Introduction :Today there is general awareness of the potential damage to the heart in left- sided (more than in rightsided) breast cancer radiotherapy.     Material & Method: Historical changes in tumor and heart doses are presented here along with the impact of different RT techniques and volumes. Results: Individual and pharm...

In recent decades many researchers have studied on the damage assessment of structures after a seismic event. To assess the damage of structures under an earthquake, it is so important to study the correlations between earthquake parameters and damages of the structures. A lot of seismic parameters have been defined by researchers to characterize an earthquake. Spectral parameters of an earthqu...

With no routine accessible medicine intervention for spinal cord damage, there is a demand for more remedial candidates. However, for Imatinib to have translational price, it requires to have encouraged obliging effects with delayed start of treatment, as well. Serum levels of 3 chemokines/ cytokines, MIP-3α, MCP-1, and GRO/ KC (IL-8), to raise over time with Imatinib treatment and to be ...

Background: DNA damage is one of the major consequences of radiation exposure onto the biological systems. A series of compounds including flavanoids were found to render DNA protection against radiation damage. In this study we elucidated the potential of rutin and rutin hydrate to protect plasmid DNA against damage induced by irradiation. Materials and Methods: DPPH and hydroxyl radical scave...

Background: Naringenin is a bioactive flavonoid found in grapes and citrus fruits including tangelo, blood orange, lemons, and tangerines. The aims of this study were to investigate the ability of naringenin to scavenge free radicals and determine its ability to protect animals from streptozotocin (STZ) -induced liver damage. Methods: The free radical-scavenging activity of naringenin was ev...

6- mercaptopurine (6-mp) is widely used in clinic as an immunosuppressive for treatment of acute lymphocytic leukemia, crohn's disease, and ulcerative colitis with documented unpredictable hepatotoxicity. the potential molecular cytotoxic mechanisms of 6-mp against isolated rat hepatocytes were searched in this study using “accelerated cytotoxicity mechanism screening (acms)” techniques. t...

chloroacetaldehyde (caa) is a chlorination by-product in finished drinking water and a toxic metabolite of a wide variety of industrial chemicals (e.g. vinyl chloride) and chemotherapeutic agents (e.g. cyclophosphamide and ifosfamide). in this research, the cytotoxic mechanisms of caa in freshly isolated rat hepatocytes were investigated.caa cytotoxicity was associated with reactive oxygen spec...
