Scientists link iron deficiency to Third World brain crisis

08.07.2005


SCIENTISTS at Manchester Metropolitan University have begun ground-breaking research to combat an alarming rise in brain damage in children living in the world’s most polluted countries.



Biomedical researchers in the city are investigating a link between poor diet in young children and neurological damage caused by polluted air and water and poisonous consumer products.

If a link is proven, a simple course of supplements could prevent irreversible brain damage in thousands of children in Asia, Latin America and Eastern Europe and prevent many more from suffering reduced IQs.


Pakistan, where the study will begin, has the worst lead pollution in the world, with 80% of children having levels of lead in their bloodstream that are detrimental to intelligence.

Dr Nessar Ahmed, of MMU’s Department of Biological Sciences, said: “In the same districts, studies show that 65% of children aged 7-60 months have iron deficiency.

“If we can prove that such deficits lead to high levels of metal absorption into the bloodstream, that will be highly significant in terms of preventing growing levels of brain damage associated with polluted environments.”

Dr Ahmed and the MMU team, in partnership with the Dr Panjwani Centre for Molecular Medicine and Drug Research, University of Karachi, will study 200 Pakistani children with differing levels of iron deficiency, testing their blood and hair for lead and manganese.

Hair samples will be flown back to Manchester where they will be tested for metal content at the Faculty of Science and Engineering Analytical Centre, a high-tech facility for identification of trace substances.

Added Dr Ahmed: “We expect our first findings in summer 2006 and if our hypothesis is correct, the results should reinforce the importance of not only reducing lead and manganese pollution, but also the development of national health strategies to cut childhood iron deficiency.”

The study, funded by the Nestle Foundation, is the only UK based research sponsored by the Foundation in 2004/5.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
