High density lipoprotein (HDL) can be quantitated by measurement of cholesterol in supernates after precipitation of low and very low density lipoprotein (LDL and VLDL) with heparin and Mn(2+). Supernatant turbidity, often observed with hypertriglyceridemic specimens, indicates incomplete sedimentation of LDL/VLDL and precludes accurate quantitation of HDL. Ten Lipid Research Clinic Laboratorie...

A significant proportion of patients treated for acute decompensated heart failure (ADHF) suffer from worsening renal function, which is often associated with medical therapy resistance and poor outcome. In this setting, haemofiltration has been used for more than 30 years, despite inconclusive evidence for its advantages. In the last decade, a major technological advances have made available a...

BACKGROUND Ovarian hyperstimulation syndrome (OHSS) is a recognized complication of ovulation induction, occurring in 1-10% of IVF and embryo transfer cycles. While mild OHSS is of no clinical relevance, severe OHSS is a life threatening complication. However, the efficacy of prevalent treatments appeared to be limited. We developed a continuous autotransfusion system with an ultrafiltration in...

Sodium dodecyl sulfate (SDS) is commonly used to extract membrane proteins in proteomics studies; however, it can reduce the efficiency of tryptic digestion and interfere with the results of liquid chromatography-mass spectrometry (LC-MS) analysis. Available methods for removing surfactants, such as ultrafiltration, acetone precipitation, and gel electrophoresis, are not completely satisfactory...

More than 1 million heart failure hospitalizations occur annually, and congestion is the predominant cause. Rehospitalizations for recurrent congestion portend poor outcomes independently of age and renal function. Persistent congestion trumps serum creatinine increases in predicting adverse heart failure outcomes. No decongestive pharmacological therapy has reduced these harmful consequences. ...

an innovative method based on the membrane bioreactor (mbr) technology was developed as a potential remedy for the water shortage. mbrs attracted much attention in the field of wastewater treatment and reuse. it is reported from many researchers that membrane bioreactor technology is feasible and an efficient method for the treatment of wastewater. however, mbrs are faced to membrane fouling whic...

OBJECTIVES We sought to investigate the possibility that lung diffusing capacity reduction observed in chronic heart failure is reversible in the short term. BACKGROUND Mechanical properties of the lung usually ameliorate with antifailure treatment including drugs, ultrafiltration and heart transplantation, whereas lung diffusion rarely improves. METHODS We studied the mechanical properties...

Iron (Fe) isotopes are now recognized as useful tracers of Fe sources and biogeochemical processes in natural environments but many uncertainties remain regarding the mechanisms that control their isotopic fractionation. Ultrafiltration techniques applied to separate species could potentially bias compositions. Here, we investigated frontal centrifugal ultrafiltration. We have set up time-ultra...

The large-scale AVOID-HF (Aquapheresis Versus Intravenous Diuretics and Hospitalization for Heart Failure) trial compared ultrafiltration and medical treatment in acute heart failure (HF) (1). A major advantage of this study was the use of adjustable, rather than fixed, treatment regimens in both arms. The study was terminated early but still could demonstrate a nonsignificant trend for longer ...
