Divergent composition but similar function of soil food webs of individual plants: plant species and community effects
T. M. Bezemer,Michelle T. Fountain,J. M. Barea,Soren Christensen,Stefan C. Dekker,Henk Duyts,R. van Hal,Jeffrey A. Harvey,Katarina Hedlund,Mark Maraun,Juha Mikola,A. G. Mladenov,Christophe Robin,P.C. de Ruiter,P.C. de Ruiter,Stefan Scheu,Heikki Setälä,Petr Šmilauer,W.H. van der Putten +18 more
TL;DR: Soils are extremely rich in biodiversity, and soil organisms play pivotal roles in supporting terrestrial life, but the role that individual plants and plant communities play in influencing the diversity and functioning of soil food webs remains highly debated.
The effect of long‐term mercury pollution on the soil microbial community
TL;DR: The effect of long-term exposure to mercury on the soil microbial community was investigated in soil from three different sites along a pollution gradient, and the bacterial and protozoan populations was reduced in the most contaminated soil, whereas there was no significant difference in fungal biomass measured as chitinase activity.

Comparison of Computed Tomography Perfusion and Magnetic Resonance Imaging Perfusion-Diffusion Mismatch in Ischemic Stroke
Bruce C.V. Campbell,Soren Christensen,Christopher R Levi,Patricia Desmond,Geoffrey A. Donnan,Stephen M. Davis,Mark W Parsons +6 more
TL;DR: Quantitative CTP mismatch classification using relCBF and Tmax is similar to perfusion-diffusion MRI, and the greater accessibility of CTP may facilitate generalizability of mismatch-based selection in clinical practice and trials.

Review of Perfusion Imaging in Acute Ischemic Stroke: From Time to Tissue.
TL;DR: An overview of computed tomography perfusion (CTP) and perfusion magnetic resonance imaging (MRP) in acute ischemic stroke and discuss technical properties, clinical use, and pitfalls is given in this article.

Automatic selection of arterial input function using cluster analysis
TL;DR: A completely automatic procedure for establishing the arterial input function (AIF) representing the delivery of intravascular tracer to tissue is suggested based on a cluster analysis algorithm that provides means for objectively assessing AIF candidates in local AIF search algorithms designed to reduce bias due to delay and dispersion.
