CD208 DC lysosomal-associated protein is a marker of activated human dendritic cells; however, recently it was described as a marker of adult type II pneumocytes in many species including humans and sheep. Our hypothesis was that CD208 is developmentally regulated in lung pneumocytes. Lamb lungs at varying stages of development were stained immunohistochemically for CD208 and with Nile red (a f...

BACKGROUND Detection of amyloid can be done by several techniques either histochemical or immunohistochemical. Among them, one of the less mentioned in texts of reference and in reports on amyloidosis, is the examination with ultraviolet light of the stain of Congo red. We intend to examine cases of amyloidosis stained with Congo red with ultraviolet light and to see if such method offers advan...

Background & Objectives: Oral submucous fibrosis (OSMF) is a condition where excessive deposition of dense collagen fibers occurred in the connective tissue of oral mucosa. An alteration of collagen necessitates an in depth understanding of collagen in oral tissues as no breakthrough studies have been reported. Therefore the aim was to correlate the clinical, functional and histopathol...

Fuchsine acid is one of the supramolecular dyes used in Masson’s trichrome stain and has enormous applications histology. It also Van Gieson’s method with picric to show red collagen fibers smooth muscle contrast collagen. In addition these, it several other important electronic fields photonic devices as an organic semiconductor. Therefore, utmost importance investigate predict complex molecul...

Virtual stain transfer is a promising area of research in Computational Pathology, which has great potential to alleviate important limitations when applying deep-learning-based solutions such as lack annotations and sensitivity domain shift. However, the literature, majority virtual staining approaches are trained for specific or combination, their extension unseen stainings requires acquisiti...

OBJECTIVE To screen for amyloid and to assess associated clinical and laboratory characteristics in Egyptian patients with rheumatoid arthritis (RA). METHODS Abdominal subcutaneous fat aspirates were consecutively collected from 112 patients (103 women, nine men) having RA for five years or more. To detect amyloid, fat smears were stained with Congo red and the concentration of amyloid A prot...
