Silver-stained cells from 49 parents with a history of several abortions were compared with cells from 35 parents with normal liveborn children. The modal and mean number of silver-stained NORs (Ag-NORs) observed on D- or G-group chromosomes was similar in both groups and between males and females.
A reliable technique for staining human chromosomal nucleolar organizers (NOR's) with silver solutions is described. The NOR's can be selectively stained dark brown by silver solutions leaving the chromosome arms unstained and available for counterstaining with orcein or Giemsa dyes. Unequivocal ide
Chromosomes with Ag staining that varies from one metaphase to the other can be distinguished from those with an Ag-staining that is the same in all metaphases. The intercellular variation of an Ag-NOR can be attributed to many different factors. Whatever the importance of technical factors, they do
Background. It is believed that in the early stages of hepatocarcinogenesis, some adenomatous hyperplasias (AH) progress to early hepatocellular carcinoma (eHCC), and that many eHCC develop into overt hepatocellular carcinoma (HCC) through nodule-in-nodule formation. However, the proliferative activ
