A high-performance liquid chromatographic (HPLC) method was developed for the determination of disodium mercaptoundecahydrododecaborate (BSH) in biological fluids. Monobromobimane was used as a precolumn derivatizing agent. A stable derivative was obtained. The derivative was separated on a C18 ...

Mercaptoundecahydrododecaborate (BSH) is an important agent for the boron neutron-capture therapy (BNCT). A sensitive high-performance liquid chromatographic (HPLC) method was developed for measuring BSH concentrations in rat tissues. Various tissue samples containing the drug were homogenized i...

A simple and rapid method for the quantitative measurement of mercaptoundecahydrododecarborate (BSH), (which presently is one of the most useful agents for Boron Neutron Capture Therapy) in human plasma was developed by using Fourier transform infrared spectroscopy. Different spacer thicknesses ...

A series of mercaptoundecahydrododecaborate (B12H11SH2−, BSH) bearing mono- and dicarboxyalkyl derivatives was prepared, characterized, and their reactivity towards amidation and esterification in DMF was evaluated. Symmetrical alkylation of BSH was achieved by treatment with primary haloalkyl c...

A simple, specific and accurate method for the quantitation of sodium mercaptoundecahydrododecaborate, which is a very hygroscopic agent for boron neutron-capture therapy, was developed by using capillary isotachophoresis with sodium p-toluenesulphonate as an internal standard. Compound 1a was s...

The interaction of mercaptoundecahydrododecaborate (B12H11SH2−, BSH) with phosphatidylcholine was investigated in this study in order to illuminate possible uptake mechanisms of BSH in tumor cells. BSH has been used clinically in Japan as a boron containing agent in patients with malignant brain...

The adsorption removal of indole and quinoline in octane with and without toluene over zeolites NaY and Yttrium Ion-exchanged Y (YY) using batch adsorption experiments was studied at 25 oC and 1 atm. YY was prepared by treating NaY with Y(NO3)3 solution twice via liquid ion-exchange method. NaY ...

Irrespective of the success on reduction of contact resistivity, lack of chemical passivation of evaporated metal oxides heavily hinders their applications as passivating contacts, such contacts can be an alternative route for high efficiency and cost effective silicon solar cells. Here, we demo...

The paper presents a promising method of Ta–based foams preparation by the thermal dealloying method. The concept of the foams formation was to remove one of the alloying elements from the tantalum alloy under high temperature. This element was magnesium that has a relatively low boiling temper...

AZ31 magnesium alloys were implanted with tantalum ions with doses of 1 × 1016, 5 × 1016 and 1 × 1017 ions/cm2, using a metal vapor vacuum arc (MEVVA) at an extraction voltage of 45 kV. Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) analysis suggested that tantal...

Luminescence during a constant current electrolytic oxidation of tantalum in phosphoric acid and oxalic acid is investigated. Weak anodic luminescence (galvanoluminescence) of barrier oxide films during the electrolytic oxidation is correlated to the existence of surface imperfections. Galvanolu...

This paper presents a promising method of tantalum – bioglass porous composites preparation by thermal dealloying. The first step of this study was the Ta-Bioglass-Mg nanopowder preparation using the mechanical alloying process in a Spex shaker type mill. The next step was the formation of the ...

Members of the Ba2Zn1−xCdxTa2O9 (0 ≤ x ≤ 1) series have been synthesized by solid state reactions at 1473K. Powder x-ray diffraction studies show a cubic perovskite cell with a ~ 4.1Å which increases with increase in x. Electron diffraction studies show the presence of hexagonal ordered perovs...

The solubility of a variety of metal acetylacetonate, tetramethylheptanedionate, cyclopentadienyl and cyclooctadiene complexes in supercritical carbon dioxide was measured. The complexes included the metals potassium, rubidium, titanium, zirconium, vanadium, chromium, manganese, iron, ruthenium,...

ObjectiveThis study aimed to assess the changes induced in HSA upon fructose-modification and to use the modified protein as an antigen for studying the presence of antibodies in diabetic patients. Further, magnitude of oxidative stress was also assessed.

The cytoprotective activity of F16BP has been documented in severe conditions such as convulsions, reperfusion injury, septic shock, diabetic complications, hypothermia-induced injury, UV-provoked skin damage and in other processes including apoptosis and excitotoxicity. F16BP shows very efficie...

d-Fructose dehydrogenase (FDH), a membrane-bound heterotrimeric enzyme, shows strong activity in direct electron transfer (DET)-type bioelectrocatalysis. An FDH variant (Δ1c2cFDH) which lacks 199 amino acid residues including two heme c moieties from N-terminus was constructed, and its DET-type...

The solution chemistry of ferric fructose has been examined at various hydroxide-to-iron ratios using several physical techniques. The reactivity of ferric fructose complexes with transferrin, the serum iron binding protein, has provided a quantitative measure of polymeric fractions and insight ...

Reinvestigation of the chelation of iron by D-gluctose and D-glucose led to definable conditions for the preparation of ferric-D-fructose and ferric-D-glucose-D-fructose complexes that could be isolated and redissolved to give neutral solutions. The complexes isolated had defined and reproducibl...
