Calculation model of the “building-foundation” system on anisotropic base and deformation calculations

In the construction of new buildings and facilities although the requirements of construction laws, building codes are observed, the heeling process and the collapse of the urban high-rise buildings are continuing at different speeds. Unfortunately, the number of such collapses and destruction in the world continues to this day. The purpose of this article is to show the mechanisms of collapse and patterns of deformation of loose and water-saturated soils of the construction site, which often have anisotropic structures by creating a calculated mechanical and mathematical model. A brief overview shows the state of the issue on the scale of the consequences of the collapse of modern high-rise buildings in the world. Attention is drawn to the lack of knowledge of the soil bases of structures of anisotropic structure. A computational model of a soil ground of complex anisotropic structure and algorithms for its application in practical calculations are proposed. The results of studies and their analysis, the regularities of the deformation state of the system consisting of foundation and buildings base, depending on the angle of inclination of the inclined layered base are developed in the study as well. In the form of tables and a large number of drawings there are the elucidated basic laws of inclination of buildings and structures that took place in large cities of Kazakhstan

Mosque Books of the Tobolsk Province of the 19th - Early 20^th Centuries as a Literary Text of the Siberian Tatars: Books Contents and Vocabulary

The question is raised about the study of mosque books of the Tobolsk province of the XIX - early XX centuries, stored in the State Budgetary Institution of the Tyumen region “State Archives of Tobolsk”. It is reported that the documents cover the period from 1830 to 1917 and are the metric books of the Siberian Tatars “on a note on births, about marriage, divorce and death”. The relevance of the study is due to the preservation and study of the literary texts of the indigenous Turkic people of Western Siberia - the Siberian Tatars. A review of the geography and chronology of preserved manuscripts is carried out, the features of the composition of the information contained in mosque books of the Sauskan and Chebourg yurts are considered. The authors emphasize the value of metric books as a source, since some traditional features of Tatar writing of the 18th-19th centuries have been preserved in them, which is associated with generally accepted standards for the design of official business papers. The scientific prospects of the study are considered: the creation of a written corpus of manuscript books of Siberian Tatars; analysis of the unexplored literary texts in the corpus, archaeographic (paleographic description, the study of graphics, spelling and punctuation), linguistic-textological and linguocultural aspects; application of the genealogical approach in describing the anthroponymic of Tobolsk province of the 19th - early 20th centuries on the basis of metric data on births, marriages, divorces and death

Bis(7-meth­oxy-1-methyl-4,9-dihydro-3H-β-carbolinium) tetra­chloridozincate

In the title compound, (C13H15N2O)2[ZnCl4], also known as di(harmalinium) tetra­chloridozincate, the ZnII atom is in a distorted tetrahedral coordination of the chlorido ligands. In the cation, the meth­oxy and methyl groups are both coplanar with with rings to which they are attached [maximum deviations of 0.232 (4) and 0.259 (4) Å, respectively]. In the crystal, the alkaloid cations and metal complex anions inter­act by way of N—H⋯Cl hydrogen bonds involving each Cl atom, resulting in a network structure

Bis(acetyl­acetonato-κ2 O,O′)(2-amino-1-methyl-1H-benzimidazole-κN 3)oxido­vanadium(IV)

The title mixed-ligand oxidovanadium(IV) compound, [VO(C5H7O2)2(C8H9N3)], contains a VIV atom in a distorted octahedral coordination, which is typical for such complexes. The vanadyl group and the N-heterocyclic ligand are cis to each other. The coordination bond is located at the endocyclic N atom of the benzimidazole ligand. Intra­molecular hydrogen bonds between the exo-NH2 group H atoms and acetyl­acetonate O atoms stabilize the crystal structure

Study of the Antitumor Activity of the Drug Dekoglitz on Two Tumors and Some Aspects of Its Mechanism of Action

Aim: Evaluation of the antitumor activity of the new drug Dekoglitz in animals with tumor strains of Sarcoma 45 in comparison with the drug dekocin, from which it was obtained, as well as with 5-fluorouracil and etoposide, and on ovarian tumors (OT) in comparison with the drug dekocin and identification of the effect of Dekoglitz on NA synthesis and internucleosomal DNA degradation. Methods: The study of preparations was carried out on 68 outbred rats with transplanted C-45 and OT tumors.The alkylating effect of the drugs was studied on cells tumor of Sarcoma 180. Results: The antitumor activity of dekoglitz on Sarcoma 45 was high, about 98/96%, with a remission rate of 80%. Its effect was 28-24% higher than that of dekocin. On OT, the effect of decoglitz with intraperitoneal administration reached 89/76% with a remission rate of 40%, with oral administration 96/86% with a remission rate of 60%. Conclusion:The study of the new drug Dekoglitz on animals with a tumor of Sarcoma 45 revealed its higher activity (by 20-27%) in comparison with the original Dekocin, 5-fluorouracil and etoposide with a lower level of side effects. On OT, the effect of Dekoglitz was 35-40% higher, especially after oral administration. Apparently, the great ability to suppress the synthesis of NA and carry out internucleosomal degradation and fragmentation of tumor DNA by the new drugs dekoglitz explains its antitumor efficacy,which is greater than that of Dekocin (K-18) in experiments on tumors

Mesenchymal stromal/stem cells and their exosomes for restoration of spermatogenesis in non-obstructive azoospermia: a systemic review

Stem cells have been introduced as new promising therapeutic agents in treatment of degenerative diseases because of having high differentiation potential while maintaining the ability to self-replicate and retaining features of their source cells. Among different type of cell therapies, mesenchymal stromal/stem cell (MSC) therapy is being increasingly developed as a new way to treat structural defects that need to be repaired and regenerated. Non-obstructive azoospermia (NOA) is a reproductive disease in men that causes infertility in 10% of infertile men. Based on in vitro studies, MSCs from different tissue sources have been differentiated into germ cells or gamete progenitor cells by simple methods in both male and female. On the other hand, the therapeutic effects of MSCs have been evaluated for the treatment of NOA animal models created by chemical or surgical compounds. The results of these studies confirmed successful allotransplantation or xenotransplantation of MSCs in the seminiferous tubules. As well, it has been reported that exosomes secreted by MSCs are able to induce the process of spermatogenesis in the testes of infertile animal models. Despite numerous advances in the treatment of reproductive diseases in men and women with the help of MSCs or their exosomes, no clinical trial has been terminated on the treatment of NOA. This systematic review attempts to investigate the possibility of MSC therapy for NOA in men

Percutaneous Pulmonary Valve Implantation in Small Conduits: A Multicenter Experience

BACKGROUND: Guidelines allow percutaneous pulmonary valve implantation (PPVI) in conduits above 16mm diameter. Balloon dilatation of a conduit to a diameter>110% of the original implant size is also not recommended. We analyzed patients undergoing PPVI in such conditions. METHODS AND RESULTS: Nine patients (May 2008-July 2016) from 8 institutions underwent PPVI in conduits 110%. Mean age and weight of the 14 patients was 12.1 (7.7 to 16) years and 44.9 (19 to 83) kg. Median conduit diameter at PPVI was 12 (10 to 17) mm. Median systolic right ventricular pressure was 70 (40 to 94) mmHg. Procedure was successful in all cases. A confined conduit rupture occurred in 7 patients (50%) and was treated with covered stent in 6. One patient experienced dislocation of 2 pulmonary artery stents that were parked distally. The post-implantation median systolic right ventricular pressure was 36 (28 to 51) mmHg. A fistula between right-ventricle outflow and aorta was found in one patient, secondary to undiagnosed conduit rupture. This was closed surgically. After a median follow-up of 20.16 (6.95 to 103.61) months, all the patients are asymptomatic with no significant RVOT stenosis. CONCLUSIONS: PPVI is feasible in small conduits but rate of ruptures is high. Although such ruptures remain contained and can be managed with covered stents in our experience, careful selection of patients and high level of expertise are necessary. More studies are needed to better assess the risk of PPVI in this population.info:eu-repo/semantics/publishedVersio

Влияние индексируемого объема левого предсердия на эффективность торакоскопического лечения фибрилляции предсердий

Research objective: establish the impact of Left Atrium Volume Index (LAVI) on on effectiveness of Thoracoscopic Ablation (TSA) in the Treatment of Atrial Fibrillation (AF) and define the risk factors for manifestation of supraventricular arrhythmias in the long-term follow-up resultsMethods. Prospective cohort study of 121 patients with AF (from 2018 to 2021) who performed TSA. The patients were divided into two groups: patients with increased LAVI (group I), patients with normal LAVI less than 34 ml/m2 (group II).Results. According to echocardiography, the mean LAVI was 45.48 ± 9.3 ml/m2 and 28.59 ± 4.13 ml/m2 in groups I and II, respectively (p = 0.012). The mean value of left ventricular ejection fraction (LVEF) according to Teicholz in group I was 61.62 ± 7.041%, in group II 63.57 ± 6.16% (p = 0.8). Spearman's сorrelation analysis showed the relationship between LAVI and LVEF before surgery and in the long-term follow-up period, that is agreed with world literature data about contribution left atrial (LA) to left ventricular (LV) function. According to our study, only LAVI < 34 ml/m2 is a risk factor for arrhythmia after TSA. Effectiveness TSA in I group was 77.8%, that is lower than the II group – 88.9%. 3 months after TSA, 20 (17%) patients were required catheter ablations (CA), mainly in I group.Conclusions. Research results showed that an increase in LAVI significantly reduces the effectiveness of TSA in the long-term period by 11.1% compared with LAVI < 34 ml/m2. That are conform with other data of previously submitted works.Цель исследования: установить влияние индексируемого объема левого предсердия (LAVI) на эффективность торакоскопической аблации фибрилляции предсердий (ФП) (ТА ФП) и определить факторы риска развития наджелудочковых нарушений ритма в отдаленном периоде наблюдения.Материал и методы. Проведено проспективное когортное исследование 121 больного с ФП (с 2018 по 2021 г.), которым была выполнена ТА ФП. Пациенты были разделены на две группы: в I группу были включены пациенты с увеличенным LAVI, во II группу – пациенты с нормальным LAVI менее 34 мл/м2.Результаты исследования. По данным эхокардиографии средний показатель LAVI составил 45,48 ± 9,3 мл/м2 и 28,59 ± 4,13 мл/м2 в I и II группах соответственно (p = 0,012). Среднее значение ФВ ЛЖ по Тейхольцу в I группе было 61,62 ± 7,041%, во II группе 63,57 ± 6,16% (p = 0,8). Корреляционный анализ по Спирмену показал взаимосвязь между LAVI и ФВ ЛЖ как до операции, так и в отдаленном периоде наблюдения, что согласуется с данными мировой литературы о вкладе ЛП в работу ЛЖ. Согласно нашему исследованию, только LAVI >34 мл/м2 является фактором риска развития аритмии после ТА ФП. В группе I эффективность ТА ФП составила 77,8%, что существенно ниже показателей восстановления синусового ритма по сравнению со II группой – 88,9%. Через 3 мес после операции потребовалось выполнение 20 (17%) дополнительных катетерных аблаций, преимущественно у пациентов I группы.Заключение. Данные нашего исследования показали, что увеличение LAVI достоверно снижает эффективность ТА ФП в отдаленном периоде на 11,1% по сравнению со II группой при LAVI < 34 мл/м2. Полученные результаты согласуются с данными ранее представленных работ
