In primary cultures of immature male rainbow trout (rt) hepatocytes, vitellogenin (Vg) gene expression is regulated by E(2) via the estrogen receptor (ER). However, steroids other than estrogens can also stimulate Vg gene expression. These steroids are hardly converted into E(2) during incubation and their stimulatory activity is completely inhibited by(More)
Microcrystalline silicon thin films were formed on quartz substrates by ultrahigh-frequency ~UHF! plasma enhanced chemical vapor deposition from a mixture of silane (SiH4) and hydrogen (H2) gases at low substrate temperatures (Ts). The UHF plasma was excited at a frequency of 500 MHz. The deposition rate and the crystallinity of the films were investigated(More)
