Catalytic Wheel, Brownian Motor, and Biological Energy Transduction
Tian Yow Tsong and Cheng-
An enzyme turns over, or recycles during each catalytic process. It is a catalytic wheel, analogous to a motor, or an engine. The fuel, or the driving force for the wheel, is the free energy of the substrate (S) to product (P) conversion (GR), or a free energy output of a coupled chemical reaction. When GR of the S -
RF Interaction Mechanisms

Qualitative description of interaction mechanisms, particularly those published in the last four years or so. Variety of mechanisms proposed. Some seem unlikely to lead to biological effects for f~1 GHz. For others the position is less clear. Thermal effects could be age dependent although still unlikely to be significant below guidelines.

From recent experimental results we deduce a physical model of the cell membrane [21]. The transparent range, stretched from 0.22 to 0.9 ?m, is located between two absorbing ranges. Four resonance wavelengths of the cell membrane are chosen to be in good agreement with the experimental results. Physical theories are used to calculate the membrane complex index of refraction. The cell membrane permeability appears following its transmission coefficient which has been found. The high value of the radiation pressure calculated inside the membrane due to pulsated infrared light could explain the acceleration of the CVcells microtubules array disassembly. The theory explains the increasing of the mitochondria fluorescence irradiated with an ultraviolet light. Then a physiological or artificial low frequency signal due to one nervous fiber diffraction, acting upon ions, could produce an ionizing radiation in UV spectrum.

We present a quantic theory to explain the "spontaneous" and the "induced" emissions of the ions whose photon energies are following a radioactive decreasing law in the ultraviolet, visible and infrared spectrum. These emissions are due to solitary-
The spectral energy density inside the living matter depends on the plasma characteristics, the modulation frequency of the carrier wave, and the distance from the device. As we know the dipolar transition electric moment we determine both the probability of the "spontaneous" emission and with the spectral energy density the probability of "induced" emission. We can deduce the fundamental lifetime of the photons. Furthermore the number of the photons by unit of area is calculated. It depends on the modulation frequency, the spectral energy density, and its wavelength. In UV spectrum, for an efficient "induced" emission the modulation frequency has to be high. In that case, with our device the photon lifetime and the used irradiation exposure are of the same order.
Our results are in good agreement with two recent published experiments. In one of them, some authors have shown specific effects, in a near environment, of alternating electric fields applied with two insulated electrodes. For some days of application the proliferation of malignant cells in culture, and tumors growing in mice, were inhibited.
In the order, the biophoton density measured in the optical spectrum and spontaneously emitted by all living systems are in good agreement with our generated photon density evaluation. We can say the "induced" Ultraviolet emission by the ions in the living matter due to our external plasma device can interfere with the biophotons emitted by the DNA.

An Approach to Electrical Modeling of Single and Multiple Cells
Thiruvallur R. Gowrishankar and James C. Weaver -
Previous theoretical approaches to understanding effects of electricon cells have used partial differential equations such as Laplace’s equation and cell models with simple shapes. Here we describe a transport lattice method illustrated by a didactic multicellular system model with irregular shapes. Each elementary membrane region includes local models for passive membrane resistance and capacitance, nonlinear active sources of the resting potential, and a hysteretic model of electroporation. Field amplification through current or voltage concentration changes with frequency, exhibiting significant spatial heterogeneity until the microwave range is reached, where cellular structure becomes almost ‘‘electrically invisible." In the time domain, membrane electroporation exhibits significant heterogenetity but occurs mostly at invaginations and cell layers with tight junctions. Such results involve emergent behavior and emphasize the importance of using multicellular models for understanding tissue-

The DNA molecule, well known from biology for containing the genetic code of all living species, has recently caught the attention of chemists and physicists. A major reason for this interest is DNA’s potential use in nanoelectronic devices, both as a template for assembling nanocircuits and as an element of such circuits. Without question, a truly conducting form of DNA would have a major impact on developments in nanotechnology. It has also been suggested that extended electronic states of DNA could play an important role in biology, e.g., through the processes of DNA damage sensing or repair or through long-

The frequency dependence of phospholipid vesicle shapes in an external electric field
Primoz Peterlin, Saša Svetina, Bostjan Zeks -
Experiments show that phospholipid vesicles exposed to AC electric field undergo a shape transition from prolate to oblate ellipsoidal shape when the frequency of the field is increased. In a theoretical model that has been devised to explain this phenomenon for nearly spherical vesicles, the vesicle shape is determined by the minimization of the total free energy of the vesicle. The two contributions to the total free energy are the membrane bending energy and the energy of the electric field. The model exhibits the same frequency-

Cell Membrane Electropermeabilization with Arbitrary Pulse Waveforms
Karel Flisar, Marko Puc, Tadej Kotnik, and Damijan Miklancic -
Exposure of a biological cell to an electric field can produce a variety of responses. If the field strength exceeds a certain threshold value, this leads to a large transient increase in membrane conductivity and permeability for ions and molecules (electropermeabilization, often also named electroporation) or to fusion of adjacent cells (electrofusion). Nowadays, these phenomena are widely used in applications such as gene transfection, preparation of monoclonal antibodies, and drug delivery, especially in electrochemotherapy of tumors. For optimal effectiveness of these applications, one must choose the most appropriate, amplitude, duration, and waveform of the applied electric pulses. With 2mm distance between plate electrodes, which is an established setup for electropermeabilization in vitro, the threshold voltages typically range from 120 to 300 V, with pulse durations from several microseconds to several milliseconds. Due to these demands, electropermeabilization is performed using specialized devices, often referred to as electroporators or electropulsators. Today, several such devices are commercially available, delivering either exponential or unipolar rectangular pulses with adjustable duration and amplitude. Often, the number of pulses and the intervals in which they are delivered can also be chosen.

Measuring Effects of Music, Noise, and Healing Energy Using a Seed Germination Bioassay
KATHERINE CREATH, Ph.D., and GARY E. SCHWARTZ, Ph.D. -
Objective: To measure biologic effects of music, noise, and healing energy without human preferences or placebo effects using seed germination as an objective biomarker.
Methods: A series of five experiments were performed utilizing okra and zucchini seeds germinated in acoustically shielded, thermally insulated, dark, humid growth chambers. Conditions compared were an untreated control, musical sound, pink noise, and healing energy. Healing energy was administered for 15–20 minutes every 12 hours with the intention that the treated seeds would germinate faster than the untreated seeds. The objective marker was the number of seeds sprouted out of groups of 25 seeds counted at 12-
Results: Musical sound had a highly statistically significant effect on the number of seeds sprouted compared to the untreated control over all five experiments for the main condition (p , 0.002) and over time (p ,0.000002). This effect was independent of temperature, seed type, position in room, specific petri dish, and person doing the scoring. Musical sound had a significant effect compared to noise and an untreated control as a function of time (p , 0.03) while there was no significant difference between seeds exposed to noise and an
untreated control. Healing energy also had a significant effect compared to an untreated control (main condition, p , 0.0006) and over time (p , 0.0001) with a magnitude of effect comparable to that of musical sound.
Conclusion: This study suggests that sound vibrations (music and noise) as well as biofields (bioelectromagnetic and healing intention) both directly affect living biologic systems, and that a seed germination bioassay has the sensitivity to enable detection of effects caused by various applied energetic conditions.
Studies on the Interaction Between Electromagnetic Fields and Living Matter Neoplastic Cellular Culture
Suleyman Seckiner Gorgun, Collegno, Italy -
The study of the interactions between electromagnetic fields and living matter has become a fertile field for research in the last century, even though these phenomena have been empirically observed by various civilisations since ancient times. Considerable experimental evidence today points to the possibility of modulating biological functions and structures in a controlled way by applying electromagnetic fields and, vice versa, the possibility of detecting and measuring endogenous electrical currents in living organisms and their components

Fröhlich System with Modulated Access to Pumping Source
Fedor Šrobár, Institute of Radio Engineering and Electronics, Division of Materials, Academy of Sciences of the Czech Republic, Praha, Czech Republic -
Vibrating polar molecular entities in biological cell's interior can emit radiation. Fröhlich postulated rate equations for occupancy of the vibration modes which can be written as (see link for formula). In previous work, we applied a diagrammatic method to bring out the feedback features of this model in the case when all modes have equal access to the pumping source. This approach is generalized by assuming that modal pumping rates are dependent on occupation numbers according to formula (see link for formula), which expresses the idea that oscillators first must be primed in order to absorb the available energy in full extent. Results suggest marked differences in behavior of oscillators with different frequencies.
Electrodynamic Signaling by the Dendritic Cytoskeleton: Toward an Intracellular Information Processing Model
Avner Priel, Jack A. Tuszynski, Horacio F. Cantiello, Department of Physics, University of Alberta, Edmonton, Alberta, Canada as well as Massachusetts General Hospital and Harvard Medical School, Charlestown, USA -
A novel model for information processing in dendrites is proposed based on electrodynamic signaling mediated by the cytoskeleton. Our working hypothesis is that the dendritic cytoskeleton, including both microtubules (MTs) and actin filaments plays an active role in computations affecting neuronal function. These cytoskeletal elements are affected by, and in turn regulate, a key element of neuronal information processing, namely, dendritic ion channel activity. We present a molecular dynamics description of the C-
