Over the last decade, several compounds have been identified for the treatment of obesity. However, due to the complexity of the disease, many pharmacological interventions have raised concerns about their efficacy and safety. Therefore, it is important to discover new factors involved in the induction/progression of obesity. Adipose stromal/stem cells (ASCs), which are mostly isolated from subcutaneous adipose tissue, are the primary cells contributing to the expansion of fat mass. Like other cells, ASCs release nanoparticles known as extracellular vesicles (EVs), which are being actively studied for their potential applications in a variety of diseases. Here, we focused on the importance of the contribution of ASC-derived EVs in the regulation of metabolic processes. In addition, we outlined the advantages/disadvantages of the use of EVs as potential next-generation anti-obesity agents. 相似文献

Conclusions A study was made of the strength of abrasive grains of silicon nitride and of the wear resistance of silicon nitride material under conditions simulating the operation of abrasive grains in a grinding wheel. It is shown that in grain strength the new silicon nitride material is superior to diamond, Kubonit, and El'bor and inferior to Geksanit-A, while in wear resistance in the microcutting of unhardened steel it is comparable with Geksanit-A. On the basis of an electron microscopical examination of the surface structure of a worn microtool a mechanism is proposed for the wear of a material based on silicon nitride in the grinding of unhardened steel. A material based on silicon nitride could be successfully used in abrasive tools for the rough grinding of unhardened ferrous alloys.Translated from Poroshkovaya Metallurgiya, No. 5(173), pp. 34–37, May, 1977. 相似文献
