Function of potential bypass tracts for atrioventricular conduction.
Function of potential bypass tracts for the atrioventricular conduction was examined in isolated rabbit hearts using microelectrodes, a suction electrode, and bipolar electrocardiographic leads. After the normal A-V conduction was blocked by acetylcholine, conduction to the ventricle occurred with a much shorter A-V conduction time and without significant QRS change, when a point at the root of...
متن کاملQUICKSELECT Revisited
We give an overview of the running time analysis of the random divide-and-conquer algorithm FIND or QUICKSELECT. The results concern moments, distribution of FIND’s running time, the limiting distribution, a stochastic bound and the key: a stochastic fixed point equation.
متن کاملPENDRED\'S SYNDROME REVISITED
Pendred's syndrome is defined as a triad of congenital perceptive hearing loss, goiter, and abnormal perchlorate test. Three brothers with Pendred's syndrome [P.S.] are reported. The oldest brother has hearing loss (he has been deaf and mute since childhood) and has a large goiter. A thyroid scan revealed euthyroid multinodular goiter and a perchlorate test was performed, and reported abno...
متن کاملKinetics of DNA duplex formation: A-tracts versus AT-tracts.
The hybridisation and melting of DNA strands are critical steps in many biological processes, but still a deeper understanding of the kinetics is lacking. This is evident from the absence of a clear correlation between rate constants for duplex formation and the number of bases in the strand or the sequence. Here we have probed differences between formation times of A-tracts and AT-tracts by st...
متن کاملUSHER\'S SYNDROME REVISITED
Usher's syndrome is a genetically inherited autosomal recessive disorder resulting in the double handicap of deafness and progressive blindness, known as retinitis pigmentosa. The disease is also associated with psychoses, mental retardation, and other major neurophysiological changes. It appears to be more common among Jewish individuals and consanguinous marriages. While it is rare in th...
