Resumen

Radiation of different wavelengths can kill living organisms, although, the mechanism of interactions differs depending on their energies. Understanding the interaction of radiation with living cells is important to assess their harmful effects and also to identify their therapeutic potential. Temporally, this interaction can be broadly divided in three stages – physical, chemical and biological. While radiation can affect all the important macromolecules of the cells, particularly important is the damage to its genetic material, the DNA. The consequences of irradiation include- DNA damage, mu

Resumen

Ionizing radiation (IR) is considered a traditional mutagen and genotoxic agent. Exposure to IR affects in all cases biological systems and living organisms from plants to humans mostly in a pernicious way. At low (<0.1 Gy) and low-to-medium doses (0.1–1 Gy), one can find in the literature a variety of findings indicating sometimes a positive-like anti-inflammatory effect or detrimental-like toxicity. In this Special Issue and in general in the current research, we would like to acquire works and more knowledge on the role(s) of DNA damage and its repair induced by ionizing radiations as in

Resumen

The effect of Anderson localization in DNA on the Auger destruction by the Coulombic explosion at ionized radiation has been theoretically discussed in the present work. The theory of Auger destruction of DNA has been modified taking into account the localized and delocalized electron states in DNA owing to the correlated disorder in a sequence of nucleotides. According to the modified theoretical model of Auger destruction, the dominant ratio of delocalized states to localized states in exon compared to intron results in stronger radiation resistance of exons to ionized irradiation causing th

Resumen

The effect of the anticancer drug cisplatin (alone and in combination with γ-radiation) on the initiation of DNA synthesis in Friend leukemia cells was studied. A method for isolation of DNA fractions containing the origins of replication was used. It was found that cisplatin decreased the rate of the initiation of DNA synthesis. The mild γ-radiation has previously been observed to inhibit the initiation of DNA synthesis. In the present investigation the combination of cisplatin and γ-radiation showed additive effects without synergism on the initiation of DNA biosynthesis.

Stability of the DNA molecule is essential for the proper functioning and sustainability of all living organisms. In this study, we investigate the effect of gamma radiation (γ-radiation) on spin-selective electron transfer through double strand (ds)DNA molecules. Self-assembled monolayers (SAMs) of 21-base long DNA are prepared on Au-coated Ni thin film. We measure the spin polarization (%) of the SAMs of ds-DNA using the spin-dependent electrochemical technique. We use a Cs-based γ-radiation source to expose the SAMs of ds-DNA immobilized on thin films for various time intervals ranging from

Resumen

One of the negative effects of ionizing radiation is the alteration of cellular signaling pathways which lead to carcinogenesis and tumorigenesis. In this review, we discussed the impacts of ionizing radiation on cells and cellular signaling pathways. In this regard, exposure to radiation can directly or indirectly alter cellular signaling pathways. Remarkably, irradiated cells release special mediators into cellular matrix, aberrating cell-cell and cell-environment interactions. Most notably, these mediators include nitric oxide (NO), reactive oxygen species (ROS), and cell growth factors whi

Resumen

Abstract Plasmid DNA is commonly used as a simpler substitute for a cell in studies of early effects of ionizing radiation because it allows to determine yields of primary DNA lesions. Experimental studies often employ plasmids of different lengths, in different concentrations in the aqueous solution. Influence of these parameters on the heavy-ion induced yields of primary DNA damage has been studied, using plasmids pUC19 (2686 bp), pBR322 (4361 bp) and pKLAC2 (9107 bp) in 10 and 50 ng/μl concentration. Results demonstrate the impact of plasmid length, while no significant difference was obser

Resumen

Ionizing radiation (IR) causes damage to DNA that is apparently proportional to absorbed dose. The incidence of radiation-induced cancer in humans unequivocally rises with the value of absorbed doses above about 300 mGy, in a seemingly linear fashion. Extrapolation of this linear correlation down to zero-dose constitutes the linear-no-threshold (LNT) hypothesis of radiation-induced cancer incidence. The corresponding dose-risk correlation, however, is questionable at doses lower than 300 mGy. Non-radiation induced DNA damage and, in consequence, oncogenic transformation in non-irradiated cells

Background: Heavy ion radiation has more advantages than traditional radiation therapy in the treatment of cancer, mainly because of its superior biological effects. However, there is currently no reliable evidence that heavy ion radiation can induce cell death in hydatid cysts at the cellular and molecular level. In addition, we believe heavy ion therapy could be a potential alternative approach for the treatment of hydatid cysts.

Time of flight laser photoionization has been used to study the response of some molecules of biological interest under laser radiation. One of the questions of great interest today is the effect of radiation on DNA and RNA molecules. Damage to these molecules can be caused directly by radiation or indirectly by secondary electrons created by radiation. As response of the radiation field fragmentation process can occur producing different ions with kinetic energies of a few electron volts.

SynopsisThis paper presents a chemist's view of the action of ionising radiation on matter with a range of simple examples. Attention is given to the ways in which electron spin resonance spectroscopy (which is described briefly) can be harnessed to give useful information about the initial stages of radiation damage. The effects of radiation are generally indiscriminate and hence damage to water is of special importance in biological systems. Water-derived free radicals will attack biomolecules (the indirect effect) and this mechanism is compared with direct damage events. Also, examples are

Resumen

Radiation therapy (RT) in some cases results in a systemic anticancer response known as the abscopal effect. Multiple hypotheses support the role of immune activation initiated by RT-induced DNA damage. Optimal radiation dose is necessary to promote the cGAS-STING pathway in response to radiation and initiate an IFN-1 signaling cascade that promotes the maturation and migration of dendritic cells to facilitate antigen presentation and stimulation of cytotoxic T cells. T cells then exert a targeted response throughout the body at areas not subjected to RT. These effects are further augmented th

Resumen

The effect of -radiation on the level of nuclear DNA damage in onion seedlings (Allium-test) was studied using the comet assay. DNA breaks were first found in cells of onion seedlings exposed to low-dose radiation ( 0,1 Gy). Dose dependence of DNA damage parameters showed nonlinear behavior: a linear section in the low-dose region (below 0,1 Gy) and a dose-independent plateau in the dose range between 1 and 5 Gy. Thus, the comet assay can be used to estimate the biological effects of low-dose gamma-radiation on Allium cepa seedlings.

Although ionizing radiation (radiation) is commonly used for medical diagnosis and cancer treatment, radiation-induced damages cannot be avoided. Such damages can be classified into direct and indirect damages, caused by the direct absorption of radiation energy into DNA and by free radicals, such as hydroxyl radicals (•OH), generated in the process of water radiolysis. More specifically, radiation damage concerns not only direct damages to DNA, but also secondary damages to non-DNA targets, because low-dose radiation damage is mainly caused by these indirect effects.

By definition, low doses are minimum doses of a damaging agent, in particular radiation, causing a recorded biological effect. The problem of exposure to low doses of radiation is being discussed in scientific literature for decades, but there is still no generally accepted conclusion concerning the existence of some features of the effect of low doses in contrast to that of acute exposure. This is due to the fact as follows: if being fixed, these effects have a weak expression and can be easily criticized.

Resumen

Administration of exogenous keratinocyte growth factor (KGF) prevents or attenuates several forms of oxidant-mediated lung injury. Because DNA damage in epithelial cells is a component of radiation pneumotoxicity, we determined whether KGF ameliorated DNA strand breaks in irradiated A549 cells. Cells were exposed to 137Cs gamma rays, and DNA damage was measured by alkaline unwinding and ethidium bromide fluorescence after a 30-min recovery period. Radiation induced a dose-dependent increase in DNA strand breaks. The percentage of double-stranded DNA after exposure to 30 Gy increased from 44.6

Resumen

In the present study, we investigated the protective effect of anthocyanin extract from Lonicera caerulea var. edulis (LCA) on UVC-induced lipid and protein peroxidation using lecithin and Bull Serum Albumin (BSA) in vitro model. We also investigated the protective effect of anthocyanin on UVC induced cell injury in Spleen lymphocytes of mouse via MTT and comet assays. Peroxidation of lecithin and BSA generated by exposure to UVC radiation was significantly decreased by addition with various concentrations of LCA. Moreover, LCA exhibited an inhibitory effect on DNA damage induced by UVC radiat

Resumen

UV light has strongly influenced on the growth of E. coli as well as caused DNA damages. Configurations of both genomic DNA and pUC 19 plasmids extracted from E. coli were significantly changed by the exposure to UV light of 254 nm and DLT, an extract of Ganoderma lucidum Lingzi mushroom. The results also revealed the radio-protective effects of DLT to UV radiation. By adding 2% DLT to its culturing suspension, the growth of E. coli was significantly decreased, whereas a low DLT amount of about 0.5% slightly improved its growth, indicated that the DLT extract can be used as a promising protect

e13533 Background: It is known that some phenothiazines group of drugs have the potential to modulate ionizing radiation (IR) induced cellular damage. In our previous study, we have shown that Trifluoperazine (TFP), a phenothiazine derivative antipsychotic drug, modulate the effect of IR by inhibiting the IR induced DNA double strand break (DSB) repair, and raising the possibility of using TFP as an adjuvant to radiotherapy. In the present study we tried to explore the mechanism of IR induced DNA damage repair inhibition by TFP. Methods: Effect of TFP and IR on cell viability was determined by

Resumen

AbstractIonizing radiation which results in the free radical formation and it leads to damage of biological macromolecules such as DNA, proteins, lipids. 36 male Swiss albino mice were used for survival assay, to find out the lethal dose of Electron Beam Radiation. It was found to be 10Gy was the lethal dose for mice. Different dosages (4Gy, 6Gy and 8Gy) of electron beam radiation were used to study the micronucleus formation in irradiated mice. The results showed micronucleus formation will increase linearly with radiation dosage.
