Relativistic effective core potential calculations of Hg and eka-Hg (E112) interactions with gold: spin-orbit density functional theory modeling of Hg-Aun and E112-Aun systems.

Interactions of eka-Hg (E112) and Hg atoms with small gold clusters were studied in the frame of the relativistic effective core potential model using the density functional theory (DFT) approach incorporating spin-dependent (magnetic) interactions. The choice of the exchange-correlation functional was based on a comparison of the results of DFT and large-scale coupled cluster calculations for E112Au and HgAu at the scalar relativistic level. A close similarity between the E112Aun and HgAun equilibrium structures was observed. The E112 binding energies on Aun are typically smaller than those for Hg by ca. 25%-32% and the equilibrium E112-Au separations are always slightly larger than their Hg-Au counterparts.

[Side effects of anticonvulsants in the treatment of idiopathic generalized epilepsy].

This investigation was ainced on detection of frequency and main features of side effects of anticonvulsants in therapy of idiopathic generalized epilepsy. There were observed 190 patients aged 5-29 years suffering from different forms of idiopathic generalized epilepsy. Side effects were revealed in 48.4% of patients as a result of the investigation. Almost half of patients (49.0%) who were administered valproic acid developed side effects. Neuroendocrine dysfunctions and digestive disturbances were the most frequent. Side effects were revealed within the first two months after administration of valproats. Only in 13.2% of cases the treatment and to be stopped at the expense of severeness of side effects. Barbiturates caused side effects in 39.6% of cases. Toxic damage of CNS was the most significant. Hyperkinetic syndrome with lack of attention was observed 37.9% of cases. Succinimides caused side effects in 37.9% of cases. Toxic damage of CNS was the most frequent--in 22.4% of cases, digestive disturbances was in 15.5% of cases. There are no really effective means for correction of above mentioned side effects.
