A Review on the Bulk and Surface Chemistry of Iron in Atmospherically-relevant Systems Containing Humic Like Substances (HULIS) [PDF]

open access: yes, 2015
As the fourth most abundant element by mass in the Earth’s crust, iron is ubiquitous and its chemistry is rich and interdisciplinary in nature. This review synthesizes the current state of knowledge of iron chemistry in multicomponent atmospheric ...

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

open access: yesPLoS 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.

A MFS-like plasma membrane transporter required for Leishmania virulence protects the parasites from iron toxicity.

open access: yesPLoS Pathogens, 2018
Iron is essential for many cellular processes, but can generate highly toxic hydroxyl radicals in the presence of oxygen. Therefore, intracellular iron accumulation must be tightly regulated, by balancing uptake with storage or export.

Studies on plants that hyperaccumulate copper, cobalt and nickel : their potential for use in phytomining and phytoremediation : a thesis presented in partial fulfillment of the requirements for the degree of Masterate of Science in Soil Science at Massey University [PDF]

open access: yes, 1998
This thesis reviews three lines of research on hyperaccumulators to examine their potential for phytoremediation and phytomining. The first line of research was to test the affect of nutrient addition on biomass and nickel uptake by two nickel ...

The vertical distribution of iron stable isotopes in the North Atlantic near Bermuda [PDF]

open access: yes, 2012
Seawater dissolved iron isotope ratios (δ^(56)Fe) have been measured in the North Atlantic near Bermuda. In a full-depth profile, seawater dissolved δ^(56)Fe is isotopically heavy compared to crustal values throughout the water column (δ^(56)Fe_(IRMM-014)

Impairment of interrelated iron- and copper homeostatic mechanisms in brain contributes to the pathogenesis of neurodegenerative disorders

open access: yesFrontiers in Pharmacology, 2012
Iron and copper are important co-factors for a number of enzymes in the brain, including enzymes involved in neurotransmitter synthesis and myelin formation. Both shortage and an excess of iron or copper will affect the brain.

Hyperthermia treatment of tumors by mesenchymal stem cell-delivered superparamagnetic iron oxide nanoparticles. [PDF]

open access: yes, 2015
Magnetic hyperthermia - a potential cancer treatment in which superparamagnetic iron oxide nanoparticles (SPIONs) are made to resonantly respond to an alternating magnetic field (AMF) and thereby produce heat - is of significant current interest. We have

Transferrin as a source of iron for Campylobacter rectus

open access: yesJournal of Oral Microbiology, 2011
Background and Objective: Campylobacter rectus is considered as one of the bacterial species of etiological importance in periodontitis. Iron-containing proteins such as transferrin are found in periodontal sites and may serve as a source of iron for ...

The use of the Ussing chamber system to investigate iron absorption by the duodenum, jejunum and ileum in the mouse : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Physiology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2002
Iron deficiency anaemia is found in approximately 30% of the worlds population and is particularly prevalent in developing countries. The majority of these deficiencies are due to insufficient absorption of iron from the diet.

Milk osteopontin has high iron-binding capacity and facilitates iron absorption in intestinal cells

open access: yesJournal of Dairy Science
: Insufficient absorption of iron and the consequent development of iron deficiency have serious health consequences. Hence, identification and development of iron delivery systems that can increase the bioavailability and uptake of dietary iron are ...
