Background: Arteriovenous malformations (AVMs) within the mediastinum are rare vascular anomalies. With the increasing number of coronary angiographies being performed, the number of incidentally found cases is rising. This presents challenges in terms of determining the appropriate treatment strategy.

Salicylaldehyde-based inhibitors have been reported to form stable imine adducts with the catalytic lysine of protein kinases. However, the targeted lysine in these examples is buried in a hydrophobic environment.

Spontaneous epidural haematoma (SEDH) is a rare complication of sickle cell disease (SCD). To our knowledge, 38 cases of patients with SEDH associated with SCD have been reported in the literature. In this case report we describe the first Danish paediatric case with SCD and SEDH.

Here, we introduce ferrous iron-activatable luciferin-1 (FeAL-1), a small-molecule probe for bioluminescent imaging of the labile iron pool (LIP) in luciferase-expressing cells and animals. We find that FeAL-1 detects LIP fluctuations in cells after iron supplementation, depletion, or treatment with hepcidin, the master regulator of systemic iron in mammalian physiology.
