Quick home test for Parkinson's medication adjustment: Detection of L-DOPA in blood using enzyme colorimetry
Parkinson's disease is a neurological disorder that primarily affects motor performance. L-DOPA is the precursor of dopamine (DA) synthesis in the body and is widely used in the treatment of Parkinson's disease. However, because of the side effects associated with these drugs, clinical adjustments to the medication are often required. Therefore, measuring the concentration of L-DOPA in patients is an issue of interest for many researchers. Several methods have been developed to detect the concentration of L-DOPA, such as electrochemical assay and liquid chromatography, but there are still some limitations. In this study, a simple enzymatic colorimetric method was developed to selectively identify and oxidize L-DOPA by oxidative enzymes, resulting in a yellow product that can be identified by the naked eye; the concentration of L-DOPA can be inferred from the color intensity. Therefore, it can be used as a quick and easy estimation of the L-DOPA concentration in the test body, which is expected to be used as an indicator and reference for drug formulation.2022.1016
Dept. of Special Education Designs A8M Digital Learning Tool for Students in Need
October 15th is the White Cane Safety Day, the Day of the Blind. In order to reduce the learning difficulties of blind students in mathematics, Associate Professor Chien-Huey Sophie Chang of the Department of Special Education of NTNU led a team to develop the "A8M Digital Learning Tool" which is convenient for visually impaired students to read and write mathematics. It is easy to use and enables teachers to communicate well with visually impaired students. Users can listen and read repeatedly with a Braille display, which makes it easier to grasp the structure of complex mathematical formulas.2022.0922
Detecting the size of primordial black holes with superhorizon perturbations
At the onset of the cosmic journey, the inflationary mechanism produced superhorizon curvature perturbations which affected the future formation of the universe. This study analyzed the growth of superhorizon curvature perturbations in the inflationary universe. Using a simple ultraslow-roll model, we derived the coherence function between any two points in the curvature perturbation. It showed that the causality limits the growth of the curvature perturbation, thereby constraining the important inflationary slow-roll parameters, allowing the universe to produce a large enough primordial black hole. Our research will help estimate how curvature perturbations form primordial black holes in the universe.2022.0725
