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 Ferulic acid inhibits catamenial epilepsy through modulation of female hormones
Ferulic acid may help control menstrual cycle-related epilepsy by affecting female hormones.
research Determinants of hair cortisol and hair cortisone concentrations in adults
Hair cortisol and cortisone levels increase with age, are higher in diabetics, vary by gender, decrease with frequent hair washing, and are lower in winter.
research Effects of shampoo and water washing on hair cortisol concentrations
Washing hair with water or shampoo lowers cortisol levels in hair.
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 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 Endogenous steroid hormones in hair: Investigations on different hair types, pigmentation effects and correlation to nails
Body hair isn't a good substitute for scalp hair in steroid analysis.
research Determination of cortisone and cortisol in human scalp hair using an improved LC-MS/MS-based method
Cortisone in hair is a more reliable indicator of stress hormone exposure than cortisol.
research Effects of glucocorticoid on human dermal papilla cells in vitro
Dexamethasone may cause hair loss by stopping cell growth.
research A randomized placebo-controlled study on the effects of pioglitazone on cortisol metabolism in polycystic ovary syndrome
Pioglitazone improved insulin sensitivity and altered cortisol metabolism in PCOS patients.
research Hair Cortisol in Sheltered Cows and Its Association with Other Welfare Indicators
High hair cortisol levels indicate stress in cows due to poor shelter conditions and health issues.
research Hair Cortisol Concentrations in Adolescent Girls with Anorexia Nervosa are Lower Compared to Healthy and Psychiatric Controls
Adolescent girls with anorexia nervosa have lower hair cortisol levels than healthy and psychiatric peers.
research The anti-inflammatory and analgesic activities of 2Br-Crebanine and Stephanine from Stephania yunnanenses H. S.Lo
2Br-Crebanine and Stephanine reduce inflammation and pain effectively.
research Novel insights into the molecular mechanisms underlying generalized glucocorticoid resistance and hypersensitivity syndromes
Genetic defects in the glucocorticoid receptor gene can cause conditions with abnormal sensitivity to stress hormones, and other factors may also affect this sensitivity.
research Recent advances in the molecular mechanisms causing primary generalized glucocorticoid resistance
Mutations in the NR3C1 gene cause a rare condition that affects hormone signaling and can lead to various symptoms, with dexamethasone as a treatment option.
research Acute Stress-Induced Changes in Follicular Dermal Papilla Cells and Mobilization of Mast Cells: Implications for Hair Growth
Stress can slow hair growth by affecting certain cells and pathways.
research Interaction between early postnatal neurosteroid manipulations and adult infusion of neurosteroids into CA1 hippocampal region on the open field behaviour
Early neurosteroid changes can alter adult brain function and behavior.
research Presence of mast cells and mast cell degranulation in scalp biopsies of telogen effluvium
The study suggests that mast cells might be involved in the hair loss condition telogen effluvium and could be a target for treatment.
research Fast and Noninvasive Hair Test for Preliminary Diagnosis of Mood Disorders
A hair test shows promise for early mood disorder diagnosis.
research Prefrontal 5α-reductase 2 mediates male-specific acute stress response
5α-reductase 2 is crucial for stress response in male rats.
research The tail-tale of stress: an exploratory analysis of cortisol levels in the tail-hair of captive Asian elephants
Elephant tail-hair can show past stress levels, matching times when stressful events happened.
research Restricted effects of androgens on glucocorticoid signaling in the mouse prefrontal cortex and midbrain
Androgens can affect glucocorticoid signaling in specific mouse brain areas.
research Altered hypothalamus functional connectivity and psychological stress in patients with alopecia areata
Altered hypothalamic activity may contribute to stress in alopecia areata patients.
research Stem cell secretome as a mechanism for restoring hair loss due to stress, particularly alopecia areata: narrative review
Stem cells and their secretions could potentially treat stress-induced hair loss, but more human trials are needed.
