research Thyroxine Differentially Modulates the Peripheral Clock: Lessons from the Human Hair Follicle
Thyroxine can adjust the body's peripheral clock, potentially helping treat clock-related diseases.
research Peripheral Skin Temperature and Circadian Biological Clock in Shift Nurses after a Day off
Shift nurses show altered body temperature and stress hormone levels, suggesting their body clocks adjust to irregular schedules.
research Diurnal Preference Predicts Phase Differences in Expression of Human Peripheral Circadian Clock Genes
An individual's morning or evening preference can predict changes in their body clock gene expression.
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 Noninvasive method for assessing the human circadian clock using hair follicle cells
Scientists found a new, less invasive way to study body clocks using hair cells, which shows shift workers' body clocks don't match their lifestyles.
research A Meeting of Two Chronobiological Systems: Circadian Proteins Period1 and BMAL1 Modulate the Human Hair Cycle Clock
BMAL1 and Period1 genes can influence human hair growth.
research Estimation methods for human circadian phase by use of peripheral tissues
New method uses hair follicle cells to estimate human body clock phase, potentially improving sleep disorder diagnosis.
research Disturbance of the Circadian System in Shift Work and Its Health Impact
Shift work disrupts the body's natural clock, leading to health problems.
research Molecular insights into chronotype and time-of-day effects on decision-making
People's decision-making can be influenced by their internal biological clocks, as shown by gene expression, not just self-reported preferences for morning or evening.
research A simple method using ex vivo culture of hair follicle tissue to investigate intrinsic circadian characteristics in humans
Researchers developed a way to study human body clocks using hair tissue, which works similarly in both healthy and dementia patients.
research Investigation of a non-invasive method of assessing the equine circadian clock using hair follicle cells
RNA from horse hair follicles can track circadian rhythms non-invasively.
research When the Circadian Clock Meets the Melanin Pigmentary System
Silencing certain circadian clock genes increases skin pigmentation.
research Rhythmic expression of circadian clock genes in human leukocytes and beard hair follicle cells
Human leukocytes and beard hair follicle cells have internal daily clocks, and PER1 and PER3 genes may indicate individual circadian rhythms.
research Hair Follicles as a Critical Model for Monitoring the Circadian Clock
Hair follicles could be used to noninvasively monitor our body's internal clock and help identify risks for related diseases.
research Overview of the Circadian Clock in the Hair Follicle Cycle
The circadian clock plays a key role in hair growth and its disruption can affect hair regeneration.
research Orientation of Multi-Hair Follicles in Nonbald Men: Perpendicular Versus Parallel
Most men's multi-hair follicles naturally stand perpendicular to a line from the top of their head, which is important for natural-looking hair transplants.
research Orientation of Multi-Hair Follicles in Nonbald Men
Most nonbald men's multi-hair follicles are naturally positioned perpendicular to a line from the scalp's crown, which is important for natural-looking hair transplants.
research The Circadian Clock in Skin
The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.
research Circadian clock-mediated control of stem cell division and differentiation: beyond night and day
The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.
research Circadian clocks: from stem cells to tissue homeostasis and regeneration
Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.
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 Stem cells and the circadian clock
The circadian clock influences the behavior and regeneration of stem cells in the body.
research An out-of-lab trial: a case example for the effect of intensive exercise on rhythms of human clock gene expression
Intense exercise at night can delay the body's internal clock gene expression by 2 to 4 hours.
research The clock within
The circadian clock in skin cells controls their growth and rest cycles.
research The effect of night shift work on the expression of clock genes in beard hair follicle cells
Night shift work disrupts the body's natural clock genes.
research Timing of expression of the core clock gene Bmal1 influences its effects on aging and survival
The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.
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 Melatonin membrane receptors in peripheral tissues: Distribution and functions
Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.
research Melatonin Receptors and Their Role in Human Diseases
Melatonin receptors, found in many body parts, can help treat various diseases like depression and diabetes due to their effects on inflammation, tumor progression, sleep disorders, and body mass regulation.
