Role of low level laser in ameliorating the damaging effects of gamma irradiation on mice liver
Background: Exposure to ionizing radiation is inevitable. Using of low-level laser therapy (LLLT) stimulates tissue repair and reduces inflammation. The objective of the present study aimed at evaluating the therapeutic efficacy of Helium-Neon (He-Ne) laser in stimulating the reparative processes in the liver of mice after whole body gamma-irradiation (WBγ-I). Materials and Methods: Two hundred...
متن کاملOver-expression of CXCR4, a stemness enhancer, in human blastocysts by low level laser irradiation
The key role of chemokine receptor CXCR4 in the maintenance of stemness property of stem cells has been shown recently. The low level laser irradiation (LLLI) is being used currently in a wide variety of clinical cases as a therapeutic tool for wound healing, relieving pain and destroying tumor cells. The aim of this study was to evaluate the effect of LLLI mimicking low level laser therapy (LL...
متن کاملEffect of low-level laser irradiation on osteoblast-like cells cultured on porous hydroxyapatite scaffolds.
OBJECTIVE To determine the effect of laser irradiation at a low dose on human osteoblastlike cells. MATERIALS AND METHODS 32 porous hydroxyapatite scaffolds currently used for bone tissue engineering were seeded with MG63 cells and irradiated or not with a GaAlAs diode laser (wavelength 915 nm, dose 2 J/cm2) using different power density and exposure duration. RESULTS After 72-h incubation,...
متن کاملLow-level laser irradiation induces in vitro proliferation of mesenchymal stem cells
OBJECTIVE To evaluate the effect of low-level laser irradiation on the proliferation and possible nuclear morphological changes of mouse mesenchymal stem cells. METHODS Mesenchymal stem cells derived from bone marrow and adipose tissue were submitted to two applications (T0 and T48 hours) of low-level laser irradiation (660 nm; doses of 0.5 and 1.0 J/cm2). The trypan blue assay was used to ev...
