Transition-metal carbides have been advocated as the promising alternatives to noble-metal platinum-based catalysts in electrocatalytic hydrogen evolution reaction over half a century. However, the effectiveness of transition-metal carbides catalyzing hydrogen evolution in high-pH electrolyte is severely compromised due to the lowered proton activity and intractable alkaline-leaching issue of transition-metal centers. Herein, on the basis of validation of molybdenum-carbide model-catalyst system by taking advantage of surface science techniques, MoC micro-size spheres terminated by Al doped MoO layer exhibit a notable performance of alkaline hydrogen evolution with a near-zero onset-potential, a low overpotential (40 mV) at a typical current density of 10 mA/cm, and a small Tafel slope (45 mV/dec), as well as a long-term stability for continuous hydrogen production over 200 h.

In this editorial, we have taken an in-depth look at the article published by Wan . The study showed that preconditioning mesenchymal stem cells (MSCs) protected them against programmed cell death, and increased their survival rate and therapeutic potential. Autophagy, a type of programmed cell death, is a major intracellular degradation and recycling pathway that is crucial for maintaining cellular homeostasis, self-renewal, and pluripotency.

Background: Parkinson's disease (PD) is a progressive neurodegenerative disease associated with functional and structural alterations beyond the nigrostriatal dopamine projection. However, the structural-functional (SC-FC) coupling changes in combination with subcortical regions at the network level are rarely investigated in PD.

Methods: SC-FC coupling networks were systematically constructed using the structural connectivity obtained by diffusion tensor imaging and the functional connectivity obtained by resting-state functional magnetic resonance imaging in 53 PD and 72 age- and sex-matched healthy controls (HCs).

Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are key downstream effectors of the Hippo pathway that regulate organ size, tissue homeostasis, and cancer development. YAP/TAZ play crucial regulatory roles in organ growth, cell proliferation, cell renewal, and regeneration. Mechanistically, YAP/TAZ influence the occurrence and progression of liver regeneration (LR) through various signaling pathways, including Notch, Wnt/β-catenin, TGF-β/Smad.

Fibroids are the most common benign tumors of the female reproductive system. Most patients with fibroids are asymptomatic, but the presence of fibroids can still cause some abnormal clinical symptoms, such as increased menstrual volume, abnormal uterine bleeding, pelvic pain, urinary tract and gastrointestinal tract compression symptoms, etc. The impact of fibroids on pregnancy is worth discussing.

Immune checkpoint blockade (ICB) therapy has significantly benefited patients with several types of solid tumors and some lymphomas. However, many of the treated patients do not have a durable clinical response. It has been demonstrated that rescuing exhausted CD8 T cells is required for ICB-mediated antitumor effects.

Glycosaminoglycans (GAG) are bioactive polysaccharide rich in -SO- and -COO- groups, also known as acidic mucopolysaccharides. In this study, the feasibility of three structurally distinct forms of chondroitin sulfate (CS-A, CS-C, and CS-D) from the GAG family was explored as a potential strategy to enhance industrial α-amylase activity. All three CSs were found to increase α-amylase activity to varying degrees, with CS-D showing the most significant increase, exceeding 78 %.

  • - Aberrant RNA modifications, particularly 5-methylcytosine (m5C), contribute to cancer progression, with the m5C methyltransferase NSUN5 being notably upregulated in esophageal cancer (ESCA) and showing potential for diagnostic use.
  • - Silencing NSUN5 hampers ESCA cell growth and stalls the cell cycle, while increasing NSUN5 levels promotes tumor growth; experiments in mice further demonstrate that reduced NSUN5 leads to decreased tumor development.
  • - NSUN5 enhances the expression of the oncogenic protein METTL1 by binding to its transcript, emphasizing the importance of the NSUN5/METTL1 pathway in ESCA and suggesting it as a possible target for cancer

Calnexin serves as a lectin chaperone located on the endoplasmic reticulum membrane and functions in glycoprotein folding and synthesis quality control, as well as in Ca storage. Calnexin is extensively documented to participate in host immunity in the endoplasmic reticulum. However, the functions and fundamental mechanisms of calnexin in the invertebrate innate defence remain largely unknown.

The multi-element synergism in high-entropy materials (HEMs) provides great opportunities as multi-functional catalysts or for the promotion of tandem reactions. Herein, a strategy that utilizes a high entropy precursor is proposed to realize the formation of a unique high entropy metallic-high entropy non-metallic community (HEM-HENMC). Aminotriazole acts as a "bonding agent" for the high entropy precursor, and not only binds the five metals Cr, Mn, Fe, Co and Ni together, but also introduces nitrogen and carbon .

Dysregulation of long non-coding RNAs (lncRNAs) and interferon signaling contributes to tumorigenesis and progression; however, their crosstalk in tumor biology remains poorly understood. Here, we showed that TSPEAR-AS2, an lncRNA mediated by METTL1, activates the interferon signaling pathway in esophageal cancer (ESCA). Clinically, we conducted a pan-cancer investigation and identified TSPEAR-AS2 as a novel ESCA-related lncRNA that predicts a worse patient prognosis.

Our objective was to evaluate the ramifications of the 2019 coronavirus disease (COVID-19) pandemic on the microbial profile and antimicrobial resistance patterns of bacteria isolated from cerebrospinal fluid (CSF) specimens of patients with bacterial meningitis. We conducted a retrospective analysis of laboratory results and clinical records about positive CSF cultures reported by the SPARSS network from 2017 to 2023. The study covered three distinct periods: January 2017 to December 2019 (before the COVID-19 pandemic), January 2020 to December 2022 (during the COVID-19 pandemic), and January 2023 to December 2023 (after the COVID-19 pandemic), with a total of 5793 CSF isolates collected.

Rechargeable solid-state sodium metal batteries (SSMBs) experience growing attention owing to the increased energy density (vs Na-ion batteries) and cost-effective materials. Inorganic sulfide-based Na-ion conductors also possess significant potential as promising solid electrolytes (SEs) in SSMBs. Nevertheless, due to the highly reactive Na metal, poor interface compatibility is the biggest obstacle for inorganic sulfide solid electrolytes such as NaSbS to achieve high performance in SSMBs.
