The skin is vital for protection, temperature control, fluid balance, immunity, and sensing, with damage affecting daily life and mental health.

Stem cell niches support, regulate, and coordinate stem cell functions.

Androgen receptor activity blocks Wnt/β-catenin signaling, affecting hair growth and skin cell balance.

Food deprivation increases MST enzyme in the brain, possibly affecting energy balance.

Pregnancy can change skin disease severity, with some conditions improving and others worsening, and treatment should balance benefits and fetal safety.

Finasteride treatment changes brain steroid levels and receptors, affecting brain function even after stopping treatment.

Steroid sulfatase is important for activating hormones that affect memory, brain function, and certain diseases, and could be a target for treating hormone-related disorders.

Researchers found 44 proteins that change during different hair growth stages and may be important for hair follicle function.

Testosterone is crucial for development, growth, and various body functions in mammals.

Tacrolimus causes fewer acute rejections than cyclosporin A in kidney transplants but doesn't necessarily improve kidney function after one year; cardiovascular risks and side effects vary between the two drugs.

The Rotterdam Study found risk factors for elderly diseases, links between lifestyle and genetics with health conditions, and aimed to explore new areas like DNA methylation and sensory input effects on brain function.

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.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Dihydrotestosterone (DHT) doesn't affect rat skin cell growth, but it does change cell cycle, protein levels, and other cell functions, potentially shortening hair growth cycle.

New indole-based compounds, particularly cemtirestat, show promise as dual-function drugs for diabetic complications.

Hormonal changes and psychological issues can cause sexual dysfunction in postmenopausal women. Behavioral therapy is recommended first, with hormone replacement helping some symptoms but not libido. Testosterone can improve libido, but its effects on overall sexual function are unclear. Emotional and relationship issues should be addressed before using medication, and the benefits and risks of testosterone supplementation should be considered.

Brepocitinib 30mg is most effective for moderate-to-severe alopecia areata, but ritlecitinib 50mg may offer a better balance of safety and effectiveness.

Heat-treated Limosilactobacillus fermentum with menthol, salicylic acid, and panthenol promotes hair growth and balances scalp microbiome in people with androgenetic alopecia.

Diuretics help the body get rid of excess salt and water by acting on the kidneys in different ways.

Combining narrow-band ultraviolet B light and stem cell transplantation helps repigmentation in vitiligo by maintaining calcium balance in mice.

Using developmental signaling pathways could improve adult wound healing by mimicking scarless embryonic healing.

Impaired ABCA5 activity disrupts cholesterol balance in hair follicle cells, affecting hair growth.

The document concludes that various surgical techniques and postoperative care are used to protect eye health, improve vision, and restore facial balance in people with facial paralysis.

Male and female skin differ due to hormones, affecting conditions like hair loss, acne, and skin cancer, and suggesting a need for gender-specific treatments.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

Finasteride for hair loss may cause persistent sexual symptoms, depression, anxiety, and lower quality of life.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Zebrafish larvae are used to study and find treatments for ear cell damage because they are easier to observe and test than mammals.

Pharmacists should interpret lab data and perform physical exams to improve patient care.
