Two homochiral Eu and Sm enantiomeric pairs showing circularly polarized luminescence, photoluminescence and triboluminescence.

Two homochiral EuIII and SmIII tris(β-diketonate) enantiomeric pairs, based on fluorinated β-diketone (Hbtfa) and enantiopure asymmetric N,N'-donor ligands (LR and LS), Λ-Eu(btfa)3LR (R-1-Eu)/Δ-Eu(btfa)3LS (S-1-Eu) and Λ-Sm(btfa)3LR (R-2-Sm)/Δ-Sm(btfa)3LS (S-2-Sm) (btfa- = 4,4,4-trifluoro-1-phenyl-1,3-butanedionate and LR/LS = (-)/(+)-4,5-pineno-2,2'-bipyridine) were synthesized. The electronic circular dichroism (ECD) spectra confirmed their enantiomeric nature. R-1-Eu/S-1-Eu and R-2-Sm/S-2-Sm exhibit intense characteristic emissions of EuIII (red) and SmIII (orange-red) ions both in the solid state and in DCM with long lifetimes and high luminescence quantum yields.

Biomarkers for hepatitis B virus replication: an overview and a look to the future.

Introduction: Hepatitis B virus (HBV) infection is a major public health issue but there are no powerful drugs to eradicate the virus. HBV markers including HBsAg, HBcrAg, HBV RNA, HBcAb, and HBV DNA are becoming promising biomarkers to reflect the natural phases of chronic HBV infection and predict the outcome of anti-HBV treatment.

Areas Covered: The authors summarized the biomarkers of HBV replication and presented the current advances of these biomarkers on predicting the outcome of anti-HBV treatment and identifying the progression of chronic HBV infection.

Synthesis of amide derivatives containing capsaicin and their antioxidant and antibacterial activities.

The capsaicin in hot peppers is an important biological active substance that is widely used in food and medicine. In this work, six capsaicin derivatives such as N-(4-Hydroxy-3-acetophenone benzyl)acrylamide (A), 2-hydroxy-3-(octyloxy)phenyl-5-acrylamidemethylbenzene phenyl methanone (B), N-(2,5-dihydroxybenzene)acetamide (C), N-(5-acetamidemethyl benzene-2,4-dihydroxybenzene)acetamide (D), 4-acetamideme thylbenzene-2-benzylphenol (E), and N-(2-methyl-4-hydroxy-5-methylthiobenzene)acetamide (F) were synthesized via the Friedel-Crafts (F-C) alkylation reaction and were characterized using IR, H NMR, and HRMS. The antioxidant activity of compounds was evaluated using the reducing power and DPPH radical (DPPH·) scavenging assays, and Vitamin C (Vc) was used as a control.

Plasma diamine oxidase level predicts 6-month readmission for patients with hepatitis B virus-related decompensated cirrhosis.

Background And Aims: Hepatitis B virus-related decompensated cirrhosis is difficult to cure but has a high readmission rate due to multiple complications. Our aim was to investigate the diagnostic potential value of plasma diamine oxidase (DAO) for 6-month readmission of patients with HBV-related decompensated cirrhosis.

Methods: A total of 135 patients with HBV-related decompensated cirrhosis were prospectively collected at the onset of discharge of hospital, and then were followed up for at least 6 months with the readmission as the primary outcome.

Syntheses, structures and catalytic properties of Evans-Showell-type polyoxometalate-based 3D metal-organic complexes constructed from the semi-rigid bis(pyridylformyl)piperazine ligand and transition metals.

Herein, two novel Evans-Showell-type polyoxometalate (POM)-based metal-organic complexes, namely, {[Cu(L)(H2O)3][Cu(L)0.5(H2O)][Cu(L)0.5(H2O)4][Co2Mo10H4O38]}·5H2O (1) and [(H2L)0.

Evans-Showell-type polyoxometalate-based metal-organic complexes with novel 3D structures constructed from flexible bis-pyrazine-bis-amide ligands and copper metals: syntheses, structures, and fluorescence and catalytic properties.

Two new Evans-Showell-type polyoxometalate (POM)-based metal-organic complexes, namely {Cu3(L1)1.5(H2O)5[Co2Mo10H4O38]}·5H2O (1), {[Cu(L2)0.5(H2O)2]2[Co2Mo10H4O38]}·6H2O (2) (L1 = N,N'-bis(2-pyrazinecarboxamide)-1,4-butane, L2 = N,N'-bis(2-pyrazinecarboxamide)-1,6-hexane), were successfully synthesized and structurally characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy, powder X-ray diffraction (PXRD) and thermogravimetric analyses (TGA).

Plasma concentration of diamine oxidase (DAO) predicts 1-month mortality of acute-on-chronic hepatitis B liver failure.

Background: Acute-on-chronic hepatitis B liver failure (ACHBLF) has high 1-month mortality but it is difficult to predict. This present study was aimed to determine the diagnostic value of plasma diamine oxidase (DAO) in predicting the 1-month mortality of ACHBLF.

Methods: A total of 106 consecutive newly diagnosed ACHBLF patients were retrospectively collected.

[The analysis of IL-10 and its methylation in the patients with acute on chronic liver failure].

Objective: To investigate the effect of IL-10 and the methylation of its promoter in acute on chronic liver failure (ACLF).

Methods: Patients were divided into three groups: 25 with ACLF, 25 with CHB, 10 healthy controls. Respectively detect the serum level of IL-10 via ELISA, and the methylation of IL-10 promoter via MSP, to analyze the difference among the three groups.

Enhanced demethylation of interferon-γ gene promoter in peripheral blood mononuclear cells is associated with acute-on-chronic hepatitis B liver failure.

Acute-on-chronic hepatitis B liver failure (ACHBLF) refers to liver failure occurring in patients with chronic hepatitis B (CHB) related liver diseases. Interferon-γ (IFN-γ) plays an important role in the exacerbation of liver function. However, the exact mechanism, by which IFN-γ mediates ACHBLF, is not fully understood.
