氯沙坦逆转维持性血液透析患者左心室肥厚与炎症和氧化应激的关系

open access: greenZhongguo shiyan zhenduanxue, 2012
目的研究氯沙坦对维持性血液透析(MHD)患者左心室肥厚(LVH)的影响及其与炎症和氧化应激的关系。方法将伴有LVH的MHD患者随机分为氯沙坦组和安慰剂组,每位患者服用氯沙坦50-100mg/日或安慰剂6个月,二维超声心动图检测心脏并计算左心室重量指数(LVMI),同时检测患者血清超敏-C反应蛋白(hs-CRP)和丙二醛(MDA),分析左心室重量指数的变化与hs-CRP和MDA的关系。结果治疗后6个月,氯沙坦组左心室重量指数,血清hs-CRP,丙二醛(MDA)水平均降低,与治疗前比均有统计学意义 ...

Renoprotective effects of brown adipose tissue activation in diabetic mice 棕色脂肪激活对糖尿病小鼠的肾脏保护作用

open access: yesJournal of Diabetes, Volume 11, Issue 12, Page 958-970, December 2019., 2019
Highlights This study demonstrates that of brown adipose tissue (BAT) with CL316,243 attenuates the progress of diabetic kidney disease (DKD). Mechanistically, the activation of BAT improved concentrations of circulating adipokines and microRNAs, which further affected the diabetic kidney and reactivated the AMP‐activated protein kinase/sirtuin 1 ...

Dual Checkpoint Inhibition with Ipilimumab plus Nivolumab After Progression on Sequential PD‐1/PDL‐1 Inhibitors Pembrolizumab and Atezolizumab in a Patient with Lynch Syndrome, Metastatic Colon, and Localized Urothelial Cancer

open access: yesThe Oncologist, Volume 24, Issue 11, Page 1416-1419, November 2019., 2019
Abstract Immune checkpoint blockade (ICB) is an approved therapy for advanced metastatic mismatch repair (MMR)‐deficient cancer regardless of tissue of origin. Although therapy is effective initially, recurrence rates are significant, and long‐term outcomes remain poor for most patients.

金属污染物通过铁死亡诱导神经毒性的研究进展

open access: yes浙江大学学报. 医学版
研究证实多种金属污染物暴露可诱导神经毒性,并与神经系统相关疾病的发生发展密切相关。铁死亡是细胞响应金属污染物暴露的细胞死亡方式,其与氧化应激、铁代谢、脂质过氧化等密切相关。近年研究发现,在铅、镉、锰、镍和锑等金属诱导的神经毒性中铁死亡发挥重要作用,如铅暴露通过氧化应激、铁代谢紊乱和炎症触发铁死亡;镉可通过铁离子代谢、氧化应激以及铁死亡相关信号通路引发铁死亡;锰可通过线粒体功能障碍、铁代谢紊乱和氧化应激促进铁死亡;镍可通过氧化应激影响线粒体功能以及破坏铁稳态并促进其中枢神经系统的脂质过氧化,激活铁死亡 ...

Molecular mechanism of the role of ROS signaling pathway in the antioxidant properties of TKE2 cells [PDF]

open access: yes, 2016
目的:目前ROS在干细胞生物学中的作用还没有得到充分说明和了解。在过氧化氢(H2O2)诱导的氧化应激条件下,我们比较小鼠角膜上皮祖细胞(TKE2)[1]和成熟的小鼠角膜上皮细胞(MCE)的不同反应,重点研究是角膜干细胞的抗氧化细胞特性及相关机制。 方法:以小鼠角膜上皮祖细胞(TKE2)和成熟的小鼠角膜上皮细胞(MCE)为细胞模型,通过CCK8细胞活性实验检测不同浓度H2O2对小鼠角膜上皮的祖细胞(TKE2)和成熟的小鼠角膜上皮细胞(MCE)的影响。利用H2O2处理细胞24小时后 ...

NIR‐Responsive Nano‐Integrated Magnesium Phosphate Cement Promotes Bone Regeneration via Osteoblast‐Exosome‐Osteoclast Crosstalk

open access: yesRare Metals, EarlyView.
ABSTRACT The limited osteogenic capacity of magnesium phosphate cement (MPC) has constrained its biomedical applications, underscoring the necessity to develop MPC with enhanced physical properties and bone‐forming capabilities. In this study, a multifunctional MPC system was developed by incorporating zoledronic acid‐loaded near‐infrared (NIR ...

The association between the antioxidant property and ROS system in murine corneal epithelial progenitor cells [PDF]

open access: yes, 2016
目的:活性氧(ROS)是体内产生的一种高活性分子,低浓度可以调节细胞代谢,基因转录和磷酸酶的活性,高浓度则会导致氧化损伤。目前,有关干细胞自身特性的研究越来越受到学者们的重视,但既往文献中关于干细胞对氧化应激反应以及应激条件下细胞内相关酶活性的变化规律却很少报道。本课题聚焦于,在过氧化氢(H2O2)诱导的氧化应激条件下,活性氧生成关键因子NOX4和抗氧化酶核转录因子NRF2在小鼠角膜上皮祖细胞(TKE2)和成熟的小鼠角膜上皮细胞(MCE)中的不同作用及相关机制。 方法:利用小鼠角膜上皮祖细胞(TKE2 ...

Study on the Function of the Neuron-Specific Protein TMEM59L in the Central Nervous System and in Oxidative Stress-Induced Cell Death [PDF]

open access: yes, 2016
细胞凋亡是受基因严格调控的、自然发生的程序性细胞死亡过程,而细胞自噬是细胞组分自我降解的过程,二者在发育、组织稳态以及病原体防御中扮演着重要角色。细胞凋亡和细胞自噬发生异常会引发多种疾病包括癌症和神经系统疾病。神经元对于氧化应激十分敏感,并易于受到活性氧的攻击;当神经元长期暴露于包括过氧化氢在内的活性氧的攻击时会引发细胞死亡,导致各种神经系统疾病。因此,鉴定参与神经元死亡的新基因蛋白并揭示其作用机制,将有助于阐明神经系统疾病的致病机理。 TMEM59L为新发现的脑特异性高表达蛋白 ...
