Realistic dosimetry for studies on biological responses to X-rays and γ-rays
A calibration coefficient R (= DA/DE) for photons was employed to characterize the photon dose in radiobiological experiments, where DA was the actual dose delivered to cells and DE was the dose recorded by an ionization chamber. R was determined using the Monte Carlo N-Particle version 5 (MCNP-5) code. Photons with (i) discrete energies, and (ii) continuous-energy distributions under different...
متن کاملCardiovascular Changes in Atherosclerotic ApoE-Deficient Mice Exposed to Co60 (γ) Radiation
BACKGROUND There is evidence for a role of ionizing radiation in cardiovascular diseases. The goal of this work was to identify changes in oxidative and nitrative stress pathways and the status of the endothelinergic system during progression of atherosclerosis in ApoE-deficient mice after single and repeated exposure to ionizing radiation. METHODS AND RESULTS B6.129P2-ApoE tmlUnc mice on a l...
متن کاملDiffuse γ-rays from galactic halos
The γ-ray sky as we know it today is a composite of the emission from point sources and diffuse emission (see Fig.1). The most prominent feature is the galactic plane, in which interactions between cosmic rays and the thermal gas lead to γ-ray emission by π-decay and bremsstrahlung. On top of this diffuse emission we see point sources all over the map, part of them being pulsars, another part d...
متن کاملFoodborne botulinum type E intoxication associated with dried bean curd: first case report in Taiwan.
PURPOSE Botulism type E intoxication is a rare condition among human botulism. We aim to describe a first case of botulism type E intoxication in Taiwan. CASE REPORT We report a 36-year-old young man with foodborne botulism type E associated with commercially vacuum packaged dried bean curd. He developed bilateral ptosis, diplopia and dysphagia 4 days after taking the dried bean curd. Electro...
متن کاملCytogenetic and biochemical competency of chamomile essential oil against γ-rays induced mutagenic effects in mice
Background: Chamomile essential oil (CEO) hauls out from Matricaria chamomilla L., is a well-known anti-oxidant. Oxidative stress induces clastogenic and biochemical disorders after γ-irradiation of animals. Materials and Methods: Mice were divided into five groups. Control group received vehicle only. &nbs...
