Determination of the Nutritional Habits and Anxiety Levels in Individuals with COVID-19 in Turkey

Background: Coronavirus disease 2019 (COVID-19), which has spread worldwide since December 2019, has infected and claimed the lives of millions of people. This study aimed to investigate the relationship between anxiety levels and nutritional habits of patients with COVID-19. Methods: This cross-sectional study enrolled patients diagnosed with COVID-19 between February 1, 2021 and May 1, 2021. The study population included a total of 108 individuals with COVID-19 residing in Artvin, Turkey. This study used a self-administered online questionnaire, containing 40 questions from the State and Trait Anxiety Scale. Results: The state anxiety score was 37.26, and the trait anxiety score was 39.98. A strong, positive, and significant relationship was found between the state and trait anxiety levels of the participants (r = 0.588; p < 0.001). Conclusions: Many individuals who recovered from COVID-19 still suffer and struggle with the residual symptoms of COVID-19 for several months. Symptoms such as fatigue, weakness, pain, and malnutrition may occur even after recovery

Measuring urinary 8-hydroxy-2'-deoxyguanosine and malondialdehyde levels in women with overactive bladder

Purpose: In this study, we aimed to explain the role of oxidative stress in women with overactive bladder (OAB) by investigating the levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), a marker of oxidative DNA damage, and malondialdehyde (MDA), an indicator of lipid peroxidation. Materials and Methods: A total of 90 women were included in the study: 45 female patients diagnosed with OAB at Hopa State Hospital Urology Polyclinic and 45 healthy women without any metabolic or neurologic disease. Levels of MDA and 8-OHdG were measured in 24-hour urine samples for all subjects. Results: Urinary levels of MDA and 8-OHdG were significantly higher in the OAB group than in the control group (p<0.001). A significant positive correlation (p<0.001) was found between the measurements of 8-OHdG and MDA. Conclusions: Oxidative stress may be important in the pathophysiology of OAB, because levels of 8-OHdG and MDA are increased. Increased levels of 8-OHdG may be due to damaged nuclear and mitochondrial DNA as a result of oxidative attacks caused by free radicals. Nevertheless, further randomized and prospective studies with larger patient populations are neededThis work was supported by Coordinator of Scientific Research Projects (2015.M80.02.04) at Artvin Coruh University

Association between cigarette smoking and breast milk levels of nesfatin-1, irisin, and oxidative stress markers

Background: Breast milk is a very important functional food in the prevention of metabolic and chronic diseases. This study aimed to investigate the effects of smoking during pregnancy on the concentrations of nesfatin-1, irisin, and oxidative stress markers in breast milk. Methods: This study included two groups of 14 smoking and 14 nonsmoking mothers. Malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were measured according to the spectrophotometric method in breast milk samples. Nesfatin and irisin levels were measured by enzyme-linked immunosorbent assay. Results: Levels of nesfatin-1 and MDA of the smoking group were significantly higher than those in the control group (p 0.050). Conclusions: Cigarette smoking increases MDA level and decreases SOD activity in breast milk. Nesfatin-1 levels would increase in accordance with increased oxidative stress, and nesfatin-1 acts as a protective mechanism to limit oxidative damage

The effect of sulforaphane on oxidative stress and inflammation in rats with toxic hepatitis induced by acetaminophene

OBJECTIVE: The aim of the present study was to reveal the possible effect of sulforaphane on oxidative stress and inflammation in rats liver with toxic hepatitis induced by acetaminophene. BACKGROUND: Sulforaphane is a compound with high antioxidant properties. Acetaminophen, which is a para-aminophenol derivative, can lead to fatal hepatic necrosis with direct hepatotoxic effects at high doses. METHODS: Thirty six male Sprague-Dawley rats were randomly divided into four groups. Control group (n = 9) was fed with standard rat chow and water for 3 days. Group APAP (n = 9) received a single dose acetaminophen 1 g/kg by oral gavage in addition to standard chow and water. Group SFN (n = 9) received sulforaphane 500 mu g/kg by oral gavage in addition to standard chow and water for 3 days. Group APAP+SFN (n = 9) received sulforaphane 500 mu g/kg and a single dose acetaminophen 1 g/kg by oral gavage in addition to standard chow and water. Acetaminophen was administered three hours after SFN administration. RESULTS: Neopterin, MDA, AST, ALT and CRP levels of group APAP were significantly increased compared to control group. GSH level of group APAP was significantly lower than in the control group. CONCLUSION: Sulforaphane is a protective agent against acetaminophen-induced liver damage and it can be added in the treatment protocol (Tab. 1, Fig. 5, Ref. 51). Text in PDF www.elis.sk

The effects of dietary flavonoid supplementation on the antioxidant status of laying hens

Department of Science Research Project at Artvin Coruh UniversityNinety-six 28-week-old Lohmann White laying hens were utilized to test the antioxidant effects of flavonoids (hesperidin, naringin, and quercetin at 0.5 g/kg diet) during an 8-wk experimental period. At the end of the experiment blood samples were collected to determine total protein, cholesterol, and malondialdehyde (MDA) serum levels as well as activities of glutathione reductase (GR), glutathione peroxidase (GSH-Px), glutathione-S-transferase (GST), and superoxide dismutase (SOD) and level of glutathione (GSH) in erythrocyte lysates. Data were analyzed using one-way ANOVA. Naringin supplementation did not alter serum cholesterol concentration, whereas hesperidin and quercetin supplementations decreased serum cholesterol concentration. Naringin and quercetin supplementations did not affect serum protein concentration. All flavonoids decreased MDA concentration as well as increased GSH-Px, GR, GST, and SOD activities and GSH level, being quercetion superior to hesperidin and naringin. In conclusion, flavonoids, especially quercetin, exert antioxidant activity, which may help improve wellbeing when laying hens are exposed to stressors

The effect of white tea on serum TNF-α/NF-κB and immunohistochemical parameters in cisplatin-related renal dysfunction in female rats

The study was funded by a grant from the scientific research foundation of Recep Tayyip Erdogan University .Objective: Nephrotoxicity is the most important side effect of the antineoplastic drug cisplatin, thereby restricting its use. The aim of this study was to investigate the protective effects of white tea infusions (WT) against renal damage induced by cisplatin (CP) in rats by biochemical and histopathological means. Materials and methods: This study used 24 female Sprague Dawley rats at 12–14 weeks of age and weighing 250–300 g. Rats were divided into three groups: Control, CP and CP + WT groups. CP was injected 7 mg/kg i.p as a single dose/rat in the CP group. White tea was given at a dose of 0.5% (w/v) for 4 weeks. At the end of the experiment, blood urea nitrogen (BUN), creatinine, uric acid, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and nuclear factor kappa B (NF-κB) along with caspase-3 in the kidney were evaluated in study. Results: BUN, creatinine, TNF-α NF-κB and IL-6 levels of the CP group showed a statisically significant increase in comparison to the control group. TNF-α NF-κB and IL-6 levels showed a statistically significant decrease in the CP + WT group with respect to the CP group. Caspase-3 levels in tubular epithelial cells decreased in CP + WT group compared with CP group (p = 0.02). Conclusion: White tea infusions reduced significantly the nephrotoxicity of CP. The anti-nephrotoxic feature of the infusion may be attributed primarily to its anti-inflammatory and anti-apoptotic characteristics

Astaxanthin alleviates renal damage of rats on high fructose diet through modulating NF kappa B/SIRT1 pathway and mitigating oxidative stress

Coordinator of Scientific Research Projects at Artvin Coruh University: 2016.M80.02.08This study was conducted to determine the effect of astaxanthin (ASX) treatment on alleviation ofrenal damage in high fructose induced nephrotoxicity in rats. Treatments were arranged in a 2 2 fac-torial fashion: administrations of fructose (30%, via drinking water) and ASX (1 mg/kg/day, within0.2ml olive oil) for 8 weeks. Data were analyzed by two-way ANOVA. The ASX treatment decreasedserum urea (p<.01) and blood urea–N concentrations (p<.02) at a lower extent in rats receiving fruc-tose than those not receiving fructose. Moreover, the ASX treatment reversed the increases in malon-dialdehyde (MDA) (p<.0001) and nuclear factor kappa B (NF-jB) (p<.0003) levels and the decreasesin superoxide dismutase (SOD) activity (p<.0001) and sirtuin-1 (SIRT1) level (p<.0004), in the kidneyupon high fructose consumption. The data suggest that ASX supplementation alleviates renal damageinduced by high fructose consumption through modulating NF-jB/SIRT1 pathway and mitigating oxi-dative stress
