SYNOPSIS. This paper summarizes recent work on various aspects of hormonal control of regeneration in the crustacean, Uca pugilator. Hormonal control in this crab is effected by means of the crustactean steroid hormones, the ecdysteroids. New evidence is presented supporting a role for the retinoid hormones, all-trans retinoic acid and 9-cis retinoic acid, in the control of regeneration in thes...

the majority of cancer treatments are invasive. gonadal injuries cause reductions in fertility which results in lack of hope for conception in cancer patients and frustration for their partners. fortunately, current advancements in cryopreservation and transplantation sciences regarding fertility preservation lead to cryostorage of gonads and preservation prior to the onset of chemo- and radiot...

aflatoxins (afs) are natural contaminants of feed and feedstuffs, thus the study of the noxious effects ofthese agents on the male reproductive system is of outstanding importance. our aim for this study is theevaluation of the effects of oral administration of aflatoxin b1 on the reproductive hormonal changes in adult male rat. twenty eight wistar strain male rats were selected for this study....
