基于生物秀丽隐杆线虫模型探究卡拉胶寡糖的抗衰老能力。采用含不同质量浓度(0.25、0.50、1.00 mg/mL)卡拉胶寡糖的大肠埃希氏菌液(OP50)饲喂线虫,以饲喂OP50菌液组作为空白对照,观察卡拉胶寡糖对线虫的寿命、繁殖力、体长体宽、运动能力和应激能力等健康指数的影响,以及测定线虫体内活性氧(reactive oxygen species,ROS)含量和抗氧化酶活性,探究卡拉胶寡糖对线虫抗衰老的影响。与对照组线虫相比,各浓度的分子质量为1.58 kDa的卡拉胶寡糖(KCO-5)均可延长线虫寿命,能将线虫的寿命延长4.18%~16.48%;改善了线虫的体长体宽、运动和应激能力,降低了其体内脂褐素积累水平,且不会损伤繁殖能力。KCO-5能够显著降低线虫体内ROS和丙二醛含量,并提高了总超氧化物歧化酶、过氧化氢酶和还原型谷胱甘肽的活性,且呈剂量依赖性(P<0.05)。结果表明,KCO-5中和了过量产生的ROS,增强了线虫的抗逆性,并延长了寿命。综上,卡拉胶寡糖具有抗衰老功效,是减少氧化应激、改善健康寿命的功能食品或药物替代品的一种新的可能来源。

Current treatments for epilepsy can only manage the symptoms of the condition but cannot alter the initial onset or halt the progression of the disease. Consequently, it is crucial to identify drugs that can target novel cellular and molecular mechanisms and mechanisms of action. Increasing evidence suggests that axon guidance molecules play a role in the structural and functional modifications of neural networks and that the dysregulation of these molecules is associated with epilepsy susceptibility. In this review, we discuss the essential role of axon guidance molecules in neuronal activity in patients with epilepsy as well as the impact of these molecules on synaptic plasticity and brain tissue remodeling. Furthermore, we examine the relationship between axon guidance molecules and neuroinflammation, as well as the structural changes in specific brain regions that contribute to the development of epilepsy. Ample evidence indicates that axon guidance molecules, including semaphorins and ephrins, play a fundamental role in guiding axon growth and the establishment of synaptic connections. Deviations in their expression or function can disrupt neuronal connections, ultimately leading to epileptic seizures. The remodeling of neural networks is a significant characteristic of epilepsy, with axon guidance molecules playing a role in the dynamic reorganization of neural circuits. This, in turn, affects synapse formation and elimination. Dysregulation of these molecules can upset the delicate balance between excitation and inhibition within a neural network, thereby increasing the risk of overexcitation and the development of epilepsy. Inflammatory signals can regulate the expression and function of axon guidance molecules, thus influencing axonal growth, axon orientation, and synaptic plasticity. The dysregulation of neuroinflammation can intensify neuronal dysfunction and contribute to the occurrence of epilepsy. This review delves into the mechanisms associated with

Hepatic ischemia-reperfusion injury（HIRI） is characterized by mitochondrial dysfunction and oxidative stress. Monitoring mitochondrial hydrogen peroxide（mtH2O2） levels in real-time through super-resolution imaging is crucial for elucidating its distribution in live cells and its mechanism of action during HIRI. However, low-background fluorogenic probes have been overlooked in the context of super-resolution imaging. In this study, we developed a low-background fluorogenic probe（MitoWG） with the potential for super-resolution morphology-correlated mitochondrial identification to track the fluctuates of mtH2O2in HIRI. Activation of the desirable fluorescence properties of the probe by mtH2O2was confirmed using structural illumination microscopy（SIM）, enabling high-quality mitochondrial imaging with exceptional specificity and *** in mtH2O2levels were successfully observed in both cellular and rat models of HIRI. Furthermore, we associated the decline in mitochondrial redox homeostasis with accelerated mtH2O2production during HIRI, which triggered mitophagy deficiency and led to cell death. In conclusion, Mito-WG possesses excellent photophysical and low-background properties for SIM imaging, making it a promising tool for mtH2O2tracking in HIRI research and clinical diagnosis.
