Hyperpolarization current (I(f)) is an important player in controlling heart rate and is stimulated by cAMP and inhibited by members of the pertussis toxin-sensitive G-protein G(i)/G(o) family. We have successfully derived cardiocytes from embryonic stem cells lacking G(o) or G(i2) and G(i3). We have established that both basal and isoproterenol-stimulated activities of I(f) in these cardiocyte...

In this study, samples were taken of coastal waters of Kiashahr port. Magnetic desalination consisted of exposing the sample to a Magnetic field and putting the water in physical contact with magnetic nanoparticles which were synthesized with the co-precipitation method. X-ray diffractometer, Fourier transform infrared spectroscopy and field-emission scanning electron microscopy were used for t...

We consider the problem of estimating the gains and phases of the RF channels of a M-element transmitting array, based on a calibration procedure where M orthogonal signals are sent through M orthogonal beams and received on a single antenna. The received data vector obeys a linear model of the type y 1⁄4 AFg þ n where A is an unknown complex scalar accounting for propagation loss and g is the ...
