Boosting of the piezoelectric photocatalytic performance of BiMoO by Fe doping and construction S-scheme heterojunction using WO.

Although self-polarized piezoelectric semiconductor photocatalysts significantly enhance the separation of internally generated photocarriers, their photocatalytic performance is constrained by insufficient internal polarisation and a wide bandgap. Additionally, the low concentration of oxygen in contaminated water limits the effectiveness of such photocatalysts. To the best of our knowledge, this study was the first to determine that the piezoelectric properties of BiMoO (BMO), was due to the polarisation displacement of the MoO octahedron that occurred along the x-axis, as revealed through density functional theory (DFT) calculations.

Comparative analysis of the synergetic effects of Diwuyanggan prescription on high fat diet-induced non-alcoholic fatty liver disease using untargeted metabolomics.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver disorders worldwide and had no approved pharmacological treatments. Diwuyanggan prescription (DWYG) is a traditional Chinese medicine preparation composed of 5 kinds of herbs, which has been used for treating chronic liver diseases in clinic. Whereas, the synergistic mechanism of this prescription for anti-NAFLD remains unclear.

Changes in Triterpenes in after Processing Based on Targeted Metabolomics Using UHPLC-QTOF-MS/MS.

(AR) has been used as an herbal medicine in China for over a thousand years. Crude AR, salt-processed AR (SAR), and bran-processed AR (BAR) are recorded in the Pharmacopoeia of the People's Republic of China. However, the differences of chemical composition between crude AR and its processing products remain limited.

Efficacy and safety of a new disposable percutaneous positioning device invented to facilitate the precision of percutaneous core needle lung biopsies: a prospective, open and randomized controlled study.

Background: A new disposable percutaneous positioning device was developed which permits adjustment of the fixing puncture angle while performing a percutaneous core needle lung biopsy (CNLB). The aim of the study was to explore the positioning accuracy and clinical safety of the new device during CT-guided percutaneous CNLB.

Methods: A prospective, open and randomized controlled study with two parallel groups was conducted on 150 patients with pulmonary nodules between July 1, 2018 and June 30, 2019 including 101 males and 49 females who were divided (allocation ratio: 1:1) into a standard CNLB group without the percutaneous positioning device (control, n=75) and a new percutaneous positioning device group combined with CNLB (experimental, n=75).

Protoporphyrin IX catalyzed hydrogen peroxide to generate singlet oxygen.

Aim: To study the role of protoporphyrin IX (pPIX) in mitochondrial metabolism of hydrogen peroxide (H2O2).

Methods: O2 (-) specific fluorescent markers DMA (9,10-dimerthylanthracence) and SOSG (Singlet Oxygen Sensor Green reagent) were used for measurement of singlet oxygen ((1)O2). Catalyzing conversion of H2O2 into (1)O2 by pPIX was monitored in vitro under varied H2O2 content, temperature, and PH value in the reaction.
