Foods, 2022 The nitrosyl–heme complex is considered the pigment responsible for the development of reddish colour in cooked hams. However, the same reddish colour was observed in a nitrite-free product elaborated with polyphenols, suggesting the presence of other red pigments that can contribute to generate this colour.

Comparative Analysis of 5-ALA and Fluorescent Techniques in High-Grade Glioma Treatment
BiomedicinesBackground: 5-Aminolevulinic acid (5-ALA) serves as a precursor in the heme biosynthesis pathway, resulting in the selective accumulation of protoporphyrin IX (PpIX) within glioma cells.

Liver transplantation for acute-on-chronic liver failure from erythropoietic protoporphyria [PDF]
Clinical and Molecular Hepatology, 2012 Erythropoietic protoporphyria (EPP) is an inherited disorder of the heme metabolic pathway that is characterized by accumulation of protoporphyrin in the blood, erythrocytes, and tissues, and cutaneous manifestations of photosensitivity, all resulting ...

Butafenacil: A positive control for identifying anemia- and variegate porphyria-inducing chemicals
Toxicology Reports, 2015 Butafenacil is an herbicide that inhibits protoporphyrinogen oxidase (PPOX), an enzyme that catalyzes oxidation of protoporphyrinogen IX to protoporphyrin IX during chlorophyll and heme biosynthesis.

Thermoelectric Properties of Composite Nanoparticle Array with Protoporphyrin Molecule Junctions
MATEC Web of Conferences, 2017 Composite nano-structures have many interesting properties and potential applications. For a molecule-nanoparticle (NP) composite array, its properties may strongly depend on the molecules on/between NPs. For instance, the resistance of NP composite film

Experiments with Protoporphyrin
Experimental Biology and Medicine, 1946 Summary1. A simple method for the preparation of protoporphyrin from blood is described. 2. White rats were injected subcutaneously with protoporphyrin and were found to excrete greatly increased amounts of protoporphyrin in the feces. No urinary protoporphyrin nor increase of urinary coproporphyrin excretion following the injection was noted.

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents
Advanced Functional Materials, EarlyView.Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...
