Objective
Assessing the risk levels of patients with acute ischemic stroke (AIS) can assist in making informed choices about their treatment and rehabilitation. To assess the prognostic value of serum insulin-like growth factor-1 (IGF-1) in neurological deficit (National Institutes of Health Stroke Scale [NIHSS]), functional independence (Modified Rankin Scale [mRS]), and mortality following AIS.
MethodsThe search encompassed Medline, Embase, Scopus, and Web of Science until June 2023. Two autonomous researchers incorporated articles by the established inclusion and exclusion criteria. The quality of the included studies were assessed using the quality assessment of prognostic accuracy studies (QUAPAS) tool.
ResultsTen articles were included, with evidence suggesting that IGF-1 may have prognostic value in AIS outcomes. Several studies reported positive associations between IGF-1 levels, reduced neurological deficits, improved functional independence, and lower mortality. Additionally, intraindividual fluctuations in IGF-1 after AIS were identified as a potential predictor of recovery in functional independence, though significant inconsistencies exist in the findings.
ConclusionThe available studies with a very low level of evidence are not sufficient to firmly endorse the applicability of IGF-1 as a prognostic factor for mortality, neurological disability, and functional independence.

از آن جا که یکی از مهم ترین سوانح کشور ایران، تصادفات جاده ای بوده و بیشترین علل بروز حوادث و سوانح ترافیکی مربوط به عامل انسان و هوش فرهنگی است، هدف این پژوهش، ارائه مدلی برای بهبود ایمنی راه و کاهش تصادفات، با تاکید بر عامل انسانی و فرهنگ ایمنی است. در این پژوهش توصیفی-تحلیلی با جامعه آماری 50 نفر از مردم عادی و 50 نفر از پلیس راهور از رهگذر نمونه گیری تصادفی ساده، داده های موردنیاز از دو روش پیمایشی و کتابخانه ای به دست آمده است. تجزیه و تحلیل پرسشنامه ها به وسیله نرم افزار minitab17 انجام گرفت. یافته ها نشان داد که بین هوش فرهنگی با فرهنگ کشورها در کاهش تصادفات، بین اتخاذ سیاست آسان گیرانه در مقابل تخلفات رانندگی در جامعه و کاهش تصادفات، بین رسانه ها و مدارس با کاهش تصادفات و ارتقاء فرهنگ و بین بهبود در فرهنگ استفاده از وسایل حمل ونقل عمومی با کاهش تصادفات رابطه معنادار وجود دارد. به علاوه، نتایج تحلیلی رابطه ای معکوس و معنادار را بین هوش فرهنگی از تخلف رانندگی نشان می دهد؛ به گونه ای که با افزایش و تقویت هوش فرهنگی و آگاهی ترافیکی مردم، تصادفات کاهش خواهند یافت.
کلید واژگان: تصادف، هوش فرهنگی، ترافیک، فرهنگ ایمنیSince one of the most important accidents in Iran is road accidents and most of the causes of traffic accidents and incidents are related to the human factor and cultural intelligence, the aim of this study is to present a model for improving road safety and reducing accidents, with an emphasis on the human factor and safety culture. In this descriptive-analytical study with a statistical population of 50 ordinary people and 50 traffic police officers through simple random sampling, the required data were obtained through two survey and library methods. The questionnaires were analyzed using Minitab17 software. The findings indicated that there is a significant relationship between cultural intelligence and the culture of countries in reducing accidents, between adopting a lenient policy against traffic violations in society and reducing accidents, between the media and schools with reducing accidents and promoting culture, and between improving the culture of using public transportation with reducing accidents. In addition, the analytical results show an inverse and significant relationship between cultural intelligence and traffic violations; in such a way that by increasing and strengthening cultural intelligence and traffic awareness of people, accidents will be reduced.

Cisplatin resistance presents a considerable hurdle in the treatment of ovarian cancer, significantly impacting patient outcomes and limiting the effectiveness of chemotherapy. This study employs advanced bioinformatics techniques-including RNA sequencing (RNA-seq), DNA sequencing (DNA-seq), and chromatin immunoprecipitation sequencing (ChIP-seq)-to elucidate the molecular mechanisms underlying this resistance, with a particular focus on the long non-coding RNA (lncRNA) LINC02381. Our findings reveal that LINC02381 is significantly upregulated in ovarian cancer cells exhibiting resistance to cisplatin, suggesting its pivotal role in mediating this phenomenon. We further demonstrate that cytokines, particularly interleukin-12 (IL-12), secreted by immune cells within the tumor microenvironment, activate the Wnt signaling pathway. This activation leads to the binding of the transcription factor TCF7 to the promoter region of LINC02381, resulting in enhanced expression of this lncRNA. Notably, this interaction establishes a positive feedback loop in which LINC02381 not only promotes its own expression but also amplifies Wnt signaling activity. This cascade ultimately drives the upregulation of ATP-binding cassette (ABC) transporters, which are crucial for the efflux of cisplatin from cancer cells. Thus, the drug's intracellular concentration is reduced, and cell survival under chemotherapy pressure is facilitated. These insights uncover a novel mechanism of cisplatin resistance driven by the IL-12/Wnt/TCF7/LINC02381 axis, highlighting the complex interplay between immune signaling and drug resistance in ovarian cancer. Our findings suggest that targeting this regulatory pathway may offer promising therapeutic strategies to overcome chemotherapy resistance, paving the way for improved treatment outcomes in patients with ovarian cancer. Future research should focus on validating these mechanisms and exploring potential interventions that disrupt this feedback loop.

The present paper deals with the historical overview and the reception of William Shakespeare’s Sonnets in contemporary Iran. The authors examine the chronology of Persian translations of Shakespeare’s Sonnets (both scattered and book-length ones) during a century which is a considerable period of time in the examination of the reception of any author in another culture. As poetry is not the most popular genre in Persian translation, the Persian translations of William Shakespeare’s Sonnets suffered from a lot of fluctuations. It was in the latter part of the nineteenth century, a turning-point in the history of the country, that Shakespeare was introduced into Iranian audience for the first time. It started with scattered translations and ended in book-length ones. This study indicates early Persian interest in Shakespeare’s Sonnets which was followed by a lull. The reason behind it was two-fold: the translation of foreign poetry was dominated by French and Russian languages, and the rich tradition of Persian poetry does not feel the need to translate foreign poetry. The reception of Shakespeare’s Sonnets was followed by renewed interest in 1998-2017 and finally book-length translations began to thrive. All in all, Shakespeare’s Sonnets did not have a great influence on Persian poetry, as it was expected.

بررسی تشابه مضمونی و تاثیر و تاثر شاعران و نویسندگان از/ بر یکدیگر ضرورت دارد چرا که به درک بهتر آثار آنان کمک می کند. این پژوهش، از رهگذر فولکلور تطبیقی، به بررسی مشابهت مضمونی شعری از سعدی و داستانی از بوکاچو می پردازد و به پرسش های زیر پاسخ می دهد: آیا مشابهت مضمونی میان شعر «اسب تازی نهاد» سعدی و داستان «باز شکاری» از مقوله توارد و تشابه است، یا از مقوله تاثیر و تاثر؟ آیا این تشابه مضمونی از مقوله «قصه های سرگردان» یا «قصه های بین المللی» است؟ آیا احتمال دارد هر دو از یک منبع مشترک متاثر باشند؟ به علت وجود قرب تاریخی جغرافیایی، و وجود وسایل و طرق مشخص نقل و انتقال (مانند جنگ های صلیبی، اسپانیای سده های میانه، و تجارت با کشورهای خاور نزدیک) حکایت «اسب تازی نهاد» سعدی و داستان «باز شکاری» بوکاچو بر خلاف مشابهت مضمونی نه از مقوله توارد و تشابه بل از مقوله تاثیر و تاثر است و تصور اخذ و اقتباس مستقیم این دو داستان از یکدیگر بعید و آشنایی بوکاچو با داستان سعدی و حتی عوفی، مقدم بر سعدی، نامحتمل است. به علاوه، به خاطر شباهت های زیاد در جزئیات، در مشابهت مایگانی و در ترتیب و توالی دو داستان، شاید بتوان دو داستان را دو روایت از یک نوع داستان دانست که هر دو داستان از یک اصل منشعب شده اند. به احتمال زیاد روایت شفاهی یا کتبی اصل عربی این داستان به وسیله صلیبی ها و از رهگذر زبان لاتین به عنوان زبان میانجی به اروپا راه یافته و بوکاچو از آن متاثر شده است
کلید واژگان: مشابهت مضمونی، سعدی، بوکاچو، قصه های سرگردان، ادبیات تطبیقیThe study of thematic similarities and influence of authors on each other is necessary because it helps us to understand their works much better. This paper, through the prism of comparative folklore, deals with thematic similarities between a poem from Sa’di and a story from Boccaccio, and answers the following questions: Can we consider the thematic similarity between Sa’di’s “The Arab Horse” and Boccaccio’s “The Falcon of Federigo” as an example of similarity or influence studies? Can it be regarded as an example of “International Tales”? Is it possible that they have a common source? Because of the historical-geographical closeness and the nexus of transmission (such as the Crusades, medieval Spain, or trade with the Levantine countries) Sa’di’s “The Arab Horse” and Boccaccio’s “The Falcon of Federigo”, unlike thematic similarities, can be regarded as an example of influence studies. Also, it cannot be regarded a kind of direct adaptation. In addition, Boccaccio’s familiarity with Sa’di’s poem, and even Ufi’s anecdote, is impossible. The two stories, possibly, are two different narratives of a “tale type” because they share great similarities in themes and the order of the events, so they may have one common source. In all possibilities, an original Arab oral or written narrative of the story went to Europe by Crusaders or through the Latin, as a lingua franca, and finally influenced Boccaccio.

از زمانی که سر ویلیام جونز در سال 1771 برای نخستین بار غزلی از حافظ را به انگلیسی هم به نثر و هم به نظم ترجمه کرد بیش از 250 سال میگذرد. در این مدت نسبتا بلند، مترجمان مختلف در ادوار مختلف قالب نثر، نظم و ترجمه خلاقانه را برای برگردان تمام یا گزیدهای از غزلیات حافظ برگزیدهاند. از آن میان ترجمه به نظم خواه در قالب شعر عروضی خواه شعر آزاد پرکاربردترین قالب بوده است. با این همه، ترجمههای اندکشماری توانستهاند تا حدودی ظرایف و طرایف صوری و معنایی شعر حافظ را به انگلیسی منتقل کنند. یکی از این ترجمهها اشعاری از دیوان حافظ (1897) به قلم گرترود بل است. متخصصان، ایرانی و انیرانی، این ترجمه را از معدود ترجمههای موفق و مقبول از شعر حافظ به انگلیسی دانستهاند. ترجمه بل را باید ترجمهای نسبتا آزادی از غزلیات حافظ به شمار آورد. این ترجمه مشتمل بر 42 غزل و یک قطعه است. به علاوه، بل «مقدمه»ای مبسوط و «تعلیقاتی» سودمند بدین ترجمه افزوده است. مستشرقان بزرگی، ازجمله ادوارد براون، این «مقدمه» را یکی از بهترین و پراطلاعترین نوشتهها به انگلیسی درباره حافظ و عصرش میدانند. با این همه، در این «مقدمه» سهوهایی عمدتا تاریخی به چشم میخورد. مقاله حاضر بر آن بوده که ابتدا این سهوهای تاریخی (و بعضا غیرتاریخی) را مشخص و براساس منابع تاریخی معتبر عصر حافظ اصلاح کند. مهمتر اینکه، با مستندات نشان دهد که این سهوهای تاریخی (و بعضا غیرتاریخی) از چه منبع یا منابعی به «مقدمه» بل راه یافته است.
کلید واژگان: اشعاری از دیوان حافظ، گرترود بل، حافظ، ترجمه، مقدمه، سهوهای تاریخیOver two hundred and fifty years ago, Sir William Jones first translated a ghazal by Hafiz into English, both in prose and verse. Since then, various translators have employed prose, verse, and creative translations to render Hafiz’s poems, either in full or in part. Among these, verse translation—whether in prosodic or non-prosodic poetry—has been the most prevalent. However, only a few translations have successfully conveyed the formal and thematic subtleties of Hafiz’s ghazals. One notable example is Gertrude Bell’s 1897 work, Poems from the Divan of Hafiz. This translation, which includes forty-two ghazals and an additional piece, is widely regarded by both Iranian and non-Iranian specialists as one of the most successful and acclaimed translations of Hafiz’s poetry. Bell’s translation is considered a somewhat free rendition of Hafiz’s ghazals and is complemented by an Introduction and Notes. Esteemed orientalists, including Edward Brown, have praised the Introduction as one of the most informative English writings on Hafiz and his era. However, this Introduction contains several historical inaccuracies. This paper aims to identify and correct these historical errors using authentic historical sources related to Hafiz’s time. Furthermore, it seeks to demonstrate, with evidence, the origins and pathways of these inaccuracies in Bell’s Introduction.

Background
The available evidence suggests that urinary calprotectin may be a potential biomarker in distinguishing between intrinsic acute kidney injury (AKI) and prerenal AKI.
ObjectivesThe aim of this study was to determine the diagnostic value of calprotectin in identifying pediatric acute renal impairment.
MethodsA search of the Medline, Embase, Scopus and Web of Science electronic databases was conducted on April 27, 2024. Diagnostic studies conducted on the value of urinary calprotectin in AKI were included. Two independent reviewers assessed the search records and any disagreements were resolved by discussion. The risk of bias was assessed using quality assessment of diagnostic accuracy studies (QUADAS-2) guidelines. The performance of urinary calprotectin in diagnosing AKI and its discriminatory ability between intrinsic and prerenal AKI were evaluated by calculating the pooled standardized mean difference (SMD) and 95% confidence interval (CI), as well as sensitivity, specificity and area under the curve (AUC).
ResultsSeven studies were included. The mean urinary levels of calprotectin in AKI were significantly higher than those in the non-AKI group (SMD=0.73; 95% CI, 0.50%, 0.97%; I2=0.00%). The mean urinary levels of calprotectin in pediatrics with intrinsic AKI were significantly higher than in those with prerenal AKI (SMD=0.76; 95% CI, 0.48%, 1.05%; 95% CI, 0%). Urinary calprotectin exhibited a sensitivity of 0.937 (95% CI, 0.829%, 0.978%) and a specificity of 0.252 (95% CI, 0.126%, 0.442%) for distinguishing intrinsic AKI from prerenal AKI. Additionally, the AUC of urinary calprotectin in differentiating intrinsic AKI from prerenal AKI was 0.691 (95% CI, 0.541%, 0.809%).
ConclusionsUrinary calprotectin demonstrates fair screening performance characteristics for differentiating intrinsic from prerenal AKI in children. However, the low specificity necessitates additional diagnostic testing in cases with positive results.

It can be used for dry forage, pasture, silage, seed production and human nutrition (Lee et al., 2004). American agricultural department also recommend different fodder beets cultivars to the farmers who seek the cultivation of forages with high economic and biological performance in dry and semi dry areas of this country (Fasahat et al., 2019) . Due to its high production potential, optimum nutritional value, and the ability to be preserved as a dry hay and silage, fodder beet can be grown in many areas of Iran with different climate conditions for forage production (Taleghani et al., 2020). But, these findings need to be refined, improved and tested for local climatic, soil and crop conditions. The aim of this experiment was to determine the best cultivar from compairing of morphological and yield of two cultivars in autumn cultivation of fodder beet in Kordkuy and Bandar Torkman regions.
Materials and MethodsThis research was conducted in Golestan province during the 2021-2022 growing season. This research performed in Kordkoy and Bandar-Torkeman. Experiments consisted of two fodder beet (Beta vulgaris L.), The number of planting lines was 100 with a length of 100 meters and 50 cm interval between the lines. To measure traits 10 bushes were randomly harvested by using quadrate. The total surface area under cultivation was measured. To find crop production of fodder beet cultivars the results were compared using t-test.
Results and DiscussionThe mean comparison of yield and morphological parameters of two new fodder beet varieties (Beta vulgaris L.) showed that Kara, new fodder beet variety in Kordkuy had a plant height of 139.94 cm, which was 51.19% taller than Timbale cultivar. Timbale produced greater root diameter (13.1 mm) root length and number of leaf (45.05) compared to Kara cultivar. The mean comparison of fresh yield of two fodder beet varieties showed significant differences among the varieties. Fresh forage production of Timbale with a yield of 182.96 ton ha-1 was 48.02% greater compared to Kara cultivar, which gave a yield of 87.86 ton ha-1. The mean comparison of dry yield showed significant differences among the varieties. Dry forage production of Timbale (22.25 ton ha-1) was 43.68% higher than the Kara cultivar, which produced a dry forage yield of 12.53 ton ha-1). Also, the fodder beet varieties of Timbale was superior in terms of morphological parameters as compared to the Kara cultivar. Forage beet cultivation in the country so far has been based on the use of seeds of local mass and only Kara cultivar has been introduced as the first forage cultivar in Iran, which needs to be improved to achieve new cultivars (Taleghani et al., 2020). It indicates that the new fodder beet plants grow better and produce higher yield components.
ConclusionOverall, the findings of the study showed that Timbale variety performed better relative to Kara. The fresh forage and dry forage production of the new variety (Timbale ) were greater than Kara cultivar. It could be concluded that, by using new fodder beet variety during autumn cropping season, higher yield per surface area might be attained.

Background
Identifying affecting and predictive factors of steroid-sensitive nephrotic syndrome’s (SSNS's) outcome may greatly benefit the proper management of SSNS patients.
ObjectivesThe current systematic review comprehensively reviews all available evidence on the risk factors of SSNS relapse in children and adolescents.
MethodsAn extensive search was conducted on the electronic databases of Medline, Embase, Web of Science, and Scopus until February 18, 2024. Studies investigating the risk factors of relapse were included in this systematic review.
ResultsA total of 11 articles were included. Age, gender, and laboratory variables, such as serum creatinine and serum protein are not risk factors for relapse in these studies. Possible associations were reported for risk factors, such as the number of relapses and response time. Overall, the studies reported conflicting results on the value of relapse risk factors.
ConclusionsAlthough factors, such as hematuria, hypertension, time from treatment to response, and number of relapses have been proposed as possible risk factors for relapse, no conclusion can be reached due to the heterogeneity of studies. Future studies should have more conforming designs to make comparisons more reliable.

هدف
اصلی این پژوهش، طراحی چارچوب دانشگاه استعداد ربا در نظام آموزش عالی است.
روش شناسی:
این پژوهش از نوع کاربردی، در زمره پژوهش های با رویکرد سنتز پژوهی و از نوع فراترکیب کیفی است. این روش، یک موقعیت سه جانبه از تحلیل داده ها، نظریه ها و روش شناسی پژوهش هاست و بسیار فراتر از خلاصه سازی یافته های پژوهشی و درواقع ترکیب و تفسیر یکپارچه ی یافته های حاصل از مطالعات کیفی است به گونه ای که تصویری کلی از وقایع، مفاهیم و پدیده ها ایجاد کند و با استفاده از روش هفت مرحله ای ساندلوسکی و باروسو انجام شده است.
یافته هاتجزیه وتحلیل داده ها با استفاده از روش تحلیل مضمون صورت پذیرفت. مضامین شناسایی شده مجددا در جلسه بحث گروهی متمرکز با استفاده از شبکه اجتماعی مجازی موردبررسی قرار گرفتند تا درنهایت روی مقولات استخراج شده توافق حاصل گردید. تمام عوامل استخراج شده از پژوهش ها به عنوان مضمون در نظر گرفته شد که این مضامین بر اساس مفاهیم مرتبط با مفهوم دانشگاه استعداد ربا در 41 مضمون پایه و 9 مضمون سازمان دهنده طبقه بندی شدند.
نتیجه گیری و پیشنهاد ها: بر اساس یافته های پژوهش می توان به ویژگی های خاصی از دانشگاه های استعداد ربا پی برد که آنان را برای اعضای هیئت علمی و دانشجویان با استعداد جذاب و خواستنی می نماید. این ویژگی ها فراتر از ویژگی های ساختاری و تجهیزاتی و مالی آنان که شاید بتوان در اکثر دانشگاه های مادر و جامع یافت، بر ویژگی هایی تاکید دارد که شاید در اکثر دانشگاه ها به فراموشی سپرده شده است. این دانشگاه های استعدادربا، برای اعضای هیئت علمی و دانشجویان با استعداد، آرامش فکری و روحی، احساس بهزیستی سازمانی و رضایت قلبی و درونی را به ارمغان می آورند و بنابراین می توانند ورای اندازه و محل جغرافیایی یک دانشگاه، آن را تبدیل به یک دانشگاه استعداد ربا نماید.نوآوری و اصالت:
شاید بتوان گفت که پژوهش های انجام شده در حوزه ارزیابی درونی و بیرونی و مدیریت استعداد در آموزش عالی در ایران و خارج از کشور، بیشتر بر شیوه ها و تکنیک ها و راهبردهایی متمرکز شده اند که برای جذب و نگهداری اعضای هیئت علمی و دانشجویان با استعداد لازم است، اما پژوهش حاضر حرکت از نقش محوری دانشگاه ها در یافتن و جذب و نگهداشت اعضای هیئت علمی و دانشجویان با استعداد با در نظر گرفتن امتیازات و یا جوایز خاص، به تمرکز بر ویژگی های جذاب دانشگاه ها رسیده است که باعث می شود دانشجویان و اعضای هیئت علمی با استعداد بدون امتیازدهی خاصی برای رسیدن به این دانشگاه ها با هم رقابت نمایند.
کلید واژگان: استعداد ربایی، آموزش عالی، اعضای هیئت علمی، فراترکیبPurposeThe main purpose of this research is to design the framework of talent-grabbing university in the higher education system.
MethodologyThe present research is qualitative and of meta-synthesis type. This method is a tripartite situation of data analysis, theories and research methodology and goes far beyond the summarization of research findings. In fact, it is the integrated synthesis and interpretation of findings from qualitative studies in such a way that it provides a general picture of events, concepts and phenomena which has been done using the seven-step method of Sandelowski and Barroso.
FindingsData analysis was done using the thematic analysis method. Identified themes were re-examined in a focus group discussion session using a virtual social network to reach an agreement on the extracted categories. All the factors extracted from the researches were considered as themes, and these themes were classified into 41 basic themes and 9 organizing themes based on the concepts related to the concept of talent-grabbing university.
Conclusions and suggestions:
Based on the findings of the research, it is possible to understand the special characteristics of talent-grabbing universities that make them attractive and desirable for faculty members and talented students. These features, beyond theirstructural, equipment and financial features that can be found in most of the mother and comprehensive universities, emphasize the features that have been forgotten in most of the universities. These talent-grabbing universities bring mental and spiritual peace, goodness and heart and inner satisfaction to faculty members and talented students. Therefore, beyond the size and geographical location of the university, they can turn it into a talent-grabbing university.
Innovation and originality:
It can be said that the researches carried out in the field of internal and external evaluation and talent management in higher education in Iran and abroad are more focused on methods, techniques and strategies to attract and retain talented faculty members and students. It is necessary, but the present research moves from the central role of universities in finding and attracting and keeping faculty members and talented students, taking into account special privileges or awards. It has come to focus on the attractive characteristics of universities that make talented students and faculty members compete to get to these universities without special points.

Introduction
Quantile regression is a valuable alternative for survival data analysis, enabling flexible evaluations of covariate effects on survival outcomes with intuitive interpretations. It offers practical computation and reliability. However, challenges arise when applying quantile regression to censored data, particularly for upper quantiles. The minimum distance approach, utilizing dual-kernel estimation and the inverse cumulative distribution function, shows promise in addressing these challenges, especially with higher-dimensional covariates.
MethodsThis study contrasts two methods within the realm of quantile linear regression for survival analysis: check-based modeling and the minimum distance approach. Effectiveness is assessed across various scenarios through comprehensive simulation.
ResultsThe simulation results showed that using the quantile regression model with the minimum distance approach reduces the percentage of root mean square error in parameter estimation compared to the quantile regression models based on the check loss function. Additionally, a larger sample size and reduced censoring percentage led to decreased root mean square error in parameter estimation.
ConclusionThe research highlights the benefits of using the minimum distance approach for quantile regression. It reduces errors, improves model predictions, captures patterns, and optimizes parameters even with complete data. However, this approach has limitations. The accuracy of estimated quantiles can be influenced by the choice of distance metric and weighting scheme. The assumption of independence between censoring mechanism and survival time may not hold in real-world scenarios. Additionally, dealing with large datasets can be computationally complex.

Introduction
Ignoring outliers in data may lead to misleading results. Length of stay (LOS) is often considered a count variable with a high frequency of outliers. This study exemplifies the potential of robust methodologies in enhancing the accuracy and reliability of analyses conducted on skewed and outlier-prone count data of LOS.
MethodsThe application of Zero-Inflated Poisson (ZIP) and robust Zero-Inflated Poisson (RZIP) models in solving challenges posed by outlier LOS data were evaluated. The ZIP model incorporates two components, tackling excess zeros with a zeroinflation component and modeling positive counts with a Poisson component. The RZIP model introduces the Robust Expectation-Solution (RES) algorithm to enhance parameter estimation and address the impact of outliers on the model’s performance.
ResultsData from 254 intensive care unit patients were analyzed (62.2% male). Patients aged 65 or older accounted for 58.3% of the sample. Notably, 38.6% of patients exhibited zero LOS. The overall mean LOS was 5.89 (± 9.81) days, and 9.45% of cases displayed outliers. Our analysis using the RZIP model revealed significant predictors of LOS, including age, underlying comorbidities (p<0.001), and insurance status (p=0.013). Model comparison demonstrated the RZIP model’s superiority over ZIP, as evidenced by lower Akaike information criteria (AIC) and Bayesians information criteria (BIC) values.
ConclusionThe application of the RZIP model allowed us to uncover meaningful insights into the factors influencing LOS, paving the way for more informed decision-making in hospital management.

Introduction
The effectiveness of various extrinsic and intrinsic regulatory signals on food intake and body weight can be influenced by hypothalamic neuropeptide-Y (NPY) and proopiomelanocortin (POMC) neurons. While several studies emphasize the vital role of regular physical activity in effective weight management, how these molecular and cellular processes interact with physical activity remains an area in need of further exploration. Hence, this study aims to investigate the impact of various long-term physical activities intensities on the regulation of body weight and appetite.
MethodsTwenty-one Wistar rats (n=7) were randomized into three groups: 1) Control group, 2) a group engaged in regular exercise at moderate intensity for 24 weeks (24-ME, 5 days each week), and 3) a group frequently and intensively exercising over 24 weeks (24-IE, 5 days each week). Subsequently, Reverse transcription polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA) methods were performed to measure gene expression of hypothalamic arcuate nucleus NPY and POMC, as well as serum levels of acyl-ghrelin and leptin.
ResultsThe POMC mRNA level decreased in the 24-ME group compared to the control rats. However, intensive regular exercise increased NPY expression compared to the control rats. Inversely, body weight and food intake levels were considerably higher in the 24-ME and 24-IE groups than in the control group. Different intensities of prolonged exercise seem to heighten appetite, eventually increasing body weight through distinct molecular pathways.
ConclusionHence, it can be concluded that prolonged intensive exercise may not be a practical approach for weight loss.

The famous German poet, novelist and dramatist, Johann Wolfgang von Goethe, from his early youth was somehow interested to the East, in the inclusive sense of the word, and regularly read the books, in different European national languages, on East and its people. While reading these miscellaneous books that he became acquainted with Muslims’ religious book, the Holy Quran, and greatly was influenced by it. This impact is quite conspicuous, notably, in his most comprehensive book of poetry, West- Eastern Divan (1819). The present paper tries, through the prism of Comparative Literature especially influence studies, to investigate historical and personal evidences. At the beginning Goethe’s familiarity with the Quran and its translations which he read are elaborated on. Later on, the twelve books of West- Eastern Divan and its long epilogue, Notes and Papers Written for a Better Understanding of Divan, are analyzed very precisely, and Goethe’s sources of inspiration are, one by one, identified and explained.

با توجه به پیشرفت دنیای تصاویر دیجیتال و افزایش تعداد آنها، ارایه سیستمی جهت بازیابی تصویر، از اهمیت زیادی برخوردار است. یک سیستم بازیابی تصویر مبتنی بر محتوا باید بر اساس محتوای تصویر جستجو شده توسط کاربر، تصاویر مشابه را بیابد. لذا در این مقاله یک روش جدید به منظور بازیابی تصویر مبتنی بر محتوا ارایه شده است. برای این منظور، با توجه به اهمیت بافت اشیاء در یک تصویر، ویژگی جدیدی تحت عنوان هیستوگرام اختلاف بافت در جهت لبه برابر معرفی شده است. در روش پیشنهادی، ابتدا ویژگی هایی شامل ویژگی جدید معرفی شده، از تصاویر آموزشی استخراج شده و سپس تعدادی از این ویژگی ها انتخاب می شوند. در ادامه، با استفاده از این ویژگی ها و کلاس هر تصویر و همچنین روش یادگیری ماشین بردار پشتیبان، تصاویر در کلاس های مختلف به سیستم آموزش داده می شوند. ارزیابی روش پیشنهادی با استفاده از پایگاه داده استاندارد Wang انجام شده است و نتایج به دست آمده، توانایی روش پیشنهادی را در بازیابی تصاویر مبتنی بر محتوا نسبت به روش های مشابه نشان می دهد.کلید واژگان: بازیابی تصویر مبتنی بر محتوا، بافت، جهت لبه، هیستوگرام اختلاف بافت، ماشین بردار پشتیبانContent-based image retrieval using support vector machine and texture difference histogram featuresDue to the progress of the digital image world and increasing numbers, preparing a system for image retrieval is essential. A content-based image retrieval system should find similar images to the image search by a user. In this paper, a novel content-based image retrieval system is proposed. Considering the importance of texture in an image, we introduce a new feature as the histogram of the texture difference in the equal edge orientation. Then, the expressed features are extracted from training images in the proposed system. Then these features are learned using a support vector machine. The proposed system is examined using the standard WANG database. The results show the efficiency of the proposed system in retrieving images compared to similar methods.Keywords: Content-based image retrieval, Texture, Edge orientation, Texture difference histogram, Support Vector Machine

Background
Restless legs syndrome (RLS) is a common sensorimotor sleep disorder, and rheumatoid arthritis (RA) is an inflammatory autoimmune disease that causes disability. Previous studies showed that the prevalence of RLS varies in different populations of RA (13.2 – 68.4%). It raises the need for a pooled meta-analysis to determine a more reliable estimate. Therefore, we aimed to perform a meta-analysis to assess the pooled prevalence of RLS in RA patients.
MethodsMeta-analysis was performed according to the PRISMA checklist. Embase, MEDLINE, Ovid, Web-of-Science, and Scopus databases were used for the systematic search, and eligible studies were analyzed using R version 4.0.3. For further review, we performed sensitivity analyzes to identify influential studies.
ResultsOf a total of 763 studies, 11 studies (3 were from Europe, 4 from North America, and 4 from Asia) were suitable for synthesis. A total of 931 RA patients were identified, 300 of whom had symptoms of RLS. The pooled prevalence of RLS among people with RA from 11 studies was 34% (95% CI: 26-43%). The pooled prevalence of RLS in Europe, Asia, and North America was 48% (95% CI: 32-65%), 32% (95% CI: 18-45%), and 28% (95% CI: 15-42%), respectively. RLS prevalence was dramatically high in RA women patients (32% CI: 23-41%) than RA men patients (3%; 95% CI: 2-5%).
ConclusionThis systematic review and meta-analysis indicates that the risk of RLS in RA patients was 34% and female patients with RA were more prone to having RLS than male patients.

In this study, for the first time, thermoplastic polyurethane granule (TPU) is used as a reinforcing phase and self-healing agent in a polymer composite epoxy resin (ER) to exhibit mechanical properties recovery. When the polymer composite is damaged or cracked, TPU granules are released at the site of damage and cause auto-repair of surfaces. Therefore, TPU granules with different composition percentages were mixed in silicon molds containing epoxy resin polymer composite. 4 samples with different TPU granules percentages were selected (A= 0 Wt.% TPU, B=10 Wt.% TPU, C=20 Wt.% TPU, and D=30Wt.% TPU). At first, making a deep cut in 4 polymer composite samples, the self-healing process and mechanical properties improvement are investigated by mechanical tests. In the self-repairing behavior of self-healing samples, it is observed that polymer composite samples with self-repairing agents of ER+20 Wt.% TPU granules had the highest self-healing efficiency (60.2%) compared to other specimens. A mechanical test shows that Sample C has a higher Young’s modulus (4.837 MPa) and higher tensile strength (9.46 MPa). Also, the impact test illustrated Sample C has a higher impact energy of 7.1 (J/m). Therefore, sample C has the highest mechanical properties among self-healing samples.Keywords: Self-healing, polyurethane, Resin epoxy, Mechanical Properties

Background
In 2017, the American Academy of Pediatrics (AAP) updated clinical practice guidelines for the diagnosis and management of hypertension in children. The present study aimed to assess the prevalence of hypertension in Iranian children based on the latest guidelines.
MethodsData on 7301 student participants (3589 boys and 3712 girls) aged between 7-12 yr were assessed. The data were extracted from the fifth Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease (CASPIAN V) school-based study conducted in the 30 provinces of Iran in 2015. Blood pressure (BP) was classified as normal, elevated BP, and stage 1 and 2 hypertension using weighted analysis and the 2017 AAP guidelines. All analyses were performed in STATA 14.0 statistical software, with findings presented in terms of prevalence.
ResultsThe overall prevalence of high BP in Iranian children was 14.7%. In addition, 15.1% of boys had high BP, with 9.4% and 1.7% of them with stage 1 and 2 hypertension, respectively. Moreover, 14.3% of girls had high BP, of which 10% had stage 1 and 1.3% with stage 2 hypertension. For elevated hypertension, it was observed in 4% of boys and 3% of girls.
ConclusionUsing the 2017 AAP guidelines demonstrated a higher prevalence of hypertension in children (14.7%) in Iran. The prevalence of hypertension in boys was slightly higher compared to girls.

Introduction
The present systematic review and meta-analysis aims to conduct a comprehensive and complete search of electronic resources to investigate the role of administrating Chondroitinase ABC (ChABC) in improving complications following Spinal Cord Injuries (SCI).
MethodsMEDLINE, Embase, Scopus, and Web of Sciences databases were searched until the end of 2019. Two independent reviewers assessed the studies conducted on rats and mice and summarized the data. Using the STATA 14.0 software, the findings were reported as pooled standardized mean differences (SMD) with 95% confidence intervals (CI).
ResultsA total of 34 preclinical studies were included. ChABC administration improves locomotion recovery after SCI (SMD=0.90; 95% CI: 0.61 to 1.20; P<0.001). The subgroup analysis showed that the differences in the SCI model (P=0.732), the severity of the injury (P=0.821), the number of ChABC administrations (P=0.092), the blinding status (P=0.294), the use of different locomotor score (P=0.567), and the follow-up duration (P=0.750) have no effect on the efficacy of ChABC treatment.
ConclusionThe findings of the present study showed that prescribing ChABC has a moderate effect in improving locomotion after SCI in mice and rats. However, this moderate effect introduces ChABC as adjuvant therapy and not as primary therapy.

The chapters are entitled as follows: The Persian Epic, Ferdowsi, the Poet, The Book of the Kings, Epics and Empires, and Empires Fall and Nations Rise. The book is a study in the field of "World Literature". It is strongly contextualized in post-colonial debates. The author has two major goals in mind: a) to introduce The Shahnameh, to the Western readers, notably students (those who know English) and b) to challenge the concept of “World Literature” in the Western academia. To Dabashi, in our re-conceptualizing the Shahnameh as world literature, first and foremost, the Eurocentric world needs to be reassessed. The “World” in “World Literature,” as we use the term today, is an imaginary (“Western”) world— an imperial, colonial world. The Present book is the product of the author’s many years of teaching at Colombia University. The first chapter is about the genealogy of the Shahnameh, the introduction of the genre of epic writing and its pre-Islamic origin. In chapter two, the biography of Ferdowsi and the historical context of the Shahnameh are described. Chapter three deals with three main components of the Shahnameh (the mythical, heroic, and historical) and its famous and powerful stories. Next chapter traces the history of the Shahnameh in different periods. Finally, the last chapter discusses the later history of the Shahnameh and its political uses and abuses.Keywords: World Literature, the Shahnameh, epic, Dabashi
