A research about the real author of Marzbanname Tabari
No full textMarzbanname is the name of a book which includes narrations and allegories and marzban wrote it in old tabari language. Mohammad Ibn Ghazi maltivi in 598 A.H. and sadoddin varavini in the first half of seventh century translated it to farsi. Onsorolma' ali keykavos, the writer of Ghaboosname and Ibn Esfandyar, the writer of tarikhe – Tabarestam believe that marzban ibne Rostam ibne shervin (the 13th king of Bavandiya kiyosiye chain) in the real writer of marzbanname. But sa'daddin varavini believes that marzban ibne shervin (shervin = 5th king of Bavandiye kiyosiye) is the writer of it. Reza Gholi khane – hedayat knows marzban- Ibn – e – rostam as the outher of marzban-e-Deylami in some other books. Among the contemporaries, shefer knows marzban-ibn –e-rostam-ibn –e- sorkhab – ibn – e- Gharan as the author of marzban name, but Allame Ghazvini rejects this hierarchical order. Allame Dehkhoda, Esmaeil mahjouri, Ardeshir Barzegar and Hossein Eslami believe that marzban- ibn- e- Rostam wrote maezban name. mohammad Roshan reject all and say that there is no book named marzban name tabari.This article believes that varavini's speech about the writer of marzbanname is correct but not of onsorolma' ali keykavoos and ibne Esfandyar's speech
A Study on Cultural Capital and High-Risk Behaviors of College Students in Iran
No full textNaseri S. A Study on Cultural Capital and High-Risk Behaviors of College Students in Iran. Mediterranean Journal of Social Sciences. 2018;9(2):185-193.The term cultural capital has gained a widespread popularity as an analogy with economic capital, and capitalism rules and debates since the early 1970s. Essentially, cultural capital is not inherited, yet it is achieved through personal endeavors. Acquisition of cultural capital demands an incessant and hard work in addition to lifelong learning and acculturation. Hence, the present study examines the relationship between forms of cultural capital and high-risk behaviors of Iranian college students. The impact of each form on the incidence of high-risk behaviors is measured. A survey consisting demographical items, and items assessing cultural capital and tendency towards high-risk behaviors are applied. The results suggest a meaningfully negative relationship between sub-types of cultural capital and high-risk behaviors among undergraduate students in Iran. So, the author concluded that with an increase in cultural capital and the sub-types, the incidence of high-risk behaviors decreases consequently
P–N Junction Passivation in Kesterite Solar Cells by Use of Solution-Processed TiO2 Layer
No full textIn this work, we used a solution-processed TiO2 layer between Cu2ZnSnSe4 and CdS buffer layer to reduce the recombination at the p-n junction. Introducing the TiO2 layer showed a positive impact on VOC but fill factor and efficiency decreased. Using a KCN treatment, we could create openings in the TiO2 layer, as confirmed by transmission electron microscopy measurements. Formation of these openings in the TiO2 layer led to the improvement of the short-circuit current, fill factor, and the efficiency of the modified solar cells.This work was supported in part by the European Union's Horizon 2020 research and innovation program under Grant 640868, in part by the Flemish government, Department Economy, Science and Innovation, in part by the FEDER funds through the COMPETE 2020 Programme, and in part by the National Funds through FCT - Portuguese Foundation for Science and Technology under the project UID/CTM/50025/2013.

The role of AGAP2-AS1, DLEU2, HMBOX1_1, and UGDH-AS1 in the progression of esophageal squamous cell carcinoma
No full textAbstract Background Long noncoding RNAs (lncRNAs) have been recognized as viable prognostic and therapeutic indicators for numerous human malignancies. Nonetheless, the operational roles and fundamental mechanisms of important lncRNAs that impact esophageal squamous cell carcinoma (ESCC) remain predominantly obscure. Recently, lncRNAs have been identified to exert regulatory influence on epithelial-mesenchymal transition (EMT) via intricate interplay with EMT-associated transcription factors (TFs) and signaling pathways. The current experimental study aimed to elucidate the expression of four lncRNAs in ESCC patients and explain their potential involvement in the EMT process and the pathogenesis of ESCC. Methods In the study, the expression levels of lncRNAs (AGAP2-AS1, DLEU2, HMBOX1_1 (AC108449.2), and UGDH-AS1) and mRNAs (TWIST1, MMP13, and CD44S) between fifty ESCC and adjacent normal tissue samples were measured using quantitative real-time PCR. Results The upregulation of CD44S (36%), TWIST1 (52%), DLEU2 (58%), AGAP2-AS1 (62%), and MMP13 (74%), were indicated in ESCC samples, while the downregulation of UGDH-AS1 and HMBOX1_1 were found in 62% and 64% of patients, respectively. The expression levels of lncRNAs and EMT-related markers were found to be significantly correlated in several patient clinicopathological traits (P < 0.05), representing correlations between AGAP2-AS1, DLEU2, HMBOX1_1 (AC108449.2), and UGDH-AS1 with EMT status in ESCC. Conclusion Our results have unveiled that these lncRNAs, which regulate EMT, may play a crucial role in the regulatory process of EMT via the CD44S-TWIST1-MMP13 axis. Moreover, it may be assumed that lncRNAs present a promising avenue for both diagnosis and therapeutic intervention in the context of ESCC
The effect of induced polyploidy on phytochemistry, cellular organelles and the expression of genes involved in thymol and carvacrol biosynthetic pathway in thyme (Thymus vulgaris)
No full textInduced polyploidy usually results in larger vegetative and reproductive plant organs. In order to study the effect of chromosome doubling on Thymus vulgaris, three levels of colchicine concentration including 0.1, 0.3 and 0.5% (w/v) were applied for 6, 12 and 24 hours on apical meristem of 2- and 4-leaf seedlings. Ploidy level was evaluated by flow cytometry and microscopic chromosome counting. Chemical composition of essential oils extracted by hydro-distillation was analyzed by gas Chromatography/mass spectrometry (GC/MS) and gas Chromatography (GC). The application of 0.3% colchicine at 4-leaf seedling for 6 hours resulted in the highest survival rate and the highest number of tetraploid plants. Cytogenetic and flow cytometry analyses confirmed the increase of chromosome number from 2n=2x=30 in diploids to 2n=4x=60 in induced tetraploids. Tetraploid plants had larger leaves, taller and thicker stems, dense branching, longer trichome, larger stomata, larger guard cells, and decreased number of stomata. The number of chloroplasts and mitochondria increased significantly in tetraploid plants by 1.66 and 1.63 times, respectively. The expression of CYP71D178, CYP71D180 and CYP71D181 increased in tetraploids by 3.27, 7.39 and 2.15 times, respectively, probably resulting in higher essential oil compounds, as tetraploids outyielded the diploid plants by 64.7% in essential oil, 40.9% in thymol and 18.6% in carvacrol content
Evolving aspects of oral care in modern nursing: a systematic review
No full textIntroduction: Oral care is a critical yet often neglected aspect of nursing, essential for preventing complications like ventilator-associated pneumonia and systemic inflammation. Despite its importance, nurses face challenges due to limited training, time constraints, and inconsistent protocols. The evolving role of nurses in oral care reflects broader healthcare shifts toward interprofessional and patient-centered models. This systematic review examines these dynamics to inform evidence-based improvements. Methods: Following PRISMA guidelines, this systematic review synthesized qualitative, quantitative, and mixed-methods studies from 2015 to 2025, sourced from PubMed, CINAHL, Scopus, Web of Science, Embase, and grey literature. Search terms targeted nurses’ roles, perceptions, barriers, and interventions in oral care. Eligible studies involved registered nurses or students in healthcare settings, with data extracted on study characteristics, outcomes, and interventions. Quality was assessed using JBI and MMAT tools, and a narrative synthesis integrated findings via thematic analysis using NVivo. Results: From 2,347 records, 32 studies across 12 countries were included, covering ICUs (n = 12), general wards (n = 8), and nursing homes (n = 5), with sample sizes ranging from 7 to 1,576 participants. Key themes emerged: inadequate knowledge due to limited education, variable attitudes influenced by setting, inconsistent practices lacking standardized tools, and barriers like workload and resource shortages. Enablers included enhanced training, with over 80% of nurses in multiple studies seeking further education, patient empowerment, interdisciplinary collaboration, and policy support. Training programs, such as virtual reality simulations, improved knowledge and confidence, while resource availability enhanced practice quality. Conclusion: Nurses’ effectiveness in oral care is hindered by educational gaps, systemic barriers, and inconsistent prioritization, but bolstered by targeted training and resources. These findings can guide nursing curricula and hospital policy reforms to prioritize oral care globally. Comprehensive nursing curricula, evidence-based protocols, and interdisciplinary collaboration are essential to elevate oral care as a core responsibility. Future research should focus on scalable interventions in diverse settings to enhance patient outcomes
Modelling walking and cycling accessibility and mobility: The effect of network configuration and occupancy on spatial dynamics of active mobility
No full textPurpose: The most sustainable forms of urban mobility are walking and cycling. These modes of transportation are the most environmental friendly, the most economically viable and the most socially inclusive and engaging modes of urban transportation. To measure and compare the effectiveness of alternative pedestrianization or cycling infrastructure plans, the authors need to measure the potential flows of pedestrians and cyclists. The paper aims to discuss this issue. Design/methodology/approach: The authors have developed a computational methodology to predict walking and cycling flows and local centrality of streets, given a road centerline network and occupancy or population density data attributed to building plots. Findings: The authors show the functionality of this model in a hypothetical grid network and a simulated setting in a real town. In addition, the authors show how this model can be validated using crowd-sensed data on human mobility trails. This methodology can be used in assessing sustainable urban mobility plans. Originality/value: The main contribution of this paper is the generalization and adaptation of two network centrality models and a trip-distribution model for studying walking and cycling mobility.Design InformaticsSupport Architectur
