Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Metal‐Doped Carbon‐Based Nanomaterials: Photothermal Mechanism Innovation and Precision Therapy Advancement in Antibacterial and Antitumor Applications

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

氢谱磁共振代谢组学在2型糖尿病特征代谢物监测中的应用 [PDF]

open access: yes, 2018
目的应用氢谱磁共振(~1H-NMR)代谢组学方法研究2型糖尿病(T2DM)患者尿液中小分子代谢物代谢轮廓的变化。方法选择T2DM患者98例及健康对照组82例,利用~1H-NMR方法检测尿液的代谢轮廓,结合偏最小二乘判别分析法的模式识别分析方法,比较两组尿液中小分子代谢物差异。结果尿液的偏最小二乘判别分析法得分图显示与T2DM有关的特征代谢物包括乙酸、乳酸、牛磺酸、乙酰乙酸、葡萄糖、丙氨酸、甲基丙二酸、肌酐、柠檬酸、三甲胺等。结论糖代谢紊乱、氧化应激、氨基酸及脂类代谢异常 ...

Nitrogen deposition does not exacerbate phosphorus limitation of rhizosphere microbes in subalpine forests

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.
