The goals of this prospective observational study were to identify quantitative morphological factors that might aid in the prediction of PBMV outcome, as well as to define the function of 3D TEE in mitral valve evaluation. Material and Methods: The trial comprised seventy individuals who had isolated severe rheumatic Mitral Stenosis (MS) who were scheduled for PBMV between October 2017 and March 2021. Trans-thoracic echocardiography (TTE) was used for pre-procedural evaluation. Posterior to Anterior Leaflet Length Ratio (P/ALLR), Commissural Area Ratio (CAR), Doming Height (DH), and Calcification Score (Ca score) were also assessed using 2D and 3D-Trans-esophageal Echocardiography (TEE). Following that, all patients were monitored for three months. Results: We have had 50(71.5%) successful procedures and 20(28.5%) unsuccessful procedures. The additional parameters showed highly significant difference between successful and un-successful groups (P-value 0.6 and >0.55 by 2-D and 3-D TEE respectively, CAR ≤ 1.28 and ≤ 1.25 by 2-D and 3-D TEE respectively, DH > 1.2 cm by 2-D TEE, and Ca Score ≤ 2. Conclusion: In our research, we discovered that these characteristics may predict the result of PBMV and contribute value to the semi-quantitative methodologies we adopted to use.

This paper aims to comprehend the change & impact on students’ behavior during the COVID-19 Lockdown in India. The research is conducted by surveying to assess the different behavioral changes due to the COVID-19 spread. Novel coronavirus pandemic started from Wuhan, China, on 31/12/19. It spread across the globe affecting 1,00 000 people within the span of two to three months. People across the globe were affected not just in terms of physical health but also mental & psychological health, resulting in major changes in their behavior. The digital questionnaire assessed the status of pupils’ mental and psychical nature while the COVID-19 lockdown was on. The questions were framed to answer how students felt about the pandemic and how it has affected their day-today life. The results of the survey revealed the measure of the anxiety level of the students. The survey results are analyzed on SPSS, and Pearson Coefficient is the method used for statistical analysis. The survey results revealed that 74.2% of the respondents favored cleaning their hands more often due to the COCID-19 pandemic. In the same way, an overwhelming number of student respondents have become aware that wearing masks is crucial to prevent the spread, and 95.9% of student respondents have favored wearing masks if they decide to step outside of their house. Student respondents are more worried about the possibility that their family members will catch the COVID-19 virus than the concern of themselves catching the virus. The student respondents showed clear signs of worry and unpredictability due to the COVID-19 spread. More than have 37.6% have responded that they are in a constant state of worry during the lockdown. The paper states varied responses from the students on the anxiety levels and that they have been experiencing high anxiety levels during the lockdown. The measurement and correlation between emotional & preventive behavior can provide viable options to reduce the outbreak and further control it.

Implementation of the principles of activation electromagnetotherapy in experimental oncology
Статья
Introduction. Identification of an important mechanism of homeostasis associated with the existence of a periodic system of general nonspecific adaptational reactions of the body (AR) [1-3] as well as the study of the conditions for the development of the anti-stress AR of high levels of reactivity as the most favorable AR for an organism, allowed determining the requirements for the parameters of external regulatory actions, acting factors and regimes of their application. As a result, the principles of activation therapy (AT) were formulated: it is a treatment technology aimed at the physiological mobilization of the mechanisms of general nonspecific (including antitumor) resistance of the body. Among the AT factors, one of the leading places is occupied by electromagnetic radiation (EMR), which has a wave nature, to which the CNS structures as well as regulatory and metabolic processes of lower levels are highly sensitive [1, 3].

The aim of our research work was to study the level of sex steroids in blood, the tumor and the perifocal zone in rats of both sexes with Guerin’s carcinoma against the background of hypothyroidism. Materials and methods. The experiment was performed in 110 outbred rats of both sexes. Hypothyroidism was induced in animals for 30 days with Mercazolil medication, and then Guerin’s carcinoma was transplanted (the main group). The reference groups included animals with an independent growth of Guerin’s carcinoma and with independent hypothyroidism, as well as intact animals (the norm). On the 18th day of the tumor growth, the animals were sacrificed, and, using standard RIA kits, in the serum, the tumor homogenates and the perifocal zone, the levels of estradiol (E2), testosterone (T) and progesterone (P4) were determined. Results. In comparison with intact animals, hypothyroidism caused an increase in the blood content of E2 in animals of both sexes by 2.2-2.4 times and T by 1.4-16 times, and P4 by 1.7 times only in females, but recorded was a decrease therein in males by 2.4 times. The growth of Guerin’s carcinoma resulted in a 2.5-5.5-fold decrease in E2 in blood of the animals of both sexes, an increase in T by 2.1 times and P4 by 3 times in the females, but a decrease in T by 2.6 times without changing P4 in the males. In the main group, in the animals of both sexes, similarly to the processes in hypothyroidism, the level of E2 and P4 increased by 1.4-1.6 times, and in females also T by 4.4 times, compared with the intact animals. Conclusion. Hypothyroidism and the growth of Guerin’s carcinoma changed E2 in different directions in animals of both sexes the level of sex hormones in blood and shifted the steroid balance in the tumor and its perifocal zone. In the females of the main group, the saturation of the tumor with estrogens, androgens and progesterone decreased, while in the males, on the contrary, the concentration of steroids increased.

To study the intensity of lipid peroxidation (LPO) and the activity of the main antioxidant protection enzyme: superoxide dismutase (SOD) in heart tissues and tumors in rats of both genders with Guerin's carcinoma (GC) and the tumor growth against the background of diabetes mellitus (DM). Materials and methods. Our research work was carried out in 80 outbread albino male and female rats, divided into 4 groups, with 10 animals of each gender in a group. The animals of two groups, namely, an intact animal group and a group of rats treated with alloxan DM (with a 5-fold increase in glucose levels) were subcutaneously transplanted with the Guerin's carcinoma (GC) strain cells, and at the same time we used one group of the intact rats and another group of the animals with DM as the references. The content of malondialdehyde (MDA), diene conjugates (DC), and the SOD activity in the heart and the tumor tissues were determined by conventional spectrophotometric methods. Results. The most pronounced changes were found in the heart in the female rats with isolated GC and GC growing against the background of DM: a more than threefold increase in MDA, with a significant increase in DC and a multiple increase in the SOD activity as compared with the intact animals. In the GC tissue, the dependence of the severity of the increase in the MDA content on the size of the tumor was traced: the maximum increase in both parameters was observed in males with GC tumor growing against the background of DM. In the males, the volume of the subcutaneous tumor nodes was 1.8 times greater than that in the reference group and in the females with combined pathology, while in the females with combined pathology the volume of their tumors was 1.3 times less than that in the reference group, although the area of tumor lesions in them was maximum due to extensive metastasizing. Conclusion. DM has changed the specifics of oncogenesis depending on the gender of the animals. The identified gender differences in the redox status of the heart and the tumor in rats with combined pathology contribute to specifics of oncogenesis in males and females and determines their life expectancy.

The aim is to study the content of prekallikrein, kallikreins 1 and 14 (KLK-1 and KLK-14) in mice under the conditions of activation and inhibition of the B16/F10 inoculated melanoma growth. Materials and methods We produced a model of chronic neurogenic pain (CNP, bilateral ligation of sciatic nerves) and a model of the B16/F10 melanoma growth against the background of CNP using female/male mice of the C57BL/6 line (with normal genome, n=75) and the C57BL/6-Plautm1.1bugthisplaughfdhu/GFDhu line (with urokinase knockout (uPA), n=46). The ELISA method was used to determine the content of prekallikrein, KLK1 and KLK14 in the tumor and skin after 3 weeks of carcinogenesis against the background of CNP. Results The initially high content of prekallikrein, KLK-1 and KLK-14 in the skin of intact knockout mice was found. When inhibiting the growth and metastasis of melanoma in the skin of the knockout females, noted was a further increase in the initially high level of prekallikrein and KLK1, and in the tumor in the knockout mice of both genders recorded was a lower content of all the studied enzymes. When activating the growth of melanoma in the state of CNP in the skin of C57BL/6 mice, the level of KLK1 (female) decreased and the concentration of KLK14 (female and male) increased; in the knockout mice the content of prekallikrein and KLK14 decreased, and KLK1 changed multidirectionally. The tumor demonstrated a lower prekallikrein level in all C57BL/6mice and multidirectional changes in KLK1 and KLK14 in females and males. The tumor in the knockout animals showed a lower content of all the studied enzymes, especially pronounced for KLK14. Conclusion The content of prekallikrein, KLK1 and KLK14 varies under activating and inhibiting the growth of melanoma, the changes are of the gender-specific type. It is probable that the functions of the studied enzymes in the skin change not only in case of CNP, but also in case of urokinase deficiency. The tumor itself adapts the performance of the kallikrein-kinin system depending on the metabolic features of the tumor-bearing organism.
