It is thus recommended to take possible seasonal differences into account when using mink exposure data. The overall results suggest
that the mink is a suitable find more sentinel species for assessing and monitoring environmental levels of PFAAs. (C) 2013 The Authors. Published by Elsevier Ltd. All rights reserved.”
“Background: Despite advances in medical, surgical, and radiation oncology, deep-seated bone sarcomas that require large osseous resections continue to present resection and reconstructive challenges to musculoskeletal surgeons.
Methods: We describe our experience with computer navigation techniques combined with complex pelvic resections and limb-preserving surgeries.
Results: Computer-assisted navigation has shown promise in aiding in optimal preoperative planning and in providing more accurate and precise feedback during surgery.
Conclusions: Computer-assisted navigation offers precise instrumentation, technology-oriented imaging systems, and powerful information processing, all of which can assist in decision making, preoperative planning, and surgical accuracy.”
“Magnetometry, x-ray, and neutron scattering have been used to study the structural and magnetic properties of a TbMnO3 thin film grown on a [001] SrTiO3 substrate by pulsed laser deposition. Although bulk TbMnO3 is a low temperature antiferromagnet, www.selleckchem.com/products/Acadesine.html magnetometry measurements indicate
the presence of low temperature ferromagnetism. Depth profiling by x-ray and polarized neutron reflectometry reveals a net sample magnetization that is commensurate with the film thickness, indicating that the observed ferromagnetism is not due to an altered surface phase (such as Mn3O4), or external impurities that might give rise to an artificial magnetic signal. Instead, these results selleck kinase inhibitor show that the ferromagnetism is an intrinsic property of the TbMnO3 film. (C) 2009 American Institute of Physics. [DOI:

“Objectives: Emissions of mercury in the environment have been decreasing for several years. However, mercury species are still found in different media (food, water, air and breast-milk). Due to mercury toxicity and typical behaviour in children, we have conducted a mercury exposure assessment in French babies, and small children aged 0 to 36 months.
Method: Consumption and mercury concentration data were chosen for the exposure assessment. The Monte Carlo technique has been used to calculate the weekly exposure dose in order to integrate inter-individual variability and parameter uncertainty. Exposure values have been compared to toxicological reference values for health risk assessment.
Results: Inorganic mercury median exposure levels ranged from 0.160 to 1.649 mu g/kg of body weight per week (95th percentile (P95): 0298-2.027 mu g/kg bw/week); elemental mercury median exposure level in children was 0.
