Boron (B) is an essential nutrient for normal growth of higher plants, and B availability in soil and irrigation water is an important determinant of agricultural production. To date, a primordial function of B is undoubtedly its structural role in the cell wall; however, there is increasing evidence for a possible role of B in other processes such as the maintenance of plasma membrane function...

Boron may be beneficial for bone growth and maintenance, central nervous system function, and the inflammatory response, and silicon may be beneficial for bone maintenance and wound healing. Fluoride is not an essential element but amounts provided by contamination may be beneficial for bone strength. Fluoride toxicity may be a concern in parenteral nutrition. Further studies are warranted to d...

Managing urban pests with “environmentally-friendly” compounds has gained importance in recent years with the global deregistration of persistent organochlorine insecticides. Boron compounds, especially boric acid, zinc borate, and disodium octaborate tetrahydrate, are considered excellent options for preserving lumber from insect attack as well as decay by fungi and bacteria. Remedial borate a...

The element boron plays a role in medical and biological fluids [1] which is not yet well investigat­ ed. Further it is questionable if boron is needed as a trace element in the hum an food. But due to its toxicity, boron containing drugs are largely for­ bidden in this country [2], With the daily food, boron is incorporated in amounts which are esti­ mated to 1 through 40 mg per day [3], where...

Aluminum (Al) toxicity is the primary factor limiting crop growth in acidic soils. Boron (B) alleviates Al toxicity in plants, which is mainly considered to be due to the formation of Rhamnogalacturonan II-B (RGII-B) complexes, which helps to stabilize the cytoskeleton. It is unclear yet whether this is due to the increasing of net negative charges and/or further mechanisms. Kinetics of Al accu...

25 Laurentia Gales 258 Șos.Fundeni, 2nd District, Bucharest, Romania e-mail: [email protected] Abstract. Boron neutron capture theory (BNCT) is a binary therapy applied in malignant tumours, resistant to other treatment methods, namely chemotherapy and radiotherapy. One of the main components is Bor-10, a stable isotope that can be inserted in the tumour cells by using specific transpor...

Boron is an important micronutrient for plants, but high B levels in soils are often responsible for toxicity effects in plants. It is therefore important to understand reactions that may affect B availability in soils. In this study, Attenuated Total Reflectance Fourier transform Infrared (ATR-FTIR) spectroscopy was employed to investigate mechanisms of boric acid (B(OH)3) and borate (B(OH)4 )...

The treatment of malignant brain tumors using conventional therapies and surgery often leads to tumor recurrence and/or unwanted side effects. Boron neutron capture therapy (BNCT) is a binary and localized form of treatment for brain tumors and other difficult-to-treat cancers that uses nontoxic boron-containing agents. Boronated porphyrins and derivatives constitute a class of highly promising...
