Selective coronary arteriography produces characteristic ST-T changes associated with significant axis shifts. In patients with normal control AQRS (mean, +88.60; SD -t12.20) left coronary injections induced an important leftward deviation of the AQRS: mean, +8.2.; SD, +49.10 (P < 0.001). Right coronary artery opacification changed the AQRS from a control mean of +66.50; SD, +17.20 to a mean of...

Of 114 patients with acute myocardial infarction admitted consecutively to a coronary care unit, 10 had recent antero-septal myocardial infarction associated with right bundle-branch block and obvious left axis deviation, and I had recent antero-septal myocardial infarction with right bundle-branch block and right axis deviation. Attention is drawn to the high mortality (7 out of 11 patients), ...

Sound localization is an important function of the human brain, but the underlying cortical mechanisms remain unclear. In this study, we recorded auditory stimuli in three-dimensional space and then replayed the stimuli through earphones during functional magnetic resonance imaging (fMRI). By employing a machine learning algorithm, we successfully decoded sound location from the blood oxygenati...

The aim of this paper was to verify if the growth of the nasomaxillary complex can be influenced by a purely functional alteration such as nasal obstruction, which was induced experimentally in a genetically controlled animal model. Sixty albino rats were employed. Twenty of them had the right nostril occluded by a synthetic resin; another twenty had both nostrils occluded; the other 20 were ta...

We show snapshots of magnetic flux lines in a simulated 10x10x150 nm iron pillar undergoing magnetization reversal in an applied magnetic field that makes an angle of 75 with the pillar's axis. Finite-temperature micromagnetics simulations were performed on an IBM SP3 supercomputer and the results visualized with the Tecplot graphics package. Red: the z-component of the magnetization, mz, orien...
