Medical and Biotech [MESH] Definitions
The regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.
Period Circadian Proteins
Circadian rhythm signaling proteins that influence circadian clock by interacting with other circadian regulatory proteins and transporting them into the CELL NUCLEUS.
Circadian Rhythm Signaling Peptides And Proteins
A broad category of proteins that regulate the CIRCADIAN RHYTHM of an organism. Included here are proteins that transmit intracellular and intercellular signals in a chronological manner along with proteins that sense light and time-dependent changes in the environment such as the PHOTOPERIOD.
Biological mechanism that controls CIRCADIAN RHYTHM. Circadian clocks exist in the simplest form in cyanobacteria and as more complex systems in fungi, plants, and animals. In humans the system includes photoresponsive RETINAL GANGLION CELLS and the SUPRACHIASMATIC NUCLEUS that acts as the central oscillator.
Ultrasonography, Doppler, Duplex
Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.
Background- The incidence of syncope exhibits a daily pattern with more occurrences in the morning, possibly as a result of influences from the endogenous circadian system and/or the daily pattern of...
Aim: Rev-Erb β gene plays crucial roles in circadian rhythm, lipid and glucose metabolism, and several diseases. The molecular mechanisms of the transcriptional regulation of Rev-Erb β that generate...
Mammalian circadian rhythms have been extensively studied for many years and many computational models have been presented. Most of the circadian rhythms are based on interlocked positive and negative...
The aim of this study is to analyze the presence of circadian rhythm in the time of onset of symptoms of acute myocardial infarction treated by a prehospital emergency system and the influence of modi...
ABSTRACT: BACKGROUND: In university health care settings, students with psychosomatic complaints often have chronotypic problems. For this reason, we investigated a potential connection between psycho...
The purpose of this study is to assess the safety and efficacy of VEC-162 compared to matching placebo on circadian phase shift and sleep parameters.
Rationale: Investigation of the circadian rhythm of erythropoietin and melatonin in patients with various degrees of renal insufficiency Objectives: Primary objective: Is there a c...
Sleep problems can lead to a bad quality of life and a raise of morbidity, also in dialysis patients. Sleep problems can be caused by a disturbance of circadian rhythms in our body. For a...
We previously evidenced in both animal models and patients that a short duration ambulatory anesthesia impacts the circadian rest-activity biological rhythm, at least during the first 3...
This study's first aim is to widen the knowledge of the characteristics of delayed sleep phase disorder (DSPS) by focusing on the circadian rhythms of appetite regulation factors and their...
