Observation of the distribution of Zn protoporphyrin IX (ZPP) in Parma ham by using purple LED and image analysis [PDF]
Meat Science, 2006 We investigated the distribution of Zn protoporphyrin IX (ZPP) in Parma ham by using purple LED light and image analysis in order to elucidate the mechanism of ZPP formation. Autofluorescence spectra of Parma ham revealed that ZPP was present in both lean meat and fat, while red emission other than that of ZPP was hardly detected.

Melatonin Analogues Potently Inhibit MAO-B and Protect PC12 Cells against Oxidative Stress
Antioxidants, 2021 Monoamine oxidase B (MAO-B) metabolizes dopamine and plays an important role in oxidative stress by altering the redox state of neuronal and glial cells. MAO-B inhibitors are a promising therapeutical approach for Parkinson’s disease (PD).

Establishment of a model experiment system to elucidate the mechanism by which Zn–protoporphyrin IX is formed in nitrite-free dry-cured ham [PDF]
Meat Science, 2004 The aim of this study was to establish a model experiment system to elucidate the mechanism by which Zn-protoporphyrin IX (ZPP) is formed in Parma ham. The established model consisted of myoglobin, meat and antibiotics, and incubation under anaerobic conditions resulted in a greater yield of ZPP.

Effects of Processing Temperature on Color Properties of Dry-Cured Hams Made without Nitrite
Foods, 2016 Dry cured hams were investigated for their ability to develop red color even at low temperature (3–4 °C) and in the absence of added nitrites; results were compared with those obtained from nitrite-free hams made at conventional warm maturing ...

Angewandte Chemie, Volume 138, Issue 27, 1 July 2026.A deep‐red‐excited osmium(II) photosensitizer (Os2) induces immunogenic cell death (ICD) under 740 nm irradiation and triggers robust anti‐tumor immune responses both in vitro and in vivo. ABSTRACT Immunogenic cell death (ICD), which converts tumor cells into their own vaccine, plays a pivotal role in the development of novel anticancer therapies. Here,
