Exposure of pregnant rats to the anesthetic nitrous oxide on the ninth day of gestation causes fetal resorption, skeletal anomalies, and macroscopic lesions including encephalocele, anophthalmia, microphthalmia, and gastroschisis. The inert gas xenon, which has anesthetic properties similar to those of nitrous oxide, does not cause teratogenic effects under(More)

The heterogeneity of natural geological formations has a major impact in the contamination of groundwater by migration of pollutants. In order to get an asymptotic behavior of the solute dispersion, numerical simultations require large scale computations. We have developed a fully parallel software, where the transport model is an original parallel particke(More)
Two isoforms of ATP diphosphohydrolase (ATPDase; EC have been previously characterized, purified, and identified. This enzyme is an ectonucleotidase that catalyzes the sequential release of gamma- and beta-phosphate groups of triphospho- and diphosphonucleosides. One of its putative roles is to modulate the extracellular concentrations of purines(More)
The teratogenic activity of the antitumor agent cisplatinum-2-thymine (platinum thymine blue) was investigated in rats. Pregnant Wistar-derived albino rats were given single ip injections of an aqueous solution of platinum thymine blue (PTB) at one day of pregnancy from day 5 through day 14 (sperm day=day 0). The dosages used ranged from 20 to 80 mg/kg(More)
