The Influence of a Static Magnetic Field on the Behavior of a Quantum Mechanical Model of Matter

The authors describe and verify the growth characteristics of simple tissue structures in relation to a present external magnetic field; the results of the research are to clarify the effects of magnetic (geomagnetic) field changes on such cultures. Although the first biological experiments showed that, in the given sense, magnetic fields do exhibit certain statistically significant influence, the question remained of what tools and model parameters are applicable for the description of a complex system embodied in, for example, even a very simple tissue structure. The referenced papers present various approaches to and aims of the investigation of an external magnetic field on the surrounding environment. Roda [2] described the very specific influence of a stationary magnetic (50 µT) and an electromagnetic (6 µT, 50 Hz) field on animal tissues as regards their ability to stimulate or restrain antioxidative enzymes. The effects of stationary gradient magnetic fields (4,3 T/m) on the growth of eukaryotic organisms are discussed in article [3]; the related experiments showed that although the speed and growth phase of the exposed population of Paramecium caudatum do not differ significantly from those observed in check populations, a major negative decrease (by 10.5% to 12.2%) occurs in both the time necessary for the maximum growth of the organism and the number of individuals in a colony (10.2% - 15.1%). Paper [2] presents the conclusions obtained from experiments targeting the influence of a pulse magnetic field (10µT and 100 Hz, with the duty cycle of 2:1 and period of 1s) on fertilized eggs of domestic fowl (Gallus domesticus). After 15 days of the experimental cycle, the exposed embryos exhibited a higher somatic weight and a more advanced stage of development than their control counterparts; at 21 days into the experiment, the somatic weight and stage of development were lower in the exposed embryos than in the control ones. The difference is not discernible in embryos that have been exposed to a magnetic field with harmonic waveform of the frequency of 50 Hz. The experiment [4] proposes that the action of a magnetic field (480 mT) on samples of maize (Zea mays L.) sown in a substrate increases the growability, growth in percent, and weight of the dry sample; however, under action of the magnetic field, the growth of the given type of seed differs depending on its genetic variability. According to an earlier study [5], a strong external magnetic field introduces a basic anisotropy into incompressible magnetohydrodynamic turbulence. The conclusion is reached that the turbulent spectrum splits into two parts: an essentially twodimensional spectrum with both the velocity field and magnetic fluctuations perpendicular to the magnetic field, and a generally weaker and more nearly isotropic spectrum of Alfven waves. The discussed paper [5] comprises an elementary evaluation of the properties of a dynamic environment; the influence of an external magnetic field on a biological system including nanoparticles is then analyzed, together with the activation of such a system, in article [6]. In this context, let us note that activated platelets play a pivotal role in cardiovascular diseases such as atherothrombosis. Thus, strategies enabling activated platelet molecular imaging are of great interest; herein, a chemical protocol was investigated for coating superparamagnetic iron oxide nanoparticles with low molecular weight fucoidan, a ligand of P-selectin expressed on the surface of activated platelets.
