Aluminum and zinc are two important trace elements in an organism. Although several studies have demonstrated their impacts on the intelligence, very little was known about their effects on the integrity of blood-brain barrier (BBB). To study the effects of aluminum and zinc on the permeability of BBB, different doses of aluminum and appropriate zinc were administered to rats. Evans blue was de...

Vapor grown carbon fiber reinforced pure aluminum matrix composites were fabricated by the hot-pressing method below the melting temperature of pure aluminum. The surface structures of the vapor grown carbon fibers and the interfacial structures between the fibers and the matrix in the composite were observed. The precipitation mechanism of crystalline aluminum carbide was also investigated. An...

Background: Aluminum has known neurotoxicity and may impair short-term bone health. In a randomised trial we showed reduced neurodevelopmental scores in preterm infants previously exposed to aluminum from parenteral nutrition solutions. Here, in the same cohort, we test the hypothesis that neonatal aluminum exposure also adversely affects long-term bone health, as indicated by reduced bone mass...

Aluminum is currently the most widely used non-ferrous metal, and its extraction and purification from geological stores exceeds that of any other metal except iron (1, 2). In 2013, global primary aluminum production was ~52 million tons (104 billion pounds) or about 15 pounds for very person on the earth (1–4). The global outlook for aluminum demand from developing countries such as Brazil, Ch...

Aluminum castings have played an integral role in the growth of the aluminum industry since its inception in the late 19th century. The first commercial aluminum products were castings, such as cooking utensils and decorative parts, which exploited the novelty and utility of the new metal. Those early applications rapidly expanded to address the requirements of a wide range of engineering speci...

Aluminum in acidic conditions is toxic to plants. Aluminum tolerance in some plant species has been ascribed to arbuscular mycorrhizal fungal symbiosis. In this study, the application of aluminum was found to inhibit mycelia development of saprobe fungi Fusarium concolor and Trichoderma koningii and the hyphal length of the arbuscular mycorrhizal fungi Glomus mosseae and Glomus deserticola in v...

POWDER METALLURGY (P/M) technology provides a useful means of fabricating net-shape components that enables machining to be minimized, thereby reducing costs. Aluminum P/M alloys can therefore compete with conventional aluminum casting alloys, as well as with other materials, for costcritical applications. In addition, P/M technology can be used to refine microstructures compared with those mad...

The syntheses and characterization of both tris(diethylamino)aluminum and tris(diisopropylamino)aluminum are presented in this letter. Characterization includes vapor pressure measurements and comparison of the two non-pyrophoric precursors showing them to be viable alternatives to trimethylaluminum. Ultimately, tris(diisopropyl)aluminum was successful in the atomic layer deposition of alumina ...

This study was designed to determine the influence of aluminum hydroxide and famotidine on the bioavailability of tosufloxacin. Coadministration of aluminum hydroxide reduced the bioavailability of tosufloxacin by 31.6% (P < 0.05). Famotidine did not alter tosufloxacin absorption. To avoid potential treatment failures, the concurrent use of tosufloxacin and aluminum hydroxide should be avoided ...

BACKGROUND Some parents are requesting aluminum testing in their children with developmental issues. Although aluminum can be measured in plasma, serum, or urine, there is scant scientific information about normal ranges. We sought to determine the basis for laboratory reference ranges and whether these ranges are applicable to children. METHODS From texts, published lists, and Internet sourc...
