Azzopardi et al (4) in 1982, based on positive modified silver staining and demonstration of neuroendocrine secretory granules on electron microscopy, referred to these tumors as argyrophilic
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.
Spatial learning induces increasing of argyrophilic
nucleolar organizer region (AgNOR) of medial pallium neurons in toads (Rhinella arenarum).
sup] found low expression of the argyrophilic
nucleolar organizer regions and proliferating cell nuclear antigen activity was significantly correlated with the VDT of RCC.
fibers were stained by Foot method, and fibrin was stained by Shueninov.
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.
This may be due to replacement of fine argyrophilic
fibers which appeared early and subsequently replaced by coarse fibers of collagen which appeared during later stages of wound healing, thus resulting in decrease in reticulin amount.
2011) Multifocal granulomatous jejunitis associated with an argyrophilic
gram-positive segmented filamentous bacterium in a Holstein cow.
and Glucagon-Immunoreactive cells in the ileum and colon of the developing opossum Didelphis albiventris (Marsupialia).
The neuropathological diagnosis in the participants who did not meet pathological criteria for AD included dementia with Lewy bodies, hippocampal sclerosis, Parkinson's disease, subcortical microscopic infarct, mesial temporal lobe neurofibrillary tangles, neurofibrillary tangles with argyrophilic
grains and glial tauopathy, and no neuropathology," the authors wrote.
NFAs are seen in a number of brain regions in Al-treated aged and young rabbits.
