A study appearing in an upcoming issue of the Journal of Alzheimer’s Disease, published by IOS Press, entitled "Quantitative proteomics of cerebrospinal fluid from patients with Alzheimer disease," may lead to a new test for diagnosing the devastating illness. About 4 million Americans suffer from Alzheimer’s disease, the most common form of dementia, characterized by memory loss and an inability to use language.
"The study identified 40 times more proteins in human spinal fluid than previously known," said Drs. Thomas Montine and Jing Zhang, co-authors of the study and neuropathologists at Harborview Medical Center and the University of Washington. Montine is a UW professor of neuropathology and Zhang is a UW assistant professor of pathology. "As a result, we hope to be able to develop a much more thorough and robust test for diagnosing and predicting the progression of Alzheimer’s disease," said Montine.
The study employed a proteomic method developed at the University of Washington and the Institute for Systems Biology in Seattle. It identified more than 400 proteins in human spinal fluid, up to 40 times more proteins than identified by previous research models. On average, one of every five proteins identified was substantially changed in patients with Alzheimer’s disease compared to older people without neurologic disease. This roster of changed proteins will serve as a platform to develop specific biomarker panels for Alzheimer’s disease and other geriatric dementias.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
