Congo red-negative amyloidosis-like glomerulopathy
Human Pathology, 1985Three cases of amyloidosis-like glomerulopathy are presented in which renal amyloidosis was initially diagnosed on the basis of ultrastructural findings, despite negative Congo red staining. The histologic and immunofluorescence findings and, on careful examination, ultrastructural features of this amyloidosis-like glomerulopathy all serve to ...

ACCORDING to Robinson and Mills1, “in general, the cotton substantive dyes cannot be recrystallized from water”. But some of the benzidine disazo dyes may with difficulty be recrystallized from alcohol–water mixtures2.

Elucidating the structure-activity relationship of curdlan is hampered by a lack of characterization with unique specific conformations (i.e., single- or triple-helix). In this study, single-helical curdlan is generated in dilute NaOH solutions at 35-50 °

Review on nickel-based adsorption materials for Congo red.
Journal of Hazardous Materials, 2020Excessive synthetic dyestuffs in the aquatic environment pose various ecological and health issues that are detrimental to sustainable development. Adsorption is considered a feasible technique of eliminating dye pollutants from the water environment ...

The Intracutaneous Congo Red Test
Acta Rheumatologica Scandinavica, 1960Summary The intracutaneous Congo Red test was studied in 30 subjects with the adult type of rheumatoid arthritis and in 24 patients with other collagen diseases. The rate of fading of the dye was compared with a control group of 40 subjects, some of whom were normal while the remainder suffered from a variety of general medical diseases.The fading rate

Diagnosis of amyloid beyond Congo red
Current Opinion in Nephrology & Hypertension, 2020Purpose of review Amyloidoses are a group of rare and heterogeneous diseases in which abnormally folded proteins deposit in tissues and lead to organ damage. A brief review of advances in the diagnosis of extracerebral systemic amyloidoses in the context of recent advances in their clinical management is provided.

Sonochemical degradation of Congo Red
International Journal of Environment and Waste Management, 2008Ultrasound irradiation was found to be effective in treatment of refractory pollutants. The present communication reports ultrasound treatment of Congo Red (CR). The CR degradation by ultrasonic waves (50 kHz) was investigated at 25?C. After sonication for 60 min, the CR concentration gradually decreased from 100 mg/L to 27.7 mg/L.

The congo red stain revisited.
Annals of clinical and laboratory science, 1989The Congo red stain has undergone several modifications since it was first used by Bennhold in 1922 in order to increase the specificity for staining amyloid. Most of the laboratories in the United States use the method of Puchtler which uses alkaline Congo red solution. Some of the variables associated with the procedure were investigated by us.
