07/2016 - Methodological issues on the use of administrative data in healthcare research: the case of heart failure hospitalizations in Lombardy region, 2000 to 2012
Background Administrative data are increasingly used in healthcare research. However, in order to avoid biases, their use requires careful study planning. This paper describes the methodological principles and criteria used in a study on epidemiology, outcomes and process of care of patients hospitalized for heart failure (HF) in the largest Italian Region, from 2000 to […]
05/2016 - Microtubule doublets are double-track railways for intraflagellar transport trains
The cilium is a large macromolecular machine that is vital for motility, signaling, and sensing in most eukaryotic cells. Its conserved core structure, the axoneme, contains nine microtubule doublets, each comprising a full A-microtubule and an incomplete B-microtubule. However, thus far, the function of this doublet geometry has not been understood. We developed a time-resolved […]
04/2016 - Autoantibody pathogenicity in a multifocal motor neuropathy induced pluripotent stem cell–derived model
Objective We investigated the pathogenicity of immunoglobulin M (IgM) anti‐GM1 antibodies in serum from patients with multifocal motor neuropathy (MMN) using human induced pluripotent stem cell (iPSC)‐derived motor neurons (MNs). Methods iPSCs were generated from fibroblasts and differentiated into MNs. We studied the binding of IgM to MNs, their complement‐activating properties, and effects on structural […]
01/2016 - Identification of neutral tumor evolution across cancer types
Despite extraordinary efforts to profile cancer genomes, interpreting the vast amount of genomic data in the light of cancer evolution remains challenging. Here we demonstrate that neutral tumor evolution results in a power-law distribution of the mutant allele frequencies reported by next-generation sequencing of tumor bulk samples. We find that the neutral power law fits […]
