Assaying locomotor activity to study circadian rhythms and sleep parameters in Drosophila. [PDF]

, 2010
Most life forms exhibit daily rhythms in cellular, physiological and behavioral phenomena that are driven by endogenous circadian (≡24 hr) pacemakers or clocks. Malfunctions in the human circadian system are associated with numerous diseases or disorders.

Circadian Rhythm and Alzheimer’s Disease

Medical Science, 2018
Alzheimer’s disease (AD) is a neurodegenerative disorder with a growing epidemiological importance characterized by significant disease burden. Sleep-related pathological symptomatology often accompanies AD.

CHRONO and DEC1/DEC2 compensate for lack of CRY1/CRY2 in expression of coherent circadian rhythm but not in generation of circadian oscillation in the neonatal mouse SCN

Scientific Reports, 2021
Clock genes Cry1 and Cry2, inhibitory components of core molecular feedback loop, are regarded as critical molecules for the circadian rhythm generation in mammals.

Non-dipping nocturnal blood pressure and psychosis parameters in Parkinson disease [PDF]

, 2015
Conclusion: These results suggest that, among PD patients, a non-dipping circadian rhythm is associated with more severe symptoms of psychosis than is a dipping circadian rhythm.

Circadian rhythm in bipolar disorder: A review of the literature

Psychiatry and Clinical Neurosciences, 2018
Sleep disturbances and circadian rhythm dysfunction have been widely demonstrated in patients with bipolar disorder (BD). Irregularity of the sleep–wake rhythm, eveningness chronotype, abnormality of melatonin secretion, vulnerability of clock genes, and

Disruption in the regulation of casein kinase 2 in circadian rhythm leads to pathological states: cancer, diabetes and neurodegenerative disorders

Frontiers in Molecular Neuroscience, 2023
IntroductionCircadian rhythm maintains the sleep–wake cycle in biological systems. Various biological activities are regulated and modulated by the circadian rhythm, disruption of which can result in onset of diseases.

Light masking of the circatidal activity rhythm in the mangrove cricket Apteronemobius asahinai [PDF]

, 2013
Apteronemobius asahinai shows two rhythms in its locomotor activity. One is the circatidal rhythm, which produces active and inactive phases, and the other is the circadian rhythm, which suppresses the intensity of the activity of the circatidal active ...

Circadian rhythm–dependent and circadian rhythm–independent impacts of the molecular clock on type 3 innate lymphoid cells

Science immunology, 2019
Clock protein REV-ERBα influences development of type 3 innate lymphoid cells in a circadian-independent manner (see the related Focus by Mortha and Research Article by Teng et al.).

The impact of short-term changes in sleeping and eating patterns on glucometabolic health and gut microbiota in healthy young adults: a proof-of-concept controlled feeding study

Food Science and Human Wellness
Epidemiological studies showed that night workers are at higher risk of developing chronic metabolic diseases. However, no study has investigated the changes in circadian rhythms caused by a combined effect of sleep and diet in a real-life setting on ...

The mammalian circadian system: a hierarchical multi-oscillator structure for generating circadian rhythm

Journal of Physiological Sciences, 2018
The circadian nature of physiology and behavior is regulated by a circadian clock that generates intrinsic rhythms with a periodicity of approximately 24 h. The mammalian circadian system is composed of a hierarchical multi-oscillator structure, with the
