A small intestine sample stained using the Grocott's methenamine silver stain demonstrating histoplasma (black round yeast with narrow budding) in a granuloma In pathology , the Grocott–Gömöri's methenamine silver stain , abbreviated GMS , is a popular staining method in histology .
Due to its short staining time, Diff-Quik stain is often used for initial screening of cytopathology specimens. This staining technique allows the cytotechnologist or pathologist to quickly assess the adequacy of the specimen, identify possible neoplastic or inflammatory changes, and decide whether or not additional staining is required.

A handheld thermal imaging camera. A thermal imaging camera consists of five components: an optic system, detector, amplifier, signal processing, and display. [1] Fire-service specific thermal imaging cameras incorporate these components in a heat-resistant, [2] ruggedized, and waterproof housing. [3]
The Kinyoun method can be modified as a weak acid fast stain, which uses 0.5–1.0% sulfuric acid instead of hydrochloric acid.The weak acid fast stain, in addition to staining Mycobacteria, will also stain organisms that are not able to maintain the carbol fuchsin after decolorizing with HCl, such as Nocardia species and Cryptosporidium.
There are occasions when the type of components being treated, or their low production levels, require manual equipment operation. Under these conditions, a number of hazards peculiar to thermal spraying are experienced in addition to those commonly encountered in production or processing industries.
Another common variant is the Masson trichrome & Verhoeff stain, which combines the Masson trichrome stain and Verhoeff's stain. [2] This combination is useful for the examination of blood vessels ; the Verhoeff stain highlights elastin (black) and allows one to easily differentiate small arteries (which typically have at least two elastic ...
Trichrome stains are staining methods in which three anionic dyes are used, in conjunction with either phosphomolybdic acid (PMA), phosphotungstic acid (PTA), or a mixture of these heteropolyacids. Probably the first trichrome method was that of Frank B Mallory, an American pathologist, first published in 1900. [ 1 ]
Mallory's trichrome stain also called Mallory's Triple Stain is a stain utilized in histology to aid in revealing different macromolecules that make up the cell. It uses the three stains: aniline blue, acid fuchsin, and orange G. As a result, this staining technique can reveal collagen, ordinary cytoplasm, and red blood cells. It is used in ...
