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. The phosphatidylinositol 3-kinase (PI3K)-Akt-mammalian target of rapamycin (mTOR) pathway has been implicated in the pathogenesis of liver cancer.
