Identification of the suprachiasmatic nucleus venous portal system in the mammalian brain

September 25, 2021
Yao, Y., Taub, A.B., LeSauter, J. et al. Identification of the suprachiasmatic nucleus venous portal system in the mammalian brain. Nat Commun 12, 5643 (2021). https://doi.org/10.1038/s41467-021-25793-z Abstract There is only one known portal system in the mammalian brain – that of the pituitary gland, first identified in 1933 by Popa and Fielding. Here we describe a second portal pathway in...

Circadian Rhythms Within the Female HPG Axis: From Physiology to Etiology

July 12, 2021
Shuyi Shao, Huanqiang Zhao, Zhiying Lu, Xiaohong Lei, Ying Zhang, Circadian Rhythms Within the Female HPG Axis: From Physiology to Etiology, Endocrinology, Volume 162, Issue 8, August 2021, bqab117, https://doi.org/10.1210/endocr/bqab117 Abstract Declining female fertility has become a global health concern. It results partially from an abnormal circadian clock caused by unhealthy diet and sleep habits in modern...

Chronothyroidology: Chronobiological Aspects in Thyroid Function and Diseases

June 1, 2021
Bellastella G, Maiorino M, Scappaticcio L, et al. Chronothyroidology: Chronobiological Aspects in Thyroid Function and Diseases Life (Basel, Switzerland). 2021 May;11(5). Abstract  Chronobiology is the scientific discipline which considers biological phenomena in relation to time, which assumes itself biological identity. Many physiological processes are cyclically regulated by intrinsic clocks and many pathological events show a...
