research SERUM STEROIDS AND PITUITARY HORMONES IN FEMALE PUBERTY: A PARTLY LONGITUDINAL STUDY
During puberty, hormone levels rise, with early increases in some steroids and most menstrual cycles becoming regular by six years after menarche.
research Prostanoids and Hair Follicles: Implications for Therapy of Hair Disorders
Prostanoids, like prostaglandins and thromboxane A2, can both enhance and inhibit hair growth, and understanding their effects could help treat hair disorders.
research LINCS Dataset-Based Repositioning of Dutasteride as an Anti-Neuroinflammation Agent
Dutasteride may help reduce brain inflammation and improve cognition.
research Neuroendocrinology of the hair follicle: principles and clinical perspectives
Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.
research Highly efficient nucleophilic addition of alkyl Grignard reagents to 17-ketosteroids in the presence of cerium(III) chloride: Synthesis of 17α-propyl-17β-hydroxy-4-androsten-3-one, an androgen receptor antagonist
