Exploring EFL Learners’ Autonomy in Reading Comprehension: Computer-Assisted versus Conventional Contexts

This study explored the autonomy of advanced English as a Foreign Language (EFL) learners in reading comprehension through scaffolding and jigsaw in computer-assisted and conventional contexts. After being homogenized through the reading section of DIALANG proficiency test, a total of 80 female advanced EFL learners with the age range of 21 to 45 were selected as the participants of the study. They were randomly assigned to four groups: experimental group A (scaffolding in a conventional context), experimental group B (scaffolding in a computer-assisted context), experimental group C (jigsaw in a conventional context), and experimental group D (jigsaw in a computer-assisted context). Next, the autonomy in RC questionnaire, which was designed and piloted by Ebadi and Shirzad (in press), was administered as the pretest. Then, the learners in each group took part in three months (16 sessions) autonomy in reading comprehension training courses. After the treatment, the same autonomy in RC questionnaire was administered as the posttest. One-way ANCOVA was used to analyze the quantitative data. The results revealed that although both jigsaw and scaffolding approaches were successful in both conventional and computer assisted contexts from pre-test to post-test, the scaffolding method proved more effective. Moreover, both the scaffolding and jigsaw approaches were more effective in computer-assisted environment compared to conventional contexts, with the scaffolding CA approach outperforming the jigsaw CA technique. The findings’ implications for learners, teachers, and syllabus designers are discussed in both contexts

Comparing the expression levels of mRNA for MMP-7 in gastric mucosa of patients with H. pylori infection and uninfected patients

Background and purpose: The expression of growth factors, proteolytic enzymes, fibrogenic factors, and cytokines are altered in Helicobacter pylori (H. pylori) infected gastric mucosa. Matrix metalloproteinases (MMP) are a family of zinc-dependent homologous enzymes digesting most of the components of the extracellular matrix and basement membrane and are involved in remodeling and functioning of the biological processes. The purpose of this study was to compare gene expression of matrix metalloproteinase-7 (MMP-7) in patients with H. pylori-infected and uninfected individuals with gastrointestinal diseases. Materials and methods: This study was conducted in 50 H. pylori-negative patients and 50 H. pylori-positive patients being admitted to Shahrekord Hajar Hospital due to gastrointestinal diseases in 2014. The participants’ demographic information was collected and sampling was done. First DNA was extracted, and then PCR was performed to check for the presence of 16sRNA and UreC. The RNA from each sample was also extracted and cDNA was prepared. Afterwards, the expression of MMP-7 was measured by real time-PCR using specific primers and probes. Results: MMP-7 mRNA expression was significantly higher in biopsies of H. pylori-infected patients compared to that in H. pylori-uninfected patients (P<0.0001). Conclusion: Increased expression of MMP-7 can be effective in inflammatory response and development of the disease. It could be used as a key marker for early diagnosis of gastrointestinal diseases and gastric cancer. © 2016, Mazandaran University of Medical Sciences. Engineering. All rights reserved

Treatment of hyperfunctioning thyroid nodules by percutaneous ethanol injection

BACKGROUND: Autonomous thyroid nodules can be treated by a variety of methods. We assessed the efficacy of percutaneous ethanol injection in treating autonomous thyroid nodules. METHODS: 35 patients diagnosed by technetium-99 scanning with hyperfunctioning nodules and suppressed sensitive TSH (sTSH) were given sterile ethanol injections under ultrasound guidance. 29 patients had clinical and biochemical hyperthyroidism. The other 6 had sub-clinical hyperthyroidism with suppressed sTSH levels (<0.24 μIU/ml) and normal thyroid hormone levels. Ethanol injections were performed once every 1–4 weeks. Ethanol injections were stopped when serum T(3), T(4 )and sTSH levels had returned to normal, or else injections could no longer be performed because significant side effects. Patients were followed up at 3, 6 and, in 15 patients, 24 months after the last injection. RESULTS: Average pre-treatment nodule volume [18.2 ± 12.7 ml] decreased to 5.7 ± 4.6 ml at 6 months follow-up [P < 0.001]. All patients had normal thyroid hormone levels at 3 and 6 months follow-up [P < 0.001 relative to baseline]. sTSH levels increased from 0.09 ± 0.02 μIU/ml to 0.65 ± 0.8 μIU/ml at the end of therapy [P < 0.05]. Only 3 patients had persistent sTSH suppression at 6 months post-therapy. T(4 )and sTSH did not change significantly between 6 months and 2 years [P > 0.05]. Ethanol injections were well tolerated by the patients, with only 2 cases of transient dysphonia. CONCLUSION: Our findings indicate that ethanol injection is an alternative to surgery or radioactive iodine in the treatment of autonomous thyroid nodules

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

The comparison of self-disclosure, intimacy and emotional processing in female with and without social phobia

The objective of this study is the comparison of self-disclosure, intimacy and emotional processing in female with and without social phobia. The method of study was causal-comparison. The population was all women married in Ardebil city that referred to Ardebil’s counseling center and had received a diagnosis of social phobia. From among these girls, 40 were selected by accessible sampling. 40 normal subjects were among married women who work in Ardebil Azad University. Female with and without social phobia matched in education, age and duration of marred. Both groups completed the social phobia Scale, self-disclosure Scale, intimacy Scale and emotional processing Scale Data analyzed using multivariate analysis of variance (MANOVA). The results showed self-disclosure and intimacy in female with social phobia lower than female without social phobia. Also female with social phobia compared to normal female had higher emotional processing. This research can be useful in prevent, treatment and counseling services to women with social phobi

Prevalence of cagA and babA2 genes in Helicobacter Pylori strains Isolated from Iranian gastrointestinal disorder patients and their gas-tritis classification

Helicobacter pylori is a spiral gram negative flagellate bacteria and localize in the stomach. H.p infection is a worldwide health problem and identified as an important cause of gastritis and gastric cancer and its ability to develop such disorders is related to its virulence factors and environment. cagA is the most important Hp virulence factor that directly penetrate into gastric epithelial cells by bacterial secretion system (T4SS) from pathogenicity island (PAI) and disrupts cell homeostasis. Adherence factors are significant for bacterial colonization and suitable function of other virulence factor. Blood group antigen binding adhesion (babA) is an outer membrane protein (OMP) that binds to ABO blood group antigen and can stimulate inflammatory response in gastric cells. Our main target was to determine the roles and prevalence of cagA and babA2 virulence factor in gastrointestinal disorders in Iranian patients. Existences of These factors were determined by PCR in 218 patients with gastrointestinal disorders. Semi-quantitative methods of scoring according to the Updated Sydney classification system were used for detection of H.pylori density, neutrophil and monocyte cells infiltration. A high prevalence of cagA positive (81.4%) and babA2 positive (35%) were found. The most combined genotype (cagA&babA2) prevalence was found in gastritis & ulcer (100%) (P < 0.001). High prevalence of cagA positive observed in active inflammation phase 76.9% and high prevalence of babA2 positive was in active phase 61.1% of H.pylori gastritis (P=0.001) . Results of this study showed information about the high prevalence of cagA genes in H.pylori infected patients and their rolls in active gastrointestinal disorder

Intensified Th9 Response is Associated with the Immunopathogenesis of Active Ulcerative Colitis

Abstract Background: Ulcerative colitis (UC) is a chronic inflammatory disorder of the large intestine histologically characterized by indistinct sustained inflammatory responses. Genetical susceptibility and environmental factors’ effects play the roles in disease occurrence and it can be life threatening if remains untreated. It seems that intensification of inflammatory responses in this condition is not restricted to a specific cell line of T lymphocytes. Our aim was to determine the number of T helper 9 (Th9) cells in inflamed colonic biopsies of UC patients. We also correlated it with interleukin (IL)-9 protein level in addition to certain genes expressions associated with Th9 phenotype. Methods: Expression of CD4 and IL-9 were evaluated by immunohistochemical staining. Enzyme linked immunosorbent assay (ELISA) was performed to determine the colonic expression of IL-9 protein and finally mRNA expressions of interferon regulatory factor 4 (Irf4), Smad2, and Smad3 were measured by real-time polymerase chain reaction (RT-PCR) as critical transcription factors of Th9 differentiation. Results: Number of Th9 cells was significantly increased in inflamed samples as compared with normal tissues. Also quantitative measurement of IL-9 by ELISA and mRNA expressions of Irf4, Smad2, and Smad3 showed notable correlative enhancements in patient’s samples. Conclusion: Function and number of Th9 cells are up-regulated in the inflamed mucosa of UC patients as with the protein secretion of IL-9 and mRNA expressions of Irf4, Smad2, and Smad3, so Th9 cells and IL-9 may become remarkable therapeutic targets for IBD treatment in the future. © 2018 Taylor & Franci
