Research Progress and Prospect of Single‐Atom Materials in Tumor Catalytic Therapy
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tumor catalytic therapy (TCT), an emerging therapeutic modality, exerts specific cytotoxic effects on tumor cells by catalyzing endogenous substances within the tumor microenvironment (TME)—including hydrogen peroxide (H2O2), glucose, and glutathione—to generate reactive oxygen species (ROS) or deplete protective biomolecules.

Shuitu Baochi Xuebao, 2008 对三江平原3种典型湿地(毛苔草湿地、小叶章湿地、岛状林湿地)的土壤酶活性、土壤养分进行了研究,探讨了不同湿地土壤酶与土壤养分及酶活性间的相关性。结果表明:不同湿地土壤酶活性和土壤养分含量有较大差异。土壤蔗糖酶、脲酶、过氧化氢酶、淀粉酶活性与土壤有机质、全氮、碱解氮含量变化趋势一致,表现为毛苔草湿地>小叶章湿地>岛状林湿地。酸性磷酸酶活性表现为岛状林湿地>毛苔草湿地>小叶章湿地;纤维素酶活性则表现为毛苔草湿地>岛状林湿地>小叶章湿地。经分析,土壤酶活性和养分密切相关,且酶活性间存在一定的相关关系,其中脲酶、

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Cisplatin‐related acute kidney injury (CP‐AKI) is a serious complication of cisplatin (CP) treated patients with cancer with high morbidity and mortality rates. It is directly related to the abnormal accumulation of CP in renal tubular epithelial cells, causing metabolic toxicity, DNA damage, and oxidative stress.
