Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The efficacy of immunotherapy in triple‐negative breast cancer (TNBC) is often limited, whereas the immunotherapeutic potential of pyroptosis is frequently undermined by a compensatory surge in mitophagy. To address this challenge, this study developed a reactive oxygen species (ROS)‐responsive and mitochondria‐targeted nanomicelle (POM@CTT ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Zirconium dioxide (ZrO2) thin films are critical materials owing to their thermal stability, mechanical durability, and optical transparency enabling applications in photonic, sensing, and electronic devices. However, achieving uniform deposition via plasma‐enhanced chemical vapor deposition (PE‐CVD) has remained challenging due to poor ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2023 线粒体电压依赖性阴离子通道1（VDAC1）是线粒体外膜上重要的通道蛋白，调控线粒体自噬，参与炎症因子的调节及炎症小体的激活，从而对炎症反应起着重要的作用。睡眠呼吸暂停综合征（OSAS）患者由于间歇性缺氧，氧化应激增加引起神经炎症，导致慢性损伤和神经元细胞凋亡，最终形成认知功能障碍。由于炎症在OSAS患者认知障碍的形成过程中起着重要的作用，而VDAC1调控着炎症小体的激活，因此本文综述了OSAS与炎症、OSAS与自噬之间的关系，并分析了VDAC1介导的炎症与线粒体自噬之间的相互作用 ...

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...
