Uncovering personalized glucose responses and circadian rhythms from multiple wearable biosensors with Bayesian dynamical modeling

Wearable biosensors and smartphone applications can measure physiological variables over multiple days in free-living conditions. We measure food and drink ingestion, glucose dynamics, physical activity, heart rate (HR), and heart rate variability (HRV) in ...

Dealing with Daily Rhythms: Families’ Strategies to Tackle Chronic Time Pressure

Vincent Kaufmann, Guillaume Simon Joseph Drevon, Philippe Gerber

As suggested by the conservation of resources theory, in contemporary societies time is considered as a limited resource in the same way as money and energy. In the current paper, a novel daily rhythm approach related to motility is presented, in order to ...

A new promoter element associated with daily time keeping in Drosophila

Felix Naef, Eric Paquet

Circadian clocks are autonomous daily timekeeping mechanisms that allow organisms to adapt to environmental rhythms as well as temporally organize biological functions. Clock-controlled timekeeping involves extensive regulation of rhythmic gene expression. ...

Guidelines for Genome-Scale Analysis of Biological Rhythms

Felix Naef, Frédéric Bruno Martin Gachon, Alaaddin Bulak Arpat, Han Wang, Zheng Chen, Xiaodong Li

Genome biology approaches have made enormous contributions to our understanding of biological rhythms, particularly in identifying outputs of the clock, including RNAs, proteins, and metabolites, whose abundance oscillates throughout the day. These methods ...

Modelling 'non-visual' effects of daylighting in a residential environment

Marilyne Andersen, Sharon Jane Gochenour, Steven W. Lockley

The importance of light not only as a therapeutic tool but as an essential element of healthy living has been highlighted by the recent discovery of a specialized photoreceptor in the eye responsible for synchronizing our internal circadian pacemaker. This ...

The Circadian Clock Coordinates Ribosome Biogenesis

Felix Naef, Laura Symul, Frédéric Bruno Martin Gachon, Florian Atger, Celine Jouffe

Biological rhythms play a fundamental role in the physiology and behavior of most living organisms. Rhythmic circadian expression of clock-controlled genes is orchestrated by a molecular clock that relies on interconnected negative feedback loops of transc ...

Simulation-based evaluation of non-visual responses to daylight: proof-of-concept study of healthcare re-design

Marilyne Andersen, María Lovísa Ámundadóttir, Steven W. Lockley

The discovery of a novel non-rod, non-cone photoreceptor in the human eye that mediates a number of effects on the brain has sparked a growing interest in incorporating these non-visual effects of light into the design process of buildings. Appropriately–t ...

Light and chronobiology: Implications for health and disease

Mirjam Münch

Environmental light synchronizes the primary mammalian biological clock in the suprachiasmatic nuclei, as well as many peripheral clocks in tissues and cells, to the solar 24-hour day. Light is the strongest synchronizing agent (zeitgeber) for the circadia ...

Metabolic response of the cerebral cortex following gentle sleep deprivation and modafinil administration

Pierre Magistretti, Jean-Marie Petit, Christophe Kopp

Objectives: The main energy reserve of the brain is glycogen, which is almost exclusively localized in astrocytes. We previously reported that cerebral expression of certain genes related to glycogen metabolism changed following instrumental sleep deprivat ...

Stochastic phase oscillator models for circadian clocks

Felix Naef, Jacques Rougemont

Periodic environments like we experience on the surface of planet earth lead living organisms to evolve molecular anticipation devices known a circadian clocks. The word circadian refers to the period of these oscillations which last about (circa) one day ...
