Objective: To perform a systematic review and meta-analysis to determine whether fluid and imaging astrocyte biomarkers are altered in Alzheimer's disease (AD). Methods: PubMed and Web of Science databases were searched for articles reporting fluid or imaging astrocyte biomarkers in AD. Pooled effect sizes were determined with mean differences (SMD) using the Hedge’s G method with random-effects to determine biomarker performance. Adapted questions from QUADAS-2 were applied for quality assessment. A protocol for this study...

Data from: Isolation and characterization of microsatellite loci for the isopod crustacean Armadillidium vulgare and transferability in terrestrial isopods

Isabelle Giraud, Victorien Valette, Nicolas Bech, Frédéric Grandjean & Richard Cordaux
Armadillidium vulgare is a terrestrial isopod (Crustacea, Oniscidea) which harbors Wolbachia bacterial endosymbionts. A. vulgare is the major model for the study of Wolbachia-mediated feminization of genetic males in crustaceans. As a consequence of their impact on host sex determination mechanisms, Wolbachia endosymbionts are thought to significantly influence A. vulgare evolution on various grounds, including population genetic structure, diversity and reproduction strategies. To provide molecular tools for examining these questions, we isolated microsatellite loci through...

Data from: In situ filamentous communities from the Ediacaran (~563 Ma) of Brazil

Precambrian filamentous microfossils are common and diverse. Nevertheless, their taxonomic assignment can be difficult due to their overall simple shapes typically lacking in diagnostic features. Here, we report in situ communities of well-preserved, large filamentous impressions from the Ediacaran Itajaí Basin (ca. 563 Ma) of Brazil. The filaments are uniserial (unbranched) and can reach up to 200 µm in width and up to 44 mm in length. They occur as both densely packed or sparsely...

Data from: Host tissues as microhabitats for Wolbachia and quantitative insights into the bacterial community in terrestrial isopods

Jessica Dittmer, Sophie Beltran-Bech, Jérôme Lesobre, Maryline Raimond, Monique Johnson & Didier Bouchon
Animal–bacterial symbioses are highly dynamic in terms of multipartite interactions, both between the host and its symbionts as well as between the different bacteria constituting the symbiotic community. These interactions will be reflected by the titres of the individual bacterial taxa, for example via host regulation of bacterial loads or competition for resources between symbionts. Moreover, different host tissues represent heterogeneous microhabitats for bacteria, meaning that host-associated bacteria might establish tissue-specific bacterial communities. Wolbachia are...

Wide spectrum and high frequency of genomic structural variation, including transposable elements, in large double stranded DNA viruses

Clement Gilbert, Elisabeth Herniou, Yannis Moreau, Nicolas Lévêque, Carine Meignin, Laurent Daeffler, Brian Federici, Richard Cordaux & Vincent Loiseau
Our knowledge of the diversity and frequency of genomic structural variation segregating in populations of large double stranded (ds) DNA viruses is limited. Here we sequenced the genome of a baculovirus (AcMNPV) purified from beet armyworm (Spodoptera exigua) larvae at depths >195,000X using both short-read (Illumina) and long-read (PacBio) technologies. Using a pipeline relying on hierarchical clustering of structural variants (SVs) detected in individual short- and long-reads by six variant callers, we identified a total...
