question:
The direct detection of haplotypes from short-read DNA sequencing data requires changes to existing small-variant detection methods. Here, we develop a Bayesian statistical framework which is capable of modeling multiallelic loci in sets of individuals with non-uniform copy number. We then describe our implementation of this framework in a haplotype-based variant detector, FreeBayes.
answer:
Haplotype-based variant detection from short-read sequencing

question:
Systematic literature reviews are widely used as an aid to evidence based decision making. For example, reviews of randomised controlled trials are regularly used to answer questions about the effectiveness of healthcare interventions. The high profile of systematic reviews as a cornerstone of evidence based medicine, however, has led to several misconceptions about their purpose and methods. Among these is the belief that systematic reviews are applicable only to randomised controlled trials and that they are incapable of dealing with other forms of evidence, such as from non-randomised studies or qualitative research. The systematic literature review is a method of locating, appraising, and synthesising evidence. The value of regularly updated systematic reviews in the assessment of effectiveness of healthcare interventions was dramatically illustrated by Antman and colleagues, who showed that review articles failed to mention advances in treatment identified by an updated systematic review.1 It is nearly a quarter of a century since Gene Glass coined the term "meta-analysis" to refer to the quantitative synthesis of the results of primary studies.2 The importance of making explicit efforts to limit bias in the review of literature, however, has been emphasised by social scientists at least since the 1960s.3 In recent years systematic reviews have found an important role in health services research, and the growing interest in evidence based approaches to decision making makes it likely that their use will increase. Not everybody accepts that systematic reviews are necessary or desirable, and as one moves further away from the clinical applications of systematic reviews cynicism about their utility grows. Several arguments are commonly used to reject a wider role for systematic reviews, and these arguments are often based on major misconceptions about the history, purpose, methods, and uses of systematic reviews. I have examined eight common myths about

question:
Gram-negative bacteria use the Type VI secretion system (T6SS) to inject toxic proteins into rival bacteria or eukaryotic cells. However, the mechanism of the T6SS is incompletely understood. In the present study, we investigated a conserved component of the T6SS, TssK, using the antibacterial T6SS of Serratia marcescens as a model system. TssK was confirmed to be essential for effector secretion by the T6SS. The native protein, although not an integral membrane protein, appeared to localize to the inner membrane, consistent with its presence within a membrane-anchored assembly. Recombinant TssK purified from S. marcescens was found to exist in several stable oligomeric forms, namely trimer, hexamer and higher-order species. Native-level purification of TssK identified TssF and TssG as interacting proteins. TssF and TssG, conserved T6SS components of unknown function, were required for T6SS activity, but not for correct localization of TssK. A complex containing TssK, TssF and TssG was subsequently purified in vitro, confirming that these three proteins form a new subcomplex within the T6SS. Our findings provide new insight into the T6SS assembly, allowing us to propose a model whereby TssK recruits TssFG into the membrane-associated T6SS complex and different oligomeric states of TssK may contribute to the dynamic mechanism of the system.
answer:
Biochemical analysis of TssK, a core component of the bacterial Type VI secretion system, reveals distinct oligomeric states of TssK and identifies a TssKTssFG subcomplex
