Sensitivity of Staphylococcus aureus Strains to Broadband Visible Light
The phototoxic effect of illumination with broadband visible light on the viability of two Staphylococcus aureus strains was examined in the present study. A difference in the light sensitivity ofExpand
Effects of visible and near-infrared lasers on cell cultures.
The effect of 360, 632 and 780 nm light on NIH fibroblast cells was examined. Mitosis counts of irradiated cells at various energy doses were taken. Scanning electron micrographs of these cells wereExpand
Red light-induced redox reactions in cells observed with TEMPO.
OBJECTIVE The aim of this study was to determine the wavelength dependence of light-induced redox reactions in cells, particularly whether there is any contribution by red wavelengths. An additionalExpand
EPR Study of Visible Light-Induced ROS Generation by Nanoparticles of ZnO
Nanoparticles of ZnO have been shown to have marked antibacterial and anticancerous activities. The toxic effect of ZnO has been found to exist due to a reaction of the ZnO surface with water. In theExpand
Photochemistry and photobiology of light absorption by living cells.
In this review, we summarize a part of our research concerning photobiostimulative effects on cardiomyocytes, sperm cells, and nerve cells. We concentrate on results demonstrating thatExpand
A possible mechanism for the bactericidal effect of visible light.
Visible light at high intensity was found to kill bacteria while low-power light in the visible and near infrared region enhances bacterial proliferation. The present review summarizes evidenceExpand
Low Energy Visible Light Induces Reactive Oxygen Species Generation and Stimulates an Increase of Intracellular Calcium Concentration in Cardiac Cells*
Low energy visible light (LEVL) irradiation has been shown to exert some beneficial effects on various cell cultures. For example, it increases the fertilizing capability of sperm cells, promotesExpand
The healing effect of low energy lasers is generally attributed to enhanced cell proliferation due to the irradiation. As it was not clear whether coherent irradiation is essential, we examined theExpand
Changes in calcium transport in mammalian sperm mitochondria and plasma membrane irradiated at 633 nm (HeNe laser).
The effect of light on calcium transport in mammalian sperm mitochondria and plasma membrane was studied. Digitonine-treated spermatozoa and plasma membrane vesicles were irradiated with an HeNeExpand
Effect of light on calcium transport in bull sperm cells.
The effect of light on calcium transport was studied. Bull sperm cells were irradiated with an He-Ne (630 mm) laser and a 780 nm diode laser at various energy doses, and 45Ca2+ uptake was measured byExpand
