The Chinese hamster ovary cell line 7PA2, stably transfected with the 751 amino acid isoform of amyloid-β protein precursor (AβPP) containing the Val → Phe mutation at residue 717, is one of the most used models to study the biochemistry and toxicity of secreted amyloid-β (Aβ) peptides, particularly Aβ oligomers, which are considered to be of relevance to(More)
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)
PURPOSE Approximately 600 teenagers and young adults, TYAs (ages 15-29), are newly diagnosed with cancer in Sweden every year and treated in many different units. The knowledge about TYAs is limited and there might be a need for a new approach in the care for this particular age group. The purpose of this study was to identify requirements TYAs in Sweden(More)
OBJECTIVE AND DESIGN This review of 88 articles in three international journals was undertaken for the purpose of investigating the methodology for perceptual speech assessment in patients with cleft palate. The articles were published between 1980 and 2000 in the Cleft Palate-Craniofacial Journal, the International Journal of Language and Communication(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)
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)
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)
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)
OBJECTIVE To investigate consonant production at 12 and 18 months of age following early soft palate repair in infants with unilateral cleft lip and palate (UCLP), and to compare it with typically developing children without clefts. DESIGN Randomized study with comparison group. PARTICIPANTS Twenty Swedish infants born with UCLP and 21 without clefts(More)
