Owing to the increasing development of nanotechnology, there is a need to assess how engineered nanomaterials can interact with living cells. The main purpose of the present study was to assess whether metal cobalt nanoparticles (CoNP 100-500 nm) are genotoxic compared to cobalt ions (Co(2+)). Uptake experiments were carried out by incubating peripheral(More)
Even in specific risk groups, the relation between exposure to organic solvents and chronic renal diseases remains controversial. Thus, in a collaborative European study, we assessed the renal effects of occupational exposure to perchloroethylene (PCE) in dry-cleaners compared with matched controls who were simultaneously examined. Single high and low(More)
Adult male rabbits were exposed to high concentrations (750 ppm, 12 hours daily for 7 days) of toluene, xylenes, styrene, ethylbenzene, vinyltoluene (3-methylstyrene), and 7-methyl-styrene vapours or were dosed with 4 mM/kg/day i.p. of hippuric, methylhippuric, mandelic, phenylglyoxylic, and 7-methyl-mandelic acids. Styrene, vinyltoluene and ethylbenzene(More)
The induction of DNA and chromosome damage following in vitro exposure to carbon nanotubes (CNT) was assessed on the murine macrophage cell line RAW 264.7 by means of the micronucleus (MN) and the comet assays. Exposures to two CNT preparations (single-walled CNT (SWCNT > 90%) and multiwalled CNT (MWCNT > 90%) were performed in increasing mass(More)
The hypothesis that long-term low-level exposure to perchloroethylene (PERC) may impair the dopaminergic control of prolactin (PRL) secretion and negatively affect neurobehavioral performance, was tested in a cross-sectional survey of dry-cleaners. Sixty female workers exposed to PERC in dry-cleaning shops and thirty controls recruited in a cleaning plant(More)
BACKGROUND AND PURPOSE The creation of the nephrostomy access is a fundamental step of percutaneous nephrolithotripsy (PCNL). Dilation of the track is usually achieved with multiple incremental flexible exchange dilators of the Amplatz type, metal telescoping dilators of the Alken type, or a balloon. Currently, balloon dilation is regarded as the most(More)
Monoamine oxidase B (MAO-B) activity in platelets, serum dopamine-beta-hydroxylase (DBH) activity, and serum prolactin (PRL) were measured during a cross-sectional investigation in workers occupationally exposed to styrene. The study group consisted of 53 workers (33 men and 20 women) employed for 9.3 years on average (range 1-22) in reinforced plastics(More)
To investigate whether perchloroethylene (PCE) can induce renal disturbances and to compare morphological alterations with functional data, two groups of 12 male and female Fischer-344 mature rats were treated daily with PCE (500 mg/kg body wt in corn oil, p.o.) for 4 weeks. Sex- and age-matched control groups received corn oil only. Weekly, the urinary(More)
This study was aimed at evaluating whether controlled short-term exposure to ozone (O(3)) induces changes in biomarkers of lung inflammation and oxidative stress in exhaled breath condensate (EBC) and blood of healthy subjects. Twenty-two volunteers were exposed to 0.1 ppm of O(3) for 2 h while performing moderate intermittent exercise. EBC and blood were(More)
A cross sectional field study was planned to assess neurotoxic effects caused by low-level occupational lead exposure. Two groups of 66 workers and 86 controls were examined with a battery including a questionnaire on neurotoxic symptoms, the measure of performance at neurobehavioral testing, the detection of visual contrast sensitivity, and the dosage of(More)
