Now, however, scientists from the Sahlgrenska Academy and the Department of Plant and Environmental Sciences at the University of Gothenburg have proven that the cellulose powder reduces symptoms of seasonal allergic rhinitis in children, without any adverse effects.
The powder is produced from pine trees and forms a barrier on the mucous membrane when puffed into the nose. This means that allergy causing substances are filtered out.
“The cellulose powder has no adverse effects, and this fact makes it a particularly attractive treatment for children. It is used increasingly in many countries, but there is until now no scientific study proving the efficacy of the cellulose powder in children during the pollen season”, is the comment from Nils Åberg, associate professor at the Department of Pediatrics and consultant at the Queen Silvia Children’s Hospital.
Therefore, a study was carried out at the Queen Silvia Children’s Hospital in Gothenburg during the birch pollen season in spring 2009. The cellulose powder was compared with a placebo (a substance without any medical effect). Fifty-three children and adolescents aged 8-18 years with allergic reaction to pollen participated in the study, lasting for 4 weeks when they puffed the powder in the nose3 times daily. Every day they also were on an antihistamine tablet (the most common treatment of hay fever). Reminders and reporting of symptom scores were performed using SMS messaging on mobile phones.
Pollen occurrence was measured every day on the roof of the hospital, and the pollen counts subsequently were analysed in relation to the symptoms reported by the children. Further data for the study came from previously unpublished statistics of pollen levels collected for 31 years at the same location in Gothenburg, from 1979 to 2009.
“We showed that the nasal symptoms of the children were significantly reduced in those who used the cellulose powder. The best effect was obtained at low to moderate concentrations of pollen, corresponding to the predominating levels in the area during the 31-year period. Furthermore, no adverse effects of the cellulose powder were seen”, Nils Åberg remarks. He concludes:
“The complete absence of adverse effects makes this treatment admirably suited to self-care, and particularly for the treatment of children. Controlled scientific studies such as the present also provide the healthcare system a basis for testing this product as a supplement to other treatments. It is often necessary to combine different agents, at least for parts of the pollen season.”HAY FEVER

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
