  • Publication number: 20240121813
    Abstract: Implementations disclosed describe wireless devices and methods for mitigating aggressive medium reservations. A first wireless device comprises a transceiver and a processor coupled to the transceiver. The processor is to detect, within a first transmission received by the transceiver from a second wireless device via a first wireless communication channel, a pattern of medium reservations comprising a reservation duration that satisfies a threshold duration value. The processor is further to cause, in response to detecting the pattern of medium reservations, the transceiver to send a second transmission to an access point (AP) wireless device. The second transmission includes an indication of the pattern of medium reservations. The processor is further to detect a medium reservation mitigation signal within a third transmission received by the transceiver from the AP wireless device.

  • Publication number: 20230097253
    Abstract: The present inventors have arrived at the present application by confirming that a novel quinazolinone derivative exhibits therapeutic efficacy for metabolic disorders. The quinazolinone derivative according to the present application has a similar structure to that of idelalisib, but exhibits very different properties and a different mechanism of action from idelalisib. In addition, this derivative molecule was shown to have excellent efficacy against metabolic disorders, in particular lipid metabolic disorders, through different mechanism of action. The derivative molecule also showed excellent efficacy against non-alcoholic steatohepatitis (NASH). No non-alcoholic steatohepatitis treatment drugs have been approved at the time of filing.
