LOW-PROTEIN PASTA FOR CHILDREN PATIENTS WITH PHENYLKETONURIA

There are provided data on the work carried out at All-Russian Research Institute for Starch Products to create enriched low-protein pasta based on starch for nutrition the children sick with a phenilketonuria — a hereditary disease (group of fermentopatiya), the bound to violation of amino acids metabolism, mainly phenyl alanine. Optimization of children nutrition is the socially important direction of domestic policy of the Russian Federation since their health directly depends on the good balanced nutrition, especially it is important for the children having diseases of genetic character.To expand the range of the enriched low-protein food the functional ingredients are picked up, recipes and technology of receiving three types of pasta are developed such as: noodles, vermicelli, «spider line», their nutrition and power values are defined. It is shown that in the received products protein content doesn’t exceed permissible value (<1.0%), fat from 3.3 to 3.6%, ashes — to 0.14%, carbohydrates no more than 88.0% that conforms to requirements imposed to reduced-protein products of baby food.There are provided data on the work carried out at All-Russian Research Institute for Starch Products to create enriched low-protein pasta based on starch for nutrition the children sick with a phenilketonuria — a hereditary disease (group of fermentopatiya), the bound to violation of amino acids metabolism, mainly phenyl alanine.

Methodological aspects of the use of dry components of chicken eggs for feeding children with phenylketonuria

Currently, one of the most important tasks facing science and production is the creation of functional product technologies for use in different diets of the population in order to preserve and improve health, as well as reduce the risks and consequences of various diseases, including hereditary ones, such as phenylketonuria (PKU). The All-Russian Research Institute of Starch Products develops technologies for the production of low-protein starch-based products/semi-products enriched with functional ingredients and intended for therapeutic nutrition of patients with PKU. As part of the pilot production, the production of these products is organized. Purpose of work:to justify the possibility of using dry components of chicken eggs (melange, protein, yolk) to enrich low-protein starch products (noodles, vermichel, «spider») intended for feeding children over 3 years old with phenylketonuria;evaluate organoleptic properties and efficiency of low-protein starch products enriched in hypophenylalanine diet of patients with phenylketonuria older than 3 years

GENETIC FORMATION FACTORS OF DAIRY EFFICIENCY AND QUALITY OF CATTLE MILK

Experimental results of studying the efficiency of cattle selection method use on a genotype are presented to technologies of industrial milk production. For carrying out researches three groups of cows of the Ural black-andwhite breed type from lines Sovering Reflexion, Vis Back Ideal, Montwick Chiftain were created, up to 20 heads in every. The comparative analysis of dairy efficiency and quality of cow milk of different linear accessory is carried out. Impact of linear accessory of cows on a milk yield in 305 days of lactation, the content in milk of fat and protein, a ratio in milk protein of replaceable and irreplaceable amino acids is defined. It is revealed that the Ballele a kappa casein is characterized by the high content of protein in milk with the best abomasal coagulability. 14.3% of cows of the line Montwick Chiftain and 8% Sovering Reflexion had a desirable genotype on kappa casein - Centuries. Protein content in cow milk with a genotype of BB exceeded milk-protein indicators of cows of other genotypes by 0.14-0.18%. By amount of irreplaceable amino acids cow milk of the line Vis Back Ideal was the best that exceeded value of this indicator in cow milk of the line Montwick Chiftain and Sovering Reflexion by 9.5% and 4.5% respectively. It is established that in cow milk with AA genotype the share of irreplaceable amino acids exceeded their content as a part of the general protein in cow milk with a genotype of BB and AB for 8.9 and 39% respectively. Keywords: milk, kappa casein, milk fat and protein, selection, genotype, amino acids

Solid-state synthesis and characterization of ferromagnetic Mn5Ge3 nanoclusters in GeO/Mn thin films

Mn5Ge3 films are promising materials for spintronic applications due to their high spin polarization and a Curie temperature above room temperature. However, non-magnetic elements such as oxygen, carbon and nitrogen may unpredictably change the structural and magnetic properties of Mn5Ge3 films. Here, we use the solid-state reaction between Mn and GeO thin films to describe the synthesis and the structural and magnetic characterization of Mn5Ge3(Mn5Ge3Oy)-GeO2(GeOx) nanocomposite materials. Our results show that the synthesis of these nanocomposites starts at 180°С when the GeO decomposes into elemental germanium and oxygen and the resulting Ge atoms immediately migrate into the Mn layer to form ferromagnetic Mn5Ge3 nanoclusters. At the same time the oxygen atoms take part in the synthesis of GeOx and GeO2 oxides and also migrate into the Mn5Ge3 lattice to form Mn5Ge3Oy Nowotny nanoclusters. Magnetic analysis assumes the general nature of the Curie temperature increase in carbon-doped Mn5Ge3Cx and Mn5Ge3Oy films. Our findings prove that not only carbon, but oxygen may contribute to the increase of the saturation magnetization and Curie temperature of Mn5Ge3-based nanostructures

The study of the role of neurotransmitter systems in the pathogenesis of epilepsy is one of the priorities of epileptology. New data on the functions of free neurotransmitter-like amino acid in the central nervous system are of the greatest importance and determine the prospects for the development of novel effective anticonvulsants. It is widely believed in clinical medicine that epilepsy has distinct gender characteristics. The aim of this study was to investigate the gender peculiarities in the content of neurotransmitter amino acids in the brain of Krushinsky-Molodkina (KM) rats, which were used as model organisms for the study of genetically induced audiogenic epilepsy. The content of Asp, Glu, GABA, Gly, and Tau of the medulla oblongata, hippocampus and cerebral cortex were determined using high-performance liquid chromatography (HPLC) in intact KM rats, KM rats exposed to a series of epileptiform seizures, and Wistar rats (control group). Both the Wistar and KM rats had gender distinctions in the distribution of free amino acids among the investigated brain parts. The audiogenic epilepsy was characterized by smoothing gender differences as well as differences between the concentrations of free amino acids in the cortex and medulla oblongata, specific for Wistar rats. The changes observed in male rats after the set of seizures included the increase in GABA concentration and a decrease in the Gly level in all investigated brain parts, as well as the decrease of the Tau content in the cortex and hippocampus. At the same time, the Glu content in cortex increased, while the Asp level decreased. After 6 days of audiogenic stimulations the female KM rats demonstrated the increase in the Glu level in all investigated brain parts, the increase in Gly and Asp levels in hippocampus, and no changes in the GABA content. Thus, after the set of epileptiform seizures the KM rats achieved a new steady state of the studied amino acids pool, which differed in males and females. In this case, gender differences significantly changed after the seizures. © 2020 Russian Academy of Medical Sciences.

Autler - Townes doublet probed by strong field

This paper deals with the Autler - Townes doublet structure. Applied driving and probing laser fields can have arbitrary intensities. The explanation is given of the broadening of doublet components with the growth of probing field intensity, which was observed in experiment. The effects of Doppler averaging are discussed.Comment: 12 pages, RevTeX, 5 figures in 9 file
