The conditions of isovalent substitution of Nd atoms for Sm atoms in A-positions of the BaNd2In2O7 two-slab perovskite-like structure of the BaNd2-xSmxIn2O7 type (0 £ x £ 1.8) have determined by X-ray powder diffraction methods. Tetragonal crystal structure (space group P42/mnm) of the BaNd2-xSmxIn2O7 phases with substitution degree of Nd atoms equal to 0.5, 1.0, 1.5 and 1.8 was determined by the Rietveld method. Crystal structure of BaNd2-xSmxIn2O7 is based on the two-dimensional (infinite in the XY plane) perovskite-like blocks, consisting of two slabs of the deformed InO6 octahedra connected by vertices. Ba atoms are localized only at 4f position inside the perovskite block, while REE atoms are placed only at 8j position at the boundary of the perovskite block. The adjacent perovskite-like blocks are separated by a slab of LnO9 polyhedra and held together by - O - Ln - O - interblock bonds. It is established that the isovalent substitution of Nd atoms by smaller Sm atoms leads to a decrease in the length of the Ln - O2 distance (from 0.230(2) nm to 0.206(2) nm) and to an increase in the degree of deformation of the interblocks of LnO9 polyhedra, the inner block polyhedra BaO12, and the InO6 octahedra as well. Such structural changes destabilize the interblock "stitching" and are one of the main destruction factors of the slab perovskite-like structure of the BaNd2-xSmxIn2O7 phases at x > 1.8. Data obtained could be used for directed regulation of structure-sensitive properties of materials based on the BaNd2In2O7 indate.

Ultrafine NiFe2O4 (T0) and NiFe2O4 / rGO composites have been synthesized by solution combustion method. The presence of rGO in the composite (33 wt.% (T1) or 66 wt.% (T2)) causes a decrease in the average particle size of the oxide phase from 16 to 10-11 nm with their transition to superparamagnetic with a decrease in the mixed spinel inversion degree. The SBET values for T1 and T2 are 180 and 315 m2/g, respectively, decreasing to 78 and 169 m2/g after annealing in the temperature range of 200-800°C. Both micro- and small mesopores (size of 2.0-4.5 nm) have been observed for samples T2, while samples T0 and T1 are mainly mesopores. The small polaron mechanism of electrical conductivity is observed for pure spinel, when the electron hopping charge transport prevails for NiFe2O4 / rGO composites. It can be assumed that the GO com­po­nent lowers the combustion reaction temperature and prevents particle agglomeration.

BACKGROUND: The potential relationship between pulmonary tuberculosis and lung cancer has been the subject of intense interest over the past few decades. Nevertheless, the features of the pathogenesis of concomitant pathology remain poorly studied.
AIM: The ain of the study to develop an experimental model of the concomitant pathology of tuberculosis and lung cancer.
MATERIALS AND METHODS: The study was performed on mice of the C57BL/6 line at the age of two months in four groups: 1st intact mice (n = 12), 2nd mice without a tumor infected with tuberculosis (n = 24), 3rd tumor-bearing mice not infected with tuberculosis (n = 23), 4th tumor-bearing mice infected with tuberculosis (n = 24). Individual and group parameters were evaluated using the SPSS Statistica v23 software package.
RESULTS: Tumor was developed at the site of primary transplantation in all mice from groups 3 and 4, which was confirmed by visual assessment and the results of histological examination. Tumor growth in the main group was significantly less than in the control group of the tumor, which may be due to intoxication against the background of tuberculosis infection. All infected mice from groups 2 and 4 developed pulmonary tuberculosis, confirmed by computed tomography of the lungs, bacteriological and histological examination of lung samples. Mycobacterial load in the lungs was the highest in animals with concomitant pathology of tuberculosis and tumor. The survival rate of mice was determined to a large extent by tumor growth rather than by the progression of tuberculosis infection.
CONCLUSIONS: The results of the study indicate the possibility of creating an experimental biological model of the concomitant pathology of tuberculosis and lung cancer in mice. The features of the course of the concomitant pathology were revealed: Lewis lung epidermoid carcinoma develops more slowly in tuberculosis infected animals than in the tumor control group; the development of the tuberculosis process in mice with a tumor occurs more intensively than in the tuberculosis infection control group. The survival rate of mice with concomitant pathology is determined more by the intensity of tumor growth than by the progression of tuberculosis.
Endometriosis and adenomyosis: common and disparate features

Published: December 2022

Endometriosis and adenomyosis are diseases of the gynecological profile, which are ectopic endometrioid tissue and have long been considered tangible manifestations of the process. Only recently have scientists begun to put forward a theory about the unequal origin of these pathologies. In endometriosis, the lining of the uterus extends beyond it, mainly to the ovaries, fallopian tubes, and bladder. With adenomyosis, the nodes grow into the muscular wall of her uterus and thicken. They do not go outside the uterus. Both conditions cause severe pain due to local inflammation, swelling and adhesions in the abdominal cavity. The only reliable way to identify the diagnosis of endometriosis is invasive exploratory laparoscopy with biopsy of tissue samples. In contrast, an enlarged uterus with adenomyotic nodules can be assessed even on routine examination, and on ultrasound or MRI they are visualized in the report. Obviously, despite the high frequency of pathophysiological and molecular mechanisms, endometriosis and adenomyosis has rare causes, clinics and effects on the reproductive system of the female body, which significantly reduces the risk and treatment of diseases.
The review provides a comparative characteristic of endometriosis and adenomyosis in terms of prevalence, etiology, pathogenesis, clinical manifestations, effects on fertility and experimental modeling, obtained from domestic and foreign sources.
Understanding the pathophysiology of adenomyosis and endometriosis opens up additional possibilities for diagnosis, prevention, and treatment. The development of new diagnostic methods based on modern high-tech methods allows us to assume a preclinical stage and identify the diagnosis, predict and carry out adequate treatment depending on the histological picture.

Рассмотрены особенности развития туристских дестинаций с точки зрения соблюдения принципов устойчивого развития. Отмечено, что в современных санкционных условиях основным видом туризма в Российской Федерации является внутренний туризм. Обеспечение устойчивого развития российских дестинаций в настоящее время возможно за счет увеличения внутренних туристских потоков и их равномерного распредения во временном аспекте. Показано, что активизация регионального событийного туризма позволит обеспечить устойчивое развитие туризма в рамках принимающей дестинации и за счет нивелирования эффекта сезонности в туризме.
The features of the development of tourist destinations from the point of view of compliance with the principles of sustainable development are considered. It is noted that in the current sanctions conditions, the main type of tourism in the Russian Federation is domestic tourism. Ensuring the sustainability of the development of Russian destinations is currently possible by increasing domestic tourist flows and their even distribution in time. It is shown that the activation of regional event tourism will ensure the sustainability of tourism development within the host destination and by leveling the effect of seasonality in tourism.

Published: December 2022

This study aims to test the reliability and validity of the Academic Resilience Inventory (ARI), which was developed by Samuel (2004) for the Indonesian context. The inventory adaptation procedure that the researchers did in this research refers to the journal Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures (Beaton, 2000). The total amount of sample used in this study was 200 students of Public Vocational School 1 Pandeglang, taken by using accidental sampling. To test the validity of the measurement inventory, the researcher used Confirmatory Factor Analysis (CFA) with Lisrel software. The result revealed that, in general, the Academic Resilience Inventory (ARI) by Samuel (2004) is significantly unidimensional, meaning it only measures the construct of the academic resilience inventory. However, in the result of CFA, the validity test known that item no.8 on the intelligence factor, item no. Forty on temperamental factors, items no. 2, 14, 25, 26, and 28 on social relations factors, item no. Three on the factor of family relations, item no. 6 on academic factors are invalid. Further psychometric properties analysis and education are described.

Glioblastoma (GBM) is the most common and aggressive primary malignant brain tumor with poor prognosis and high potential of dispersion to other brain tissues in adult. Effective and modern choices of treatment including chemotherapy with alkylating agents marginally extend survival of GBM. However, alkylating agents can lead to highly harmful mismatch during DNA replication causing apoptosis and cell death. Accordingly, O6-Methylguanine-DNA methyltransferase (MGMT) removes alkyl adducts, thereby causing resistance to alkylating drugs. Single-Nucleotide Polymorphisms (SNPs) in MGMT promoter region may play a role in the regulation of MGMT expression and prediction of glioma development risk. In order to evaluate the clinical significance of rs1625649 SNP in the MGMT promoter region of glioblastoma, genomic DNA from a series of 54 patients with GBM and 50 healthy individuals in Iranian population were collected for tetra ARMS PCR amplification. None of the "A" or "C" alleles were associated with tumor occurrence, the "AA" genotype was more frequent in healthy subjects, and the "AC" genotype was 4.6 times more common in patients with GBM. The longest survival time was observed in the "CC" genotype; however, this difference was not statistically significant. On the other hand, homozygous rs1625649 (AA genotype) was significantly associated with a better survival than the cases with heterozygous rs1625649 (CA genotype) or wild type rs1625649 (CC genotype), predicting better response to temozolomide-based chemotherapy.

Aim: Ischemia/reperfusion (I/R) injury is a common complication after abdominal aortic surgery. N-Methyl D-Aspartate (NMDA) antagonists protect many organs against to I/R injury. Therefore, in this study, we aimed to investigate the effects of 135 mg/kg and 90 mg/kg of amantadine, on lung tissue after lower extremity I/R injury in rats.
Material and Methods: 36 wistar rats were randomly divided into 6 groups each containing six rats as follows; Sham group (Group S), Amantadine 90 group (Group A-90), Amantadine 135 group (Group A-135), Ischemia/Reperfusion group (Group I/R), Ischemia/Reperfusion + Amantadine 90 group (Group I/R-A 90), Ischemia/Reperfusion + Amantadine 135 group (Group I/R-A 135). At the end of procedure, all rats were sacrificed, and their lung tissues were obtained. Lung tissues were examined biochemical and histopathologically.
Results: The lung tissue catalase, superoxide dismutase activities and malondialdehide levels were similar between the groups. Lung tissue neutrophil/lymphocyte infiltration score levels were higher in Group I/R than Group S, Group A-90 and Group A-135. Alveolar wall thickening score levels were higher in Group I/R than Group S, Group A-90, Group A-135 and Group I/R-A 135.
Conclusion: Although we could not find a statistically significant difference between lung tissue biochemical values, we observed that lung tissue was histopathologically affected by I/R damage and the damage was less with amantadine use. In the reduction of I/R damage, 135 mg/kg administration of amantadine was more beneficial than 90 mg/kg.

Актуальность исследования обусловлена возрастанием потребления нефтепродуктов и увеличением количества нефтяных отходов и остатков, в составе которых могут содержаться значительные количества высокомолекулярных гетеросодержащих компонентов асфальтенов и смолы. Стоит отметить, что асфальтены слабо подвержены биоразложению. Традиционно во многих странах способом утилизации нефтесодержащих отходов является способ их захоронения, но такой способ утилизации нежелателен, так как требует использования новых земельных участков и в конечном счете может нанести вред окружающей среде. В связи с этим возникла необходимость в поиске нового способа утилизации нефтяных отходов с возможностью получения из них ценных продуктов, которые могут быть применены в различных областях промышленности и хозяйственной деятельности, что в конечном итоге увеличит глубину переработки нефти. Цель: синтез углеродных графитоподобных наноматериалов методом плазменной переработки асфальтенов с получением потенциально полезной смеси газов, содержащей водород и метан. Объекты: высокомолекулярная фракция асфальтенов, выделенных экстракцией горячим ацетоном из природного асфальтита. Методы: плазменная переработка, рентгенофазовый анализ, растровая и просвечивающая электронная микроскопия, спектроскопия комбинационного рассеяния. Результаты. Представлены результаты экспериментальных исследований, посвященных плазменной переработке асфальтенов (основных компонентов тяжелых и остаточных нефтей большинства нефтяных отходов), совмещенной с процессом получения углеродных графитоподобных микро- и наноструктур. В ходе плазменной переработки формируется углеродный материал со структурой графита. По данным просвечивающей электронной микроскопии в продуктах синтеза идентифицированы три основные наноразмерные морфологические типа: углеродные нанотрубки, полиэдрический графит и луковичные структуры. Таким образом, работа вносит вклад в развитие технологий декарбонизации в жизненном цикле углеводородных отходов и технологий получения углеродных наноматериалов.
