Abstract Background and Aims Antibodies to M-type phospholipase A2 receptor (PLA2R-Ab) are considered to be a promising biomarker for laboratory diagnosis of primary membranous nephropathy (PMN) and may be useful in the evaluation of the response to therapy and CKD prognosis. The aim of the study was to compare two immunoassay methods – indirect immunofluorescence (IIF) and enzyme immunoassay (ELISA) for the determination of circulating PLA2R-Ab in patients with PMN. Method The study included 54 patients aged 55 (40-63) yrs. (M: F [33:21]) with PMN before treatment (n=16) and treated with immunosuppressive therapy (IST) (n=38), and apparently healthy individuals of the corresponding gender and age (n=10). Proteinuria and estimated glomerular filtration rate (eGFR) were determined in all participants. The levels of PLA2R-Ab were determined by IIF and quantitative/ semi-quantitative ELISA (EURUIMMUN AG test, Germany). In 16 PMN patients without treatment and 28 PMN patients treated with IST the level of PLA2R-Ab was measured one time and in 10 PMN patients treated IST – in dynamic, from 2 to 5 times. Statistical comparisons among groups were performed using Mann–Whitney U-test and Kruskal-Wallis H tests. The association between variables was estimated using Spearman’s coefficient. Sensitivity and specificity of the methods were calculated. Results The correlation coefficient between IIF and ELISA was 0.82 (p <0.005). There were more PLA2R-Ab-positive cases detected by ELISA, both before treatment (ELISA - 80%, IIF - 67%) and among patients treated with IST (ELISA - 63%, IIF - 50%). In control group, ELISA showed no positive results for PLA2R-Ab (specificity was 100%). The levels of proteinuria and eGFR were associated with autoantibodies determined by ELISA, both quantitative and semi-quantitative (proteinuria: r = 0.69, p = 0.001; eGFR: r = -0.38, p = 0.035) but not by IIF (proteinuria: r=0.33, p=0.061; eGFR: r=-0.26, p=0.082). The levels of PLA2R-Ab measured by ELISA correlated with the course of disease in patients treated with IST, while IIF did not show any dynamics is some cases. Conclusion Both quantitative and semi-quantitative ELISA were considered to be more preferable methods since the obtained results correlate with renal dysfunction and allow to assess the concentration of PLA2R-Ab in the course of disease more accurately, that may contribute to timely correction of treatment and improvement of outcome.

The aim of the study: To estimate the level of Galectin-3 with the parallel tracing of the content of pro- and anti-inflammatory cytokines Interleukin-6 (IL-6) and Interleukin-4 (IL-4) for patients with GERD and BA both in case of separate nosologies, and in case of their combined course during the period of exacerbation of the diseases. Methods. The study was conducted in three groups of patients, homogeneous by gender and age. The first group included 18 patients with GERD. The second group included 19 patients with intermittent or persistent-mild bronchial asthma. The third group included 22 patients suffering from GERD with concomitant BA intermittent or persistent-mild severity. Determination of the level of galectin-3 and interleukins (IL-4 and IL-6) in the blood serum was carried out by enzyme-linked immunosorbent assay. Results. Analyzing the results of the study, we found that the level of galectin - 3 was increased on average in both groups of patients with isolated GERD (and in patients with BA). In patients of the third group with comorbid pathology, the level of galectin-3 was statistically significantly higher than not only the norm, but also the average of patients with isolated BA and GERD. At the same time, we found the rise in the level of pro-inflammatory (IL-6) and anti-inflammatory (IL-4) cytokines. Moreover, in patients with GERD, the level of IL-6 was increased with a higher degree of reliability, and the level of IL-4 was increased with a lower degree of reliability. In patients with BA, on the contrary, the level of IL-4 was determined more often and higher, and the level of IL-6 was lower. Conclusions. Analyzing result of the study, a clear correlation and features of changes in the level of galectin-3, IL-4, IL-6 in patients with isolated GERD, BA, as well as with the comorbidity of these diseases, were revealed. In patients with BA, the level of galectin-3 increases with the same degree of certainty as in the group of patients with GERD. In the cytokine system, on the contrary, the level of anti-inflammatory (IL-4) cytokines increases with a greater degree of certainty than the level of pro-inflammatory (IL-6) cytokines. In patients with GERD with concomitant BA, the level of galectin-3 increases with a greater degree of certainty. It is observed also a higher rising of pro-inflammatory (IL-6) cytokines and a slightly pronounced increasing of the level of anti-inflammatory (IL-4) cytokines in comparison with the group of patients with isolated GERD.

School age children (pedestrians) can move at different speeds, which are conditioned by certain parameters. Not all parameters have the same effect on the pedestrian speed. According to the literature, gender and age are the most researched parameters that have an impact on the speed of pedestrians. However, a small number of authors have dealt with the influence of movement regimes (slow, normal, fast, run, and rush) on pedestrian speed, while at the same time taking into account age and gender. For that reason, this article measured the speed of movement of school age children by movement regimes, taking into account age and gender. Within the same movement regime, the influence of age, sex, height, and weight on the speed of movement was investigated. Experimental measurements of the speed of movement of pedestrians aged 7 to 20 years were performed. Based on the results of measurements and statistical analyzes, recommendations on the average speed of movement regimes, age, and gender are given.

Objective: to assess the state of the pro-oxidant/antioxidant system in children with hereditary spherocytosis (HS) depending on its severity.Material and methods. The study involved 44 HS patients at the age from 1 to 17 who were divided into 2 groups depending on the disease severity: mild course (n = 24) and moderate or severe course (n = 20). The control group included 23 practically healthy children who were comparable with the main group by gender and age. The state of the pro-oxidant/antioxidant balance of blood plasma was assessed by the method of luminol-dependent chemiluminescence (LDCL) with the determination of the maximum luminescence intensity (Imax, %) and the light sum of chemiluminescence (S, %). The activity of superoxide dismutase (SOD) and catalase was determined in the erythrocytes of the examined children.Results. On average, the parameters of the pro-oxidant/antioxidant status in the HS patients significantly differed from those of the control group (p <0.05), which corresponded to moderately pronounced oxidative stress. The activity of SOD and catalase in the erythrocytes of the patients was higher as compared with that of the control group (p = 0.0001 and p <0.0001, respectively). The comparison of the severity of oxidative stress depending on HS severity has determined that the degree of stress was more pronounced in patients with moderate or severe course of the disease (p <0.05).Conclusion. HS patients develop oxidative stress (decreased activity of the antioxidant system associated with increased accumulation of prooxidant substances), the degree of which is higher in patients with a severe course of the disease. This allows of considering plasma LDCL indicators as an additional marker for the assessment of the severity of the disease and of justifying the necessity to include antioxidants in the HS treatment regimen.

Acute hellebore poisoning is characteristic for the Russian Federation because of the use of this plant for the treatment of alcoholism at home. The varying severity of clinical symptoms, which sometimes become lifethreatening, the lack of anamnestic reliable information about the use of hellebore and the difficulties of chemical and toxicological confirmation of its use complicate the diagnosis of acute poisoning, and do not allow timely medical care. In addition, there is no classification of hellebore poisoning in ICD-10, block (T51-T65), which also affects the assessment of the actual frequency of this acute intoxication. The purpose of this work is to clarify the number of acute hellebore poisoning in the Russian Federation. The analysis of medical records of patients hospitalized with acute hellebore poisoning in toxicological departments of a number of subjects of the Russian Federation for 2014 - 2018 was carried out. The dynamics of such acute poisoning over the specified period, the gender and age composition of victims, and the circumstances of poisoning were revealed. The relevance of developing methods of chemical and toxicological analysis for the determination of hellebore alkaloids is confirmed, which will increase the reliability of diagnosis and detection of cases of hellebore poisoning.

The aim of the study is to investigate the effects of age, sex, running distance and origin of horse on racing speed for Purebred Arabian horse in Tunisia. Although the occidental type is known to be more successful in racing than the Tunisian type, we undertook this study to try to confirm or deny this supremacy for a sample of racehorses born in Tunisia from occidental father. A total of 333 racing records were considered for race performance. The effects of environmental factors on (sex, age, father’s origin, race distance, number of race seasons) race performance were analyzed using the least-squares method(LSM).The racehorses studied were all Arabian Purebred horses in operation at the racecourse of Ksar Said from 2010 to 2020. They are 180 horses, 90 horses born of a Tunisian father, and 90 horses born in Tunisia ofthe occidentalfather. These horses are the best and most successful in their category. The study revealed that the gender and age effectswere statistically insignificant onracingperformance. Race performance was significantly influenced by the distance and the origin of the father which affirms the improving role of the occidentalhorse in the Tunisian population.

The difference in the characteristics of craniofacial structures in different races and ethnicities established in many studies requires the creation of a normative basis for teleroentgenographic indices and indices characteristic for a particular ethnic group. The purpose of the work is to set the cephalometric parameters by W. Downs for young men and women from Podillya region of Ukraine with orthognathic bite and compare the results with the data proposed by the author of the technique. With the device Veraviewepocs 3D device, Morita (Japan), 38 young men (17 to 21 years of age) and 55 young women (aged from 16 to 20 years) with orthognathic bite (normal occlusion close to orthognathic bite) received and analyzed lateral teleroentgenograms. Cephalometric points and measurements were performed in accordance with the recommendations of W. Downs (1948). Anatomical points were determined taking into account recommendations A.E. Athanasiou (1997), S.I. Doroshenko and Y.A. Kulginsky (2007). The statistical processing of the obtained results was carried out in the licensed package “Statistica 6.0” using nonparametric methods for evaluating the obtained results. As a result of the research, virtually no sex differences in cephalometric parameters by W. Downs between adolescents from Podillya with orthognathic bite were found. When comparing the cephalometric parameters obtained by W. Downs from similar figures obtained in Ukrainian young men and women with orthognathic bite, regardless of gender, established significantly lower values of Cant Occlusal Plane (angle POr-DOP) and angle II, as well as significantly higher values were established for angle 1l-DOP, angle 1l-MeGo and distance 1u-APog in Ukrainian young men and women of Podillya. The obtained results indicate the need to create a normative base for cephalometric standards by W. Downs for the population of different regions of Ukraine, taking into account gender and age belonging.
