research ANTI-ALOPECIA ACTIVITY OF MORINGA (MORINGA OLEIFERA LAMK.) SEED OIL AGAINST DIHYDROTESTOSTERONE-INDUCED RABBITS
Moringa seed oil helped hair growth in rabbits, with the highest dose being most effective.
research Pharmacokinetic parameters and mechanisms of inhibition of rat type 1 and 2 steroid 5α-reductases: determinants for different in vivo activities of GI198745 and finasteride in the rat 3 3Abbreviations: r5AR1, rat 5α-reductase 1; r5AR2, rat 5α-reductase 2; and DHT, dihydrotestosterone.
GI198745 is more potent and longer-lasting than finasteride, potentially better for treating hair loss.
research 25 years of ERβ: a personal journey
ERβ has potential in treating prostate cancer and neurodegenerative diseases, but human studies are needed before clinical use.
research Synthesis of 17β-N-arylcarbamoylandrost-4-en-3-one derivatives and their anti-proliferative effect on human androgen-sensitive LNCaP cell line
