Introduction: To enhance radiation therapy efficiency it is crucial to implement an individual-based treatment. The aim of present study was to identify the mechanism of intrinsic apoptosis pathway on radiosensitivity and normal tissue complications caused by the radiotherapy.   Materials and Methods: radiation-induced apoptosis in periphera...

This work has developed a novel approach to form common carotid artery (CCA) thrombus in rats with a wireless implantable light-emitting diode (LED) device. The device mainly consists of an external controller and an internal LED assembly. The controller was responsible for wirelessly transmitting electrical power. The internal LED assembly served as an implant to receive the power and irradiat...

Ionizing radiation is the primary nonsurgical treatment modality for solid tumors. Its effectiveness is impacted by temporal constraints such as fractionation, hypoxia, and development of radioresistant clones. Biomarkers of acute radiation response are essential to developing more effective clinical algorithms. We hypothesized that acute perturbations in tumor lactate levels act as a surrogate...

AIMS Redox homeostasis is critical in regulating the fate and function of multipotent cells in the central nervous system (CNS). Here, we investigated whether low dose charged particle irradiation could elicit oxidative stress in neural stem and precursor cells and whether radiation-induced changes in redox metabolism would coincide with cognitive impairment. RESULTS Low doses (<1 Gy) of char...

This Case Report has presented health effects of high level of irradiation with gamma rays from Ir 192m on the patient M. L. during 21 years after the accident. The main purpose of this investigation was to analyze long time consequences of partial high-level irradiation on human health. Locally, short-term irradiation, with high deadly dose, caused acute radiation syndrome with reversible diso...

A randomized trial of 12.0 Gy versus 15.75 Gy of total body irradiation (TBI) was performed in patients with acute myeloid leukemia undergoing allogeneic marrow transplantation while in first complete remission. All patients received 120 mg/kg cyclophosphamide followed by TBI and marrow from HLA-identical siblings. Cyclosporine and methotrexate were used for prophylaxis against acute graft-vers...

Bacterial translocation/Acute radiation syndrome/Endotoxin/G-CSF/OK-432 Acute radiation induces bacterial translocation from the gut, followed by systemic infection and sepsis. In order to reduce the mortality after acute whole body irradiation, it is essential to control bacterial translocation. In this study, we established a bacterial translocation assay as a sensitive method to detect minor...

AIM To evaluate the efficacy and toxicity of palliative re-irradiation for in-field recurrence of primary lung cancer after radiotherapy. PATIENTS AND METHODS Forty-four patients with locally recurrent lung cancer after radiotherapy were retreated with external beam radiation therapy. To evaluate palliative effectiveness, 31 symptoms in 25 patients were analyzed, while all patients were analy...
