Abstract

Background: Accumulation of triglycerides in the liver i.e. steatosis, is a well-known side-effect of tamoxifen administration to patients suffering from breast cancer. Cichoriumintybus (chicory) is a plant used as traditional medicine for curing liver disorders. In this study, the effects of extract prepared from chicory roots on tamoxifen-induced liver steatosis and related biochemical factors in animal model using rats has been investigated. Methods: Female rats of Wistar strain were divided into four groups and treated as follows; 1-Control: received vehicle; 2- Chicory root-extract treated: rats were given by gavage the aqueous chicory root extract (1 g/kg body weight/day for 14 days).3- Tamoxifen-treated: rats received tamoxifen (1 mg/kg body weight/day, for 7 days). 4- Tamoxifen+chicory-group: animals received tamoxifen (1 mg/kg body weight/day for 7 days) followed by chicory extract given by gavage (1 g/kg body weight/day for 14 days). After treatment, blood was collected by cardiac puncher, plasma was separated and plasma levels of glucose, total protein, triglyceride, cholesterol,LDL-C, HDL-C and activities of ALT, AST and ALP were measured. Liver tissues were homogenized used for measuring tissue triglyceride and histological examinations. Results: The data show that tamoxifen treatment caused a significant decrease in the level of serum cholesterol, HDL-C and total protein. However, serum ALT level was increased in tamoxifen-treated rats compared to controls. Increased serum ALT in tamoxifen-treated rats was recovered in rats treated with plant extract (tamoxifen+chicory-group). HDL-C and total protein levels were unaffected in rats fed chicory extracts. Tamaxifen-treated animals showed signs of liver steatosis as shown by histological examination and accumulation liver triglyceride. The steatosis markers such as accumulated triglyceride in liver was significantly reduced due to the plant extract treatments when compared to tamoxifen-group. Conclusions: Dietary extract prepared from chicory roots is effective in modulation of  tamoxifen-induced liver damage and steatosis.

Abstract

Based on the interaction between science and religion, Nancy Murphy turns to a special version of non-transitive physicalism that uses empirical science, physicalism, and the Bible to formulate her holistic physicalism; A middle position between essential dualism and illusionism that defines humans as spiritual beings and hides the problem of the mind within it. Murphy brings the soul into holistic physicalism with his theological assumptions and not with scientific evidence and philosophical arguments. The distinguishing feature of non-transmission physicalism from transmission physicalism is the attention to the explanatory gap in the issue of "supervenience". Holistic physicalism has not filled this gap and has only changed the form of the problem from explaining the relationship between human parts to explaining the relationship between human dimensions. Therefore, combining the universal and weak perceptions of supervenience, along with the positive and negative teachings of holistic physicalism, that is, the use of pure holistic physicalism and avoiding introducing theological presuppositions in a philosophical theory, can be used to solve the problem.

Abstract

Background: Human papillomavirus (HPV) is one of the most common causes of sexually transmitted disease (STD) in humans. HPV is associated with gynecologic malignancy and cervical cancer among women worldwide. In the current study we sought to determine the prevalence rate of HPV in Iranian women identified with cervical infections.
Materials and Methods:  Prevalence rate of HPV in Iran was investigated from 2000-2016 using several databases including Medline, Web of Science, Embase, Google Scholar, Iranmedex, and Scientific Information Database. Statistical analysis was performed by Comprehensive Meta-Analysis (V2.2, Biostat) software. Random effects models were used by taking into account the possibility of the heterogeneity between the studies, which was tested through the Cochran’s Q-statistic.
Results: The meta-analyses showed that the prevalence rate of HPV infections was 38.6 % (95% CI, 27.9-50.5) among Iranian women with cervical infections. The further stratified analyses indicated that the prevalence rate of HPV was higher in the studies conducted during the 2000-2008 years.
Conclusion: The results of the present study underscore the need for further enforcement of STD control strategies in Iran. Establishing advanced diagnostic facilities for HPV, vaccination of high risk groups, and continuous monitoring of HPV are recommended for HPV prevention and control.

Abstract

An example of Rorty's confrontation with the analytical philosophy is his opposition to Davidson's attempt to propose a semantic theory based on truth. According to an anti-metaphysical approach to Truth, Rorty believes that the use of the phrase "p is true" is simply to confirm a claim that we consider ourselves or others justified in making. Although Davidson is against the metaphysical approach to truth, based on a Tarskian truth definition, he believes that a notion of truth more robust than Rorty will admit is required to propose a theory about meaning. Rorty's Wittgensteinian response to Davidson is that not only the conversation between the speaker and the interpreter is not conditional on knowing a theory of meaning based on truth, but the attempt to say something more than what we can say about truth leads us to the confusions of the metaphysical tradition. This article, referring to Davidson's writings, shows that Davidson's effort to propose a semantic theory based on truth inevitably leads him to express metaphysical interpretations.

Abstract

The eggs and larvae of the Indian meal moth, Plodia interpunctella (Hübner), are widely used in mass rearing of parasitoids and predators. Feeding indices and some biological parameters of P. interpunctella were studied on bran of different wheat cultivars ('Back-cross Roshan', 'Khooshe Pishgam', 'Khoshki line 9', 'Arg', 'Alvand', 'Pishtaz', 'WS-89-2', 'Sepahan' and 'Bam') when incorporated into artificial diets under laboratory conditions (25 ± 1 ºC, 65 ± 5% R.H., and a 16:8 h light-dark photoperiod). The efficiency of conversion of ingested food was highest on 'Back-cross Roshan' (98.79 ± 8.48%) and lowest on 'Pishtaz' (64.56 ± 9.66%). The highest and lowest percentage of mortality of P. interpunctella larvae were on 'Pishtaz' (56%) and 'Back cross Roshan' (12%). Our results showed that larval growth index was highest on 'Khoshki line 9' (5.81) and lowest on 'Pishtaz' (3.33). Moreover, the highest daily and total fecundity were detected in moths that were reared on 'Back-cross Roshan' (37.6 ± 0.93 and 177.3 ± 1.61 eggs, respectively). The results demonstrated that, among different wheat cultivars tested, 'Back-cross Roshan' was the most suitable cultivar for P. interpunctella rearing in order to optimize the mass production of natural enemies.

Abstract

The issue of management and planning for urban fringe in different countries always experience different approaches, attitudes that are generally in the form of protection or development of urban fringe and surroundings areas, because it depends on political, economic and institutional developments over time. For this reason, there is no uniform and formal definition of urban fringe among different countries. Over the past five decades, city of Tehran has adopted different policies in the plans and provided projects which were different in the preparation and implementation. In the present study, five decades of planning for the Urban Fringe of Tehran are investigated and analyzed, and these programs have been studied and analyzed from two dimensions of policy and quality. The paper is applied and is based on a non-intrusive interpretive approach. The information gathering tools are library studies and use of various sources and texts. The study's findings for policy analysis identified five categories (management, planning, organization, conservation, development) and for analyzing the quality of the seven categories (program presentation, effect of reality, popular participation, infrastructure capacity, land status, implementation and adaptability). The results of the analysis of the programs show that in the developed programs the main approach and policy is based on the protection of Urban Fringe, which in order to achieve it should improve the integrity (due to the way of implementation) and legitimacy (due to lack of public participation) of the programs.

Abstract

 Through the Personal Unity of Existence (PUE), Mulla Sadra explains the relationship between the Necessary and contingent beings using concepts such as manifestations and appearances. While they align with the PUE, their linguistic vagueness may lead to multiple interpretations. This study, adopting an analytical-critical approach and drawing on metaphysical grounding, seeks to provide a framework for resolving this vagueness. Grounding, characterized by its non-causal nature and hyper intentionality, enables a redefinition of these Sadrian notions and contributes to clarifying Mulla Sadra’s terminology as well as a more precise understanding of the Necessary-contingent relationship. By integrating traditional and analytical perspectives, this research highlights the potential of metaphysical grounding in analyzing Sadra’s theory.

Abstract

Lefevere  considers translation as a kind of rewriting that is informed by the extra-systemic limitations like ideology and intra-systemic limitations like poetics. Adopting a descriptive-analytical approach, this research seeks to study the chebli’s rewriting of  the ghazal 10th and 12th of Hafez The final result of this research, shows this rewriting is influenced by Poetic limitation and ideological . Manifestations of Lefeverechr('39')s view can be seen in the form of poems and manipulating the rhythm,  music,inverting the use of pronouns, increasing some words, and domesticating,with the mystical attitude oon the rewriting of monastic symbols , and  feast (bazm). Sometimes it is far from Lefevere ‘s view by exaggerating, unclear meaning and the same reception of "Pir"  and "Sheikh".

Abstract

In the number of verses, the words "Kharasa" and "Zanna" are companion and are known as synonymous. The present study aims to explain exact meaning and distinction between the two words by semantically analyzing them and analyzing the context in that Quranic verses. The findings of the study indicate that the meaning of the word "Kharasa" is estimation and conjecture and is used in the Arabic language to estimate the number of palm dates. In the intensification form, "Kharrās" means someone who has different beliefs in his estimation that have no basis. In the meantime, Persian translators have used it to mean lying, speculating, thinking, estimating, speak in vain, dumb, incorrect explanation, forgetting divine utterances and ebey the soul imperative, exaggerated, defamatory, conjecture and irrelevant that all of them (except estimating and conjecture) have problems and this article has addressed them. Also the correct meaning of "Zanna" is "suspected", and the verses where two words come together, first speak about the "opinion" and then about the "expression of that opinion".

Abstract

Shirin and Farhad collection; the Kurdish version of Nezami’s original work by Mam Ahmad Lotfi is one of the popular examples of this genre. This work has a simple and fluid language, which narrates the history of Shirin and Farhad with a legendary structure. In the Kurdish version, with the exception of the names of the characters, the main course of events and the general framework of the story are different. The story of this poem is based on the evaluation of the myth content of the subcategory of legends in which a dragon catches a girl until rescued by her hero. Nevertheless, the comparative study of both poems from the viewpoint of the mythological manifestations indicates the infrastructure and the common theme of these works. Thus, Khosrow (in Khosrow and Shirin) and Farhad (in the Kurdish version) are considered the martyred god of fertility, with the difference that in the Kurdish version, Farhad, like the other gods of fertility, has no resurrection. In both stories, Shirin plays the role of goddess of fertility and love in different ways. The subject and function of the myth of fertility historically represent the period of agriculture and philosophically reflect the resurrection of man in the other world.

Abstract

Backgrounds: Aspergillus fumigatus is a pathogen responsible for invasive aspergillosis and the main leading cause of death in immunosuppressed individuals. The present study aimed to evaluate the impact of eugenol-loaded chitosan nanoparticles on the expression of CYP51a and CYP51b, two well-known genes responsible for triazole drug resistance in A. fumigatus.
Materials & Methods: The minimum inhibitory concentration (MIC) of eugenol-loaded chitosan nanoparticles, chitosan, eugenol, and itraconazole was determined based on the Clinical and Laboratory Standards Institute M38-E3 method at concentrations of 4.6-2400, 11.7-12000, 2-2048, and 1-256 μg/mL, respectively. The expression of CYP51A and CYP51B was evaluated in A. fumigatus exposed to 0.5, 1, and 2× of MIC concentration of NPs and itraconazole using the real-time polymerase chain reaction.
Findings: The obtained results showed that eugenol-loaded chitosan nanoparticles sucessfully reduced A. fumigatus fungal growth at 300 μg/mL concentration. MIC of chitosan, eugenol, and itraconazole was measured to be 6000, 256, and 4 μg/mL, respectively. The results of real-time PCR also revealed that eugenol-loaded chitosan nanoparticles increased the expression of both CYP51A and CYP51B in a dose-dependent manner. The expression of fungal CYP51A and CYP51B at mRNA level was significantly increased 1.26, 1.93, and 3.1-fold as well as 1.2, 2.1, and 2.4-fold at concentrations of 150, 300, and 600 μg/mL, respectively (p<.05). However, it seems that the prepared nanoparticles had a lower impact on the expression of these genes compared to itraconazole.
Conclusion: Overall, these findings suggest that the treatment of A. fumigatus with eugenol-chitosan nanoparticles could increase the expression of the CYP51 gene, suggesting the anti-fungal property of these nanoparticles.

Abstract

One of the most important and process-based schemas in the field of discourse is the "tensive process". According to this schema, a correlation occurs between the elements of semiotic sign, where meanings fluctuates from their less to the most highlighted forms. "The tensive structure" analyzes discourse on the basis of notions like intensity-extensity relationship in which meanings are formed and values are manifested.
The present article seeks to explain and analyze the Story of the Be'that (Resurrection) of Moses (AS) in Surah Taha via a Semiotic Analysis of the Tensive Model, since this Surah is faced with a live discourse with a wide range of intensive-extensive correlation. In this paper, the authors use a semiotic analysis method, relying on the tensive model to answer these questions: How are new meanings created and valued in the interactive enunciation environment of God and Moses? 2. Based on what tensive model, the discourse process of the Be'that (Resurrection) of Moses (AS) is structured? 3. How does this discursive story act based on the tensive model in the enunciation, and shape the narrative process of discourse?
The results of the present article showed that in the discourse process of the Be'that (Resurrection) of Moses (AS) in Surah Taha, God plays a key role as the enunciator. The narrative process of the Be'that (Resurrection) of Moses (AS) based on the tensive model analysis has three amplification, attenuation, and ascendant tensive model. In the discursive process of this story, the verses (9-11-12-13-17-18-19-21) sharply progress in the direction of joining the God-Moses enunciation space with the ascendant tensive model. The verses (14-15-16-22-23-24) with concurrent discontinuity-continuity form, act in the direction of concurrent amplification in the intensity-extensity correlation. Based on the tensive structure, the two verses 10 and 20 are in parallel with the descendant tensive model and in the direction of discursive discontinuity.

Abstract

ABSTRACT The effective rainfall amounts (ER) as a part of the irrigation requirement were estimated for the premature and serotinous varieties of rice in the Mazandaran Plain , using different methods. Finally the “Dependable Rain” method were selected for the estimation.Comparison of the maps, reveals that the ER amounts are more in the western part of the plain than the eastern part ; Consequently , the net irrigation requirement is low in the western part. Because knowing the minimum and maximum values of the ER with specific confidence, helps the planners in different decisions, the ER amounts were estimated at 90 , 95 and 99 percent confidence intervals. The related maps show that the confidence for ER amounts is low for both premature and serotinous varieties in the eastern part; Meanwhile the ER amounts are almost 50 milimeters more for serotinous variety than premature variety at different confidence intervals in the whole region. Also, The maps of return periods, show that the ER amounts are higher in the western and central parts than the eastern part and that the accessibility of ER, varies from lower than 80 to more than 420 milimeters in the growing season in terms of various return periods and different parts of the region.

Abstract

This research aims to provide a new product development model with an emphasis on environmental considerations and consumer participation. The model design was based on the grounded theory approach. The statistical population of this study includes all new product development experts in the food industry (including executives and academics) and thirteen experts selected by the snowball method. Results showed that the primary phenomenon involves activities and actions taken to develop a product based on environmental considerations and with the participation of consumers. The effective causes of new product development are divided into three categories: market, customer, and technical factors. The underlying conditions for product development are classified into two categories of infrastructure and capabilities. Also, penetrating interventionists were divided into three categories of cultural factors, risk management, and supportive factors. In addition, new product development includes three mechanisms: marketing, commercialization, and green design. The results of the product development model design emphasize on consequences of economic benefits and non-economic benefits.

Abstract

Aims: The role of mothers as main caregivers in toddlers with diarrhea and their familiarity with the factors associated with diarrhea is very important in managing the disease and preventing mortality. This study aimed to investigate the mothers’ performance regarding feeding a toddler with diarrhea and related factors.
Instruments & Methods: This cross-sectional descriptive study was performed on 210 mothers who had toddlers with diarrhea that were selected through convenience sampling in Tehran, Iran, in 2021. The parental socio-demographic and toddler clinical characteristics questionnaire and Mother Performance questionnaire were used to collecting data. Data analysis was done using SPSS 20 software.
Findings: The mean age of the mothers and toddlers were 32.69±6.67 years and 23.97±7.24 months, respectively, and about 51.4% of toddlers were boys. The total mean scores of mothers’ performance was 121.92±8.37. There were significant differences in the mean scores of maternal performance based on the father's education level (p=0.03) and marital status (p=0.04). Furthermore, the frequent diarrhea and referral setting (p<0.0001) were significantly different in the hygiene principles and common beliefs dimension. Mothers with wanted pregnancy have better performance in the breastfeeding dimension (p=0.04).
Conclusion: The mothers’ performance regarding diarrhea and its dietary management is low, and less than half of them have a good level of knowledge. So it is necessary to improve and implement relevant policies to control and manage diarrhea.
