The role of lipid peroxidation in the mechanism of arsenic toxicity was investigated in female rats pretreated with N-acetylcysteine (NAC, a glutathione [GSH] inducer) or with buthionine sulfoximine (BSO, a GSH depletor) . Rats were challenged with sodium arsenite, and sacrificed 1 hr after this results. Results showed that arsenic decreased GSH levels and increased lipid peroxidation in liver,

The authors report the results of a case-cohort study of 338 lung cancer deaths in 1950-1988 and a random sample (sub-cohort) of 1,138 from among 16,297 men who had worked at least one year between 1950 and 1979 in manual jobs at a large aluminum production plant. In the past, certain workers were exposed to substantial quantities of coal tar pitch volatiles,

To confirm the relationship between exposure to coal tar pitch volatiles and bladder cancer among primary aluminum production workers, we carried out a case-control study among blue-collar workers who had worked more than 1 year between 1950-1979 in a major plant using mostly the Soderberg process in the Province of Québec. Cases of bladder cancer (ICD code 188) diagnosed between 1970-1979 (n = 69) were mostly included in a previously reported study.

OBJECTIVES: This study investigated associations between exposure to polycyclic aromatic hydrocarbons (PAH) and the incidence of lung, bladder, kidney, and pancreatic cancer among Norwegian aluminum plant workers.

METHODS: Cancer incidence was investigated from 1953 to 1996 among 11,103 men employed for more than 3 years in the industry, giving 272,554 person-years during follow-up.

A significant co-morbidity of Alzheimer's disease and cerebrovascular impairment suggests that cerebrovascular dysregulation is an important feature of dementia. Amyloid β protein (Aβ), a relevant risk factor in Alzheimer's disease, has neurotoxic properties and is thought to play a critical role in the cognitive impairments. Previously, we demonstrated that the 42mer of Aβ (Aβ42) complexed with aluminum (Al-Aβ42) is much more cytotoxic than non-complexed Aβ42.

Inflammatory and oxidative events are up-regulated in the brain of AD patients. It has been reported that in animal models of AD, exposure to aluminum (Al) or copper (Cu) enhanced oxidative events and accumulation of amyloid beta (Aβ) peptides. The present study was designed to evaluate the effect of a 3-month exposure of mice to copper sulfate (8 μM),

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.
