Comparative Study on the Electrocatalytic Performance of ABO-Based Hexagonal Perovskite Oxides with Different [AO] Layers.

To systematically investigate the influence of the number of [AO] layers in the unit cell of hexagonal perovskite oxide on the oxygen evolution reaction performance, we successfully synthesized the three new hexagonal perovskite oxides 2H-BaCoRuO, 6H-BaCoRuO, and 10H-BaCoRuO with the same element composition but different [BaO] layers via the sol-gel method. Here, 2H, 6H, and 10H refer to the number of [BaO] layers contained in the unit cell of the BaCoRuO system. Experimentally, 10H-BaCoRuO, featuring ten layers of [BaO], exhibits optimal electrochemical activity among the three oxide catalysts, and in situ Raman results under various bias voltages confirm its ability to maintain a high surface crystal structural stability.

Automatic AI tool for opportunistic screening of vertebral compression fractures on chest frontal radiographs: A multicenter study.

Vertebral compression fractures (VCFs) are the most common type of osteoporotic fractures, yet they are often clinically silent and undiagnosed. Chest frontal radiographs (CFRs) are frequently used in clinical practice and a portion of VCFs can be detected through this technology. This study aimed to develop an automatic artificial intelligence (AI) tool using deep learning (DL) model for the opportunistic screening of VCFs from CFRs.

Study on Water Splitting of the 214-Type Perovskite Oxides LnSrCoO (Ln = La, Pr, Sm, Eu, and Ga).

We present a study on the electrocatalysis of 214-type perovskite oxides LnSrCoO (Ln = La, Pr, Sm, Eu, and Ga) with semiconducting-like behavior synthesized using the sol-gel method. Among these five catalysts, PrSrCoO exhibits the optimal electrochemical performance in both the oxygen evolution reaction and the hydrogen evolution reaction, mainly due to its larger electrical conductivity, mass activity, and turnover frequency. Importantly, the weak dependency of LSV curves in a KOH solution with different pH values, revealing the adsorbate evolving mechanism in PrSrCoO, and the density functional theory (DFT) calculations indicate that PrSrCoO has a smaller Gibbs free energy and a higher density of states near the Fermi level, which accelerates the electrochemical water splitting.

DeepKOA: a deep-learning model for predicting progression in knee osteoarthritis using multimodal magnetic resonance images from the osteoarthritis initiative.

Background: No investigations have thoroughly explored the feasibility of combining magnetic resonance (MR) images and deep-learning methods for predicting the progression of knee osteoarthritis (KOA). We thus aimed to develop a potential deep-learning model for predicting OA progression based on MR images for the clinical setting.

Methods: A longitudinal case-control study was performed using data from the Foundation for the National Institutes of Health (FNIH), composed of progressive cases [182 osteoarthritis (OA) knees with both radiographic and pain progression for 24-48 months] and matched controls (182 OA knees not meeting the case definition).

Prediction model for knee osteoarthritis using magnetic resonance-based radiomic features from the infrapatellar fat pad: data from the osteoarthritis initiative.

Background: The infrapatellar fat pad (IPFP) plays an important role in the incidence of knee osteoarthritis (OA).

In this study, we aimed to investigate whether the IPFP radiomic features have predictive value for incident radiographic knee OA (iROA) 1 year prior to iROA diagnosis.

Electrochemical performance of CoSe with mixed phases decorated with N-doped rGO in potassium-ion batteries.

Potassium-ion batteries (PIBs) have received much attention as next-generation energy storage systems because of their abundance, low cost, and slightly lower standard redox potential than lithium-ion batteries (LIBs). Nevertheless, they still face great challenges in the design of the best electrode materials for applications. Herein, we have successfully synthesized nano-sized CoSe encapsulated by N-doped reduced graphene oxide (denoted as CoSe@N-rGO) by a direct one-step hydrothermal method, including both orthorhombic and cubic CoSe phases.

Hexagonal perovskite Sr(CoFe)O as an efficient electrocatalyst towards the oxygen evolution reaction.

The high overpotential required for the oxygen evolution reaction (OER)-due to the transfer of four protons and four electrons-has greatly hindered the commercial viability of water electrolysis.

In this study, we report the application of Sr(CoFe)O (SCF-H) perovskite oxide with a hexagonal phase structure in the field of OER electrocatalysis.

Effects of a single transient transfection of Ten-eleven translocation 1 catalytic domain on hepatocellular carcinoma.

Tumor suppressor genes (TSGs), including Ten-eleven translocation 1 (TET1), are hypermethylated in hepatocellular carcinoma (HCC). TET1 catalytic domain (TET1-CD) induces genome-wide DNA demethylation to activate TSGs, but so far, anticancer effects of TET1-CD are unclear. Here we showed that after HCC cells were transiently transfected with TET1-CD, the methylation levels of TSGs, namely APC, p16, RASSF1A, SOCS1 and TET1, were distinctly reduced, and their mRNA levels were significantly increased and HCC cells proliferation, migration and invasion were suppressed, but the methylation and mRNA levels of oncogenes, namely C-myc, Bmi1, EMS1, Kpna2 and c-fos, were not significantly change.

In this study, we chose circRNA0003906 as a targeted circRNA to evaluate its expression pattern and clinical value in CRC patients.

Stomach desmoid tumor: a case report and review of the literature.

Desmoid tumors, also known as aggressive fibromatoses, are clinically rare soft-tissue tumors that arise from such connective tissues as the musculoaponeurotic structures. The majority of the reported intra-abdominal desmoid tumors occur in the small intestinal mesentery and peritoneum, whereas stomach desmoid tumors are extremely rare. The present study reports a case of stomach desmoid tumor and reviews the related available literature.
