对蒙煤与平七煤两种单煤及其按照不同比例组成的混煤,分别在O_2/CO_2和O_2/N_2气氛下,采用管式炉燃烧制取灰样;对灰样进行灰熔点、XRD及同步热分析(TG/DSC)测试,并进行相关热力学计算,分析了O_2/CO_2燃烧方式对混煤灰中矿物质间反应的影响。结果表明,常规灰熔点测试方法测得的两种气氛下的混煤灰熔点没有明显差别。O_2/CO_2气氛促进了煤灰/混煤灰中钙的碳酸化,且明显抑制了高温下CaCO_3的分解。气氛的改变影响了含钙矿物的转化,进而影响了混煤中钙与莫来石反应生成低温共熔物;O_2/CO_2气氛下钙更易于与莫来石发生反应生成低温共熔物,从而会增加结渣倾向。当混煤中蒙煤比例达到或大于75%时,随着蒙煤比例的逐渐增加,莫来石含量减少,O_2/CO_2气氛对钙与莫来石之间的反应影响减弱,但对含铁矿物的影响更加明显,使其更易于生成含铁玻璃体,从而也会增加结渣倾向。

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.

与正常组织相比,实体瘤生长的微环境更加恶劣。那么,为何在如此恶劣的生长环境下,肿瘤细胞仍能顽强生存,更有胜者转化成耐药肿瘤细胞,造成临床难以治疗的困难局面。该文拟以低营养模拟肿瘤的内部环境,研究野生型与耐药型细胞生长状态和生长需求存在的差异,进而解析其具体原因。该文以人乳腺癌MCF-7细胞的野生型和耐阿霉素型细胞为研究对象,通过对细胞增殖能力、细胞迁移和血管内皮生长因子(vascular endothelial growth factor,VEGF)分泌等实验分析发现,在低营养条件下,耐药型细胞的增殖能力和迁移能力远高于野生型细胞,而且耐药型细胞能分泌更多的VEGF。该研究结果表明,在营养胁迫条件下,耐药型细胞的生存能力更强,VEGF的高分泌可能是促进其快速生长的重要原因。
