DNA ploidy in thin melanoma

Pathology, 1988
DNA ploidy in benign nevi (BN), thin non-metastasizing melanomas (TNM) and thin metastasizing melanomas (TMM) was investigated using an image analyser to determine whether characteristics such as nuclear area (NA) and nuclear integrated optical density (IOD) could be used to distinguish between these lesions.

The determination of megakaryocyte ploidy

The International Journal of Cell Cloning, 1990
Methods which have been used to determine megakaryocyte ploidy in animals and humans are reviewed. Although the number of megakaryocyte nuclear units counted in bone marrow squashes is roughly proportional to ploidy, accurate determinations of DNA content require the use of microphotometry or flow cytometry.

Monkeying around with ploidy

Molecular Ecology, 2012
Inferences of whole genome duplication (WGD) events accompany the annotation of every newly sequenced plant genome, but much remains unknown about the evolutionary processes and pathways relating to WGD (Soltis et al. 2010). What ecological, biogeographical and genetic factors cause WGD to occur in nature? How does WGD affect gene expression?

Ploidy differences in Cryptococcus albidus

Mycopathologia et Mycologia Applicata, 1970
Presumed haploid and diploid cultures ofCryptococcus albidus were analysed for their DNA content per cell. A ratio of approximately 1:2 was obtained by relating the DNA content per cell of the two phases to ploidy. As the diplophase formed neither longitudinally septated cells nor ballistoconidia, the earlier suggestions thatCryptococcus is closely ...

Ploidy Regulation of Gene Expression

Science, 1999
Microarray-based gene expression analysis identified genes showing ploidy-dependent expression in isogenic Saccharomyces cerevisiae strains that varied in ploidy from haploid to tetraploid. These genes were induced or repressed in proportion to the number of chromosome sets, regardless of the mating type.

Megakaryocytic Ploidy in Myelodysplastic Syndromes

Leukemia & Lymphoma, 1993
The megakaryocytic ploidy was microfluorometrically measured in 12 normal controls and 15 myelodysplastic syndrome (MDS) patients using DAPI (4',6-diamidino-2-phenylindole) staining after destaining of the Wright-Giemsa (WG) stain. MDS patients had slightly more immature megakaryocytes when compared with normal controls.

DNA ploidy: Early malignant lesions

Journal of Cellular Biochemistry, 1992
The nuclear DNA content of prostate cancer specimens, both needle biopsies and aspiration biopsy specimens as well as transurethral resection (TUR) chips and radical prostatectomy specimens, can now be reliably measured by standardized methods of flow and static image cytometry.

Ploidy Study in Sporothrix schenkii

Fungal Genetics and Biology, 1999
Sporothrix schenckii is a dimorphic fungus that is pathogenic for humans. No sexual cycle has been reported for this fungus and little is known of its genetic constitution. To inquire into the ploidy state of Sporothrix schenckii, different approaches were followed: DNA content during transition from conidia to yeast, survival to ultraviolet ...
