PCOS is a complex condition with major health impacts, needing more research for better diagnosis and treatment.

Rosacea is a skin condition with unclear causes, classified into four subtypes.

Improving artificial vascular grafts requires better materials and surface designs to reduce blood clotting and support blood vessel cell growth.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Metformin helps with menstrual cycles and insulin levels in PCOS but is less effective for hair growth, diabetes prevention, and weight loss, and may improve fertility and reduce diabetes risk.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

Women with the NIH type of PCOS have more obesity and higher risk of diabetes and heart disease than those with other types of PCOS.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

The document concludes that insulin resistance is key in PCOS development and early treatment is crucial to prevent complications.

Growing human skin cells in a 3D environment can stimulate new hair growth.

Human skin can make serotonin and melatonin.

Melatonin is important for skin health and protection, and can be made by the skin or applied to it.

Visible light can damage skin and most sunscreens don't block it well; more research is needed on its effects and protection methods.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

Cancer treatments targeting specific cells and the immune system can cause skin, mouth, hair, and nail problems, affecting patients' quality of life and treatment adherence.

Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.

Myrtle has various health benefits and potential for medicine development.

Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.

Liposomal systems show promise for delivering drugs through the skin but face challenges like high costs and stability issues.

Targeting the IL-23/IL-17 pathway effectively treats several inflammatory skin diseases.

RNAi-based biopesticides could be safe and effective for pest control with careful development and risk assessment.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Inflammation may be linked to hair loss, and targeting specific enzymes could help treat it.

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.

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

Hibiscus plant extracts may have health benefits like lowering blood pressure and protecting the heart.

Modern lifestyles, including poor diet, stress, and long-term use of certain medications, hinder the body's ability to heal from inflammation, leading to chronic diseases.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.
