Zinc and Copper Differentially Modulate Amyloid Precursor Protein Processing by -Secretase and Amyloid- Peptide Production

Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Guillermo Miguel Garcia Osuna

Recent evidence suggests involvement of biometal homeostasis in the pathological mechanisms in Alzheimer's disease (AD). For example, increased intracellular copper or zinc has been linked to a reduction in secreted levels of the AD-causing amyloid- peptid ...

Low-energy biomarker detection through charge-based impedance measurements

Mihai Adrian Ionescu, Junrui Zhang, Marco Mazza

A novel approach for the detection of biomarkers in aqueous condition via differential impedance is presented. The binding of biomarkers onto functionalized inter-digital electrodes induces a change in the sensor impedance, both in its real and imaginary c ...

Performance of Serum microRNAs-122,-192 and-21 as Biomarkers in Patients with Non-Alcoholic Steatohepatitis

Christian Hammer

Objectives Liver biopsies are the current gold standard in non-alcoholic steatohepatitis (NASH) diagnosis. Their invasive nature, however, still carries an increased risk for patients' health. The development of non-invasive diagnostic tools to differentia ...

A 1024-sample serum analyzer chip for cancer diagnostics

Sebastian Maerkl, Jose Luis Garcia Cordero

We present a platform that combines microarrays and microfluidic techniques to measure four protein biomarkers in 1024 serum samples for a total of 4096 assays per device. Detection is based on a surface fluorescence sandwich immunoassay with a limit of de ...

Differential X-ray phase contrast tomography of Alzheimer plaques in mouse models: perspectives for drug development and clinical imaging techniques

Peter Modregger, Marco Stampanoni

Alzheimer's disease (AD) is a looming threat on an ever-ageing population, with devastating effects on the human intellect. A particular characteristic lesion - the extracellular amyloid plaque - accumulates in the brain of AD patients during the course of ...

Microfluidic device for analysis of protein biomarkers using magnetic bead surface coverage detection

Martinus Gijs, Hüseyin Cumhur Tekin, Cynthia Scherz

We present a microfluidic device for on-chip analysis of low-concentration protein biomarkers. A new detection method, based on the magnetic capture of proteins via superparamagnetic beads and counting the surface coverage of the latter is presented. The p ...
