... nutrient stores to develop eggs. To determine how larval nutrition affects the endocrinology of egg development in these females, we manipulated the quantity of larval food and measured in vitro production of juvenile hormone (JH) by corpora allata (CA) and ecdysteroids by ovaries. Newly emerged A. aegypti...

... in all three highly conserved FAD-binding sequences, which distinguished it from other NOS sequences. RT-PCR showed that the Gl-NOS mRNA was present in testis,ovary, gill, eyestalk neural ganglia, thoracic ganglion and Y-organ. NOS mRNA varied between preparations of Y-organ, thoracic ganglion and gill...

...Abrahim S. Caroci; Yiping Li; Fernando G. Noriega SUMMARY We investigated the relationship among nutritional reserves,previtellogenic ovary development and juvenile hormone (JH) synthesis in Aedes aegypti female mosquitoes. By raising larvae under different nutritional regimes, two adult phenotypes...

... in MYP as well as in other biochemical components in the ovary and testis were examined in the course of gametogenesis in Pseudocentrotus depressus . Before gametogenesis, both the ovary and testis contained large quantities of proteins, lipids and polysaccharides. MYP reached about 80% of total protein...

...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...

.... Hydrocarbons are not synthesized by the ovaries, but are delivered by hemolymph lipoproteins and accumulate within the basal oocytes. A native B. germanica hydrocarbon, [ 3 H]3,11-dimethylnonacosane, injected into adult females of various ages, was taken up by the ovaries in relation to oocyte growth. Ovarian...

...T. Ravid; A. Tietz; M. Khayat; E. Boehm; R. Michelis; E. Lubzens ABSTRACT By the end of oocyte development, the ovaries of Penaeus semisulcatus have accumulated almost equal amounts (approximately 16 mg lipid g −1 protein) of phospholipids and triacylglycerols. The phospholipids consist mainly...

.... However, RPCH did not affect the ovary in vitro when only RPCH, muscle and ovarian explants were used. But when RPCH, thoracic ganglia, which are known to contain gonad-stimulating hormone-like (GSH-like) activity, and ovarian explants were incubated together, significant ovarian maturation ensued...
