Participants in the study were children with ASD (F 84.0 according to ICD-10), aged 5-16 years (n = 25) and typically developing (TD) children aged 4-7 years (n = 60). The analysis of child behavior, vocalizations and speech was performed for the purpose of stimulus selection. The peculiarities of emotion state recognition of TD children and ASD children by adults (n = 514) were revealed. It is shown that the emotional states of ASD children are better recognized by the features of vocalizations and speech than by facial expression. This finding is promising in terms of development of children with methods for assessing the characteristics of their voices, and to create an automatic speech recognition system for the purpose of teaching children with atypical development.</p>","PeriodicalId":21358,"journal":{"name":"Rossiiskii fiziologicheskii zhurnal imeni I.M.

In the present study, the inhibitor of HSPs expression quercetin was used in a rat model of nigrostriatal system proteasome dysfunction. This model was created by the microinjections of the specific proteasome activity inhibitor lactacystin, that was injected locally to the substantia nigra pars compacta (SNpc). The model reproduces the under-threshold level of nigrostriatal degeneration and neurochemical features characteristic of the preclinical PD stage. It was shown for the first time that quercetin pretreatment inhibited the LC-induced expression of Hsp70 in the SNpc neurons and increased in 1.5 times the dopamine (DA)-ergic neurons death and in 2.7 times the striatal DA-ergic axons degeneration. These changes were accompanied by the depletion of compensatory mechanisms and HSP70 content in the SNpc neurons and the appearance of the motor dysfunctions, typical for the clinical PD stage. The results of this investigation indicate the important role of Hsp70 in mechanisms of the nigrostriatal system protection in proteasome dysfunction, characteristic for the pre-clinical PD stage. The data obtained can be considered as the scientific basis for the development of new technologies for early PD therapy by exogenous Hsp70.</p>","PeriodicalId":21358,"journal":{"name":"Rossiiskii fiziologicheskii zhurnal imeni I.M.
