Nonetheless, there was no significant difference between this treatment group and 1 mM melatonin group. Moreover, the administration of melatonin in combination with irradiation did not show any significant effects on radiation-induced apoptosis. The current study results indicated that the treatment of A549 cells with melatonin could suppress cell proliferation, whereas it did not mediate the induction of apoptosis.

Melanoma causes the highest number of skin cancer-related deaths worldwide. New treatment methods are essential for the management of this life-threatening disease. In this study, we investigated the efficacy of a standardized Cannabis sativa extract alone or in combination with single radiation dose (6 Gy) in B16F10 mouse melanoma cells in an extract dose-dependent manner. C. sativa extract at three concentrations (25, 12.5, and 6.25 μg/mL) alone for 72 h or in combination with radiation (24 h incubation after the extract treatment + 48 h incubation after exposure to radiation) were evaluated for cell viability of melanoma cells using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Cells were also treated with 6.25 μg/mL extract alone for 72 h before analyzing C. sativa-induced cell death by flow cytometry. Administration of the extract alone or alongside radiation substantially inhibited melanoma cell viability and proliferation in the extract dose response-dependent manner. The anoma. T1-contrast and T2-flair images of magnetic resonance imaging (MRI) are commonly fused with computed tomography (CT) and used for delineation of postoperative residual tumor and bed after surgery in pat
