We discuss the identification of sources detected by the Infrared Space Observatory (ISO) at 6.7 and 15 11m in the Hubble Deep Field (HDF) region. We conservatively associate ISO sources with objects in existing optical and near-infrared HDF catalogues using the likelihood ratio method, confirming these results (and, in one case, clarifying them) with independent visual searches. We find 15 ISO...

Large membrane pores and large quantities of reinfusion fluids can influence the dialytic balance of trace elements in haemodiafiltration (HDF). As there are no studies in HDF with on-line produced reinfusate, we studied plasma or whole blood (*) concentrations of trace elements (Al, Cd*, Cr* and Se: microg/l; Cu, Pb* and Zn*: microg/dl) of 24 on-line HDF, 20 haemodialysis (HD) patients and 66 ...

Abstract Evidence concerning online hemodiafiltration (ol-HDF) includes increased uremic toxin removal, prevention of dialysis-related hypotension, improved survival, and recovery uncertain symptoms. In particular, evidence has been shown regarding dialysis hypotension improvement but the mechanism its manifestation is still unclear effects themselves are questionable. Japan, pre dilution ol-HD...

BACKGROUND AND OBJECTIVE Increased left ventricular mass (LVM), low ventricular ejection fraction (EF), and high pulse-wave velocity (PWV) relate to overall and cardiovascular mortality in patients with ESRD. The aim of this study was to determine the effect of online hemodiafiltration (HDF) versus low-flux hemodialysis (HD) on LVM, EF, and PWV. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS E...

BACKGROUND Standard low-flux haemodialysis (HD) is not very efficacious, and patient morbidity and mortality rates are still very high. According to the initial study design, the MPO study reported that high-flux HD (hf-HD) showed a significant 37% relative risk reduction of mortality in patients with serum albumin ≤4 g/dl; online haemodiafiltration (HDF) is considered the most efficient techni...

BACKGROUND/AIMS Plasma concentrations of the N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) are increased in end-stage renal disease. Improvement in hemodynamic stability has been reported when switching from hemodialysis (HD) to on-line hemodiafiltration (ol-HDF). The aim of this study was to investigate plasma concentrations of NT-proBNP, BNP and neuropeptide Y (NPY) during ...

NeXus is a joint effort of both the synchrotron and neutron scattering community to develop a common data exchange format based on HDF. In order to simplify access to NeXus files a NeXus-API is provided. This NeXus-API has been restructured and expanded to cover both HDF versions 4 and 5. Only small changes to the API were necessary in order to accomplish this. A foundation was laid to extend t...

Although it is just over a year since the data was made public, the HDF exposure has stimulated considerable progress towards our understanding of the faint galaxy population. I present a brief personal account of the history of faint galaxy studies culminating in the HDF, and describe what I consider to be the main highlights thus far from this remarkable image. The HDF has given considerable ...

Ficheux et al. may result from the method of TMP calculation. If only three pressure points are known, the fourth one (inlet dialysate pressure) must be inferred or assumed, so introducing great variability related to dialyser characteristics and operational setting. The impact of the fourth point on TMP calculation is highly significant and the error is increased by disregarding the contributi...
