Protective effect of citrus lemon on inflammation and adipokine levels in acrylamide-induced oxidative stress in rats

The high exposure to acrylamide (AA) due to smoking and increased consumption of processed and fast foods in recent years, has become one of the health threatening problems. This study examined the effect of lemon juice on inflammation and adipokines in acrylamide-induced oxidative stress in rats. Forty animals were divided into five groups. Toxicity was induced by AA (35mg/kg) for two weeks in all groups except normal control group. After that, lemon juice in three doses was administrated to treatment groups for 4 weeks. Serum levels of adipokines and inflammatory parameters and both serum and liver levels of oxidative stress parameters were measured. The results showed groups were received AA had significant higher levels of malondialdehyde, tumor necrosis factor alpha, leptin and C-reactive protein and lower levels of total antioxidant capacity compared to the negative control group. Lemon juice in all three doses significantly improved serum levels of TAC, MDA, TNFα and hs-CRP in treated groups. Also, 7.5 ml/kg lemon juice significantly decreased leptin levels. However, lemon juice had no significant effect on adiponectin levels. This study suggests lemon juice as a potential dietary alternative could attenuate leptin levels and manage oxidative and inflammatory damages in acrylamide- induced toxicity in rats

Fast but multi-partisan: Bursts of communication increase opinion diversity in the temporal Deffuant model

Human interactions create social networks forming the backbone of societies. Individuals adjust their opinions by exchanging information through social interactions. Two recurrent questions are whether social structures promote opinion polarisation or consensus in societies and whether polarisation can be avoided, particularly on social media. In this paper, we hypothesise that not only network structure but also the timings of social interactions regulate the emergence of opinion clusters. We devise a temporal version of the Deffuant opinion model where pairwise interactions follow temporal patterns and show that burstiness alone is sufficient to refrain from consensus and polarisation by promoting the reinforcement of local opinions. Individuals self-organise into a multi-partisan society due to network clustering, but the diversity of opinion clusters further increases with burstiness, particularly when individuals have low tolerance and prefer to adjust to similar peers. The emergent opinion landscape is well-balanced regarding clusters' size, with a small fraction of individuals converging to extreme opinions. We thus argue that polarisation is more likely to emerge in social media than offline social networks because of the relatively low social clustering observed online. Counter-intuitively, strengthening online social networks by increasing social redundancy may be a venue to reduce polarisation and promote opinion diversity.Comment: 9 pages, 6 figures.

Comparing endometrial hysteroscopic and histological findings of infertile women with polycystic ovary syndrome and unexplained infertility: A cross-sectional study

Background: Infertility is a critical condition in women with polycystic ovary syndrome (PCOS), caused not only by anovulation but also by endometrial abnormality. Objective: This study aimed to evaluate and compare the hysteroscopic and histological findings of endometrial biopsies in infertile women with PCOS and normal endometrial thickness and women with unexplained infertility (UI). Materials and Methods: This cross-sectional study compared the initial hysteroscopy and endometrial histological findings of 70 infertile women with PCOS and normal endometrial thickness with those of 35 women with UI. The relationship between endometrial histology and clinical parameters such as including luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone, testosterone, prolactin, fasting blood sugar, body mass index (BMI), and infertility duration was analyzed. Results: The mean age of women with PCOS was significantly lower than that of women with UI (27.5 ± 4.1 vs. 30 ± 4.5 years, respectively) (p < 0.001). The mean BMI was higher in women with PCOS than in women with UI (28.7 ± 4.4 vs. 25.1 ± 3 kg/m2) (p < 0.001). The hysteroscopic findings of all women with PCOS were normal, whereas 91.4% of women with UI had normal hysteroscopic findings, 2.9% had a polyp, and 5.7% had endometrial thickening. The histological findings of women with PCOS revealed proliferative endometrium in 54.3%, disordered proliferative endometrium in 17.1%, secretory endometrium in 8.6%, and endometrial polyp in 17.1%, whereas these percentages in women with UI were 28.6%, 0%, 54.3%, and 20%, respectively. Conclusion: The hysteroscopic evaluation alone of infertile women might not detect all probable endometrial pathologies in women with PCOS.

Self‐Esteem Mediates the Relationship between Emotional Intelligence and Life Satisfaction in Iranian Students

Background: It is demonstrated that students with better emotional intelligence (EI) had better self-esteem. The aim of study was to assess the role of self-esteem in the relationship of EI and LS. Methods: This cross-sectional study was done on 403 students of Shahroud University of medical sciences (northeast of Iran). In this study we used Schering Emotional Intelligence Questionnaire and Diener Satisfaction Questionnaire and Cooper Smith Self-Esteem Questionnaire. Mediation analyzes was done to assess the role of SE in the relationship of EI and LS. Results: About 82% of students had high emotional intelligence level. Comparison of the mean scores of EI, SE and LS by sex showed that there was no significant difference between gender means. The mean score of LS in the groups with high and moderate levels of EI score showed a significant difference between the life satisfaction score between two groups. The results of the mediation analysis showed that SE has a mediatorial role in the relationship between EI and LS, as 98% of the effect of emotional intelligence relationship is through mediating role of self-esteem. Conclusions: Self-esteem showed as an important mediator in the relationship of EI and LS. Regarding this valuable finding, better EI which results in better self-esteem and life satisfaction and these three items could separately results in a series of good results.
