Phenotypic Variability in Slow‐Wave Sleep in Depression: Associations With Clinical Profiles and Disorder Severity

Journal of Sleep Research, EarlyView.
ABSTRACT Slow‐wave sleep (SWS; stage N3) is often reported as reduced in depression, yet variability across depressive phenotypes remains poorly characterised. This study aimed to determine whether N3 architecture—proportion, duration, and latency—identifies clinically distinct profiles in major depressive episode (MDE).

Effect of Five-Consecutive-Day Exposure to an Anxiogenic Stressor on Sleep-Wake Activity in Rats [PDF]

, 2013
Repeated exposure to an anxiogenic stressor (AS) is a known environmental factor for the development of depression, yet the progression of sleep-wake (S-W) changes associated with the onset of AS-induced depression (ASID) is not completely understood ...

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Chronobiology Revisited in Psychiatric Disorders: From a Translational Perspective [PDF]

Psychiatry Investigation, 2019
Several lines of evidence support a relationship between circadian disruption in the onset, course, and maintenance of mental disorders. Despite the study of circadian phenotypes promising a decent understanding of the pathophysiologic or etiologic mechanisms of psychiatric entities, several questions still need to be addressed.

p75NTR Promotes Circadian‐Driven Mineralization During Tooth Development via CK2/PER2 Pathway

Cell Proliferation, Volume 59, Issue 5, May 2026.
The diagram illustrates how the circadian rhythm regulates the p75NTR‐CK2‐PER2 axis, driving rhythmic biomineralisation during tooth development. ABSTRACT Circadian rhythm is an essential biological process that synchronises physiological activities with environmental light/dark cycles.
