Article Synopsis
  • The study investigates how reallocating time among physical activity, sedentary behavior, and sleep affects obesity indicators like BMI and waist circumference across various age groups.
  • Researchers analyzed data from 9,818 participants using isotemporal substitution models to understand the implications of these behavior changes.
  • Results indicated that even small shifts of 10-30 minutes can significantly impact obesity, with reallocating moderate-to-vigorous physical activity (MVPA) to lighter activities or sedentary behavior having particularly detrimental effects.

Post expression from the host cells, biotherapeutics undergo downstream processing steps before final formulation. Mass spectrometry and biophysical characterization methods are valuable for examining conformational and stoichiometric changes at these stages, although typically not used in biomanufacturing, where stability is assessed via bulk property studies. Here we apply hybrid MS methods to understand how solution condition changes impact the structural integrity of a biopharmaceutical across the processing pipeline.
