Masculine facial features may not reliably indicate heritable health, and more research is needed.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

Different types of stem cells and their environments are key to skin repair and maintenance.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Silver nanoparticles coated with substances like PEG showed strong antibacterial effects and improved wound healing when used in hydrogels.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

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

Surgery is the main treatment for liver hydatidosis, but has risks; albendazole is the most effective drug but can have side effects.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.
