IT was a time of happiness three years ago when Qian Kui, leader of the Chinese Gymnastics Team, took out a platinum ring with an inlaid diamond from a small velvet box and placed it on his wife’s finger. Qian, a senior team leader in his 50s, said to his wife with deep feeling, "Twenty-five years ago when we got married, we just put our single beds together. I didn’t bring you any gift, which I have long regretted. Today is the Silver anniversary of our marriage. Please

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.

作者：史可扬潘琳北京师范大学艺术与传媒学院北京1000875

国产动画片起点很高,20世纪也曾有过几次创作高潮,曾被誉为"中国动画学派"。但从20世纪90年代以来,随着外来动画片的强势入侵,国产动画片遇到发展瓶颈,出现主题与类型单一、低幼化现象突出、艺术水准不高、资源有待整合等问题,亟待改进。

In this study, a friction piezoelectric hybrid nanogenerator （HNG） with a sponge-like structure was developed. A novel temporary solution template process was proposed to create smaller, uniformly distributed pores within the sponge structure, allowing for the complete volatilization of the porous agent without causing structural defects. The output voltage of the porous HNG structure was nearly twice that of its solid structure, demonstrating superior electrical output performance. A peak-to-peak open circuit voltage of 168 V, a short circuit current density of 36.41μA cm-2, and a maximum power density of 32 W m-2were obtained at a load resistance of 200 MΩby periodically compressing an HNG with a dimension of 0.8 cm×0.8 cm. The generated electricity was sufficient to directly illuminate 180 tandem white LEDs and power small electronic devices. In addition, this study shows that the HNG could detect electrical signals from different parts of the human body during movement, suggesting significant potential for applications in energy harvesting and motion sensing.

在将地方政府行为划分为投资、收入与制度偏向性行为下,探讨过度财政分权引致公共服务供给效率损失的内在机制,并以体现人民发展性需求的公共文化服务为例,构建动态面板模型,采用SYS-GMM估计法进行经验验证,结果得出:(1)财政分权与公共文化服务供给效率间存在倒"U"型关系,在实现公共文化服务供给效率最大化的目标下,存在最优的财政分权边界;(2)在提高公共文化服务供给效率的目标下,最优财政分权边界存在"发达地区高、欠发达地区低"的区域特征,同时,政府治理能力优势区的财政分权适度范围也大于治理能力劣势区;(3)财政分权会通过地方政府行为影响公共文化服务供给效率:即适度分权能够扭转政府偏向性行为,提升公共文化服务供给效率,但过度分权会导致地方政府投资、收入与制度偏向,造成公共文化服务供给效率损失。
