A research team has developed an innovative nanodrug platform, NP_β-lap+PRO, for precise non-small cell lung cancer treatment. This system combines NQO1 bioactivation therapy with PROTAC technology and overcome drug solubility and targeting limitations. The design features a PLGA nanoparticle core co-encapsulating β-lapachone and a PARP1-targeting PROTAC molecule, shielded by a pH-responsive gadolinium-tannic acid shell. The platform's paramagnetic properties enable MRI tracking of drug distribution. Experiments confirm effective tumor accumulation and pH-triggered drug release. In A549 models, the system induces PARP1 degradation, disrupts DNA repair, and amplifies β-lap-NQO1-reactive oxygen species production, resulting in enhanced DNA damage and apoptosis.

Beryllium is valued for its light weight, strength, and heat resistance, making it important in aerospace, alloys, optics, and other advanced industries. But when beryllium enters wastewater during mining and processing, it can pose serious risks to ecosystems and human health. Long-term exposure to beryllium can damage the lungs and other organs, while beryllium-containing waste may threaten soil and water environments.

Biochar is often promoted as a promising tool for climate-smart agriculture, thanks to its ability to store carbon in soils and, in many cases, reduce emissions of nitrous oxide, a powerful greenhouse gas. But a study published in Biochar shows that the climate benefit of biochar is not guaranteed. The way biochar is produced, and the chemical groups present on its surface, can determine whether it helps reduce nitrous oxide or unexpectedly increases it.

A review of 56 field studies reveals that vegetative barriers reduce agricultural runoff by 40% and sediment loss by 63% on average, with even stronger performance in dry climates. Woody barriers outperform grass-only strips, but high variability across sites means effectiveness is hard to predict using simple design rules alone. The researchers offer a probabilistic model to help farmers and land managers make better decisions, positioning vegetative barriers as a practical alternative to cover crops in water-limited regions.

The study unveiled a novel regulation strategy that exhibits exceptional performance in gas sensing applications. This advanced material demonstrates outstanding selectivity, rapid response, and ultrahigh sensitivity, particularly in detecting ammonia (NH₃) molecules. The research, led by a team from East China University of Science and Technology, provides new insights into the gas sensing mechanisms of MXenes and introduces a synergistic strategy to optimize their performance.

The inherent structural instability and insufficient catalytic efficiency of enzymes may affect the reliability and sensitivity of enzyme-based immunosensors, especially in ultra-trace analysis. While covalent organic frameworks (COFs) offer excellent immobilization support due to their structural tunability and stability, conventional physical adsorption risks enzyme leakage, and their dense shells hinder mass transfer. Recent advances in defect engineering allow precise modulation of COF-enzyme interactions, enabling optimized enzyme conformation and activity, providing a promising platform for high-performance biosensors.

Sequential anthracycline and trastuzumab therapy, while highly effective for HER2-positive breast cancer, carries a significant risk of cardiotoxicity, necessitating protective strategies. Qizaobaoxin Decoction (QZBXD), a modified Chinese herbal formula, has demonstrated potential in mitigating such cardiac damage. This investigation systematically delineates the chemical composition of QZBXD and elucidates its cardioprotective efficacy and underlying mechanisms against doxorubicin/trastuzumab (DOX/TRZ)-induced injury. Utilizing UPLC-Q-TOF-MS/MS analysis, 83 compounds were identified, predominantly flavonoids, organic acids, and phthalides. In a rat model of DOX/TRZ-induced cardiotoxicity, QZBXD administration significantly improved cardiac functional parameters, including left ventricular ejection fraction and fractional shortening. It also reduced serum biomarkers of myocardial injury and ameliorated histopathological damage. Mechanistically, multi-omics approaches revealed that QZBXD restored gut microbiota diversity, enriching beneficial bacteria like Bacteroides while suppressing detrimental genera such as Ruminococcus and Oscillibacter. Concurrently, untargeted metabolomics indicated modulation of tryptophan and arachidonic acid metabolic pathways. An integrated analysis established a gut microbiota-metabolite-cardiac axis, demonstrating that QZBXD's cardioprotection is mediated through microbial remodeling and subsequent metabolic reprogramming, providing a pharmacological foundation for its clinical application.
