Rare Metals, EarlyView.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

Danggui sini Decoction attenuated diabetic neuropathy in diabetic rats [PDF]
, 2016 摘要 目的：糖尿病神经病变（Diabeticneuropathy，DN)是糖尿病常见的并发症之一。我们以往的研究发现当归四逆汤加减方(DangguisiniDecoction，DSD)能够缓解糖尿病神经病变引起的疼痛。本实验拟观察当归四逆汤加减方(DSD)对糖尿病大鼠坐骨神经和脊髓中一氧化氮（nitricoxide，NO）、一氧化氮合酶（Inducednitricoxidesynthase，NOS）、抗氧化酶、凋亡相关蛋白和硝基酪氨酸（nitrotyrosine，NT）蛋白和对后肢爪垫表皮内神经纤维影响。

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Nanozymes have attracted considerable attention in cancer therapy due to their adjustable enzyme activity and high catalytic efficiency. However, they still face a major challenge from tumor metastasis. In this work, endogenous/exogenous dual‐responsive bimetallic hollow PdRu (termed HPdRu) nanozymes were prepared.

Cloning and characterization of emp53 from Echinococcus multilocularis [PDF]
, 2015 泡状棘球蚴病(Alveolarechinococcosis，AE)是由棘球绦虫属的多房棘球绦虫(Echinococcusmulticularia，Em)幼虫寄生所致的人畜共患寄生虫病，该病被认为是最致命的蠕虫感染病。泡状棘球蚴在宿主体内生长就必须存在一套防御系统来抵御氧化损伤、维持基因组稳定以及细胞凋亡，肿瘤抑制基因p53被誉为“基因组的卫士”，在应对一系列的刺激和损伤时起了非常重要的作用。 尽管p53在细胞的增殖、分化或凋亡中具有重要的作用，但是到目前为止在寄生蠕虫领域还没有p53相关蛋白的研究报道 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The escalating issue of drug‐resistant pathogens, largely driven by the overuse of conventional antibiotics, has become a significant global health threat. Developing alternative therapeutic strategies and fabricating natural biological enzyme materials that mimic the high efficiency, selectivity, and mild‐operating conditions of natural ...

Calcitriol inhibits advanced glycation end product (AGE)-elicited mesangial cell damage by sequestrated RAGE-NF-κB Signaling [PDF]
, 2015 维生素D是通过与骨，甲状旁腺，肾脏和胃肠道的相互作用调节钙稳态，已经被用来作为糖尿病肾病（DKD）的常规用药。几个临床试验表明，维生素D在糖尿病肾病的治疗中，存在着减少蛋白尿和减缓肾损伤的抗炎作用，但其作用机制尚不清楚。而晚期糖化终产物（AGEs）在血浆和肾的积累，在糖尿病肾病中，是大家公认的促炎症分子。为了探索这种抗炎作用，我们设计实验。 研究目的：探寻骨化三醇减少AGEs引起的人肾系膜细胞炎症反应的机制，具体是探寻骨化三醇对AGEs引起的人系膜细胞表达白细胞介素-6（IL-6）和单核细胞趋化因子 ...

Linchuang shenzangbing zazhi, 2015 随着对慢性肾脏病（chronic kidney disease,CKD）进展机制的不断探索发现,氧化应激、炎症反应与CKD的发生、发展密切相关,且随肾功能损害加重,其炎症及氧化应激状态增强,并且肾功能进展越快者炎症及氧化应激状态越明显[1]。本文以替米沙坦为对照药,探讨尿毒清颗粒对CKD患者肾功能的临床疗效及其对CKD患者氧化应激、微炎症状态的影响 ...

Zhejiang Daxue xuebao. Lixue ban, 2008 采用利用内源荧光、1-苯氨基萘-8-磺酸(ANS)荧光、酶活性的测定以及动力学分析等手段，研究肌酸激酶在氧化型的二硫基苏糖醇(DTT)溶液中的结构与活性的变化.结果表明：随着氧化型DTT浓度的增加，肌酸激酶的活性逐渐丧失，直至完全失活，并伴随着构象的变化.肌酸激酶起初微小的结构变化就会导致酶活性的迅速丧失，而且其的失活先于明显可测的整体构象变化，酶分子的活性部位处于柔性区域内.另外，随着氧化型DTT浓度的提高，肌酸激酶的内源荧光发射峰位明显地红移，外源ANS荧光强度显著增强，即酶分子的疏水面加大 ...
