Thermoelectric power of nondegenerate Kane semiconductors under the conditions of mutual electron-phonon drag in a high electric field

The thermoelectric power of nondegenerate Kane semiconductors with due regard for the electron and phonon heating, and their thermal and mutual drags is investigated. The electron spectrum is taken in the Kane two-band form. It is shown that the nonparabolicity of electron spectrum significantly influences the magnitude of the thermoelectric power and leads to a change of its sign and dependence on the heating electric field. The field dependence of the thermoelectric power is determined analytically under various drag conditions.Comment: 25 pages, RevTex formatted, 3 table

The Fulde–Ferrell–Larkin–Ovchinnikov State in Pnictides

Fe-based superconductors (FeSC) exhibit all the properties of systems that allow the formation of a superconducting phase with oscillating order parameter, called the Fulde--Ferrell--Larkin--Ovchinnikov (FFLO) phase. By the analysis of the Cooper pair susceptibility in two-band FeSC, such systems are shown to support the existence of a FFLO phase, regardless of the exhibited order parameter symmetry. We also show the state with nonzero Cooper pair momentum, in superconducting FeSC with $\sim \cos(k_{x}) \cdot \cos (k_{y})$ symmetry, to be the ground state of the system in a certain parameter range.Comment: 8 pages, 4 figures Journal of Low Temperature Physics, (2013

Эффективность специализированной диетотерапии у пациентов с заболеваниями желудочно-кишечного тракта

Objective: to study the effectiveness of specialized diet therapy in patients with diseases of the gastrointestinal tract using 3 therapeutic and prophylactic food products (LLC «LEOVIT nutria»). Material and methods. The main group included 41 patients, who were divided into 3 subgroups depending on the type of therapeutic and prophylactic food products. The control group included 30 patients. The dynamics of the indicators of the clinical blood analysis and dynamics of indicators of metabolic disorders of liver function, including biosynthetic and secretory, were assessed (AST, ALT, GGT, total bilirubin). A study was also made of the dynamics of the spectrum of blood lipids by the content of total cholesterol, as well as the level of glucose in the blood on an empty stomach. All laboratory tests were carried out before the use of the products, on days 14 and 60 after the start of the use of therapeutic and prophylactic food products. Results. The studies noted good tolerance of products, the absence of allergic reactions or any side effects, even with prolonged use of specialized products (180 days). In the main group, plasma concentrations of AST, ALT and GGT, as well as total bilirubin decreased, while in the comparison group the differences were minimal. After 180 days in the main group ESR and CRP significantly decreased. The most significant decrease of these indicators (-54% and -207% respectively) was in the subgroup receiving «Vegetable Soup with Herbs and Oatmeal» (LEOVIT GASTRO). In the subgroup receiving «Oatmeal porridge with herbs and flax seed» (LEOVIT GASTRO) by 16 and 13%, and in the subgroup receiving «Protein-sea-buckthorn cocktail» by 34 and 266% of the initial level, respectively. Moreover, in the comparison group, changes in these indicators were statistically unreliable. In all subgroups of the main group, after 180 days, a statistically significant decrease in the concentration of glucose by 6-17% and cholesterol by 9-18% from the initial level occurred. Conclusions. The studied products have pronounced anti-inflammatory activity, have hypoglycemic and hypocholesterolemic effects, do not cause side effects, can be recommended for the general population for the prevention and treatment of gastrointestinal diseases.Цель исследования - изучить эффективность специализированной диетотерапии у пациентов с заболеваниями желудочно-кишечного тракта (ЖКТ) с применением трех лечебно-профилактических продуктов питания (ООО «ЛЕОВИТ нутрио»). Материалы и методы. Основную группу исследования составил 41 пациент, которые, в зависимости от вида получаемого лечебно-профилактического продукта питания, были дополнительно разделены на 3 подгруппы. Контрольную группу составили 30 пациентов. 141 Была проведена оценка динамики показателей клинического анализа крови и показателей метаболических нарушений функции печени, включая биосинтетические и секреторные (активность АСТ, АЛТ, ГГТ, общий билирубин). Также в исследовании изучалась динамика спектра липидов крови по содержанию общего холестерина и уровня глюкозы в крови натощак. Все лабораторные исследования проводились до начала применения продуктов, на 14-й и 180-й дни после начала применения лечебно-профилактических продуктов питания. Результаты. Отмечена хорошая переносимость, отсутствие аллергических реакций или каких-либо побочных эффектов даже при длительном применении специализированных продуктов (180 дней). В основной группе наблюдалось снижение концентрации в плазме крови АСТ, АЛТ и ГГТ, а также общего билирубина, при этом в группе сравнения различия были минимальны. Через 180 дней в основной группе отмечалось достоверное снижение СОЭ и концентрации СРБ относительно исходного уровня; наиболее выраженным это снижение было в подгруппе пациентов, получавших специализированный продукт диетического лечебного и диетического профилактического питания «Суп-пюре овощной с травами и овсянкой» (ЛЕОВИТ GASTRO) - на 54 и 207%, соответственно. В подгруппе, получавшей «Кашу овсяную с травами и семенем льна» (ЛЕОВИТ GASTRO), СОЭ и концентрация СРБ снизились на 16 и 13% от исходного уровня, соответственно, а в подгруппе, получавшей «Коктейль белково-облепиховый» (ЛЕОВИТ GASTRO) - на 34 и 266%. При этом в группе сравнения изменения этих показателей не имели статистической достоверности. Во всех подгруппах основной группы через 180 дней произошло статистически достоверное снижение концентрации глюкозы на 6-17% и холестерина на 9-18% от исходного уровня. Заключение. Исследованные продукты обладают выраженной противовоспалительной активностью, оказывают гипогликемический и гипохолестеринемический эффекты, не вызывают побочных эффектов и могут быть рекомендованы широкому кругу пациентов с целью профилактики и комплексной терапии заболеваний ЖКТ

Experience of application of specialized food product of dietary therapeutic and dietary preventive nutrition in case of inflammatory diseases of gastrointestinal tract

Introduction. In almost all diseases of the gastrointestinal tract, the inflammatory process plays an important pathogenetic role and affects the course of the disease and the determination of treatment tactics. The most physiological way to prevent and treat inflammatory diseases of the gastrointestinal tract, of course, is dietary nutrition. Purpose: To study the anti-inflammatory effect of a specialized product specialized therapeutic and dietary prophylaxis nutrition «Vegetable soup with oatmeal herbs» based on a study of clinical and laboratory parameters and dynamics of inflammatory markers. Materials and methods. An open single-center prospective observational study was conducted in parallel groups. The main group and the comparison group were 14 and 10 patients with gastrointestinal diseases, respectively. Only patients of the main group received a specialized product «Vegetable Soup with herbs and oatmeal». All participants were assessed the dynamics of clinical blood analysis indicators (hemoglobin, white blood cells, red blood cells, leukocyte formula indicators) and the dynamics of proteinogram indicators (total protein and protein fractions-albumins and globulins) and C-reactive protein (CRP). Results. The anti-inflammatory effect after administration of the specialized product occurs in 14 days and is expressed in a reliable reduction of leukocytosis, blood sedimentation rate (BSR), CRP. After 2 months after the start of the product intake, the BSR values decreased significantly by 35%, the CRP by 51% from the baseline and the leukocyte content decreased by 14.5%. Against the background of a dietotherapy in 14 days levels α1-глобулина, α2-глобулина and γ-globulin began to decrease, and in 2 months level α1-globulins decreased by 40% of initial level to the reference values. The level of α2-globulins and γ-globulin also decreased significantly, while the albumin concentration in the blood increased significantly. In the comparison group, changes in these parameters did not reach a reliable degree of significance. Conclusions: the specialized product «Vegetable Soup with herbs and oatmeal» has an anti-inflammatory effect, characterized by a decrease in anti-inflammatory laboratory parameters, which manifests itself after 14 days of administration, can be recommended for inclusion in the diets of patients with gastrointestinal diseases during exacerbation and during remissions as well. © 2020, Remedium Group Ltd.
