- چکیده:
- چکیده انگلیسی: To direct m-game to be a possible didactic option for Iranian TVT (Technical Vocational Training) trainees, in this study m-game-mediated (Mobile Game-Mediated) materials delivery was incorporated into the conventional teaching method in the blended ESP reading skill platform. So, 52 male trainees fromTechnical and Vocational College of Isfahan were selected by convenience sampling. Afterwards, 48 trainees were defined as homogeneous using Englishtag Test to learn ESP in 16 triads under two different blended learning scenarios in 18 sessions in the academic year 2014-2015. While the first group of the trainees practiced in the blended learning situation with ready-made displaying device and materials, the second-group trainees practiced the same content through the medium of their own self-made PDA (Personal Digital Assistant) and materials; in this way, their learning performance assessed continuously in and outside the classroom. To employ tree-prong approach, interest survey and focus-group interview were embraced, as well. Overall, descriptive and inferential analyses of the collected data disclosed that trainees who were involved in the process of materials development were more excited and learned more than their counterparts who practiced via prefabricated devices and materials. Consequently, self-made (vs. prefabricated) m-game-mediated blended platform was found to be more liable to teaching and learning ESP reading skill.

- چکیده:
- چکیده انگلیسی: Many organizational and environmental factors affect the information disclosure and the quality of its presentation; organizational culture is the most important factor among these factors. The organizational culture that is based on transparency will provide the information environment dynamism and it will also lead to the improvement of the quality of information disclosure by the business units. This effect is more prominent especially in the countries such as Iran which has a variety of tribes and population groups with different cultures. In this regard, the aim of this study is to evaluate the impact of organizational culture on the voluntary disclosure in Iranian firms. The study of organizational culture of Iranian firms and its impact on the voluntary disclosure in 2015 has shown that the organizational culture that is based on involvement and consistency has a positive and significant impact on the voluntary disclosure of information. Also, the organizational culture based on a mission has an adverse impact on the voluntary disclosure. These results could be useful for the policies of the senior managers of Iranian firms in the field of organizational culture and they will also lead to the improvement of the implementation of accountability procedures. Also, by identifying and modifying the types of company's organizational culture, we can lead to the enhancement of the voluntary disclosure.

- چکیده:
- چکیده انگلیسی: Background/objectives: Common variable immunodeficiency (CVID) is a heterogeneous syndrome described by defective antibody production and occurrence of multiple clinical manifestations including autoimmune, lymphoproliferative, and granulomatous diseases. Genes within the major histocompatibility complex (MHC) region have previously been reported to be involved in the pathogenesis of the disease.
Methods: To elucidate the human leukocyte antigen (HLA) association, PCR was performed to clarify type HLA B, DR, and DQ alleles in a large sample of Iranian and Swedish CVID patients.
Results: No HLA association was observed between Iranian patients with “sporadic” CVID (n=50) and controls. A slight HLA association (B8, DR3, DQ2) was found in Swedish CVID patients (n=95). However, the latter was entirely due to an association in the familial form of the disease. Using 13 informative multiplex families with patients affected by CVID and IgA deficiency (IgAD), shared haplotypes such as HLA-B8-DR3-DQ2; HLA-DR1-DQ5; HLA- DR4- DQ3, and HLA-DR7-DQ2 were observed.
Conclusions: Based on our results, we hypothesize that only the familial form of CVID/IgAD may have a common HLA-associated genetic background, whereas “sporadic” cases show no HLA association.- انتشار مقاله: 28-01-1397

- چکیده:
- چکیده انگلیسی: Objective: X-ray cross-complementing group 1 (XRCC1) and 8 Oxo guanine DNA-glycosylase 1 (OGG1) genes are implicated in the repair of single-stranded breaks (SSBRs) and base excision repair (BER) pathways. Common polymorphisms in DNA repair genes are supposed to decrease the capability of DNA repair and cause genetic instability. This study was designed to investigate the association between XRCC1 (rs25487) and OGG1 (rs1052133) polymorphisms and susceptibility to colorectal cancer (CRC) in the Ahvaz city, south-west Iran. Methods: This case- control study comprised 150 patients and 150 controls that were selected from 2 educational hospitals in Ahvaz. They were matched for age and gender, and their genotyping was carried out by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: Our results indicate that the frequency of the Gln (A) allele of XRCC1 (rs25487) is significantly higher in colorectal cancer patients, compare to controls (p = 0.01, OR: 1.54, 95% CI 1.9–13.3). Significant increased risk of cancer was observed in XRCC1 (rs25487) genotypes (p = 0.001 OR: 5.3, 95% CI 1.9–14.2 for Gln / Gln), while no association was found between OGG1 (rs1052133) and colorectal cancer risk (p = 0.6). Conclusion: Our study suggests that XRCC1 (rs25487) polymorphism might be associated with an increasing risk of CRC in Ahvaz. It also demonstrates positive correlation between the XRCC1 (rs25487) genotypes and demographic characteristics, such as smoking and increased age in patients and control groups.
