Asymmetric flow field-flow fractionation for the monitoring of red wine colloids and macromolecules throughout the winemaking process

Frontiers in Soft Matter
Colloids and macromolecules are the major compounds in wine particulate matter and play an important role in many wine properties that change during the winemaking process. However, methodologies are lacking to characterize and quantify the changes these

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Cyclical magnetic field flow fractionation

Journal of Applied Physics, 2012
In this study, a new magnetic field flow fractionation (FFF) system was designed and modeled by using finite element simulations. Other than current magnetic FFF systems, which use static magnetic fields, our system uses cyclical magnetic fields. Results of the simulations show that our cyclical magnetic FFF system can be used effectively for the ...
