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 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 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 The Intersection of Sleep and Hair Loss: A Systematic Review
Poor sleep may lead to hair loss, and hair loss may affect sleep.
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 Attention to Innate Circadian Rhythm and the Impact of Its Disruption on Diabetes
Disrupting natural body clocks increases the risk of developing type 2 diabetes.
research Four days of simulated shift work reduces insulin sensitivity in humans
Working night shifts for four days can lower the body's ability to use insulin, which may increase the risk of type 2 diabetes.
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 Epidemiological study of prostate cancer (EPICAP): a population-based case–control study in France
Circadian rhythm disruption, chronic inflammation, hormones, metabolism, and genetics may increase prostate cancer risk.
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 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 Causal Relationship Between Sleep Characteristics and Alopecia Areata and Other Non-Scarring Alopecia: A Two-Sample Bidirectional Mendelian Randomization Analysis
Insomnia may increase alopecia areata risk, but more research is needed.
research Cognitive testing of a survey instrument for self-assessed menstrual cycle characteristics and androgen excess
The survey helps identify menstrual irregularities and excess male hormones, aiming to detect conditions like Polycystic Ovary Syndrome.
research The Ecology of Human Sleep (EcoSleep) Project: Protocol for a longitudinal cohort repeated-measurement-burst study to assess the relationship between sleep determinants and sleep outcomes under real-world conditions across time of year
The study aims to understand how mood, physical activity, light exposure, and seasonal changes affect sleep patterns.
research A hair growth questionnaire for use in the evaluation of therapeutic effects in men
The questionnaire effectively measures men's perceived hair growth and can distinguish between different treatments and dosages.
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 Association between serum melatonin and skin aging in an urban population of Mongolia
Lower melatonin levels are linked to more skin aging.
research Dysmorphic Concern Questionnaire: Greek Translation, Validation and Psychometric Properties
The Greek DCQ is a reliable and valid tool for assessing dysmorphic concern.
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 test reveals plasticity of human chronotype
HairTime can predict and adjust human sleep patterns using a hair sample.
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 Pubertal development in early adolescent girls: Relationships to mood, energy, restlessness, and certainty about self.
Early puberty in girls leads to intense moods, restlessness, and greater self-certainty.
research Psychometric performance of EQ-5D-5L and SF-6DV2 in measuring health status of populations in Chinese university staff and students
Both EQ-5D-5L and SF-6DV2 are valid for measuring health but can't be used interchangeably.
research The Polycystic Ovary Syndrome Health-Related Quality-of-Life Questionnaire: Confirmatory Factor Analysis
