Amyloid precursor protein (APP) can be proteolytically processed along two pathways, the amyloidogenic that leads to the formation of the 40-42 amino acid long Alzheimer-associated amyloid β (Aβ) peptide and the non-amyloidogenic in which APP is cut in the middle of the Aβ domain thus precluding Aβ formation. Using immunoprecipitation and mass spectrometry(More)
BACE1 is a key enzyme for amyloid-β (Aβ) production, and an attractive therapeutic target in Alzheimer's disease (AD). Here we report that BACE1 inhibitors have distinct effects on neuronal Aβ metabolism, inducing a unique pattern of secreted Aβ peptides, analyzed in cell media from amyloid precursor protein (APP) transfected cells and in cerebrospinal(More)
Niemann-Pick type C (NPC) is a progressive neurodegenerative lysosomal disease with altered cellular lipid trafficking. The metabolism of amyloid-β (Aβ) - previously mainly studied in Alzheimer’s disease - has been suggested to be altered in NPC. Here we aimed to perform a detailed characterization of metabolic products from the amyloid precursor protein(More)
BACKGROUND Approximately 50% of children born with cleft palate present speech difficulties around 3 years of age, and several studies report on persisting phonological problems after palatal closure. However, studies on early phonology related to cleft palate are few and have so far mainly been carried out on English-speaking children. Studies on phonology(More)
We present a simple tool that enables the computer to read subtitles of movies and TV shows aloud. The tool extracts information from subtitle files, which can be freely downloaded from the Internet, and reads the text aloud through a speech synthesizer. There are three versions of the tool, one for Windows and Linux, another for Mac OS X, and the third is(More)
Much is unknown regarding the regulation of Alzheimer-related amyloid-beta protein precursor (AbetaPP)-processing in the human central nervous system. It has been hypothesized that amyloidogenic AbetaPP-processing preferentially occurs in the regulated secretory pathway of neurons. To test this hypothesis we looked for correlations of AbetaPP-derived(More)
The Sport Concussion Assessment Tool (SCAT) is a standardised global assessment for the identification of sport-related concussion (SRC). An integral component of the SCAT is the neurological screen, which contains the assessment of motor performance including gait evaluation. However, it is not known how performance of gait is affected by the(More)
The β-secretase enzyme, β-site amyloid precursor protein-cleaving enzyme 1 (BACE1), cleaves amyloid precursor protein (APP) in the first step in β-amyloid (Aβ) peptide production. Thus, BACE1 is a key target for candidate disease-modifying treatment of Alzheimer’s disease. In a previous exploratory Aβ biomarker study, we found that BACE1 inhibitor treatment(More)
Benzene was assessed as the predominant aromatic compound emitted from glowing charcoal and firewood embers. Concentrations measured above charcoal used for grilling exceeded 10 mg m(-3) at a 5% carbon dioxide level. Charcoal with a high carbon content released less benzene. Glowing wood pellets emitted less benzene than glowing firewood remainders. The(More)
