A new finding of a link between an anxiety disorder and peptic ulcer disease lends support to the view that this gastrointestinal disease and anxiety disorder may share a common link. In recent years, attention has focused on a more biological element with the identification of bacteria as a cause of peptic ulcers.
"The identification of Helicobacter pylori as an infectious cause of peptic ulcer disease has been considered by many to disprove the possibility that there is an important relationship between anxiety disorders and gastrointestinal disease," says study author Renee D. Goodwin, Ph.D., from the Department of Epidemiology at the Mailman School of Public Health at Columbia University in New York City.
"Over the last several years research on the causes and treatments for peptic ulcer disease has neglected the links with psychiatric/psychological factors," she notes.

A novel mechanism for electron optics in two-dimensional solid-state systems opens up a route to engineering quantum-optical phenomena in a variety of materials
Electrons can interfere in the same manner as water, acoustical or light waves do. When exploited in solid-state materials, such effects promise novel...
Biochemists at Martin Luther University Halle-Wittenberg (MLU) have used a standard electron cryo-microscope to achieve surprisingly good images that are on par with those taken by far more sophisticated equipment. They have succeeded in determining the structure of ferritin almost at the atomic level. Their results were published in the journal "PLOS ONE".
Electron cryo-microscopy has become increasingly important in recent years, especially in shedding light on protein structures. The developers of the new...
New insight into the spin behavior in an exotic state of matter puts us closer to next-generation spintronic devices
Aside from the deep understanding of the natural world that quantum physics theory offers, scientists worldwide are working tirelessly to bring forth a...
Kiel physics team observed extremely fast electronic changes in real time in a special material class
In physics, they are currently the subject of intensive research; in electronics, they could enable completely new functions. So-called topological materials...
Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
