Umbilical cord plasma-derived exosomes from preeclamptic women induce vascular dysfunction by targeting HMGCS1 in endothelial cells.

abstract：:Combined staining of non-cultured interphase nuclei from hydatidiform moles with distamycin A and DAPI resulted in the presence of specific stained interphase bodies. A mean number of six interphase bodies was observed in moles with a diploid karyotype and a mean number of nine interphase bodies was observed in triplo...
