research Hormones and clocks: do they disrupt the locks? Fluctuating estrogen levels during menopausal transition may influence clock genes and trigger chronic telogen effluvium
Changing estrogen levels during menopause might affect genes related to body rhythms and cause increased hair loss.
research Effects of bright light exposure during daytime on peripheral clock gene expression in humans
Bright light during the day doesn't change most human clock genes but may slightly increase Rev-erb-ß.
research Investigating the role of obesity, circadian disturbances and lifestyle factors in people with schizophrenia and bipolar disorder: Study protocol for the SOMBER trial
The trial aims to understand how obesity and lifestyle affect circadian rhythms in people with schizophrenia and bipolar disorder.
research Low temperature abolishes human cellular circadian rhythm through Hopf bifurcation
Cold temperatures can stop human cell circadian rhythms, but warming restores them.
research Stem cells and the circadian clock
The circadian clock influences the behavior and regeneration of stem cells in the body.
research Human long-term deregulated circadian rhythm alters regenerative properties of skin and hair precursor cells
Disrupted sleep patterns can harm skin and hair cell renewal, but melatonin might help.
research Fail-tests of DNA methylation clocks, and development of a noise barometer for measuring epigenetic pressure of aging and disease
Elastic Net DNA methylation clocks are inaccurate for predicting age and health status; a "noise barometer" may better indicate aging and disease.
research Analysis of epigenetic clocks links yoga, sleep, education, reduced meat intake, coffee, and a SOCS2 gene variant to slower epigenetic aging
research Biologic Rhythms Derived from Siberian Mammoths' Hairs
Mammoth hair grew faster than human hair and showed seasonal changes in growth and mineral content.
research The clock within
The circadian clock in skin cells controls their growth and rest cycles.
research Circadian rhythms on skin function of hairless rats: light and thermic influences
Light and temperature affect the daily skin function rhythms in hairless rats, with temperature influencing water loss but not skin hydration.
research Clock genes, hair growth and aging
Circadian clock genes are important for hair growth and may affect aging-related hair loss and graying.
research Molecular Basis of Maintaining Circannual Rhythm in the Skin of Cashmere Goat
Goat skin changes with the seasons due to genes affected by daylight and hormones.
research Molecular Basis of Maintaining Circannual Rhythm in the Skin of Cashmere Goat
Goat skin adapts to seasonal changes through genes that respond to daylight length, affecting hormone levels and potentially making skin cells light-sensitive.
research The Opioid Receptor Influences Circadian Rhythms in Human Keratinocytes through the β-Arrestin Pathway
Delta-opioid receptors affect skin cell circadian rhythms, possibly impacting wound healing and cancer.
research Association between sleep patterns, circadian rhythms, and hair loss in young adults
Irregular sleep and disrupted body clocks can lead to more hair loss in young adults.
research Estimation of biological heart age using cardiovascular magnetic resonance radiomics
Obesity and lifestyle strongly affect heart aging.
research The hair eclipse phenomenon: sharpening the focus on the hair cycle chronobiology
Hair growth and shedding are linked and can be disrupted, causing a delay known as the hair eclipse phenomenon, which is common in certain hair conditions and could lead to new treatments.
research An integrative view of mammalian seasonal neuroendocrinology
The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.
research Association of 1-Year Blood Pressure Variability With Long-term Mortality Among Adults With Coronary Artery Disease
Higher variability in systolic blood pressure increases long-term mortality risk in coronary artery disease patients.
research When the Circadian Clock Meets the Melanin Pigmentary System
Silencing certain circadian clock genes increases skin pigmentation.
research Recent advances in the molecular mechanisms determining tissue sensitivity to glucocorticoids: novel mutations, circadian rhythm and ligand-induced repression of the human glucocorticoid receptor
New findings explain how genetic changes, body clocks, and certain molecules affect tissue response to stress hormones.
research Age-related changes in endogenous glucocorticoids, gonadal steroids, endocannabinoids and their ratios in plasma and hair from the male C57BL/6 mice
Male C57BL/6 mice show age-related fluctuations in certain hormones and their ratios in both blood and hair.
research The Peripheral Clock Regulates Human Pigmentation
Certain genes control the color of human hair by affecting pigment production.
research Integrative study of gene expression and protein complexes
Cell processes depend on time-of-day and protein complex flexibility for skin health.
research Local circadian clock gates cell cycle progression of transient amplifying cells during regenerative hair cycling
Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
research The effect of sleep extension on metabolic and androgen parameters of healthy women with habitual short sleep duration: Pilot study
Increasing sleep by 41 minutes daily for a month showed no significant changes in metabolism or hormone levels in healthy women.
research Improving stable isotopic interpretations made from human hair through reduction of growth cycle error
The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.
research Cyclical dermal micro-niche switching governs the morphological infradian rhythm of mouse zigzag hair
Mouse zigzag hair bends form due to a 3-day cycle of changes in hair progenitors and their environment.
