The aim of this study was to examine the early effects of low dose (12)C(6+) irradiation or X-ray on peripheral blood lymphocytes (PBL) of patients with alimentary tract cancer and to explore mechanisms that may be involved in an antitumor immune response. We found that the percentage of T lymphocyte subsets, the mRNA expression levels of IL-2 and IFN-γ in PBL, and their protein levels in super...

Although safe doses of radiation have been determined, concerns about the harmful effects of low-dose radiation persist. In particular, to date, few studies have investigated the correlation between low-dose radiation and disease development. Asthma is a common chronic inflammatory airway disease that is recognized as a major public health problem. In this study, we evaluated the effects of low...

Background: Breast cancer is becoming more frequently diagnosed at early stages with improved long term outcomes. Radiation-related heart disease and lung cancer can occur following radiotherapy for breast cancer. The aim of this study was to evaluate some dosimetric parameters of heart and lung during whole breast radiotherapy. Methods:Twenty five consecutive...

OBJECTIVE Low-dose whole-body irradiation is known to have anti-inflammatory effects. The objectives of this study were to verify that cytokine augmentation is induced by irradiation in vivo, and to assess the effectiveness of radiation in treating Behçet's disease (BD). METHODS Whole-body and half-body irradiation with single doses of 10cGy, 2Gy and 10Gy were delivered to normal mice, and cy...

Introduction: Breast cancer is becoming more frequently diagnosed at early stages with improved long-term outcomes. Radiation-related heart disease and lung cancer can occur following radiotherapy for breast cancer. The aim of this study was to evaluate some dosimetric parameters of heart and lung during whole breast radiotherapy. Materials and Methods: Twenty...

To investigate the irradiation properties of Mo-Re alloy of low Re content (atm%: 0% 8:4%), Mo-Re alloy films were irradiated by 200 keV xenon ions at the dose of 5 10 ions/cm. Different irradiation effects were observed on the samples of different Re content. While the sample of pure Mo remained the same after irradiation, obvious localized amorphization phenomenon took place in the sample wit...

Due to low neutron absorption cross section, high mechanical strength, thermal conductivity and good corrosion resistance in water steam, Zirconium alloys are widely used as fuel cladding material nuclear reactors. During life-time of a reactor the microstructure this alloy is affected due to, among other factors, radiation damage hydrogen damage. In work properties changes on irradiated Zr-1wt...

A sex-linked recessive lethal mutation assay was performed in Drosophila melanogaster using immature spermatocytes and spermatogonia irradiated with X rays at a high or low dose rate. The mutation frequency in the sperm irradiated with a low dose at a low dose rate was significantly lower than that in the sham-irradiated group, whereas irradiation with a high dose resulted in a significant incr...

INTRODUCTION The problem of correct estimation of low-level exposure chronic irradiation biological consequences is one of the most important unsolved problem. It is actual for radiobiology and radioecology at the moment. The development of new concept of radiation protection of human and biota should be based on clear understanding of low-level chronic exposure biological consequences. The est...
