Advantages of the Liposomal Form of Xymedon in Leukopoiesis Restoration against the Background of Myelosuppressive Therapy with Liposomal Antineoplastic Drugs in Experiment.

We analyzed advantages of the liposomal form of Xymedon (50 and 100 mg/kg) over free Xymedon (in the corresponding doses) in leukopoiesis restoration in rats with Walker-256 carcinoma treated with liposomal combination of doxorubicin (4 mg/kg) and cyclophosphamide (45 mg/kg) (single intravenous injection on day 11 after transplantation of tumor cells). Liposomal and free Xymedon were injected intravenously over 5 days starting from day 11 of the experiment. Changes in leukopoiesis in peripheral blood and myelograms were assessed on days 3 and 7 after chemotherapy.

[Event-related brain potentials when Russian verbs being conjugated: to the problem of language processing modularity].

In the light of alternative conceptions of "two-system" and "single-system" models of language processing the efforts have been undertaken to study brain mechanisnis for generation of regular and irregular forms of Russian verbs. The 19 EEG channels of evoked activity were registered along with casual alternations of speech morphology operations to be compared. Verbs of imperfective aspect in the form of an infinitive, belonging either to a group of productive verbs (default, conventionally regular class), or toan unproductive group of verbs (conventionally irregular class) were presented to healthy subjects.

[Statistically significant reproducible differences of pericranial muscles EMG in beta and gamma frequency ranges when different emotional and cognitive states are compared].

Results of comparison of power of EMG of six pericranial muscles in electroencephalographic frequency ranges beta1, beta2 and gamma are presented corresponding to performances of the tasks bound to inductions of affective experiences-external by means of presentation of images and internal by means of autobiographical memoirs revived. The tasks were focused on an induction of affective experiences with different emotional valencies--positive, negative and neutral. The EMG was derived, registered and processed by means of a computer electroencephalography techniques.

[Common and individual in EEG spectral differences while performing verbal and spatial tasks].

It is shown previously that types of carried-out spatial-figurative and verbal-logic tasks can be distinguished by means of the trained automatic classifier, using individual for each examinee characteristics of EEG power spectra. Research with application of a subset of the same tasks, but aimed to identify the EEG spectral power group differences has been carried out with 31 participants. Contrast distribution of statistically significant differences on frequency bands qualitatively coincides with ranging of the bands by estimates of efficiency of recognition with the trained classifier, except for a range theta.
