Reactive oxygen species formed as a response to various abiotic and biotic stresses cause an oxidative damage of cellular component such are lipids, proteins and nucleic acids. Lipid peroxidation is considered as one of the major processes responsible for the oxidative damage of the polyunsaturated fatty acid in the cell membranes. Various methods such as a loss of polyunsaturated fatty acids, ...

all biological samples emit ultra-low intensity light without any external stimulation. recently, scientific communities have paid particular attention to this phenomenon, known as ultra-weak photon emission (upe). upe has been introduced in the literature as an alternative for biophoton, low-level chemiluminescence and ultra-weak bioluminescence, while it differs from ordinary bioluminescence,...

Two-dimensional imaging of spontaneous ultra-weak photon emission was measured in the yeast cells, Arabidopsis plant and the human hand using highly sensitive charge coupled device (CCD) camera. For the first time, the detail analysis of measuring parameters such as accumulation time and binning is provided with the aim to achieve two-dimensional images of spontaneous ultra-weak photon emission...

Ultra-weak photon emission (UPE) of a living system received scientific attention because of its potential for monitoring increased levels of reactive oxygen species (ROS) in the pathogenesis of rheumatoid arthritis (RA). In this study, a highly sensitive cryogenic charge-coupled device (CCD) camera was used to monitor in a RA mouse model the photon emission both without and with luminol. For t...

Ultra-weak photon emission of a living system has received scientific attention because of its potential for monitoring oxidative metabolism and oxidative damage to tissues. Heretofore, most studies have focused only on the emission from hands. The data regarding emission from other anatomic locations are limited. A previous multi-anatomic site recording of four subjects quantitatively demonstr...

objective: it is well-known that all living cells emit ultra-weak photon emission (upe), which is due to byproducts of chemical reactions in cell metabolisms. it has been shown that reactive oxygen species (ros) in the cells enhances the upe intensity. the magnitude of such upe is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...

During the past 20 years, the connective tissue has been recognized as an integral component of the Chinese acupuncture meridian system. This has offered an interesting correspondence between the classical Chinese theory and a 200 year-old European theory on connective tissue as basic bioregulatory system. We review supporting evidence from biochemistry, cell biology, biophysics and biophotonic...
