The blockage in the G 1 phase of the cell cycle in the dormant shoot apex of ash.

Planta

Cottignies A.
PMID: 24310888
Planta. 1979 Oct;147(1):15-9. doi: 10.1007/BF00384584.

The shoot apex of the terminal bud was studied in four successive physiological states: during dormancy, when dormancy breaks, during the third week after the break of dormancy, and during a later typical period of active growth. DNA content...

Nuclear DNA changes within Helianthus annuus L.: origin and control mechanism.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Cavallini A, Zolfino C, Natali L, Cionini G, Cionini PG.
PMID: 24232467
Theor Appl Genet. 1989 Jan;77(1):12-6. doi: 10.1007/BF00292309.

Previous results suggested that the amount of nuclear DNA varies in one and the same progeny of Helianthus annuus, depending on the head portion in which seeds have developed. Accordingly, cytophotometric determinations were carried out in a selfed line,...

Nuclear Fractal Dimensions as a Tool for Prognostication of Oral Squamous Cell Carcinoma.

Journal of clinical and diagnostic research : JCDR

Yinti SR, N S, Boaz K, Lewis AJ, Ashokkumar PJ, Kapila SN.
PMID: 26674013
J Clin Diagn Res. 2015 Nov;9(11):EC21-5. doi: 10.7860/JCDR/2015/12931.6837. Epub 2015 Nov 01.

BACKGROUND: Carcinogenesis follows complex molecular alterations, which are triggered by subtle chromatin architectural changes that are imperceptible to the human eye. As the treatment decisions in Oral Squamous Cell Carcinoma (OSCC) are hindered by the imprecise clinical stage determination...

Image analysis of cell proliferation and differentiation in the thymus of the newtPleurodeles waltlii Michah. by SAMBA 200 cell image processing.

Wilhelm Roux's archives of developmental biology

Moustafa Y, Brugal G.
PMID: 28305455
Wilehm Roux Arch Dev Biol. 1984 May;193(3):139-148. doi: 10.1007/BF00848889.

The relationships between cell kinetics and nuclear transformations related to cell differentiation were investigated in the thymus of the newt by means of image analysis. A SAMBA 200 cell image processor was used to compute 18 densitometric, textural and...

Ploidy Analysis and Ki-67 Expression in Myelodysplastic Syndromes.

Hematology (Amsterdam, Netherlands)

Ben-Ezra JM, Trinh K, Harris AC, Kornstein MJ.
PMID: 27416530
Hematology. 1998;3(3):215-22. doi: 10.1080/10245332.1998.11746393.

BACKGROUND: The Myelodysplastic Syndromes (MDS) are disorders involving clonal proliferative activity in the bone marrow that can lead to marrow failure and acute leukemia. This study was undertaken to evaluate the relationships between clinical factors, type of MDS, DNA...

Pituitary Changes in Ataxia-Telangiectasia Syndrome: An Immunocytochemical, In Situ Hybridization, and DNA Cytometric Study of Three Cases.

Endocrine pathology

Kovacs K, Giannini C, Scheithauer BW, Stefaneanu L, Lloyd RV, Horvath E.
PMID: 12114723
Endocr Pathol. 1997;8(3):195-203. doi: 10.1007/BF02738786.

Ataxia-telangiectasia (AT) syndrome (cerebellar ataxia, oculocutaneous telangiectasias, immunodeficiency, susceptibility to infections, and neoplasia) is associated with cyto- and nucleomegaly in several organ systems. Our aim was to determine (1) whether such cellular abnormalities in the pituitary selectively involve specific...

Genome re-assignment of Arachis trinitensis (Sect. Arachis, Leguminosae) and its implications for the genetic origin of cultivated peanut.

Genetics and molecular biology

Robledo G, Lavia GI, Seijo G.
PMID: 21637581
Genet Mol Biol. 2010 Oct;33(4):714-8. doi: 10.1590/S1415-47572010005000079. Epub 2010 Dec 01.

The karyotype structure of Arachis trinitensis was studied by conventional Feulgen staining, CMA/DAPI banding and rDNA loci detection by fluorescence in situ hybridization (FISH) in order to establish its genome status and test the hypothesis that this species is...

Survival of a psychrophilic marine Vibrio under long-term nutrient starvation.

Applied and environmental microbiology

Novitsky JA, Morita RY.
PMID: 16345219
Appl Environ Microbiol. 1977 Mar;33(3):635-41. doi: 10.1128/aem.33.3.635-641.1977.

Ant-300, a psychrophilic marine vibrio isolated from the surface water of the Antarctic convergence, was starved for periods of more than 1 year. During the first week of starvation, cell numbers increased from 100 to 800% of the initial...

Accuracy of optical density measurement of cells. 1: Low resolution.

Applied optics

Smeulders AW, Kate TK.
PMID: 20490051
Appl Opt. 1987 Aug 15;26(16):3249-57. doi: 10.1364/AO.26.003249.

In this paper we analyze factors influencing the accuracy and precision of optical density measurement of light microscopical objects. The study is applied to the DNA content of Feulgen-stained cells using a lowresolution, TV-equipped microscope connected to a digital...

Image cytometry characterization of ploidy level, proliferative activity and chromatin pattern in 50 nasal polyps.

International journal of oncology

Hassid S, Choufani G, Elkattabi O, Dawance S, Decaestecker C, Brugmans M, Danguy A, Pasteels J, Salmon I, Kiss R.
PMID: 21541493

A computer-assisted microscope analysis of Feulgen-stained nuclei was carried out on a series of 50 nasal polyps in order to try to identify specific biological subgroups. The present series of 50 nasal polyps includes single polyps both associated (n=9)...

The use of nuclear-DNA content to monitor the chemosensitivity of human non-small-cell-lung (nsclc) and colorectal cancers xenografted onto nude-mice.
