research Evidence for various calcium sites in human hair shaft revealed by sub-micrometer X-ray fluorescence
The research found two types of calcium in human hair, one that varies among individuals and another that is consistent across people.
research SHORT-TERM DIABETES IN THE BRAIN: EFFECTS ON NEUROACTIVE STEROIDS, CHOLESTEROL HOMEOSTASIS, AND MITOCHONDRIAL FUNCTIONALITY
Short-term diabetes can cause changes in brain steroids, cholesterol balance, and mitochondrial function.
research Effects of neonatal and adolescent neuroactive steroid manipulation on locomotor activity induced by ethanol in male wistar rats
Changing neuroactive steroid levels early in life can affect how adult rats respond to alcohol's stimulating effects.
research Human hair growth ex vivo is correlated with in vivo hair growth: selective categorization of hair follicles for more reliable hair follicle organ culture
Choosing hair follicles at the same growth stage leads to more consistent hair growth experiments.
research The Annual Changes of Clinical Manifestation of Androgenetic Alopecia Clinic in Korean Males and Females: A Outpatient-Based Study
AGA increased yearly, type I most common, and family history and seborrheic dermatitis often linked.
research Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis
Human hair proteins vary by individual, body site, and ethnicity, useful for forensics.
research An in vivo method for the detection of somatic mutations at the cellular level in mice
A new method can detect mutations in mice by observing changes in hair follicle cells.
research TRANSTORNOS DE PERSONALIDADE: ETIOLOGIAS E DESAFIOS DIAGNÓSTICOS
research Exact, time-independent estimation of clone size distributions in normal and mutated cells
A new method accurately estimates clone sizes in cells without considering time.
research Spatiotemporal dynamics of sensory neuron and Merkel-cell remodeling are decoupled during epidermal homeostasis
Merkel cells stabilize nerve endings in the skin, and they change independently of each other.
research Bias in Hair Cortisol Measures for Psychological Stress: Self vs. Professional Collection
Self-collected hair samples can measure stress but may need adjustments for accuracy.
research Proteins in Scalp Hair of Preschool Children
Hair proteins in preschool children and their mothers could indicate developmental changes and health status.
research Categorization of long-lasting hair changes in patients after hematopoietic stem cell transplants
Patients often experience long-lasting changes to their hair after stem cell transplants.
research Age-related changes in human scalp extracellular matrix – implications for the hair follicle?
Older women's scalp cells show changes that could contribute to hair thinning.
research Relationship between neonatal allopregnanolone and neonatal stress: effects on adolescent and adult behaviour /
Neonatal allopregnanolone and stress affect behavior differently in adolescence and adulthood.
research 878 Individual variation in balance between platelet-secreted growth factors causing contradictory effects on hair follicle could potentially impact response to PRP therapy in patients with scalp hair loss
People respond differently to hair loss treatment with PRP because of individual differences in growth factors from platelets.
research Melanocyte Subpopulation Turnover During the Human Hair Cycle: An Immunohistochemical Study
Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.
research Corrigendum: Hair and Salivary Testosterone, Hair Cortisol, and Externalizing Behaviors in Adolescents
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 LC-MS/MS-based reference intervals for hair cortisol in healthy children
Hair cortisol levels change with age, starting high at birth, decreasing until age 6, then rising to adult levels by age 18.
research 132 Genetics of Stress Hormone Concentrations in Hair of Healthy Nursery Pigs and Their Relationship with Back Test Responses
Pig hair cortisol levels are inheritable and linked to stress responses, which could help select for more resilient pigs.
research Variation and Heritability in Hair Diameter and Curvature in an Australian Twin Sample
Hair diameter and curvature are mostly determined by genetics.
research Localization patterns of collagens during growth of human scalp hair
research Variations of scalp, pubic and axillary hair
Pubic hair is thicker than axillary and scalp hair, useful for forensic identification.
research Daily Circle of Calcium Concentration in Hair Observed by X-ray Fluorescence Analysis
Hair can show daily calcium changes, linked to body calcium levels and influenced by hormones, and can help assess calcium metabolism issues.
research Moniletrix of the scalp from almost normal aspect to total alopecia: variable intrafamilial expressiveness
Monilethrix causes different levels of hair loss in family members.
research Efectos de la alteración de los niveles de allopregnanolona durante periodos críticos del neurodesarrollo en la vulnerabilidad al consumo de alcohol
Early NAS level changes affect alcohol consumption vulnerability.
research TrichoScan: combining epiluminescence microscopy with digital image analysis for the measurement of hair growth in vivo.
TrichoScan accurately measures hair growth and showed improved hair counts and thickness after finasteride treatment.
research Step-down approach to concentration of intra-lesional triamcinolone acetonide in treatment of scalp patchy alopecia areata: insights from an open-label randomized trial
Using a higher concentration of triamcinolone acetonide leads to faster hair regrowth in scalp patchy alopecia areata.
