Introduction: Recent studies have shown the presence of Cl- channels in heart and liver mitochondrial membranes. In this work, we have characterized the functional profile of a Cl- channel from rat brain mitochondria. Methods: After removing and homogenizing the rat brain, the supernatant was separately centrifuged in MSEdigitonin, H2O and Na2CO3 and mitochondrial inner membrane vesicles wer...

Introduction: Different ATP-sensitive potassium channels have been detected in the mitochondrial inner membrane of cells. They are suggested to be involved in cell processes including cell protection. Here, we characterized the biophysical and electropharmacological properties of a KATP channel in the brain mitochondrial inner membranes. Methods: After removing and homogenizing the rat brain...

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...
