Abstract: Abstract Above and belowground compartments in ecosystems are closely coupled on daily to annual timescales. In mature forests, this interlinkage and how it is impacted by drought is still poorly understood. Here, we pulse‐labelled 100‐year‐old… read more here.

Abstract: BACKGROUND Urinary 5-hydroxyindoleacetic acid (5-HIAA) is a first line investigation for gastrointestinal neuroendocrine tumours (NETs) that secrete serotonin. It also has clinical utility for monitoring disease progression and therapeutic response. AIM To develop and validate… read more here.

DOI: 10.3390/ph14040327
Abstract: Hyperpolarized 13C magnetic resonance imaging often uses spin-echo-based pulse sequences that are sensitive to the transverse relaxation time T2. In this context, local T2-changes might introduce a quantification bias to imaging biomarkers. Here, we investigated… read more here.
