... propose that neural innervation of the gonad allows H. aspersa to monitor oocyte production and ensure an adequate supply of gametes prior to ovulation. The ovotestis is innervated by a branch of the intestinal nerve in which the majority of axon fibres measure <0.2 μm in diameter. We found a strong...

...Daisuke Uchida; Michiaki Yamashita; Takeshi Kitano; Taisen Iguchi SUMMARY Large numbers of apoptotic early diplotene oocytes were observed during the transition from ovary-like undifferentiated gonadal tissue to testes during sex differentiation in presumptive males of the zebrafish ( Danio rerio...

... be of importance for the interaction with odorants, as well as in the intracellular loops 2 and 3, which might be responsible for interactions with specific G-proteins. The results of functional expression studies in Xenopus oocytes, comparing distinct receptor types, support the idea that class I receptors...
