Jean-Bosco Ouedraogo of the Institut de Recherche en Sciences de la Santé (IRSS) in Bobo Dioulasso, Burkina Faso, and colleagues explain that vitamin A and zinc play a critical role in the normal function of the immune system, and may even play a synergistic role for reducing the risk of infection including malaria caused by Plasmodium falciparum.
There are approximately 300 to 500 million new cases of malaria each year across the globe, primarily due to P. falciparum.,The vast majority of cases occur in sub-Saharan Africa and lead to the death o f about one million children each year. Emerging drug resistance and ineffective insecticides used in malaria control have hampered efforts to reduce these figures. Moreover, people living in malaria-endemic areas often suffer from malnutrition and deficiencies of micronutrients such as vitamin A and zinc, which have serious health consequences.
In order to understand how reducing micronutrient deficiencies might influence malaria incidence, the researchers undertook a trial with a single dose of 200,000 IU of vitamin A and daily 10 mg of zinc supplementation in children aged 6 to 72 months in the village of Sourkoudougou in Burkina Faso. Half were given placebo. They evaluated the children daily for signs of fever and analyzed blood samples for the presence of the malaria parasite in those children with fever.
The researchers found a significant effect of vitamin A and zinc supplementation on malaria incidence. "At the end of the study we observed a significant decrease in the prevalence malaria in the supplemented group (34%) compared to the placebo group (3.5%)," they explained. Supplementation also increased the time to onset of malarial symptoms and reduced the frequency of episodes. "Supplementation thus may play a key role in malaria control strategies for children in Africa," they added.

On the way to developing a new active ingredient against chronic infections

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
