Publication number: 20230158038Abstract: A method for treating an influenza virus infection is described. The disclosed method generally involves administering an effective amount of a compound, for example baloxavir marboxil, to a subject having an influenza virus infection and at least one complication risk factor. Generally, the amount is effective such that a reduction in a time to improvement of at leat one symptom of an influenza virus infection is statistically significant as compared to that of a non-treated subject.Type: ApplicationFiled: January 10, 2023Publication date: May 25, 2023Inventors: Takeki UEHARA, Keiko KAWAGUCHI, Ann WELL, Simon PORTSMOUTH

Patent number: 10991335Abstract: A display device according to the present disclosure includes: pixels arranged in a matrix; a data line group that includes a pair of data lines for each pixel column; a data line drive circuit that supplies a positive-phase data signal to one of the pair of data lines, and a negative-phase data signal to the other of the pair of data lines; and an auxiliary drive circuit that is provided for each pair of data lines, and that processes the positive-phase data signal and the negative-phase data signal, in which the auxiliary drive circuit has a dead zone in a region where there is no difference between a positive-phase potential and a negative-phase potential, or where the difference in potential is smaller than a predetermined value. An electronic apparatus according to the present disclosure includes a display device having the configuration described above.Type: GrantFiled: October 16, 2018Date of Patent: April 27, 2021Assignee: Sony Semiconductor Solutions CorporationInventors: Toshihiko Orii, Hiroshi Nakao, Naoki Andou, Kazuhiro Takeda, Keiko Kawaguchi
