in recent years, a potential connection between human intake of aluminum and alzheimer’s disease has drawn attention to the aluminum concentration in drinking water. it is therefore of interest to investigate the aluminum concentration m drinking water, produced under different circumstances. a random selection of 152 water samples were taken by the supply source including ground, surface and a...

background: several adjuvants have been evaluated for vaccine formulations but alu-minum salts will continue to be used for many years due to their safety, low cost and adjuvanticity with different antigens. two commonly used aluminum adjuvants, alumi-num hydroxide and aluminum phosphate have different adjuvanticity properties. com-mercial recombinant protein hepatitis b vaccines containing alu...

We have studied the impact of dissolved aluminum on interfacial properties of two aluminum bearing minerals, corundum and kaolinite. The effect of intentionally adding dissolved aluminum on electrokinetic potential of basal plane surfaces of sapphire was studied by streaming potential measurements as a function of pH and was complemented by a second harmonic generation (SHG) study at pH 6. The ...

Zeolites are aluminosilicates that are used in many applications involving catalysis, separation, and gas storage. Unlike the Si/Al ratio of their framework, the location of the aluminum atoms is not well described. It has proved difficult to establish the local structure surrounding the aluminum sites by diffraction methods, since aluminum and silicon are very close in X-ray scattering power a...

The purpose of the present study was to investigate the in vitro and in vivo effects of aluminum sulfate on delta-aminolevulinic acid dehydratase (ALA-D) activity from the brain, liver and kidney of adult mice (Swiss albine). In vitro experiments showed that the aluminum sulfate concentration needed to inhibit the enzyme activity was 1.0-5.0 mM (N = 3) in brain, 4.0-5.0 mM (N = 3) in liver and ...

Aluminum is the most abundant metal in the Earth's crust and a highly sought after fuel source due to its extreme energy density. It has the ability to produce large quantities of hydrogen and heat when reacted with water making it an attractive fuel for underwater vehicles and ocean sensor platforms. The biggest challenge in using aluminum as a fuel has been overcoming the rapidly-forming oxid...

Some vaccines contain aluminum adjuvants to enhance the immunological response, and it has been postulated that this aluminum could contribute to adverse health effects, especially in children who receive a vaccination series starting at birth. The pharmacokinetic properties and end-point toxicities of aluminum are presented. In assessing the relevance of dietary and medical aluminum exposure t...

Increasing use of aluminum shape castings in automotive and aerospace industries has drawn great attention to fatigue properties of cast aluminum components. The fatigue resistance of aluminum castings strongly depends upon the presence of casting flaws and characteristics of microstructural constituents. The existence of casting flaws significantly reduces fatigue crack initiation life. In the...

Aluminum is a toxic metal and has been implicated as the causative agent in the dialysis encephalopathy syndrome. In the study reported here, the transfer of aluminum to the blood from dialysis fluid during hemodialysis was demonstrated even when deionized water was used in the preparation of the dialysate. Studies were carried out on the binding of aluminum to serum proteins and other constitu...
