Sex difference in alexithymia and cognitive impairment in chronic schizophrenia: a large sample study based on Chinese Han population.

Sex differences in schizophrenia have been noted across domains such as alexithymia and cognitive function; however, how they interact remains unclear. This study aimed to explore sex differences in the relationship between alexithymia and cognitive function in patients with chronic schizophrenia. A total of 695 patients (464 males and 231 females) who met the DSM-IV diagnostic criteria for schizophrenia were recruited in this cross-sectional study.

Modulation in Spin State of CoO Decorated Fe Single Atom Enables a Superior Rechargeable Zinc-Air Battery Performance.

High-performance bifunctional electrocatalyst for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) is the keystone for the industrialization of rechargeable zinc-air battery (ZAB). In this work, the modulation in the spin state of Fe single atom on nitrogen doped carbon (Fe-NC) is devised by CoO (CoO@Fe-NC), and a mediate spin state is recorded. Besides, the d band center of Fe is downshifted associated with the increment in e filling revealing the weakened interaction with OH moiety, resulting in a boosted ORR performance.

Cobalt Incorporation Promotes CO Desorption from Nickel Active Sites Encapsulated by Nitrogen-Doped Carbon Nanotubes in Urea-Assisted Water Electrolysis.

The potential application prospects of urea-assisted water electrolysis toward hydrogen production in renewable energy infrastructure can effectively alleviate energy shortages and environmental pollution caused by rich urea wastewater. It is of prominent significance that adjusting the CO desorption of nickel-based electrocatalysts can overcome the slow reaction kinetics for urea oxidation reaction (UOR) to achieve exceptional catalytic activity. In this work, cobalt (Co) metal doping is employed to boost the UOR performance of nitrogen-doped carbon nanotubes encapsulating nickel nanoparticle electrocatalysts (Ni@N-CNT).

Hydrogen spillover for boosted catalytic activity towards hydrazine oxidation.

A nanoflower-like MoO-Rh electrocatalyst exhibits a 3.5-fold higher mass activity in the hydrazine oxidation reaction compared with metallic Rh, attributed to the hydrogen spillover, acting as a hydrogen pump to deplete hydrogen from the Rh active site.

Risk factors of complications after thermal ablation for hepatocellular carcinoma: the role of assessment of liver background.

Objective: To use an elastography technology and other clinical and radiological data for assessment of liver background and analyze risk factors of complications after thermal ablation in patients with hepatocellular carcinoma.

Methods: Demographics, laboratory analyses, and radiological characteristics were collected from all patients. Main elastography-related indicators included F index (fibrosis index), A index (inflammation index), ATT (attenuation coefficient), E (kPa), AREA (area of blue parts), and CORR (correlation).

Utilizing press needle acupuncture to treat mild-to-moderate COVID-19: A single-blind, randomized controlled trial.

Background: In China, acupuncture has been employed as an adjunctive therapy for coronavirus disease 2019 (COVID-19). Press needle acupuncture is a special type of acupuncture that provides prolonged stimulation to acupuncture points and simultaneously reduces the pain associated with traditional acupuncture. This study assessed the effectiveness of integrating press needles alongside pharmacologic treatment in patients with mild-to-moderate COVID-19.

Liver stiffness in hepatocellular carcinoma and chronic hepatitis patients: Hepatitis B virus infection and transaminases should be considered.

Background: Liver condition is a crucial prognostic factor for patients with hepatocellular carcinoma (HCC), but a convenient and comprehensive method to assess liver condition is lacking. Liver stiffness (LS) measured by two-dimensional shear wave elastography may help in assessing liver fibrosis and liver condition. Chronic hepatitis B (CHB) is an important risk factor for HCC progression, but LS was found to be less reliable in assessing liver fibrosis following hepatitis viral eradication.

Effect of electroacupuncture on myocardial transient receptor potential channels in mice with myocardial hypertrophy.

Objectives: To observe the effect of electroacupuncture (EA) at "Neiguan"(PC6) on cardiac function, cardiac morphology and transient receptor potential channel (TRPC) protein expressions in myocardial tissue of mice with myocardial hypertrophy, so as to explore its mechanisms underlying improvement of myocardial hypertrophy.

Methods: Forty-five male C57BL/6 mice were randomly divided into control, model and EA groups (15 mice/group). The myocardial hypertrophy model was established by subcutaneous injection of isoproterenol hydrochloride (15 mg·kg·d) for 14 days.

The effectiveness of high-intensity laser therapy in individuals with neck pain: a systematic review and meta-analysis.

Objectives: The primary objective of this meta-analysis was to determine whether high-intensity laser therapy (HILT) was effective in improving pain intensity, cervical range of motion (ROM), functional activity, and quality of life (QOL) in individuals with neck pain.

Data Sources: PubMed, PEDro, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov were searched from inception to March 26, 2022.

2D Ni-organic frameworks decorated carbon nanotubes encapsulated Ni nanoparticles for robust CN and HO bonds cleavage.

In this work, we report a robust bifunctional electrocatalyst composed of 2D Ni- organic frameworks (Ni-MOF) and nitrogen doped carbon nanotubes encapsulated Ni nanoparticles (Ni-MOF@Ni-NCNT) for CN and HO bonds dissociation. Due to the presence of Ni-NCNT, adsorption of OH species is enhanced and CO binding strength is simultaneously weakened leading to a boosted urea oxidation reaction performance reflected by decrement in potential at 100 mA cm by 69 mV. The loosened binding strength with CO specie is highlighted by in-situ electrochemical impedance spectroscopy (EIS) test and DFT calculation.
