Determination of 55Fe and 63Ni in Pb–Bi by Radiochemical Separation Method

Science and Technology of Nuclear Installations
This paper introduces a simple and rapid separation method for the determination of 55Fe and 63Ni in lead–bismuth alloys. This method is based on chemical precipitation and solid-phase extraction chromatography techniques, which can separate and purify ...

Identification of New Key Players for Ferrous Iron Export in the Asymmetric Inner Gate of Human Ferroportin 1. [PDF]

FASEB J
Ferroportin 1 is an iron exporter belonging to the Major Facilitator Superfamily. Its unusual intracellular gate is formed by asymmetric networks of non‐covalent bonds. We analyzed these networks using Molecular Dynamics simulations and experimental tests and identified novel amino acids as key players in inter‐lobe connections.

The cytochrome oxidase defect in ISC-depleted yeast is caused by impaired iron-sulfur cluster maturation of the mitoribosome assembly factor Rsm22. [PDF]

FEBS Lett
The yeast mitoribosome assembly factor Rsm22 contains a [4Fe‐4S] cluster that is matured by the mitochondrial iron–sulfur cluster assembly (ISC) machinery. Defects in ISC components result in impaired mitochondrial protein synthesis due to a mitoribosome assembly defect.

Fine Powder Proportional Counters for Neutron Detection

U.Porto Journal of Engineering, 2022
A novel neutron detection approach is presented, consisting of a neutron sensitive aerosol obtained by dispersing B4C fine powder in a gaseous proportional counter operating in continuous flow, which proved to effectively detect thermal neutrons.

The reduced genome of the Francisella tularensis live vaccine strain (LVS) encodes two iron acquisition systems essential for optimal growth and virulence.

PLoS ONE, 2014
Bacterial pathogens require multiple iron-specific acquisition systems for survival within the iron-limiting environment of the host. Francisella tularensis is a virulent intracellular pathogen that can replicate in multiple cell-types.
