Edelstyn N, Oldershaw A. After exposure, the levels of 2 waves in the hypothalamus increased more than those in the cortex, leading to a significant reduction in the deviation of the two EGGs. Cull-Candy SG, Leszkiewicz DN. J Mol Neurosci. 2 Researchers have been working. 2008;22:9927. It has been shown that neurons are sensitive to reductions in the availability of adenosine triphosphate (ATP), the main source of energy in mitochondria, which have been reported to be vulnerable to microwave radiation [118]. miRNAs are non-coding sequences with a length of approximately 22 nucleotides that have roles in cell development and differentiation and are also linked to signal transduction and tumorigenesis. In summary, there is evidence that microwave radiation can lead to alterations in protein synthesis or protein modifications; however, the results are controversial. Zhang proposed that the sex-dependent relationship between microwaves and the behavior of offspring may be related to sex hormones, and female rats may be equivalently protected by reducing oxidative stress levels.
