Chronobiology of Epilepsy [PDF]
Nature Precedings, 2008 AbstractA fine balance between neuronal excitation and inhibition governs the physiological state of the brain. It has been hypothesized that when this balance is lost as a result of excessive excitation or reduced inhibition, pathological states such as epilepsy emerge. Decades of investigation have shown this to be true in vitro.

Scientific Reports, 2017 We tested the effect of different lights as a countermeasure against sleep-loss decrements in alertness, melatonin and cortisol profile, skin temperature and wrist motor activity in healthy young and older volunteers under extendend wakefulness. 26 young

Circadian cuisine in synchronizing holistic nutrition and biological rhythms
World NutritionChronobiology is an emerging area of research exploring the complex relationship between circadian rhythms and nutrition. This review discusses the interplay of chronobiology and overall nutrition. In simpler terms, the time we eat affects our nutrition

A circadian clock regulates efflux by the blood-brain barrier in mice and human cells
Nature Communications, 2021 The blood-brain barrier is critical for neural function. Here, the authors show that efflux of xenobiotics through the BBB follows a circadian rhythm in mice and human cells.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Neuronal Responses to Short Wavelength Light Deficiency in the Rat Subcortical Visual System
Frontiers in Neuroscience, 2021 The amount and spectral composition of light changes considerably during the day, with dawn and dusk being the most crucial moments when light is within the mesopic range and short wavelength enriched.

Cancer Science, EarlyView.In this study we investigate the role of the core circadian gene BMAL1 in regulating mechanisms within non‐small cell lung cancer cells, revealing that circadian rhythm disruption may represent another significant factor triggering apoptosis. ABSTRACT The circadian clock is a crucial regulator of mammalian physiology, controlling daily oscillations in ...

Scientific Reports, 2017 The central circadian pacemaker (Suprachiasmatic Nuclei, SCN) maintains the phase relationship with the external world thanks to the light/dark cycle. Light intensity, spectra, and timing are important for SCN synchronisation.

Journal of Diabetes Investigation, EarlyView.The frequency and severity of hypoglycemia peak before lunch and its nadir is 17:30 PM and increases through the post‐discharge days. ABSTRACT Introduction Insulin improves clinical outcomes in hospitalized patients; however, hypoglycemia hinders discharge transition in patients with insulin‐treated diabetes.
