- This study looked into the occurrence of exercise-associated muscle cramps (EAMC) among athletes competing in ultraendurance events, specifically at the IRONMAN World Championship from 1989-2019.
- A total of 10,533 medical records were analyzed, finding that 2863 participants experienced EAMC, with dehydration, exhaustion, and previous cramping evaluations being key risk factors.
- The study concluded that while dehydration is linked to cramping, electrolyte imbalances (like low serum sodium or potassium) are not, which challenges some existing beliefs in the field.*
The development of the most comprehensive universal calibration of molar mass dependences will be presented. For the first time, diffusion-ordered spectroscopy (DOSY) can now provide structure-, solvent-, and temperature-independent molar mass determinations for both small and large molecules. This fundamental theoretical approach provides only one single function which could perfectly describe all molar mass dependences.

This new hyphenation approach facilitated the simultaneous separation of a polymer mixture and the determination of molar masses within a single 3D experiment. The online coupling of High-Performance Liquid Chromatography (HPLC) and two-dimensional DOSY-NMR will be called 3D-LAC-NMR-DOSY experiment.

Interpreting NMR experiments benefits from first-principles predictions of chemical shifts. Reaching the accuracy limit of theory is relevant for unambiguous structural analysis and dissecting theoretical approximations. Since accurate chemical shift measurements are based on using internal reference compounds such as trimethylsilylpropanesulfonate (DSS), a detailed comparison of experimental with theoretical data requires simultaneous consideration of both target and reference species ensembles in the same solvent environment.
