The impact of secondary mineral formation on Na-K-geothermometer readings: a case study for the Valley of Geysers hydrothermal system (Kronotsky State Nature Biosphere Reserve, Kamchatka)

The temperature in the Valley of Geysers (Kamchatka) geothermal reservoir calculated using the feldspar Na-K-geothermometer has been steadily increasing over the past 10 years on average from 165 to 235 °C, which is close to the temperature values of a hydrothermal explosion of the steam and water mixture. For the analysis of chemical geothermometers, TOUGHREACT-simulation was used, with the help of which the previously known Na-K feldspar geothermometer was reproduced on a single-element model and new formulas were obtained for three Na-K geothermometers: zeolite, smectite, and based on volcanic glass. Data of chemical analysis for the period 1968-2018, in which the chloride ion is considered as an inert tracer of geofiltration processes, indicates that after 2007 a significant inflow of infiltration water (its mass fraction is estimated from 5 to 15 %) into the Geyser reservoir. It is assumed that the Na-K increased values of the feldspar geothermometer are not the result of the temperature increase in the Geyser reservoir, but the effect of smectite water dilution

Synthesis and Characterization of (Ca,Sr)[C2O4]∙nH2O Solid Solutions: Variations of Phase Composition, Crystal Morphologies and in Ionic Substitutions

To study strontium (Sr) incorporation into calcium oxalates (weddellite and whewellite), calcium-strontium oxalate solid solutions (Ca,Sr)[C2O4]∙nH2O (n = 1, 2) are synthesized and studied by a complex of methods: powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy. Two series of solid solutions, isomorphous (Ca,Sr)[C2O4]·(2.5 − x)H2O) (space group I4/m) and isodimorphous Ca[C2O4]·H2O(sp.gr. P21/c)–Sr[C2O4]·H2O(sp.gr. P 1 - ), are experimentally detected. The morphogenetic regularities of their crystallization are revealed. The factors controlling this process are discussed

Development of Micellar System for the Decontamination of Organophosphorus Compounds to Clean Technological Equipment

An analysis of composition of commercially available cleaning products, used in pharmaceutical enterprises today, was carried out, based on which it was found that they do not guarantee effective cleaning of equipment from organophosphorus compounds. It was concluded that the development of new composition of the cleaning agent, which effectively decontaminates organophosphorus compounds from surfaces of the equipment, is a pressing issue for ecologically safe manufacture of products containing substances of organophosphorus nature.A new system of micellar inactivation of active pharmaceutical ingredients of organophosphorus nature was developed. We conducted a study into the destruction of methylparathion by using the micellar system, which includes water, cetylpyridine chloride, hydrogen peroxide and boric acid. A concentration of cetylpyridine chloride, at which the largest constant of first-order reaction rate occurred, was established. It is shown that adding the activator, boric acid, increases the reaction rate by 2.5 times.Based on these studies, the composition of a model cleaning agent for cleaning technological equipment was proposed. An assessment of internal risks for quality of production stations when producing medicinal agent based on organophosphorus compounds in the form of eye drops was carried out. Production station was given the highest rating of internal risk – 3.We carried out an analysis of risks for cleaning reactor for preparing solutions RVD-630 in case of using the micellar system developed to decontaminate from residues of active pharmaceutical ingredients of organophosphorus nature.The obtained results might be used for devising the concept of validation of cleaning the reactor in the preparation of solutions. This is an important step in providing cleanliness of technological equipment under conditions of producing medicines based on organophosphorus compounds as active pharmaceutical ingredients at operating pharmaceutical enterprises

The Role of Insulin Resistance in the Development of Complications after Coronary Artery Bypass Grafting in Patients with Coronary Artery Disease

The aim of the study was to investigate the effect of carbohydrate metabolism disorders and insulin resistance indices on the immediate results of coronary artery bypass grafting (CABG). Method. Patients with coronary artery disease who underwent CABG (n = 383) were examined to determine glycemic status, free fatty acid and fasting insulin levels, and insulin resistance indices (Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), McAuley index, Quantitative Insulin Sensitivity Check Index (QUICKI), Revised-QUICKI). Patients were assessed for the development of perioperative complications and their length of stay in the hospital. Two groups were formed: group 1, patients with a combined endpoint (CEP, any complication and/or duration of hospital stay >10 days), n = 291; and group 2 (n = 92) without a CEP. Perioperative characteristics were analyzed, and predictors of hospital complications and prolonged hospital stay were evaluated. Results. Patients in the CEP group were older, and there were more women among them (p = 0.003). Additionally, in this group, there were more patients with diabetes mellitus (37.5% vs 17.4%, p p p = 0.007). In the group with a CEP, the levels of glucose (p = 0.031), glycated hemoglobin (p = 0.009), and free fatty acids (p = 0.007) and the Revised-QUICKI (p = 0.020) were higher than in the group without complications. In a regression analysis, the independent predictors of complications were combined operations (p = 0.016) and the predictors of a long hospital stay (>14 days) were female gender, the left atrium size, and diabetes mellitus (p p < 0.001). Conclusions: In the group with in-hospital complications after CABG, not only was the presence of diabetes mellitus more often detected, but there were also higher levels of free fatty acids and a higher Revised-QUICKI. Therefore, additional assessments of insulin resistance and free fatty acid levels are advisable in patients before CABG

Morphological and molecular evidence for synonymy of Corynosoma obtuscens Lincicome, 1943 with Corynosoma australe Johnston, 1937 (Acanthocephala: Polymorphidae)

Warner, LR ORCiD: 0000-0002-1587-8129Corynosoma obtuscens Lincicome, 1943 (Acanthocephala: Polymorphidae) is synonymised with Corynosoma australe Johnston, 1937 based on combined morphological and molecular evidence. Morphological comparison of C. obtuscens (24 males and 27 females) collected from a California sea lion Zalophus californianus (Lesson) in California, USA, with the type-specimens of C. obtuscens and C. australe, and with published data on C. australe collected from different hosts and regions showed no significant differences. The levels of genetic divergence in the cox1 sequences obtained from C. obtuscens from a California sea lion in the present study and C. australe from otariid seals from Argentina and penguins from Brazil ranged between 1.4–1.6% and was considered to represent intraspecific variability. Additionally, cox1 sequences were generated for Andracantha phalacrocoracis (Yamaguti, 1939), Corynosoma semerme (Forssell, 1904), C. strumosum (Rudolphi, 1802), C. validum Van Cleave, 1953 and C. villosum Van Cleave, 1953. Our results revealed inconsistency in the identification of material used as a source of the previously published sequence data for C. obtuscens and C. magdaleni Montreuil, 1958. © 2018, Springer Nature B.V

Expression of adipocytokines in heart fat depots depending on the degree of coronary artery atherosclerosis in patients with coronary artery disease.

In coronary artery disease (CAD) the adipocytokine content in the heart fat depot is altered, but it has not been established whether these changes are associated with the degree of atherosclerotic damage to the coronary artery (CA). Were examined 84 patients with CAD, and according to the degree of atherosclerotic state based on the SYNTAX Score scale, were divided: 39 moderate (≤22 points), 20 severe (23-31 points) and 25 extremely severe (≥32 points). Biopsies of subcutaneous (SAT), epicardial (EAT) and perivascular adipose tissue (PVAT) were obtained during elective coronary artery bypass grafting (CABG). The expression of adipocytokine was determined using real-time PCR. The concentration of the studied adipocytokines in adipocyte culture medium was measured by ELISA. Statistical analysis was performed using logistic regression analysis. In the adipocytes of the cardiac depot of patients with CAD, an increase in the expression and secretion of leptin and IL-6 and a decrease in adiponectin, with a maximum manifestation in severe and extremely severe CA lesions, was observed. EAT adipocytes were characterized by minimal expression of the adiponectin gene maximal gene expression leptin and IL-6 compared to SAT and PVAT adipocytes

Профессиональные факторы и роль индивидуальной восприимчивости к развитию и течению бронхолегочных заболеваний

Over the past decades, the world has seen an increase in occupational lung diseases, the leaders being asthma and chronic obstructive pulmonary disease (COPD). The article presents the results of 5-year observation of food industry workers. Clinical functional and molecular genetic studies have been carried out to identify the frequency and severity of asthma and COPD along with the individual predisposition to pulmonary conditions.Methods. 76 people of both sexes with the average age of 43.5 ± 3.6 years were examined on an outpatient basis. All subjects had daily contact with toxic and allergenic aerosols and organo-mineral dust. The respiratory function and the presence of bronchial hyperresponsiveness to occupational factors was assessed by spirography and peak flowmetry in response to exposure and elimination of industrial aerosols. Immunological and molecular genetic tests were performed: identification of hyposecretory alleles of the α1 -АТ gene, determination of polymorphisms of the GSTM1 and GSTT1 genes, immunoglobulin levels (IgE, IgM, IgG) and cytokine status (IL-4, -6, -8; TNF-α).Results. During the 5-year follow-up period, there was a significant increase in the number of employees with severe respiratory symptoms – 36.8% (95% CI – 21.2–36.8; p &lt; 0.05) and a statistically significant decrease in the respiratory function (p &lt; 0.001). Progressive decrease in the respiratory function in healthy individuals and the appearance of new and more severe cases of asthma and COPD were registered primarily among workers with hyposecretory alleles of the α1 -АТ gene and/or zero alleles of the glutathioneS-transferase genes (GSTM1 and GSTT1) in combination with abnormal cytokine status.Conclusion. Individual risk factors for the development of asthma and COPD in individuals working in contact with toxic and allergenic aerosols and organo-mineral dust are hyposecretory PiMZ variant of the α1 -АТ gene and deletions in the glutathione-S-transferase genes (GSTM1 0/0 and GSTT1 0/0) in combination with abnormal cytokine status. Long-term research results suggest the prognostic value of assessing individual sensitivity to industrial aerosols and the development of bronchopulmonary pathology.За последние десятилетия в мире отмечен рост профессиональных легочных заболеваний, среди которых ведущее место занимают бронхиальная астма (БА) и хроническая обструктивная болезнь легких (ХОБЛ). В статье представлены результаты 5-летнего наблюдения работников пищевой промышленности. Проведены клинико-функциональные и молекулярно-генетические исследования, при помощи которых выявлены частота и степень выраженности БА и ХОБЛ с определением индивидуальной предрасположенности к развитию легочной патологии.Материалы и методы. В амбулаторных условиях обследованы мужчины и женщины (n = 76; средний возраст – 43,5 ± 3,6 года), осуществлявшие повседневный контакт с токсикоаллергенными аэрозолями и пылью органоминерального состава. Проводилась оценка состояния функции внешнего дыхания (ФВД) и наличия гиперреактивности бронхов к профессиональным факторам методом спирографии и пикфлоуметрии в динамике экспозиции и элиминации производственных аэрозолей. Проведены иммунологические и молекулярно-генетические исследования – выявление гипосекреторных аллелей гена α1 -АТ, определение полиморфизмов генов GSTМ1 и GSTТ1, определение иммуноглобулинов (Ig)-E, -M, -G и цитокинового статуса (уровень интерлейкинов (IL)-4, -6, -8; фактора некроза опухоли-α).Результаты. За период 5-летнего наблюдения отмечен значимый рост (36,8 %) числа лиц с выраженными респираторными симптомами (95%-ный доверительный интервал – 21,2–36,8) и статистически достоверным снижением показателей вентиляционной функции легких (p &lt; 0,05; р &lt; 0,001). Прогрессирующее снижение показателей ФВД у практически здоровых лиц и появление новых случаев БА и ХОБЛ с ухудшением течения регистрировались в первую очередь среди лиц с гипосекреторными аллелями гена α1 -АТ и / или нулевыми аллелями генов глутатион-S-трансферазы (GSTM1 и GSTT1) в сочетании с нарушениями цитокинового статуса.Заключение. Индивидуальными факторами риска развития БА и ХОБЛ у лиц, работающих в контакте с токсикоаллергенными аэрозолями и органоминеральной пылью, являются наличие гипосекреторного PiMZ варианта гена α1 -АТ и делеция генов глутатион-S-трансферазы (GSTМ1 0/0 и GSTТ1 0/0) с нарушениями цитокинового статуса. По данным отдаленных результатов исследований указывается на прогностическое значение оценки индивидуальной чувствительности к производственным аэрозолям и развитию бронхолегочной патологии
