ABSTRACT
The aim: The objective of the research was to study the indicators of oxidative modification of proteins (OMP) and the activity of matrix metalloproteinase-9 (MMP-9) in patients with paranoid schizophrenia depending on the disease duration.
Materials and methods: 320 patients were included in the examination. 20 patients were with “Primary psychotic episode” (Comparison Group) and 300 patients were diagnosed with “Paranoid schizophrenia” (Experimental Group): 60 of them have suffered from this disease for a duration from 3 to 5 years (Subgroup I ); 60 patients have sufferedfor a period from 6 to 10 years (Subgroup II); 60 individuals – from 11 to 15 years (Subgroup III); 60 patients have suffered for a duration from 16 to 20 years (Subgroup IV); 60 patients – from 21 years and longer (Subgroup V).
Results: The presented data showed that the levels of OMP indicators in Subgroup I constituted 0.826±0.046 conventional units at a wavelength of 356 nm; 0.864±0.051 conventional units at a wavelength of 370 nm; 0.444±0.019 conventional units at a wavelength of 430 nm; 0.176±0.007 conventional units at a wavelength of 530 nm, which is 1.99; 1.6; 1.13 and 1.43 times higher than in the Comparison Group. The content of OMP products was higher by 2.24; 1.74; 1.17, and 1.43 times in Subgroup II, respectively, by 2.4; 1.80; 1.36 and 1.46 times in Subgroup III, respectively;by 2.5; 1.9; 1.4; 1.6 times in Subgroup IV, respectively; by 2.5; 2.02; 1.54; 1.7 times in Subgroup V, respectively. The conducted correlation analysis indicated a direct correlation between OMP indicators and the disease duration. The concentration of MMP-9 in the patients of the Comparison Group was equal to 892.84±87.80 pg/ml, which was 11.2% less compared to the Experimental Subgroup I, where this indicator was 992.84±67.50 pg/ml. MMP-9 constituted 1092.53±47.20 pg/ml on average in the patients of Subgroup II, which was 22.36% higher than in the Comparison Group. This indicator was 1702.84±37.60 pg/ml in Subgroup III, which was 90.7% higher than in the Comparison Group. It constituted 1492.84±47.29 pg/ml in Subgroup IV, which was 67.2% higher than in the Comparison Group;and 2037.21±57.80 pg/ml in Subgroup V, which was more than two times higher than in the Comparison Group (p<0.05). The conducted correlation analysis showed a direct relation between MMP-9 expression and the increase in OMP indicators. This relation was more significant between MMP-9 and OMP products of a neutral nature. The correlation strength between MMP-9 and OMP products of a basic nature was somewhat less significant.
Conclusions: According to the results of the conducted analysis, the examined patients hadthe signs of decompensation of reactive-adaptive biomolecular mechanisms which activated radical reactions with the subsequent accumulation of oxidation products. 

Abstract

Objective: The aim: The purpose of this study was to examine the most common coping strategies in the population in quarantine settings.

Patients and methods: Materials and methods: The study used the following set of methods: a general questionnaire aimed at studying sociodemographic data, living conditions during quarantine, lifestyle during quarantine, the presence of chronic diseases and psychodiagnostic methods: assessment of distress R.Kessler, assessment of the presence of manifestations of anxiety-depressive response GAD-7, depression self-assessment scale PHQ-9, stress-overcoming behavior strategies (E. Heim), as well as mathematical methods for processing the obtained data.

Results: Results: Social and psychological characteristics of the examined were investigated, where coping strategies during the quarantine period play a role in the adaptation process and the state of the psychoemotional sphere. Non-adaptive cognitive coping was characterized by the presence of direct strong correlations with high levels of distress and high rates of anxiety and depression.

Conclusion: Conclusions: Quarantine restrictions are risk factors for mental health deterioration. In these settings, the interaction of stress factors with anti-stress protection components is important, among which coping strategies play a leading role.

Angiographic examination of the coronary arteries – coronary angiography allows for intravital evaluation of the coronary arteries. Structural lesions of the coronary arteries are a prerequisite for developing coronary heart disease, the most common form of cardiovascular disease among women. The work aimed to carry out a morphometric analysis of coronary artery valves in women in normal conditions and under coronary artery damage, with an assessment of the relationship between age and anthropometric indicators. Angiographic images of the coronary arteries of 56 normal women and those with structural lesions of the coronary arteries served as materials and methods. Used methods: coronary angiography, mathematical and statistical calculations. In women with lesions of the coronary arteries, the height of the left coronary artery ostia (4.78±1.16 mm) exceeded the height of the right coronary artery ostia (3.94±0.98 mm) (p=0.003). Similar differences were found in women without lesions of the coronary arteries, in particular, the height of the left coronary artery ostia was 5.96±0.91 mm, the height of the right coronary artery ostia was 4.58±1.10 mm (p<0.0001). The height of the ostia of the left (p=0.0001) and right (p=0.027) coronary arteries prevailed in healthy patients, compared to the group with coronary artery lesions. According to the analysis of the combined effect of several factors on the height of the coronary artery valves, it was established that with increasing age, height (r=-0.35, р=0.047) and body surface area (r=-0.37, р=0.035) decreased. Height was directly correlated with body weight (r=+0.36, p=0.043). According to the results of the paired correlation, a direct correlation of average strength between height and body weight (r=+0.49, p=0.014) and body surface area (r=+0.63, p=0.001) was proved. Thus, with the help of the angiographic method of research, various relationships between the height of the coronary artery ostia and the age-anthropometric parameters in women with coronary artery lesions and under normal conditions were established.

Динамічний розвиток ендоваскулярних кар-діологічних інтервенційних процедур сприяє дослідженню серцево-судинної системи in vivo [1]. Прижиттєву оцінку вінцевого русла серця можна оцінити з допомогою комп’ютерної томо-графії з контрастуванням, черезстравохідного ультразвукового дослідження, ангіографії-коронарографії та внутршіньосудинного ультра-звукового дослідження (intravascular ultrasound, IVUS). Для морфологів важливою перевагою останнього є можливість оцінити анатомію та геометрію вінцевих артерій з люменальної пове-рхні судини [2]. Поступове впровадження методик в Україні результує у досить лімітовані публікації, які но-сять несистемний характер. Більше цього, ми не зустрічали даних у фаховій україномовній літе-ратурі про аналіз розмірів вічок вінцевих артерій та кореляції з віковими, гендерними чи антропо-метричними показниками. Враховуючи, що серцево-судинні захворю-вання досі є лідером з летальності в Україні та світі [3], логічним є необхідність максимального вивчення морфології та проведення морфометрії структур, які на це впливають. Власне тому, ми акцентуємо нашу увагу саме на вінцевих артері-ях, які кровопостачають серце і уражаються при виникненні іхемінчої хвороби серця [4].

Aortic root requires preliminary preoperative analysis for coronary artery bypass graft (CABG) in coronary heart disease (CHD). The dimensions of the aorta correlate with anthropometric indicators. The purpose of the study: to establish the relationship between sinuses of Valsalva height, coronary artery ostia height and biometric parameters (age, height, weight, body surface area and body mass index) in men with CHD using computed tomography. Research materials and methods include contrast-enhanced computed tomography images of the aorta of men with verified CHD. According to growth parameters, division into 2 groups was made. The sinuses of Valsalva height and right and left coronary artery ostia height were measured. Clinical data were analyzed: age, height, body weight, body surface area (BSA) and body mass index (BMI). Statistical analysis: Student's t-test, Kendall's rank correlation method, Pearson's linear correlation, Fisher's multifactorial regression analysis. Analysis of the results of computed tomography of 30 men with CHD (average age 60.80±10.63 years) showed that the average values of the three sinuses of Valsalva height were approximately at the same level. The results of the Pearson linear correlation evaluation showed the absence of a proven relationship between biometric indicators and morphometric data according to CT in men with CHD (p>0.05). Multifactor regression analysis proved the inverse significant influence of weight and the direct significant influence of BMI and BSA on the dependence of left coronary artery ostia height. The multiple correlation coefficient was R=+0.55, with p=0.023, SEE=2.74. Prediction
of the level of left coronary artery ostia height in men with CHD was carried out with confirmation of the constructed model. In the first group of short men (n=11) with CHD (average age 60.11±12.63 years, height 1.677±0.023 m), an inverse correlation between height and left coronary artery ostia height (tb=-0.56, p=0.034). Reliable direct relationships between the left coronary artery ostia height parameter and several anthropometric indicators were established: with weight - a direct strong relationship (tb=+0.72, p=0.007), with BMI - a direct relationship of medium strength (tb=+ 0.67, p=0.008), with BSA - average strength direct connection (tb=+0.58, p=0.023). The relationship between the value of the right coronary artery ostia height and the BSA indicator - the inverse of the average strength correlation (tb=-0.51, p=0.046) was proved. Relationships between morphometric parameters and age were not proven. Thus, in men with CHD, left coronary artery ostia height correlates with weight, BMI, and BSA. In short men with CHD, there is
an inverse relationship between left coronary artery height and height; direct relationships with weight, BMI and BSA.
