Cerebral white matter hyperintensities (WMHs) are central MRI markers of the brain aging process, but the mechanisms for its progression remain unclear. In this study, we aimed to determine whether the baseline serum cystatin C level represented one mechanism underlying WMH progression, and whether it was associated with the long-term progression of cerebral WMH volume in MRI. 166 consecutive i...

AIMS To investigate the reasonable dose of Voluven for rapid plasma volume expansion during the anaesthesia induction patients receiving gastrointestinal surgery. METHODS Sixty patients were randomly divided into three groups (n=20): Group A (5 ml/kg), Group B (7 ml/kg) and Group C (9 ml/kg). HES 130/0.4 was intravenously transfused at a rate of 0.3 ml/kg/min) at 30 min before anaesthesia ind...

in this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. in order that studies on different types of nanotubes be comparable, the chiral vectors of c and si-c nanotubes are selected as (7,7) and (5,5), respectively, so that    a similar volume of fluid is investigated ...

Relationship between coronary plaque progression , as determined by intravascular ultrasound (IVUS), and prospective risk for cardiovascular events has been proven by the analysis of six clinical trials 1). IVUS studies showed only a minimal improvement of atheroma volume with statin therapy 2). A meta-analysis of nine studies using virtual histology IVUS (VH-IVUS) imaging with 16 treatment arm...

In this paper the methodology of biplots is introduced as a means for monitoring the behaviour of process systems. This sophisticated methodology allows for the projection of high-dimensional data to a low-dimensional subspace that can be visualised by a human operator. The projections are highly graphical in nature, and rich in information regarding variation in process variables, correlations...
