Discomfort Glare from Daylighting: Influence of Culture on Discomfort Glare Perception

Jan Wienold, Clotilde Marie A Pierson, Magali Bodart

In a context where lighting standards are developed based on glare indices, no study has ever investigated that these indices could be used analogously for subjects having different cultures and living in different climates. The wide variability existing b ...

High light intensity mediates a shift from allochthonous to autochthonous carbon use in phototrophic stream biofilms

Tom Ian Battin, Amber Joy Ulseth

Changes in the riparian vegetation along stream channels, diurnal light availability, and longitudinal fluctuations in the local light regime in streams influence primary production and carbon (C) cycling in benthic stream biofilms. To investigate the infl ...

Nuclear Proteomics Uncovers Diurnal Regulatory Landscapes in Mouse Liver

Felix Naef, Loïc Dayon, Frédéric Bruno Martin Gachon, Martin Kussmann, Daniel Alain Dominique Marie Mauvoisin, Jingkui Wang, Florian Atger, Federico Sizzano

Diurnal oscillations of gene expression controlled by the circadian clock and its connected feeding rhythm enable organisms to coordinate their physiologies with daily environmental cycles. While available techniques yielded crucial insights into regulatio ...

Glucose Homeostasis: Regulation by Peripheral Circadian Clocks in Rodents and Humans

Frédéric Bruno Martin Gachon

Most organisms, including humans, have developed an intrinsic system of circadian oscillators, allowing the anticipation of events related to the rotation of Earth around its own axis. The mammalian circadian timing system orchestrates nearly all aspects o ...

Bright Light Delights: Effects of Daily Light Exposure on Emotions, Rest-activity Cycles, Sleep and Melatonin Secretion in Severely Demented Patients

Jean-Louis Scartezzini

Objective: We tested whether the effects of a dynamic lighting system are superior to conventional lighting on emotions, agitation behaviour, quality of life, melatonin secretion and circadian restactivity cycles in severely demented patients. As a compari ...

Lipidomics reveals diurnal lipid oscillations in human skeletal muscle persisting in cellular myotubes cultured in vitro

Jonathan Paz Montoya, Marc Moniatte, Frédéric Bruno Martin Gachon, Howard Riezman, Benjamin Dieter Weger

Circadian clocks play an important role in lipid homeostasis, with impact on various metabolic diseases. Due to the central role of skeletal muscle in whole-body metabolism, we aimed at studying muscle lipid profiles in a temporal manner. Moreover, it has ...

Transcriptional regulatory logic of the diurnal cycle in the mouse liver

Matteo Dal Peraro, Bart Deplancke, Felix Naef, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Sunil Kumar Raghav, Nouria Hernandez, Irina Krier, Guillaume Rey, Alexandra Styliani Kalantzi, Jonathan Aryeh Sobel

Many organisms exhibit temporal rhythms in gene expression that propel diurnal cycles in physiology. In the liver of mammals, these rhythms are controlled by transcription-translation feedback loops of the core circadian clock and by feeding-fasting cycles ...

Stem cells and the circadian clock

Benjamin Dieter Weger, Meltem Weger

The circadian timing system is a complex biological network of interacting circadian clocks that regulates 24 h rhythms of behavioral and physiological processes. One intriguing observation is that stem cell homeostasis is subject to circadian clock regula ...

Discomfort glare perception in daylighting: influencing factors

Jan Wienold, Clotilde Marie A Pierson

The mechanism behind the discomfort glare phenomenon, the kind of glare provoking an irritating or distracting effect, is not well understood. Since some of the factors influencing this phenomenon are still unknown, no current indices can properly explain ...

Diurnal Oscillations in Liver Mass and Cell Size Accompany Ribosome Assembly Cycles

Frédéric Bruno Martin Gachon, Daniel Alain Dominique Marie Mauvoisin, Jingkui Wang

The liver plays a pivotal role in metabolism and xenobiotic detoxification, processes that must be particularly efficient when animals are active and feed. A major question is how the liver adapts to these diurnal changes in physiology. Here, we show that, ...
