Immunosuppressant calcineurin inhibitors phase shift circadian rhythms and inhibit circadian responses to light
(Elsevier, 2008-10)
PP2B is a Ca2+/calmodulin-dependent protein phosphatase that is ubiquitously expressed in mammals. Among other actions, it is an effector mechanism in NMDA-mediated glutamate neurotransmission as well as a regulator of ...
Involvement of Dopamine Signaling in the Circadian Modulation of Interval Timing
(Wiley, 2014-03)
Duration discrimination within the seconds-to-minutes range, known as interval timing, involves the interaction of cortico-striatal circuits via dopaminergic-glutamatergic pathways. Besides interval timing, most (if not ...
Perinatal Programming of Circadian Clock-Stress Crosstalk
(Hindawi Publishing Corporation, 2018-02)
An intact communication between circadian clocks and the stress system is important for maintaining physiological homeostasis under resting conditions and in response to external stimuli. There is accumulating evidence for ...
Circadian disruption induced by tumor development in a murine model of melanoma
(Taylor & Francis, 2021)
Abstract: The circadian system induces oscillations in most physiological variables, with
periods close to 24 hours. Dysfunctions in clock-controlled body functions, such
as sleep disorders, as well as deregulation of ...
Aging with rhythmicity. Is it possible? Physical exercise as a pacemaker
(2020-11-15)
Aging is associated with gradual decline in numerous physiological processes, including a reduction in metabolic functions and immunological system. The circadian rhythm plays a vital role in health, and prolonged clock ...
Timed maternal melatonin treatment reverses circadian disruption of the fetal adrenal clock imposed by exposure to constant light
(2012)
Surprisingly, in our modern 24/7 society, there is scant information on the impact of developmental chronodisruption like the one experienced by shift worker pregnant women on fetal and postnatal physiology. There are ...
Do sleep abnormalities and misaligned sleep/circadian rhythm patterns represent early clinical characteristics for developing psychosis in high risk populations?
(Elsevier B.V., 2013-12-01)
Sleep architecture changes, such as slow-wave sleep (SWS) percentage variations and reductions in latency and density of rapid eye movement (REM), are found in most patients with schizophrenia and are considered to be an ...
The effect of constant darkness and circadian resynchronization on the recovery of alcohol hangover
(Elsevier Science, 2014-07)
Alcohol hangover (AH) is a particular state after binge-like drinking. AH begins when ethanol is absent in plasma and is characterized by a cluster of physical and psychological symptoms. Alcohol disrupts circadian patterns ...
Aging disrupts the temporal organization of antioxidant defenses in the heart of male rats and phase shifts circadian rhythms of systolic blood pressure
(Springer, 2021-12)
Aging is one of the main risk factors for cardiovascular diseases, and oxidative stress is a key element responsible for the development of age-related pathologies. In addition, the alteration of circadian rhythms also ...
Regulación circadiana, patrón horario de alimentación y sueño: enfoque en el problema de obesidad
(Sociedad Chilena de Nutrición, Bromatología y Toxicología, 2018)
El reloj biológico determina la mantención de los ritmos
circadianos en mamíferos, un tipo particular de ritmos
biológicos de duración cercana a 24 horas. Existe una
estrecha relación entre el funcionamiento del sistema ...
