At least one massive binary system containing an energetic pulsar, PSR B125963/SS2883, has been recently detected in the TeV γ-rays by the HESS telescopes. These γ-rays are likely produced by particles accelerated in the vicinity of the pulsar and/or at the pulsar wind shock, in comptonization of soft radiation from the massive star. However, the process of γ-ray production in such systems can ...

PURPOSE Microbial contamination of different cosmetic preparations, as a result of preservative failure, presents a major public health threat. Also, most of the known preservatives have serious consumer side effects. The antimicrobial activity of zinc oxide nanoparticles (ZnO NP) is well documented. Therefore, we aimed to determine the possible use of unirradiated and γ-irradiated ZnO NP as a ...

Shanghai Laser Electron Gamma Source, a γ-ray beam line of 10MeV order was proposed recently. The beam line is expected to generate γ-ray with maximum energy of 22MeV by backward Compton scattering between CO2 laser and electron in the 3.5GeV storage ring of future Shanghai Synchrotron Radiation Facility. The flux of non-collimated γ-ray can be 10 ∼ 10 s if a commercial CO2 laser of 100W order ...

Ionizing radiation has been shown to produce negative effects on organisms, although little is known about its ecological and evolutionary effects. As a study model, we isolated bacteria associated with feathers from barn swallows Hirundo rustica from three study areas around Chernobyl differing in background ionizing radiation levels and one control study site in Denmark. Each bacterial commun...

PURPOSE To investigate effects of neuro-immuno-modulation on wound healing by observing changes of cytokines and hypothalamic-pituitary-adrenal (HPA) axis hormones in acute stress reaction in rats with wound and combined local radiation injury. METHODS Sixty female Wistar rats (weighting 200 ± 20 g) were randomly divided into normal control group, wound group and combined wound-local radiatio...

Previous studies have suggested that microwave (MW) radiation with certain parameters can induce spatial memory deficits. However, the effect of MW on topological organization brain network is still unknown. This work aimed to investigate in rats impairments induced by acute radiation. The Morris water maze (MWM) test and resting-state functional magnetic resonance imaging were performed estima...

Hydroferrate fluid, MRN-100, an iron-based compound derived from bivalent and trivalent ferrates, is a potent antioxidant compound. Therefore, we examined the protective effect of MRN-100 against γ-radiation-induced lethality and damage to hematopoietic tissues in fish. A total of 216 Nile tilapia fish (Oreochromis niloticus) were randomly divided into four groups. Group 1 served as a control t...
