MSMDL-DDI: Multi-Layer Soft Mask Dual-View Learning for Drug-Drug Interactions.

Drug-drug interactions (DDIs) occur when multiple medications are co-administered, potentially leading to adverse effects and compromising patient safety. However, existing DDI prediction methods often overlook the intricate interactions among chemical substructures within drugs, resulting in incomplete characterization of molecular properties. To address this limitation, we propose a novel model named Multi-Layer Soft Mask Dual-View Learning for Drug-Drug Interactions (MSMDL-DDI), which integrates dual-view learning with multi-layer soft mask graph neural networks to comprehensively capture intra- and inter-molecular interactions.

Quantifying the relative importance of natural and human factors on vegetation dynamics in China's western frontiers during 2010-2021.

Vegetation is a core component of terrestrial ecosystems, thus understanding the drivers of its dynamics is crucial for ecological conservation and management, especially in regions rich in natural resources but ecologically fragile. Here, we examined vegetation cover changes in China's western frontiers and quantified the relative importance of key drivers of vegetation dynamics. First, we employed the Dimidiate Pixel Model (DPM) via Google Earth Engine (GEE) to estimate fractional vegetation cover (FVC), followed by trend analysis using the Theil-Sen median and Mann-Kendall methods to examine FVC dynamics from 2010 to 2021.

Development of a rapid and sensitive RPA-CRISPR/Cas12a assay for non-invasive pre-implantation genetic testing.

Background: Pre-implantation genetic testing (PGT) is served as the primary technology for diagnosing genetic disorders. However, invasive operation may affect embryonic development, which indicates non-invasive methods might have important clinical value. Free DNA in blastocoele fluid provides the possibility for non-invasive diagnosis.

Peripheral Modification Strategy of Heavy Atom for High-Performance Multi-Resonance Thermally Activated Delayed Fluorescence Emitters.

Organic light-emitting materials with multi-resonance thermally activated delayed fluorescence (MR-TADF) have shown great potential for realizing highly efficient narrowband organic light-emitting diodes (OLEDs). However, the heavy efficiency roll-off caused by the slow reverse intersystem crossing (RISC) process remains a challenging issue for the further practical application of MR-TADF materials. Here, we develop two TADF emitters, BNDBT and BNDBF, in which the dibenzothiophene and dibenzofuran substituents are attached at the bottom of the B/N frameworks.

Bayesian learning-based agent negotiation model to support doctor-patient shared decision making.

Targeting pancreatic cancer glutamine dependency confers vulnerability to GPX4-dependent ferroptosis.

Pancreatic ductal adenocarcinoma (PDAC) relies heavily on glutamine (Gln) utilization to meet its metabolic and biosynthetic needs. How epigenetic regulators contribute to the metabolic flexibility and PDAC's response and adaptation to Gln scarcity in the tumor milieu remains largely unknown. Here, we elucidate that prolonged Gln restriction or treatment with the Gln antagonist, 6-diazo-5-oxo-L-norleucine (DON), leads to growth inhibition and ferroptosis program activation in PDAC.

Constructing an Organic-Inorganic Hybrid Solid-Electrolyte Interface In Situ via an Organo-Polysulfide Electrolyte Additive for Lithium-Sulfur Batteries.

Lithium (Li) metal's extremely high specific energy and low potential make it critical for high-performance batteries. However, uncontrolled dendrite growth and an unstable solid-electrolyte interphase (SEI) during repeated cycling still seriously hinder its practical application in Li metal batteries. Herein, we demonstrate a facile and effective approach to fabricate a flexible and robust hybrid SEI layer using two kinds of organo-polysulfides with different sulfur chain lengths [bis(3-(triethoxysilyl)propyl)disulfide (Si-O-2S) and bis(3-(triethoxysilyl)propyl)tetrasulfide (Si-O-4S)] as the additives in the electrolyte.
