Circadian rhythmicity of amyloid‐beta‐related molecules is disrupted in the choroid plexus of a female Alzheimer's disease mouse model
Sign Up to like & getrecommendations! Published in 2022 at "Journal of Neuroscience Research"
DOI: 10.1002/jnr.25164
Abstract: The choroid plexus (CP) is part of the blood‐cerebrospinal fluid barrier (BCSFB) and was recently described as an important component of the circadian clock system. It is the principal source of cerebrospinal fluid (CSF) and… read more here.

DOI: 10.1007/s12020-020-02273-w
Abstract: Purpose In previous studies, associations between breast-milk cortisol levels obtained on one occasion and infant neurodevelopment were demonstrated. However, more recent evidence indicates that breast-milk cortisol and cortisone concentrations follow the diurnal rhythm of maternal… read more here.

DOI: 10.1016/j.cois.2018.06.002
Abstract: Insects utilize an open circulatory system to transport nutrients, waste, hormones and immune factors throughout the hemocoel. The primary organ that drives hemolymph circulation is the dorsal vessel, which is a muscular tube that traverses… read more here.

Intrinsic Rhythmicity Predicts Synchronization-Continuation Entrainment Performance
Sign Up to like & getrecommendations! Published in 2018 at "Scientific Reports"
DOI: 10.1038/s41598-018-29267-z
Abstract: Rhythmic entrainment—defined as a stable temporal relationship between external periodic signals and endogenous rhythmic processes—allows individuals to coordinate with environmental rhythms. However, the impact of inter-individual differences on entrainment processes as a function of the… read more here.

DOI: 10.1038/s41598-018-32778-4
Abstract: Studies of locomotor activity in Svalbard reindeer reported the temporary absence of diel rhythms under Arctic photic conditions. However, using Lomb-Scargle periodogram analyses with high statistical power we found diel or circadian rhythmicity throughout the… read more here.

DOI: 10.1038/s41598-024-54490-2
Abstract: The labor is a physiological event considered to have its own circadian (diurnal) rhythm, but some of the data remain conflicting, especially for preterm births. In this retrospective study, we analyzed the circadian trends of… read more here.

DOI: 10.1055/a-2078-4905
Abstract: Circadian rhythms are biological oscillations, that perpetuate themselves even in the absence of “zeitgebers” (external time cues), with a period of approximately 24 hours. The master pacemaker is the suprachiasmatic nucleus (SCN) of the hypothalamus. The… read more here.
