TiN/anatase/rutile phase junction obtained by in-situ thermal transformation for efficient photothermal-assisted photocatalytic hydrogen generation.

Phase junctions exhibit great potential in photocatalytic energy conversion, yet the narrow light response region and inefficient charge transfer limit their photocatalytic performance. Herein, an anatase/rutile phase junction modified by plasmonic TiN and oxygen vacancies (TiN/(A-R-TiO-Ov)) is prepared through an in-situ thermal transformation from TiN for efficient photothermal-assisted photocatalytic hydrogen production for the first time. The content of TiN, oxygen vacancies, and phase components in TiN/(A-R-TiO-Ov) hybrids can be well-adjusted by tuning the heating time.

A real-world case-control study on the efficacy and safety of pulsed field ablation for atrial fibrillation.

Objective: The primary objective of this study was to evaluate the efficacy and safety of pulsed field ablation in individuals diagnosed with atrial fibrillation.

Methods: A total of 36 patients diagnosed with atrial fibrillation were enrolled in the pulsed field ablation group, while another 36 patients diagnosed with atrial fibrillation were included in the radiofrequency ablation group. Among the study participants, 15 patients in the pulsed field ablation group and 17 patients in the radiofrequency ablation group had persistent atrial fibrillation.

Use of machine learning method on automatic classification of motor subtype of Parkinson's disease based on multilevel indices of rs-fMRI.

Objective: This study aimed to develop an automatic classifier to distinguish different motor subtypes of Parkinson's disease (PD) based on multilevel indices of resting-state functional magnetic resonance imaging (rs-fMRI).

Methods: Ninety-six PD patients, which included thirty-nine postural instability and gait difficulty (PIGD) subtype and fifty-seven tremor-dominant (TD) subtype, were enrolled and allocated to training and validation datasets with a ratio of 7:3. A total of five types of index, consisting of mean regional homogeneity (mReHo), mean amplitude of low-frequency fluctuation (mALFF), degree of centrality (DC), voxel-mirrored homotopic connectivity (VMHC), and functional connectivity (FC), were extracted.

[Distribution of phosphorus in surface sediments from the Yellow River estuary wetland].

Surface sediments were collected from Yellow River estuary wetland. The distribution of phosphorus in sediments was analyzed with modified SEDEX. The results indicated that the contents of TP in surface sediments varied from 12.

[Construction of the eukaryotic expression vector containing rat transforming growth factor beta type II receptor and interferon gamma fusion genes].

Objective: To express a bioactive fusion protein comprising rat soluble transforming growth factor beta type II receptor and interferon gamma(rsTGFbetaR II-IFN gamma) in mammalian cells.

Methods: mRNA was extracted from rat liver and the sTGFbetaR II-IFN gamma genes amplified by RT-PCR, then the two gene segments were cloned into the same pSecTag2A expression vector, and pSecTag2A/rsTGFbetaR II-IFN gamma recombinant plasmid was obtained, which was later transfected into CHO cells using liposomes. The expression of pSecTag2A/rsTGFbetaR II-IFN gamma in the supernatant was detected by ELISA and Western blotting.

[Construction and expression of the eukaryotic expression vector containing human soluble transforming growth factor beta receptor II].

Objective: To construct a eukaryotic expression vector encoding the gene of extracellular region of type II transforming growth factor beta receptor (sTGFbetaR II), to express the protein in CHO cell line and to determine its biological activity.

Methods: The extracellular region (amino acids 1-159) of the human TGFbetaR II cDNA was amplified by PCR from a TGFbetaR II chimeric plasmid,and the eukaryotic expression plasmid pCDNA3.1/myc-his(-)B-sTGFbetaR II(pCDNA-sTGFbetaR II) was constructed by inserting the sTGFbetaR II cDNA into the EcoR I/Hind III-digested pCDNA.
