In erythropoietic protoporphyria less than half the circulating erythrocytes fluoresce, but all erythrocytes hemolyze in vitro on exposure to 400 nanometer radiation. It was shown that 400 nanometer ...

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 ...

When the FDA approved the first treatment specifically for erythropoietic protoporphyria (EPP) in 2019, it was "really the first ray of hope." Before afamelanotide, "there was just a therapeutic ...

Despite present therapies of hypertransfusion and chelation of iron with desferrioxamine (DFO), patients with thalassemia major continue to succumb in their early to mid twenties to fatal iron ...

A lab worker wearing face mask, safety spectacles and hair net looks intently at a pipette Disc Medicine has repurposed a drug candidate originally developed for schizophrenia and pointed it squarely ...

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.

Most perching birds lay eggs speckled with reddish protoporphyrin spots toward the egg's blunt end. Evidence in a paper by Gosler, Higham & Reynolds soon to appear in <i>Ecology Letters</i> suggests ...

(a) Schematic of the liquid cell for XAS analysis of metal porphyrin complexes in aqueous solutions. XAS spectra of the central metals were obtained at the Fe or Co L 2,3-edge and those of ligands ...
