Researchers are finding that components found in red wine can help in preventing and treating inflammatory periodontal diseases. Periodontitis is a progressive infectious disease affecting the gums and bone that surround and support teeth, often causing tooth movement and leading to permanent tooth loss. About 15% of adults between 21 and 50 years of age and 65% of adults over 50 are affected by this disease.
In recent years, the benefits of consuming fresh fruits and yellow-green vegetables and beverages, particularly green tea and red wine, have been reported to reduce human cancer incidence and mortality. The potential health benefits of those products are attributed to a broad range of compounds called polyphenols. Recent studies have also shown that red wine, and particularly grape seeds, possesses anti-inflammatory and anti-tumor activities and prevent heart disease. Mechanisms by which these phenolic compounds exert their protective effects include their anti-oxidant properties.
Scientists from Université Laval (Québec, Canada), reporting today at the 35th Annual Meeting of the American Association for Dental Research, conducted a study to investigate the role of polyphenols, including those from red wine, in scavenging free radicals released by immune cells stimulated with components of bacteria causing periodontal diseases. Because free radicals are generated by immune cells during periodontitis, it is critical to keep them at low levels to maintain healthy gums. Their results indicated that red wine polyphenols significantly modulate several inflammatory components released by macrophages (a population of host immune cells) in response to bacterial stimuli. Specifically, polyphenols efficiently scavenged and inhibited free-radical generation by host immune cells by controlling intracellular proteins involved in their release. These anti-oxidant properties of red wine polyphenols could be useful in the prevention and treatment of inflammatory periodontal diseases as well as other disorders involving free radicals.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
