Abstract Boron is an essential micronutrient that has raised much interest, given the narrow balance between its necessity and toxicity. Both natural anthropogenic emissions of boron into water sources can eventually deteriorate quality endanger ecosystem. In this review, we first present a general outline importance boron, chemistry in water, contamination, consequences followed by recent prog...

Boron toxicity constitutes a limiting factor on seed germination. Salicylic acid-like plant growth regulators play an important role in alleviation the negative effects of boron stress. The research was carried out to determine germination properties seeds (pepper, eggplant, watermelon) with and without salicylic acid (SA) pre-application at different (B) concentrations. Experiments were conduc...

Boron nitride (BN) nanomaterials have been increasingly explored for potential biological applications. However, their toxicity remains poorly understood. Using Caenorhabditis elegans as a whole-animal model for toxicity analysis of two representative types of BN nanomaterials - BN nanospheres (BNNSs) and highly water-soluble BN nanomaterial (named BN-800-2) - we found that BNNSs overall toxici...

Boron Neutron Capture Therapy (BNCT) is a binary therapy that promises to be suitable in treating many non-curable cancers. To that, the discovery of new boron compounds able accumulate selectively tumour tissue still required. Hypoxia, deficiency oxygen tumor tissue, great challenge conventional treatment cancer, because hypoxic areas are resistant anticancer treatments. 2-Nitroimidazole deriv...

boron (b) toxicity is an important disorder that can limit plant growth in arid and semi-arid environments. it has been proven that use of tolerant rootstocks impede b uptake or transport to the aerial portions of plants. this may alleviate b toxicity in the scion, consequently improves the tolerance to excess b in the root zone. an experiment was conducted to find the effects of b toxicity on ...

We report the discovery that boron nitride nanotubes (BNNTs), isosteres of CNTs with unique physical properties, are inherently noncytotoxic. Furthermore, we developed a biomemetic coating strategy to interface BNNTs with proteins and cells. Finally, we showed that BNNTs can deliver DNA oligomers to the interior of cells with no apparent toxicity. This work suggests that BNNTs may be superior t...

Boron (B) toxicity is an important abiotic stress that drastically damages agricultural production worldwide, mostly in arid regions. Several studies have reported large losses wheat due to high B arable land. The identification of different B-toxicity-tolerant germplasm and using them breeding programs develop tolerant cultivars a potential solution toxicity. However, tolerance such largely re...
