Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

Hair growth slows and shedding increases after childbirth, but most women don't experience excessive hair loss.

Researchers developed a reliable method to measure testosterone and epitestosterone in urine for medical and anti-doping use.

High levels of the seizure medication sodium valproate can cause hair loss.

Women with hair loss had higher levels of certain hormones, suggesting a link to a condition like PCOS.

Progesterone and its byproducts control a specific receptor in the brain independently of progesterone receptors, affecting conditions related to the menstrual cycle.

Hair cortisol and cortisone levels may affect how work stress influences depression in Chinese fishermen.

A man with hypoparathyroidism had other health issues that led to a diagnosis of a rare autoimmune disorder, APS-1.

Eating less can improve stem cell function and increase lifespan.

Neuroactive steroids may affect the risk and treatment of alcohol use disorders.

Women with effluvium have higher levels of certain urinary steroids, possibly due to stress and increased adrenal activity.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Finasteride treats enlarged prostate and hair loss, but may cause side effects in some patients.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Stress can stop hair growth in mice, and treatments can reverse this effect.

New treatments for male hypogonadism are effective and should be personalized.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Prostaglandin D₂ might be targeted for new male pattern baldness treatments.

Progesterone boosts alcohol's effect on brain, finasteride counters it.

Hormones might affect the skin condition hidradenitis suppurativa, but their exact role is unclear.

pH, calcium, and reactive oxygen species regulate plant cell growth, with key roles for NADPH oxidases and plasma membrane H+-ATPases.

Finasteride irreversibly affects human steroid 5α-reductase 2, providing insight into its catalytic mechanism and disease-related mutations.

Hair follicles on the scalp interact with and respond to the nervous system, influencing their own behavior and growth.

The study found no link between baldness patterns and androgen levels in men with benign prostate enlargement or prostate cancer.

The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.

Pregnancy reduces anxiety in rats, but finasteride reverses this effect.

Women with hyperandrogenic amenorrhea have similar bone density to healthy women but lower than androgenized women without amenorrhea, and high DHEAS levels might affect bone density.

Finasteride reduces alcohol withdrawal severity and anxiety in mice, but may increase withdrawal severity in some cases.

The study found three different timing patterns of symptoms in women with premenstrual dysphoric disorder.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.
