Sensitized Triplet-Triplet Annihilation in Nanostructured Polymeric Scintillators Allows for Pulse Shape Discrimination.

Scintillating materials emit light when exposed to ionizing radiation or particles and are used for the detection of nuclear threats, medical imaging, high-energy physics, and other usages. For some of these applications, it is vital to distinguish neutrons and charged particles from γ-rays. This is achievable by pulse shape discrimination (PSD), a time-gated technique, which exploits that the scintillation kinetics can depend on the nature of the incident radiation.

Direct cardiac involvement in childhood hemolytic-uremic syndrome: case report and review of the literature.

Unlabelled: Overhydration, hypertension, anemia, or dyselectrolytemias sometimes cause cardiovascular impairment in childhood hemolytic-uremic syndrome. Here, we report the case of a 4.5-year-old boy with hemolytic-uremic syndrome and sudden onset, 6 h later, of hemodynamic compromise secondary to a cardiac thrombotic micro-angiopathy.
