Accurate knowledge of placental lactogen localization is fundamental to any hypothesis of its synthesis and secretion. We used locally generated monoclonal and polyclonal antibodies from three separate sources to localize ovine placental lactogen immunoreactivity on light and electron microscope Lowicryl K4M sections of ovine placentomes of 97-145 days of(More)
Fertility has unanimously declined across the entire post-communist region. This study explores the variation in fertility trends over time among these countries and assesses to what degree three explanations are applicable: second demographic transition (SDT), postponement transition (PPT) or reaction to the economic crisis. Moreover, on the basis of SDT(More)
The sites of intracellular synthesis and storage of human placental lactogen (hPL) and human chorionic gonadotropin (hCG) are controversial. We have used one of the most sensitive methods, cryoultramicrotomy and immunogold labelling, to localise these hormones at the electron-microscopic level. In both 12-week and term placentas hCG and hPL are present(More)
