regions as diagnostic determinants for malignancy.
Different researchers have carried out different methods to assess the grading of the different types of ameloblastomas of which one of the methods which assess the proliferative activity of ameloblastoma are argyrophilic nucleolar organizer
regin (AgNOR) which stains the proteins with silver stain which is associated with active nucleolar organizer
regions (NOR|), these are DNA loops that transcribe to ribosomal RNA directs protein synthesis and ribosomal formation.
The objectives of this study were to compare the argyrophilic nucleolar organizer
region (AgNOR) parameters and estrogen receptor status with grades of invasive ductal carcinoma of breast.
2016), an integrated physical map of constitutive heterochromatic regions (Het), ribosomal loci (rDNA) and nucleolar organizer
regions (NORs) in a single accession of this variety is unavailable, that could help to correlate chromosomes with genetic linkage maps and the future whole-genome sequence of the species.
El nucleolo esta organizado en torno a segmentos de ADN especificos llamados regiones organizadoras nucleares (en ingles, NORs, nucleolar organizer
Mesquita RA found higher numbers of Argyrophilic Nucleolar Organizer
Regions (AgNORs) and proliferating cell nuclear antigen (PCNA)-positive cells in ossifying fibroma than in peripheral ossifying fibroma indicating higher proliferative activity in ossifying fibroma, X-ray diffraction analysis indicated that the mineral phase of both central and peripheral tissues consists of apatite crystals and that the crystallinity of these apatites is lower than that of bone apatite.
During mitosis RNA Pol I transcription ceases and rRNA genes specifically reside at the short arm of the acrocentric chromosomes to form a structure called Nucleolar Organizer
Regions (NORs Fig.
According with Mariano & Delabie (2013) these complementary regions may indicate nucleolar organizer
regions, as has already been observed in other ants, such as Tapinoma nigerrimum (Lorite et al.
Giemsa staining, nucleolar organizer
region (NOR) banding, C-positive heterochromatin banding and DAPI fluorescence were used in N metaphases of a specimen collected in Asa Branca Farm, in Aurora do Tocantins municipality, Tocantins state, Brazil.
It was applied the conventional 2% Giemsa staining for 5 minutes to obtain chromosome measures and Ag-NOR banding according to Howell and Black (1980) for nucleolar organizer
regions (NOR) localization and also for counting the nucleolus number in interphase cells.
Correlation between histologic diagnosis mean nucleolar organizer
region count and prognosis in canine mammary tumors.
Chromosomal localization and activity of nucleolar organizer
regions in the dog (Canis familiaris).
