New research: Danish nasal filter more than halves symptoms of hay fever

Clinical trials carried out by Aarhus University show that the use of a mini filter prevents pollen inhalation and results in significantly fewer symptoms such as sneezing, watery eyes and drowsiness

New research: Danish nasal filter more than halves symptoms of hay fever
2015-06-09
(Press-News.org) Getting through the pollen season can now become easier for some of the approximately 500 million people worldwide who suffer from sneezing and a runny nose, watery eyes and drowsiness during the allergy season (seasonal allergic rhinitis). This is indicated by a controlled trial carried out by researchers from Aarhus University. The trial, which took place over two days, included 65 people with grass pollen allergies who were not receiving any medical treatment at that time. They were either equipped with a nasal filter or a placebo device. The conclusion was that the filter was significantly more effective than the placebo - especially when it was used preventively: "The nasal filter more than halved a number of the most common symptoms such as sneezing, runny nose and watery eyes. And when participants initiated use of the filters before symptom onset, the effects were even more pronounced, which we see as an indication of the nasal filter's preventive effect," says professor Torben Sigsgaard from Aarhus University. Up to one hundred per cent effective Among the test subjects who initiated use of the filters before symptom onset, the study showed that e.g. sneezing and watery eyes were reduced by 100 per cent over the whole day, while runny noses were decreased by 84 per cent compared to the placebo. These symptom reductions when using nasal filters were greater than what had been shown in similar park studies regarding medical treatments. "Moreover, the subjects with nasal filters did not feel worse, even though the pollen levels on day two were markedly higher than those on day one. This suggests that the nasal filters will become increasingly beneficial as pollen levels increase," says the inventor of the filter, MD-PhD student Peter Sinkjaer Kenney from Aarhus University. The filters also reduced drowsiness Another significant result is that the nasal filters appeared to reduce drowsiness with more than 50 per cent compared to the placebo: "This is interesting because drowsiness is a well-known side-effect of some of the most frequently used antihistamines, and for some, having allergy can in itself result in tiredness. So for some allergy sufferers, this could perhaps turn out to be the most important benefit of the filter," says Torben Sigsgaard. The study has just been presented at The 2015 Annual Congress of the European Academy of Allergy and Clinical Immunology, EAACI, in Barcelona and will shortly be published in the Journal of Allergy and Clinical Immunology. In addition, the researchers are working on publishing the results of a large usability study with 1,073 participants, where a significant share of the participants found the filter to be sufficiently comfortable to be used daily during the hay fever season. This study was also presented at the congress in Barcelona.

Researchers identify unique marker on moms chromosomes in early embryo
2015-06-09
Athens, Ga. - Researchers in the University of Georgia's Regenerative Bioscience Center are visually capturing the first process of chromosome alignment and separation at the beginning of mouse development. The findings could lead to answers to questions concerning the mechanisms leading to birth defects and chromosome instability in cancer cells. "We've generated a model that is unique in the world," said Rabindranath De La Fuente, an associate professor in the UGA College of Veterinary Medicine. "Because we removed ATRX protein expression only in the oocyte, the female ...

Land management practices to become important as biofuels use grows

2015-06-09
The handling of agricultural crop residues appears to have a large impact on soil's ability to retain carbon, making land management practices increasingly important, especially under a scenario where cellulosic materials become more heavily used as a feedstock for ethanol production, according to a recently published study led by researchers at the U.S. Department of Energy's Argonne National Laboratory. "Plants and soil are carbon sinks," said Argonne climate scientist Beth Drewniak, who led the study. "Soils lock carbon away for long periods of time. But when plant ...

Just add water: Stanford engineers develop a computer that operates on water droplets

2015-06-09
Computers and water typically don't mix, but in Manu Prakash's lab, the two are one and the same. Prakash, an assistant professor of bioengineering at Stanford, and his students have built a synchronous computer that operates using the unique physics of moving water droplets. The computer is nearly a decade in the making, incubated from an idea that struck Prakash when he was a graduate student. The work combines his expertise in manipulating droplet fluid dynamics with a fundamental element of computer science - an operating clock. "In this work, we finally demonstrate ...
