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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
