In the presence of normal renal function, a high concentration of aluminum in drinking water has been implicated as a factor in the etiology of a neurological syndrome in one specific geographical area. The role of aluminum as a toxic agent in other neurological disorders, where renal function is normal, is controversial. Aluminum is absorbed from the gastrointestinal tract and is normally excr...

The reaction-bonded aluminum oxide (RBAO) process relies upon the oxidation of Al/Al2O3 powder compacts, and many of its associated advantages stem from the presence of the aluminum in the green powder. Higher aluminum contents in the starting powders allow for higher green strengths, densities, and lower overall shrinkage, all while producing a fine-grained, high-strength sintered material. Ho...

Aluminum exposure and apoptotic cell death has been implicated in several neurodegenerative conditions including Alzheimer's disease. In this study, we use cultured astrocytes to investigate the ability of aluminum to induce the apoptosis of astrocytes. The proportion of apoptotic cells and cell cycle distribution were determined by flow cytometric analysis. Our results showed that exposure to ...

Cenococcum graniforme, Suillus luteus, Thelephora terrestris, and three isolates of Pisolithus tinctorius were cultured on modified Melin-Norkrans medium at pH 3.4 and adjusted to 0 to 500 ppm (0 to 500 mug/ml) of aluminum or manganese sulfate. Except for T. terrestris, which was intolerant of aluminum at 150 and 250 to 500 ppm, and P. tinctorius isolate 250, which was intolerant of aluminum at...

A nanoscopic {Fe60} coordination cage (approximately 3 nm) was prepared by the self assembly of a partially blocked tricyanidoferrate(iii) complex and tris(alkoxo)-based iron(iii) coordination motifs. This cage is a rare example of a mixed cyanido/alkoxo-bridged high nuclearity complex and it exemplifies the great potential of this new synthetic route to generate uncommon molecular architecture...

Application of polynuclear metal clusters for phasing X-ray crystal structures of macromolecules is discussed. Their strong isomorphous and anomalous scattering signal is particularly useful for phasing structures of large macromolecules and complexes, especially at low resolution. The popularity of the metal clusters in macromolecular crystallography is expected to grow in the future. To cite ...

A little over a decade ago, Waldichuk (1990) reviewed the state of industrial and domestic pollution of the North Pacific and concluded that interfaces (e.g., air-water, water-sediment, shorelines) and coastal areas, especially those surrounded by dense population and industry, were most at risk. His list of critical contaminants – hydrocarbons and polynuclear aromatic hydrocarbons (PAHs), orga...

An effective and highly regio- and diastereoselective one-pot method for the synthesis of new polynuclear dispiroheterocyclic systems with five stereogenic centers (dispiro[imidazo[4,5-e]thiazolo[3,2-b]-1,2,4-triazine-6,3'-pyrrolidine-2',3''-indoles]) comprising pyrrolidinyloxindole and imidazo[4,5-e]thiazolo[3,2-b]-1,2,4-triazine moieties has been developed. The method relies on a 1,3-dipolar ...
