• Ion-irradiated ThO 2 is not uniform with respect to Raman spectroscopy, thus many points are analyzed assess the damage. profiling of damage depth agrees quite well simulation predictions. Nuclear reactor conditions can be emulated in part by exposing potential fuel materials, such as , ion beam radiation. Changes properties then provide invaluable insight into how material will perform a fue...

Systematic Monte Carlo simulation studies have been carried out to search for a possible optimal experimental condition on the irradiation damage profile production with a given mask structure. The results suggest that minimum ion scattering broadening tails could be achieved with projectile ranges in Nb mask about half of the mask thickness. Provided the projectile range to mask thickness is m...

-We have considerably improved the properties of our electron beam damage junctions by using a smaller condenser aperture. The better defined beam results in a more concentrated damage profile. Consequently, the junctions have a more resistive barrier and higher current density compared to junctions fabricated with a large aperture. We can now obtain an IcRn value of 2 mV up to a temperature of...

We report alkaline elution experiments that reveal the temperature dependence of DNA lesions, both single-strand breaks and DNA-protein cross-links, in L1210 cells exposed to Adriamycin. DNA damage, which at 37 degrees C is equivalent to several hundred rads of ionizing radiation exposure, diminishes as the temperature of drug exposure is lowered. At all temperatures below about 15 degrees C no...

Article history: Received on: 14/07/2016 Revised on: 17/08/2016 Accepted on: 02/09/2016 Available online: 28/12/2016 Background/Aim: The liver is continuously linked to the gut via the portal vein supply. Gastrointestinal complications are directly associated with liver cirrhosis. Carbon tetrachloride (CCl4) caused liver toxicity is well documented in animal models, the very fewer search has be...

To illustrate the different kinetics of cellular self-repair mechanism under external perturbations from outer environment, a mathematical model of DNA damage repair process is proposed by using the Kinetic Theory of Active Particles (KTAP) framework. The profile of cellular self-repair process is represented by two sub-populations, each of which is made up of the active particles with differen...

Extracts were obtained from molasses, a byproduct of the sugar industry, via a number of chromatographic steps. Their antioxidant capacity was studied, including the inhibitory effect upon DNA oxidative damage; the phenolic compound profile thereof was ascertained as well. Two extracts exhibited significant antioxidant features, expressed by their capacity to decolorize ABTS radical cation and ...

Mammalian cells incur DNA damage and alterations as a result of internal factors, such as stress, environment, oxidation and metabolism, as well as exposure to external stimuli, such as chemical compounds, UV and cosmic radiation. Genotoxicity studies aim to identify and understand the mechanisms of DNA damage and repair, and also to seek methods of pathway regulation and dysregulation for impr...

High quality single Josephson junctions and junction arrays with 10 junctions in series have been fabricated using masked proton beam irradiation damage technology. Monte Carlo simulation of the irradiation damage profile underneath the metal mask has been carried out systematically to guide the metal mask structure design. A high resolution and high aspect ratio metal mask opening was fabricat...

We report alkaline elution experiments that reveal the temperature dependence of DNA lesions, both single-strand breaks and DNA-protein cross-links, in 1,121(1cells exposed to Adriamycin. DNA damage, which at 37°Cis equivalent to several hundred rads of ionizing radiation exposure, diminishes as the temperature of drug exposure is lowered. At all temperatures below about IST no DNA damage is d...
