Deciphering the Role of Lattice Selenium in Electrocatalytic Self-Reconstruction for Boosting Alkaline Hydrogen Evolution.

Cathode reconstruction is equally crucial for water electrolysis, yet it has received less attention than anode. Lattice selenium (Se) doping is an effective strategy to improve hydrogen evolution reaction (HER) of metal-based electrocatalysts in cathodes, but many fundamental questions concerning the actual role of Se on the active species as well as catalytic kinetics remain to be clarified, especially in those electrocatalytic self-reconstruction systems. Here, we showcase the accelerated two-stage structural evolution of Se-doped cobalt phosphide (Se-CoP) during alkaline HER by operando X-ray absorption spectroscopy and powder X-ray diffraction, combined with high-resolution transmission electron microscopy (HRTEM) analysis.

The influence of left-behind experiences on depression in single-parent adolescents: the mediating role of family satisfaction and the moderating effects of exercise frequency.

With the rise of rural-to-urban labor migration, the number of left-behind children in single-parent families has increased, raising concerns about their mental health. This study examines the impact of left-behind experiences on depression in single-parent left-behind adolescents, particularly focusing on the mediating role of family satisfaction and the moderating effects of exercise frequency and separation age. Using cross-sectional data from the China Psychological Health Guardian Project (CPHG), which includes 23,523 single-parent left-behind adolescents aged 12-18, we collected data on left-behind experiences, depressive symptoms, family satisfaction, exercise frequency, and separation age through questionnaires.

Risk of intracerebral haemorrhage with tenecteplase versus alteplase in acute ischaemic stroke: a meta-analysis.

Background: Tenecteplase (TNK) has been widely used in thrombolytic therapy for acute ischaemic stroke (AIS), but TNK-related intracranial haemorrhage(ICH) remains a severe complication. However, few data are available to guide the management of tenecteplase-related intracranial haemorrhage. The objective of this study was to evaluate the risk of intracranial haemorrhage associated with tenecteplase compared with alteplase in patients with acute ischaemic stroke.

5-Aminopyrazole Dimerization: Cu-Promoted Switchable Synthesis of Pyrazole-Fused Pyridazines and Pyrazines via Direct Coupling of C-H/N-H, C-H/C-H, and N-H/N-H Bonds.

A Cu-promoted highly chemoselective dimerization of 5-aminopyrazoles to produce pyrazole-fused pyridazines and pyrazines is reported. The protocol generates switchable products via the direct coupling of C-H/N-H, C-H/C-H and N-H/N-H bonds, with the merits of broad substrate scope and high functional group compatibility. Gram-scale experiments demonstrated the potential applications of this reaction.

Comparative Transcriptomics Uncovers Upstream Factors Regulating Expression and Affecting Linolenic Acid Biosynthesis in Yellow-Seeded Rapeseed ( L.).

α-Linolenic acid (ALA) is an important nutrient component in rapeseed oil, and rapeseed breeders want to either restrain or enhance the function of fatty acid desaturases (FADs) in the ALA biosynthesis pathway. To determine the reason for the upregulation of rapeseed genes in two high-ALA accessions, R8Q10 and YH25005, we compared their transcriptome profiles in the seed at 24 days after pollination (DAP) with those of two low-ALA lines, A28 and SW. The expression levels of twenty-eight important genes in the seed samples at 20, 27, and 34 DAP were also investigated using an RT-qPCR.

Redox mediator chlorophyll accelerates low-temperature biological denitrification with responses of extracellular polymers and changes in microbial community composition.

Low temperatures limit the denitrification wastewater in activated sludge systems, but this can be mitigated by addition of redox mediators (RMs). Here, the effects of chlorophyll (Chl), 1,2-naphthoquinone-4-sulfonic acid (NQS), humic acid (HA), and riboflavin (RF), each tested at three concentrations, were compared for denitrification performance at low temperature, by monitoring the produced extracellular polymeric substances (EPS), and characterizing microbial communities and their metabolic potential. Chl increased the denitrification rate most, namely 4.

An investigation into the correlation between visual performance in simulated complex environments and academic attainment among primary school students.

Traditional vision screenings in schools are limited to simple visual tasks, yet students in their daily learning face more complex visual environments. Binocular rivalry tasks can partially simulate the visual challenges of real visual environments and activate advanced visual processing mechanisms that simple visual tasks cannot. Therefore, by superimposing binocular rivalry-state tasks onto simple visual tasks, we have developed an innovative vision screening program to rapidly and extensively assess students' visual performance in complex environments.

Clinical Implementation of Dual-Energy CT Technical for Hepatobiliary Imaging.

Dual-energy computed tomography (DECT) applies two energy spectra distributions to collect raw data based on traditional CT imaging. The application of hepatobiliary imaging, has the advantages of optimizing the scanning scheme, improving the imaging quality, highlighting the disease characterization, and increasing the detection rate of lesions. In order to summarize the clinical application value of DECT in hepatobiliary diseases, we searched the technical principles of DECT and its existing studies, case reports, and clinical guidelines in hepatobiliary imaging from 2010 to 2023 (especially in the past 5 years) through PubMed and CNKI, focusing on the clinical application of DECT in hepatobiliary diseases, including liver tumors, diffuse liver lesions, and biliary system lesions.

Optimizing the Spatial Density of Single Co Sites Molecular Spacing for Facilitating Sustainable Water Oxidation.

Advances in single-atom (-site) catalysts (SACs) provide a new solution of atomic economy and accuracy for designing efficient electrocatalysts. In addition to a precise local coordination environment, controllable spatial active structure and tolerance under harsh operating conditions remain great challenges in the development of SACs. Here, we show a series of molecule-spaced SACs (msSACs) using different acid anhydrides to regulate the spatial density of discrete metal phthalocyanines with single Co sites, which significantly improve the effective active-site numbers and mass transfer, enabling one of the msSACs connected by pyromellitic dianhydride to exhibit an outstanding mass activity of (1.

Magnetite nanoparticle coating chemistry regulates root uptake pathways and iron chlorosis in plants.

Understanding the fundamental interaction of nanoparticles at plant interfaces is critical for reaching field-scale applications of nanotechnology-enabled plant agriculture, as the processes between nanoparticles and root interfaces such as root compartments and root exudates remain largely unclear. Here, using iron deficiency-induced plant chlorosis as an indicator phenotype, we evaluated the iron transport capacity of FeO nanoparticles coated with citrate (CA) or polyacrylic acid (PAA) in the plant rhizosphere. Both nanoparticles can be used as a regulator of plant hormones to promote root elongation, but they regulate iron deficiency in plant in distinctive ways.
