Article Synopsis
  • - The study investigates how low potassium levels (hypokalemia) affect the electrical behavior of the heart's left ventricle in rabbits, particularly focusing on ventricular repolarization and the potential risk for dangerous heart rhythms (malignant ventricular arrhythmia).
  • - Twenty rabbits were divided into control (normal potassium) and hypokalemic groups to test differences in electrical properties like action potential duration and ventricular fibrillation threshold, revealing significant alterations in the hypokalemic group.
  • - Results showed that hypokalemia prolonged repolarization duration and reduced the voltage required to induce fibrillation, indicating an increased risk for serious heart arrhythmias, especially associated with changes in specific protein expression related to heart muscle function.

InAs/GaAs(001) quantum dots grown by droplet epitaxy were investigated using electron microscopy. Misfit dislocations in relaxed InAs/GaAs(001) islands were found to be located approximately 2 nm above the crystalline sample surface, which provides an impression that the misfit dislocations did not form at the island/substrate interface. However, detailed microscopy data analysis indicates that the observation is in fact an artefact caused by the surface oxidation of the material that resulted in substrate surface moving down about 2 nm.
