Agents that alter blood levels of beta-amyloid protein in mouse models of Alzheimers disease represent a potential approach to treating the illness in humans that may be safer than the vaccine method of therapy, researchers report in a new study.
Beta-amyloid protein is a component of the amyloid plaques that accumulate in the brains of people with Alzheimer¡s disease. Beta-amyloid is viewed by many researchers and clinicians as the underlying cause of the degeneration and dementia that characterize the illness. Alzheimers disease is a progressive, degenerative brain disease and the most common form of dementia. There is no cure. Approximately four million Americans have the disease and some 14 million are expected to have it by 2050 unless a cure or preventive treatment is found.
"Recent evidence suggests that this protein in the peripheral circulation outside the brain may contribute to its accumulation in the brain," says study co-author Karen Duff, PhD, of the Center for Dementia Research, Nathan Kline Institute/New York University. The study, funded by the National Institutes of Health and the Alzheimers Association, appears in the January 1 issue of The Journal of Neuroscience.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
