Fe/Co/Ni modified TiCT nanosheets accelerate alkaline hydrogen evolution reaction.

The novel two-dimensional MXene material TiCT boasts advantages such as large specific surface area, good electrical conductivity, and high stability, making it suitable for the field of electrocatalysis. However, TiCT exhibits unacceptably slow kinetics during the electrocatalytic hydrogen evolution reaction (HER). Electron-metal-support interaction is an effective method for regulating the electronic state of active sites and enhancing HER performance.

Multifunctional Meta-Devices for Full-Polarization Rotation and Focusing in the Near-Infrared.

The creation of multi-channel focused beams with arbitrary polarization states and their corresponding optical torques finds effective applications in the field of optical manipulation at the micro-nanoscale. The existing metasurface-based technologies for polarization rotation have made some progress, but they have been limited to single functions and have not yet achieved the generation of full polarization. In this work, we propose a multi-channel and spatial-multiplexing interference strategy for the generation of multi-channel focusing beams with arbitrary polarization rotation based on all-dielectric birefringent metasurfaces via simultaneously regulating the propagation phase and the geometric phase and independently controlling the wavefronts at different circular polarizations.

We conducted an inductive thematic analysis of four domains (physician perspective, patient perspective, chaperone perspective, and chaperone documentation).

Significant effect of posterior line treatment of HER2 positive advanced gastric cancer: A case report.

At present, there are few options for third line and above treatment of advanced gastric cancer and the single drug effect is poor. HER2 positive gastric cancer is an important subtype of gastric cancer and has certain immune characteristics. The combination of HER2 inhibitor and PD-1 inhibitor has a synergistic effect, and anti-tumor drugs targeting HER2 can play an anti-angiogenesis role by downregulating VEGF.

Construction of an immune-related gene signature for overall survival prediction and immune infiltration in gastric cancer.

Background: Treatment options for patients with gastric cancer (GC) continue to improve, but the overall prognosis is poor. The use of PD-1 inhibitors has also brought benefits to patients with advanced GC and has gradually become the new standard treatment option at present, and there is an urgent need to identify valuable biomarkers to classify patients with different characteristics into subgroups.

Aim: To determined the effects of differentially expressed immune-related genes (DEIRGs) on the development, prognosis, tumor microenvironment (TME), and treatment response among GC patients with the expectation of providing new biomarkers for personalized treatment of GC populations.

TiOnanorod arrays/TiCTMXene nanosheet composites with efficient photocatalytic activity.

Semiconductor photocatalysis holds significant promise in addressing both environmental and energy challenges.

Highly Sensitive HS Gas Sensor Based on a Lead-Free CsCuI Perovskite Film at Room Temperature.

Recently, there have been reports of lead halide perovskite-based sensors demonstrating their potential for gas sensing applications. However, the toxicity of lead and the instability of lead-based perovskites have limited their applications. This study addressed this issue by developing a HS gas sensor based on a lead-free CsCuI film prepared using a one-step CVD method.

Betainization of Polydopamine/Polyethylenimine Coating for Universal Zwitterionization.

Biofoulants can adhere to multiple surfaces, degrading the performance of medical devices and industrial facilities and/or causing nosocomial infection. The surface immobilization of zwitterionic materials can prevent the initial attachment of the foulants but lacks extensive implementation. Herein, we propose a facile, universal, two-step surface modification strategy to improve fouling resistance.

The connection between cumulative weekly extracurricular training time, cumulative weekly extracurricular core training time and cadet performance is unknown.

Advances in Meta-Optics and Metasurfaces: Fundamentals and Applications.

Meta-optics based on metasurfaces that interact strongly with light has been an active area of research in recent years. The development of meta-optics has always been driven by human's pursuits of the ultimate miniaturization of optical elements, on-demand design and control of light beams, and processing hidden modalities of light. Underpinned by meta-optical physics, meta-optical devices have produced potentially disruptive applications in light manipulation and ultra-light optics.

Angular momentum holography via a minimalist metasurface for optical nested encryption.

Metasurfaces can perform high-performance multi-functional integration by manipulating the abundant physical dimensions of light, demonstrating great potential in high-capacity information technologies. The orbital angular momentum (OAM) and spin angular momentum (SAM) dimensions have been respectively explored as the independent carrier for information multiplexing. However, fully managing these two intrinsic properties in information multiplexing remains elusive.

Safety and efficacy of irinotecan, oxaliplatin, and capecitabine (XELOXIRI) regimen with or without targeted drugs in patients with metastatic colorectal cancer: a retrospective cohort study.

Background: Five-fluorouracil, folinic acid, oxaliplatin and irinotecan (FOLFOXIRI) regimen is used as the first-line treatment for metastatic colorectal cancer (mCRC). The use of capecitabine, an oral fluoropyrimidine pro-drug, is feasible and safe; hence, it provides an interesting alternative to 5-fluorouracil in the abovementioned regimen. This study aimed to evaluate the efficacy and safety of capecitabine, oxaliplatin, and irinotecan (XELOXIRI) regimen use with or without targeted drugs in Chinese patients with mCRC.

POLE/POLD1 mutation and tumor immunotherapy.

POLE and POLD1 encode the catalytic and proofreading subunits of DNA polymerase ε and polymerase δ, and play important roles in DNA replication and proofreading. POLE/POLD1 exonuclease domain mutations lead to loss of proofreading function, which causes the accumulation of mutant genes in cells. POLE/POLD1 mutations are not only closely related to tumor formation, but are also a potential molecular marker for predicting the efficacy of immunotherapy in pan-carcinomatous species.

Electric-Driven Polarization Meta-Optics for Tunable Edge-Enhanced Images.

In this study, we demonstrate an electrically driven, polarization-controlled metadevice to achieve tunable edge-enhanced images. The metadevice was elaborately designed by integrating single-layer metalens with a liquid-crystal plate to control the incident polarization. By modulating electric-driven voltages applied on the liquid-crystal plate, the metalens can provide two polarization-dependent phase profiles (hyperbolic phase and focusing spiral phase).

A 12-chemokine gene signature is associated with the enhanced immunogram scores and is relevant for precision immunotherapy.

Advances in the understanding of checkpoint blockade immunotherapy have suggested that boosting the cancer-immunity cycle (CIC) can help induce regression of tumors. However, good efficacy only occurs in a subset of patients. Predictive biomarkers that can reflect the tumor microenvironment (TME) and CIC may have great potential.
