Longitudinal Assessment of Seasonal Impacts and Depression Associations on Circadian Rhythm Using Multimodal Wearable Sensing [PDF]
arXiv, 2023 Objective: This study aimed to explore the associations between depression severity and wearable-measured circadian rhythms, accounting for seasonal impacts and quantifying seasonal changes in circadian rhythms.Materials and Methods: Data used in this study came from a large longitudinal mobile health study. Depression severity (measured biweekly using

Circadian rhythm and cell population growth [PDF]
, 2010 Molecular circadian clocks, that are found in all nucleated cells of mammals, are known to dictate rhythms of approximately 24 hours (circa diem) to many physiological processes.

Parametric modeling of mechanical effects on circadian oscillators [PDF]
arXiv, 2023 Circadian rhythms are archetypical examples of nonlinear oscillations. While these oscillations are usually attributed to circuits of biochemical interactions among clock genes and proteins, recent experimental studies reveal that they are also affected by the cell's mechanical environment.

Circadian Rhythm Disruption Promotes Lung Tumorigenesis [PDF]
, 2018 Circadian rhythms are 24-hr oscillations that control a variety of biological processes in living systems, including two hallmarks of cancer, cell division and metabolism.

Continuous Circadian Phase Estimation Using Adaptive Notch Filter [PDF]
arXiv, 2018 Actigraphy has been widely used for the analysis of circadian rhythm. Current practice applies regression analysis to data from multiple days to estimate the circadian phase. This paper presents a filtering method for online processing of biometric data to estimate the circadian phase.

Unveiling Placental Development in Circadian Rhythm-Disrupted Mice: A Photo-acoustic Imaging Study on Unstained Tissue [PDF]
journal = {Placenta}, volume = {158}, pages = {57-61}, year =
{2024}Introduction: Circadian rhythm disruption has garnered significant attention for its adverse effects on human health, particularly in reproductive medicine and fetal well-being. Assessing pregnancy health often relies on diagnostic markers such as the labyrinth zone (LZ) proportion within the placenta.

Circadian Rhythms in Plants [PDF]
Cold Spring Harbor Perspectives in Biology, 2019 The circadian oscillator is a complex network of interconnected feedback loops that regulates a wide range of physiological processes. Indeed, variation in clock genes has been implicated in an array of plant environmental adaptations, including growth regulation, photoperiodic control of flowering, and responses to abiotic and biotic stress.

On the Excretion of Urinary 17-Hydroxycorticosteroids (17-OHCS) in Antarctic Region [PDF]
, 1976 In the study of the effect of chilliness and the tendency of cryodomestication, the urinary output of 17-Hydroxycorticosteroids (17-OHCS) was used, and its circadian rhythm was investigated.

Genetics of Circadian Rhythms [PDF]
Sleep Medicine Clinics, 2015 Nearly all organisms exhibit time-dependent behavior and physiology across a 24-hour day known as circadian rhythms. These outputs are manifestations of endogenous cyclic gene expression patterns driven by the activity of a core transcription/translation feedback loop.
