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...

There have been few reports regarding the metabolic effects of X-ray irradiation on adult human articular chondrocytes. The purpose of this study was to evaluate whether exposure to X-ray irradiation during tumor surgery can cause impaired metabolism in adult articular cartilage. To achieve this we exposed cultured chondrocytes isolated from normal or degenerated cartilage to varying doses of X...

Edaravone, a clinical drug used widely for the treatment of acute cerebral infarction, is reported to scavenge free radicals. In the present study, we investigated the radioprotective effect of edaravone on X-ray-induced apoptosis in MOLT-4 cells. Apoptosis was determined by the dye exclusion test, Annexin V binding assay, cleavage of caspase, and DNA fragmentation. We found that edaravone sign...

The effects of irradiation with 17 MeV electron beams and “‘Co y-rays on the magnetic flux of Nd-Fe-B and Sm-Co permanent magnets have been studied. At an electron dose of 2.1 X 10d3 C/cm’ (at an absorbed dose of 2.6 MGy), the magnetic flux loss of Nd-Fe-B is 9%, while the flux loss of Sm-Co is below 0.4% at a dose of 1.4 X 10B3 C/cm’. After remagnetization of the irradiated Nd-Fe-B sample the ...

Six groups of 3 rabbits each were immunised with ovalbumin and received one intra-articular injection of antigen. The animals of 3 groups received local x-ray irradiation of 600 rads for 8 minutes to the right knee joint 12 days after the intra-articular challenge. Animals of the other 3 groups were not irradiated. The antigen-induced arthritis was investigated by determining the exudation is s...

The photocatalytic degradation of Acid Red 91 (AR91) and Acid Yellow 23 (AY23) with different molecular structures and different substitute groups using Pt modified TiO2 (PtTiO2 ) nanoparticles was investigated in the presence of visible light irradiation. Pt-TiO2 nanoparticles were prepared with photodiposition method (PD) and characterized by X-ray diffraction (XRD), scanning electron microgr...

In this study, Nitrogen doped TiO2 photocatalysts were prepared by the sol gel method and physicochemical properties were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), photoluminescence, and energy dispersive X-ray spectroscopy (DRS) techniques. The XRD data indicated that the nanoparticles had the same crystals structures as the pure TiO2</su...

We have examined mutations in the supF gene carried by pTN89 plasmids in Escherichia coli (E. coli) to examine the effects of extremely low frequency magnetic fields (ELFMFs) and/or X-rays to the plasmids. The plasmids were subjected to sham exposure or exposed to an ELFMF (5 mT), with or without X-ray irradiation (10 Gy). For the combined treatments, exposure to the ELFMF was immediately befor...

Nanocrystals of ZnO were prepared by microwave irradiation using Zn (II) acetate and triethanol amin (TEA) as the starting materials and water as solvent. The nanocrystals of ZnO with hexagonal (Wurtzite) structure were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), UV-Vis absorption and FTIR Spectroscopy techniques.

the results of researches in the field of the using x-ray in all over the world have been successful. the main subject which needs more investigation and have been allocated part of the researches in most of the atomic research institutes, is the research about possible harms of irradiated food for human beings, base on the researches, using irradiation for inhibition of sprouting and preservat...
