Researchers at Oxford University’s Wellcome Trust Centre for Human Genetics have located a variant form of a polynucleotide sequence in the MHC region of chromosome 6p and identified its association with an increased secretion of TNF. Potential applications for this discovery include the diagnosis of asthma in patients, or a predisposition to asthma, and a patients’ suitability for treatment with anti-TNF therapy.
Asthma is a disease in which the airways become inflamed leading to blockage and narrowing, with resultant symptoms including wheezing, coughing, shortness of breath and tightening of the chest. Asthma sufferers can be of any race, age or sex, and over 17 million people in the United States alone suffer from the disease.
Most asthma is initiated by an IgE mediated allergy (atopy) to inhaled environmental allergens, including pollen, air pollutants and irritants. The susceptibility to asthma is strongly familial, and is due to both genetic and environmental factors. The identification of other genetic factors will lead to further understanding of susceptibility to asthma and an ability to develop a pharmacogenomic approach to treatment, new therapeutic approaches to treat sub-groups of patients who will benefit most from them. Tumour necrosis factor (TNF) is a potent pro-inflammatory cytokine that is found in increased concentrations in asthmatic airways and in lavage fluid from asthmatic lungs.

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.
