August 2016 in “Journal of Investigative Dermatology” This research reported that STAT5 activation in the dermal papilla plays a crucial role in triggering anagen entry during post-developmental hair follicle cycling.
June 2025 in “Molecular Therapy — Nucleic Acids” In this study, researchers identified a specific DNA aptamer, Ap.OR2AT4.17, that effectively prolonged hair growth and increased hair shaft elongation in organ-cultured human hair follicles by targeting the olfactory receptor OR2AT4. This finding suggests the aptamer's potential as a novel therapy for hair loss disorders.

,
July 2004 in “Fertility and Sterility” Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.
21 citations
