Markers that have been studied in the literature and that are not considered useful in the diagnosis of mesothelioma versus mesothelial hyperplasia include minichromosome maintenance 2 protein, telomerase transcriptase expression (which needs to be studied further), Ki-67, transforming growth factor, epidermal growth factor receptor, Bcl-2, and argyrophilic
nucleolar organizer region.
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.
The effects of both neurotoxicants on the argyrophilic
reaction at the different brain levels were compared with controls that consisted of fish maintained under conditions identical to those of the two treatment groups except that only vehicle was added to the tanks.
Histologically, lymph node aspirates are characterized by the presence of small, pleomorphic, gram-negative, argyrophilic
bacilli on Warthin-Starry staining.
3) They can arise from either argyrophilic
Kulchitsky's cells or pluripotential salivary stem cells.
Expression of topoisomerase IIa, Ki-67, proliferating cell nuclear antigen, p53, and argyrophilic
nucleolar organizer regions in vulvar squamous lesions.
49-58) In addition, the counting of silver-stained nucleolar organizer regions (AgNORs) (loops of DNA encoding ribosomal RNA that associate with argyrophilic
nonhistone proteins, which can be visualized with silver-staining) has been suggested as a method for the differential diagnosis of MM from benign reactive hyperplasia.
6) Data showing that LCC has higher argyrophilic
nucleolar organizer region values than other normal-looking hepatocytes (with the highest argyrophilic
nucleolar organizer region values being strongly associated with HCC development during follow-up), (17) abnormal DNA content, (18-20) chromosomal numerical aberrations, and chromosomal gains and losses (21,22) all demonstrate that LCC is a precancerous lesion.
Use of multiple cytometric markers improves discrimination between benign and malignant melanocytic lesions: a study of DNA microdensitometry, karyometry, argyrophilic
staining of nucleolar organizer regions and MIB1-Ki67 immunoreactivity.
As with neuroendocrine tumors from other sites, the cells are positive for argentaffin and argyrophilic
stains and show dense-core neurosecretory granules on ultrastructural examination.
Silver stain frequently demonstrates segmental duplication of peripheral capillary walls resulting from mesangial cell cytoplasm interposition, and it also highlights expanded mesangial areas, which appear argyrophilic
