Butadiene (BD) and its 2-methyl analogue, isoprene, have been extensively studied in animals and BD in population studies. Both chemicals are metabolised by liver cytochrome P450 dependent monogenases to monoepoxide and diepoxide intermediates. The diepoxide intermediates of both compounds were mutagenic in Salmonella typhimurium. However,...

Amifostine (Ethyol, WR-2721) is in use in the clinic as a protector against platinum-induced toxicities. We have previously reported that amifostine induced a potentiation of the antitumour activity of carboplatin in human ovarian cancer xenografts. An influence of amifostine on the pharmacokinetics of carboplatin, resulting in higher platinum...

Several studies indicate that intake of calcium can inhibit iron absorption especially when taken simultaneously. In the CALEUR study, a cross-sectional study among girls (mean 13.5 y) and young women (mean 22.0 y) in six European countries, the association between calcium intake and iron status was studied. In 1,080 girls and 524 women,...

Malathion was applied to roses in three Finnish greenhouses by hand held lance sprayers. The potential dermal exposure of applicators to this insecticide was measured. Total urine production of each applicator was also collected up to 24 h post application. In the urine samples the specific metabolite of malathion, malathion monocarboxylic acid ...

The aim of the present study was to investigate how normal head and neck epithelial cells (NHNEC) respond to cisplatin compared to their neoplastic counterparts with respect to intracellular platinum (Pt) levels and growth inhibition. A colorimetric assay was used to assess growth inhibition after exposure to cisplatin for 72 h. Growth...

To assess the level of exposure to food contaminants (cadmium, lead, PCBs, DDT, hexachlorobenzene, nitrate and malathion) a total-diet study was carried out. A total of 226 food products were analysed individually; the concentration of contaminants in products not selected for analysis was estimated with the help of published data. The results...

High intakes of fruits and vegetables, or high circulating levels of their biomarkers (carotenoids, vitamins C and E), have been associated with a relatively low incidence of cardiovascular disease, cataract and cancer. Exposure to a high fruit and vegetable diet increases antioxidant concentrations in blood and body tissues, and potentially...

Background. Experiments in animals, international correlation comparisons, and case-control studies support an association between dietary fat intake and the incidence of breast cancer. Most cohort studies do not corroborate the association, but they have been criticized for involving small numbers of cases, homogeneous fat intake, and...

The Equiratio Mixture Model predicts the psychophysical function for an equiratio mixture type on the basis of the psychophysical functions for the unmixed components. The model reliably estimates the sweetness of mixtures of sugars and sugar-alchohols, but is unable to predict intensity for aspartame/sucrose mixtures. In this paper, the...

Characterizing school health promotion is its category-by-category approach, in which each separate health-related behavior is addressed independently. Such an approach creates a risk that extra-curricular activities become overloaded, and that teaching staff are distracted by continuous innovations. Within the health promotion sector there are...

Lactate eaters have an oral LD50 greater than 2000 mg/kg and the inhalation LC50 is generally above 5000 mg/m3 and they may be potential eye and skin irritants, but not skin sensitizers. No evidence of teratogenicity or maternal toxicity was observed in an inhalation (2-ethylhexyl-L-lactate) or dermal study (ethyl-L-lactate). Subacute inhalation...
