The learning potential of pair/team work in language assessment has been demonstrated in the literature, albeit with little concern about challenges faced by the educators to implement it. To contribute to this line of research, the present study aimed to investigate the impact of paired peer assessment, teacher feedback, and group peer assessment on students’ writing performance. To do so, 69 second-year university students of the English language were assigned to three classes. The first class received regular teacher feedback, the second class was instructed to work in pairs and assess each other’s work, and students in the third class were divided into groups of four members and a group leader was assigned to each group by the teacher. Team leaders’ responsibility was assessing and providing feedback on their fellow members’ writing samples. The results showed a growth in the performance of students in paired peer assessment class in comparison to the other two classes. In group peer assessment class, the group heads outperformed their peers but the overall performance of the class was lower than paired peer assessment class. The findings suggest careful consideration of the circumstances under which peer assessment can be employed and call for more research on the contribution of non-pedagogical factors to assessment designs.

The present study aimed at isolating and elucidating the structure of the main components of Pistacia khinjuk L. and exploring its potential anti-inflammatory effect in different experimental models. The extract was evaluated for antiinflammatory activity by measuring paw volume in three experimental models. Then, prostaglandin E2 (PGE2) level, ear edema, tissue myeloperoxidase (MPO) activity, histopathology, nitric oxide (NO) level, and tumor necrosis factor-a (TNF-a) level were assessed. Seven phenolic compounds, mainly flavonoids and galloylated compounds, were isolated from the aqueous methanol extract: gallic acid (1), methyl gallate (2), quercetin-3-O-b-d-4C1-galactopyranoside (hyperin) (3), myricetin- 3-O-a-l-1C4-rhamnopyranoside (myricitrin) (4), 1,6-digalloyl-b-d-glucose (5), 1,4-digalloyl-b-d-glucopyranoside (6), and 2,3-di-O-galloyl-(a/b)-4C1-glucopyranose (nilocitin) (7). The anti-inflammatory activity was evidenced by decreased carrageenan-induced rat paw edema and PGE2 elevation. In the croton oil–induced ear edema model, MPO activity was significantly inhibited, and inflammatory histopathological changes were ameliorated. In the rat air pouch model, NO generation and TNF-a release were significantly inhibited. The isolation and nuclear magnetic resonance spectral data of compound 6 from the genus Pistacia are revealed for the first time. Also, P. khinjuk L. aqueous methanol extract possesses anti-inflammatory activity in several experimental models.

Background: Breast cancer is the most common cancer in women. One way to decrease the burden of this cancer is early detection through mammography. This study compared the effectiveness of two different educational methods for teachers' uptake of mammography based on the Health Belief Model. Materials and Methods: The current study was a randomised trial of 120 teachers over 40 years old in two groups receiving multimedia or group education, both based on the Health Belief Model. Participants completed questionnaires before, immediately and three months after educational intervention. Mammography was evaluated before and after educational intervention. Results: The participants in the two groups were demographically similar. Comparison showed no difference noted in the scores of knowledge, perceived barriers, susceptibility, and severity constructs between two groups (p > 0.05). Health motivation and benefit were perceived to be higher in the group education compared to the multimedia group. There was a significant difference in mammography between two groups after the intervention (p= 0.003). Conclusions: Planning and implementation of educational program based on the Health Belief Model can raise knowledge and increase participation in mammography especially with group education.

Background: Ardabil, a Northwestern province of Iran, was found to have the highest rate of gastric cancer (GC) in the country (ASRs = 51.8/100,000 for males and 24.9/100,000 for females) and one of the highest gastric cardia cancer rates in the world. The aim of the present study was to assess the associations of the cagA and babA2 status of Helicobacter pylori with GC in the Ardabil population. Materials and Methods: A total of 103 patients with non-atrophic gastritis (56) and GC (47), who underwent endoscopy at the Imam Khomeini Hospital in Ardabil, were assessed. The status of 16S rDNA, cagA and babA2 genes was determined using PCR and histopathological assessment was performed. Results: The following genotypic frequency was observed: cagA+ (50.6%), cagA-(49.4%), babA2+ (26.5%), babA2- (73.5%) cagA+/babA2+ (19.3%), cagA-/babA2+ (7.2%), cagA+/babA2-(31.3%), cagA-/babA2-(42.2%). Although the frequency of the cagA+, cagA+/babA2+ and cagA-/babA2+ genotypes in patients with GC (55.6%, 25.9%, and 14.8%, respectively) was higher than in those with NAG (48.2%, 16.1%, and 3.6%, respectively), the difference did not reach significance. In contrast, the presence of the babA2 gene (40.7% vs 19.6%) significantly increased the risk of GC; the age-sex-adjusted odds ratio (95% confidence interval) was 5.068 (1.506-17.058; P=0.009), by multiple logistic regression. Conclusions: It is proposed that the H. pylori babA2 positivity might be considered as an important determinant of GC risk in Ardabil.

Social Determinants of Health and 5-year Survival of Colorectal Cancer
Heidarnia, Mohammad Ali,Monfared, Esmat Davoudi,Akbari, Mohammad Esmail,Yavari, Parvin,Amanpour, Farzaneh,Mohseni, Maryam Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9
Background: Early in the 21st century, cancers are the second cause of death worldwide. Colon cancer is third most common cancer and one of the few amenable to early diagnosis and treatment. Evaluation of factors affecting this cancer is important to increase survival time. Some of these factors affecting all diseases including cancer are social determinants of health. According to the importance of this disease and relation with these factors, this study was conducted to assess the relationship between social determinants of health and colon cancer survival. Materials and Methods: This was a cross-sectional, descriptive study for patients with colon cancer registered in the Cancer Research Center of Shahid Beheshti University of Medical Science, from April 2005 to November 2006, performed using questionnaires filled by telephone interview with patients (if patients had died, with family members). Data was analyzed with SPSS software (version 19) for descriptive analysis and STATA software for survival analysis including log rank test and three step Cox Proportional Hazard regression. Results: Five hundred fifty nine patients with ages ranging from 23 to 88 years with mean${\pm}$standard deviation of $63{\pm}11.8$ years were included in the study. The five year survival was 68.3%( 387 patients were alive and 172 patients were dead by the end of the study). The Cox proportional hazard regression showed 5-year survival was related to age (HR=0.53, p=0.042 for>50 years versus<50 years old) in first step, gender (HR=0.60, p=0.006 for female versus male) in second step, job (HR=1.7, p=0.001 for manual versus non manual jobs), region of residency (HR=3.49, p=0.018 for west versus south regions), parents in childhood (HR=2.87, p=0.012 for having both parents versus not having), anatomical cancer location (HR=2.16, p<0.033 for colon versus rectal cancer) and complete treatment (HR=5.96, p<0.001 for incomplete versus complete treatment). Conclusions: Social determinants of health such as job, city region residency and having parents during childhood have significant effects in 5-year survival of colon cancer and it may be better to consider these factors in addition to developing cancer treatment and to focus on these determinants of health in long-time planning.

SECTORAL CO-INTEGRATION AND THE ROLE OF AGRICULTURE IN BANGLADESH
Mohammad Ismail Hossain,Mst. Esmat Ara Begum,Eleni Papadopoulou,AnastasiosSemos 인하대학교 정석물류통상연구원 2012 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.10 No.3
This study estimates a Vector Error Correction Model (VECM) that incorporates the linkages among the agriculture, industry, construction, transport, storage and communication and service sectors for Bangladesh by using historical data from 1979 to 2009. Two cointegrating vectors confirm that all the different sectors moved together over the sample period, and therefore that their growth rates are interdependent. The long-run relationships of the industrial, construction, transport, storage and communication and service sectors to the agricultural sector were established, and the results show that the industrial and construction sectors contribute positively to the agricultural sector, the growing service sector contributes negatively and the transport, storage and communication sector shows mixed results. In addition, weak exogeneity for the agricultural sector is rejected and this underlines the fact that the agricultural sector should be considered by policymakers in any analysis of inter sector growth.

Fermented goat milk samples, processed by adding 0, 2, and 4% carob molasses, and Bifidobacterium bifidum DSMZ or Lactobacillus helveticus CH5, were evaluated for their physicochemical, antioxidative, and sensory properties along with probiotic viability during storage. pH and viscosity gradually decreased over the storage period whereas their values increased with the increased amount of carob molasses. Bifidobacterium bifidum DSMZ or Lactobacillus helveticus CH5 kept higher viable numbers. Lactobacillus helveticus CH5 strain recorded higher viability. Increasing the added amount of carob molasses increased the total phenolic content, which in turn is reflected in the increase in antioxidant activity. Adding carob molasses participated in the partial masking of the goaty flavor and had no significant effect on the product’s acceptability, which was strongly influenced by the progress of cold storage. Therefore, fermented goat milk described by its enhanced physicochemical and antioxidative properties could be obtained by adding carob molasses and probiotics.
