Activity and stability of horse‐liver alcohol dehydrogenase in sodium dioctylsulfosuccinate/cyclohexane reverse micelles

Horse liver alcohol dehydrogenase (EC 1.1.1.1) solubilized in sodium dioctylsulfosuccinate (AOT)/cyclohexane reverse micelles was used for the oxidation of ethanol and reduction of cyclohexanone in a coupled substrate/coenzyme recycling system. The activity of the enzyme was studied as a function of pH and water content. The enzyme was optimally active in microemulsions prepared with buffer of pH

Illusions (e74), for ehn, cl, bsn, tpt, tbn, vla, vlc

This score is a 100% recomposition of my earlier piece illusions (#74/2006). As before, this music references and is inspired by a report titled, “Demonstrations of Auditory Illusions and Tricks” by Yoshitaka Nakajima, Takayuki Sasaki & Gert ten Hoopen.This piece is based on five classes of auditory illusions that were reported by Yoshitaka Nakajima, Takayuki Sasaki, & Gert ten Hoopen.

Evaluating the safety benefit of retrofitting motorways section with barriers meeting a new EU standard : Comparison of observational before–after methodologies

The road safety barriers are today designed and installed in compliance with the European standards for Road Restraint Systems (EN 1317), which lays down common requirements for the testing and certification in all EU countries. The introduction of the European Union (EU) regulation for safety barriers, which is based on performance, has encouraged European road agencies to perform an upgrade of t

Modeling the water isotopes in Greenland precipitation 1959–2001 with the meso-scale model REMO-iso

Ice core studies have proved thed18O in Greenland precipitation to be correlated to thephase of the North Atlantic Oscillation (NAO). This subject has also been investigated inmodeling studies. However, these studies have either had severe biases in thed18O levels,or have not been designed to be compared directly with observations. In this study wenudge a meso‐scale climate model fitted with stabl

Oxidative DNA damage in human lymphocytes : Correlations with plasma levels of α-tocopherol and carotenoids

In order to investigate whether oxidative damage is associated with differences in antioxidant intake, we measured the levels of 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) in lymphocytes and α-tocopherol and several carotenoids in plasma of women with different dietary habits. We found that women from Granada (Spain), a region with a typically Mediterranean diet, had significantly higher leve

Partiklar i atmosfären påverkar klimatet

Partiklar i atmosfären – aerosoler – har en avkylande effekt på jordens klimat. Aerosolernas sammanlagda effekt bedöms i IPCCs femte stora rapport, AR5, som något mindre än vad som rapporterades i 2007 i AR4. Partiklars avkylande effekt har troligen i viss mån motverkat växthusgasutsläppens uppvärmande påverkan. Vi kan dock inte förlita oss på sådan draghjälp i klimatarbetet. Internationella övere

Serum tau fragments as predictors of death or poor neurological outcome after out-of-hospital cardiac arrest

Background: Anoxic brain injury is the primary cause of death after resuscitation from out-of-hospital cardiac arrest (OHCA) and prognostication is challenging. The aim of this study was to evaluate the potential of two fragments of tau as serum biomarkers for neurological outcome. Methods: Single-center sub-study of 171 patients included in the Target Temperature Management (TTM) Trial randomly a

Lipases have similar water activity profiles in different reactions

The shape of the profiles of enzyme activity versus water activity for four different lipases were independent of the reaction used to determine the activity. The profile for each lipase (Rhizopus arrhizus, Pseudomonas sp., Candida rugosa and Lipozyme) in esterification, hydrolysis and transesterifications profiles were the same. In transesterification the yield was unaffected by the water activit

Molecular design and synthesis of hydroxide ion exchange membranes carrying alicyclic quaternary ammonium cations

Significantresearch efforts are currently directed towards the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers able to operate efficiently without platinum-groupmetal catalysts [1]. The grand challenge is to identify and synthesize polymeric AEM materials possessingthe necessary chemical and thermal stability. Studies o

Computerised perimetry

During the last few years computerised perimetry has become a clinical reality. This new technique eliminates the operator's error, ensures reproducibility of test procedures and parameters and makes visual field testing of large numbers of patients possible. Great differences exist between computerised perimeters. Differences in hardware for example, the way in which stimuli or field charts are p
