Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

The conclusion is that using drugs to block the TOR pathway might slow aging and prevent age-related diseases.

TRPA1 is crucial for mechanical sensitivity in skin sensory neurons.

The Endocrine Society advised against routine testosterone therapy for women, citing a need for more research on long-term safety and a clear definition of androgen deficiency.

Melatonin in the skin helps protect against damage from stress and UV rays, and could be used to treat certain skin conditions.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

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

The method can effectively extract biomedical information without needing expert annotation, performing better than previous models.

The Rotterdam Study aims to understand various diseases in older adults.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Lifestyle changes can improve body composition, excess male hormone levels, and insulin resistance in women with PCOS.

Androgens may cause hair loss by increasing TGF-beta1 from scalp cells, which inhibits hair cell growth.

Sulforaphane from broccoli can help protect skin from sun damage.

Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

People who are more materialistic often expect life changes from buying things, leading to more debt and credit misuse.

Blood vessels and specific genes help turn cartilage into bone when bones heal.

Blocking JAK-STAT signaling can lead to hair growth.

Silver can help prevent and treat infections but its effectiveness varies and should be weighed against costs and side effects.

Stem cell self-renewal is complex and needs more research for full understanding.

Trilostane effectively improved symptoms in dogs with a certain adrenal gland disorder.

Aging causes skin stem cells to work less effectively.

Dextran sulfate was found to be toxic and ineffective for treating HIV.

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

Turmeric may have benefits for skin health, but more research is needed to confirm its effectiveness.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Probiotic bacteria improved skin and hair health in aged mice.

Minoxidil shortens baldness from chemotherapy by 50.2 days without significant side effects.

Polycystic Ovary Syndrome likely starts in childhood and may be genetic and influenced by early hormone exposure.

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