Abstract Background Ultrasound (US) has largely replaced contrast venography as the definitive diagnostic test for deep vein thrombosis (DVT). We aimed to derive a estimate of accuracy US clinically suspected DVT and identify study-level factors that might predict accuracy. Methods undertook systematic review, meta-analysis meta-regression cohort studies compared in patients with DVT. searched Medline, EMBASE, CINAHL, Web Science, Cochrane Database Systematic Reviews, Controlled Trials...
Decomposition of organic material by soil microbes generates an annual global release 50-75 Pg carbon to the atmosphere, ∼7.5-9 times that anthropogenic emissions worldwide. This process is sensitive change factors, which can drive cycle-climate feedbacks with potential enhance atmospheric warming. Although effects interacting factors on microbial activity have been a widespread ecological focus, regulatory interspecific interactions are rarely considered in climate feedback studies. We...
The relative contribution of top‐down and bottom‐up processes regulating primary decomposers can influence the strength link between soil animal community ecosystem functioning. Although bacterial communities are regulated by processes, latter considered to be less important in structuring diversity functioning fungal‐dominated ecosystems. Despite huge mycophagous (fungal‐feeding) fauna, their potential reverse outcomes competitive fungal interactions, grazing effects have never been found...
Nitrous oxide (N2O) is a greenhouse gas and the main anthropogenic emission contributing to stratospheric ozone depletion. Agricultural soils dominate N2O emissions but there very limited information specifically relating relative soil diffusivity (Dp/Do) emissions. This study was conducted determine effects of bulk density (ρb) matric potential (ψ) on Dp/Do associated fluxes in presence denitrification substrates. The interaction between ρb ψ investigated using 880 repacked cores that were...
Core Ideas Relative gas diffusivity controls both N 2 O and emissions. integrates the effects of soil bulk density matric potential. Nitrogen use efficiency is likely to be driven by physics. Knowledge biological physical interactions with respect fluxes essential ensure that agricultural land management environmentally economically sustainable. This study determined how varying relative ( D p / o ) affected cumulative under simulated ruminant urinary‐N deposition. Using repacked cores, (ρ b...
River systems are dynamic, highly connected water transfer networks that integrate a wide range of physical and biological processes. We used river network nitrogen (N) removal model with daily temporal resolution to evaluate how elevated N inputs, saturation the denitrification total nitrate processes, hydrologic conditions interact determine amount, timing distribution in fifth‐order suburban 400 km 2 basin. Denitrification parameters were based on results from whole reach 15 NO 3 tracer...
There are limited data on the prognostic value of cardiovascular magnetic resonance measurements in idiopathic pulmonary arterial hypertension, with no studies investigating impact correction indices for age and sex value.Consecutive patients hypertension underwent imaging at 1.5T. Steady-state free precession cardiac volumes mass were corrected age, sex, body surface area according to reference significance assessed. A total 80 identified, 23 died during mean follow-up 32±14 months....
Abstract Terrestrial ecosystems, both natural ecosystems and agroecosystems, generate greenhouse gases (GHGs). The chamber method is the most common to quantify GHG fluxes from soil–plant systems better understand factors affecting their generation mitigation. objective of this study was review synthesize literature on designs (non‐flow‐through, non‐steady‐state chamber) associated that affect nitrous oxide (N 2 O) flux measurement when using methods. Chamber design requires consideration...
Abstract Sequestration of soil organic carbon (SOC) has been recognized as an opportunity to off‐set global dioxide (CO 2 ) emissions. Flipping (full inversion 1–3 m) is a practice used on New Zealand's South Island West Coast eliminate water‐logging in highly podzolized sandy soils. results burial SOC formed surface horizons into the subsoil and transfer material low “new” topsoil. The aims this study were quantify changes storage stability over 20‐year period following flipping...
Understanding the physical and hydraulic properties of vadose zone is important for modeling land use effects on groundwater quality. This study used a variety characterization methods to derive conceptual understanding estimates coarse alluvial gravel in New Zealand. Sandy (SG) material constituted approximately 90% zone, with remainder comprising sand lenses open‐framework gravels. The content SG was 70% (v/v) (range 68–73%). water bulk (43 samples) ranged from 3.5 13.9%. average density...
Information is reviewed on root infection of potato by the plasmodiophorid Spongospora subterranea f. sp. . This pathogen has long been recognized as cause galls (hyperplasia) and economically important disease powdery scab tubers (modified stolons). The significance for plant productivity zoosporangium stages in roots only recently begun to be documented. Two experiments are described that assessed effects S. function productivity. A greenhouse experiment measured parameters eight cultivars...
The rapid introduction of endovascular abdominal aortic aneurysm repair (EVAR) has considerable implications for the management (AAA). This study was undertaken to determine an optimal strategy use EVAR based on best currently available evidence.Economic modelling and probabilistic sensitivity analysis considered reference cases representing a fit 70-year-old with 5.5-cm diameter AAA (RC1) 80-year-old 6.5-cm unfit open surgery (RC2). Results were assessed as incremental cost-effectiveness...
