Aim. The article deals with studying the effect of a complex selenium-containing compound and physio disease-preventing means on the enhancement of biochemical indicators in freshmen living in a selenium-deficient area. Materials and methods. We conducted 12 longitudinal studies with the students of the first and second year studying at Chuvash Universities (n = 180). Selenium concentration in blood serum was established with the help of fluorometry performed according to Golubkina’s interpretation (Fluorat-02-2M). The activity of lipid peroxidation (c.u.) and antioxidant system (c.u.) was studied using induced chemiluminescence (Biochemiluminometer БХЛ-06). Results. The use of Selenes+ together with a disease-preventing photochrome session is accompanied by antioxidant, metabolic, and hemopoietic effects manifested in the increase of antioxidant activity and selenium concentration by 31.1 and 62.5 %, respectively, and the decrease of lipid peroxidation by 4.1–19.7 % compared to control values. The use of Selenes+ together with exercises contributes to less pronounced stress in the cardiovascular system both during the study and exam periods. Conclusion. Therefore, selenium correction of body adaptation with respect to a biogeochemical specifics of a region normalizes the balance between prooxidant and antioxidant elements of the antioxidant protection system and provides an accelerated shift from short-term to long-term adaptation.

Gardening has been positively associated with fruit and vegetable (FV) consumption based on short-term studies among children, but long-term data among adolescents and young adults are lacking. This investigation sought to elucidate the association between gardening experience and FV intake among college students over a two-year period. Students (N = 593) from eight universities were assessed at the end of their freshman (Y1) and sophomore (Y2) years during the springs of 2016 and 2017, respectively. At each time point, participants completed the NCI FV Screener and questions related to gardening experience and FV-related attitudes and behaviors. Students were then categorized into four groups based on gardening experience: Gardened only during the first or second year (Y1 only and Y2 only gardeners), gardened both years (Y1+Y2 gardeners), and non-gardeners. While both Y1 only and Y1+Y2 gardeners reported significantly higher FV intake relative to non-gardeners at Y1 (2.3 ± 0.9 and 2.6 ± 0.7 versus 1.9 ± 0.6 cup equivalents (CE)/day, respectively; p < 0.01), only Y1+Y2 gardeners differed from non-gardeners at Y2 (2.4 ± 0.6 versus 1.8 ± 0.5 CE/day; p < 0.001). Additionally, Y1+Y2 gardeners reported more frequent engagement of several FV-related behaviors, including shopping at farmers’ markets, eating locally grown foods, and cooking from basic ingredients; and were five times more likely to have gardened during childhood (OR: 5.2, 95%, CI: 3.5–8.8; p < 0.001). Findings suggest that while isolated gardening experiences during college are associated with FV intake, reoccurring experience may be essential for sustained benefit.

In consequence of ligation of the main duct in pancreatic tail section of male rats the acute pancreatitis had developed but it gradually turned into a chronic form. In the blood of experimental animals processes of lipid peroxidation (LPO), the state of antioxidant protection system (AOP), carbohydrate and lipid metabolism were studied. In rats with chronic pancreatitis the significant intensification of lipid peroxidation, inhibition of antioxidant system, hyperglycaemia, and hyperlipidaemia were found.

Background.Chronic viral hepatitis is a complex global problem and is still far from being solved. Many researchers point out influence of viral hepatitis on the reproductive system of women.Aim.To identify features of the functional state of pituitary-thyroid units of neuroendocrinal regulation, and to evaluate lipid peroxidation – antioxidant protection with determination of the oxidative stress coefficient in perimenopausal women with chronic form of hepatitis.Materials and methods. Study included 44 women with chronic viral hepatitis and 28 healthy women of the same age. Immunoabsorbent, spectrophotometric, fluorometric and statistical methods were used.Results.In patients with chronic viral hepatitis, we detected an increase in thyroxine levels – by 29.6% (р < 0.001) and free triiodothyronine values – by 65.7% (р = 0.008) in comparison with the control group. In the group with chronic viral hepatitis, the TBA-reactive products level increased by 1.9 times (р = 0.006), and superoxide dismutase activity decreased by 1.3 times (р < 0.001), total antioxidant activity – by 1.7 times (р < 0.001) and α-tocopherol level – by 1.3 times (р = 0.005) in comparison with the control group.Conclusions. The obtained data demonstrate the features of the pituitary-thyroid system functioning and the lipid peroxidation – antioxidant protection system in patients with chronic hepatitis. The chronic form of hepatitis is characterized by metabolic disorders that require a more careful approach in diagnosis and management.

Background.Today infertile marriage is not only a serious medical, but also a socio-demographic and economic problem. Male factor contributes averagely to half of the cases of the disease in couples. Such factors as high levels of reactive oxygen species and oxidative stress have been reported to compromise the process of spermatogenesis and sperm function in men. Oxidative stress is a significant risk factor for male infertility. A pro-oxidant testicular environment may alter the expression profile of functional sperm proteins and result in poor sperm quality.Aims.To study the characteristics of the intensity of the processes of lipoperoxidation and antioxidant status in the ejaculate of men with different variants of spermograms.Materials and methods.We examined 69 men with primary infertility and 155 fertile men. The content of lipid peroxidation components and antioxidant protection was determined by spectrophotometric method.Results.The results of the study in men with infertility and asthenozoospermia showed decreased total antioxidant activity of sperm by 50 % and α-tocopherol by 52 %, and in men with infertility and oligozoospermia, decreased total antioxidant activity of sperm by 47 % and α-tocopherol by 41 %.Conclusions.The analysis indicates a change in the parameters of the system of lipid peroxidation – antioxidant defense system and confirms the development of oxidative stress in them. Depending on the pathological state of the ejaculate in men of reproductive age, lipid peroxidation processes have their own characteristics. In men with oligozoospermia, peroxidation processes occur more intensively. Activation of lipid peroxidation – antioxidant defense system processes can be both a consequence and a cause of various metabolic changes in the human body.

Ronaldo Art, brand manager for J&J’s Listerine, reflected on the progress he had made in market penetration for the oral hygiene product from the time he started in the position in 2010 to late 2014. He wanted to develop a long-term strategy for the brand rather than stimulating short-term increases in market share, which could compromise the equity of the brand, its profitability, and its long-term competitive advantage. This case has been used in Darden’s second-year course “Marketing Metrics and Integrated Marketing Communications” and would work well in any course module focused on brand management and brand strategy.

This study investigated the antioxidant system response of male reproductive organs during early and late phases of diabetes and the influence of melatonin treatment. Melatonin was administered to five-week-old Wistar rats throughout the experiment, in drinking water (10 μg/kg b.w). Diabetes was induced at 13 weeks of age by streptozotocin (4.5 mg/100 g b.w., i.p.) and animals were euthanized with 14 or 21 weeks old. Activities of catalase (CAT), glutathione-S-transferase (GST), glutathione peroxidase (GPx), and lipid peroxidation were evaluated in prostate, testis, and epididymis. The enzymes activities and lipid peroxidation were not affected in testis and epididymis after one or eight weeks of diabetes. Prostate exhibited a 3-fold increase in GPx activity at short-term diabetes and at long-term diabetes there were 2- and 3-fold increase in CAT and GST, respectively (p≤0.01). Melatonin treatment to healthy rats caused a 47% increase in epididymal GPx activity in 14-week-old rats. In prostate, melatonin administration normalized GST activity at both ages and mitigated GPx at short-term and CAT at long-term diabetes. The testis and epididymis were less affected by diabetes than prostate. Furthermore, melatonin normalized the enzymatic disorders in prostate demonstrating its effective antioxidant role, even at low dosages.
