Researchers say that zinc protoporphyrin (ZPP) could be a useful measure for screening infants from low-income families for iron deficiency (ID), as well as for monitoring response to therapy, ...

Offspring of diabetes patients may suffer from tissue iron deficiency. Erythrocyte zinc protoporphyrin/heme (ZnPP/H) ratios measure impaired iron status. The aim of the study was to examine whether ...

Erythropoietic protoporphyria and X-linked protoporphyria are inborn errors of heme biosynthesis that cause elevated circulating levels of metal-free protoporphyrin and phototoxicity. Both disorders ...

In the surgical treatment of cancer, distinguishing between tumors and healthy tissues is critical. Fluorescent markers can help to do this, by enhancing the contrast of tumors during surgery. Some ...

Sideroblastic anemia was found in an elderly man in association with dermal photosensitivity, a greatly increased erythrocyte free protoporphyrin content and reduced erythrocyte catalase activity.
