“…Boric acid was also added to each sample to further limit formation of vanadium carbide that could reduce the sensitivity of the method. 12 Method blanks and Standard Reference Materials SRM 1643d, Trace Elements in Water, SRM 1486, Bone Meal, and SRM 1566b, Oyster Tissue (National Institute of Standards and Technology, Gaithersburg, MD) were used for method quality control and to assess vanadium recovery. Femur vanadium concentrations were compared to those previously reported in the rat.…”

This study quantified the effects of local intramedullary delivery of an organic vanadium salt, which may act as an insulin-mimetic on fracture healing. Using a BB Wistar rat femoral fracture model, local vanadyl acetylacetonate (VAC) was delivered to the fracture site and histomorphometry, mechanical testing, and immunohistochemistry were performed. Callus percent cartilage was 200% higher at day 7 (p < 0.05) and 88% higher at day 10 (p < 0.05) in the animals treated with 1.5 mg/kg of VAC. Callus percent mineralized tissue was 37% higher at day 14 (p < 0.05) and 31% higher at day 21 (p < 0.05) in the animals treated with 1.5 mg/kg of VAC. Maximum torque to failure was 104% and 154% higher at 4 weeks post-fracture (p < 0.05) for the healing femurs from the VACtreated (1.5 and 3.0 mg/kg) animals. Animals treated with other VAC doses demonstrated increased mechanical parameters at 4 weeks (p < 0.05). Immunohistochemistry detected 62% more proliferating cells at days 7 (p < 0.05) and 94% more at day 10 (p < 0.05) in the animals treated with 1.5 mg/kg VAC. Results showed 100% more vascular endothelial growth factor-C (VEGF-C) positive cells and 80% more blood vessels at day 7 (p < 0.05) within the callus subperiosteal region of VAC-treated animals (1.5 mg/kg) compared to controls. The results suggest that local VAC treatment affects chondrogenesis and angiogenesis within the first 7-10 days post-fracture, which leads to enhanced mineralized tissue formation and accelerated fracture repair as early as 3-4 weeks post-fracture. ß

“…[7][8][9] Although a combination of using chemical modifiers and pre-coating the graphite furnace can improve boron absorbance measurements, the advantages of using GF-AAS, such as its relative simplicity and the speed at which it can be used to analyze samples, are lost when a pre-coating treatment is required. New chemical modifiers that can stabilize boron reactions in the graphite furnace without requiring the furnace to be pre-coated are required.…”

“…The loss of vanadium in graphite furnace during the atomization process has been considered to be due to the formation of its carbide. Therefore, for the determination of vanadium by a graphite furnace AAS, the uses of a pyrolytic graphite tube and tubes coated with such elements as tungsten, 9 zirconium, 10 lanthanum 11 and boron, 12 have been recommended. In this paper, the direct determination method of the vanadium in the heavy oil was studied by utilizing graphite tubes coated with tungsten.…”

A simple and rapid method was established for the direct determination of vanadium in an oil sample using the tungstencoated graphite-furnace AAS. The interference of the sulfur compound could be suppressed by choosing the ashing temperature. If the sulfur concentration in the sample is diluted to 1.0 wt% or less, the interference can be suppressed. This proposed method should make important contributions to the quality control of petroleum refineries.
