Age at Onset and Inflammatory Cells Define Patient Subsets, Guide Treatment
People who develop asthma as children may have a different disease than those who develop it as an adult. A study in the January issue of The Journal of Allergy and Clinical Immunology adds to the growing body of evidence that asthma is not a single disease, but a group of syndromes with different origins and biological characteristics. The research team, led by Sally Wenzel, M.D., a pulmonologist at National Jewish Medical and Research Center, also found that the absence or presence of inflammatory cells, called eosinophils, helped distinguish differences among asthma patients.
"We found that patients whose asthma began in childhood were more frequently allergic than those whose asthma began as adults, while adult-onset asthma was associated with more rapid loss of lung function," said Wenzel. "We were surprised to find that many patients showed no signs of inflammation, generally considered a hallmark of the asthma, yet they still had severe airflow limitation and many asthma symptoms."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
