Development Of Technological Sour-milk Desserts Enriched With Bifidobacteria

The work is devoted to the development of the technology of fermented sour-milk desserts, enriched with bifidobacteria and biologically active and physiologically valuable substances of fruit-berry raw materials. Bifidobacteria regulate the quality and quantity composition of the normal intestinal microfllora that is an important factor of organism protection from different intestinal infections. The healthy effect is mainly conditioned by biologically valuable properties of specially selected consortiums of lacto- and bifidobacteria, more stable for the effect of inhibitors and unfavorable environmental conditions.At the joint use of selected consortiums of strains of bifido- and lactobacteria, the number of viable cells of bifidobacteria increases in 3-4 times, the antagonistic activity increases comparing with using separate strains of microorganisms.The use of fructose and lactulose as a biostimulating component of sour-milk desserts raises the activity, growth and development of bifidobacteria. For stabilizing the structure of sour-milk clots, there were used hydrocalloids, such as pectin and starch that favors the increase of the number of viable cells of bifidobacteria, provides the necessary viscosity and certain humidity, prevents stratification at using fruit-berry prebiotics. The optimal storage term of sour-milk desserts at temperature (3±1) оС is no more than 15 days

Information structure development: Evidence from the acquisition of word order in Russian and English

The present paper aims at shedding some light onto the nature of the early child grammar. It is claimed that children do not operate with pure syntactic structures but also have access to pragmatics. On the basis of word order acquisition in Russian and English it is shown that from early on children resort to various strategies to encode information structure. Children acquiring Russian, a language that allows for structural encoding of Topic and Focus, make wide use of pragmatically marked word orders. Speakers of English, a highly configurational language, find other ways to mark information status of constituents, e.g. by means of Topic drop. The results of the study suggest that different grammatical modules, syntax and pragmatics in the particular case, are acquired in a parallel rather than consecutive fashion

The activity of isolated neurons and the modulatory state of an isolated nervous system represent a recent behavioural state

Behavioural/motivational state is known to influence nearly all aspects of physiology and behaviour. The cellular basis of behavioural state control is only partially understood. Our investigation, performed on the pond snail Lymnaea stagnalis whose nervous system is useful for work on completely isolated neurons, provided several results related to this problem. First, we demonstrated that the behavioural state can produce long-term changes in individual neurons that persist even after neuron isolation from the nervous system. Specifically, we found that pedal serotonergic neurons that control locomotion show higher activity and lower membrane potential after being isolated from the nervous systems of hungry animals. Second, we showed that the modulatory state (the chemical neuroactive microenvironment of the central ganglia) changes in accordance with the nutritional state of an animal and produces predicted changes in single isolated locomotor neurons. Third, we report that observed hunger-induced effects can be explained by the increased synthesis of serotonin in pedal serotonergic neurons, which has an impact on the electrical activity of isolated serotonergic neurons and the intensity of extrasynaptic serotonin release from the pedal ganglia
