Publication number: 20210231036Abstract: The present disclosure provides a muffler system that can effectively reduce exhaust noises. The muffler system includes an exhaust passage and a first muffler. The exhaust passage is configured to allow a flow of an exhaust gas. The first muffler is an expansion chamber muffler and disposed in the exhaust passage. The first muffler is situated upstream of a first position in a flow direction of the exhaust gas. The first position is located away from an upstream end of the exhaust passage by one third of an entire length of the exhaust passage.Type: ApplicationFiled: January 8, 2021Publication date: July 29, 2021Inventors: Masahiro Kajikawa, Masaya Takeuchi, Masayuki Sudoh

Publication number: 20110160252Abstract: First, the present inventors assessed the effect of the compound represented by formula (III) below on Huh-7 cells infected with HBV, and demonstrated that the compound alone had an anti-HBV effect in vitro. Formula (III) Then, the present inventors revealed that the HBV replication-suppressing effect of PEG-IFN is enhanced in chimeric mice having a human liver infected with genotype C or A HBV when PEG-IFN is used in combination with the compound represented by formula (III) above. The present inventors also revealed that the HBV replication-suppressing effect of Entecavir is enhanced in chimeric mice having a human liver infected with genotype C HBV (wild-type and Entecavir-resistant strains) when Entecavir is used in combination with the compound represented by formula (III) above.Type: ApplicationFiled: June 18, 2009Publication date: June 30, 2011Inventors: Masashi Mizokami, Yasuhito Tanaka, Masaya Sugiyama, Masayuki Sudoh
