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

3D microenvironments in microwells improve hair follicle stem cell behavior and hair regeneration.

Traditional treatment for pediatric alopecia areata is most effective and should be first choice.

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

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.

Nitric oxide is important for skin functions and both helps protect against and contributes to skin inflammation and sensitization.

Children's screen time increased during the pandemic, causing various health issues.

Dihydrotestosterone changes some hormone-related gene expressions in rat pituitary glands but doesn't affect the estrous cycle.

Androgen levels can increase at any age, affecting symptoms like acne, hair loss, and prostate size.

Eating less can improve stem cell function and increase lifespan.

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

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.

The combination of azelaic acid, minoxidil, and caffeine significantly increased the survival of skin flaps by affecting certain body channels and nitric oxide levels.

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

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

Gut flora changes could potentially indicate depression, but more research is needed.

The document concludes that managing health issues like menopause, cardiovascular risk, and hair loss is crucial for promoting longevity in aging women.

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.

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

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.

Nerve growth factor helps cashmere goat hair cells grow and is more active during the hair growth phase.

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

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

Dental pulp stem cells might not reliably become neurons.

Histone demethylases play a key role in the development of many diseases and may be targets for treatment.

The document concludes that pig iPSCs show promise for transplant therapies and the field is advancing in controlling cell behavior for biology and medicine.

Low level laser therapy may help regenerate hair cells in the ear after damage from gentamicin.

Anorexia Nervosa and Bulimia Nervosa are complex eating disorders with increasing incidence among young females, significant morbidity, and varying mortality rates, requiring more research for better treatment.
