Their waters are subject to anthropogenic pollution with different chemical compounds which may be significant risk factors for the health of the population. The article presents the results of comparative sanitary-hygienic characteristics of the water quality of the Oka river in places of water intake of utility and drinking water supply system of Ryazan. Being the only surface source of water supply, the Oka river provides 53% of the total water consumption of the Ryazan population, therefore a rational choice of the place of water intake can have a considerable impact on the effectiveness of water conditioning and purification and on the final quality of drinking water. \u0000AIM: To give a comparative sanitary-hygienic characteristic of the water quality of the Oka river in places of the water intake of the utility and drinking water supply system of Ryazan. \u0000MATERIALS AND METHODS: A comparative evaluation of the water quality of the Oka river, as a surface source of water supply, was carried out based on the average long-term values of control parameters (organoleptic, microbiological, chemical) and the proportion of samples that do not meet hygienic standards in the sections of three water intakes in Ryazan in 20122019. The average parameters were compared by the method of variance analysis; for paired comparisons, Scheffe and Tamhein criteria were used, taking into account the results of Levene test. The statistical parameters were calculated in SPSS Statistics 19 program. \u0000RESULTS: The chemical composition of the Oka river water was characterized by the greatest pollution with iron (2+) and aluminum. The water of Oksky and Borkovskoy water intakes was characterized by higher average concentrations of iron (2+) and ammonia, as well as greater contamination with generalized and thermotolerant coliform bacteria, compared with the water of Sokolovsky water intake. \u0000CONCLUSION: A lower initial quality of the water in Oksky and Borkovskoy water intakes may be due to their location in the 'blind' river course characterized by the processes of eutrophication and slowed down water exchange. High concentrations of iron (2+) may be associated with supply of stream water from the underground sources or with anthropogenic pollution.","PeriodicalId":113364,"journal":{"name":"I.P.

Increasing significance in the etiology and development of AAA is assigned to the existence of some genetic polymorphisms, the role of many of them is not studied either. \u0000AIM: To analyze the existence of association of the abdominal aortic aneurysm with some gene polymorphisms (GPs). \u0000MATERIALS AND METHODS: Gene polymorphisms were analyzed in 20 patients with AAA (study group, SG); 18 men (90%) and 2 women (10%), the mean age 68.1 7.3 years), and in 5 patients without AAA (control group, CG; 4 men (80%) and 1 woman (20%), the mean age 64.2 7.2 years). The frequency of concomitant diseases and risk factors for AAA were determined. The following GPs were studied: : Lys198Asn in the EDN1 gene; C-786T in the NOS3 gene; Leu28Pro in the APOE gene; Val174Ala in the SLC01B1 gene; Thr715Pro in the SELP gene; C807T in the ITGA2 gene; Ser447Ter in the LpL gene; Thr174Met in the AGT gene; Met235Thr in the AGT gene. Statistical analysis was performed using IBM SPSS Statistics 21, correlation analysis ― according to Pearson. The results were considered statistically significant at p 0.05. \u0000RESULTS: In the SG, correlation relationships were identified in Ser447Ter polymorphism in the LpL gene: direct relationships with Lys198Asn polymorphism (r = 0.63; р 0.001) in the EDN1 gene, Leu28Pro (r = 0.70; р 0.001) in the APOE gene and Thr715Pro (r = 0.63; р 0.001) in the SELP gene; a reverse relationship with С786Т polymorphism (r = -0.35; р = 0.006) in the NOS3 gene. The same amount of relationships were found in Leu28Pro polymorphism in the APOE gene: besides with Ser447Ter in the LpL gene, there is also a direct relationship with Lys198Asn (r = 0.70; р 0.001) in the EDN1 gene and Thr715Pro (r = 0.63; р 0.001) in the SELP gene; a reverse relationship with С786Т (r = -0.35; р = 0.006) in the NOS3 gene. Thr715Pro polymorphism in the SELP gene, along with relationships with Ser447Ter (r = 0.63; р 0.001) in the LpL gene and Leu28Pro in the APOE gene, has an additional direct relationship with Lys198Asn (r = 0.55; р 0.001) in the EDN1 gene.

Oxidative stress (OS) was modeled by adding hydrogen peroxide (Н2О2) at concentrations of 0.1 М100 М to the nutritive medium and incubation for 24 and 72 hours. In assessment of Nrf2 function, its inhibitor ― AEM1 ― was added to cells at a concentration of 5 М. The extent of OS development was determined using photometric methods by the concentration of protein SH-groups and carbonyl derivatives of protein, and the activity of superoxide dismutase (SOD). Viability of cells was assessed by the results of cytotoxic test (MTT assay), the amount of Nrf2 in the cytoplasm and nucleus was determined by heterogenous ELISA method. \u0000RESULTS: Incubation of Caco-2 cells with Н2О2 resulted in decrease in the level of protein SH-groups and increase in the concentration of carbonyl derivatives of protein. In incubation with H2O2 at concentrations of 0.1 М10 М for 24 hours and 10 М for 72 hours, the activity of SOD increased. At concentrations of Н2О2 of 50 М and 100 М (24 hour and 72 hour), SOD activity and viability of cells decreased. Exposure to Н2О2 led to translocation of Nrf2 from the cytoplasm into nucleus. Direct correlation dependence was revealed between concentration of protein SH-groups and the amount of Nrf2 in the cytoplasm in incubation with H2O2 for 24 hour (r = 0.44, р = 0.03), 72 hour (r = 0.34, р = 0.05). The amount of Nrf2 in the nucleus positively correlated with SOD activity in the cytoplasm on exposure to H2O2 for 24 hour (r = 0.77, р = 0.0001) and 72 hour (r = 0.36, р = 0.06). In inhibition of Nrf2 in conditions of exposure to H2O2, the viability of cells decreased to a larger extent. \u0000CONCLUSION: Hydrogen peroxide induces the nuclear translocation of Nrf2, which promotes activation of antioxidant enzyme SOD and preserves viability of cells of OS conditions in vitro.","PeriodicalId":113364,"journal":{"name":"I.P.

Determination of the length of the anteroposterior eyeball axis (APEA) in myopia ― a type of ametropia directly associated with increase in the axial length of the eyeball ― is an objective method of its diagnosis and identification of progression. Due to the fact that myopia is a multifactorial disease, the study of correlation relationships of the length of the eyeball seems to be extremely relevant. \u0000AIM: To give a statistical assessment of the peculiarities of the axial length of the eyeball in the population of the Southern Urals, depending on age, gender and the respondents' settlement sites, and to determine the correlation relationships of this parameter. \u0000MATERIALS AND METHODS: The analysis was conducted on the base of Ufa Research Institute of Ophthalmology within large clinical and population studies Ural Eye and Medical Study (UEMS) and Ural Very Old Study (UVOS). Inclusion criteria: signing of voluntary consent to participation in the project, permanent residence in the territory of study; for inclusion in UEMS ― age from 40 to 85 years, in UVOS ― age above 85. UEMS study involved 5899 respondents, UVOS ― 1526. The study protocol suggested evaluation of 683 criteria, 293 of which were answers of respondents to questions of the questionnaire and the results of the general somatic examination, 355 criteria concerned the results of the ophthalmologic examination, 35 ― of laboratory tests. Axial length of the eyeball was measured by the method of ultrasound echo-biometry (A-scanning) (Ultra-compact A/B/P ultrasound system, Quantel Medical, France). \u0000RESULTS: The mean length of the APEA in the UEMS population was 23.31 1.08 mm, in the UVOS population ― 23.11 1.08 mm (p 0.001). The length of the eyeball axis was 23.31 1.08 mm in the age group 40-84 years and 23.11 1.08 mm in patients in the age category 85 years and older. The multivariate linear regression analysis in UEMS study showed the highest statistically significant association of APEA length with such factors as age (p 0.001), height (p 0.001), presence of arterial hypertension (p = 0.02), education level (p 0.001 ), intraocular pressure (IOP) (p 0.001), spherical refractive error (p0.001), depth of anterior chamber (p 0.001) and angle of anterior chamber (p 0.001), mosaicism of the eye fundus in the macular region (p 0.001), presence of myopic maculopathy (p 0.001), refractive power of the cornea (p 0.001), corneal volume (p 0.001), macular pigment density (p 0.001), thickness of peripapillary layer of nerve fibers (p 0.001), presence of the epiretinal membrane (p = 0.01).

In the territory of the Russian Federation, the most common manifestation of Takayasu nonspecific aortoarteritis is lesion of the branches of the aortic arch, which in rare cases leads to development of the so called bald arch syndrome. In response to hypoxia, intersystemic collaterals are formed through the neoangiogenesis or redirection of the blood flow from the occluded vessels to small-diameter vessels. In patients with bald arch syndrome, the key role in blood supply to the brain is played by the vertebral arteries. Here, collateral blood supply is realized through the intersystemic anastomoses, most often through the anastomotic leaks between the intercostal and internal thoracic arteries. In the literature, single cases of formation of collaterals between coronary and bronchial arteries are reported. The article presents a clinical case of coronary-vertebral anastomoses in a patient with extremely severe course of Takayasu arteritis with occlusion of the brachiocephalic trunk, right common carotid artery (CA), left common CA, right internal CA, left internal CA (bald arch syndrome). The probable cause of such course of the disease was late referral for medical help by the patient and lack of adequate basic therapy. \u0000CONCLUSION: The demonstrated case is the fourth case in the world literature describing the existence of collaterals between the coronary arteries and cerebral arteries, and the first case in the world describing the existence of collaterals from the right and left coronary arteries to the vertebral artery. Such unusual pathway of collateral blood supply in the patient is explained by the absence of the possibility for collateral compensation from the systems of subclavian and intercostal arteries, severe chronic cerebral ischemia. Usually, the causes of angina pectoris in patients with nonspecific aortoarteritis are spread of arteritis to the coronary arteries, insufficiency of the aortic valve, hypertrophy of the left ventricle. In the described case, none of these conditions was present, and angina can only be attributed to the existence of unusual collaterals and the development of a transient steal syndrome.","PeriodicalId":113364,"journal":{"name":"I.P.

Physical fitness was assessed in conventional tests for determination of strength fitness, speed-strength fitness, speed endurance. All the data were processed using non-parametric statistical methods and correlation and cluster analysis. \u0000RESULTS: Based on the criterion of physical fitness, young men were divided to two groups: a group with a relatively high level of speed and strength endurance and flexibility (cluster 1, n = 71), and a group with a relatively high level of strength fitness (cluster 1, n = 49). Both the integral (coefficient of lateral organization profile CLOP) and partial parameters (manual and sensory asymmetry) of the functional lateralization were higher in the representatives of cluster 2, with this, the analysis of changes of the permanent potential level (method of neuro-energo mapping) in functional tests showed only an emerging tendency in the differences between the clusters.
