Radiation signature on exposed cells: Relevance in dose estimation

The radiation is considered as a double edged sword, as its beneficial and detrimental effects have been demonstrated. The potential benefits are being exploited to its maximum by adopting safe handling of radionuclide stipulated by the regulatory agencies. While the occupational workers are monitored by personnel monitoring devices, for general publics, it is not a regular practice. However, it can be achieved by using biomarkers with a potential for the radiation triage and medical management. An ideal biomarker to adopt in those situations should be rapid, specific, sensitive, reproducible, and able to categorize the nature of exposure and could provide a reliable dose estimation irrespective of the time of the exposures. Since cytogenetic markers shown to have many advantages relatively than other markers, the origins of various chromosomal abnormalities induced by ionizing radiations along with dose-response curves generated in the laboratory are presented. Current status of the gold standard dicentric chromosome assay, micronucleus assay, translocation measurement by fluorescence insitu hybridization and an emerging protein marker the g-H2 AX assay are discussed with our laboratory data. With the wide choice of methods, an appropriate assay can be employed based on the net.

＜正＞Model systems play an important role in the fundamental research of colloid *** the past decades,a monodisperse rod-like virus-fd has been used as an anisotropic colloid *** virus has a length of 880 nm and a diameter of 8.8 *** to its nanorod-like nature,this virus has also been harnessed as templates for nanomaterials.1 In this *** present the synthesis and selected macroscopic properties of a new model system consisting of poly（N-isopropylacrylamide）（PNIPAM）-coated rod-like fd virus particles.2 The sticky rod-like colloids can be used to study effect of particle shape on gelation transition,the structure and viscoelasticity of isotropic and nematic gels,and to make both open isotropic as well as ordered nematic particle *** model system of rod-like colloids,for which the strength of attraction between the particles is tunable,is obtained by chemically grafting rod-like fd virus particles with thermoresponsive polymers,*** room temperature,suspensions of the resulting hybrid PNIPAM-fd are fluid sols which are in isotropic or liquid crystalline phases,depending on the particle concentration and ionic *** heating/cooling,the suspensions change reversibly between sol and gel state near a critical temperature of 32℃.close to the lower critical solution temperature of free PNIPA *** so-called nematic gel,which exhibits a cholesteric feature,can therefore be easily *** gelation behavior of PNIPAM-fd system and the structure of the nematic gel have been characterized by rheology,optical microscopy and small-angle X-ray scattering.
