In Situ Fabrication of Mn-Doped NiMoO Rod-like Arrays as High Performance OER Electrocatalyst.

The slow kinetics of the oxygen evolution reaction (OER) is one of the significant reasons limiting the development of electrochemical hydrolysis. Doping metallic elements and building layered structures have been considered effective strategies for improving the electrocatalytic performance of the materials. Herein, we report flower-like nanosheet arrays of Mn-doped-NiMoO/NF (where NF is nickel foam) on nickel foam by a two-step hydrothermal method and a one-step calcination method.

Development of Automatic Portable Pathology Scanner and Its Evaluation for Clinical Practice.

Digital pathological scanners transform traditional glass slides into whole slide images (WSIs), which significantly improve the efficiency of pathological diagnosis and promote the development of digital pathology. However, the huge economic burden limits the spread and application of general WSI scanners in relatively remote and backward regions. In this paper, we develop an automatic portable cytopathology scanner based on mobile internet, Landing-Smart, to avert the above problems.

Electrochemical response of solidification Cu contaminated soil influenced by red mud/fly ash ratio.

The main purpose of this work was to study a new method for evaluating the solidification of contaminated soil based on electrochemical impedance spectroscopy (EIS). To explore how the EIS parameters were affected by the pore structure and mesostructure of the cured system, the physical and mechanical properties, leaching toxicity, microstructure, and EIS of the stabilized contaminated soil were tested after 7, 28, 60, and 90 days of curing. Based on the EIS results, a physical and equivalent circuit model of the stabilized contaminated soil's impedance response was established to reveal the mechanism of binder-heavy metal ion-soil interaction.

Accurate classification of white blood cells by coupling pre-trained ResNet and DenseNet with SCAM mechanism.

Background: Via counting the different kinds of white blood cells (WBCs), a good quantitative description of a person's health status is obtained, thus forming the critical aspects for the early treatment of several diseases. Thereby, correct classification of WBCs is crucial. Unfortunately, the manual microscopic evaluation is complicated, time-consuming, and subjective, so its statistical reliability becomes limited.

The interplay between selective etching induced cation defects and active oxygen species for volatile organic compounds degradation.

Surface electronic structure of transition metal oxides plays a vital role in determining the catalytic performance. Herein, we present a selective etching strategy to tune the surface cation defect of the CuWO (CW) catalyst for improving the catalytic activity of volatile organic compounds (VOCs). HRTEM, SEM-EDS, EPR, and XPS show that the chelation of metal ions in acetic acid and ammonium hydroxide can help to remove a small number of surface cations in CW to form suitable W defects.

fabrication of porous biochar reinforced WO nanocomposite for methylene blue photodegradation.

In this paper, a novel cow dung based activated carbon (CDAC) was successfully modified by WO nanowires as a photocatalyst using KOH activation and a hydrothermal method. The activity of photocatalytic degradation of methylene blue (MB) under full-spectrum light illumination shows great improvement, and the degradation rate of MB could reach 98% after 240 min (67% for WO), with a final degradation rate of 98%. The porous structure with specific surface area of CDAC (∼479 m g) increases the adsorption of WO reactants and also raises the concentration of reactants in the photocatalytic region.

Chemically activated core-shell structured IF-WS@C nanoparticles enhance sugarcane-based carbon/epoxy nanocomposites.

Ternary composites have demonstrated better capability than binary composites in enhancing the mechanical properties of the modified epoxy resins and are, therefore, currently under intensive investigation. Herein, we report a novel ternary nanocomposite prepared by filling a binary BPF (bisphenol F epoxy resin)/SCPs (sugarcane-based carbon powders) matrix with C-coated inorganic fullerene-like tungsten disulfide (IF-WS@C) nanoparticles, and the analysis of its interface synergetic effect using XPS/FTIR. This activated nano-carbon core-shell structure filler is considered an ideal nanofiller and shows the excellent mechanical performance of the ternary composites.

The artificial intelligence-assisted cytology diagnostic system in large-scale cervical cancer screening: A population-based cohort study of 0.7 million women.

Background: Adequate cytology is limited by insufficient cytologists in a large-scale cervical cancer screening. We aimed to develop an artificial intelligence (AI)-assisted cytology system in cervical cancer screening program.

Methods: We conducted a perspective cohort study within a population-based cervical cancer screening program for 0.

N-Docosahexaenoylethanolamide promotes development of hippocampal neurons.

DHA (docosahexaenoic acid, C22:6,n-3) has been shown to promote neurite growth and synaptogenesis in embryonic hippocampal neurons, supporting the importance of DHA known for hippocampus-related learning and memory function. In the present study, we demonstrate that DHA metabolism to DEA (N-docosahexaenoylethanolamide) is a significant mechanism for hippocampal neuronal development, contributing to synaptic function. We found that a fatty acid amide hydrolase inhibitor URB597 potentiates DHA-induced neurite growth, synaptogenesis and synaptic protein expression.

Docosahexaenoic acid promotes hippocampal neuronal development and synaptic function.

Docosahexaenoic acid (DHA, 22:6n-3), the major polyunsaturated fatty acid accumulated in the brain during development, has been implicated in learning and memory, but underlying cellular mechanisms are not clearly understood. Here, we demonstrate that DHA significantly affects hippocampal neuronal development and synaptic function in developing hippocampi. In embryonic neuronal cultures, DHA supplementation uniquely promoted neurite growth, synapsin puncta formation and synaptic protein expression, particularly synapsins and glutamate receptors.

Chronic daily administration of ethyl docosahexaenoate protects against gerbil brain ischemic damage through reduction of arachidonic acid liberation and accumulation.

Recently, we reported that dietary ethyl docosahexaenoate (Et-DHA) intake decreases the level of membrane arachidonic acid (AA), which reduces the generation of AA metabolites in ischemic gerbil brain. As an extended study, we further investigated the influence of the chronic administration of Et-DHA on free AA levels after ischemia. In addition, Na,K-ATPase activity, cation content, cerebral edema and brain damage were also evaluated.

New lignan glycosides from Cupressus duclouxian (Cupessaceae).

From the branches and leaves of Cupressus duclouxiana two new lignan glycosides named cupressoside A (1) and cupressoside B (2), together with matairesinoside (3), dihydrodehydrodiconiferyl alcohol (4), dihydrodehydrodiconiferyl alcohol-9-O-alpha-L-rhamnopyranoside (5), dihydrodehydrodiconiferyl alcohol-4-O-alpha-L-rhamnopyranoside (6), ( - )-isolariciresinol (7) and ( - )-isolariciresinol-9-O-beta-D-xylopyranoside (8), were isolated. The structures of these compounds were determined on the basis of their HR-FAB-MS, IR, UV, 1H and 13C NMR (DEPT), and 2D NMR (HMQC, HMBC, COSY, NOESY) spectral data.

Chronic administration of ethyl docosahexaenoate decreases mortality and cerebral edema in ischemic gerbils.

Dietary docosahexaenoic acid (DHA) intake can decrease the level of membrane arachidonic acid (AA), which is liberated during cerebral ischemia and implicated in the pathogenesis of brain damage. Therefore, in the present study, we investigated the effects of chronic ethyl docosahexaenoate (E-DHA) administration on mortality and cerebral edema induced by transient forebrain ischemia in gerbils. Male Mongolian gerbils were orally pretreated with either E-DHA (100, 150 mg/kg) or vehicle, once a day, for 4 weeks and were subjected to transient forebrain ischemia by bilateral common carotid occlusion for 30 min.

Effects of docosahexaenoic acid on the survival and neurite outgrowth of rat cortical neurons in primary cultures.

Effects of docosahexaenoic acid (DHA) on survival and neurite outgrowth were investigated in primary cultures of rat cortical neurons. Cell cultures were prepared from cortex on embryonic day 18 (E-18) for treatment with a series of DHA concentrations (12.5, 25, 50, 75, 100 and 200 microM).

Chronic administration of ethyl docosahexaenoate reduces gerbil brain eicosanoid productions following ischemia and reperfusion.

Arachidonic acid (AA) and its vasoactive metabolites have been implicated in the pathogenesis of brain damage induced by cerebral ischemia. The membrane AA concentrations can be reduced by changes in dietary fatty acid intake. The purpose of the present study was to investigate the effects of chronic ethyl docosahexaenoate (E-DHA) administration on the generation of eicosanoids of AA metabolism during the period of reperfusion after ischemia in gerbils.

Protective effect of chronic ethyl docosahexaenoate administration on brain injury in ischemic gerbils.

There is evidence that the excessive generation of reactive oxygen free radicals contributes to the brain injury associated with cerebral ischemia. In the present study, the protective effect of chronic administration of ethyl docosahexaenoate (E-DHA) against oxidative brain injury was evaluated in the gerbil model of transient cerebral ischemia. Weanling male gerbils were orally pretreated with either E-DHA (200 mg/kg) or vehicle, once a day, for 10 weeks and subjected to bilateral occlusion of common carotid arteries for 10 min.
