Abstract:
Nicholas Papanicolaou developed the Pap stain, a combination of three major stains used for cervical smears. Eosin-Azure (EA50), one of these stains, includes Eosin Y, Light Green SF, and Bismarck brown. This study explores the use of Curcuma longa extract as a substitute for Eosin Y in EA50. Cervical smears from premenopausal women were collected and stained using both the standard Papanicolaou stain and a modified version where Eosin Y was replaced with Curcuma longa extract. The modified stain's effectiveness was assessed based on the quality of staining of superficial cells. The modified s

Abstract:
Abstract Introduction: Brightfield histopathology uses chromogenic staining to assign distinct colors to different specimen elements. Multiplexing biomarker staining on the same slide has valuable advantages, including the ability to capture the spatial distribution of different cell populations and tissue structures. Color separation is a computational method that separates contributions from each chromogen. It enables the analysis of individual stain expressions, and serves as a crucial preprocessing step in numerous histopathology image analysis tasks (e.g. nuclear segmentation, stain norma

A wide variety of stains are useful for detection of different organisms or, for viruses, the cytopathologic changes they induce, in smears prepared directly from clinical specimens and in tissue sections.

Abstract:
The purpose of this research study was to test and subsequently validate a method based on the identification of biological fluids by nondestructive analysis, attributing phenotypic characteristics to biological stains. Specifically, a new methodology for non-destructive forensic histological analysis using Alternative Light Source 450 nm + orange filters was developed and validated - also testing its analytical efficiency and inherent degree of probabilistic error. The validation process has been carried out through the creation of a standard database of known samples, in which were included

Abstract:
Fabric plays a key role in modern society, used widely in fashion and home decor. Different fabrics, including synthetics like polyester, have unique properties that determine their applications. Stains, caused by foreign substances, are categorized into four types: enzymatic, oxidizable, greasy, and particulate. Stain removal often involves chemical-based products, which can be harmful. This study shows that Lemon Peel Extract (Citrus Limon L.) can remove oxidizable and particulate stains. With titrimetric and colorimetric analysis, it was found that 54.83% of particulate and 54.14% of oxidiz

Abstract Polymers find widespread use in blends, graft copolymers, polymer alloys, and composites. Staining is an important tool for microscopically visualizing polymer phases and morphologies in these multi-component systems. Three stains have been used in most investigations. These stains (and the functional groups they are aimed at) are: osmium tetroxide for chemical unsaturation; ruthenium tetroxide for styrenics; and phosphotungstic acid for polyamides. Beyond these three basic stains there are a significant number of additional ones that have been developed for special cases. Aside from

Introduction: Rapid on-site evaluation is commonly performed by pathologists to check for cellular adequacy of fine needle aspirate smears to reduce hospital visits of patients and to make preliminary diagnosis. For rapid evaluation, laboratories use Romanowsky stain, Hematoxylin and Eosin stain, supravital stains and ultra-fast Papanicolaou stain. The aim of the study is to evaluate fine needle aspirate smears on-site for sample adequacy using supravital stain Brilliant Cresyl Blue (BCB), to make preliminary cytological diagnosis and to compare with the routine cytological Papanicolaou stain

Extraction of feather defects is difficult because of their complicated and diversified characteristics. It is proposed that feather stain defects be extracted in HSI color space according to color characters of different types of feather defects. The improved variational level set method is adopted to locate and segment the feather stains on that basis. Experiment results show that the proposed methods can extract feather stains effectively and segment them accurately.

Another stain for Gram(-), as well as Gram(+), bacteria is a variation of the Gram stain.
