Thermus and the Pink Discoloration Defect in Cheese

A DNA sequencing-based strategy was applied to study the microbiology of Continental-type cheeses with a pink discoloration defect. The basis for this phenomenon has remained elusive, despite decades of research. The bacterial composition of cheese containing the defect was compared to that of control cheese using 16S rRNA gene and shotgun metagenomic sequencing as well as quantitative PCR (qPC...

Biochemical Studies of Rib Discoloration and Pink Rib of Lettuce

The resulting injury to specific cells of the leaves releases the contents of the vacuoles, allowing intermixing with enzymes associated with other cell structures. Phenol oxidase is such an enzyme and causes the oxidation of various polyphenols (tannin -like substances) normally found in the cell vacuole. Oxidation of polyphenols, followed by vaguely understood polymerization reactions, result...

A Case with Skin Discoloration

Erythema ab igne is a pigmented reticular skin lesion with telangiectasias caused by prolonged exposure to heat. In this report an 11-year-old adolescent boy with erythema ab igne induced by a laptop computer was discussed.

Thallium intoxication with metallic skin discoloration.

A 40-year-old woman was admitted to the hospital with painful paresthesias after drinking brandy and red wine containing thallium. A severe acute axonal sensorimotor neuropathy was diagnosed. She rapidly deteriorated and became comatose within less than a week.1 Metallic skin discoloration and darkening of the cheek and chin areas was observed (figure). Two weeks after thallium ingestion patchy...
