Are physiological oscillations physiological?
The Journal of Physiology, EarlyView., 2023 Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Sustainability in Analytical Chemistry Illustrated by Pharmaceutical Nitrosamine Testing
ELECTROPHORESIS, EarlyView.ABSTRACT Following the valsartan scandal in 2018, the testing of drug substances and drug products for N‐nitrosamines has become a critical and mandatory quality control measure. The European Pharmacopoeia chapter 2.5.42 currently describes three analytical methods for this purpose: HPLC–MS/MS, GC–MS, and GC–MS/MS.
