This study investigated biliary secretory function in workers occupationally exposed to aluminium dust and fumes. It included a group of 34 male workers aged (44.1+/-7.8) years and exposed up to 4.6 mg m-3 of aluminium dust and fumes in workplace air for (21.6+/-2.5) years, and a group of 30 unexposed control male workers. Serum and urine aluminium levels were measured in both groups before and...

This in vivo study was designed to investigate the potential of aluminium (Al), in the absence of added iron, to participate in either antioxidant or pro-oxidant events. Some markers of oxidative stress were determined in liver and brain of rats exposed to aluminium lactate, either alone or in the presence of dietary supplements of selenium (se) as selenite. Exposure to aluminium for 21 days re...

Nowadays, fuel consumption and carbon dioxide emissions are two of the main focal points in vehicle design, promoting the reduction in the weight of vehicles by using lighter materials. The aim of the work is to evaluate the influence of different aluminium foams and injection parameters in order to obtain compound castings with a compromise between the obtained properties and weight by high-pr...

Annals of the RHEUMATIC DISEASES Leader Does aluminium have a pathogenic role in dialysis associated arthropathy? Dialysis has improved the prognosis and quality of life for patients with chronic renal insufficiency, but at the price of various complications. The first to be recognised were the acute myoclonic encephalopathies,' 2 whose main cause is aluminium overload. This overload results fr...

the activity of aspartate aminotransferase (ast) in human serum has been widely determined as a diagnostic aid in liver disease. in this study, the effect of aluminium on ast isoenzymes in relation to aluminium intoxified patients has been investigated. using gel filtration chromatography technique with sephacryl s-300, mitochondrial aminotransferase (m-ast) and cytosolic aminotransferase (c-as...

This paper examines the development of the new EnPot heat exchanger technology for aluminium smelters and the potential impact it could have on the sustainability and economics of primary aluminium production. The EnPot technology can be used to help the aluminium smelting industry be part of the solution to accommodate increased intermittency in our future renewable energy generation, post COP...

The disproportionation of AlCl(THF)n (THF is tetrahydrofuran) in the presence of lithium amidinate species gives aluminium(III) amidinate complexes with partial or full chloride substitution. Three aluminium amidinate complexes formed during the reaction between aluminium monochloride and lithium amidinates are presented. The homoleptic complex tris(N,N'-diisopropylbenzimidamido)aluminium(III),...

The long-term effects of early postnatal exposure to aluminium on acetyl choline esterase (AChE) activity and on biogenic amines were studied in different brain regions. The subjects were eight days old male Wistar rat pups. They were grouped into normal control and aluminium exposed groups. For aluminium exposure, the pups were gastric intubated with aluminium chloride (40 mg/Kg body weight) f...

A retrospective study was conducted in order to characterize the retention of fibrous and nonfibrous mineral particles in the respiratory tract in subjects with previous occupational exposure in the aluminium industry. Bronchoalveolar lavage (BAL) fluid (three samples) or lung parenchyma (two samples) were studied using analytical transmission electron microscopy in five patients. A high concen...

The project was carried out to compare the performance of molted layers by aluminium oxide supplementation in cages and on litter floor system. Seventy two Single Comb White Leghorn commercial layers (60 weeks old) were divided into six experimental units of 12 layers each. These experimental units were randomly divided into two groups, each consisting of three experimental units, one group was...
