Aspect Ratio‐Controlled Chiral Nanostructures for Dual‐Mode Breast Cancer Theranostics
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Chiral CdSe/CdS quantum dots (QDs) have emerged as promising platforms for precise cancer diagnosis and therapy due to their unique optical properties and biological interactions. In this study, we systematically investigated the role of aspect ratio (AR) modulation in ultrathin‐shelled chiral CdSe/CdS dot‐in‐rods (DRs) on their performance in

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

Zhongguo shiyan zhenduanxue, 2006 目的探讨神经节苷脂对小鼠迟发型变态反应的作用。方法体内利用肿瘤相关抗原皮下注射到小鼠背部皮下,每周一次,连续三周,使小鼠致敏,第四周对小鼠进行激发试验,刺激产生迟发型变态反应,即将表皮郎格罕氏细胞与神经节苷脂和肿瘤相关抗原共同孵育后注射到小鼠后足掌侧,分别于注射后24,48小时测量足掌肿胀程度来评估神经节苷脂对小鼠迟发型变态反应的作用。结果神经节苷脂可降低小鼠足掌肿胀程度,抑制小鼠迟发型变态反应。结论神经节苷脂具有抑制小鼠迟发型变态反应,同时说明神经节苷脂可以抑制表皮郎格罕氏细胞抗原提呈作用。

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 ...
