A model of an enzyme reaction cycle that includes the generation of a transient spin-correlated radical pair state is discussed. The recombination yield of the radical pair state is altered by external magnetic fields (radical pair mechanism). In thi

A model of two relaxation-type nonlinear oscillators is investigated. The chaotic spike sequence generated by the first system is used as a subthreshold input signal for the second system. When also exposed to noise, the latter behaves as a detector

The question of how electromagnetic fields - static or low to high frequency - interact with biological systems is of great interest. The current discussion among biologists, chemists, and physicists emphasizes aspects of experimental verification an

Although there is evidence that changes in cellular ionic concentrations are important early events in apoptosis, the regulation of ion fluxes across the plasma membrane during this process is poorly understood. We report here that Bcl-2 overexpressi

The influence of gamma radiation on basal compared to activation-dependent Ca(2+) influx in human lymphocytes was investigated. A new quantitative fluorescence technique termed differential ratiometric fluorescence spectroscopy (DRFS) was employed. D

It is widely accepted that moderate levels of nonionizing electric or magnetic fields, for example 50/60 Hz magnetic fields of about 1 mT, are not mutagenic. However, it is not known whether such fields can enhance the action of known mutagens. To ex

The feasibility of magnetic field perturbations as a tool for controlling enzyme-regulated and oscillatory biochemical reactions is studied. Our approach is based on recent experimental results that revealed magnetic field effects on the in vitro act
