زمینه و هدف: ریخت شخصیتی D (Distressed personality) حدود 21 جامعه سالم را تشکیل داده است و به عنوان یک ریسک فاکتور در بروزبیماری های قلبی-عروقی شناخته می شود. این تحقیق به منظوربررسی برخی ریسک فاکتورهای بروز بیماری های قلبی در افراد بزرگسال سالم دارای ویژگی ریخت شناسی D انجام شده است. روش بررسی: در این مطالعه توصیفی-تحلیلی 54 نفر (زن و مرد) از بین مراجعه کنندگان به مرکز آزمایشگاهی المهدی شهرکرد به روش نمونه گیری در دسترس انتخاب شدند. افراد تحت مطالعه بر اساس مقیاس DS14 به دو گروه تقسیم شدند. 27 نفر آنها که دارای تیپ شخصیتی D بودند در گروه مورد و 27 نفر دیگر که فاقد تیپ شخصیتی Dبودند در گروه شاهد قرار گرفتند. داده های پژوهش از طریق آزمون افسردگی بِک (Beck)، مقیاس های اضطراب و خشم اسپیلبرگر و نتایج آزمایشگاهی کلسترول، تری گلیسیرید،LDL و HDL جمع آوری شدند. برای تجزیه و تحلیل داده ها ازآزمون t مستقل استفاده شد. یافته ها: میزان اضطراب، افسردگی، خشم و LDL در گروه مورد به طور معنی داری بیشتر از گروه شاهد بود بود (05/0>P). میزان HDL بصورت جزئی در گروه مورد کمتر از گروه شاهد بود (052/0= P) و ارتباط معنی داری بین شخصیت D وکلسترول و تری گلیسیرید دیده نشد (05/

The Effects of Folic Acid Supplementation on Recurrence and Metabolic Status in Endometrial Hyperplasia: A Randomized, Double-Blind, Placebo-Controlled Trial

Abstract: Background: Data on the effects of folic acid supplementation on clinical symptoms and metabolic profiles of patients with endometrial hyperplasia (EH) are limited. This investigation was performed to evaluate the effects of folic acid supplementation on clinical symptoms and metabolic status of patients with EH. Methods: This randomized, double-blind, placebo-controlled trial was conducted among 60 women diagnosed with EH. Diagnosis of EH was made based on biopsy results. Participants were randomly allocated to 2 groups to take 5 mg/d folic acid supplements (n = 30) or placebo (n = 30) for 12 weeks. Results: After the 12-week intervention, folic acid supplementation significantly decreased fasting plasma glucose (β -3.99 mg/ dL; 95% CI, -7.39, -0.59; P = 0.02), serum insulin levels (β -2.82 µIU/mL; 95% CI, -4.86, -0.77; P = 0.008), homeostasis model assessment for insulin resistance (β -0.68; 95% CI, -1.20, -0.17; P = 0.009), triglycerides (β -16.47 mg/dL; 95% CI, -28.72, -4.22; P = 0.009) and very-low-density lipoprotein (VLDL) cholesterol (β -3.29 mg/dL; 95% CI, -5.74, -0.84; P = 0.009), and significantly increased the quantitative insulin sensitivity check index (β 0.01; 95% CI, 0.004, 0.03; P = 0.01) compared with the placebo. Additionally, folic acid intake resulted in a significant reduction in serum high sensitivity C-reactive protein (hs-CRP) (β -0.36 mg/L; 95% CI, -0.52, -0.21; P < 0.001) compared with the placebo. Folic acid supplementation did not affect other metabolic parameters. Conclusion: In conclusion, we found that folic acid administration for 12 weeks to subjects with EH improved glycemic control, triglycerides, VLDL-cholesterol and hs-CRP levels, but did not influence recurrence and other metabolic profiles

Beliefs and expectations about the future of personal life and future of the world in a sample of Iranian and Canadian students

This study was aimed to assess expectations about future of personal life and future of the world among a sample of Iranian and Canadian students. 60 Iranians from Tehran and Shahid Beheshti Universities in Iran and and 62 Canadians from Carleton University in Canada completed a researcher made questionnaire asking their beliefs and expectations in four areas such as personal future, generational comparison, future of the world and personal life goals. The results showed that both Iranian and Canadian participants were more optimistic about their personal future than about the future of the world but Iranians were less optimistic about the future of the world than were Canadians. Both groups expect to be richer and have a higher quality of life than their parents, and both expect their children to have a lower quality of life than their parents and to be poorer than themselves. Cultural differences were found in the importance Iranians and Canadians attach to life goals. Results and implications are discussed

Association of food allergies, cow�s milk allergy, and asthma with pediatric inflammatory bowel disease

There are controversies on the association of childhood allergic diseases with inflammatory bowel diseases (IBD). The aim of this study was to examine the association between food allergy, cow�s milk allergy (CMA), and asthma with pediatric IBD in Iranian population. This case-control study was conducted on 200 individuals less than 18-year-old (100 with IBD and 100 as control group). Medical records, clinical presentation, and laboratory and para-clinical findings related to food allergy, CMA, and asthma were reviewed for all participants in both groups and were recorded. Among 100 children with IBD, 40 had Crohn's disease, and 60 had ulcerative colitis. The frequency of food allergy, cow's milk allergy, and asthma in children with IBD was significantly higher than the control group (P<0.001). Asthma in children with Crohn's disease was significantly more prevalent than children with ulcerative colitis (P=0.008). Food allergy (OR: 22.1, 95 CI: 5.1-95.05, P<0.001), CMA (OR: 15, 95 CI: 3-67, P<0.001), and asthma (OR: 10, 95 CI: 3-37.05, P<0.001) were significantly associated with increased risk of IBD in children. Food allergy, CMA in infancy and asthma are more prevalent in children with different subtypes of IBD. The diagnosis of these risk factors is associated with increased risk of Crohn's disease and ulcerative colitis. © 2018 Tehran University of Medical Sciences. All rights reserved

Molecular genetic diagnosis of Glanzmann syndrome in Iranian population; Reporting novel and recurrent mutations

Background: Glanzmann thrombasthenia (GT) is a rare autosomal recessive abnormality of platelet aggregation with quantitative and/or qualitative abnormality of αIIbβ3 integrin. The αIIbβ3 is a platelet fibrinogen receptor, which is required for platelet aggregation, firm adhesion, and also spreading. The disease is more prevalent in the populations with a higher rate of consanguineous marriages as in some Middle Eastern populations including Iraq, Jordan, and Iran. Different types of mutations in ITGA2B and ITGB3 genes have been previously reported to cause the disease. Result: In this study, 16 patients with the clinical diagnosis of GT were studied. Direct sequencing of the exons and exon-intron boundaries of the above genes revealed mutations in 14 patients (detection rate: 87.5). Briefly, out of fifteen types of identified mutations, 14 were novel. Seven mutations in the ITGB3 gene included 4 missense c.2T > C, c.155 G > T, c. 538 G > A, c.1990 G > T, one nonsense mutation c.1303 G > T, a small deletion c.1656-1658delCTC and a deletion of one nucleotide c.401delA. Mutations in the ITGA2B were 8 different mutations consisting 2 missense c.286 T > A, c.842 C > T, 2 deletions c.1899 del T, c.189-319-236del, an insertion c.1071-1072insG and one splice site mutations c.409-3 C > G, one synonymous mutation that might alter the normal splicing process c.1392 A > G and a nonsense mutation c.1555 C > T. The causative mutation in 2 patients remained unknown. Using long-range PCR and sequencing, we found a rather large deletion. The break point of this deletion covers 319 nt from the last part of the first intron and 48 nt from the beginning of the second exon of ITGA2B gene. The deletion was also detected in two unrelated patients with the same ethnicity. In addition, in silico analyses of novel mutations were performed. Conclusion: There was no recurrent mutation in the studied population. This may be due to either small sample size or the heterogeneity of the studied population. © 2019 The Author(s)

Root canal morphology of primary maxillary second molars:a micro-computed tomography analysis

Aim Successful endodontic treatment of primary teeth requires comprehensive knowledge and understanding of root canal morphology. The purpose of this study was to investigate the root canal configurations of primary maxillary second molars using micro-computed tomography. Methods Extracted human primary maxillary second molars (n = 57) were scanned using micro-computed tomography and reconstructed to produce three-dimensional models. Each root canal system was analysed qualitatively according to Vertucci's classification. Results 22.8% (n = 13) of the sample presented with the fusion of the disto-buccal and palatal roots; of these, Type V was the most prevalent classification. For teeth with three separate roots (n = 44), the most common root canal type was Type 1 for the palatal canal (100%) and disto-buccal canal (77.3%) and Type V for the mesio-buccal canal (36.4%). Overall, 7% (n = 4) of mesio-buccal canals were 'unclassifiable'. Conclusion The root canal systems of primary maxillary second molars were not only complex but had a range of configurations that may contribute to unfavourable clinical outcomes after endodontic treatment

Perceptions of the appropriate response to norm violation in 57 societies

Norm enforcement may be important for resolving conflicts and promoting cooperation. However, little is known about how preferred responses to norm violations vary across cultures and across domains. In a preregistered study of 57 countries (using convenience samples of 22,863 students and non-students), we measured perceptions of the appropriateness of various responses to a violation of a cooperative norm and to atypical social behaviors. Our findings highlight both cultural universals and cultural variation. We find a universal negative relation between appropriateness ratings of norm violations and appropriateness ratings of responses in the form of confrontation, social ostracism and gossip. Moreover, we find the country variation in the appropriateness of sanctions to be consistent across different norm violations but not across different sanctions. Specifically, in those countries where use of physical confrontation and social ostracism is rated as less appropriate, gossip is rated as more appropriate.info:eu-repo/semantics/publishedVersio

Anger and disgust shape judgments of social sanctions across cultures, especially in high individual autonomy societies

Data availability; The datasets analyzed during the current study are available in the Center for Open Science repository, https://osf.io/djnfg/.Supplementary Information is available online at: https://link.springer.com/article/10.1038/s41598-024-55815-x#Sec17 .When someone violates a social norm, others may think that some sanction would be appropriate. We examine how the experience of emotions like anger and disgust relate to the judged appropriateness of sanctions, in a pre-registered analysis of data from a large-scale study in 56 societies. Across the world, we find that individuals who experience anger and disgust over a norm violation are more likely to endorse confrontation, ostracism and, to a smaller extent, gossip. Moreover, we find that the experience of anger is consistently the strongest predictor of judgments of confrontation, compared to other emotions. Although the link between state-based emotions and judgments may seem universal, its strength varies across countries. Aligned with theoretical predictions, this link is stronger in societies, and among individuals, that place higher value on individual autonomy. Thus, autonomy values may increase the role that emotions play in guiding judgments of social sanctions.This research was funded by the Swedish Foundation for Humanities and Social Sciences (Riksbankens Jubileumsfond) [P17-0030:1].

Valorisation of Biowastes for the Production of Green Materials Using Chemical Methods

With crude oil reserves dwindling, the hunt for a sustainable alternative feedstock for fuels and materials for our society continues to expand. The biorefinery concept has enjoyed both a surge in popularity and also vocal opposition to the idea of diverting food-grade land and crops for this purpose. The idea of using the inevitable wastes arising from biomass processing, particularly farming and food production, is, therefore, gaining more attention as the feedstock for the biorefinery. For the three main components of biomass—carbohydrates, lipids, and proteins—there are long-established processes for using some of these by-products. However, the recent advances in chemical technologies are expanding both the feedstocks available for processing and the products that be obtained. Herein, this review presents some of the more recent developments in processing these molecules for green materials, as well as case studies that bring these technologies and materials together into final products for applied usage
