Metal Doping Activation of Anion-Mediated Electron Transfer in Catalytic Reactions.

Heteroatom-doping has emerged as a transformative approach to producing high-performance catalysts, yet the current trial-and-error approach to optimize these materials remains ineffective. To enable the rational design of more efficient catalysts, models grounded in a deeper understanding of catalytic mechanisms are essential. Existing models, such as -band center theory, fall short in explaining the role of dopants, particularly when these dopants do not directly interact with reactants.

Prognostic Value of Ki-67 in the Invasive Zone of Oral Squamous Cell Carcinoma.

Background: The molecular profile of cells within the tumor invasive zone, where tumor cells interact with surrounding non-tumor cells, plays a crucial role in defining tumor malignant characteristics, such as the pattern of invasion (POI). Therefore, evaluating the diagnostic value of the proliferation index molecule, Ki-67, in both tumor cells and adjacent non-tumor cells at the invasive zone with different POIs, holds significant clinical importance for oral squamous cell carcinoma (OSCC).

Methods: This retrospective study included 133 primary OSCC samples, and the spatial pattern of Ki-67 in the tumor invasive zone was analyzed by immunohistochemistry (IHC).

Mechanical and Energy Evolution Characteristics of Fractured Sandstone Materials: A True Triaxial Experimental Study.

To investigate the mechanical and energy evolution characteristics of fractured rock under true triaxial stresses, true triaxial strength compression experiments on fractured sandstone were conducted with varying crack lengths and widths. The results indicate that under true triaxial stresses, the peak stress of the rock exhibits a gradual decline with an increase in crack length and width. Meanwhile, crack initiation stress and crack damage stress of fractured sandstone also demonstrate a declining trend overall, and the influence of crack length on the characteristic stress (crack initiation stress and crack damage stress) of sandstone is more pronounced than that of crack width.

Design of an Ultra-Highly Stable Lithium-Sulfur Battery by Regulating the Redox Activity of Electrocatalyst and the Growth of Lithium Dendrite through Localized Electric Field.

Polysulfide shuttling and dendrite growth are two primary challenges that significantly limit the practical applications of lithium-sulfur batteries (LSBs). Herein, a three-in-one strategy for a separator based on a localized electrostatic field is demonstrated to simultaneously achieve shuttle inhibition of polysulfides, catalytic activation of the Li-S reaction, and dendrite-free plating of lithium ions. Specifically, an interlayer of polyacrylonitrile nanofiber (PNF) incorporating poled BaTiO (PBTO) particles and coating with a layer of MoS (PBTO@PNF-MoS) is developed on the PP separator.

To investigate the clinical application of fiberoptic endoscopic evaluation of swallowing (FEES) and recovery of swallowing function in patients with lesions involving both the oral and base of the tongue (OBOT). Patients diagnosed with OBOT lesions underwent assessments preoperatively and at 1 week, 1 month, and 1 year postoperatively. The swallowing function evaluation included the MD Anderson Dysphagia Inventory (MDADI), University of Washington Quality-of-Life Questionnaire, Performance Status Scale for Head and Neck Cancer, water swallow test, tongue motion measurement, and FEES (a simple dysphagia score, and penetration-aspiration scale).

Elucidating the Chemical Pre-Lithiation Mechanism of Hard Carbon Anodes for Ultra-high Stability Lithium-Ion Batteries.

The hard carbon (HC) anode materials demonstrate high capacity and excellent rate performance in lithium-ion batteries. However, HC anodes suffer from excessive loss of Li ions during the formation of the solid electrolyte interphase (SEI) film, leading to poor cycling stability, which hinders their large-scale applications. Herein, a facile pre-lithiation strategy is proposed to achieve multi-functional precompensation of carbon nanofibers (CNFs) anodes.

Construction of a nomogram for predicting HNSCC distant metastasis and identification of EIF5A as a hub gene.

Patients with distant metastasis of head and neck squamous cell carcinoma (HNSCC) often have a poor prognosis. However, early diagnosis of distant metastasis is challenging in clinical practice, and distant metastasis is often only detected in the late stages of tumor metastasis through imaging techniques. In this study, we utilized data from HNSCC patients collected from the TCGA database.

Experimental Study on the Response of Cracked Sandstone to the Intermediate Principal Stress Coupled with Pore Pressure.

Underground fractured rock masses are susceptible to failure under the combined influence of true triaxial stresses and pore pressure, posing severe threats to personnel and production safety of underground engineering. To investigate the influence of intermediate principal stress (σ) on the mechanical and water diffusion volume change (Δ) characteristics during the failure process of cracked rocks under stable pore pressure, this study conducted true triaxial strength experiments on cracked sandstone with stable pore pressure. The results demonstrated that with the increase of σ, crack initiation stress (σ), crack damage stress (σ) and the peak stress (σ) of cracked sandstone initially increase and then decrease.

A fault diagnosis method for wireless sensor network nodes based on a belief rule base with adaptive attribute weights.

Due to the harsh operating environment and ultralong operating hours of wireless sensor networks (WSNs), node failures are inevitable. Ensuring the reliability of the data collected by the WSN necessitates the utmost importance of diagnosing faults in nodes within the WSN. Typically, the initial step in the fault diagnosis of WSN nodes involves extracting numerical features from neighboring nodes.

IL-36 antagonism blunts the proliferation and migration of oral squamous cell carcinoma cells.

IL-36 is known to mediate inflammation and fibrosis. Nevertheless, IL-36 signalling axis has also been implicated in cancer, although understanding of exact contribution of IL-36 to cancer progression is very limited, partly due to existence of multiple IL-36 ligands with agonistic and antagonistic function. Here we explored the role of IL-36 in oral squamous cell carcinoma (OSCC).

Boosting Charge Transport and Catalytic Performance in MoS by Zn Intercalation Engineering for Lithium-Sulfur Batteries.

Transition metal dichalcogenides (TMDs) have been widely studied as catalysts for lithium-sulfur batteries due to their good catalytic properties. However, their poor electronic conductivity leads to slow sulfur reduction reactions. Herein, a simple Zn intercalation strategy was proposed to promote the phase transition from semiconducting 2H-phase to metallic 1T-phase of MoS.

Halofuginone inhibits tumor migration and invasion by affecting cancer-associated fibroblasts in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is the most common malignant tumor in the oral and maxillofacial regions, with a high rate of metastasis. Cancer-associated fibroblasts (CAFs) play critical roles in tumor growth, metastasis and invasion, making them attractive therapeutic targets for cancer treatment. As an old anti-coccidiosis drug for poultry, Halofuginone (HF) has also been reported to possess anti-fibrosis and anti-cancer activities in the recent decades.

We used ultrahigh-performance liquid chromatography Q Exactive mass spectrometry and multivariate statistical analyses to conduct a comprehensive analysis of serum metabolites in a population with normal control and SGTs.

Clinical application of indocyanine green fluorescence navigation technology to determine the safe margin of advanced oral squamous cell carcinoma.

Background: Advanced oral squamous cell carcinoma (OSCC) has large lesions and deep infiltration, and the control of safe surgical margins was difficult. If residual tumor remains after incomplete tumor resection, it can lead to local tumor recurrence or even distant metastasis. This study sought to investigate the clinical application of indocyanine green (ICG)-based near-infrared fluorescence (NIF) molecular imaging in the intraoperative detection of surgical margins of advanced OSCC.
