LOCOMOTION IS ARGUABLY one of the most ubiquitous and important manifestations of life, equally important to feeding as to escape predators. Evolution came up with three molecular motors to power motion: the actomyosin system Levitsky (11); the microtubule, dynein-based flagellar motors of eukaryotes (13); and the flagellar rotary motors of bacteria (15). All three systems serve propulsion, i.e...

Torsade de pointes (Tdp) is a polymorphic ventricular tachycardia (VT) in which the axis of the QRS complex changes direction after a certain number of complexes as if the complex rotated around the baseline. Tdp is usually associated with QT prolongation, and dispersion of ventricular repolarlization (DR). Experimental models of tdp are usually associated with induction of early after depolari...

Despite the great advances that have occurred in the century following the first description of a Lynch syndrome (LS) family and more especially, in more than 20 years since the discovery of causal mutations in the mismatch repair genes (MMR), long-standing clinical questions remain unanswered. Moreover, as a result of novel technologies, new questions have arisen. With this commentary, we aim ...
