The gamma-aminobutyric acid type B (GABAB) receptor is an allosteric complex made of two subunits, GABAB1 (GB1) and GABAB2 (GB2). Both subunits are composed of an extracellular Venus flytrap domain (VFT) and a heptahelical domain (HD). GB1 binds GABA, and GB2 plays a major role in G-protein activation as well as in the high agonist affinity state of GB1. How agonist affinity in GB1 is regulated...

Fast and very fast transient overvoltages generally appear during switching operations within electrical substations. The oscillatory nature of such phenomena with frequencies that can reach several tens megahertz tends to degrade the lifetime high voltage equipment as bushings transformers, inducing partial discharges activity or breakdown insulation system. According case studies, are one mos...

The ventricular fibrillation threshold (VFT) was measured in 28 patients at the time of cardiac surgery. The VFT was measured with a 100 Hz train of 24 rectangular pulses positioned across the ST segment and T wave. Current was applied to the epicardial surface of either ventricle with a bipolar electrode probe. In six patients, the normal right VFT was 24.3 +/- 5.2 mA, and in 10 patients the n...

UNLABELLED Verbal Fluency Tests (VFT) are commonly used to assess executive functions and language in clinical and epidemiological studies. These tests were included to access cognitive function and predictors to its decline in ELSA-Brasil (Longitudinal Study of Adults' Health), a cohort that investigates incidence and predictors of chronic diseases among 15,000 civil servants from six public e...

This paper develops a boundedly rational version of variable frame theory (VFT) of Bacharach [B93] by merging the variable frame conceptual apparatus with the leveln theory (LNT) of Stahl and Wilson [SW95]. A fundamental feature of VFT is that a player’s options are determined by her ‘frame’: one ‘option’ is associated to each cell of a frame-induced partition of the actions. Coupled with the p...

Virtual Reality (VR) has gained more importance in the educational sector. A possibility of using VR education can be Field Trips (VFTs). This work analyses possibilities creating VFTs with different software/tools, output devices, and 360° cameras The preparatory work, recording own images, is described, including involved time comparison cameras. With a comparison, four categories software/to...

The relation between ventricular fibrillation threshold (VFT) and cardiac surface QRST area distributions was studied in eight pentobarbital-anesthetized dogs. Unipolar epicardial electrograms were recorded from 64 sites evenly distributed on the right and left ventricles. Localized areas of short repolarization properties were produced by directing five intensities of light onto the surface of...
