Correction to: Lossy Image Compression in a Preclinical Multimodal Imaging Study

Lossy Image Compression in a Preclinical Multimodal Imaging Study

The growing use of multimodal high-resolution volumetric data in pre-clinical studies leads to challenges related to the management and handling of the large amount of these datasets. Contrarily to the clinical context, currently there are no standard guidelines to regulate the use of image compression in pre-clinical contexts as a potential alleviation of this problem. In this work, the authors study the appli...

Common variants in Alzheimer's disease and risk stratification by polygenic ris...

Genetic discoveries of Alzheimer's disease are the drivers of our understanding, and together with polygenetic risk stratification can contribute towards planning of feasible and efficient preventive and curative clinical trials. We first perform a large genetic association study by merging all available case-control datasets and by-proxy study results (discovery n = 409,435 and validation size n = 58,190). Her...

Microbiome definition re-visited: old concepts and new challenges

The field of microbiome research has evolved rapidly over the past few decades and has become a topic of great scientific and public interest. As a result of this rapid growth in interest covering different fields, we are lacking a clear commonly agreed definition of the term ``microbiome.'' Moreover, a consensus on best practices in microbiome research is missing. Recently, a panel of international experts dis...

Evaluating heterotrophic growth in a nitrifying biofilm reactor using fluoresce...

The objective of this study was to evaluate the significance of heterotrophic growth in nitrifying biofilm reactors fed only with ammonium as an energy source. The diversity, abundance and spatial distribution of nitrifying bacteria were studied using a combination of molecular tools and mathematical modeling, in two biofilm reactors operated with different hydraulic retention times. The composition and distrib...

Study of nitrifying bacteria diversity on biofilms using a molecular approach

The purpose of this work was to investigate the microbial community structure of nitrifying biofilms. Biofilm samples were collected from two reactors operated with distinct retention times. The composition and spatial distribution of nitrifying consortia in biofilms was quantified by fluorescence in situ hybridization (FISH) with rRNA-targeted oligonucleotide probes combined with confocal laser scanning micros...

Nitrifying and heterotrophic population dynamics in biofilm reactors: effects o...

Two biofilmreactors operated with hydraulic retention times of 0.8 and 5.0 h were used to study the links between population dynamics and reactor operation performance during a shift in process operation from pure nitrification to combined nitrification and organic carbon removal. The ammonium and the organic carbon loads were identical for both reactors. The composition and dynamics of the microbial consortia ...

Microbial community composition and function in wastewater treatment plants

Biological wastewater treatment has been applied for more than a century to ameliorate anthropogenic damage to the environment. But only during the last decade the use of molecular tools allowed to accurately determine the composition, and dynamics of activated sludge and biofilm microbial communities. Novel, in many cases yet not cultured bacteria were identified to be responsible for filamentous bulking and f...
