Anisotropic Single-Crystal Proton Conduction in a Sodium Chain-Based Coordination Polymer.

Coordination polymers (CPs) have been identified as promising candidate materials in the field of proton conduction owing to their customizable and diverse structures. However, research on CPs based on alkali metal ions has been less advanced, and the mechanism of proton transport in these materials remains unclear. Herein, a new coordination polymer, [Na(pytet)(Hdat)(HO)]·2HO (abbreviated as ) (pytet = pyrene-1,3,6,8-tetrasulfonate, dat = 2-hydroxy-4,6-diamino-1,3,5-triazine), has been synthesized based on the starting materials of Napytet and 2-chloro-4,6-diamino-1,3,5-triazine, with the latter undergoing in situ transformation to dat under hydrothermal conditions.

Design and synthesis of indol-2-one derivatives as potential RET inhibitors.

We synthesized and assessed five series of indol-2-one derivatives for their potential as RET kinase inhibitors. Notably, compounds B3, B6, D1, D2, D3, and D5 demonstrated significant inhibitory activity. Among these, D5 exhibited the best activity of inhibiting RET kinase, which provided reference for the subsequent development of RET kinase inhibitors as anti-thyroid cancer chemical.

Insights into the antifungal mechanism of Bacillus subtilis cyclic lipopeptide iturin A mediated by potassium ion channel.

Fungal infections pose severe and potentially lethal threats to plant, animal, and human health. Ergosterol has served as the primary target for developing antifungal medications. However, many antifungal drugs remain highly toxic to humans due to similarity in cell membrane composition between fungal and animal cells.

Substantial Energy Band Modulation of Semiconducting Hexagonal GaTe Quantum Wells by Layer Thickness and Mirror Twin Boundaries.

Exploring emerging two-dimensional (2D) van der Waals (vdW) semiconducting materials and precisely tuning their electronic properties at the atomic level have long been recognized as crucial issues for developing their high-end electronic and optoelectronic applications. As a III-VI semiconductor, ultrathin layered hexagonal GaTe (-GaTe) remains unexplored in terms of its intrinsic electronic properties and band engineering strategies. Herein, we report the successful synthesis of ultrathin -GaTe layers on a selected graphene/SiC(0001) substrate, via molecular beam epitaxy (MBE).

Patient's Healthy-Limb Motion Characteristic-Based Assist-As-Needed Control Strategy for Upper-Limb Rehabilitation Robots.

The implementation of a progressive rehabilitation training model to promote patients' motivation efforts can greatly restore damaged central nervous system function in patients. Patients' active engagement can be effectively stimulated by assist-as-needed (AAN) robot rehabilitation training. However, its application in robotic therapy has been hindered by a simple determination method of robot-assisted torque which focuses on the evaluation of only the affected limb's movement ability.

GPT-agents based on medical guidelines can improve the responsiveness and explainability of outcomes for traumatic brain injury rehabilitation.

This study explored the application of generative pre-trained transformer (GPT) agents based on medical guidelines using large language model (LLM) technology for traumatic brain injury (TBI) rehabilitation-related questions. To assess the effectiveness of multiple agents (GPT-agents) created using GPT-4, a comparison was conducted using direct GPT-4 as the control group (GPT-4). The GPT-agents comprised multiple agents with distinct functions, including "Medical Guideline Classification", "Question Retrieval", "Matching Evaluation", "Intelligent Question Answering (QA)", and "Results Evaluation and Source Citation".

Stoichiometry-Tunable Synthesis and Magnetic Property Exploration of Two-Dimensional Chromium Selenides.

Emerging 2D chromium-based dichalcogenides (CrX (X = S, Se, Te; 0 < ≤ 2)) have provoked enormous interests due to their abundant structures, intriguing electronic and magnetic properties, excellent environmental stability, and great application potentials in next generation electronics and spintronics devices. Achieving stoichiometry-controlled synthesis of 2D CrX is of paramount significance for such envisioned investigations. Herein, we report the stoichiometry-controlled syntheses of 2D chromium selenide (CrSe) materials (rhombohedral CrSe and monoclinic CrSe) via a Cr-self-intercalation route by designing two typical chemical vapor deposition (CVD) strategies.

A novel non-segmented inverted water outline rendering method can improve the tracking of responsible blood vessels for hemifacial spasm.

This study aimed to explore a novel, non-segmented based on inverted water outline, and rapid 3D rendering method for identifying the responsible blood vessels for hemifacial spasm. First, the software was developed using the free and open-source 3D Slicer to process magnetic resonance images. Outlines of the water region were extracted and rendered in a three-dimensional space.

Identification and Optimization of more Efficient Olivetolic Acid Synthases.

Olivetolic acid (OLA) is a key intermediate in cannabidiol (CBD) synthesis, and cannabinoids are important neuroactive drugs. However, the catalytic activity of olivetolic acid synthase (OLS), the key enzyme involved in OLA biosynthesis, remains low and its catalytic mechanism is unclear. In this study, we conducted a scrupulous screening of the pivotal rate-limiting enzyme and analyzed its amino acid sites that are critical to enzyme activity as validated by experiments.

Transfer and evolution of structured polarization in a double-V atomic system.

We numerically investigate the transfer of optical information from a vector-vortex control beam to an unstructured probe beam, as mediated by an atomic vapour. The right and left circular components of these beams drive the atomic transitions of a double-V system, with the atoms acting as a spatially varying circular birefringent medium. Modeling the propagation of the light fields, we find that, for short distances, the vectorial light structure is transferred from the control field to the probe.

Lone pair driven anisotropy in antimony chalcogenide semiconductors.

Antimony sulfide (SbS) and selenide (SbSe) have emerged as promising earth-abundant alternatives among thin-film photovoltaic compounds. A distinguishing feature of these materials is their anisotropic crystal structures, which are composed of quasi-one-dimensional (1D) [SbX] ribbons. The interaction between ribbons has been reported to be van der Waals (vdW) in nature and SbX are thus commonly classified in the literature as 1D semiconductors.

Middle Meningeal Artery Embolization for the Treatment of Bilateral Chronic Subdural Hematoma.

Bilateral chronic subdural hematoma (bCSDH) is a frequent condition commonly linked to the need for retreatment; however, the reason for this high retreatment rate remains unclear. The middle meningeal artery (MMA) was found to have a relationship with the occurrence and development of chronic subdural hematomas. This study examines a possible method to reduce bCSDH recurrence using bilateral MMA embolization combined with bilateral burr-hole drainage.
