A review on defect modulated electrocatalysts for the oxygen evolution reaction.

The oxygen evolution reaction (OER) is crucial for applications such as water splitting and rechargeable metal-air batteries. Recent research has focused on improving the activity and stability of OER electrocatalysts through various strategies including structural innovation, heteroatom doping, and conductivity enhancement. Among these, defect engineering has proved particularly effective, allowing precise modulation of the materials' electronic structure at the atomic level.

Background: The liver is a key target organ for colorectal and gastric cancer metastasis. One of the challenges in the treatment of colorectal and gastric cancers is the management of liver metastasis. This study aimed to investigate the efficacy, adverse effects, and coping strategies of oncolytic virus injection in patients with liver metastases of gastrointestinal malignancies.

Comparative efficacy for different age groups of psychological or psychosocial treatments on post-traumatic stress disorder: protocol for systematic review, meta-analysis and meta-regression analysis.

Introduction: It remains unknown whether psychological or psychosocial treatments for post-traumatic stress disorder (PTSD) have comparable effects across the life span. This study aims at comparing the effects of psychological/psychosocial treatments for PTSD between different age groups of youth, early-middle adults and late adults.

MOF-Derived Iron-Cobalt Bimetallic Selenides for Water Electrolysis with High-Efficiency Oxygen Evolution Reaction.

Highly active and stable oxygen evolution reaction (OER) electrocatalysts for water electrolysis are currently in high demand. Herein, a rationally designed three-dimensional (3D) CoFe selenide porous array (Fe-CoSe PA) is synthesized through ion exchange from zeolitic imidazolate framework-L (ZIF-L) nanoarray, followed by a facile selenization under hydrothermal conditions for OER electrocatalysis. During the OER process, the surface of Fe-CoSe PA is rapidly oxidized to CoFe oxides/hydroxides, which prevents the inner layer from being oxidized.

Insulin-like growth factor reduced against decabromodiphenyl ether-209-induced neurodevelopmental toxicity in vivo and in vitro.

Objective: How to reduce the neurodevelopmental toxicity of decabromodiphenyl ether PBDE-209 remains unclear. This study investigated neurodevelopmental toxicity of PBDE-209 and the protective effects of insulin-like growth factor-1 (IGF-1).

Methods: Pregnant Sprague-Dawley rats were treated with PBDE-209 and IGF-1, and the offspring were subjected to the Morris Water Maze test.

Hericium erinaceus is a popular culinary and medicinal mushroom in China because of its broad beneficial effects. In this study we evaluated the effects of stimulation with 7 growth regulators at 5 different concentrations on improving the production of nutritional and bioactive compounds by H. erinaceus.

miR-422a inhibits osteosarcoma proliferation by targeting BCL2L2 and KRAS.

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. However, the underlying mechanism of osteosarcoma carcinogenesis and progression remains unknown. In the present study, we evaluated the expression profile of miRNAs in osteosarcoma tissues and the adjacent normal tissues.

Increased expression of microRNA-148a in osteosarcoma promotes cancer cell growth by targeting PTEN.

Osteosarcoma is the most common type of primary malignant bone tumor, and deregulated microRNAs (miRNAs or miRs) in osteosarcoma have attracted great attention. In the present study, through miRNA microarray analysis, it was identified that miR-148a expression was significantly increased in osteosarcoma tissues. Increased miR-148a expression was significantly correlated with tumor progression and prognosis.

miR-106a-5p Suppresses the Proliferation, Migration, and Invasion of Osteosarcoma Cells by Targeting HMGA2.

We aim to investigate the effect of miR-106a-5p on the proliferation, migration, and invasion of osteosarcoma (OS) cells by targeting high-mobility group AT-hook 2 (HMGA2). Real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) was used for detecting the expressions of miR-106-5p and HMGA2 in 137 OS and adjacent normal bone tissues. Immunohistochemistry was applied for the HMGA2 protein expression detection.
