We performed a systematic study to check whether neurons in the area TE (the anterior part of inferotemporal cortex) in rhesus monkey, regarded as the last stage of the ventral visual pathway, could be modulated by auditory stimuli. Two fixating rhesus monkeys were presented with visual, auditory or combined audiovisual stimuli while neuronal responses were recorded. We have found that the visually sensitive neurons are also modulated by audiovisual stimuli. This modulation is manifested as the change of response rate. Our results have shown also that the visual neurons were responsive to the sole auditory stimuli. Therefore, the concept of inferotemporal cortex unimodality in information processing should be re-evaluated., P. Kaposvári ... [et al.]., and Obsahuje bibliografii a bibliografické odkazy
Studie Heleny Matějčkové se zabývá obchodními kontakty mezi hudebním skladatelem Antonínem Dvořákem a londýnským nakladatelem Augener & Co., In the course of research focusing on the history of publication of the works of A. Dvořák, printed editions have been discovered for five works that were issued in 1885 and 1886 by the London publishing house Augener & Co. The literature and sources concerning the life and work of A. Dvořák, however, make no mention of this publisher or of its editions of Dvořák’s music. The study maps the history and activity of the publishing house, devoting the greatest attention to describing the new sources and to consideration of the possible circumstances of their publication – Augener’s editions of Dvořák’s compositions appear to have been prepared on the basis of already issued printings by the Prague publisher F. A. Urbánek – and of aspects of publishing practice at the time, especially with regard to copyright issues., Helena Matějčková., Rubrika: Studie, and Anglické resumé na s. 265, anglický abstrakt 247.
The reports of analgesic effects of benzodiazepines are inconsistent. There is evidence of a hyperalgesic effect induced by activation of supraspinal GABAA receptors and an antinociceptive effect induced by activation of receptors located in the spinal cord (dorsal horns). The aim of the study was to discover whether the systemic administration of a benzodiazepine agent alprazolam increases the systemic analgesic efficacy of non-opioid analgesic ibuprofen. Experimental studies combining these agents have not yet been published. We used three experimental methods - writhing test (with acetic acid), tail-flick test and plantar test to assess analgesic action. The drugs were administered orally. Augmentation of the analgesic effect of ibuprofen by alprazolam was proved for the writhing test at a dose of 30 mg/kg of ibuprofen and alprazolam 1 mg/kg. The reaction time of the combination was significantly prolonged in comparison with ibuprofen alone. The results of the tail-flick test and plantar test were negative. The effect of ibuprofen was not enhanced by alprazolam in tests of acute thermal pain. Our results have demonstrated that the analgesic action of ibuprofen is only weakly enhanced by alprazolam., T.

Let H be a finite abelian group of odd order, D be its generalized dihedral group, i.e., the semidirect product of C2 acting on H by inverting elements, where C2 is the cyclic group of order two. Let Ω (D) be the Burnside ring of D, Δ(D) be the augmentation ideal of Ω (D). Denote by Δn(D) and Qn(D) the nth power of Δ(D) and the nth consecutive quotient group Δn(D)/Δn+1(D), respectively. This paper provides an explicit Z-basis for Δn(D) and determines the isomorphism class of Qn(D) for each positive integer n., Shan Chang., and Obsahuje seznam literatury
