Air pollution can damage hair and scalp, causing hair loss and inflammation.

Activating TLR5 in the gut can extend lifespan and improve health in aged mice.

The research created a detailed map of skin cells, showing that certain cells in basal cell carcinoma may come from hair follicles and could help the cancer grow.

Low-dose radiation therapy may improve brain function in some Alzheimer's patients and is generally well-tolerated.

Tiny particles from 3D-grown skin cells speed up wound healing by promoting blood vessel growth.

Human stem cells have diverse sources and potential uses in medicine.

CD4+ skin cells may be precursors to basal cell carcinoma.

Signals from skin cells controlled by Rac proteins help turn certain precursor cells into white fat cells.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Some cosmetic procedures show promise for treating hair loss, but more research is needed to confirm their safety and effectiveness.

Women with PCOS have altered brain structure and reduced cognitive performance.

Get head MRI for babies with achondroplasia early, use free immunoglobulin light chains to detect certain neurodevelopmental disorders, and video calls work for speech therapy in patients with facial anomalies.

Skin aging reflects overall body aging and can indicate internal health conditions.

Finasteride may protect brain and improve behavior in rats with liver failure.

Skin stem cells can help improve skin repair and regeneration.

Total glucosides of paeony can help treat skin conditions but need more research for clinical use.

NF-κB signaling is crucial in many diseases and can be targeted for new treatments.

Exosomes show promise for future tissue regeneration.

Traditional Chinese medicinal foods may help manage long-term post-COVID symptoms.

JAK inhibitors effectively treat skin conditions and topical forms are safer.

Eating less can improve stem cell function and increase lifespan.

Old drugs like finasteride and spironolactone are being successfully used for hair loss and skin conditions, and many other drugs show promise for new uses in dermatology.

Different human traits like skin color and hair type vary between populations due to genetic adaptations to the environment.

An educational package was created to teach people about lesser-known herbal medicines in India.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Scientists successfully created and analyzed the structure of a part of the human androgen receptor with specific modulators and a peptide to understand how it binds differently in various tissues.
