An evidence for a potassium channel in endoplasmic reticulum based on single channel recording in bilayer lipid membrane
Introduction Numerous studies have demonstrated the presence of potassium selective channels in membranes internal organelles. These channels are essential to a large variety of cellular processes including intracellular 2+ a signaling, protein recycling, charge neutralization and cell protection. In contrast to the sarcoplasmic reticulum + here potassium channels have been clearly ...
متن کاملSingle-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
متن کاملCharacterization of biophysical properties of single chloride channel in rat brain mitochondrial inner membrane by channel incorporation into bilayer lipid membrane
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...
متن کاملA bedside computer in foetal assessment.
process. 1. The Foetal Electrocardiogram: The examination of the FECG by the traditional methods of cardiology have proved very disappointing and unrewarding. If, however, the FECG is merely used as a means of recording the beat-to-beat interval of the foetal heart, statistical evaluation of this information can yield a valuable prognostic index. 2. The Foetal Ballistocardiogram: The purpose of...
متن کاملA method of securing the direct body ballistocardiogram by means of a microscope, giving a record readily calibrated.
We describe a simple method of recording the direct body ballistocardiogram by means of a microscope and a powerful light source. The beam passes through a slit attached to the body, and the image of this moving slit is magnified by the microscope and focused on moving photographic paper. When a static force is applied to the body, the base line of the record is permanently displaced and so the...
