research Biochemical and Structural Characteristics, Gene Regulation, Physiological, Pathological and Clinical Features of Lipocalin-Type Prostaglandin D2 Synthase as a Multifunctional Lipocalin
Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

research Hair Loss and Hair Restoration in Women
Hair loss in women is complex to diagnose and treat, and hair restoration should be done by experts. Using minoxidil before surgery can help manage post-surgery hair shock loss. The Follicular Unit Transplantation method is recommended for women due to its speed, no need for shaving, and better graft quality. Strategies like L, T, and reverse L patterns can help restore central hair density, and regenerative methods can improve graft survival in hair transplants.
