ABSTRACT
We studied auditory word repetition suppression effect using magnetoencephalography while subjects listened to "new" and "old" words whose familiarity they had to judge upon presentation. The lateralization of brain magnetic activity during processing of "new" and "old" words were estimated by computing RMS measure of whole-brain magnetic response within time window of semantic N400 (350-450 ms). A magnetic N400 was significantly stronger in the left than in the right hemisphere for the "new" words only. Repetition of "new" words led to sharp decrease of N400 response RMS in the left hemisphere but did not change right-hemispheric N400 RMS. The asymmetry index of this repetition suppression effect was lateralized to the left hemisphere for the majority of the participants and its magnitude was related to memory task performance. The findings point to a strong left-hemispheric dominance of word repetition suppression effect within the brain semantic networks at the level of whole-network response.

124 relaparotomies were performed in 70 children (1,9% of all the patients who had been operated on organs of the abdominal cavity). Eventrations made their appearance mainly in children of the first year of life, operated upon for malformations and having severe background diseases. The transrectal incision was found to have no advantages over the median incision in relation to the appearance of eventrations. Lethality after relaparotomied was 36,6%.

The work presents an analysis of 27 cases of acute hematogenic osteomyelitis with multiple injuries of bones. It has been noted that unlike primary localizations which often turn into a chronic process the secondary foci in such patients are frequently treated with good long-term issues. Lethality among patients with multiple osteomyelitis according to the authors' data is considerably higher (26%) than that in patients with the injury of one bone (0,8%).
