Tiny pollution particles called PM2.5 can harm skin cells by causing stress, damage to cell parts, and cell death.

About 7% to 15% of Iranian women have polycystic ovary syndrome, depending on the criteria used to diagnose it.

Planarian regeneration begins with a specific gene activation caused by injury, essential for healing and tissue regrowth.

Minoxidil and finasteride treat hair loss in men, while minoxidil treats hair loss in women.

MK-0773 safely increased muscle mass but did not improve muscle strength or function in elderly women with sarcopenia.

More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

Male and female bodies respond differently to stress, influenced by hormones and development stages, with implications for stress-related diseases.

Sebocytes play a key role in controlling androgen levels in human skin.

High levels of male hormones, insulin resistance, and obesity are closely linked and worsen polycystic ovary syndrome, but more research is needed to improve treatments.

Genetic variation in the androgen receptor gene mainly causes early-onset hair loss, with maternal inheritance playing a key role.

The ZIP7 gene helps control zinc levels in cells by moving zinc from the Golgi apparatus to the cytoplasm.
