Wnt1/βcatenin signaling is crucial for heart repair after injury.

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

Telogen effluvium is a reversible hair loss condition that requires a detailed diagnosis and often resolves on its own.

Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

Opioid painkillers can cause many side effects, including breathing problems and addiction, but are generally considered safe when used properly.

Lower doses of treatments for hirsutism and acne in PCOS are effective and cause fewer side effects.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Microneedles improve drug delivery in various body parts, are safe and painless, and show promise in cosmetology, vaccination, insulin delivery, and other medical applications.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Facial feminization surgery is effective in helping transgender women appear more feminine and has high patient satisfaction.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Early detection and intensive treatment of diseases caused by Staphylococcus aureus toxins are crucial for reducing severe health effects.

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

Fat cells in the skin help start healing and form important repair cells after injury.

Higher doses of cranial irradiation are linked to permanent hair loss.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Exposure to finasteride in the womb caused lasting reproductive issues in male rats.

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.
