Photodynamic therapy (PDT) combines a drug or photosensitizer with a specific type of light to kill cancer cells. The cellular damage induced by PDT leads to activation of the DNA damage repair, which is an important factor for modulating tumor sensitivity to this treatment. beta-Glucans are natural polysaccharides that bind complement receptor 3 on the(More)
AIM Autofluorescence of experimental tumor (hepatoma A22 (MH-A22)) was employed to discriminate the optical differences between necrotic and non-necrotic tumor, hemorrhagic tumor and healthy tissue. METHODS The experiment was performed ex vivo using the transplantable tumor from the right haunch of hybrid mice (C57Bl/CBA). Blue LED light (lambda em=405(More)
The biological effects of low-dose radiation have attracted attention, but data are currently insufficient to fully understand the beneficial role of the phenomenon. In the present study, we have investigated the effects of low doses of gamma-irradiation alone and in combination with all-trans-retinoic acid (RA) on proliferation, apoptosis and(More)
