Preventable diagnostic errors of lower gastrointestinal perforation: a secondary analysis of a large-scale multicenter retrospective study.

Background: Lower gastrointestinal perforation (LGP) is an acute abdominal condition associated with a high mortality rate. Timely and accurate diagnosis is crucial. Nevertheless, a diagnostic delay has been estimated to occur in approximately one-third of the cases, and the factors contributing to this delay are yet to be clearly understood.

Allyl isothiocyanate suppressed periodontal tissue destruction in mice via bacteriostatic and anti-inflammatory activities against Porphyromonas gingivalis.

Objectives: Allyl isothiocyanate (AITC) is a phytochemical that is abundantly present in cruciferous vegetables, such as wasabi and mustard. Among its pharmacological properties, it demonstrates anticancer, antifungal, and anti-inflammatory activities. This study aimed to investigate the functions of AITC against periodontopathic bacteria and its effects on a mouse model of periodontitis.

TAK-861, a potent, orally available orexin receptor 2-selective agonist, produces wakefulness in monkeys and improves narcolepsy-like phenotypes in mouse models.

Narcolepsy type 1 (NT1) is associated with severe loss of orexin neurons and characterized by symptoms including excessive daytime sleepiness and cataplexy. Current medications indicated for NT1 often show limited efficacy, not addressing the full spectrum of symptoms, demonstrating a need for novel drugs. We discovered a parenteral orexin receptor 2 (OX2R) agonist, danavorexton, and an orally available OX2R agonist, TAK-994; both improving NT1 phenotypes in mouse models and individuals with NT1.

Antiviral effect of alkaloids-free Ephedra Herb extract on respiratory syncytial virus infection.

Respiratory syncytial virus (RSV) is a major cause of respiratory tract infection in children. Despite decades of efforts, no effective therapies are available. We recently reported that extracts of Ephedra Herb and Cinnamon Bark interacted with the G attachment protein of RSV to inhibit infectivity.
