Extended gate field-effect-transistor for sensing cortisol stress hormone

Mihai Adrian Ionescu, Hoël Maxime Guérin, Junrui Zhang, Sadegh Kamaei Bahmaei, Luca Capua, Shokoofeh Sheibani

Cortisol is a hormone released in response to stress and is a major glucocorticoid produced by adrenal glands. Here, we report a wearable sensory electronic chip using label-free detection, based on a platinum/graphene aptamer extended gate field effect tr ...

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

Vincent Kaufmann, Guillaume Simon Joseph Drevon

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 ...

Multi-omics reveals abundant mitochondrial genomic and circadian expression variation in the Drosophila Genetic Reference Panel

Maria Litovchenko

Modern biology rapidly generates a wealth of data,which can only be analysed computationally.Despite the variety of available data types,most of them aim to provide an answer to one question: how does genotypic diversity translates into phenotypes? This qu ...

In pancreatic islets from type 2 diabetes patients, the dampened circadian oscillators lead to reduced insulin and glucagon exocytosis

Daniel Sage

Circadian clocks operative in pancreatic islets participate in the regulation of insulin secretion in humans and, if compromised, in the development of type 2 diabetes (T2D) in rodents. Here we demonstrate that human islet alpha- and beta-cells that bear a ...

Circadian rhythms and proteomics: It's all about posttranslational modifications!

Daniel Alain Dominique Marie Mauvoisin

The circadian clock is a molecular endogenous timekeeping system and allows organisms to adjust their physiology and behavior to the geophysical time. Organized hierarchically, the master clock in the suprachiasmatic nuclei, coordinates peripheral clocks, ...

Tissue-specific circadian transcriptional regulation

Jake Yeung

Circadian rhythms in physiology and behavior evolved to resonate with daily cycles in the external environment. In mammals, organs orchestrate temporal physiology over the 24-hour day, which requires extensive gene expression rhythms targeted to the right ...

Sleep-wake-driven and circadian contributions to daily rhythms in gene expression and chromatin accessibility in the murine cortex

Felix Naef, Jake Yeung, Maxime Jan

The timing and duration of sleep results from the interaction between a homeostatic sleep-wake-driven process and a periodic circadian process, and involves changes in gene regulation and expression. Unraveling the contributions of both processes and their ...

The Mouse Microbiome Is Required for Sex-Specific Diurnal Rhythms of Gene Expression and Metabolism

Felix Naef, Cédric Gobet, Jake Yeung, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

The circadian clock and associated feeding rhythms have a profound impact on metabolism and the gut microbiome. To what extent microbiota reciprocally affect daily rhythms of physiology in the host remains elusive. Here, we analyzed transcriptome and metab ...

Low-dimensional dynamics of two coupled biological oscillators

Felix Naef, Eric Paquet, Colas Noé Droin

The circadian clock and the cell cycle are two biological oscillatory processes that coexist within individual cells. These two oscillators were found to interact, which can lead to their synchronization. Here, we develop a method to identify a low-dimensi ...
