By studying the Qur'anic narratives, what is most visible is the amazing and elimination that includes a complete part of a story, even at a time. A pity that has been used not only in the Qur'anic stories, but also throughout the Qur'an as one of the highest literary and rhetorical manifestations of the Qur'an. This is one of the mechanisms and tools of the narrative or discourse silence process in which the signs of the narrative are eliminated and with their absence refers to the modules that the reader can rely on succession and companionship. And also from the intersection between the two and the use of brain capacity, fill those holes and gaps, thus fully view and receive the story. The important point in discourse silence is the interpretative and analytical aspect of narrative, and merely, such as the elimination of the classic rhetoric of the Nesith, which appeared in the form of metaphor, metaphor, permissible, and such equipment and to express aesthetics. In this article, we will first explain the silence of discourse in modern cognitive criticism, and then explain the narration of the life of Yusuf (AS) in the Holy Quran, based on the same validity and discourse. The result shows that discourse silence in this sura has been used in three types of structural, semantic and implicit, and with the systematic structure of the Qur'anic narrative structure, these vacuums are received and completed by the reader.

  Cancer stem cells (CSC) are the tumor-associated cells existed within tumors or hematological cancers which share characteristics similar to normal stem cells. The common characteristics of a normal stem cell and a CSC are their differentiation capacity and self-renewal in tumors. The expression pattern of CSC markers differs depending on the type and location of cancers. CD molecules are probably the most common biomarkers for CSCs. CD molecules such as CD133, CD24, CD44, CD138 and similar CD molecules are well known markers for identification of CSCs. In addition, ATP-Binding Cassette (ABC) transporters such as ABCG2 and ABCB5 as well as EpCAM, ALDH1 and CXCR4 have been used to identify certain CSCs. Therefore these markers may be considered specific for better identification and diagnosis of a specific tumor. Currently studies are in progress to find new cell surface markers which can distinguish specific markers from other markers for isolation and characterization of CSCs. The future of this area of research is promising in developing novel prognostic assays and therapeutic approaches based on cellular and signaling functions of these markers.

Having the Five Year Development Plans (FYDP) of the fisheries sector (Shilat) in mind, and based on the resources documentation and content analysis of two scenarios of the “continuation of the current trend” and the “optimal situation”, this research provides the future opportunities and threats and also suggestions towards improving the situation and relevant decision making. The assessment of production indices demonstrated that in each of the plans, except the third one, not a so-logical growth rate was envisioned for the fisheries development. Of 5% predicted growth in fisheries sector within 23 years, only 4.5%, or 90.3% of the goal, has been realized, which means the policies and programs have not been completely performed. Although possessing the world ranking of 21^st in aquaculture and 32^nd in fishing, potential and capacities in Iran indicate a far higher exploitation and utilization possibilities from the present resources, which require better policies and approaches as well as a large and targeted investment by the government

World production of caviar from the farmed sturgeon has recently so increased that in addition to compensate reduction of natural resources of sturgeon, it has also increased its share in the world market for caviar and its substitutes. Although Belarus, China and Norway are currently considered as the main exporting countries of caviar and its substitutes but, Iran solely exports caviar from sturgeon species. Having a world reputation in caviar brand, as well as the decreased natural resources, Iran aims to develop sturgeon rearing as well as modern marketing along with global standards to stand its brand and reputation as well as its world market share. The present paper reviewed the caviar and caviar substitutes market with emphasis on sturgeon caviar. During 1991-2013, caviar export from Iran decreased by 21.2 % in quantity and decreased income by about 17.2 %. However, the caviar value increased from 231000 to 680000 USD per ton.

In this study an agar/gelatin bilayer film was produced from agar and gelatin monolayers using the casting method in two phases. Then, the characteristics of this bilayer film, including water vapor permeability (WVP), water solubility, water absorption, mechanical and optical properties were compared with those of monolayer films. The results showed that  WVP of the bilayer film (3.25×10^-10 g/msPa)  was significantly lower than the agar (3.90 × 10^-10 g/msPa), and gelatin (4/32×10^-10 g/msPa). Absorption of UV light by bilayer film was significantly higher than the single-layer agar and gelatin films. Although the tensile strength of the bilayer film (10.8 MPa) was higher than the single-layer gelatin (2.86 MPa), it was lower than the single layer of agar film (30.49 MPa) (P<0.05). In conclusion, some properties of agar and gelatin films can be improved by making bilayers film of both biopolymers.

Considering the importance of fish consumption in provision of nutritious food for community as well as increasing per capita consumption, factors affecting the fish consumption behavior in Sari were prioritized in the present study. For this purpose, a field research was performed using a questionnaire on 266 consumers household. Beside descriptive statistical analysis by Spss₁₉ software, inferential analysis on nonparametric statistics was done. Factors which their average score was more than 3 were identified as the main factors and using the Friedman`s test with the possibility of (<0.001) prioritizing of effective factors were determined. The results showed that quality and freshness, hygiene of Store, properties and nutritional value, trust in seller, price, species, taste, availability, the size of fish and consumption convenience were respectively among the main factors which affect consumer’s behavior in Sari. The majority of consumers (93.6 %) did not have the tendency to consume packed fish (non-canned) and instead have a great interest to use fresh fish. In conclusion, planning to increase people`s awareness in recognizing fresh fish, close monitoring of fish suppliers, decreasing of production costs and prices, easing the access by establishing standard retail markets as well as public awareness regarding the fish nutritional value can be considered as approaches for planners and activists in the field of fisheries for increasing per capita consumption and social health.

In this study, nano drug delivery system based on graphene oxide and reduced graphene oxide- polyglycerol hybrids were constructed. Functionalization of nano graphene oxide and reduced graphene oxide was accomplished through noncovalent interaction between the π conjugated system of graphene materials and the aromatic segment in the focal point of polyglycerol polymer. Polyglycerol is a hydrophilic and biocompatible polymer that its conjugation with graphene materials was increased the colloidal stability and decreased the nonspecific interaction of graphene materials. Curcumin as an anticancer hydrophobic natural drug with low systemic bioavailability was simply loaded on these nanohybrids via π-π stacking force between the π conjugated systems of graphene materials and curcumin. Result showed that loading capacity of curcumin for reduced graphene oxide hybrid (49%) is higher than graphene oxide hybrid due to restored of π conjugated system in reduced graphene oxide. Anticancer efficiency of these drug hybrids was investigated by MTT assay. Results showed that these drug carriers have sufficient biocompatibility. Also these nano drug delivery systems showed a cytotoxic effect that was comparable to that of free curcumin. The reduced graphene oxide hybrid is preferred for delivery of curcumin due to its higher loading capacity that can provide efficient dose of drug in low level of carrier

Objective: The global HIV epidemic continues to expand and exceeding previous predictions. An effective vaccine represents the best hope to curtail the HIV epidemic. DNA vaccines induce humoral and cellular responses and mimic live vaccines without their pathogenic potential. The importance of CD8+ CTL responses in controlling HIV and SIV viremia has led to production of a series of vaccine candidates that effectively induce these responses. It is now widely believed that an HIV vaccine strategy must stimulate both a strong humoral (antibody) as well as cell-mediated (CTL) immune response.The p24 and gp41 play many important roles in host-virus interaction and pathogenesis. These proteins are considered as attractive vaccine candidate in which their immunogenecity and immunomodulatory effects have been confirmed. Materials and Methods: In this study, a construct, pcDNA3.1Hygro- (p24-gp41), was evaluated as a DNA vaccine candidate in Balb/C mice for generation of effective cellular immune responses. For immunizing, we used dendrosome, a novel family of vehicles for transfection and therapy. IFN-γ cytokine production and total antibody were detected by ELISA. Lymphoprolifration assay was performed by MTT test. Results: ELISA and MTT assays confirmed that the cited p24-gp41 fusion gene is able to enhance immune responses in mice. Conclusion: The construct that was used in this research can be a good candidate for DNA vaccine against HIV-1, if the future complementary tests demonstrate the same trends of immunogenic responses shown in this study.

The purpose of this study is to evaluate the purchase amount of shrimp in the market and the relationship between consumption amount and some of demographic characteristics. The statistical population of this study is the whole country that 10 cities including Mashhad, Tehran, Tabriz, Birjand, Kermanshah, Gorgan, Yazd, Bandar Abbas, Ilam and Shiraz were randomly selected and a total 1000 questionnaires were completed by citizens proportionate to the household population of the studied cities. In order to evaluate the number of shrimp purchases per year as well as the amount of each purchase, from the output of SPSS software and to investigate the existence of a significant relationship between consumption amount and demographic characteristics, correlation tests were used. According to the results the number of times shrimp were bought by the household varied from one to twelve times a year (average 1.71±1.11). 44.2% of households of the consumption society bought shrimp once a year and 28.6% of them bought shrimp twice a year. It was further found that the amount of shrimp purchased by household varies from 0.5 to 2 kg per purchase (average 0.92±0.26 kg). while 76.3% of households of the consumption society purchase one kilogram of shrimp in per purchase. According to the findings, consumption amount had no significant relationship with the age, job and field of study variables (p>0.05). But the relationship between this index with the education level and number of household members variables was significant (p<0.05).

Waxy-leaved mustard Boreava orientalis Jaub. and Spach. has recently become farmland invasive weed in the Kurdistan province, Iran. Hence this study was conducted better to understand the seed germination ecology of B. orientalis. Therefore, in this study, the effect of temperature and osmotic potential, salinity, and burial depth on seed germination and seedling emergence of B. orientalis was investigated in the Weed Research Laboratory of the University of Kurdistan in 2020. Seed germination of B. orientalis was determined at 10, 20, 30, and 35 °C. Boreava orientalis seeds were germinated in an aqueous solution with the osmotic potential of 0, 3, 6, 9, and 12 MPa. The levels of salt stress consisted of control 0, 50, 100, 150, and 200 mM. The burial depths were 0, 3, 6, 9, and 12 cm. The results revealed that germination started at 5 ºC with 0 osmotic potential, and no germination occurred at 30 and 35 °C with different osmotic potentials. The Lowest germination was at 30 and 35 °C; the highest was at 0 Mm NaCl concentration, and the lowest was at 200 Mm of NaCl. The highest germination was at 0 depth, and the lowest was at 12 cm. These results indicate that the germination of this weed species is sensitive and thus greatly reduced under drought and high-temperature conditions. It was also sensitive to both salinity stress and deep burial.

Waxy-leaved mustard (Boreava orientalis Jaub. and Spach.) is an invasive species recently reported in Kurdistan province in western Iran with allelopathic properties. To evaluate the effect of the extract of different parts of waxy-leaved mustard on wheat germination, an experiment was conducted as a factorial based on a completely randomized design in the Faculty of Agriculture, University of Kurdistan, Iran. The allelopathic potential of waxy-leaved mustard's root, leaf, stem, and flower were evaluated, and secondary metabolite compounds were identified. Effect of Alcohol extracts at concentrations of 0, 1, 2, 3, and 4% of roots, leaves, stems, and flowers of waxy-leaved mustard were evaluated on wheat germination Indicators. Increasing extract concentration significantly increased the inhibition of seed germination and caused a decrease in germination rate, reduction of stem length, and reduction of seed vigor index. Alcoholic extracts of waxy-leaved mustard flowers had significantly more effect compared to the alcoholic extracts of roots, even at the lowest concentration (1%). The results of this study show that waxy-leaved mustard has a strong allelopathic potential, which emphasizes the importance of reducing its allelopathic effects and developing effective management strategies for mitigating invasion risk and thereby protecting crops like wheat.

Aims: The purpose of this research was to evaluate the consumer’s behavior of farmed carp in the north of Iran (Golestan, Mazandaran and Gilan province). Method: After defining the assumptions and designing the analytical-conceptual model based on the theory of planned behavior, a suitable questionnaire was developed and completed by the statistical community. In order to evaluate the intensity of the relationship between the research variables and the model elements, as well as to check the acceptance or non-acceptance of the assumptions, the structural equation modeling method (SEM) was used. Findings: Per capita fish consumption of farmed carp consumers is 5.3 kg. Of this amount, 400 grams are canned, 600 grams are consumed in restaurants and outside the home, and 2.5 kg are consumed at home. Per capita consumption of their farmed carp is 1.4 kg, so half of their consumption is from other fish.In this research, all hypotheses were confirmed, In this way, the effect of perceived usefulness, perceived risk and quality on attitude, the effect of normative beliefs, moral obligation and household income on subjective norms, the effect of control power, control belief, experimental records, advertising and education on the perceived behavior control, the effect of attitude, subjective norms and perceived behavior control on the decision to buy farmed carp and the effect of the decision to buy and perceived behavior control on the final behavior were reported to be significant (p<0.05). The values of the effect coefficients showed that the most effective variable on the attitude, subjective norms and perceived behavior control, is quality (with an effect coefficient of 0.46), income (with an effect coefficient of 0.44) and experience records (with an effect coefficient of 0.37), respectively. Also, among the three main elements of the model, the attitude had the greatest effect on the decision to buy and consume farmed carp (with an effect coefficient of 0.48).

The combined effects of salt percentage (0.5 or 1%), its adding order (before or after the fermentation) and different ratios of NaCl/KCl (100/0 and 50/50) were used in the probiotic Doogh. Two probiotic bacteria (Lactobacillus acidophilus LA-5 and Bifidobacterium lactis BB-12), along with the yogurt bacteria were used. pH, acidification and redox potential were measured during the fermentation period. Moreover, viability of probiotic bacteria was determined within 7-day intervals during the storage period. The sensory parameters were also evaluated at days 0 and 21. The partial substitution of NaCl with KCl in the studied concentration had a positive influence on the viability of probiotics. Treatments containing 1% NaCl/KCl and 0.5% NaCl/KCl which were added before fermentation showed the maximum viability of probiotics. The treatments with 0.5% NaCl and then 0.5% NaCl/KCl before fermentation showed higher acceptance. Thus the substitution of 0.5% NaCl with KCl was acceptable. In whole, the treatment containing 0.5% NaCl/KCl before fermentation was the best one for probiotic Doogh with substituted salt.
