A Touch Enabled Hemodynamic and Metabolic Monitor
Advanced Science, EarlyView.This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.

Protein sequestration versus Hill-type repression in circadian clock models [PDF]
arXiv, 2016 Circadian (~24hr) clocks are self-sustained endogenous oscillators with which organisms keep track of daily and seasonal time. Circadian clocks frequently rely on interlocked transcriptional- translational feedback loops to generate rhythms that are robust against intrinsic and extrinsic perturbations.

Functional independence of circadian clocks that regulate plant gene expression [PDF]
Background: Circadian clocks regulate the gene expression, metabolism and behaviour of most eukaryotes, controlling an orderly succession of physiological processes that are synchronised with the environmental day/night cycle.

The influence of biological rhythms on host–parasite interactions [PDF]
, 2015 Biological rhythms, from circadian control of cellular processes to annual cycles in life history, are a main structural element of biology. Biological rhythms are considered adaptive because they enable organisms to partition activities to cope with ...

Synchrony and desynchrony in circadian clocks: impacts on learning and memory
Learning & memory (Cold Spring Harbor, N.Y.), 2015 Circadian clocks evolved under conditions of environmental variation, primarily alternating light dark cycles, to enable organisms to anticipate daily environmental events and coordinate metabolic, physiological, and behavioral activities.

DNA damage and the circadian clock [PDF]
BioDiscovery, 2014 The role of the circadian clock has already been demonstrated for virtually all physiological processes, but it was only recently shown that cells were more sensitive to DNA damage at specific times of the day; that the peak of synthesis of mRNA and proteins of genes coding for products involved directly or indirectly in DNA repair was differentially ...

Advanced Science, EarlyView.This study identifies a class of amino acid‐sensing neurons, APCCRH neurons, which regulate BAT thermogenesis. Leucine deficiency alters intrinsic excitability through GCN2 signaling pathway, activating APCCRH neurons, which in turn regulate BAT thermogenesis via projections to the lateral hypothalamus.

Influence of photic perturbations on circadian rhythms [PDF]
arXiv, 2019 The circadian clock is the molecular mechanism responsible for the adaptation to daily rhythms in living organisms. Oscillations and fluctuations in environmental conditions regulate the circadian clock through signaling pathways. We study the response to continuous photic perturbations in a minimal molecular network model of the circadian clock ...

Mammalian Molecular Clocks [PDF]
, 2010 As a consequence of the Earth's rotation, almost all organisms experience day and night cycles within a 24-hr period. To adapt and synchronize biological rhythms to external daily cycles, organisms have evolved an internal time-keeping system. In mammals,

Advanced Science, EarlyView.This study proposes a two‐step biological strategy to synergistically enhance the three stages of anaerobic digestion, ultimately eliminating the extreme ammonia inhibition and breaking through the inefficiency bottleneck of conventional biotechnology.
