![]() ![]() ![]() To examine the possibility that this diurnal rhythm in the content and secretion of POMC-derived peptides resulted from diurnal changes in the biosynthesis of POMC, the concentration and rate of synthesis of POMC mRNA were examined. (19) Plasma and IL peptide levels were relatively constant during daylight hours (0600-1800 h), but increased after the onset of darkness and reached maximal concentrations at 0200 h.(18) 1) Diurnal patterns of the above-mentioned items were recorded, mutual relationships relationships between these items were revealed.(17) The syndrome of obstructive sleep apnoea is associated with an increased morbidity (the consequence of diurnal hypersomnolence and cardiovascular complications).(15) It has a relatively short half-life, and large diurnal fluctuations in serum concentrations occur, thus making it difficult to define clear relationships between individual serum concentrations and either therapeutic or adverse effects.(14) In one rat studied 30 days after ocular enucleation the diurnal rhythm in synthesis persisted however, relative to 4 days after enucleation the phase of the rhythm shifted about 90 degrees suggesting that light deprivation caused the rhythm to become free-running with a period slightly different from 24 h.(13) A diurnal pattern, however, could not be shown in the corticosterone response to immobilization.(12) The degree of change was comparable during the diurnal and nocturnal periods.(11) No IgE circadian rhythm was validated in healthy children while a large amplitude (approximately equal to 30% of the 24 hours mean) circadian rhythm with 2 diurnal peaks and a nocturnal trough was demonstrated (P less than 0.0023) in the asthmatics. ![]() (10) The diurnal rhythms of sleep-wake activity, motor activity, and Tbr were not affected in rats.(9) These findings would suggest that hereditary progressive dystonia with marked diurnal fluctuation could show not only a diurnal fluctuation but also age-dependent changes of symptoms.(8) When administered to adult patients with urge incontinence (generally as a 25mg twice-daily dose) terodiline reduces diurnal and nocturnal micturition frequency and incontinence episodes.(7) In order to clarify the diurnal pattern of secretion of plasma immunoreactive (IR) proopiomelanocortin (POMC)-derived peptides, IR-N-terminal peptide (Nt), IR-beta-endorphin (Ep), IR-beta-lipotropin (LPH), and IR-ACTH (ACTH) in normal subjects and in patients with Addison's disease and Cushing's disease, we measured these 4 peptides in the same plasma obtained at 0900 h and then every three hours until 0600 h at the next day.(6) The purpose of this study was to examine the pattern of diurnal variation of blood pressure in normotensive working women, and to assess the effect of work stress on this pattern.(5) Intraocular pressure was investigated with multiple 12-hour diurnal curves.(4) Study of the clinical characteristics of depressive state by hemisphere stroke with the use of symptom items of Zung scale and Hamilton scale showed that patients in depressive state with right hemisphere stroke had high values in symptom items considered close to the essence of endogenous depression such as depressed mood, suicide, diurnal variation, loss of weight, and paranoid symptoms, while patients in depressive state with left hemisphere stroke had high values in symptom items having a nuance of so-called neurotic depression such as psychic anxiety, hypochondriasis, and fatigue.(3) Seven days of constant light, however, reverses this diurnal variation such that plasma prolactin levels peak at 11:30 AM and reach a nadir at approximately 11:30 PM.(2) The amount of EB or progesterone injected seemed unimportant but, in either case, had to be given within a limited diurnal period of sensitivity.(1) Four of 18 patients showed no change over the twenty-four hours while 7 patients showed some variation without definite diurnal pattern.(a.) A small volume containing the daily service for the "little hours," viz., prime, tierce, sext, nones, vespers, and compline.(a.) Active by day - applied especially to the eagles and hawks among raptorial birds, and to butterflies (Diurna) among insects.(a.) Opening during the day, and closing at night - said of flowers or leaves.(a.) Daily recurring every day performed in a day going through its changes in a day constituting the measure of a day as, a diurnal fever a diurnal task diurnal aberration, or diurnal parallax the diurnal revolution of the earth.(a.) Relating to the daytime belonging to the period of daylight, distinguished from the night - opposed to nocturnal as, diurnal heat diurnal hours. ![]()
