Toward Harmonizing Quantification of Dopamine Neuron Imaging Biomarkers in Parkinson's Disease: The Centamine Scale

Annals of Neurology, EarlyView.
Objective Dopaminergic imaging is a key biomarker for both the investigation of the biology of Parkinson's disease and related synucleinopathies and the evaluation of potential therapies in clinical trials. This work presents a harmonized approach for quantifying dopaminergic molecular imaging tracers, such as [123I]ioflupane (dopamine transporter scan

Technical Efficiency and Cost Implications of No‐Cook Versus Traditional Alcohol Production Technologies at Household Scale

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In Vietnam, traditional distilled rice alcohol is often produced at the household scale with limited sanitary conditions, leading to low yield, unstable, and moderate‐quality alcohol products. No‐cook or Simultaneous liquefaction, saccharification, and fermentation (SLSF) technology has shown to be very promising thanks to its advantages such ...
