缺血性卒中后氧化应激的失衡与卒中致残增加和不良预后相关。表观遗传调控可以通过DNA甲基化、组蛋白修饰等方式影响氧化应激,进而在卒中的进展中发挥作用。本文概述表观遗传调控在卒中后氧化应激反应过程中的作用,以期为缺血性卒中的治疗提供新的思路。 Abstract: Imbalance of oxidative stress after ischemic stroke is associated with increased disability risk and poor functional ...

Effect of Highland Barley Extract Intervention on Skeletal Muscle Atrophy of Aged Mice(青稞提取物干预对老年小鼠骨骼肌萎缩的影响) [PDF]
The significant decline in skeletal muscle mass and function due to aging is closely associated with an age-related increment of oxidative stress. Highland barley is rich in bioactive components such as polyphenols and flavonoids, which exert strong ...

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 ...

ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.

阿尔茨海默病(AD)是常见的神经变性病,氧化应激在AD 早期病理发生和发展中起到了重要的作用。在老化、早老素 1(PS1)突变及环境等共同作用下,脑内出现过度氧化应激,促进β-淀粉样蛋白(Aβ)的形成,Aβ可能为氧化应激作用下的适应性产物。氧自由基产生与清除的失衡还可导致海马神经元自噬功能异常,诱导细胞从自噬到死亡,其可能的机制是Notch1 通路失调。Notch1 通路的失调导致机体抗氧化应激能力丧失和淀粉样前体蛋白(APP)剪切增多、Aβ沉积,最终引起AD 病理的发生与发展 ...

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy
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.

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
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 ...

ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.
