(ADQI) VIII consensus statements on the treatment of patients with hepatorenal syndrome (HRS) and acute kidney injury [1]. While we appreciate the authors’ discussion, we question the hemodynamic recommen dations and suggest further areas of study (Section III in [1]). Renal perfusion relies upon cardiac output, renal blood fl ow, and autoregulation. HRS infl uences cardiac output and systemic ...

Distribution, mobility and toxicity of metals in natural waters are strongly related to their aqueous speciation. To understand the behaviour of an aqueous element and the transformation between chemical species, there is a need for reliable methods that enable measurements of specifi c fractions of metals. Ultrafi ltration has frequently been used to study speciation of metals in natural water...

K. Janiszewski, B. Panic: Silesian University of Technology, Department of Metallurgy, Katowice, Poland Hitherto existing investigations concerning the ceramic fi lter use in the steel making processes have given good results. The obtained results of fi ltration have proved that this method may be used as an eff ective and cheap way of steel fi ltration from non-metallic inclusions. Placing fi ...

K. Janiszewski, Silesian University of Technology, Department of Metallurgy, Katowice, Poland. Hitherto existing investigations concerning the ceramic fi lter use in the steel making processes (both of laboratory and industrial scale) have given good results. The obtained results of fi ltration (in the laboratory) have proved that this method may be used as an eff ective and cheap way of steel ...

We appreciate the comments by Dr O’Connell and colleagues on our article published in CHEST 1 describing the cumulative incidence and pretransplant risk factors for post-lung transplant renal dysfunction in adult patients with cystic fi brosis (CF). We agree that serum creatinine concentration alone should not be relied upon solely to assess renal function in CF because of its poor sensitivity....

2108 Th e eff ect of cell preparation methods on the surface chemistry and retention of Escherichia coli D21 g was investigated over a range of ionic strength conditions. Th e cell preparation methods that were considered included fi ltration and centrifugation (at various speeds and for diff erent durations). For a given ionic strength condition, it was found that cells prepared by fi ltration...
