The delayed triple treatment may serve as an efficient therapy, which prevents brain insult propagation following sarin-induced refractory SE, even if treatment is postponed for up to 1 h.Peratrial balloon pulmonary valvotomy, an alternative technique for severe pulmonary valve stenosis (PVS) in infants, performed exclusively under transesophageal echocardiographic guidance is hereby described. The technique is performed using a hollow-probe via a right mini-thoracotomy in the fourth-intercostal space. The hollow- probe introduces a guidewire through PVS without touching the right ventricular wall, therefore, avoiding eliciting ventricular arrhythmias, spasm of right ventricular outflow tract, and subsequent hemodynamic instability. Unlike conventional approaches, peratrial technique permits quicker orientation, dilatation, and allows quick conversion to open-heart surgery when needed.Initial successes in developing small molecule ligands for non-coding RNAs have underscored their potential as therapeutic targets. More recently, these successes have been aided by advances in biophysical and structural techniques for identification and characterization of more complex RNA structures; these higher-level folds present protein-like binding pockets that offer opportunities to design small molecules that could achieve a degree of selectivity often hard to obtain at the primary and secondary structure level. More specifically, identification and small molecule targeting of RNA tertiary and quaternary structures have allowed researchers to probe several human diseases and have resulted in promising clinical candidates. In this review we highlight a selection of diverse and exciting successes and the experimental approaches that led to their discovery.
