Industrialized societies produce many convenience foods with aluminum additives that enhance various food properties and use alum (aluminum sulfate or aluminum potassium sulfate) in water treatment to enable delivery of large volumes of drinking water to millions of urban consumers. The present causality analysis evaluates the extent to which the routine, life-long intake, and metabolism of alu...

BACKGROUND During the last years, human newborns have been overexposed to biologically reactive aluminum, with possible relevant consequences on their future health and on their susceptibility to a variety of diseases. Children, newborns and particularly preterm neonates are at an increased risk of aluminum toxicity because of their relative immaturity. DATA SOURCES Based on recent original p...

Most humans living in industrialized societies are routinely exposed to bioavailable aluminum salts in the form of additives-in commercially-prepared foods, alum-clarified drinking water, certain pharmaceuticals, sunscreens, and other topical applications. Minute amounts of this aluminum are absorbed into the circulation. Trace aluminum levels cross the blood-brain barrier and progressively acc...

as a high temperature structural ceramic, cermets exhibit less brittleness than ceramic-ceramic composites or monolithic ceramics owing to the presence of a ductile metal second phase in their microstructure. these cermets can, therefore, be used in applications where the abrasive, creep and thermo-mechanical resistance are required. in the present study, aluminum-alumina cermets with different...

It was shown that the rate of excretion of aluminum in the urine was assumed to have a limiting value. Therefore, an excess intake of aluminum indicated that the aluminum content in the body remained high for several days after the absorption of aluminum from the intestine. Accumulation of aluminum in the body has been linked to disease conditions. The toxic effects of aluminum to neuronal cell...

Using a staining technique developed in 2004, we examined hippocampal tissue from autopsy-confirmed cases of Alzheimer's disease (AD) and controls. The stain disclosed aluminum in cells and subcellular structure. All pyramidal neurons in these aged specimens appeared to exhibit at least some degree of aluminum staining. Many displayed visible aluminum only in their nucleolus. At the other extre...

In recent year’s aluminum and aluminum alloys are widely used in automotive industries. These are light weight (density of about 2.7g/cc),having good malleability and formability, high corrosion resistance and high electrical and thermal conductivity. High machinability and workability of aluminum alloys are prone to porosity due to gases dissolved during melting processes. However, in the engi...

Aluminum use and primary aluminum production results in the generation of various particles, fumes, gases, and airborne materials with the potential for inducing a wide range of lung pathology. Nevertheless, the presence of diffuse parenchymal or interstitial lung disease related to these processes remains controversial. The relatively uncommon occurrence of interstitial lung diseases in alumin...

Nanocrystalline TiO2 films, surface modified with Al3+, were manufactured by depositing a TiO2 suspension containing small amounts of aluminum nitrate or aluminum chloride onto conducting glass substrates, followed by drying, compression, and finally heating to 530 degrees C. Electrodes prepared with TiO2 nanoparticles coated with less than 0.3 wt % aluminum oxide with respect to TiO2 improved ...

abstract        background and objective: aluminum salts are among the most common useful additive compounds in preparation of human and animal vaccines. aluminum phosphate and aluminum hydroxide are two additives that show good immunoadjuvant effects with many antigens. aluminum-containing vaccines lead to a better and longer immune response compared to adjuvant-lacking vaccines. the chromogen...
