A severe headache, visual disturbances such as blurred vision and some epigastric pain that is associated with the development of severe pre-eclampsia or eclampsia. These danger signs and symptoms must be reported immediately as soon as possible. A severe headache and visual disturbances are related to severe vasoconstriction and in a severe increase in blood pressure. Epigastric pain is related to hepatic dysfunction. Ankle edema is a common thing during the third trimester of pregnancy. However, the facial edema is associated with increased fluid retention and the progression from mild to severe pre-eclampsia. Increased energy levels aren't associated with a progression of the client's pre-eclampsia or the development of the complications. In fact, some women are reporting an "energy spurt" before the onset of labor. A mild back-ache is just a common discomfort of pregnancy, unrelated to a progression of the client's pre-eclampsia.

Answer: Transcription factors
Explanation:  
The dioxin enters the blood stream and the fat cells and liver cells store it.
While moving inside the cell the dioxin binds to the protein called Aryl hydrocarbon which then binds to the second receptor.  
The complex is then carried to the nucleus of the cell. This tends to on and off certain genes.
This turning on and off of the genes in the cell can lead to serious diseases like cancer, decreased immune function, et cetera.
