The protective role of baicalin regulation of autophagy in cancers.

Autophagy is a conservative process of self degradation, in which abnormal organelles, proteins and other macromolecules are encapsulated and transferred to lysosomes for subsequent degradation. It maintains the intracellular balance, and responds to cellular conditions such as hunger or stress. To date, there are mainly three types of autophagy: macroautophagy, microautophagy and chaperone-mediated autophagy.

Modeling Hydrogen Markets: Energy System Model Development Status and Decarbonization Scenario Results.

Hydrogen can be used as an energy carrier and chemical feedstock to reduce greenhouse gas emissions, especially in difficult-to-decarbonize markets such as medium- and heavy-duty vehicles, aviation and maritime, iron and steel, and the production of fuels and chemicals.
