Boron neutron capture therapy (BNCT) is a biochemically targeted radiotherapy based on the nuclear capture and fission reactions that occur when non-radioactive boron-10, which is a constituent of natural elemental boron, is irradiated with low energy thermal neutrons to yield high linear energy transfer alpha particles and recoiling lithium-7 nuclei. Clinical interest in BNCT has focused prima...

W ithin the past few decades, the water quality in many of the coastal aquifers along the Mediterranean Sea has rapidly degraded. Overexploitation of the groundwater basins, particularly during the tourist season, has resulted in the lowering of groundwater tables and increasing seawater intrusion into the aquifers. Countries such as Cyprus and Israel have shut down hundreds of wells along the ...

New alternative wood preservatives contain higher levels of copper (Cu) which can promote aquatic toxicity in natural water systems. Earlier work focused on evaluating toxicity using laboratory generated leaching solutions. In this study, the impact on preservative leaching and aquatic toxicity from treated wood products was evaluated using natural surface waters including waters from two river...

Boron (B) is an essential plant micronutrient which can be phytotoxic to plants when present in soils in high concentrations. However, despite its agronomic importance, B toxicity is poorly understood. In the present work, we study the response of the biosynthesis of cysteine and glutathione concentration under conditions B toxicity (500 mM H3BO3), given that this biosynthetic pathway is essent...
