Biological basis for radiation hormesis in mammalian cellular communities
It is now known that low doses and dose rates of certain agents (e.g., radiation and genotoxic chemicals) can induce protective processes that together lead to a reduction in mutations and neoplastic transformation below the spontaneous frequency in mammalian in vitro and in vivo cellular communities. However, after high doses, some of the protection is lost, leading to elevated risks relative to ...

Low doses of amifostine protect from chromosomal inversions in spleen in vivo when administered after an occupationally relevant X-radiation dose
Amifostine is a chemical radioprotector known to protect cells from DNA damage and toxicity normally induced by high-dose radiation exposure. Here, we used the sensitive in vivo pKZ1 mouse chromosomal inversion assay to determine the radioprotective effect of different doses of amifostine in the presence and absence of 250 mGy whole-body X-irradiation, the present radiation dose limit for ...

Estimating population‐level HC5 for copper using a species sensitivity distribution approach
Estimation of population‐level benchmark concentrations for protecting aquatic organisms from chemicals is important for value‐relevant ecological risk assessments. Here, by employing a species sensitivity distribution (SSD) approach, we aimed to derive the population‐level hazardous concentration for 5% of species (PHC5) for copper. Based on available information on copper toxicity and ...

The challenge of predicting problematic chemicals using a decision analysis tool: Triclosan as a case study
Manufacturers lack a reliable means for determining whether a chemical will be targeted for deselection from their supply chain. In this analysis, three methods for determining whether a specific chemical (triclosan) would meet the criteria necessary for being targeted for deselection are presented. The methods included a list‐based approach, use of a commercially available chemical assessment ...

Synthesis and characterisation of nano silica-based coatings for protection of antique articles
Antique articles are endangered by environmental effects such as humidity, UV and variation of temperature. Improved physical surface resistance is in an increasing demand in protection of cultural heritage. One possible way is their protection by suitable hydrophobic coatings. In this work, the experimentation of protective treatments on the soda glass, mud brick and copper, characteristic ...
