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

High-resolution ptychographic imaging at a seeded free-electron laser source using OAM beams

Electromagnetic waves possessing orbital angular momentum (OAM) are powerful tools for applications in optical communications, new quantum technologies and optical tweezers. Recently, they have attracted growing interest since they can be harnessed to detect peculiar helical dichroic effects in chiral molecular media and in magnetic nanostructures. In this work, we perform single-shot per position ptychography on a nanostructured object at a seeded free-electron laser, using extreme ultraviolet OAM beams of different topological charge order $\ell$ generated with spiral zone plates. By controlling $\ell$, we demonstrate how the structural features of OAM beam profile determine an improvement of about 30% in image resolution with respect to conventional Gaussian beam illumination. This result extends the capabilities of coherent diffraction imaging techniques, and paves the way for achieving time-resolved high-resolution (below 100 nm) microscopy on large area samples.Comment: M.

Diagnostics of Central and Autonomic Nervous System Dysfunction in Patients with Sepsis-Associated Encephalopathy

This chapter is devoted to monitoring of central and autonomic nervous system (ANS) in patients with verified sepsis to recognize the specific functional and anatomic changes in the brain and its important autonomic centers which is named sepsis-associated encephalopathy (SAE). Fluctuation of conscience level from agitation to delirium and coma, muscle tone, and severity of pain syndrome is evaluated with different scales (SOFA, SAPS II, RASS, CAM-ICU, FOUR, PBSS, BPS, MRC, MAS, CNS). Multimodal neuromonitoring includes EEG, EPs, ENMG, cerebral oxymetry, saturation in the bulb of the jugular vein, TCD, and neuroimaging (MRI, PET). Dysfunction of autonomic brainstem structures is detected with variational cardiointervalometry, pupillometry, thermometry (peripheral and central), photoplethysmography assessment of perfusion index, quantitative assessment of muscle strength on the MRC scale and MAS, and diagnostics of the severity of the PSH syndrome. Monitoring data help clinicians to make decisions on SAE patient management tactics

Risk factors for cardiovascular diseases in patients received complex treatment for cranial and craniospinal tumors in childhood

Aim. To study the traditional risk factors for cardiovascular disease (CVD), indicators of endothelial function and exercise tolerance in patients received complex treatment for cranial and craniospinal tumors in childhood, including radiation therapy.Material and methods. We compared examination data of 48 patients who underwent treatment for brain tumors using cranial and craniospinal irradiation in childhood (mean age, 21,7±4,3 years, mean period after the end of treatment, 6,9±5,4 years), and 20 healthy volunteers. Examination methods included assessment of lipid profile, vascular stiffness and endothelial function using the Photoplethysmography and occlusion test, cardiopulmonary test, and in patients who underwent craniospinal irradiation, also echocardiography and duplex ultrasound of extracranial arteries.Results. Compared to healthy individuals, patients after a brain tumor were found to have lower blood pressure, higher heart rate (HR), significantly lower exercise performance (peak oxygen consumption, 19,8±6,4 ml×min-1×kg vs 30,3±5,8 ml×min-1×kg, p<0,0001) and a higher prevalence of dyslipidemia (56% vs 5%, p<0,0001), as well as an increase in the augmentation index, indicating higher stiffness of large vessels (-7,3±16,3 vs -20,3±7,9, p=0,001), and a trend towards a decrease in the occlusion index (p=0,051). Echocardiography and duplex ultrasound revealed no radiation-associated abnormalities.Conclusion. Determining the mechanisms and prognostic significance of the identified risk factors for CVD (dyslipidemia, decreased exercise tolerance, increased heart rate and vascular stiffness) in this category of patients requires further research. Regular monitoring of risk factors, primarily the lipid profile, and the use of preventive measures for individuals with an increased risk of CVD should be recommended
