Influence of components structure and composition of binary mixtures of organic compounds on toxicity towards Daphnia Magna

Simplex representation of molecular structure is employed for consensus QSAR analysis of toxicity towards Daphnia magna of sodium salts of α-alkoxycarbonylsulfuric acids, aliphatic n-alcohols, phenols and their binary mixtures. The structure of a mixture is represented both using descriptors of individual compounds included in the mixture and using novel specific mixture parameters termed unconnected simplexes. The studied dataset included 15 single compounds and 20 mixtures. The logarithm of EC50 (mmole/l) is used as a target function. Aims of the research are the determination of molecular fragments with positive or negative influence on the toxicity and developing QSAR models capable to predict properly the toxicity of new compounds and mixtures from their structure and composition. Successful consensus model based on forty best QSAR models (R2=0,86…0,97; Q2=0,74…0,96; R2test=0,86…0,99) is obtained using different training and test sets

Complex 99mTc-PDA-DTPA for myocardial imaging

The 123I-labeled fatty acids such as 123I-Iodophenylpentadecanoic acid and 123I-Beta-methyliodophenylpentadecanoic acid are the agents used clinically for myocardial imaging. Fatty acids are the major source of energy for the normal myocardium. However, under ischemic conditions the myocardial cells switch to glucose metabolism for their energy needs. Fatty acids undergo prolonged metabolic stunning in patients with reversible ischemia, thereby helping in early diagnosis of coronary artery disease in highrisk patients. High cost andlimited availability of cyclotron-produced 123I, makes 99mTc-labeled fatty acids more desirable for the purpose. In diagnosis the dominant radionuclide is 99mTc. It is estimated that it is involved in about 85% of all imaging procedures in nuclear medicine. The method for preparation of new 99mTc-fatty chemical systems based on modified diethylene triamine pentaacetic acid (DTPA) molecule has been elaborated in this work . The main advantage using DTPA as chelate agent for radioactive label, is the molecule or it's derivative ability to form sufficiently stable complexes with different radioactive metals including technetium-99. Moiety of pentadecanoic acid addition gave the ability to prepare modified complex of DTPA. In a labeling procedure, freshly eluted Na99mTcO4 (20mCi) was added to a mixture of cysteine, stannous chloride, PDK-DTPA and ethanol in a vial. On keeping the reaction mixture at 90 0C for 30 min, [99mTc-PDK-DTPA] radiopharmaceutical was formed. Thereafter, the reaction mixture was cooled over ice and characterized by HPLC. The result of dynamic scintigraphic research showed, that after being injected, the substance is actively acumulated into myocardium. Eventually one can say that modified DTPA-moleculs are functionally suitable for myocardial imaging

ВСЕРОССИЙСКИЙ ФИЗКУЛЬТУРНО-СПОРТИВНЫЙ КОМПЛЕКС «ГОТОВ К ТРУДУ И ОБОРОНЕ» КАК ОЦЕНОЧНОЕ СРЕДСТВО УРОВНЯ СФОРМИРОВАННОСТИ ПРОФЕССИОНАЛЬНЫХ КОМПЕТЕНЦИЙ СТУДЕНТОВ-МЕДИКОВ ПО ДИСЦИПЛИНЕ «ФИЗИЧЕСКАЯ КУЛЬТУРА»

The problem of estimation of students’ professional competence level in “Physical education” is a difficult task to solve. The RWD complex corresponds the demands of the modern pedagogical evaluation and is the universal means of formation of quantitative evaluation of competencies. Analysis of the results shown by students in certain types of tests indicates a relatively weak preparedness for passing the standards of the RWD complex. To create the most favorable conditions for the formation of competence in the discipline “Physical education”  during the development of the educational program it is necessary to include types of the RWD complex among credit requirements and evaluate them in accordance with the score-rating system.Проблема оценивания уровня сформированности компетенций по дисциплине «Физическая культура» у студентов-медиков является сложно решаемой задачей. Комплекс ГТО как оценочное средство соответствует требованиям современного педагогического оценивания и является универсальным количественным оценочным средством сформированности компетенций. Анализ результатов, показанных студентами при выполнении отдельных видов испытаний, свидетельствует о сравнительно слабой подготовленности к сдаче норм комплекса ГТО. Для создания наиболее благоприятных условий формирования компетенций по дисциплине «Физическая культура» при освоении образовательной программы необходимо виды испытаний комплекса ГТО включить в число зачетных требований и оценивать их в соответствии с балльно-рейтинговой системой

Comparison of quality of life in patients with primary postoperative and autoimmune hypothyreosis

Background. Achieving a high level of quality of life is one of the priorities in the treatment of chronic diseases. Focusing on the quality of life, it is possible to optimally adjust the treatment plan for patients, influencing the link that suffers most in this pathology. Hypothyroidism is mainly formed as a result of surgery on the thyroid gland, or autoimmune thyroiditis, and at the same time is one of the most common endocrine diseases, is of great social importance due to the potentially adverse effect on most organs and systems, resulting in a decrease in quality of life.The aim. To analyze the impact of primary hypothyroidism (postoperative hypothyroidism and autoimmune thyroiditis) on the quality of life of patients.Materials and methods. During the study, a clinical, laboratory and psychological study of 78 women with uncompensated primary hypothyroidism was carried out: 40 women aged 32–76 years with postoperative hypothyroidism (main group) and 38 women aged 36–60 years with autoimmune thyroiditis (comparison group). The quality of life was judged by the indicators of the MOS SF-36 questionnaire.Conclusion. In the examined patients with primary hypothyroidism, an association between an increase in TSH levels and a decrease in all indicators of the quality of life was revealed. First, indicators of physical functioning, general health, role and emotional functioning worsened. The dependence of indicators on the MOS SF-36 scales with the age of patients, the duration of hypothyroidism, and the level of TSH was revealed. The quality of life in patients with postoperative hypothyroidism was significantly reduced compared to patients who had hypothyroidism due to autoimmune thyroiditis

The use of {99m}Tc-Al[2]O[3] for detection of sentinel lymph nodes in cervical cancer patients

The purpose of the study was to evaluate the feasibility of using {99m}Tc-Al[2]O[3]- based radiopharmaceutical, a novel molecular imaging agent for sentinel lymph node detection in patients with invasive cervical cancer. The study included 23 cervical cancer patients (TlaNxMx- T[2]bNxMx) treated at the Tomsk Cancer Research Institute. At 18 hours before surgery, 80 MBq of the {99m}Tc-Al[2]O[3] were injected peritumorally, followed by single-photon emission computed tomography (SPECT) of the pelvis and intraoperative SLN identification. Twenty-seven SLNs were detected by SPECT, and 34 SLNs were identified by intraoperative gamma probe. The total number of identified SLNs per patient ranged from 1 to 3(the mean number of SLNs was 1.4 per patient). The most common site for SLN detection was the external iliac region (57.2%), followed by the internal iliac, obturator, presacral and retrosacral regions (they amounted to 14%, respectively),and the parametrial region (1%). Sensitivity in detecting SLNs was 100% for intraoperative SLN identification and 79% for SPECT image

Гельминтозоонозы диких хищных млекопитающих в Приморском крае Дальнего Востока РФ

The purpose of the research is to examine the helminthological status of wild carnivore mammals inhabiting the territory of the Primorsky Krai and to give an epidemiological assessment of their role in maintaining the natural foci of zoonotic infections.Materials and methods. Feces of carnivores were collected in natural habitats of wild animals. Species of animals were identified by the characteristic features of feces and animal tracks. The shape, size, texture and composition of feces were analyzed. The samples were placed in containers with 5% formalin. A part of the material was stored in native form at -12 ºС. Muscle tissue samples were obtained from animal carcasses. Feces were examined by flotation techniques with a solution of zinc sulfate, the formalin-ethyl acetate sedimentation technique and using an ammonium nitrate solution. After the study, the samples were disinfected by autoclaving at a pressure of 1.5 atm for 2 hours. Muscle tissue samples were examined by digesting in artificial gastric juice using the Gastros device. The species of Trichinella sp. larvae isolated from the positive samples were identified using the nucleotide sequences. In total, 444 feces samples from 13 species of wild carnivore mammals and 449 muscle tissue samples from 13 species were examined.Results and discussion. Wild carnivore mammals inhabiting the territory of the Russian Far East are often infected with various species of helminths localized in the intestine and tissues, which are causative agents of dangerous parasitic zoonoses. A total of 9 species of helminthes in the Siberian tiger (Panthera tigris altaica), 3 species in the Amur leopard (P. pardus orientalis), 2 species in the Eurasian lynx (Lynx lynx), 4 species in the leopard cat (Prionailurus bengalensis), 5 species in the sable (Martes zibellina), 2 species in the yellow-throated marten (M. flavigula), 5 species in the Siberian weasel (Mustela sibirica), 1 species in the American mink (Neovison vison), 2 species in the Asian badger (Meles leucurus), 8 species in the red fox (Vulpes vulpes), 2 species in the raccoon dog (Nyctereutes procyonoides), and 9 species in the brown bear and Asiatic black bear (Ursus arctos and U. thibetanus) were identified at studying of 444 feces samples of wild carnivore mammals in the Primorsky Krai. Among the detected helminths were highly pathogenic for humans: Toxocara cati, Paragonimus westermani and nematodes of the family Capillariidae. Trichinella sp. larvae were detected in 96 samples in the study of 449 samples of muscle tissue from wild carnivore mammals. The above types of helminths are of zoonotic nature. The pathogenic role of accidental infection with helminth species Baylisascaris transfuga has not yet been revealed in humans, that makes this type of bear ascaride potentially dangerous for humans. The studies have shown the widespread prevalence of helminth zoonoses in the Primorsky Krai. These data will help to organize properly the work of people whose jobs involve contact with wild animals.Цель исследований – изучить гельминтологический статус диких хищных млекопитающих, обитающих на территории Приморского края, и дать эпидемиологическую оценку их роли в поддержании природных очагов зоонозных инвазий.Материалы и методы. Фекалии хищных млекопитающих собирали в естественных биотопах диких животных. Видовую принадлежность фекалий определяли по характерным видовым признакам и следам животных. Анализировали форму, размер, консистенцию и состав фекалий. Пробы помещали в контейнеры с 5%-ным формалином. Часть материала хранили в нативном виде при –12 ºС. Образцы мышечной ткани получали от трупов животных. Фекалии исследовали флотационным методом с раствором сульфата цинка, методом этилацетат-формалинового осаждения и с использованием раствора аммиачной селитры. После исследования образцы материала обеззараживали автоклавированием в течение 2 ч при давлении 1,5 атм. Образцы мышечной ткани исследовали методом переваривания проб в искусственном желудочном соке с помощью аппарата Gastros. Вид личинок Trichinella sp., выделенных из положительных проб, определяли на основании нуклеотидных последовательностей. Всего происследовано 444 пробы фекалий 13 видов диких хищных млекопитающих и 449 проб мышечной ткани 13 видов.Результаты и обсуждение. Дикие хищные млекопитающие, обитающие на территории Дальнего Востока России, часто бывают заражены различными видами гельминтов кишечной и тканевой локализации, являющимися возбудителями опасных антропозоонозов. При исследовании 444 проб фекалий диких хищных млекопитающих в Приморском крае у амурского тигра (Panthera tigris altaica) выявлено 9 видов гельминтов, у амурского леопарда (P. Pardus orientalis) – 3, у евразийской рыси (Lynx lynx) – 2, у бенгальского кота (Prionailurus bengalensis) – 4, у соболя (Martes zibellina) – 5, у харзы (M. flavigula) – 2, у сибирского колонка (Mustela sibirica) – 5, у американской норки (Neovison vison) – 1, у азиатского барсука (Meles leucurus) – 2, у лисицы (Vulpes vulpes) – 8, у енотовидной собаки (Nyctereutes procyonoides) – 2 и у бурого и гималайского медведей (Ursus arctos, U. thibetanus) – 9 видов. Среди обнаруженных гельминтов были высоко патогенные для человека: Toxocara cati, Paragonimus westermani и нематоды сем. Сaрillariidae. При исследовании 449 проб мышечной ткани диких хищных млекопитающих в 96 выявлены личинки Trichinella sp. Вышеперечисленные виды гельминтов имеют зоонозную природу. Патогенная роль при случайном заражении гельминтами вида Baylisascaris transfuga на сегодняшний день у человека не изучена, что делает этот вид потенциально опасным для людей. Исследования свидетельствуют о широком распространении гельминтозоонозов на территории Приморского края. Полученные результаты помогут правильно организовать работу людей, чья профессиональная деятельность предусматривает контакты с дикими животными

Objective of research: studying of acute toxicity of supramolecular complexes of Fenbendazole developed using chemical mechanical technology in comparison with the substance of preparation injected to the stomach of white mice and rats. Materials and methods: The research of parameters of acute toxicity of the supramolecular complexes of Fenbendazole was conducted according to «Guidelines for experimental (pre-clinical) studies of new pharmaceutical compounds», and other rules. Preparations were injected to the stomach of white rats and mice of both gender with the body mass 160–180 and 18–20 g. at a single dose 7 000, 10 000, 15 000 and 20 000 mg/ kg, respectively. Each dose was investigated on 6 white rats and 10 white mice. Within 14 days we observed the general health status and behavior of animals, symptoms of intoxication and eventual death. We also conducted postmortem examinations of the fallen animals. The parameters of acute toxicity were determined by the method of Litchfield J. and Wilcoxon F. (M.D. Belen’ky, 1963). Results and discussion: It was not possible to detect LD50 in supramolecular complex of Fenbendazole and the base  drug Fenbendazole due to the low toxicity. The maximum endurable dose of supramolecular complex no. 2 was 10 000 mg/kg, LD50 -value in supramolecular complex of Fenbendazole no. 2 at injection to the stomach of white mice and rats was 20 000 mg/kg.Цель исследования – изучение острой токсичности супрамолекулярных комплексов фенбендазола, полученных по механохимической технологии в сравнении с субстанцией препарата при введении в желудок белым мышам и крысам. Материалы и методы. Изучение параметров острой токсичности супрамолекулярных комплексов с фенбендазолом проводили согласно «Руководству по экспериментальному (доклиническому) изучению новых фармакологических веществ» и других правил.
