330-360 / 1000+ resultsresearch Natural variability and the influence of concurrent control values on the detection and interpretation of low-dose or weak endocrine toxicities.
Control variability makes it hard to confirm low-dose endocrine effects.
research Body dynamics, social meaning-making, and scale heterogeneity: re-considering contextualization cues and language as mixed-mode semiosis
Confinement in farrowing crates doesn't increase chronic stress in sows, but hair cortisol measurements may not reliably indicate stress due to hair growth variations.
research Sources of variation in hair cortisol in wild and captive non-human primates
Hair cortisol levels in primates are useful for stress assessment but vary by age, sex, species, and hair collection methods.
research Quantifying long-term stress in brown bears with the hair cortisol concentration: a biomarker that may be confounded by rapid changes in response to capture and handling
Hair cortisol levels in brown bears can be affected by both long-term and short-term stress.
research Temporary Relocation during Rest Periods: Relocation Stress and Other Factors Influence Hair Cortisol Concentrations in Horses
Moving horses to new places can increase their stress levels, as shown by higher stress hormone in their hair.
research WRKY transcription factors (TFs): Molecular switches to regulate drought, temperature, and salinity stresses in plants
WRKY transcription factors help plants manage stress and support growth.
research Skin diseases
Skin ages and changes due to sun, wind, and aging, causing dryness, thinning, and hair loss.
research SUN-439 Hypothalamic-Pituitary-Adrenal Axis Disruption from Unregulated Glucocorticoid Use: A Case Series
Unregulated glucocorticoid use can disrupt hormone balance and cause serious health issues.
research Menstrual Cycle Disturbances at Reproductive Age
Menstrual cycles can be irregular for women of childbearing age.
research Hair Cortisol: A Biomarker of Chronic Stress in Animals and its Association with Reproduction
High levels of cortisol in hair show long-term stress which can lower fertility in animals.
research Closing the AI generalization gap by adjusting for dermatology condition distribution differences across clinical settings
Adjusting AI training data for skin condition distribution improves accuracy across different clinical settings.
research Circadian rhythm sleep-wake disorders (CRSWDs): Linking circadian misalignment to adverse health outcomes.
Disruptions in sleep-wake cycles can cause health problems like mental, metabolic, and heart diseases, and cancer.
research THE FUNCTIONAL INTERRELATIONSHIP OF THE ANTERIOR PITUITARY AND THE ADRENAL CORTEX
The anterior pituitary controls adrenal cortex size and activity through ACTH.
research The Chronic Thermal Stress Model of Androgenetic Alopecia: A Unified Environmental–Vascular–Molecular Hypothesis
DHT increases scalp heat, causing hair loss.
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 The Chronic Thermal Stress Model of Androgenetic Alopecia: A Unified Environmental–Vascular–Molecular Hypothesis
DHT increases scalp heat, causing hair loss.
research Variación estacional del tricograma en residentes chilenos
Hair growth cycles in Chileans vary seasonally, with more hair resting in summer and growing in winter.
research Intermittent Chronic Telogen Effluvium
Emotional stress can trigger intermittent hair loss in chronic telogen effluvium, which may not improve with treatment if stress continues.
research Time Point 1 and 2 of Hair Cortisol
Wage increases and cash benefits reduced stress in early childhood educators.
research Influence of external factors on hair cortisol concentrations
External factors can significantly affect hair cortisol levels, so it's not always a reliable stress marker.
research Generalised Glucocorticoid Resistance
Mutations in the glucocorticoid receptor gene cause reduced sensitivity to glucocorticoids and may lead to poor response to treatment.
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 Collider bias undermines our understanding of COVID-19 disease risk and severity
Collider bias can distort our understanding of COVID-19 risk and severity.
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research Hair test reveals plasticity of human chronotype
HairTime can predict and adjust human sleep patterns using a hair sample.
research Factors influencing alopecia and hair cortisol in rhesus macaques (Macaca mulatta)
Captive management practices affect hair loss and stress in rhesus monkeys, with differences between facilities.
research Phenotypic heterogeneity in human genetic diseases: ultrasensitivity-mediated threshold effects as a unifying molecular mechanism
Different people show different symptoms for genetic diseases because of how sensitive their bodies are to small changes in important factors.
research Exposure to non-persistent pesticides and sexual maturation of Spanish adolescent males
Certain pesticides may delay sexual maturity in teenage boys.
research Economic disparities in parental hair cortisol are associated with externalizing behavior in children
Lower family income is linked to more stress in parents and more behavior problems in children.
