as marker either free PAPP-A as such or a ratio free PAPP-A/total PAPP-A, free PAPP-A/PAPP-A complexed to proMBP, or PAPP-A complexed to proMBP/total PAPP-A.
