Nanosuspensions (NS) are one of the new generation drug carrier forms developed to overcome deficiencies drugs with poor water solubility or insolubility and considered be most successful approaches formulate compounds in recent years. Boron nitride (BN) is insoluble chemically more stable than carbon, it offers better biological superiority although application carbon structures biomedical fie...
Given the increasing importance of boron (B) toxicity, present study investigates roles glutathione (20 mM, GSH) and proline mM) in improvement wheat (Triticum aestivum cv. Altındane) resistance to B toxicity (10 mM B). The plants were raised hydroponic culture with control, B+glutathione, B+proline, proline. B+glutathione B+proline resisted detrimental influences on root shoot lengths, total c...
Plants activate glutathione (GSH)-dependent detoxification pathways at biochemical and molecular levels under boron (B) toxicity. Sulfate uptake transport are necessary for GSH biosynthesis in plants. Therefore, the transcriptional regulation of some sulfate transporters was determined this study to clarify importance these leaf root tissues Arabidopsis thaliana toxic B conditions. The expressi...
Carbon nanotubes (CNTs) are promising as the drug carriers to cells for various biomedical applications including cancer therapy. Toxicity of CNTs was a debatable issue as previous studies were performed using long and unfunctionalized CNTs, which tend to entangle in the biological systems and lead to various lung lesions and blocking of the airways. More recent in vitro and in vivo studies ind...
The aim of this study is to analyze the effect excess boron (B) on nutrient uptake, growth, and physiological performance grapevines. Merlot Cabernet Franc grapevines, either own-rooted or grafted onto 1103P 101-14 Mgt rootstocks, were exposed in a hydroponic pot experiment 0.5 mM for sixty days. Twenty-five days following beginning B treatment, first symptoms toxicity appeared, including leaf ...
The trace mineral boron is a micronutrient with diverse and vitally important roles in metabolism that render it necessary for plant, animal, and human health, and as recent research suggests, possibly for the evolution of life on Earth. As the current article shows, boron has been proven to be an important trace mineral because it (1) is essential for the growth and maintenance of bone; (2) gr...
Boron is an interesting element with unusual polymorphism. While three-dimensional (3D) structural motifs are prevalent in bulk boron, atomic boron clusters are found to have planar or quasi-planar structures, stabilized by localized two-center-two-electron (2c-2e) σ bonds on the periphery and delocalized multicenter-two-electron (nc-2e) bonds in both σ and π frameworks. Electron delocalization...
