Subcellular ToF-SIMS Imaging of the Snow Alga by Combining High Mass and High Lateral Resolution Acquisitions.

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) imaging has demonstrated great potential for metabolic imaging; however, achieving sufficiently high lateral and mass resolution to reach the organelle scale remains challenging. To address this, we have developed an approach that combines imaging acquisitions close to the highest lateral resolution (<150 nm) and mass resolution (9,000) reachable by ToF-SIMS. The data were then merged and processed using multivariate analysis (MVA), providing the identification and annotation of 85% of the main contributors to the multivariate analysis components at high lateral resolution.

[Promoting physical activity in everyday life: the role of health care professionals].

Physical activity (PA) promotion has become a central objective of Public Health Organisations, due to its long-lasting global benefits on health. The 2023 recommendations recommend at least 150 minutes of moderate physical activity or 75 minutes of intense physical activity per week for adults. New approaches focus on physical exercise as an integral part of daily life.

Importance of Sex-Dependent Differences for Dosing Selection and Optimization of Chemotherapeutic Drugs.

Background: Despite major advances in cancer treatment in the past years, there is a need to optimize chemotherapeutic drug dosing strategies to reduce toxicities, suboptimal responses, and the risk of relapse. Most cancer drugs have a narrow therapeutic index with substantial pharmacokinetics variability. Yet, current dosing approaches do not fully account for the complex pathophysiological characteristics of the patients.
