Key Laboratory for Green Organic Synthesis and Application of Hunan Province, Key Laboratory of Environmentally Friendly Chemistry and Application of Ministry of Education, College of Chemistry, Xiangtan University, Xiangtan 411105, China. Electronic address:

Most of the photocatalytic reactions are currently driven by high-energy light (UV, blue light), which inevitably leads to side reactions and co-catalyst deactivation. Therefore, there is an urgent need to prepare novel photocatalysts with low-energy photocatalytic properties. Herein, we report a rational molecular design of covalent organic frameworks (COFs) equipped with donor-π-acceptor systems with different π-bridges (aromatic ring, mono- and bis-alkynyl).

State Key Laboratory of Quality Research in Chinese Medicine, Institute of Chinese Medical Sciences, University of Macau, Macau SAR, China. Electronic address:

Background: Gut microbiota plays an important role in multiple human physiological processes and an imbalance in it, including the species, abundance, and metabolites can lead to diseases. These enteric microorganisms modulate immune homeostasis by presenting a myriad of antigenic determinants and microbial metabolites. Medicinal and food homologous (MFH) plants, edible herbal materials for both medicine and food, are important parts of Traditional Chinese Medicine (TCM).

CO sequestration technologies (CSTs) allow for increased CO emissions without exceeding a chosen temperature limit by creating additional carbon budgets. While these CO sequestration technologies offer low-cost routes to net-zero emissions, namely, the CST benefits, they impede progress to the Sustainable Development Goals, namely, the CST disbenefits. Focusing on China, we assess both the CST disbenefits and benefits in the climate-energy-air-health cascade by an integrated modeling framework.

Due to the large size and lack of fine-grained annotation, Whole Slide Images (WSIs) analysis is commonly approached as a Multiple Instance Learning (MIL) problem. However, previous studies only learn from training data, posing a stark contrast to how human clinicians teach each other and reason about histopathologic entities and factors. Here, we present a novel knowledge concept-based MIL framework, named ConcepPath, to fill this gap.

Establishing normative values and understanding how proprioception varies among body parts is crucial. However, the variability across individuals, especially adolescents, makes it difficult to establish norms. This prevents further investigation into classifying patients with abnormal proprioception.

Biological systems are complex, encompassing intertwined spatial, molecular and functional features. However, methodological constraints limit the completeness of information that can be extracted. Here, we report the development of INSIHGT, a non-destructive, accessible three-dimensional (3D) spatial biology method utilizing superchaotropes and host-guest chemistry to achieve homogeneous, deep penetration of macromolecular probes up to centimeter scales, providing reliable semi-quantitative signals throughout the tissue volume.

The lack of a robust system to reproducibly propagate HRV-C, a family of viruses refractory to cultivation in standard cell lines, has substantially hindered our understanding of this common respiratory pathogen. We sought to develop an organoid-based system to reproducibly propagate HRV-C, and characterize virus-host interaction using respiratory organoids. We demonstrate that airway organoids sustain serial virus passage with the aid of CYT387-mediated immunosuppression, whereas nasal organoids that more closely simulate the upper airway achieve this without any intervention.

Proper exposure settings are crucial for modern machine vision cameras to accurately convert light into clear images. However, traditional auto-exposure solutions are vulnerable to illumination changes, splitting the continuous acquisition of unsaturated images, which significantly degrades the overall performance of underlying intelligent systems. Here we present the neuromorphic exposure control (NEC) system.

State Key Laboratory of Oral Diseases, School of Chemical Engineering, National Center for Stomatology & National Clinical Research Center for Oral Diseases, Sichuan University, Chengdu, 610041, China.

Intractable implant-associated infections (IAIs) are the primary cause of prosthetic implant failure, particularly in the context of diabetes mellitus. There is an urgent need to design and construct versatile engineered implants integrated with cascade amplification therapeutic modality to significantly improve the treatment of diabetic IAIs. To address this issue, a multi-functional MXene/AgPO@glucose oxidase bio-heterojunction enzyme (M/A@GOx bio-HJzyme) coating is developed, which is decorated with an inert sulfonated polyetheretherketone implant (SP-M/A@G) via hydrothermal treatment and layered deposition.

Background: The lack of clearly defined neuromodulation targets has contributed to the inconsistent results of real-time fMRI-based neurofeedback (rt-fMRI-NF) for the treatment of chronic pain. Functional neurosurgery (funcSurg) approaches have shown more consistent effects in reducing pain in patients with severe chronic pain.

Objective: This study aims to redefine rt-fMRI-NF targets for chronic pain management informed by funcSurg studies.

Bioprinting has emerged as a powerful manufacturing platform for tissue engineering, enabling the fabrication of 3D living structures by assembling living cells, biological molecules, and biomaterials into these structures. Among various biomaterials, hydrogels have been increasingly used in developing bioinks suitable for 3D bioprinting for diverse human body tissues and organs. In particular, hydrogel blends combining gelatin and gelatin methacryloyl (GelMA; "GG hydrogels") receive significant attention for 3D bioprinting owing to their many advantages, such as excellent biocompatibility, biodegradability, intrinsic bioactive groups, and polymer networks that combine the thermoresponsive gelation feature of gelatin and chemically crosslinkable attribute of GelMA.

Human long bones exhibit pore size gradients with small pores in the exterior cortical bone and large pores in the interior cancellous bone. However, most current bone tissue engineering (BTE) scaffolds only have homogeneous porous structures that do not resemble the graded architectures of natural bones. Pore-size graded (PSG) scaffolds are attractive for BTE since they can provide biomimicking porous structures that may lead to enhanced bone tissue regeneration.
