Swanson C, Kohrt W, Wolfe P, Wright Jr K, Shea S, Cain S, et al.
Osteoporos Int . 2019 Aug; 30(12):2485-2493. PMID: 31446439
Introduction: A serum bone formation marker (procollagen type 1 N-terminal, P1NP) was lower after ~ 3 weeks of sleep restriction combined with circadian disruption. We now describe the time course...

Osteoporos Int . 2017 Jul; 28(11):3205-3213. PMID: 28744601
Introduction: The osteocyte exerts important effects on bone remodeling, but its rhythmicity and effect on the rhythms of other bone cells are not fully characterized. The purpose of this study...

Aeschbach D, Lockyer B, Dijk D, Lockley S, Nuwayser E, Nichols L, et al.
Clin Pharmacol Ther . 2009 Jul; 86(4):378-82. PMID: 19606092
Oral melatonin (MEL) can improve daytime sleep, but the hormone's short elimination half-life limits its use as a hypnotic in shift workers and individuals with jet lag or other sleep...

Czeisler C, Gooley J
Cold Spring Harb Symp Quant Biol . 2008 Apr; 72:579-97. PMID: 18419318
During the past 50 years, converging evidence reveals that the fundamental properties of the human circadian system are shared in common with those of other organisms. Concurrent data from multiple...

Scheer F, Zeitzer J, Ayas N, Brown R, Czeisler C, Shea S
Spinal Cord . 2005 Sep; 44(2):78-81. PMID: 16130027
Study Design: Case-controlled preliminary observational study. Objective: Melatonin is usually secreted only at night and may influence sleep. We previously found that complete cervical spinal cord injury (SCI) interrupts the...

Hilton M, Umali M, Czeisler C, Wyatt J, Shea S
Comput Cardiol . 2003 Nov; 27:197-200. PMID: 14632012
To determine if an endogenous circadian rhythmicity, independent from sleep/wake cycles, exists in autonomic nervous system (ANS) function, heart rate variability analysis of electrocardiogram R-R intervals was applied to data...

Klerman E, Shanahan T, Brotman D, Rimmer D, Emens J, Rizzo 3rd J, et al.
J Biol Rhythms . 2002 Dec; 17(6):548-55. PMID: 12465888
Ocular light exposure patterns are the primary stimuli for entraining the human circadian system to the local 24-h day. Many totally blind persons cannot use these stimuli and, therefore, have...

Cajochen C, Wyatt J, Czeisler C, Dijk D
Neuroscience . 2002 Oct; 114(4):1047-60. PMID: 12379258
The separate contribution of circadian rhythmicity and elapsed time awake on electroencephalographic (EEG) activity during wakefulness was assessed. Seven men lived in an environmental scheduling facility for 4 weeks and...

Wright Jr K, Hughes R, Kronauer R, Dijk D, Czeisler C
Proc Natl Acad Sci U S A . 2001 Nov; 98(24):14027-32. PMID: 11717461
Endogenous circadian clocks are robust regulators of physiology and behavior. Synchronization or entrainment of biological clocks to environmental time is adaptive and important for physiological homeostasis and for the proper...
