Efficacy of cardiosynchronized electrical stimulation in patients with acute heart failure

Objective: to study the efficacy of external cardiosynchronized muscular counterpulsation (CMC) in patients with different variants of acute heart failure. The study included the examination results of 62 patients with acute heart failure, which undergo two variants (two groups) of therapy: 1) only the standard drug therapy (diuretics, nitrates, etc .) and 2) in the case of its inefficacy over 12 hours, combination of the drug therapy with the CMC sessions over 7 days. The clinical assessment of the patients under examination characterized the group with the standard therapy as less severe. In 64% of the group 2 patients, a significant improvement in the form of improvement in the fluid balance indices was noted during the combined therapy

Nuclear Polarization of Molecular Hydrogen Recombined on a Non-metallic Surface

The nuclear polarization of $\mathrm{H}_2$ molecules formed by recombination of nuclear polarized H atoms on the surface of a storage cell initially coated with a silicon-based polymer has been measured by using the longitudinal double-spin asymmetry in deep-inelastic positron-proton scattering. The molecules are found to have a substantial nuclear polarization, which is evidence that initially polarized atoms retain their nuclear polarization when absorbed on this type of surfac

Полинейромиопатия критических состояний (обзор литературы)

Neuromuscular disorders are extremely common in critically ill patients; they significantly affect the recovery time and limit the quality of subsequent  life. Until now, it is difficult to assess the presence of such disorders in intensive care units. The presented literature analysis of the current state of  the issues of epidemiology, pathogenesis and pathophysiology of critical illness polyneuromyopathy (CIPNM) determines the current directions  in the diagnosis and treatment of this pathology Нервно-мышечные расстройства чрезвычайно распространены у больных в критическом состоянии, они значительно влияют на сроки  выздоровления и ограничивают качество последующей жизни. До сих пор оценка наличия таких нарушений в отделениях реанимации  и интенсивной терапии представляет трудности. Представленный анализ литературы современного состояния вопросов эпидемиологии,  патогенеза и патофизиологии полинейромиопатии критических состояний (ПНМКС) определяет актуальные направления диагностики  и лечения этой патологии

The HERMES Polarized Hydrogen and Deuterium Gas Target in the HERA Electron Storage Ring

The HERMES hydrogen and deuterium nuclear-polarized gas targets have been in use since 1996 with the polarized electron beam of HERA at DESY to study the spin structure of the nucleon. Polarized atoms from a Stern-Gerlach Atomic Beam Source are injected into a storage cell internal to the HERA electron ring. Atoms diffusing from the center of the storage cell into a side tube are analyzed to determine the atomic fraction and the atomic polarizations. The atoms have a nuclear polarization, the axis of which is defined by an external magnetic holding field. The holding field was longitudinal during 1996-2000, and was changed to transverse in 2001. The design of the target is described, the method for analyzing the target polarization is outlined, and the performance of the target in the various running periods is presented

Substantiation of the Expediency to Use Iodine-enriched Soya Flour in the Production of Bread for Special Dietary Consumption

We have studied the possibility of using iodine-enriched soy flour in the process of making bread for people suffering from iodine deficiency, diabetes and celiac disease. The organoleptic, physical-and-chemical, and microbiological indicators have been investigated, as well as the content of toxic elements and iodine content in the developed soy flour. The rationally permissible formulation ratios have been proven experimentally. The quality indicators confirmed the possibility of using enriched soy flour in the process of making bread for special dietary consumption.The conducted complex of studies provides recommendations for technologists for production of bread with special dietary properties. That will make it possible to expand a range and to fill the market with products, which are in short supply now. A lack of the mentioned products is about 15 % of the total production of bakery products. We established that the iodine content is 50 μg per 100 g in the developed soy flour. The developed flour complies with the regulatory and technical documentation for food soy flour in terms of quality and safety. The rational dosage of the developed soy flour to green buckwheat flour is 10 % in new bread formulations. It will be rational to replace 15 % of buckwheat flour with 10 % of the developed soy flour and 5 % of carrot or beet powder in products with vegetable powders.The bread developed according to new formulations complies with DSTU 4588 for "Bakery products for special dietary consumption" in terms of organoleptic and physical-and-chemical parameters. The content of organically bound iodine is 48.9; 49.4; 50.0 mcg per 100 g 72 hours after baking in the bread made by the new formulations.Our study has made it possible to state that bread that is made according to the new formulations satisfies 1/3 % of the daily need for iodin

Persistent organic pollutants in the bottom sediments of estuaries of three rivers of Peter the great gulf (sea of Japan)

Методом хромато-масс-спектрометрии высокого разрешения исследовано содержание стойких органических загрязняющих веществ (СОЗ) в донных отложениях эстуарных зон трех рек бассейна залива Петра Великого (Японское море): Раздольная, Суходол и Гладкая. Показано, что по мере снижения содержания СОЗ располагаются в ряду ДДТ я ПХБ> ГХЦГ >ГХБ. Наибольшие их уровни обнаружены в донных отложениях реки Раздольная, где они в 1.5-27.7 раза выше экологически безопасных норм Канады (в России нормативы отсутствуют), составляя соответственно 44.7, 32.6, 2.2 и 0.75 мкг/кг сухой массы. В остальных исследованных реках содержание СОЗ было близко к фоновому уровню, отмеченному для центрально-европейской части России. Этот результат и данные о качественном составе каждой группы СОЗ свидетельствуют, что основной источник поступления полихлорированных бифенилов (ПХБ) в экосистему рек – глобальный трансграничный перенос, а для хлорорганических пестицидов (ХОП) возможно локальное поступление.Persistent organic pollutant (POP) contents in the bottom sediments of estuaries of three rivers (Razdol’naya, Sukhodol and Gladkaya) in the basin of Peter the Great Bay (Sea of Japan, Primorsky Territory, Russia) were studied using high resolution chromato-massspectrometry method. It is shown that POPs are ranged in accordance with decrease of their contents as follows DDTяPCBs>HCH>HCB. Their highest levels are revealed in the bottom sediments of Razdol’naya River where they are 44.7, 32.6, 2.2 и 0.75 яg/kg dry weight. That is 1.5-27.7 times above Canadian ecologically safety sediment quality guidelines for the protection of aquatic life. In Russian such guidelines are absent. In the bottom sediments of other rivers POP content was as low as a basic level for Central European part of Russia. These results and data on quality profile of POPs suggest that input of polychlorinated biphenyls (PCBs) to the rivers is global transboundary transfer while organochlorine pesticides (OCP) could enter from the local sources
