Researchers from the University of Chihuahua in Mexico report that immune systems of patients with asthma responded differently to a common laboratory challenge, depending on whether their white blood cells had been obtained during a time when they were suffering from common season allergic rhinitis or when they were free of such allergic symptoms.
The study was presented by Dr. Irene Leal-Berumen on Saturday, April 2, at The American Association of Immunologists scientific sessions during Experimental Biology 2005 in San Diego. She says the findings are an important first step to personalizing treatments for allergy and asthma, both worldwide diseases that interfere with life quality and generate high economic burden.
Asthma is a chronic obstructive inflammatory lung disease with symptoms including wheezing, coughing, chest tightness, and shortness of breath. Asthma attacks can be triggered by viral upper respiratory infections, exercise, extreme temperature condition, and chemical irritants – and also by the same allergens that cause seasonal allergies to pollen or mold spore or perennial allergies to dust mites, cockroaches, feathers, animal fur and other allergens. In fact, the vast majority of patients with asthma also experience one or both of these forms of allergy, with the same symptoms of frequent sneezing, itchy eyes, runny nose and nasal stuffiness.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
