    Der Arbeitsalltag von Wissenschaftlerinnen und Wissenschaftlern hat sich in den letzten Jahren dramatisch verĂ€ndert. Forschen, Schreiben und Publizieren sind mittlerweile stark durch netzbasierte Anwendungen geprĂ€gt. Das digitale Zeitalter aber hat nicht nur neue technische Werkzeuge hervorgebracht, sondern auch neue Wege eröffnet, um Wissen zu generieren und zu verbreiten. Dies gilt sowohl innerhalb der akademischen Welt als auch ĂŒber diese hinaus. Das Arbeiten mit dem Netz stellt unsere bisherigen etablierten wissenschaftlichen Praktiken in Frage. Forschung wird zunehmend vernetzt, kollaborativ, multimedial, trans- bzw. interdisziplinĂ€r durchgefĂŒhrt. Das vorliegende Handbuch beschreibt diese sich herausbildenden wissenschaftlichen Praktiken. Ziel der Autoren war es dabei, ein praxisnahes und leicht verstĂ€ndliches Handbuch zu schreiben

    This is the author accepted manuscript. The final version is available from the publisher via the DOI in this recordAPOE Δ4, the most significant genetic risk factor for Alzheimer disease (AD), may mask effects of other loci. We re-analyzed genome-wide association study (GWAS) data from the International Genomics of Alzheimer's Project (IGAP) Consortium in APOE Δ4+ (10 352 cases and 9207 controls) and APOE Δ4- (7184 cases and 26 968 controls) subgroups as well as in the total sample testing for interaction between a single-nucleotide polymorphism (SNP) and APOE Δ4 status. Suggestive associations (P<1 × 10-4) in stage 1 were evaluated in an independent sample (stage 2) containing 4203 subjects (APOE Δ4+: 1250 cases and 536 controls; APOE Δ4-: 718 cases and 1699 controls). Among APOE Δ4- subjects, novel genome-wide significant (GWS) association was observed with 17 SNPs (all between KANSL1 and LRRC37A on chromosome 17 near MAPT) in a meta-analysis of the stage 1 and stage 2 data sets (best SNP, rs2732703, P=5·8 × 10-9). Conditional analysis revealed that rs2732703 accounted for association signals in the entire 100-kilobase region that includes MAPT. Except for previously identified AD loci showing stronger association in APOE Δ4+ subjects (CR1 and CLU) or APOE Δ4- subjects (MS4A6A/MS4A4A/MS4A6E), no other SNPs were significantly associated with AD in a specific APOE genotype subgroup. In addition, the finding in the stage 1 sample that AD risk is significantly influenced by the interaction of APOE with rs1595014 in TMEM106B (P=1·6 × 10-7) is noteworthy, because TMEM106B variants have previously been associated with risk of frontotemporal dementia. Expression quantitative trait locus analysis revealed that rs113986870, one of the GWS SNPs near rs2732703, is significantly associated with four KANSL1 probes that target transcription of the first translated exon and an untranslated exon in hippocampus (P≀1.3 × 10-8), frontal cortex (P≀1.3 × 10-9) and temporal cortex (P≀1.2 × 10-11). Rs113986870 is also strongly associated with a MAPT probe that targets transcription of alternatively spliced exon 3 in frontal cortex (P=9.2 × 10-6) and temporal cortex (P=2.6 × 10-6). Our APOE-stratified GWAS is the first to show GWS association for AD with SNPs in the chromosome 17q21.31 region. Replication of this finding in independent samples is needed to verify that SNPs in this region have significantly stronger effects on AD risk in persons lacking APOE Δ4 compared with persons carrying this allele, and if this is found to hold, further examination of this region and studies aimed at deciphering the mechanism(s) are warranted

    Multiancestry analysis of the HLA locus in Alzheimer’s and Parkinson’s diseases uncovers a shared adaptive immune response mediated by HLA-DRB1*04 subtypes

    Across multiancestry groups, we analyzed Human Leukocyte Antigen (HLA) associations in over 176,000 individuals with Parkinson’s disease (PD) and Alzheimer’s disease (AD) versus controls. We demonstrate that the two diseases share the same protective association at the HLA locus. HLA-specific fine-mapping showed that hierarchical protective effects of HLA-DRB1*04 subtypes best accounted for the association, strongest with HLA-DRB1*04:04 and HLA-DRB1*04:07, and intermediary with HLA-DRB1*04:01 and HLA-DRB1*04:03. The same signal was associated with decreased neurofibrillary tangles in postmortem brains and was associated with reduced tau levels in cerebrospinal fluid and to a lower extent with increased AÎČ42. Protective HLA-DRB1*04 subtypes strongly bound the aggregation-prone tau PHF6 sequence, however only when acetylated at a lysine (K311), a common posttranslational modification central to tau aggregation. An HLA-DRB1*04-mediated adaptive immune response decreases PD and AD risks, potentially by acting against tau, offering the possibility of therapeutic avenues

    Current and Future Status of Concentrated Solar Power in the EU

    No full text
    Concentrating Solar Power is under development in Europe since the 1970s. Presently the work is focused on raising efficiencies and reducing cost. Therefore a wide variety of actions are carried out to strengthen synergies between European researchers, and to give industry the opportunity to implement competitive technologies into the market. The paper gives an overview on recent work on line and point focusing systems, new storage technologies, and the integration into other processes than power production, like fuel production water production or process heat generation
