Bone turnover, as assessed by several bone metabolic markers, has been reported to undergo a diurnal rhythm
The diurnal rhythm
of hOC has important implications for the selection of sampling times, e.
The biggest increase of serum FGF21 concentrations started around midnight (0000), reached its peak at around 0500 of the second day, and then slowly declined to a nadir in the afternoon, suggesting that FGF21 secretion is regulated by the diurnal rhythm
The Desa Adat community is a religio-cultural society, whose way of life is closely linked with the rites of passage and diurnal rhythms
3 (pg/mL) Cortisol, urinary 442 69 0 to 50 ([micro]g/24h) Table 3: Comparison of laboratory studies with adrenal Cushing's syndrome and normal pregnancy Test Adrenal Normal Cushing's pregnancy syndrome Morning serum Increased Increased cortisol Diurnal rhythm

Previous findings suggest that the transcriptional regulators upstream stimulatory factor 1 (USF1)  and USF2, which are related to genes involved in diurnal rhythm
, are potentially significant modulators of hepcidin expression (7).
Metabolic Cycles Are Linked to the Cardiovascular Diurnal Rhythm
in Rats with Essential Hypertension.
Occupational health, physiotherapy, behavioral physiology, public health, and work psychology specialists from Europe detail the health effects, risk assessment methods, interventions, and health and safety directives for work demanding high-energy metabolism, considerable muscle force, awkward postures, highly repetitive movements, high levels of mental load, and diurnal rhythm
disruption, and work in heat and cold, or prolonged, low-intensity, sedentary work.
In subjects with non-suppressed cortisol levels, diurnal rhythm
of cortisol was also evaluated (normal: midnight cortisol<7.
The effects of photoperiod and feeding on the diurnal rhythm
of circulating hormones in the red drum, Sciaenops ocellatus.
In other leafhopper and insect species, the diurnal rhythm
of egg hatch likely depends on temperature, with lower temperatures causing a more equal distribution of emergence over time.
