摘要翻译:
本文对磁场产生的生物效应进行了分析,以阐明磁场产生生物效应的物理机制。我们表明,这些机制之间存在着一种宗教性,它们之间的相互影响可以导致协同作用的结果。特别地,我们分析了磁场对生物体内孤子介导的氧化还原过程中电荷输运的生物学效应。这种孤子是由非线性方程组描述的,代表了由于中等强的电子-晶格相互作用而自捕获在α螺旋多肽中的电子。它们代表了低维系统中一种特殊类型的无分裂的大极化子。我们证明了孤子的有效质量不同于自由电子的质量,磁场对孤子的动力学以及伴随光合作用和呼吸作用的电荷输运有共振效应。这些效应可以导致磁场对氧化还原过程的非热共振效应,尤其是对生物体的新陈代谢的非热共振效应。这可以解释基于施加磁场的治疗的物理机制。

英文摘要:
In this paper, we analyze biological effects produced by magnetic fields in order to elucidate the physical mechanisms, which can produce them. We show that there is a chierarchy of such mechanisms and that the mutual interplay between them can result in the synergetic outcome. In particular, we analyze the biological effects of magnetic fields on soliton mediated charge transport in the redox processes in living organisms. Such solitons are described by nonlinear systems of equations and represent electrons that are self-trapped in alpha-helical polypeptides due to the moderately strong electron-lattice interaction. They represent a particular type of disssipativeless large polarons in low-dimensional systems. We show that the effective mass of solitons in the is different from the mass of free electrons, and that there is a resonant effect of the magnetic fields on the dynamics of solitons, and, hence, on charge transport that accompanies photosynthesis and respiration. These effects can result in non-thermal resonant effects of magnetic fields on redox processes in particular, and on the metabolism of the organism in general. This can explain physical mechanisms of therapies based on applying magnetic fields.
