Determination of selected protoporphyrins in Parma ham with use of 5,10,15,20-tetra(4-hydroxyphenyl)porphyrin as a surrogate standard in the recovery study

open access: yesActa Chimica Slovenica, 2014
A high-performance liquid chromatographic analysis for the determination of hemin, protoporphyrin IX (PPIX), and zinc(II)protoporphyrin IX (Zn(II)PPIX) in Parmaham was developed.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Protoporphyrin IX copolymer with poly(Ethylene glycol) methacrylate and its thermoresponsive properties [PDF]

open access: yes, 2020
Porphyrins and their derivatives have been widely used in catalysis, energy conversion, photonics, and biomedicine; however, their use in biological applications is restricted by their limited solubility in aqueous systems.

Inherited microcytic anemias due to disorders of iron and heme metabolism: An updated clinical review

open access: yesHemaSphere, Volume 10, Issue 9, September 2026.
Abstract Microcytic anemia is among the most common hematological abnormalities in clinical practice and is usually attributable to iron deficiency, thalassemia traits, or anemia of inflammation. A small but clinically important subset of patients, however, has inherited disorders of iron metabolism or heme synthesis presenting with persistent ...

Mechanisms of Vesicular Stomatitis Virus Inactivation by Protoporphyrin IX, Zinc-Protoporphyrin IX, and Mesoporphyrin IX

open access: yes, 2017
Virus resistance to antiviral therapies is an increasing concern that makes the development of broad-spectrum antiviral drugs urgent. Targeting of the viral envelope, a component shared by a large number of viruses, emerges as a promising strategy to ...

GmDOF3.1‐GmCPX Module Regulates Nodulation and Nitrogen Fixation Abilities in Soybean

open access: yesPlant Biotechnology Journal, Volume 24, Issue 9, Page 5041-5058, September 2026.
ABSTRACT Soybean nodule nitrogen fixation is very important, which can provide a large amount of nitrogen supply for its own growth and that of other crops, but the mechanism is largely unclear. In the present study, a coproporphyrinogen oxidase gene, GmCPX, was identified to facilitate soybean nodulation and nitrogen‐fixation under the regulation of ...

G‐Quadruplexes: Structural Diversity and Emerging Roles in Biomolecular Condensation

open access: yesAdvanced Science, Volume 13, Issue 45, 13 August 2026.
G‐quadruplexes (G4s) fold into diverse intra‐ and intermolecular structures, positioning them as emerging regulators of biomolecular condensation. Mechanistically, G4s autonomously form condensates, act as structural platforms to initiate and stimulate condensation, or induce phase transitions.

Isothiocyanates as Ferroptosis Inducers to Promote Cancer Cell Death

open access: yesPhytotherapy Research, Volume 40, Issue 8, Page 5119-5131, August 2026.
ABSTRACT Cancer remains a leading cause of global mortality, with the therapeutic efficacy of anticancer drugs often hampered by late diagnosis and the development of chemotherapy resistance. Ferroptosis is an iron‐dependent form of regulated non‐apoptotic cell death driven by lipid peroxidation.

Ruthenium(II) and Osmium(II) Probes Based on the BODIPY Fluorophore for the Detection of Carbon Monoxide and Viscosity in Biological Environments

open access: yesAdvanced Sensor Research, Volume 5, Issue 7, July 2026.
Ruthenium and osmium vinyl complexes incorporating BODIPY fluorophores show highly selective, turn‐on detection of carbon monoxide (CO) in biological environments. Two different designs are compared and used to achieve sensitive in cellulo sensing of CO.
