Background: The symptoms and associated characteristics of attention-deficit/hyperactivity disorder (ADHD) are typically assessed in person at a clinic or in a research lab. Mobile health offers a new approach to obtaining additional passively and continuously measured real-world behavioral data. Using our new ADHD remote technology (ART) system, based on the Remote Assessment of Disease and Relapses (RADAR)-base platform, we explore novel digital markers for their potential to identify behavioral patterns associated with ADHD.

Identifying metabolites in NMR-based plant metabolomics is challenging due to the complexity of plant metabolites. This complexity stems from the abundance and diverse chemical properties of compounds, which vary in concentration across plant specimens. Additionally, the lack of automated identification software complicates the analysis process.

Flavonoids are a group of specialized metabolites that are ubiquitously found within the plant kingdom. While they fulfill various important functions within the plant, they are also utilized by humans in a variety of different fields such as medicine, food science, and agriculture. Thus, to elucidate the chemical composition of any given plant extract, extraction and identification of flavonoids are of high interest.
