Trimethylamine-N-oxide (TMAO) is a gut microbiota-derived metabolite recognized as strongly related to cardiovascular diseases (CVD), mainly increasing the risk of atherosclerosis development. Currently, no pharmacological approaches have been licensed for reduction of TMAO serum levels and conventional anti-atherosclerosis treatments only target the traditional risk factors, and the cardiovascular risk (CVR) still persist. This underlines the need to find novel targeted strategies for management of atherosclerosis. In this study we tested the ability of a novel nutraceutical formulation based on grape pomace polyphenols (Taurisolo®) in reducing both the serum levels of TMAO and oxidative stress-related biomarkers in humans (n = 213). After chronic treatment with Taurisolo® we observed significantly reduced levels of TMAO (−49.78 and −75.80%, after 4-week and 8-week treatment, respectively), oxidized LDL (oxLDL; −43.12 and −65.05%, after 4-week and 8-week treatment, respectively), and reactive oxygen species (D-ROMs; −34.37 and −49.68%, after 4-week and 8-week treatment, respectively). On the other hand, no significant changes were observed in control group. Such promising, the results observed allow indicating Taurisolo® as an effective nutraceutical strategy for prevention of atherosclerosis.Clinical Trial Registration: This study is listed on the ISRCTN registry with ID ISRCTN10794277 (doi: 10.1186/ISRCTN10794277).

Aims Physical activity is usually accompanied by free radicals’ production and oxidative stress. Moreover, to prevent adverse effects, coaches and athletes have to use proper supplementation. Therefore, the present study aimed to investigate the effect of short-term coenzyme Q10 supplementation on malondialdehyde and serum catalase enzyme activity following moderate and severe acute resistance training in inactive female students. Methods & Materials In total, 27 female students were randomly divided into three groups; the groups were homogeneous and equal (two groups of resistance training and one control group). The experimental groups were subjected to moderate-intensity acute (70% 1RM) acute and severe acute activity (85% 1RM) and supplemented with coenzyme Q10 (30 mg /d). CAT and MDA were measured in ELISA using a human kit. Findings Moderate and severe acute resistance activities did not alter MDA and catalytic activity (P>0.05); however, after 2 weeks of coenzyme Q10 supplementation, those resulted in a significant decrease in MDA (0.006 and 0.01, respectively) and CAT (0.04 and 0.007, respectively). There were no significant differences between the effects of two exercises (P>0.05). Conclusion Short-term (two weeks) supplementation of coenzyme Q10 and severe acute resistance activity could reduce two important oxidative stress indexes (MDA and CAT).

Цель исследования: выявить взаимосвязь между дислипидемией, активностью воспаления и функцией тромбоцитов в развитии атеросклероза у пациентов с системной красной волчанкой (СКВ), а также оценить сходство и различия механизмов атерогенеза у больных СКВ и ишемической болезнью сердца. Материалы и методы. Обследовано 102 женщины, из них — 50 больных СКВ, 31 — с инфарктом миокарда (ИМ); контрольную группу составили здоровые женщины (n = 21). Определяли показатели липидного спектра, содержание антител к окисленным липопротеинам низкой плотности (АТ-оксЛПНП), высокочувствительного С-реактивного белка (вчСРБ), интерлейкина 6 (ИЛ-6), тромбоцитарного фактора 4 (ТФ4), агрегационную функцию тромбоцитов и толщину комплекса интима-медиа (ТКИМ) общих сонных артерий. Результаты. У больных СКВ и у пациентов с ИМ выявлено значительное увеличение ТКИМ сонной артерии и выраженная активация воспаления: повышение содержания вчСРБ, ИЛ-6 и увеличение СОЭ. За исключением значений ИЛ-6, лабораторные показатели воспаления у больных СКВ и с ИМ достоверно не различались. Также у пациентов с СКВ и ИМ установлена значительная активация тромбоцитов (достоверный рост содержания ТФ4). Несмотря на наличие дислипидемии в обеих группах, у больных СКВ данные изменения были выражены более отчётливо и сопровождались повышением уровня АТ-оксЛПНП. Заключение. Кроме традиционных факторов риска развития сердечно-сосудистых заболеваний, ассоциация между СКВ и атеросклерозом может быть объяснена дополнительными факторами риска — воспалением и аутоиммунными процессами. Aim: to reveal a relationship between dyslipidemia, infl ammatory activity and platelets reactivity in atherosclerosis development in patients with systemic lupus erythematosus (SLE) and also to assess the similarity and diff erences of atherogenesis mechanisms in patients with SLE and ischemic heart disease. Materials and methods. The study included 102 women: 50 patients with SLE, 31 — with myocardial infarction (MI); control group included 21 healthy women. We measured parameters of lipid spectrum, levels of antibodies against oxidized low density lipoproteins (oxLDL), high-sensitive C-reactive protein (hsCRP), interleukin 6 (IL-6), platelets factor 4 (PF4), platelets aggregation activity and complex intima-media thickness (TCIM) of carotid arteries. Results. Patient with SLE and MI had markedly increased TCIM. Increased infl ammation activity was the second sign of two groups of patients, including increased hsCRP, IL-6, erythrocyte sedimentation test. Laboratory signs of infl ammation did not markedly diff er in two groups except IL-6. Our study also revealed considerable platelets activation in patients with SLE and MI (signifi cant growth of PF4 content). Despite dyslipidemia, all indicated changes were more clearly expressed in patients with SLE; they were accompanied by increased level of antibodies against oxLDL. Conclusion. Except traditional risk factors for cardiovascular diseases development the association between SLE and atherosclerosis. can be explained by additional risk factors — infl ammation and autoimmune processes.

Purpose: To determine the curative impact of mesalazine (MSZ)-BTVCs combination on ulcerative colitis (UC), and its influence on inflammation and oxidative stress in the patients.Methods: 100 UC patients were randomely assigned to a control group given MSZ capsule treatment only, and a combination group treated with BTVCs and MSZ. Treatment effectiveness, inflammatory response, and oxidative stress in the two groups before and after treatment were compared.Results: The combination group had higher total effectiveness than the control group. The serum levels of MDA, high-sensitivity C-reactive protein (hs-CRP), TNF-α and interleukin-6 (IL-6) were lower, while serum levels of superoxide dismutase (SOD) and interleukin-10 (IL-10) were markedly increased in patients given combination treatment, when compared with controls. Pre-drug exposure UC disease activity index (UC-DAI) and clinical symptom scores were similar in both cohorts of patients, but the post-treatment scores were statistically decreased, especially in the combination group.Conclusion: The combined use of MSZ and BTVCs was more effective against UC than monotherapy, as it effectively relieved inflammation and oxidative stress in patients, resulting in better clinical efficacy.

This study was to compare the impact of different biocompatible coated circuits on inflammatory response and oxidative stress induced during cardiopulmonary bypass (CPB). Seventy-eight patients undergoing elective coronary artery bypass grafting (CABG) with CPB were randomly assigned to five groups with different biocompatible coated circuits: Trillium, Bioline, Phosphorylcholine, Polymethoxyethyl acrylate (PMEA), and the uncoated control group. Blood was drawn at three different time points: before CPB, 6 and 72 hours post CPB. Unlike the Trillium group, serum levels of TNF-α in the Bioline and Phosphorylcholine groups significantly increased only at 72 hours post CPB (p < 0.05). Serum levels of IL-6 significantly increased at 6 and 72 hours post CPB in all groups (p < 0.01). The Trillium group showed a significant increase of IL-10 compared to the control group at 72 hours post CPB (p < 0.05). Serum levels of NOx in the Phosphorylcholine group significantly decreased at 6 hours post CPB compared to baseline (p < 0.05). Both the Bioline and Phosphorylcholine groups showed statistical decreases in serum NOx levels compared with other groups at 6 hours post CPB (p < 0.05). A significant difference in NOx levels between the Bioline and the control group was also observed at 72 hours post CPB. Myeloperoxidase levels were significantly elevated at 6 and 72 hours post CPB in all groups (p < 0.05). Inflammatory response and oxidative stress are elevated during CABG with CPB. Heparin-coated and the Phosphorylcholine-coated circuits induce less inflammatory responses and oxidative stress compared to other circuits.

Oxidative stress represents the imbalance between the production of reactive oxygen species and the organism�s capacity to produce antioxidants. This phenomenon has captured lately a lot of attention, with an additional increased interest being manifested towards the relationship between psychological stress and oxidative stress. In the present study we decided to observe the changes which occur in stress environmental conditions applied to rats subjected to swimming and treadmill exercises, by focusing on a preliminary determination of (CAT) specific activity, an enzyme known to catalyse the decomposition of hydrogen peroxide into water and oxygen, and a valuable antioxidant protector, with possible implications into the dry eye pathology. Our results could suggest a possible dry eye animal model induced through stress and a possible implication of the oxidative stress markers in the occurrence of this ocular pathology, as suggested by the significant decrease in the CAT activity registered in rat tears collected after the application of environmental stressors (e.g. swimming and running) versus the control group.

Abstract Background: Oxidative damage is of great importance for patients with breast cancer. Thus, studies were performed to identify the relationship between breast cancer and oxidative stress biomarkers. Objectives: In this study, our aim was to find out the oxidative and antioxidant status, serum thiol-disulphide levels in subjects with breast cancer. Methods: This study was conducted between March and June 2018 with 82 control subjects (aged between 32-67 years) and 127 breast cancer patients (aged between 27-66 years) (p=0.058) in Selcuk University Faculty of Medicine, Konya, Turkey. Serum myeloperoxidase (MPO), catalase, prolidase were analyzed with kinetic spectrophotometric and thiol-disulphide, ischemia-modified albumin (IMA), ceruloplasmin were detected by colorimetric methods. Results: Serum levels of catalase [199.3 (16.4-489.9) vs 81.6 (18.2-322.9) (kU/L)], MPO [124±28 vs 101±31 U/L], disulphide [25 (11-61) vs 18 (2-41) µmol/L], IMA [0.66 (0.31-3.30) vs 0.62 (0.19-1.31) absorbance unit (ABSU)] and prolidase levels [2217±538 vs 1456±401 U/L] were higher in patients than control subjects (For all p<0.001 except for IMA p=0.031). Native thiol [342±60 vs 391±52 µmol/L] and total thiol levels [396±56 vs 430±52 µmol/L] were lower in patients compared with the control group (For all p<0.001). Conclusions: Levels of serum thiol/disulphide and prolidase might be reliable indicators for determining oxidative status in certain patient populations.

Abstract Introduction The detection of inflammatory mediators in the serum of children with have otitis media with effusion (OME) and their correspondence with clinical considerations may enable the use of a modern nonsurgical curative treatment for OME. Objective To determine the relation between interleukin-17 (IL-17) serum level and reactive oxygen species (ROS) serum levels in children suffering from OME and to disclose if any variation occurs in the level of IL-17 Will affect the ROS and antioxidant equilibrium in the serum, which indicates the entire body's reaction to OME. Methods The present study was a case-control study. A total of 24 children experienced OME, and 24 healthy controls were recruited.All participants in the study were subjected to a systematic clinical investigation including otoscopic, audiometric, and tympanometric examination. Also, venous blood samples were collected from all children to determine the levels of IL-17 and ROS. Results The mean ± standard deviation (SD) age ranges of the patients and the control group were 6.8 ± 2.7 and 6.2 ± 3.4 years, respectively. A stylistically significant difference in the levels of serum nitric oxide (NO), catalase (CT), myeloperoxidase (MPO), and malondialdehyde (MDA) (p < 0.05) was detected between OME and control patients. No significant difference was found in serum levels of superoxide dismutase (SOD) and glutathione peroxidase (GPX) between OME and control patients. The serum levels of MDA, NO, and MPO positively correlated with the serum levels of IL-17 in OME patients. Conclusion In the present study, there is a reasonable role of the IL-17 pathway in OME pathogenesis through an increase in ROS levels.

Objectives: To evaluate the frequency of non-alcoholic fatty liver disease, the retinol serum levels, lipid profile, and insulin resistance in overweight/obese children. To relate these biochemical variables with the risk of this disease in the population studied. Methods: The study was cross-sectional and prospective, with 46 overweight/obese school children (28 female, 18 male; mean age 8.6 years). The control group consisted of 45 children, paired by age and gender. Hepatic steatosis, evaluated by ultrasound, was classified as normal, mild, moderate, or severe. Also evaluated were serum retinol levels; thiobarbituric acid reactive substances; lipid profile; and fasting glucose and serum insulin levels, used for the calculation of the Homeostasis Model Assessment. Results: Hepatic ultrasound alterations were found in 56.5% and 48,9% of the overweight/obese and control group children, respectively. Presence of obesity was associated with high levels of triglycerides (OR = 4.6; P = 0.002). In the studied children, the risk of steatosis was related to a trend to a higher percentage of retinol inadequacy (OR = 2.8; p = 0.051); there was no association with thiobarbituric acid reactive substances, lipid profile, or insulin resistance. Conclusions: The high frequency of non-alcoholic fatty liver disease in both groups, evaluated by hepatic ultrasound, in low-socioeconomic level children, independent of nutritional condition and without significant association with insulin resistance, emphasizes that especially in developing countries, other risk factors such as micronutrient deficiencies (e.g. vitamin A) are involved.

Introduction: Tuberculosis (TB) and especially resistant forms of it have a substantial economic burden on the community health system for diagnosis and treatment each year. Thus, investigation of this field is a priority for the world health organization (WHO). Cytokines play important roles in the relationship between the immune system and tuberculosis. Genetic variations especially single nucleotide polymorphisms (SNPs) impact cytokine levels and function against TB. Material and Methods: In this research SNPs in IFN-γ (+874 T/A) and IL-10 (-592 A/C) genes, and the effects of these SNPs on cytokine levels in a total of 87 tuberculosis patients and 100 healthy controls (HCs) were studied. TB patients divided into two groups: 1) 67 drug-sensitive (DS-TB) and 2) 20 drug-resistant (DR-TB) according to drug sensitivity test using polymerase chain reaction (PCR). For the genotyping of two SNPs, the PCR-based method was used and IFN-γ and IL-10 levels were measured by ELISA in pulmonary tuberculosis (PTB) and control group. Results: In -592A/C SNP, only two genotypes (AA, AC) were observed and both genotypes showed statistically significant differences between DR-TB and HCs (p=0.011). IL-10 serum levels in PTB patients were higher than HCs (p=0.02). The serum levels of IFN-γ were significantly higher in DS-TB patients than that of the other two groups (p<0.001); however, no significant differences were observed for allele and genotype frequencies in IFN-γ +874. Conclusions: Our results suggest that the SNP at -592 position of IL-10 gene may be associated with the susceptibility to DR-TB. However, further investigation is necessary.
