Between 5% and 15% of people experience persistent infection of the nasal passages (chronic rhinosinusitis). Many homoeopathic and yogic forms of healthcare recommend spraying saline into the nose to relieve symptoms, and it is now often recommended as part of a programme of treatment in conventional medicine.
A team of Cochrane Researchers considered the data presented in eight separate randomised trials and 16 other studies, involving a total of 1659 patients, that examined the potential benefits of saline irrigation.
“While there is no evidence that saline is a replacement for standard therapies, spraying or irrigating saline into the nose is likely to improve symptoms for people with persistent infections,” says lead researcher Dr Richard Harvey who works at the University of Oxford and Royal National Throat Nose and Ear Hospital in London.
No one is really sure why saline reduces symptoms, but it could be because it softens mucus, making it easier to remove. The tiny hair-like process (cilia) that cover the surfaces of cells in the nose often fail to function properly and can’t beat to remove mucus, so the saline may help these cilia to work more efficiently. In addition, saline may simply help wash bacteria, viruses and allergic materials out of the nose.
“Doctors should consider recommending saline therapy as an adjunct for managing the symptoms of chronic rhinosinusitis,” says Harvey.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
