Osteoporosis (OP) is considered as one of the major comorbidities rheumatoid arthritis (RA), and responsible for fragility fracture. However, there currently no effective treatment RA complicated with OP. Tubson-2 decoction (TBD), a Mongolian medicine also known Erwei Duzhong Decoction, has been shown to exert preventive effect on post-menopausal osteoporosis (PMOP). The effects TBD RA-induced OP, well bioactive compound underlying mechanisms, remain be elucidated.To explore OP in vivo,...

We recently found that butyrate could ameliorate inflammation of alcoholic liver disease (ALD) in mice. However, the exact mechanism remains incompletely comprehended. Here, we examined role on ALD-associated through macrophage (Mψ) regulation and polarization using vivo vitro experiments. For experiments, C57BL/6J mice were fed modified Lieber-DeCarli liquid diets supplemented with or without ethanol sodium (NaB). After 6 weeks treatment, euthanized associated indicators analyzed....

1. Niclosamide is an old anthelmintic drug that shows potential in fighting against cancers. Here, we characterized the metabolism of niclosamide by cytochrome P450 enzymes (CYPs) and UDP-glucuronosyltransferases (UGTs) using human liver microsomes (HLM) expressed enzymes.2. NADPH-supplemented HLM (and from various animal species) generated one hydroxylated metabolite (M1) niclosamide; UDPGA-supplemented mono-O-glucuronide (M2). The chemical structures M1 (3-hydroxy niclosamide) M2...
