Circadian mesor of recumbent pulse--cost-effective predictor of doxorubicin-induced congestive heart failure.

abstract：:High fat diet (HFD) consumption alters the synchronized circadian timing system resulting in harmful loss, gain or shift of transcriptional oscillations. The aryl hydrocarbon receptor (AhR) shares structural homology to clock genes, containing both PAS domains and basic helix-loop helix structural motifs, allowing for...
