Aminomethylation of spruce tannins and their application as coagulants for water clarification

Separation and Purification Technology, 2020
This study explored the potential for using tannin extract from spruce bark (Picea abies) as a coagulant. Spruce tannins were extracted with hot water and pulverized through spray drying and freeze drying.

POT1-TPP1 binding stabilizes POT1, promoting efficient telomere maintenance

Computational and Structural Biotechnology Journal, 2022
Telomeric POT1-TPP1 binding is critical to telomere maintenance and disruption of this complex may lead to cancer. Current data suggests a reduction of intracellular POT1 levels in the absence of TPP1.
