Astaxanthin Increases Tumor Suppressor Gene Expression and Affects Cellular Biological Behavior in Oral Dysplastic Keratinocytes by Regulating DNA Methylation.

Background: The inactivation of tumor suppressor genes (TSGs) caused by abnormal DNA methylation is confirmed to be widely present in oral potential malignant diseases (OPMDs). Carotenoids like lycopene and astaxanthin can regulate DNA methylation and exert anticancer effects. Therapeutic effect of astaxanthin in OPMDs and oral squamous cell carcinoma (OSCC) models is confirmed, but the relationship between the anti-cancer ability of astaxanthin and its DNA methylation regulation ability remains unclear.

The Occurrence Characteristics and Enrichment Patterns of Shale Oil in Different Lithofacies: A Case Study of the Fengcheng Formation in the Mahu Sag.

The supply of shale oil is of significant importance to the sustainability of energy resources. However, due to the diversity of shale lithofacies, the occurrence characteristics and enrichment patterns of free oil and adsorbed oil remain unclear. Based on this, taking the shale oil reservoir of the Fengcheng Formation in the Mahu Sag as the research object, a series of experiments were conducted, including X-ray diffraction analysis (XRD), total organic carbon (TOC) content analysis, high-pressure mercury injection (HPMI), and field emission scanning electron microscopy (FE-SEM).

[An in vitro experiment on the stability and irritant of hypochlorous acid in oral cavity].

Purpose: To study the stability of physicochemical properties and sterilizing effect about two commercially available hypochlorous acid (HClO) products under simulated clinical conditions, and to evaluate the compatibility of HClO on soft and hard tissues and cells in oral cavity.

Methods: Samples of HClO solution with different production processes were prepared, to detect the changes of physicochemical indexes of each sample over time under simulated clinical conditions (shielded from light at 20-25 ℃, open the cover for 5 minutes every day), including free available chlorine, oxidation-reduction potential and pH. Through suspension quantitative germicidal test, the antibiosis-concentration curve of HClO solution was made, so as to calibrate the change of antibacterial ability of disinfectant with the decrease of available chlorine content during storage.

Construction of Cyan Blue Fluorescence Probe based on Nitrogen-Doped Carbon Dots for Detecting Nitrite Ion in Ham Sausage.

Nitrite ion is one of the materials widely used in human life, and the accurate, sensitive and stable detection of nitrite ions is of great significance to people's healthy life. In this study, nitrogen-doped fluorescent carbon dots (N-CDs) for detecting nitrite salt solutions were prepared using citric acid monohydrate and Chrysoidin as precursors through a one-pot hydrothermal method. Under the condition of pH = 3, a noticeable quenching phenomenon occurred in the carbon dot solution with the increase in nitrite ion concentration.

Monolayer V_{2}MX_{4}: A New Family of Quantum Anomalous Hall Insulators.

We theoretically propose that the van der Waals layered ternary transition metal chalcogenide V_{2}MX_{4} (M=W, Mo; X=S, Se) is a new family of quantum anomalous Hall insulators with sizable bulk gap and Chern number C=-1. The large topological gap originates from the deep band inversion between spin-up bands contributed by d_{xz}, d_{yz} orbitals of V and spin-down band from d_{z^{2}} orbital of M at the Fermi level. Remarkably, the Curie temperature of monolayer V_{2}MX_{4} is predicted to be much higher than that of monolayer MnBi_{2}Te_{4}.

Nitrogen and Sulfur co-doped Carbon dots as an "on-off-on" Fluorescent Sensor for the Detection of Hg and Ampicillin.

Herein, a fluorescent "on-off-on" nanosensor based on N,S-CDs was developed for highly precise and sensitive recognition of Hg and ampicillin (AMP). Nitrogen and sulfur co-doped carbon dots with blue fluorescence were synthesized by one-pot hydrothermal method using ammonium citrate and DL-methionine as precursors. N,S-CDs exhibited a surface abundant in -OH, -COOH, and -NH groups, aiding in creating non-fluorescent ground state complexes when combined with Hg, leading to the suppression of N,S-CDs' fluorescence.

Ce-doping induces rapid electron transfer in a bimetallic phosphide heterostructure to achieve efficient hydrogen production.

Using electrochemical water splitting to generate hydrogen is considered a desirable approach, which is greatly impeded by the sluggish dissociation of HO and adsorption and desorption of H*. Effective hydrogen production can be achieved by speeding up the chemical process with a suitable electrocatalyst. In this work, we designed and synthesized a rare earth element cerium (Ce) regulated iron-nickel bimetallic phosphide Ce-NiFeP@NF (here NiFeP represents FeP/NiP) nanoarray with nanoflowers.

Our study aimed to analyze the prognostic factors influencing the survival of HVC-BCS patients with HCC and to develop a prognostic scoring system.

Methods: The clinical and follow-up data of 64 HVC-BCS patients with HCC who received invasive treatment at the First Affiliated Hospital of Zhengzhou University between January 2015 and December 2019 were retrospectively analyzed.

Selective degradation of organic micropollutants by activation of peroxymonosulfate by Se@NC: Role of Se doping and nonradical pathway mechanism.

In this study, Se@NC-x decorated with Se was successfully prepared via two-step calcination with zeolitic imidazole framework (ZIF) as a precursor. Mechanistic studies show that PMS would be adsorbed onto the surface of Se@NC-900 to form an active complex (Se@NC-900/PMS*), and the active Se@NC-900/PMS* could oxidize phenol by the rapid decomposition of PMS. Specifically, electrons are extracted by Se@NC-900/PMS* and then transferred to the surface of Se@NC-900, which can trigger the degradation of phenol.

Prognostic prediction and immune infiltration analysis based on ferroptosis and EMT state in hepatocellular carcinoma.

Background: Ferroptosis is one of the main mechanisms of sorafenib against hepatocellular carcinoma (HCC). Epithelial-mesenchymal transition (EMT) plays an important role in the heterogeneity, tumor metastasis, immunosuppressive microenvironment, and drug resistance of HCC. However, there are few studies looking into the relationship between ferroptosis and EMT and how they may affect the prognosis of HCC collectively.

However, how KIAA1429 functions in alternative splicing is not fully reported.

Highly efficient enrichment of intact phosphoproteins by a cadmium ion-based co-precipitation strategy.

Selective separation and enrichment of phosphoproteins are essential for understanding their important functions in almost all cellular processes. Here, taking advantage of the feature that cadmium ion (Cd ) has an overwhelming preference for phosphates, we developed a robust and simple Cd co-precipitation strategy for the selective isolation of intact phosphoproteins. After evaluating the feasibility of Cd in phosphoprotein precipitation, we compared the washing protocols for the removal of non-specific binding proteins and then used the best-performing protocol for the isolation of phosphoproteins from different complex samples.

Flat Chern Band from Twisted Bilayer MnBi_{2}Te_{4}.

We construct a continuum model for the moiré superlattice of twisted bilayer MnBi_{2}Te_{4}, and study the band structure of the bilayer in both ferromagnetic (FM) and antiferromagnetic (AFM) phases. We find the system exhibits highly tunable Chern bands with Chern number up to 3. We show that a twist angle of 1° turns the highest valence band into a flat band with Chern number ±1 that is isolated from all other bands in both FM and AFM phases.

A portable immune-thermometer assay based on the photothermal effect of graphene oxides for the rapid detection of Salmonella typhimurium.

Previously reported photothermal strip test methods generally used a membrane as the antibody carrier and a thermal imaging camera or sensor as detector. To further simplify the detection device, a modified mercury head of the glass thermometer can act as the antibody carrier. Meanwhile, the temperature variation signal (ΔT) generated by the photothermal effect of labeled nanomaterials can be detected by the thermometer directly.

Severe hyponatraemia with neurological manifestations in patients treated with terlipressin: Two case reports.

What Is Known And Objective: Terlipressin has been shown to be effective in controlling variceal bleeding and decreasing associated mortality. Terlipressin is a synthetic analogue of vasopressin and is safer than arginine vasopressin; it induces selective vasoconstriction by stimulating the vasopressin V1 receptors that are predominantly located in the splanchnic tissues. However, severe hyponatraemia may occur during terlipressin treatment, resulting in neurological manifestations.
