High-flux hemodialysis (which removes large toxins) reduces the risk of premature death in many patients with chronic kidney disease (CKD), according to a study appearing in the March 2009 issue of the Journal of the American Society Nephrology (JASN). The results suggest that this procedure could be beneficial for those with poor prognoses and those with diabetes.
In patients with CKD, toxins accumulate in the blood because the kidneys lose their ability to eliminate these substances sufficiently. CKD patients undergo either high-flux or low-flux hemodialysis to clear these toxins from the body (high-flux membranes have larger pores that allow for the removal of toxins of greater molecular size). While epidemiological studies have indicated that treatment with high-flux hemodialysis improved survival, the true potential of this treatment on prolonging life has not been clearly determined.
Francesco Locatelli, MD (A. Manzoni Hospital, Lecco, Italy), and his colleagues in eight European countries conducted a clinical trial to investigate the effect of high-flux hemodialysis on patient survival. In a randomized clinical trial called the Membrane Permeability Outcome (MPO) study, they enrolled 738 hemodialysis patients and assigned them to either low-flux or high-flux hemodialysis. Patients were followed for 3 to 7.5 years; in the entire study group the researchers did not detect a significant survival benefit with either high-flux or low-flux hemodialysis, but the use of high-flux membranes conferred a significant survival benefit in higher-risk patients. In addition, patients with diabetes showed a survival benefit with high-flux dialysis.
These findings could lead to potentially valuable clinical benefits for patients with CKD. However, because the benefits in diabetic patients were found only after a post-hoc analysis of the data, Dr. Locatelli's team noted that their results in diabetic patients need to be confirmed by other clinical trials.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
