Hormone Research in Paediatrics, 1994
1997 marks the 25th anniversary of the discovery of the master circadian pacemaker in mammals in the hypothalamic suprachiasmatic nucleus. Remarkable progress has been made over the last 25 years in elucidating the physiological mechanisms involved in the entrainment, generation and expression of circadian rhythms at the cellular and systems levels ...

Circadian rhythms in the fetus
Molecular and Cellular Endocrinology, 2012Throughout gestation, the close relationship between mothers and their progeny ensures adequate development and a successful transition to postnatal life. By living inside the maternal compartment, the fetus is inevitably exposed to rhythms of the maternal internal milieu such as temperature; rhythms originated by maternal food intake and maternal ...

Circadian Rhythms in Hypertension
Scottish Medical Journal, 1981Continuous intra-arterial blood pressure recordings have been performed in 37 untreated ambulatory hypertensive subjects, who were investigated on an outpatient basis. Hourly data analysis demonstrated a circadian variation of both blood pressure and heart rate which were highest during the morning and fell during the late afternoon to reach a nadir ...

All forms of life, from the simplest cells to the most complex organisms, show periodicity in some of their biologic activities and functions. The most common of these rhythmic events are those that we refer to as "circadian" (circa, around; dias, day).

IFAC Proceedings Volumes, 2009
Abstract The HomeCare is a special monitoring system of the basic life functions. It has been primarily designed to take care for elderly people. But many of the designed devices could be used in the other branches of biotelemetry. Our HomeCare system is designed with respect to user comfort and it uses as cheap technical solutions as possible.

The Lancet Neurology, 2018
Advances in diagnostic technology, including chronic intracranial EEG recordings, have confirmed the clinical observation of different temporal patterns of epileptic activity and seizure occurrence over a 24-h period. The rhythmic patterns in epileptic activity and seizure occurrence are probably related to vigilance states and circadian variation in ...

Circadian Rhythms and Arthritis
Rheumatic Disease Clinics of North America, 2005The clinical symptoms of rheumatoid arthritis (RA) show a circadian variation; joint stiffness and pain are more prominent in the early morning. An altered functioning of the hypothalamic-pituitary-adrenal axis (cortisol) and of the pineal gland (melatonin) seems to be important factors in the perpetuation and clinical circadian symptoms of RA ...

Circadian rhythms are autonomous oscillators developed by the molecular circadian clock, essential for coordinating internal time with the external environment in a 24-h daily cycle. In mammals, this circadian clock system plays a major role in all physiological processes and severely affects human health.

Circadian rhythms in a nutshell
Physiological Genomics, 2000Edery, Isaac. Circadian rhythms in a nutshell. Physiol Genomics 3: 59–74, 2000.—Living organisms on this planet have adapted to the daily rotation of the earth on its axis. By means of endogenous circadian clocks that can be synchronized to the daily and seasonal changes in external time cues, most notably light and temperature, life forms anticipate ...

Seminars in Neurology, 2004
Circadian rhythm sleep disorders occur when individuals attempt to sleep at the wrong circadian time. The misalignment between the internal circadian timing system and the external environment is typically due to either an alteration in the functioning of the circadian timing system (e.g., delayed or advanced sleep phase disorder) or to changes in the ...
