Masculinization of Nile Tilapia (Oreochromis niloticus) through Immersion in 17α- Methyltestosterone or 17α-Methyldihydrotestosterone
One of the most common techniques for producing mono-sex populations is steroid-induced sex inversion. This involves the administration of synthetic androgens (to produce male populations) or estrogens (to produce female populations). Several methods of steroid administration are possible, including injection, microencapsulation, feeding of steroid, and immersion of fry in steroid solutions. Th...
متن کاملMicrobial Hydroxylation of 16α, 17α-Epoxyprogesterone by Penicillium Decumbens
Microbial transformation has been successfully applied in the production of steroid intermediates with therapeutic use and commercial value in pharmaceutical industry due to its high regio- and stereo-selectivity. As such, it is still important to screen microbial strains with novel activity or more efficient abilities in the development of the commercial steroid industry. Biotransformation of ...
متن کاملPhotodegradation of 17α-ethynylestradiol in nitrate aqueous solutions
17α-Ethynylestradiol (EE2) has gotten growing concerns due to its widely detected in the environment and high estrogenic potency. However, the knowledge on the photochemical behaviors of EE2 in natural waters is still limited. Herein, the photodegradation and estrogenic potency variation of EE2 induced nitrate were studied using a sunlight simulator consisted by a 300 W medium pressure mercury ...
متن کاملComparing Methods of 17α-ethinylestradiol (EE2) Determination in Surface Water
We compared methods of determination of 17α-ethinyloestradiol (EE2) in surface water in Kielce, Poland. EE2 plays a role as a contraception agent and it is commonly used as an active agent in contraception pills. During studies three methods of EE2 determination were checked: TLC, HPLC, and ELISA assay. Samples of contaminated water were taken from eight points on four rivers crossing Kielce ci...
متن کاملSynthesis and chemical reactions of the steroidal hormone 17α-methyltestosterone.
Structural modifications of natural products with complex structures like steroids require great synthetic effort. A review of literature is presented on the chemistry of the steroidal hormone 17α-methyltestosterone that is approved by Food and Drug Administration (FDA) in the United States as an androgen for estrogen-androgen hormone replacement therapy treatment. The analog also offers specia...
