The ability of Azotobacter chroococcum strain 7B, producer of poly(3-hydroxybutyrate) (PHB), to synthesize its copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (P(3HB-co-3HV)) was studied. It was demonstrated, for the first time, that A. chroococcum strain 7B was able to synthesize P(3HB-co-3HV) with various molar rates of HV in the polymer chain when(More)
Parkinson’s disease is one of the most common human neurodegenerative disorders caused by the loss of dopaminergic neurons from the substantia nigra pars compacta of human brain. However, causes and mechanisms of the progression of the disease are not yet fully clarified. To date, investigation of the role of miRNAs in norm and pathology is one of the most(More)
A biodegradable polymer of bacterial origin, poly(3-hydroxybutyrate) (PHB), is intensively studied as biomaterial for tissue engineering. However, factors determining its biocompatibility still require better understanding. To analyze the PHB films biocompatibility, the polymer material was modified by hydrophilic polymer, poly(ethylene glycol) 300 (PEG).(More)
Simultaneous recordings were made of the spike activity of groups of 6–7 neurons in the putamen in two monkeys (Macaca nemestrina and Macaca mulatta) during performance of alternative spatial selection. Discriminant analysis was used to evaluate the magnitude of rearrangements in spike activity in groups of neurons during transitions from each step of the(More)
AIM To assess detection rate of parvovirus B19 markers in population of donors in one of the regions of Russian Federation. MATERIALS AND METHODS Screening of blood samples from 1000 donors for parvovirus B19 DNA was performed by real-time polymerase chain reaction. Levels of specific antibodies to parvovirus B19 were measured by quantitative enzyme(More)
Parkinson’s disease (PD) is the second most common severe neurodegenerative disorder that is characterized by progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc) region of the brain. However, causes and mechanisms of the development of this disorder are still not fully understood. At the same time, it is well known(More)
Spike activity in monkey striatum (putamen) neurons was recorded during the performance of a complex multistep operant task. Tonic responses propagating beyond a single action were recorded, along with phasic responses seen within a given action. The tonic type of response was recorded in 132 of 148 cells. Only 11 of these neurons showed exclusively this(More)
Microspheres were obtained on the basis of poly(3-oxibutyrate) (POB) with the inclusion of the Chlorambucil and Etoposide cytostatic drugs in a polymer matrix, and the morphology, kinetics of drug release from microspheres, and the interaction between microspheres and tumor cells in vitro were studied. Data on the kinetics of drug release suggests that a(More)
Experimental modeling of mental disorders on animal helps both to reveal mechanisms of the appearance of pathology and to direct the ways of effective methods of its treatment. The goal of the present work was to create a new model of schizophrenia by oral Levodopa+Carbidopa (LC) administration. Introduction of LC to rats was found to induces a significant(More)
The striate body or striatum is the largest subcortical nucleus, where efferent fibers from all regions of the brain cortex converge [1]. According to the results of numerous experiments, the striatum affects almost all brain functions. Therefore, its own functions are various. The striatum is considered to serve as a focus and filter of the cortical(More)
