2-(1H-Benzotriazol-1-yl)-1-(4-ethyl­benzo­yl)ethyl 2-chloro­benzoate

In the crystal structure of the title compound, C24H20ClN3O3, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into chains extended along the a axis. The crystal studied was found to be an inversion twin

5-(2-Fluoro­benzyl­idene)-2,2-dimethyl-1,3-dioxane-4,6-dione

The title compound, C13H11FO4, was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 2-fluoro­benzaldehyde in ethanol. In the crystal structure, mol­ecules are linked into chains by weak inter­molecular C—H⋯O hydrogen bonds

2-(1H-Benzotriazol-1-yl)-1-(2-fluoro­benzo­yl)ethyl 4-methyl­benzoate

In the crystal structure of the title compound, C23H18FN3O3, inter­molecular C—H⋯N hydrogen bonds link the mol­ecules into chains extended along the c axis. The packing is further stabilized by weak C—H⋯O and C—H⋯F inter­actions. The F atom is disordered over two equally occupied 1- and 5-positions of the benzene ring

Fermionic phase transition induced by the effective impurity in holography

We investigate the holographic fermionic phase transition induced by the effective impurity in holography, which is introduced by massless scalar fields in Einstein-Maxwell-massless scalar gravity. We obtain a phase diagram in $(\alpha, T)$ plane separating the Fermi liquid phase and the non-Fermi liquid phase.Comment: 17 pages, 9 figure

Efficacy of nucleoside analogues on hepatitis B virus-related liver failure: A network meta-analysis

The purpose of this study was to compare the efficacy of nucleoside analogues (NAs) in the treatment of HBV-related liver failure. The data of patients with HBV-related liver failure treated with nucleoside analogues were used to conduct a network meta-analysis. A total of 1660 patients from 12 articles about the efficacy of lamivudine, entecavir, telbivudine and tenofovir for HBV-related liver failure treatment were recruited in the study. The highest two- and three-month survival rate was recorded for patients using tenofovir. The end-stage liver disease (MELD) score and mortality in patients undergoing tenofovir treatment were the lowest. Patients treated with telbivudine had the highest one-month survival rate. Patients receiving enticavir therapy showed the lowest HBV DNA level. Our results indicate that tenofovir may be the best therapy for the treatment of HBV-related liver failure compared to other nucleoside analogues (including lamivudine, entecavir and telbivudine) and non-NAs treatment

3-(4-Meth­oxy­benzyl­idene)-1,5-dioxa­spiro­[5.5]undecane-2,4-dione

In the title mol­ecule, C17H18O5, which was prepared by the reaction of (R)-1,5-dioxaspiro­[5.5]undecane-2,4-dione and 4-meth­oxy­benzaldehyde with ethanol, the 1,3-dioxane ring is in a distorted envelope conformation with the spiro C atom forming the flap. The crystal structure is stabilized by weak inter­molecular C—H⋯O hydrogen bonds
