not effi cacious if not associated with dietary restriction and P binders. In this issue of Blood Purifi cation , Bolasco et al. compared P kinetics in standard HD and on-line hemodiafi ltration with endogenous reinfusion (HFR) by using a new method to measure P levels into the dialysate. This issue is of interest because sensitivity of the common automatic analyzers is inadequate to precisely ...

We studied the temporal patterns of tracer throughput in the out ̄ow of large (30 cm diameter by 38 cm long) undisturbed cores from the Panola Mountain Research Watershed, Georgia. Tracer breakthrough was a€ected by soil structure and rainfall intensity. Two rainfall intensities (20 and 40 mm hr71) for separate Cl7 and Br7 amended solutions were applied to two cores (one extracted from a hillslo...

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 ...

Introduction: Hospital acquired infections (HAI) are the number four cause of death in the United States at an annual cost estimated at $40 billion. With emerging scienti c data regarding the contribution of air contamination to surgical site infections (SSI), there is increased interest in considering innovative adjunctive technologies to support best air quality in operating rooms (ORs). Obje...

Background: Bone marrow aspiration and/or biopsy (BMAB) is a procedure used to diagnose and follow up various haematological diseases. It is usually performed at either the sternum or the iliac crest. Th e procedure oft en causes pain despite local infi ltration anaesthesia. Th e objective of this study was to evaluate diff erent means of pain relief during BMAB in adult patients. Special atten...

cifi c. The high plasma creatinine level in the newborn sometimes refl ects the mother’s plasma creatinine level (9). However, kidney function of the mother of the newborn was within normal limits at the time of Caesarean section; plasma creatinine level of 0.7 mg/dL. An elevated plasma creatinine level is observed frequently in premature infants due to immaturity of the kidney tissue and will ...

Pompe disease (PD) or glycogen storage disease type II, is an autosomal recessive disorder characterized by a defi ciency in the lysosomal enzyme acid alpha-glucosidase. Several phenotypes have been described, ranging from rapidly progressive infantile forms to slowly progressive late-onset forms. Recent studies have shown that magnetic resonance imaging (MRI), based principally on signal inten...

The space of Hermitian matrices is stratiied according to the multiplicities of the eigenvalues. This stratiication is responsible for the quantum Hall eeect. We study the simplest properties of this stratiication: give explicit expressions for the Poincar e duality and the Alexander mapping, and prove that the spectral sequence generated by the ltration by matrices having at most i diierent ei...

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 ...

INTRODUCTION For two decades, various countries have experienced an epidemic of chronic kidney disease unexplainable by traditional causes. Typically a chronic tubulointerstitial nephritis, it predominantly affects young male agricultural workers and has been reported in several countries in Central America, as well as in Sri Lanka, India and Egypt. Recent studies in El Salvador have also repor...
