Recent Progress in the Development of Metal‐Based Radiosensitizations for Cancer Therapy: A Review
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Radiotherapy (RT) remains an indispensable means in cancer treatment; however, its therapeutic efficacy is often limited by tumor radioresistance and side effect of damage to healthy tissue. The advances in nanotechnology have propelled metal radiosensitizers to forefront of precision medicine.

A preliminary study on relation of seven metals content with humen semen quality [PDF]
, 2010 本实验通过电感耦合等离子体质谱法（ICP-MS）测定精浆中七种金属（铅、镉、铬、锰、铜、砷、硒）的含量并检测精浆酸性磷酸酶（ACP）和α-葡萄糖苷酶的活性，与精液各项指标（精子密度、精子活动率、精子正常形态率等）进行相关性分析。得到以下结果：1.金属元素含量与精子活动率之间存在负相关性。精子活动率越高的样品中，金属含量越低；除镉元素外，其他元素含量与精子密度呈负相关。其中：铜、砷、铅三种元素与密度呈显著相关（PCu=0.002，PMn=0.007，PPb=0.009）；除硒、镉外 ...

Rare Metals, Volume 43, Issue 8, Page 3702-3712, August 2024.Graphical abstract AbstractThe highly reversible insertion/extraction of large‐radius K+ into electrode materials remains a tough goal, especially for conversion‐type materials. Herein, we design a current collector‐integrated electrode (N–CoSe/CoSe2–C@Cu) as an advanced anode for potassium‐ion battery (PIBs).

Effecf of Tributyltin on the Development of Gonad in Male Mice and Potential Mechanism [PDF]
, 2008 三丁基锡（TBT）是一种重要的有机锡类化合物，在环境中大量使用，具有很强的毒性。近年，许多研究表明TBT对软体动物和鱼类生殖机能产生影响，但是有关对哺乳动物的生殖影响报道较少。本实验以青春期雄性小鼠为研究对象，在生态条件下和环境污染浓度范围内，采用不同浓度TBT（0.5、5、50μg/kg）对其进行灌胃染毒，每三天灌胃一次，暴露30天。通过光学显微镜观察精子质量；放射免疫法检测睾丸性激素水平；westernblotting方法检测性激素受体水平以及PCNA表达水平；并利用TUNEL法检测细胞凋亡情况 ...
