Some 37 million Americans suffer from sinusitis; some of those patients are unfortunate enough to also have asthma, an inflammatory disease of the lungs characterized by reversible airway obstruction. The Centers for Disease Control (CDC) estimates that more than 15 million Americans have this disorder. The association between asthma and rhinosinusitis has long been established. While this relationship is unclear, molecular research is now focusing on whether asthma and rhinosinusitis are likely upper and lower airway manifestations of the same mucosal inflammation.
As a whole, sinusitis in asthmatics tends to be more severe and resistant to medical treatment. A new study set out to the incidence of specific rhinosinusitis symptoms in asthmatics versus non-asthmatics. This entailed identifying the differences in sinusitis symptoms experienced by asthmatics versus non-asthmatics, evaluating the failure of prescription medications for treatment, and specifying and comparing the surgical treatment need.
The authors of “The Incidence and the Effect of Asthma on Consecutive Patients with Chronic Rhinosinusitis,” are Melanie W. Seybt MD, Kevin C. McMains MD, and Stilianos E. Kountakis MD PhD, all with the Department of Otolaryngology-Head and Neck Surgery, Medical College of Georgia, Augusta, GA. Their findings are being presented at the American Academy of Otolaryngology-Head and Neck Surgery Foundation Annual Meeting & OTO EXPO, being held September 19-22, 2004, at the Jacob K. Javits Convention Center, New York City, NY.

Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
