The function of Drosophila YELLOW members is relative to reproduction, and studies showed that yellow-g and yellow-g2 in Drosophila playing a female-specific role in egg development [ 23].
For the purpose of the present review, the limitations associated with the use of WF as a test material would be expected to apply equally to lifetime studies and reproduction studies and these studies will not be considered in depth here.
Therefore it is possibly not surprising that the Aubin-Horth study shows up-regulation of genes involved in reproduction and this study shows some opposite effects.
Further researches are necessary to better understand the potential use of the trace elements in otoliths on fish ecology and populations dynamic studies (e.g., migrations, reproduction and growth studies of farmed, escaped, and wild fish), as well as to evaluate their applicability on sustainable coastal aquaculture and fisheries management.
Laurent Keller, an evolutionary biologist at the University of Lausanne in Switzerland who has done similar studies in ants, says that until recently, researchers have failed to recognize these bizarre forms of reproduction, and more studies like this are needed to find out how common they are.
The predictive power of in vitro receptor binding and in vivo toxicity in mammals for endocrine activity in fish was assessed by comparing their outcome with results of reproduction and biomarker studies with fish, focusing on sexual endocrine endpoints, from an UBA report [27] and the literature cited therein (see Table 3).
It has traditionally been used as a model animal in toxicology experiments [ 4], and in hematology, reproduction and histophysiology studies [ 5- 7].
PFOS reduced postnatal survival and body weight gains in dams and pups in reproduction and development studies of mice and rats (Lau et al. 2003; Thibodeaux et al. 2003).
Animal work makes a compelling case for a role for selenium in successful reproduction and recent studies in women with RPL have suggested that selenium deficiency may contribute to RPL [ 10, 14- 16].
