New Terrestrial Native Iron Discovered on Earth's Surface

Geochemistry, Geophysics, Geosystems
Native iron is a major common mineral in lunar samples and meteorites but rarely occurs on Earth's surface, as its stability requires highly reducing conditions with very low oxygen fugacity.

Identification of an iron–hepcidin complex [PDF]

, 2008
Following its identification as a liver-expressed antimicrobial peptide, the hepcidin peptide was later shown to be a key player in iron homoeostasis. It is now proposed to be the 'iron hormone' which, by interacting with the iron transporter ferroportin,

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora. [PDF]

FEBS Open Bio
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Improving growth properties of Corynebacterium glutamicum by implementing an iron‐responsive protocatechuate biosynthesis

Microbial Biotechnology, 2023
Corynebacterium glutamicum experiences a transient iron limitation during growth in minimal medium, which can be compensated by the external supplementation of protocatechuic acid (PCA). Although C. glutamicum is genetically equipped to form PCA from the

Native cardiac magnetic resonance T1 mapping and cardiac mechanics as assessed by speckle tracking echocardiography in patients with beta-thalassaemia major

International Journal of Cardiology: Heart & Vasculature, 2022
Background: We hypothesize that cardiac magnetic resonance (CMR) native T1 is associated with myocardial deformation in thalassaemia patients. The present study aimed to compare CMR native T1 values to conventional T2* values in patients with beta ...

Mineralogy and geochemistry of native iron

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Basite magmatism has been manifested repeatedly for a long time in various geodynamic structures within the eastern part of the Siberian platform. In the Middle Paleozoic, it was related to rifting processes, and in the Late Paleozoic-Early Mesozoic – to the initiation and development of trap syneclises.

Effect of Native American ancestry on iron-related phenotypes of Alabama hemochromatosis probands with HFE C282Y homozygosity

BMC Medical Genetics, 2006
Background In age-matched cohorts of screening study participants recruited from primary care clinics, mean serum transferrin saturation values were significantly lower and mean serum ferritin concentrations were significantly higher in Native Americans ...
