Reinforced Epoxy Binder Modified with Borpolymer.

Polymer binders based on epoxy resins have unique properties that contribute to their use in many composite industries. The potential of using epoxy binders is due to their high elasticity and strength characteristics, thermal and chemical resistance, and resistance to climatic aging. This is the reason for the existing practical interest in modifying the composition of epoxy binders and understanding the strengthening mechanisms in order to form reinforced composite materials with a required set of properties based on them.

[The efficacy of tes-therapy for treatment of anxiety-like behavior and motor disorders in rats with an experimental model of parkinsonism].

Aim: To assess the efficacy of transcranial electrostimulation TES for treatmnet of anxiety-like behavior and motor disorders in rats with rotenone-induced parkinsonism.

Material And Methods: The study was performed on 30 mature male-rats. Animals were divided into following groups: control, intact rats (group 1); rats with an experimental model of parkinsonism without treatment (group 2); rats with an experimental model of parkinsonism, which had 7 sessions of TES-therapy (group 3), the number of rats in each group was 10.

[Conditions of cultivation, composition, and biological activity of mycelium of Flammulina velutipes (Fr.) P. Karst].

A study is made on a strain of higher basydiomycete Flammulia velutipes (Fr.) P. Karat.

[Natural autoantibodies against MP65 and ACBP14/18 and ontogenic formation of rat nervous system].

It was demonstrated that passive immunization of pregnant female rats against MP65 and ACBP14/18 proteins leads to stable changes in offspring behavior (deviations in acquisition of active avoidance in a shuttle-box and changes in the open-field behavior). Immunomorphological data about localization of MP65 and ACBP14/18 proteins in brain slices of adult rats and rat embryos are presented. The obtained results are discussed in terms of the influence of maternal humoral immunity on the formation of fetal nervous system during intrauterine development.

[Activity of exoglycans as sorbents of heavy metal ions].

The ability of yeast exoglycans (from Cryptococcus laurentii, Cr. luteolus, and Sporobolomyces albo-rubescens) to absorb copper and lead ions has been studied. The sorption isotherms have been obtained, which indicates that the mechanism of interactions in the system polysaccharide-metal is complex.
