    Aim: Oxidative stress has been a significant factor in wound-healing pathophysiology for a long time. Antioxidants, especially natural compounds, have recently been emphasized in instructions for wound healing treatments. Jaceosidin (JACE), a flavone derived from Artemisia princeps, is a potent antioxidant. This study aims to investigate JACE’s anti-inflammatory and antioxidant properties and its capacity to improve the effects of in vitro wound healing. Methods: Wound healing activities have been tested using cell proliferation and migration in vitro assays in the mouse fibroblast cell line L929. The concentration of hydrogen peroxide (H2O2-0.5 mM) has been used to induce the oxidative stress model. Tumor necrosis factor-alpha (TNF-α) and nuclear factor (NF-kb) have been investigated as inflammatory indicators. Antioxidant activity has been checked using total antioxidant status (TAS) and total oxidant status (TOS) tests. Results: JACE has significantly increased the proliferation of fibroblasts dose-dependent manner. It has enhanced the cell migration rate of fibroblasts compared with the H2O2 group. JACE at a concentration of 50 and 100 μM has significantly decreased TOS and oxidative stress index (OSI) levels and increased TAS levels. The anti-inflammatory mechanism of JACE has involved down-regulation of the mRNA expressions of the NF-kb  and TNF-α in a dose-dependent manner. Conclusions: JACE has beneficial impacts on fibroblast viability and migration qualities through antioxidative actions and down-regulating proinflammatory cytokines through anti-inflammatory effects to promote wound healing. The present study shows that JACE may help to increase the range of available treatments for wound-healing by reducing inflammation and oxidative stress

    Abstract Paracetamol is one of the drugs that cause hepatic damage. Fisetin has wide pharmacological effects such as anticancer, antiinflammatory and antioxidant. We aimed to evaluate the possible protective effect of fisetin on paracetamol-induced hepatotoxicity. Fisetin was administered at 25 and 50 mg/kg doses. Paracetamol was administered orally at a dose of 2 g/kg for induce hepatotoxicity 1 h after the fisetin and NAC treatments. The rats were sacrificed 24h after the Paracetamol administration. Tumor necrosis factor-alpha (TNF-α), NFκB and CYP2E1 mRNA levels and Superoxide dismutase (SOD) activity, glutathione (GSH) and malondialdehyde (MDA) levels of livers were determined. Serum ALT, AST and ALP levels were measured. Histopathological examinations were also performed. Fisetin administration significantly decreased the ALT, AST and ALP levels in a dose dependent manner. In addition, SOD activity and GSH levels increased, and the MDA level decreased with the treatment of fisetin. The TNF-α, NFκB and CYP2E1 gene expressions were significantly lower in both doses of the fisetin groups compared with the PARA group. Histopathological examinations showed that fisetin has hepatoprotective effects. This study showed that fisetin has the liver protective effects by increasing GSH, decreasing inflammatory mediators and CYP2E1

    WOS: 000454256900004In that study, it has been aimed to determine the effect of zinc and CoQ10 supplementation applied with 8-week swimming exercises on AST-ALT metabolism. Our study was conducted on 36 voluntary male athletes aged 18-22 who do physical exercises actively. The participants were divided equally into 4 groups. The groups were constituted in that way: 1st Group: Group which is supplied with zinc (Z), 2nd Group: Group which is supplied with Coenzyme Q10 (Q), 3rd Group: Control Group who does physical exercises (C) and 4th Group: Group which is supplied with Zinc and Coenzyme Q10 (ZQ). At the first week of the study, AST and ALT levels of the participants were measured from the samples which were drawn from the participants at pre-exercise resting period (PRP), post-exercise pre-test fatigue (PTF) and pre-exercise post-test rested (PTR) and post-exercise post-test fatigue (PTF) after 8-week supplementation period. In consequence of the conducted analysis, it was identified that rested AST levels of the group supplied with zinc were higher than their fatigue levels after 8-week supplementation period (p<0.05). As for ALT values of the group supplied with zinc, the post-test fatigue values were found lower than the pre-exercise rested and after 8-week exercise rested values (p<0.05). The post-test fatigue (PTF) values of the control group were determined lower than their post-test rested (PTR) values (p<0.05). It was identified statistically significant differences between not only PostTF and PostTR values but also PostTR and PreTR values of the group supplied with Zinc and Coenzyme Q10 (p<0.05). Consequently, it was confirmed that zinc and CoQ10 supplementation applied with 8-week swimming exercises had influence over the AST and ALT metabolism. It can be said that the antioxidant supplementation makes significant contributions as the AST and ALT metabolism are active

    This study aimed to investigate changes in postmortem urotensin II receptor (UTR) levels in brain and kidney tissues in a rat model of cardiac ischemia. The rats were divided into two groups: a control group and a cardiac ischemia-induced group. Cardiac ischemia was created by an intraperitoneal injection of a single lethal dose of isoproterenol (ISO; 850 mg/kg). Plasma UT, blood urea nitrogen, and creatinine levels were determined 0 h postmortem. Brain and kidney UTR mRNA expression levels were determined 0, 1, 3, 6, 12, 24, 48, and 72 h postmortem. The histopathological appearance of brain and kidney tissues was also evaluated. Plasma UT and plasma creatinine levels were increased in the cardiac ischemia-induced group as compared with those in the control group (P < 0.001). Ischemia resulted in histopathological changes in brain and cerebellum tissue. The morphological evaluation revealed Purkinje cell degeneration (P = 0.037) and dark neurons (P = 0.004). The UTR expression level decreased after 1 h postmortem in the brain and after 3 h postmortem in the kidneys in the cardiac ischemia-induced group as compared with that in the control group (P < 0.001). The observed changes in UTR expression levels may be valuable in clinical practice in the field of forensic medicine. These changes may be used as a marker in postmortem evaluations of sudden death caused by ischemia-induced cardiac shock

    The two main modalities used for congenital aortic valvular stenosis (AVS) treatment are balloon aortic valve dilatation (BAD) and surgical aortic valvuloplasty (SAV). This study evaluates residual and recurrent stenosis, aortic regurgitation (AR) development/progression, reintervention rates, and the risk factors associated with this end point in patients with non-critical congenital AVS who underwent BAD or SAV after up to 18years of follow-up. From 1990 to 2017, 70 consecutive interventions were performed in patients with AVS, and 61 were included in this study (33 BADs and 28 SAVs). There were no significant differences in age, sex distribution, PSIG, and AR frequency between the BAD and SAV groups. Bicuspid valve morphology was more common in the BAD group than the SAV group. There was no statistically significant difference between PSIGs and AR development or progression after intervention at the immediate postoperative echocardiography of patients who underwent BAD or SAV (p=0.82 vs. p=0.29). Patients were followed 6.9 +/- 5.1years after intervention. The follow-up period in the SAV group was longer than that of the BAD group (9.5 +/- 5.4 vs. 5.5 +/- 4.4 years, p=0.003). There was no statistically significant difference in the last echocardiographic PSIG between patients who underwent SAV or BAD (51.1 +/- 33.5 vs. 57.3 +/- 35.1, p=0.659). Freedom from reintervention was 81.3% at 5years and 57.5% at 10years in the BAD group and 95.5% at 5years and 81.8% at 10years in the SAV group, respectively (p=0.044). There was no difference in postprocedural immediate PSIG and last PSIG at follow-up and the development/progression of AR between patients who were treated with BAD versus SAV. However, long-term results of SAV were superior to those of BAD, with a somewhat prolonged reintervention interval

    We evaluated the natural course of congenital aortic valvular stenosis (AVS) and factors affecting AVS progression during long-term follow-up with echocardiography. Medical records of 388 patients with AVS were reviewed; patients with concomitant lesions other than aortic regurgitation (AR) were excluded. Trivial AVS was defined as a transvalvular Doppler peak systolic instantaneous gradient of 75mmHg. Median age of the patients was 3years (range 0day to 21years), and 287 (74%) were male. A total of 355 patients were followed with medical treatment alone for a median of 4.6years (range 1month to 20.6years), and the degree of AVS increased in 75 (21%) patients. The risk of AVS progression was higher when AVS was diagnosed in neonates (OR 4.29, CI 1.81-10.18, p=0.001) and infants (OR 3.79, CI 2.21-6.49, p=0.001). After the infancy period, bicuspid valve morphology increased AVS progression risk (OR 2.4, CI 1.2-4.6, p=0.034). Patients with moderate AVS were more likely to have AVS progression (OR 2.59, CI 1.3-5.1, p=0.006). Bicuspid valve morphology increased risk of AR development/progression (OR 1.77, CI 1.1-2.7, p=0.017). The patients with mild and moderate AVS were more likely to have AR development/progression (p=0.001). The risk of AR development/progression was higher in patients with AVS progression (OR 2.25, CI 1.33-3.81, p=0.002). Newborn babies and infants should be followed more frequently than older patients according to disease severity. Bicuspid aortic valve morphology and moderate stenosis are risk factors for the progression of AVS and AR

    Aim: The insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene is of increasing interest in etiology and treatment of various neuropsychiatric disorders. The present study aimed at detecting the incidence of ACE gene I/D polymorphism in patients with schizophrenia living in the Eskisehir region (Turkey) and also at determining whether this illness could be associated to ACE gene I/D polymorphism and serum ACE concentrations. Methods: In our study, genomic DNA was studied in a total of 237 individuals, 132 of them having been diagnosed as patients with schizophrenia and 105 of them being used as control subjects. In addition, sera from 31 patients with schizophrenia and 26 healthy subjects were used to compare serum ACE concentrations. By using polymerase chain reaction, we determined the frequency of ACE gene I/D polymorphism and measured the serum ACE concentrations by ELISA. Results and Conclusion: Distribution of ACE gene I/D polymorphism and allele frequencies between the control group genotype proportions (II 19%, ID 44%, DD 37%) and the patient group (II 19%, ID 45%, DD 36%) were not significantly different. Serum ACE concentrations were 293.15 +/- 23.29 ng/mL in the control group and 362.61 +/- 19.96 ng/mL in the patients. It was observed that serum ACE concentrations significantly increased in patients with schizophrenia compared with those of the control group (p < 0.05). However, no significant difference could be observed according to genotypes in serum ACE concentration

    Background: To evaluate the maternal serum amino acid levels in first trimester adolescent pregnancies by using a new developed dietary questionnaire. Methods: A group of 169 pregnant women in the first trimester of their pregnancy were asked to complete the dietary questionnaire. Among all the women, 39 were adolescent pregnancies. The results of the questionnaire were evaluated by a nutrient database program (BeBiS software program) designed to evaluate Turkish traditional foods and commercial processed foods. Results: There was no statistically significant difference between the groups in terms of body mass index and educational and socio-economic status. The mean age and gravidity was statistically significantly lower in adolescent pregnancies. The mean isoleucine, leucine, lysine, methionine, phenylalanine, tyrosine, threonine, valine, arginine, and proline levels were statistically significantly lower in adolescent pregnancies. Receiver operating characteristic (ROC) curve analysis showed the cut-off values of these amino acids. Of these amino acids; lower values of histidine, serine, and alanine were associated with lower birth weight, and lower values of histidine and alanine were associated with preterm delivery. Conclusion: To the best of our knowledge, this is the first study evaluating the amino acid levels in adolescent pregnancies. According to this study, some amino acid levels were lower in adolescent pregnancies and associated with adverse perinatal outcomes. Further studies with maternal and perinatal outcomes are needed to demonstrate the effects of these amino acids in such pregnancies
