Circadian cuisine in synchronizing holistic nutrition and biological rhythms

open access: yesWorld Nutrition
Chronobiology 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 medullary hub for controlling REM sleep and pontine waves

open access: yesNature Communications, 2023
Rapid-eye-movement (REM) sleep is a distinct behavioral state associated with vivid dreaming and memory processing. Phasic bursts of electrical activity, measurable as spike-like pontine (P)-waves, are a hallmark of REM sleep implicated in memory ...

Differential impact in young and older individuals of blue-enriched white light on circadian physiology and alertness during sustained wakefulness

open access: yesScientific 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

A circadian clock regulates efflux by the blood-brain barrier in mice and human cells

open access: yesNature 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.

Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Light color importance for circadian entrainment in a diurnal (Octodon degus) and a nocturnal (Rattus norvegicus) rodent

open access: yesScientific 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.

Bile acid metabolism and sleep: Mechanistic interplay and clinical implications of the gut–liver–brain axis

open access: yesSleep Research, EarlyView.
Abstract The bidirectional interplay between sleep and metabolic homeostasis is fundamental to physiological health. While the roles of glucose and lipid metabolism in sleep regulation have been extensively characterized, bile acids (BAs), which are traditionally viewed as digestive surfactants, are emerging as critical metabolic messengers with ...

Weight loss in conservative treatment of obesity in women is associated with physical activity and circadian phenotype: a longitudinal observational study

open access: yesBioPsychoSocial Medicine, 2019
Introduction The study investigates the association between circadian phenotype (CP), its stability (interdaily stability - IS) and physical activity (PA) in a weight loss (WL) programme.

Chronobiology

open access: yes, 2009
Chronobiology is the study of biological processes with respect to time, specifically concerning the four environmental rhythms, namely tide, day, moon and season. It is not concerned with linear time-dependent processes such as aging.

Daily Rhythms of Sex Pheromone Emission and Courtship Behaviour in the Neotropical Brown Stink Bug Euschistus heros

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.
