1. Impacto dos desvios de tensão de limiar induzidos por radiação ionizante no desempenho dos blocos básicos de dois amplificadores operacionais complementares
Este trabalho estuda os efeitos de dose total ionizante (TID ¿ Total Ionizing Dose) em amplificadores operacionais e em seus blocos básicos de construção. A radiação ionizante presente no espaço pode afetar o funcionamento das estruturas MOS, sendo que um dos parâmetros mais prejudicados é a tensão de limiar (Threshold Voltage). Em virtude da difer

2. On the nature of anomalous rectification in thalamocortical neurones of the cat ventrobasal thalamus in vitro.
1. Intracellular sharp electrode current clamp and discontinuous single electrode voltage clamp recordings were made from thalamocortical neurones (n = 57) of the cat ventrobasal thalamus in order to investigate the mechanism underlying anomalous rectification. 2. Under current clamp conditions, voltage-current (V-I) relationships in a potential range of -55

3. Role of sodium-calcium exchange in activation of contraction in rat ventricle.
1. The functional role of reverse Na(+)-Ca2+ exchange in the activation of contraction of rat ventricular myocytes has been studied. Mechanical activity of single cells, measured as unloaded cell shortening, was recorded simultaneously with membrane current and voltage using a single microelectrode voltage clamp and a video edge detection device. 2. The volt

4. A voltage-gated potassium channel in human T lymphocytes.
Human peripheral T lymphocytes were studied at 20-24 degrees C using the gigaohm seal recording technique in whole-cell or outside-out patch conformations. The predominant ion channel present under the conditions employed was a voltage-gated K+ channel closely resembling delayed rectifier K+ channels of nerve and muscle. The maximum K+ conductance in ninety
