The co-administration of DEX with mifepristone effectively suppressed the depressive-like symptoms caused by chronic treatment with DEX. Our results provided further evidence for a relationship between GR and depression and suggest that the pharmacological blockade of GR may increase the effectiveness of conventional pharmacotherapies used to treat depression.Although distigmine is known to sometimes cause severe adverse drug reactions (ADRs), such as cholinergic crisis, there are limited data on the risk factors for these ADRs. In this study, we defined a serum cholinesterase (sChE) cutoff level for early detection of ADRs to distigmine and sought to identify risk factors for these ADRs based on this value. This retrospective cohort study included all patients who were prescribed distigmine and underwent measurement of sChE over a period of 8 years at Kaetsu Hospital. Ninety-three patients were included. The sChE cutoff level below which there was an increase in risk of ADRs was defined as 129 U/L based on the levels in patients who had ADRs by receiver operating characteristic analysis. The percentage of ADRs tended to increase with advancing chronic kidney disease (CKD) stage. Multivariate logistic regression analyses showed that a distigmine dose >0.1 mg/kg/d (odds ratio 3.19, 95% confidence interval 1.24-8.19) and age >85 years (odds ratio 3.04, 95% confidence interval 1.18-7.82) were positively associated with an sChE level ≤129 U/L. An sChE cutoff level of 129 U/L is a useful predictor of the risk of an ADR to distigmine, and dose per body weight, age, and CKD progression may pose potential risk of an ADR to distigmine. Therefore, for patients taking distigmine who have these risk factors, the risk of a severe ADR to distigmine can be reduced by decreasing the dose of distigmine and close monitoring of the sChE level.Our previous study reported that co-encapsulation of potent antioxidants astaxanthin (Asx) and capsaisin (Cap) into liposomes brought about synergistically higher antioxidative activity than the calculated additive activity of each single antioxidant encapsulating liposome. Based on the previous computational chemistry analysis, the synergistic effect was revealed to be resulted from intermolecular interactions between Asx, especially 3R,3'R-form of Asx stereoisomer (Asx-R), and Cap, by which changes of electronic states of the polyene moiety of Asx-R were induced. Although liposomes co-encapsulating Asx-R and Cap (Asx-R/Cap-Lipo) at an optimal ratio clearly showed synergistic antioxidative activity in vitro, it is unclear whether the effective antioxidative activity derived from intermolecular interaction between Asx-R and Cap is also exerted in vivo. Therefore, in this study, we investigated therapeutic potential of Asx-R/Cap-Lipo as an antioxidant formulation in vivo. For this purpose, we employed carbon tetrachloride (CCl4)-induced acute liver injury rat model, since CCl4 is known to cause oxidative damage in liver. CCl4 administration significantly increased the levels of aspartate transaminase (AST) and alanine aminotransferase (ALT). Intravenous combined administration of liposomes encapsulating Asx-R (Asx-R-Lipo) and liposomes encapsulating Cap (Cap-Lipo) significantly decreased CCl4-induced increase of AST and ALT levels. Importantly, the treatment with Asx-R/Cap-Lipo tended to show higher protective effect on acute liver injury than combined treatment with Asx-R-Lipo plus Cap-Lipo. These results suggest that co-encapsulated Asx-R and Cap in liposomal membranes could exert more effective antioxidative activities in vivo, and that Asx-R/Cap-Lipo would be a hopeful antioxidant formulation for treating reactive oxygen species-related diseases.Primary liver cancer is a lethal cancer. iJMJD6 manufacturer The phosphatidylinositol 3-kinase (PI3K)-Akt-mammalian target of rapamycin (mTOR) pathway has been implicated in the pathogenesis of liver cancer. Gomisin N (GN), a lignan isolated from the dried fruits of Schisandra chinensis (Turca.) Baill., has been reported to reduce viability of, and induce apoptosis in, HepG2 liver cancer cells. In preadipocytes, GN was found to inhibit Akt activity. In the present study, Akt signaling-related anti-liver cancer mechanisms of GN were investigated. We confirmed that GN reduces cell viability of, and triggers apoptosis in, more liver cancer cell lines. Mechanistic studies revealed that GN lowers protein levels of phospho-PI3K (p85 tyrosine (Tyr)458), phospho-Akt (serine (Ser)473), and Akt downstream molecules Mcl-1 in HepG2 and HCCLM3 cells. Meanwhile, GN activates mTOR and inhibits ULK1 (a negative downstream effector of mTOR) activities. Activation of mTOR has been reported to suppress ULK1 activity and repress autophagy. Indeed, we observed that GN inhibits autophagy in liver cancer cells. In summary, we for the first time demonstrated that GN inhibits the PI3K-Akt pathway and regulates the mTOR-ULK1 pathway in liver cancer cells.A genetically modified (GM) soybean kernel detection system using combination of DNA preparation from individual soybean kernels and event-specific real-time PCR was developed to simultaneously identify GM soybean events authorized for food after safety assessments in Japan. Over 100 kernels in the non-identity-preserved soybean samples imported from the United States of America (two U.S.A. lots) and Brazil (one lot) were randomly selected and examined. In total, 98 and 96% of the two independent U.S.A. lots, and 100% of the Brazilian lot contained GM soybean kernels. Herbicide-tolerant events, MON89788 (trade name Genuity® Roundup Ready 2 Yield™), GTS 40-3-2 (trade name Roundup Ready™ soybean) and A2704-12 (trade name Liberty Link® soybean), were detected similarly in both U.S.A. lots. In the Brazilian lot, in addition to GTS 40-3-2, a stacked GM event, MON87701 × MON89788, having insect-resistance and herbicide-tolerance, was detected. There were no unauthorized GM soybeans comingled, and the ratio of GM soybean events detected was consistent with statistical reports on the cultivated GM soybean events in both countries.Long-term combination treatment with lenalidomide and low-dose dexamethasone is important to achieve a curative effect in patients with multiple myeloma (MM). In this study, the plasma concentration of lenalidomide was measured at 3 h after oral administration, when the drug is in the elimination phase and can be easily measured in outpatients, to identify factors that may lead to the discontinuation of this combination therapy. Patients were assigned to continuation or discontinuation of therapy groups, and the baseline characteristics of patients, lenalidomide concentration, and concentration/dose (C/D) ratios reflecting oral clearance were compared between the two groups. The efficacy and severity of adverse events were also compared. The results showed that patients who discontinued or modified treatment had low plasma concentrations of lenalidomide and C/D ratios, indicating high oral clearance of lenalidomide. The estimated creatinine clearance rate was negatively correlated with the C/D ratio. The plasma concentrations of lenalidomide were independent from kidney function and differed significantly among patients.
