活细胞和液体中水的集体动力学。新的物理模型和生物学推论

Collective dynamics of water in the living cell and in bulk liquid. New physical models and biological inferences

Eugen A. Preoteasa, Marian V. Apostol

摘要:

在水中集体动力学的框架下,建立了基于元激发和长程电磁相互作用的细胞和液体模型。利用水相干域(CD)的低有效质量,我们研究了简单量子模型与细胞特征的相关性。研究了CD玻色型凝聚的假设、具有不可穿透壁和半穿透壁的球形阱中的CD模型以及由两个相互作用的CD组成的各向同性振子模型。估计的细胞体积与中型细菌和小型原核生物以及真核细胞中的一些细胞器相匹配。并对重水对真核生物的细胞毒性效应进行了解释。在另一种方法中,我们提出了一个类等离子体模型的氢氧离子等离子体在液态水。除了等离子体激元振荡,该模型预测了类似声音的非平衡元激发,我们称之为密度(水的声音异常),蒸发热和介电常数色散,与实验数据一致。在活细胞中由离子等离子体振荡产生的场可以支持长距离的细胞间关联。

英文摘要:

In the frame of collective dynamics in water, models built on elementary excitations and long-range electromagnetic interactions in the cell and bulk liquid are presented. Making use of the low effective mass of water coherence domains (CDs), we examined the relevance of simple quantum models to cellular characteristics. A hypothesis of CDs Bose-type condensation, and models of CD in spherical wells with impenetrable and semipenetrable walls, and of an isotropic oscillator consisting of two interacting CDs were investigated. Estimated cellular volumes matched to medium-sized bacteria and small prokaryotes, and to some organelles in eukaryotic cells. Also, the cytotoxic effects of heavy water in eukaryotes were explained. In another approach we proposed a plasmon-like model of hydrogen-oxygen ionic plasma in liquid water. In addition to plasmonic oscillations, the model predicted sound-like non-equilibrium elementary excitations that we called densitons (the sound anomaly of water), the vaporization heat and the permittivity dispersion, in agreement to experimental data. The fields generated by ionic plasma oscillations in living cells may support long distance intercellular correlations.
