This study aimed to investigate the effects of long-term glucose starvation on the lifespan of yeast cells by culturing in both standard and glucose-starved conditions. In this investigation yeast cells (BY4743 strain) were cultured in glucose-restricted YPD media (0.5 percent dextrose) to assess lifespan, growth-proliferation, autophagy, apoptosis, mtDNA abundance. The findings revealed that prolonged glucose restriction significantly extended chronological lifespan in yeast (p < 0.05). In order to decipher how starved yeast live chronologically longer, we tested mitochondrial association and found that calorie deprivation lowered the rate of mtDNA spontaneous mutation and increased mtDNA abundance which is a suggestive sign of mitobiogenesis. Furthermore, cells cultured on glucose-restricted media led to more autophagosome formation but less cell death. These results suggested that glucose restriction can enhance lifespan by improving overall cellular conditions.

Currently, several technologies are being intensively developed. In some of them, packed-bed systems play a central role: a heat transfer fluid heats up or releases heat from a porous solid that acts as a thermal energy reservoir. This work compiles their application to concepts such as concentrated solar power, pumped thermal energy storage, and compressed or liquid air energy storage. Different physical models with diverse refinement degrees and the corresponding computational schemes are comprehensively presented.
