The exposure of primary rat neocortical astroglial cell cultures to acute electromagnetic fields (EMF) in the microwave range was studied. Differentiated astroglial cell cultures at 14 days in vitro were exposed for 5, 10, or 20min to either 900MHz continuous waves or 900MHz waves modulated in amplitude at 50Hz using a sinusoidal waveform and 100%… (More)
The emission spectrum of ultraviolet A laser induced ultraweak delayed luminescence in cell cultures of mammalian cells depended on the temperature during irradiation and photonic measurements. A new method using a sophisticated photomultiplier system was developed in order to find differences between normal and tumor cells. The maximal peak of the emitted… (More)
Menadione (MD) is an effective cytotoxic drug able to produce intracellularly large amounts of superoxide anion. Quercetin (QC), a widely distributed bioflavonoid, can exert both antioxidant and pro-oxidant effects and is known to specifically inhibit cell proliferation and induce apoptosis in different cancer cell types. We have investigated the relation… (More)
This paper compares some features of the delayed luminescence in the seconds range emitted from an unicellular alga Acetabularia acetabulum and from some solid state systems. Results lead us to think that such delayed luminescence is connected to the dimension of the ordered structures present in both biological and solid state systems. In particular, for… (More)
Delayed luminescence from ox Achilles' tendons is found to depend on the order parameters of the collagen fibres and on both water content and the temperature, which affect those parameters.
The kinetics of the delayed luminescence arising from correlated coherent many-soliton states in low-dimensional macromolecular systems, is calculated and shown to be different from the one arising from independent soliton states. The correlation between coherent electron states is essential at relatively high levels of excitation in the presence of very… (More)
The effect of self irradiation on yeast cells has been investigated by counting the young gemmae formation in 104 self irradiated samples, as compared with an equal set of control samples. The results show that the rate of gemmae formation is higher in self irradiated samples; the statistical significance of the results is discussed.
In vivo measurements of Delayed Luminescence (DL), the low-level photo-induced emission which lasts for a longer time after switching off the excitation light, have been performed on human skin, with the aim to develop a technique for optical biopsy. Preliminary tests have been performed on healthy volunteers, measuring the time decays of the spectral… (More)
Photoinduced ultraweak photon emission in the seconds time range from several living organisms is described. Some characteristics of this phenomenon and its dependence on some physical parameters are discussed. Some experimental evidence of the connection between this phenomenon and the functional state of the biological systems is reported.
Time resolved spectral components of delayed luminescence (DL) from single dry soybean seeds were measured using a device with single photon sensitivity. The seeds were aged by a thermal treatment to change their viability. A correlation was observed between the seeds viability and some DL parameters, i.e. the total number of photons emitted and the… (More)
