The progress of Parkinsons disease (PD), or any brain-wasting disease, is painful to watch in oneself or in a loved one. Physicians and researchers are not immune to that pain, but they watch the progression of disease with an eye toward understanding it and, one day, halting or reversing it.
Johannes Schwarz, M.D., and a team of researchers from Germany and Canada reported in the October issue of The Journal of Nuclear Medicine on a study that measured the molecular changes in the brains of PD patients over a 7.5-year time span that began during the early stages of the disease. The study used single photon emission computed tomography (SPECT) to image the loss of dopamine transporter binding. (While the pathology of Parkinsons disease is not completely understood, it is widely believed that the diseases progression is marked by a decline in dopamine transporter binding, part of the brains neurotransmitter circulation system.)
The study demonstrates that it is possible to measure, quantitatively and over a significant period of time, the molecular changes that take place in the brain as it undergoes progressive deterioration.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
