High-purity hydrogen produced by water electrolysis has become a sustainable energy carrier. Due to the corrosive environments and strong oxidizing working conditions, the main challenge faced by acidic water oxidation is the decrease in the activity and stability of anodic electrocatalysts. To address this issue, efficient strategies have been developed to design electrocatalysts toward acidic OER with excellent intrinsic performance.

To explore the effects of infiltration resin, casein phosphate polypeptide-amorphous calcium phosphate (CPP-ACP) and fluoride on microhardness and micromorphology of irradiated enamel. Sixty human permanent teeth were mesiodistally sectioned, yielding 120 enamel samples, which randomly divided into 8 groups: G1: blank control; G2: irradiation control; G3: irradiation+fluoride; G4: irradiation+CPP-ACP; G5: irradiation+CPP-ACP+fluoride; G6: irradiation+infiltration resin; G7: irradiation+infiltration resin+fluoride; G8: irradiation+infiltration resin+CPP-ACP. A progressive improvement was observed on the superficial morphology of enamel treated with different anti-caries procedures.

Background: To compare different anti-caries agents on microhardness and micromorphology of irradiated permanent dentin in vitro, and try to find the most effective agent to prevent radiation-dentin-destruction.

Methods: A total of 120 dentin samples were prepared from 60 human teeth and randomly divided into 8 groups (n = 15), [ (1)] blank control [2]; irradiation control [3]; irradiation+ fluoride [4]; irradiation+ casein phosphate polypeptide-amorphous calcium phosphate (CPP-ACP) [5]; irradiation+ CPP-ACP+ fluoride [6]; irradiation+ infiltration resin [7]; irradiation+ infiltration resin+ fluoride [8]; irradiation+ infiltration resin+ CPP-ACP. Seven samples of each groups were chosen randomly for microhardness test and eight for scanning electron microscope observation.

In recent years, with the development of gene editing technology, the site-specific genome can be modified. The curability of genetic disease may be achieved by the use of gene editing techniques. As the simplicity, high specificity and economical efficiency, much attention has been paid to the CRISPR/Cas9 system, which was been widely used in research of molecular biology and other fields of life science.

Pyroptosis is a novel type of programmed cell death, which is closely related with the pathogenesis of myelodysplastic syndromes (MDS). The recent studies showed that all of S100A9/TLR4, S100A9/CD33 and Nox/ROS signaling pathways can activate oxygen-sensitivity NLRP3 inflammasome and then induce the pyroptosis of hematopoeitic stem cells (HSC) / hematopeitic pregenitor cells (HPC), resulting in ineffective hematopoiesis in patients with MDS. Further studies on the role and molecular mechanism of pyroptosis in the pathogenesis of MDS will provide the potential opportunity for the diagnosis and treatment of MDS.

Intratumor heterogeneity of tumor clones and an immunosuppressive microenvironment in cancer ecosystems contribute to inherent difficulties for tumor treatment. Recently, chimeric antigen receptor (CAR) T-cell therapy has been successfully applied in the treatment of B-cell malignancies, underscoring its great potential in antitumor therapy. However, functional challenges of CAR-T cell therapy, especially in solid tumors, remain.

The diagnostic, monitoring and therapeutic options for cancers currently remain limited. These limitations represent a large threat to human health. Adaptive immunity, which is dependent on diverse repertoires of B cell receptors (BCRs) and T cell receptors (TCRs), plays a critical role in the anti-tumor immune response.

Vine tea with strong antioxidant activity is commonly consumed as healthy tea/beverage. However, detailed information about its antioxidants is incomplete. Here, off-line hyphenation of heart-cutting high-speed countercurrent chromatography (HSCCC) with high performance liquid chromatography-diode array detector-quadrupole time-of-flight tandem mass spectrometry (HPLC-DAD-QTOF-MS/MS) were described for systematic profiling antioxidants in vine tea.

A significant proportion of hematological malignancies remain limited in treatment options. Immune system modulation serves as a promising therapeutic approach to eliminate malignant cells. Cytotoxic T lymphocytes (CTLs) play a central role in antitumor immunity; unfortunately, nonspecific approaches for targeted recognition of tumor cells by CTLs to mediate tumor immune evasion in hematological malignancies imply multiple mechanisms, which may or may not be clinically relevant.

Aggressive natural killer cell leukemia (ANKL) is a fatal hematological neoplasm characterized by a fulminating clinical course and extremely high mortality. Current diagnosis of this disease is not effective during the early stages and it is easily misdiagnosed as other NK cell disorders. We retrospectively analyzed the clinical characteristics and flow cytometric immunophenotype of 47 patients with ANKL.

The β-site amyloid precursor protein cleaving enzyme 1 (BACE1) initiates the generation of β-amyloid (Aβ) peptides which play a critical early role in the pathogenesis of Alzheimer's disease (AD), and thus it is a prime target for lowering the Aβ levels to treat AD. In the present work, a dataset of 128 promising hydroxyethylamine (HEA) derivatives as newly synthesized BACE1 inhibitors was selected to perform simulations by using 3D-QSAR, molecular docking and molecular dynamics (MD) approaches, to explore the binding mode and structural determinants required for high inhibitory potency. The resultant optimal comparative molecular similarity indices analysis (CoMSIA) model displays strong predictability (Q(2) = 0.

Diagnosis of acute promyelocytic leukemia (APL) has been accelerated by multiparameter flow cytometry (MFC). However, diagnostic interpretation of MFC readouts for APL depends on individual experience and knowledge, which inevitably increases the risk of arbitrariness. We appraised the feasibility of using stepwise discriminant function analysis (SDFA) based on MFC to optimize the minimal variables needed to distinguish APL from other acute myeloid leukemia (AML) without complicated data interpretation.
