RESUMEN
We studied the eye movement parameters during reading of syntactically ambiguous sentences with feminine relative clause in Russian language. A priori difficulties of sentence structural analysis results in increase of time spent on reading as opposed to reading control sentences (unambiguous). Such a delay is caused by an increase of frequency of regressions (backward saccades) which are executed for rereading an ambiguous fragment ofsentence. This fact in turn leads to an increase in number of fixations and their duration. The total reading time for particular words composing the ambiguous fragment of sentence depended on disambiguation result (relative clause attachment, early/late closure). In case of early closure (when the subject attached relative clause to first noun) the total reading time for this noun exceeded one for second noun. In case of late closure (when the subject attached relative clause to second noun) the total reading time for both nouns didn't differ. Our results indicate that early closure domination in Russian language determines the greater total reading time for first noun of nominal group associated with relative clause.

The dynamics of cross-sectional, isochronic, and integral maps of electric potential distribution during the dipyridamole test was examined in 35 patients with verified coronary heart disease and 12 control patients. Basic differences were found in changes of excitation propagation velocities and positive potential amplitude in the groups examined. A local increase in R wave areas on the maps of positive potential differences was found to be the most significant mapping sign of transient myocardial ischemia (the sensitivity, specificity, and diagnostic accuracy being more than 97%). The diagnostic accuracy of an absolute or relative increase in the integral time and amplitude parameters of the mapping was 77% and 70%, respectively.
