Control of reproduction is vital to aquaculture and includes artificial propagation as well as management of unwanted recruitment. Developments in manipulation of the reproductive system provide options to enhance production. Nile tilapia, Oreochromis niloticus, spawning was managed by photoperiod and temperature manipulation. A controlled light cycle of 20L:4D and water temperature of 26 ± 2°C...

Anther culture is a relatively easy and high-efficiency technique; however, low efficiency in plant regeneration may restrict its use crop breeding. Activated charcoal often used vitro culture, it ameliorate or hinder growth depending on genotype tissue used. Pepper one of the main vegetable crops Solanaceae family, but some pepper genotypes are known to be recalcitrant androgenesis formation h...

The adult Wistar strain albino rats were vasectomised by conventional method and maintained for six months. The vasectomized rat testis had elevated water content with depleted dry matter. Glycogen content was increased with indication of mobilization of hexoses into HMP pathway. The vasectomized rat testis showed preferential utilisation of triglycerides. In view of increased 3 beta-HSD and 17...

PURPOSE Cytochrome P450 17α-hydroxylase/17,20-lyase (CYP17A1) is a key enzyme in the androgen biosynthesis pathway. CYP17A1 has been focused on because of the promising results of a potent CYP17A1 inhibitor in the treatment of castration-resistant prostate cancer (CRPC). A hypothesis that intratumoral androgenesis may play a role in the progression of CRPC has recently been postulated. Thus, we...
