Circadian Rhythm, Lifestyle and Health: A Narrative Review

open access: yesIranian Journal of Public Health, 2018
Background: The circadian rhythm regulation plays a crucial role in people`s healthy lives affected by factors consisting of cosmic events related to the universe and earth, environmental factors (light, night and day duration, seasons) and lifestyles ...

What is the Effect of Social Rhythm Disrupting Events on Mood in Individuals with Bipolar Disorder? [PDF]

open access: yes, 2013
The social zeitgeber hypothesis suggests that life events have the capacity to lead to the onset of affective episodes in those vulnerable to bipolar disorder via biological and social rhythm disruption. However, few studies have systematically evaluated

Polymorphisms in the circadian expressed genes PER3 and ARNTL2 are associated with diurnal preference and GNβ3 with sleep measures [PDF]

open access: yes, 2014
Sleep and circadian rhythms are intrinsically linked, with several sleep traits, including sleep timing and duration, influenced by both sleep homeostasis and the circadian phase.

Dual‐Channel Interdigitated Aptamer‐Based Sensors for Rapid Small‐Molecule Detection in Biofluids

open access: yesAngewandte Chemie International Edition, EarlyView.
An electrochemical aptamer sensing chip employs dual interdigitated electrodes and selective self‐assembled monolayer removal to convert small‐molecule recognition into robust “signal‐off/on” responses. This dual‐channel signal conversion minimizes background noise and accelerates probe diffusion, enabling rapid (as fast as 5–30 min), low‐volume ...

The Neurobiology of Circadian Rhythms

open access: yesPsychiatric Clinics of North America, 2015
There is a growing recognition that the coordinated timing of behavioral, physiologic, and metabolic circadian rhythms is a requirement for a healthy body and mind. In mammals, the primary circadian oscillator is the hypothalamic suprachiasmatic nucleus (SCN), which is responsible for circadian coordination throughout the organism. Temporal homeostasis

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

A Mouse Model of Depression‐Tumor Multimorbidity Reveals the Mechanism of Tumor Growth Accelerated by Depression

open access: yesAnimal Research and One Health, EarlyView.
Depression accelerates tumor growth by dysregulation of tumor immune microenvironment. (A) Modeling methods: Subcutaneous tumor models were established under chronic unpredictable mild stress conditions, including cold swimming, physical restraint, and food/water deprivation, leading to increased tumor growth.

Novel mechanisms operating in the central pacemaker and in the light-synchronization pathway of Drosophila’s circadian clock

open access: yes, 2011
PhDMost organisms display circadian rhythms of approximately 24 hours in many aspects of their physiology and behaviour. The synchronization between their internal rhythm and the environmental light-dark cycles is essential for an organism’s survival ...

The impact of sleep pressure, circadian phase and an ADA-polymorphism on working memory: a behavioral, electrophysiological, neuroimaging approach [PDF]

open access: yes, 2015
The need for sleep, the so-called sleep pressure, increases continuously during wakefulness and decreases during sleep again, in particular during intense deep sleep (Borbely, 1982).
