Strong Electronic Interaction in High-Entropy Oxide Enhances Oxygen Evolution Reaction.

High-entropy oxides are a new type of material with significant application potential. However, the lack of a universal HEO preparation method severely limits the property study and application of HEOs. Herein, we report a universal approach of spray pyrolysis for the preparation of various HEOs and study the electrocatalytic performance of HEOs toward the oxygen evolution reaction.

Unveiling the Effect of Organic Sulfur Sources on Synthesized MoS Phases and Electrocatalytic Hydrogen Evolution Performances.

Metallic-phase MoS exhibits Pt-comparable electrocatalytic hydrogen evolution reaction (HER) performance in acidic conditions. However, the controllable synthesis of metallic-phase MoS is quite challenging because the key factor determining the phase types of MoS during synthesis is still unclear. Herein, the effect of organic sulfur sources on the formed MoS phase is studied by use of thioacetamide (TAA), l-cysteine, and thiourea as sulfur sources.

Protective effect and mechanism of polyphenols against acrylamide-induced neurotoxicity.

This study aimed to investigate the potential neuroprotective effects of polyphenols (LRP) against acrylamide (ACR)-induced neurotoxicity and the mechanism of action and LRP treatment significantly attenuated ACR-induced cytotoxicity in SH-SY5Y cells in a dose-dependent manner. LRP treatment increased the nuclear factor erythroid-2-related factor 2 (Nrf2) protein and subsequent activation of downstream proteins in SH-SY5Y cells. LRP treatment down-regulated the expression of relevant apoptotic proteins, including JNK, P-JNK, P38, P-P38, and caspase 3 in ACR-induced cells.

Atomically Dispersed Fe-N Sites and NiFe-LDH Sub-Nanoclusters as an Excellent Air Cathode for Rechargeable Zinc-Air Batteries.

The sluggish four-electron processes of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) limit the development of rechargeable Zn-air batteries (RZABs). Highly efficient ORR/OER bifunctional electrocatalysts are therefore highly desired for the commercialization of RZABs in large scale. Herein, the Fe-N-C (ORR active sites) and NiFe-LDH clusters (OER active sites) are successfully integrated within a NiFe-LDH/Fe,N-CB electrocatalyst.

Dietary exposure to acrylamide of university students in Ningxia of Northwest China and the effect on their neurobehavioral performance and oxidative stress in serum.

This study aims to investigate dietary exposure to acrylamide (AA) and also make an assessment of its effect on the neurobehavioral performance and oxidative stress in the serum of university students in Ningxia. The place primarily consists of arid, dry desert, and wheat-based foods are the staple food there. A total of 803 university students in Ningxia participated in this cross-sectional study.

Efficacy of vitamin and antioxidant supplements for treatment of diabetic peripheral neuropathy: systematic review and meta-analysis of randomized controlled trials.

The results of treatment effect of vitamin or antioxidant intake on diabetic peripheral neuropathy (DPN) was inconsistent. Therefore, we performed a meta-analysis of randomized controlled trials (RCTs) to examine whether these supplements are effective in DPN treatment. We searched seven databases from inception to October 2021.

Protective Effect of Polyphenols on Oxidative Stress against Acrylamide Induced Liver Injury in Rats.

Acrylamide (ACR) is formed during tobacco and carbohydrate-rich food heating and is widely applied in many industries, with a range of toxic effects. The antioxidant properties of polyphenols (LRP) have been established before. This study aimed to research the protective effect of LRP against ACR-induced liver injury in SD rats.

Germacrone alleviates neurological deficits following traumatic brain injury by modulating neuroinflammation and oxidative stress.

Background: Germacrone (GM) is a terpenoid compound which is reported to have anti-inflammatory and anti-oxidative effects. However, its role in treating traumatic brain injury (TBI) remains largely unknown.

Methods: Male C57BL/6 mice were divided into the following groups: control group, TBI group [controlled cortical impact (CCI) model], CCI + 5 mg/kg GM group, CCI + 10 mg/kg GM group and CCI + 20 mg/kg GM group.

(Fe,N-codoped carbon nanotube)/(Fe-based nanoparticle) nanohybrid derived from Fe-doped g-CN: A superior catalyst for oxygen reduction reaction.

Transition metal- and N-codoped carbon nanotubes (CNTs) have superior catalytic activity because the curling surface enhances the bonding ability of atoms within CNTs to other species. However, it is a great challenge to prepare CNTs with transition metal- and N-doped at high level during the growth of CNTs. Here, (Fe,N-codoped CNT)/(Fe-based nanoparticle) (Fe,N-CNT/FeNP) hybrid nanostructures are for the first time prepared through the carbonization of Fe-doped g-CN.

Efficacy and safety of computer-assisted stereotactic transplantation of human retinal pigment epithelium cells in the treatment of Parkinson disease.

Objective: This study explores the efficacy and safety of computer-assisted stereotactic transplantation of human retinal pigment epithelium (hRPE) cells in the treatment of Parkinson disease (PD).

Methods: Guided by computed tomography and magnetic resonance imaging image mergence, we transplanted 4 × 10 hRPE cells into the putamina and lateral ventricles of 17 PD cases by stereotactic surgery. The transplantation site was located in the contralateral side of the symptoms and signs.
