BACKGROUND Polybrominated diphenyl ethers (PBDEs) are persistent and bioaccumulative flame retardants, which are found in rising concentrations in human tissues. They are of concern for human health because animal studies have shown that they possess the potential to be developmentally neurotoxic. OBJECTIVE Because there is little knowledge of the effects(More)
Polybrominated diphenyl ethers (PBDEs) are bioaccumulating flame retardants found in rising concentrations in human tissue. Epidemiological and animal studies have raised concern for their potential to induce developmental neurotoxicity (DNT). Considering the essential role of calcium homeostasis in neurodevelopment, PBDE-induced disturbance of(More)
Based on complementary metal-oxide semiconductor (CMOS) technology a neurosensor chip with passive palladium electrodes was developed. The CMOS technology allows a high reproducibility of the sensors as well as miniaturization and the on-chip integration of electronics. Networks of primary neurones were taken from murine foetal spinal cord (day 14) and(More)
One possible cause for the neuronal loss in sporadic amyotrophic lateral sclerosis (S-ALS) is an increase of free radicals, which may produce oxidative damage to susceptible biomolecules, which, in turn, can damage the mitochondrial DNA (mtDNA). Following laser microdissection of single motor neurons from paraffin-embedded autopsy tissue, we analyzed the(More)
Mitochondrial dysfunction caused by mitochondrial DNA (mtDNA) aberrations has been implicated in the neuronal death in neurodegenerative disorders. Significant neuronal damage can occur if the percentage of mtDNA mutations may reach a critical threshold. mtDNA mutations also accumulate during normal aging. Here we quantified the 5 kB common mtDNA deletion(More)
