High-performance solid-state proton gating membranes based on two-dimensional hydrogen-bonded organic framework composites.

Biological ion channels exhibit strong gating effects due to their zero-current closed states. However, the gating capabilities of artificial nanochannels have typically fallen short of biological channels, primarily owing to the larger nanopores that fail to completely block ion transport in the off-states. Here, we demonstrate solid-state hydrogen-bonded organic frameworks-based membranes to achieve high-performance ambient humidity-controlled proton gating, accomplished by switching the proton transport pathway instead of relying on conventional ion blockage/activation effects.

Preclinical evidence that fibroblast growth factor receptor pathway inhibition by BGJ398 enhances small cell lung cancer response to chemotherapy.

Small cell lung cancer (SCLC) is a highly aggressive form of lung cancer with limited therapeutic options and poor prognosis. In this study, we explored the therapeutic potential of BGJ398, a selective fibroblast growth factor receptor (FGFR) inhibitor, alone and in combination with standard chemotherapy (cisplatin and paclitaxel) in SCLC. High-throughput screening of kinase inhibitors was performed on three SCLC cell lines (NCI-H446, NCI-H69, and NCI-H182), identifying BGJ398 as one of the most potent and selective inhibitors.

Targeted Modulation of the Meningeal Lymphatic Reverse Pathway for Immunotherapy of Breast Cancer Brain Metastases.

Treatment of tumor brain metastases remains challenging due to the ineffectiveness of drugs in crossing the blood-brain barrier (BBB). Here, we proposed a potential strategy to target and modulate the meningeal lymphatic system for immunotherapy of breast cancer brain metastases (BCBM) through peripheral administration. CT/fluorescence dual-modality imaging demonstrated that the phospholipid nanoprobe (α-PLNPs) through intracisternal magna injection effectively labeled and long-range tracked the meningeal lymphatic pathway from meningeal lymphatic vessels (MLVs) to periphery drainage cervical lymph nodes (CLNs).

Constructing Interfacial B-P Bonding Bridge to Promote S-Scheme Charge Migration within Heteroatom-Doped Carbon Nitride Homojunction for Efficient HO Photosynthesis.

The emerging step (S)-scheme heterojunction systems became a powerful strategy in promoting photogenerated charge separation while maintaining their high redox potentials. However, the weak interfacial interaction limits the charge migration rate in S-scheme heterojunctions. Herein, we construct a unique S-scheme carbon nitride (CN) homojunction with boron (B)-doped CN and phosphorus (P)-doped CN (B-CN/P-CN) for hydrogen peroxide (HO) photosynthesis.

Identification of novel phenolic inhibitors from traditional Chinese medicine against toxic α-synuclein aggregation via regulating phase separation.

Parkinson's disease (PD), a neurodegenerative disorder without cure, is characterized by the pathological aggregation of α-synuclein (α-Syn) in Lewy bodies. Classic deposition pathway and condensation pathway contribute to α-Syn aggregation, and liquid-liquid phase separation is the driving force for condensate formation, which subsequently undergo liquid-solid phase separation to form toxic fibrils. Traditional Chinese Medicine (TCM) has a long history in treating neurodegenerative disease, herein; we identified chemicals from herbs that inhibit α-Syn aggregation.

The immune microenvironment profoundly influences HCC progression, balancing immune suppression and antitumor responses. The Signal Transducer and Activator of Transcription 3 (STAT3) is central to this equilibrium, orchestrating immune dynamics and intertwining tumor progression with immune evasion mechanisms.

Preparation of anterolateral thigh flap from polio-affected lower limb: A safe surgical option that preserves patient's motor function.

The anterolateral thigh (ALT) flap is a commonly used donor site for reconstructive surger, especially in head and neck reconstructions. The flap's success is primarily determined by the quality and quantity of its perforating vessels, which is why clinicians typically prefer harvesting from a healthy leg with intact vascular anatomy. Poliomyelitis typically causes unilateral lower limb paralysis, resulting in muscle atrophy and deformities.

Integrating machine learning, suspect and nontarget screening reveal the interpretable fates of micropollutants and their transformation products in sludge.

Activated sludge enriches vast amounts of micropollutants (MPs) when wastewater is treated, posing potential environmental risks. While standard methods typically focus on target analysis of known compounds, the identity, structure, and concentration of transformation products (TPs) of MPs remain less understood. Here, we employed a novel approach that integrates machine learning for the quantification of nontarget TPs with advanced target, suspect, and nontarget screening strategies.
