Diurnal differences in urine flow in healthy young men in a light-controlled environment: a randomized crossover design
BackgroundOlder men often experience nocturnal urination difficulties, reflected by diurnal differences in maximum urine flow (Qmax). Since lower...

Artificial light at night suppresses the day-night cardiovascular variability: evidence from humans and rats
Artificial light at night (ALAN) affects most of the population. Through the retinohypothalamic tract, ALAN modulates the activity of the central...

Diurnal modulation of subthalamic beta oscillatory power in Parkinson’s disease patients during deep brain stimulation
Beta-band activity in the subthalamic local field potential (LFP) is correlated with Parkinson’s disease (PD) symptom severity and is the therapeutic...

Variability of corticospinal and spinal reflex excitability for the ankle dorsiflexor tibialis anterior across repeated measurements in people with and without incomplete spinal cord injury
To adequately evaluate the corticospinal and spinal plasticity in health and disease, it is essential to understand whether and to what extent the...

Evaluation of diurnal and postural intracranial pressure employing telemetric monitoring in idiopathic intracranial hypertension
ObjectivesIntracranial pressure (ICP) has been thought to vary diurnally. This study evaluates diurnal ICP measurements and quantifies changes in ICP...

Diurnal variations in muscle and liver glycogen differ depending on the timing of exercise
It has been suggested that glycogen functions not only in carbohydrate energy storage, but also as molecular sensors capable of activating lipolysis....

Diurnal changes in perineuronal nets and parvalbumin neurons in the rat medial prefrontal cortex
Perineuronal nets (PNNs) surrounding fast-spiking, parvalbumin (PV) interneurons provide excitatory:inhibitory balance, which is impaired in several...

Effects of time of the day at sampling on CSF and plasma levels of Alzheimer’ disease biomarkers
BackgroundStudies suggest that cerebrospinal fluid (CSF) levels of amyloid-β (Aβ)42 and Aβ40 present a circadian rhythm. However sustained sampling...
