Background: A cancer registry program has been established in East Azerbaijan and this has emphasized the importance of cancers of gastrointestinal tract in this region. The aim of the present pathology-based cancer registry report is to renew epidemiologic aspects of gastrointestinal tract cancers and estimate recent trends. Materials and Methods: A survey team reviewed and collected all records of cancer cases from all referral and valid pathology laboratories of East Azerbaijan province during September 2007-2011. Crude rates, age-specific rates of cancer incidence and annual percent change were calculated. Results: The total newly diagnosed cancer cases (n=6,889)comprised 4,341 males (63.0%) and 2,540 females (36.9%). Gastric cancer was the most common GI tract cancer with an ASR (per $10^5$) of 23.1 for males and 7.69 for females. The ASRs for esophageal and colorectal cancers were 9.69 and 11.2 in males and 7.35 and 8.93 in females. Trend analysis showed a significant decline for esophageal cancer and increasing incidence for colorectal cancer in females. Conclusions: The prevalence of gastric cancer is high in East Azerbaijan province of Iran. This pathology based cancer registry showed an ascending trend for colorectal cancer and decreasing trend for esophageal cancer in females during 2007-2011.

Background: Knowledge regarding risk factors and primary signs of oral cancer in the general population can help them to avoid risky behaviour and seek timely advice from a physician. The aim of this study was to survey adult knowledge about risk factors and signs of oral cancer in Shiraz Dental University. Materials and Methods: In this descriptive cross-sectional study using an investigator-made questionnaire, 783 adults who were referred to Shiraz Dental University participated. Questionnaire data were analyzed by ANOVA and T-test. Results: The results showed that 32.3% of participants were aware of oral cancer and gained their knowledge from the media. The risk factors mentioned by these participants was as follows: sunlight 30.8%, hot and peppery food 40.7%, alcoholic drinks 47.4% and smoking 73.6% (there was significant relationship for drinking alcohol and gender, education and times of using dental service, p<0.05). They also mentioned the primary signs of oral cancer as follows: red patch without pain 27.8%, white patch without pain 13.5% and prolong scarring without pain 56.7% (there was significant relationship between these three signs and education and times of using dental service, p<0.05). The mean knowledge about the risk factors and signs of oral cancer were 1.94 from 5 with 1.14 standard deviation and 0.96 from 3 with 0.93 standard deviation. Conclusions: The observed low level of knowledge of people regarding both risk factors and signs of oral cancer emphasizes the need for more efforts to be made about the above mentioned issues by the media.

Background: MMP-3 is a proteolytic enzyme of the matrix metalloproteinase family. Protein degradation which is their fundamental action regulates different activities of tumor cell such as their growth, differentiation, apoptosis, migration, invasion, angiogenesis as well as their resistance to the immune system. Aim: The aim of this study was to determine MMP-3 serum levels in patients with OSCC and investigate if they correlate with clinicopathological features. Method and materials: Using an ELISA kit, we assessed and compared the circulating levels of MMP-3 in blood serum of 45 oral squamous cell carcinoma patients with 45 healthy control samples. Results: The serum MMP-3 level in OSCC patients was significantly higher ($9.45{\pm}4.6$ ng/ml) than healthy controls ($5.9{\pm}3.6$ ng/ml, p<0.001), especially in females and in older patients. However, there was no apparent correlation in serum MMP-3 concentration with the clinico-pathological features such as tumor location, stage, tumor size, nodal status, distant metastasis, histological grade and smoking. Discussion: This result suggests that the measurement of serum MMP-3 concentration might be helpful to diagnose OSCC but not to predict prognosis.

Background: This study aimed to show the localization of estrogen / progesterone receptors, human epidermal growth factor receptor 2 (Her-2) and protein 53 (p53) by immunohistochemistry in a series of consecutive breast cancer patients. Materials and Methods: The study covered invasive breast cancers from 299 patients presenting at the Oncogenetic Clinic and Pathology Centers of Ahwaz Jondishapour University of Medical Sciences Hospital in Iran during the time period from 2009 to 2011. The Scarff-Bloom Richardson scoring method was used. Results: Of the 299, 27% (80/299) were <40, 33% (100/299) were 41-50, and the remaining 40% (119/299) were>50 years old. The highest incidence of breast cancer in this study population was in the group of more than 50 year age, and the most common histological type of breast cancer was the invasive ductal carcinoma, which accounted for 68% (203/299) of the cases. Out of possible total of 207, 6% (13/207), 41% (85/207), and 53% (109/207) were scored as grade I, II, III, respectively. Conclusion: Our findings demonstrated a lack of association between labeling for the markers studied and tumor size and age of the patients. We confirmed an association between ER labeling and nuclear grade of breast cancer. The conflicting results obtained compared with the literature be because of differences in the immunohistochemical techniques applied in the various studies and to the scoring systems used.

In this work, the buckling analysis of material sandwich plates based on a two-parameter elastic foundation under various boundary conditions is investigated on the basis of a new theory of refined trigonometric shear deformation. This theory includes indeterminate integral variables and contains only four unknowns in which any shear correction factor not used, with even less than the conventional theory of first shear strain (FSDT). Applying the principle of virtual displacements, the governing equations and boundary conditions are obtained. To solve the buckling problem for different boundary conditions, Galerkin's approach is utilized for symmetric EGM sandwich plates with six different boundary conditions. A detailed numerical study is carried out to examine the influence of plate aspect ratio, elastic foundation coefficients, ratio, side-to-thickness ratio and boundary conditions on the buckling response of FGM sandwich plates. A good agreement between the results obtained and the available solutions of existing shear deformation theories that have a greater number of unknowns proves to demonstrate the precision of the proposed theory.

Background: Genetic alterations in gliomas have increasing importance for classification purposes. Thus, we are especially interested in studying IDH mutations which may feature potential roles in diagnosis, prognosis and response to treatment. Our aim was to investigate IDH mutations in diffuse glioma patients diagnosed in university hospital centre of Fez in Morocco. Materials and Methods: IDH1 codon 132 and IDH2 codon 172 were direct-sequenced in 117 diffuse glioma samples diagnosed and treated in University Hospital Hassan II between 2010 and 2014. Results: The R132H IDH1 mutation was identified in 43/117 tumor samples and R172K IDH2 mutation was detected in only one anaplastic oligodendroglioma. IDH mutations were observed in 63.2% of astrocytomas, 73.3% of diffuse oligodendrogliomas and 12.90% of glioblastomas. Conclusions: Our results confirmed other studies published earlier for other populations with some small discrepancies.

Objective: In vitro fertilization (IVF) is a well-known method for the treatment of infertility. The present study aimed to compare the differences between infertile women with successful and unsuccessful IVF outcomes regarding the expression of T helper (Th) cell transcription factors and a group of related cytokines before and after exposure to their husbands' seminal plasma. Methods: This study was performed on 19 couples with unexplained infertility undergoing IVF treatment. Among the studied group, nine and 10 couples had successful and unsuccessful IVF outcomes, respectively. This study was carried out using real-time polymerase chain reaction. Results: Before seminal plasma exposure, the expression levels of T-bet (p< 0.007), $interferon-{\gamma}$ (p= 0.013), and tumor necrosis factor $(TNF)-{\alpha}$ (p= 0.017) were higher in the infertile women with IVF failure than in those with successful IVF outcomes, while those of GATA3 (p< 0.001), Foxp3 (p= 0.001), and interleukin (IL)-35 (p< 0.003) were lower. After seminal exposure, the expression of T-bet (p= 0.02), Rorc (p< 0.001), $TNF-{\alpha}$ (p= 0.001), Foxp3 (p= 0.02), and $interferon-{\gamma}$ (p= 0.001) increased in the unsuccessful IVF group, while the expression of Foxp3 (p= 0.02), Rorc (p< 0.001), IL-23 (p= 0.04), IL-17 (p= 0.02), IL-6 (p< 0.001), transforming growth $factor-{\beta}$ (p= 0.01), and IL-35 (p< 0.001) increased in the successful IVF group. Conclusion: In summary, IVF failure was associated with imbalanced Th1/Th2/Th17/Treg responses. Moreover, our results show that seminal plasma might have a positive effect on IVF outcomes via changes in peripheral blood T cell subsets.

PURPOSE. The purpose of this study was to compare the coronal bone level and patient satisfaction in 1-implant and 2-implant assisted mandibular overdentures. MATERIALS AND METHODS. Twenty patients who had maladaptive mandibular dentures were treated in this study. Patients were randomly divided into two groups. The first group received 1 implant (Simple line II, Implantium, South Korea) in their mandibular midline and the second group received 2 implants in their B and D regions (according to Misch's category). If the primary stability of each implant was at least 60 ISQ, ball attachment was placed and denture relined with soft liner. After 6 weeks, retentive cap incorporated with hard acrylic resin. In the 6 and 12 months recalls, periapical digital radiograph were made and visual analogue scale questionnaires were used to record patient satisfaction. The Friedman test was done for comparing the presurgical and postsurgical parameters in each group and the U-Mann Whitney test (P<.05) was done for comparison of post-treatment results between the two groups. RESULTS. All implants achieved sufficient primary stability to be immediately loaded. Patient satisfaction was high, and there were no significant differences between two groups (P>.05). In addition, mean marginal bone loss was $0.6{\pm}0.67$ mm in the first group and $0.6{\pm}0.51$ mm in the second group, after 12 month. Mean marginal bone loss showed no significant differences between two groups. CONCLUSION. This preliminary one-year result indicated that mandibular overdentures anchored to a single implant can be a safe and cost-effective method as a starting step for implant-overdenture treatment.
