The rapid, sensitive and reliable detection of oral cancer overexpressed 1 (ORAOV 1) is crucial for the early, non-invasive diagnosis of oral squamous cell carcinoma (OSCC). Herein, we are the first to construct an ultrasensitive electrochemical (EC) biosensor based on an entropy-driven "two-way signal output" (TWSO) cyclic circuit for salivary ORAOV 1 detection. This innovative TWSO cyclic circuit can skillfully convert by-products into desired signal-generating units, not only reducing the excessive accumulation of by-products but also improving the utilization efficiency of output chains, thereby achieving rapid reaction kinetics and high signal outputs.

Article Synopsis
  • Intervertebral disc degeneration (IVDD) is a major cause of low back pain, and while Sirt1 agonists show promise in protecting intervertebral discs, the exact mechanisms involved are not fully understood.
  • The study utilized various models to investigate the role of Sirt1 in disc cell inflammation and homeostasis, revealing that Sirt1 overexpression can inhibit inflammation and matrix degradation in degenerating discs.
  • Findings suggest that Sirt1 regulates inflammation by negatively impacting Lipocalin 2, signaling a potential pathway for developing treatments aimed at preventing IVDD progression.

Improving the photogenerated carrier separation efficiency of individual semiconductor materials has always been a key challenge in photocatalysis. In this study, we synthesized a novel photocatalytic material, N-CQDs/UBWO, in situ by combining nitrogen-doped carbon quantum dots (N-CQDs) derived from discarded corn stover with ultrathin BiWO nanosheets (UBWO). Detailed characterization indicates that the random distribution of N-CQDs on the UBWO surface increases the specific surface area of UBWO, which is beneficial for the adsorption and degradation of oxytetracycline (OTC).

The first Ni-catalyzed asymmetric decarboxylative strategy for the construction of carbocycles with contiguous quaternary all-carbon stereocenters is reported. The key to the success of these reactions is the utilization of rationally designed allenylic methylene cyclic carbonates as substrates with Ni catalysis. The floppy allenylic group exerts unique electronic properties on the carbonate, which allows further asymmetric nucleophilic annulations with alkenes.

Lithium-sulfur (Li-S) batteries represent a promising next-generation energy storage solution, yet their performance is hindered by the insulating nature of sulfur and the detrimental shuttle effect. This study presents the in-situ synthesis of metal-phase 1T-VS as a modified separator material on a two-dimensional Mxene substrate VC (VSC). The synergistic effect of strong adsorption by VC and highly conductive catalysis provided by 1T-VS significantly enhances the transport of ions and electrons between lithium polysulfide and the interface.

Electrochemical imaging enables an in-depth analysis of the interface heterogeneity and reaction kinetics of single entities. However, electrode passivation during electrochemical reactions decreases the active sites and harms the long-term stability. Here, we introduce a method using laser-induced photothermal effects to restore the electrochemical activity, which is particularly displayed as enhanced micrometric patterns in electrochemiluminescence (ECL) microscopy.

Mass spectrometry (MS)-based single-cell proteomics, while highly challenging, offers unique potential for a wide range of applications to interrogate cellular heterogeneity, trajectories, and phenotypes at a functional level. We report here the development of the spectral library-based multiplex segmented selected ion monitoring (SLB-msSIM) method, a conceptually unique approach with significantly enhanced sensitivity and robustness for single-cell analysis. The single-cell MS data is acquired by msSIM technique, which sequentially applies multiple isolation cycles with the quadrupole using a wide isolation window in each cycle to accumulate and store precursor ions in the C-trap for a single scan in the Orbitrap.

Introduction: In recent years, "lying flat" has emerged as a significant term in contemporary discourse, referring to the phenomenon where modern young people choose passive resistance due to a lack of motivation when facing various situations. These trends have the potential to diminish the future learning enthusiasm and holistic development of vocational high school students, thus impacting their competitiveness in the future job market.

Methods: This study employs a motivational model for vocational high school students based on self-efficacy theory and person-environment fit theory to explore whether the competitive atmosphere moderates the impact of self-efficacy and competitive attitudes on task motivation.

Objective: Distraction osteogenesis is a primary treatment for severe mandibular hypoplasia. Achieving the ideal mandible movement direction through precise distraction vector control is still a challenge in this surgery. Therefore, the aim of this study was to apply Optical See-Through (OST) Augmented Reality (AR) technology for intraoperative navigation during mandibular distractor installation and analyze the feasibility to evaluate the effectiveness of AR in a phantom experiment.

Background: Structural variations (SVs) are widespread across genome and have a great impact on evolution, disease, and phenotypic diversity. Despite the development of numerous bioinformatic tools, commonly referred to as SV callers, tailored for detecting SVs using whole genome sequence (WGS) data and employing diverse algorithms, their performance necessitates rigorous evaluation with real data and validated SVs. Moreover, a considerable proportion of these tools have been primarily designed and optimized using human genome data.

Efficient drug delivery across the blood-brain barrier is imperative for treating glioblastoma (GBM). This study utilized the GBM cell membrane to construct a biomimetic targeted nanosystem (GMNPs@AMD/RAPA) that hierarchically releases the CXCR4 antagonist AMD3100 and the mTOR pathway inhibitor rapamycin (RAPA) for reprogramming the tumor immune microenvironment and suppressing the progression of GBM. By initially inhibiting the CXCL12/CXCR4 axis, the tumor microenvironment (TME) was reprogrammed to enhance the infiltration of cytotoxic T lymphocytes (CTLs) into the TME while suppressing tumor cell survival, proliferation, and angiogenesis.

Renal transporters play critical roles in predicting potential drug-drug interactions. However, current models often fail to adequately express these transporters, particularly solute carrier proteins, including organic anion transporters (OAT1/3), and organic cation transporter 2 (OCT2). Here, we developed a hiPSC-derived kidney organoids-based proximal tubule-on-chip (OPTC) model that emulates renal physiology to assess transporter function.
