Boron level in irrigation water is an important factor for high yield and quality agricultural production. Concentration below 1ppm provides plants with proper development and higher concentration poses toxicity problem. This necessitates for the use of accurate technique for assessment of boron in the irrigation water. Several analytical methods have been used for determination of boron in wat...

Pectic polysaccharides containing apiose, xylose, and uronic acids are excellent candidates for boron fixation. Duckweeds the fastest-growing angiosperms that can absorb diverse metals contaminants from water have high pectin content in their cell walls. Therefore, these plants be considered (B) accumulators. This work aimed to investigate relationship between B assimilation capacity with apios...

High-dose boric acid (BA) exposure produces testicular lesions in adult rats characterized by inhibited spermiation (IS) that may progress to atrophy. In vivo and in vitro studies addressed possible mechanisms. In vivo, boron tissue disposition was examined, since no detailed data existed, and relevant boron concentrations for in vitro studies needed to be set. Since BA induces riboflavinuria a...

Boron neutron capture therapy (BNCT) is based on the nuclear reaction, such that B-10 irradiated with low-energy thermal neutrons produces alpha particles with high linear energy transfer and lithium-7. Clinically, BNCT is used primarily for treatment of high-grade glioma or brain metastases from melanoma and, more recently, head, neck and liver cancers. Since reactors have long been used to pr...

BACKGROUND Boron neutron capture therapy (BNCT) is based on the nuclear reaction that occurs when boron-10 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 primarily on the treatment of high-grade gliomas and either cutaneous primaries or cerebral metastases of melanoma, most...
