840-870 / 1000+ resultsresearch Towards the validation of endogenous steroid testing in wildlife hair
Hair analysis for stress and reproductive hormones in wildlife needs more research for accuracy across species.
research Endocrine profile of the VCD-induced perimenopausal model rat
The rat model showed early perimenopause with regular cycles and low hormones, and late perimenopause with irregular cycles and higher hormone levels.
research Within-person changes of cortisol, dehydroepiandrosterone, testosterone, estradiol, and progesterone in hair across pregnancy, with comparison to a non-pregnant reference group
Hormone levels in hair change during pregnancy, with progesterone increasing significantly compared to non-pregnant women.
research The profile of steroid hormones in human fetal and adult ovaries
Fetal ovaries produce different hormones than adult ovaries, and endocrine-disrupting chemicals may affect this process.
research A quantitative ultra-performance liquid chromatography high-resolution mass spectrometry analysis of steroids from human scalp hair
The method can measure multiple steroids in human hair to study long-term steroid metabolism, especially in newborns and children.
research Risks of Skin, Hair, and Nail Supplements
Some skin, hair, and nail supplements can be toxic, interact with medications, affect lab tests, and may increase cancer risk.
research Relationship of Hair Cortisol Concentration With Perceived and Somatic Stress Indices: Cross-Sectional Pilot Study
Hair cortisol concentration may reflect some physiological stress but doesn't strongly correlate with perceived stress.
research Single-Cell Sequencing Reveals Differential Cell Types in Skin Tissues of Liaoning Cashmere Goats and Key Genes Related Potentially to the Fineness of Cashmere Fiber
Certain genes are linked to the quality of cashmere in goats.
research Upcycling Eggshell Matrix for Sustainable Production of Glycosaminoglycans
Eggshells can be used to sustainably and cheaply produce important compounds like glycosaminoglycans.
research PRF Lysates Modulate Chemokine Expression in Oral Squamous Carcinoma and Healthy Epithelial Cells
PRF lysates reduce inflammation in cancer cells and boost immune response in healthy oral cells.
research Lack of Significant Association between Sex Hormone Concentrations and Atopic Dermatitis in Adolescents and Adults in Two Population-Based Studies
Sex hormones likely don't affect atopic dermatitis in adolescents and adults.
research Biotin Deficiency in Telogen Effluvium: Fact or Fiction?
Biotin deficiency is not a major cause of Telogen Effluvium hair loss.
research A meta-analysis of chemokines in alopecia areata: recruiting immune cells toward the hair follicle
Alopecia areata involves complex immune dysregulation, mainly driven by Th1 activity, suggesting broader treatment strategies.
research Chronic circadian misalignment is a risk factor for hair growth impairment
Disrupted sleep patterns from artificial light can slow hair growth and may lead to hair loss.
research Sex steroid levels in corresponding cerebrospinal fluid and serum samples quantified by mass spectrometry in men
DHEA is the main sex steroid in cerebrospinal fluid, and testosterone in the fluid comes from the blood.
research Postmenopausal hyperandrogenism due to an ovarian sex cord-stromal tumour causing elevated dehydroepiandrosterone sulphate: a case report
An ovarian tumor can cause high male hormones in postmenopausal women.
research Abstracts from the 4th Annual Student Medical Summit
The document concludes that more research is needed to reduce frequent hospital visits, addiction medicine education improves with specific training, early breast cancer surgery findings are emerging, nipple smears are not very accurate, surgery for older melanoma patients doesn't extend life, a genetic condition in infants can often be treated with one drug, doctors are inconsistent with blood clot medication, a certain gene may protect against cell damage, muscle gene overexpression affects many other genes, and some mitochondrial genes are less active in mice with tumors.
research Determining Cortisol in Animal Hair as a Marker of Chronic Stress
Hair cortisol can indicate animal stress but varies with many factors.
research Hair cortisol/cortisone in combined oral contraceptive users: An exploratory analysis
COC use doesn't increase hair stress hormone levels, but hair treatments may affect results.
research Transient skin stretching stimulates immune surveillance and promotes vaccine delivery via hair follicles
Skin stretching can improve vaccine delivery through hair follicles and boost immune response.
research Klinisch redeneren: diagnostiek bij thyreotoxicose in de eerste lijn: een case-report
Diagnosing thyroid disorders is complex and requires thorough testing due to nonspecific symptoms like hair loss.

25% of premenopausal women with Type 1 diabetes have undiagnosed androgen excess disorders.
research Effects of oxytocin receptor agonists on hair growth promotion
OXTR agonists may promote hair growth and be effective for treating hair loss.
research A comprehensive investigation of biochemical status in patients with telogen effluvium: Analysis of Hb, ferritin, vitamin B12 , vitamin D, thyroid function tests, zinc, copper, biotin, and selenium levels
Telogen effluvium is linked to deficiencies in iron, vitamin B12, and thyroid function.
research Cinnamic acid promotes elongation of hair peg-like sprouting in hair follicle organoids via oxytocin receptor activation
Cinnamic acid may help hair grow by activating oxytocin receptors.
research Dihydrotestosterone induces arterial stiffening in female mice
Dihydrotestosterone makes arteries stiffer in female mice by reducing estrogen receptor expression.
research Testosterone: The Male Sex Hormone
More research is needed to understand how testosterone is maintained in adult males.
