    This paper presents preliminary results obtained from a mathematical model of intracardiac electric field plethysmography. This method is based on measurement of the electrical field inside the heart with excitation applied laterally to both sides of the thorax. Two models have been examined. The first one was the spherical shell embedded in conductive medium. The second one has been constructed u... View full abstract»

    The authors have used a computer model of the ventricular action potential to study conditions in which EADs developed in an area of ventricular myocardium can propagate to other areas, generating ectopic activity. They simulate the interactions between two areas of myocardium; one of them can develop EADs while the other is kept under normal conditions. Both zones are coupled through an area of i...

    The possibilities of electrical measurement of the human body in the direction of depth using microwaves are discussed both theoretically and experimentally. By measuring the input impedance of an open-ended coaxial probe radiating into bilayered medium, both the depth of fat layer and the electrical surface impedance of muscle layer can be estimated. From the calculated input impedance using a fu... View full abstract»

    Exposure to extremely low frequency magnetic fields (ELFMF) of 50 Hz and 400 mT induced mutations in the hypoxanthine-guanine phosphoribosyl transferase gene of human melanoma MeWo cells. The mutation frequency was enhanced both by increasing the exposure period and the induced current intensity. DNA replication error is suspected to cause the mutations produced by ELFMF exposure View full abstract»

    This paper gives a brief explanation of event related brain potentials (ERPs) within an electroencephalogram (EEG) and discusses a method for their clear detection. An ERP is evoked as an inner psychological response to an outward physical stimulus. Basically, one is able to know when another person has a greater interest in one of various targets by detecting the ERP. The ERP appears from about 1... View full abstract»

    For optimizing medical applications, it is important to understand how, and to what extent, the electromagnetic field propagates inside a living-tissue configuration. Therefore, the electromagnetic field excited by a current pulse in a circular loop has been calculated for a model of plane-stratified biological tissues. To incorporate the effects of dispersion in the configuration, permittivity mo... View full abstract»

    During the dialytic treatment, plasma phosphate (Pi) has a very specific time course. It reaches a nadir value approximately 90 minutes after the beginning of the treatment and then, despite the ongoing removal, it exhibits either a constant steady state or a slow rebound. In order to quantitatively describe the kinetics, the authors have proposed a set of different compartmental control models, w... View full abstract»
