During dialysis treatments, there is an interest of measuring the dialysis efficiency for each treatment. An easy method has been developed and is based on measuring the conductivity of the dialysis fluid. Today this method exists in the dialysis machines for standard hemodialysis (HD) treatments, and for the so called postdilution hemodiafiltration (HDF) treatments at Gambro Lundia AB. However...

Recent work has shown the important properties of the wind inversion residual or Maximum Likelihood Estimator (MLE) for Quality Control (QC) of QuikSCAT Hierarchichal Data Format (HDF) observations. Since March 2000, the QuikSCAT Near-Real Time (NRT) Binary Universal Format Representation (BUFR) product is available. As this product is used for Numerical Weather Prediction (NWP) assimilation pu...

Earth Observing System (EOS) is one of NASA's large programs for Earth science and global change research. In order to process, distribute, and archive data from EOS satellites and to facilitate interdisciplinary research, NASA has developed the EOS Data and Information System (EOSDIS) that defines a set of standards to deal with remote sensing data. In EOSDIS, data are grouped into three conce...

UNLABELLED Resistance to erythropoiesis stimulating agents (ESA) is common in patients undergoing chronic hemodialysis (HD) treatment. ESA responsiveness might be improved by enhanced clearance of uremic toxins of middle molecular weight, as can be obtained by hemodiafiltration (HDF). In this analysis of the randomized controlled CONvective TRAnsport STudy (CONTRAST; NCT00205556), the effect of...

The discovery of HDF J123652+621227, a candidate gravitational lens in the HDF, is reported. This lens may be multiply imaging several optical sources at different redshifts. If follow-up spectroscopy of the lens and the brightest image confirms this hypothesis, observations of this system alone can be used to obtain an estimate of the redshift distribution at extremely faint flux levels. Subje...

BACKGROUND Skin pigmentation is a common problem for dialysis patients, but little is known about the factor responsible for the colour intensity. Middle-molecular-weight (MMW) substances have been suggested to be responsible for the skin colour. Several papers have reported that β(2)-microglobulin (β(2)-MG) correlates with the skin colour, and haemodiafiltration (HDF) is effective to reduce th...

During an outbreak of methanol poisonings in the Czech Republic in 2012, we were able to study methanol and formate elimination half-lives during intermittent hemodialysis (IHD) and continuous veno-venous hemodialysis/hemodiafiltration (CVVHD/HDF) and the relative impact of dialysate and blood flow rates on elimination. Data were obtained from 11 IHD and 13 CVVHD/HDF patients. Serum methanol an...

We present a model-independent method of quantifying galaxy evolution in high-resolution images, which we apply to the Hubble Deep Field (HDF). Our procedure is to k-correct the pixels belonging to the images of a complete set of bright galaxies and then to replicate each galaxy image to higher redshift by the product of its space density, 1/Vmax, and the cosmological volume. The set of bright ...

BACKGROUND Despite the growing interest in haemodiafiltration (HDF), there is no information on the costs and cost-utility of this dialysis modality yet. It was therefore our objective to study the cost-utility of HDF versus haemodialysis (HD). METHODS A cost-utility analysis was performed using a Markov model. It included data from the Convective Transport Study (CONTRAST), a randomized cont...
