Current methods to diagnose Alzheimer´s Disease (AD) comprise computer tomography (CT), magnet resonance imaging (MRI) or positron emission tomography (PET) visualizing abnormalities in the brain. Other approaches concerns to the determination of biomarkers such as tau/ phospho-tau or beta Amyloid in body fluids (blood, liquor). However, CSF level of tau is a general marker for neuronal dysfunction and not specific for AD alone (also increased in Creutzfeldt Jacob). In AD patients, decreased levels of Abeta42 could be shown, however the values of concentrations in various AD patients differ dramatically so that Abeta42 alone is not a sufficient reliable marker. Furthermore Abeta42 seems to be decreased only in patients who already have clinical symptoms of AD. It is a strong medical need for diagnostic markers which are able to predict AD at a very early stage before clinical symptoms occur. This would allow earlier treatments before neuronal damage starts. <br><br> <strong>Technology</strong><br> We offer a novel approach for the early recognition of pre-symptomatic stages of AD even 20-30 years before clinical changes/ symptoms like mild cognitive impairment (MCI) or AD occur. The assay is based on the detection of the Aß38:Aß42 concentration ratio. A decrease of the Aß38:Aß42 ratio (value <1,5) in a phenotypically healthy, pre-symptomatic person is hypothized to be indicative that this person will develop MCI and AD later in life. This statement is based on findings in the human neuroblastoma cell line SHSY5Y stably expressing APP by investigating the expression and procession of AAP and is further based on postulating a gamma-secretase cleavage mechanism of APP-TMS (TM: transmembrane).<br><br>

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
