Purpose: The aims of this case-control study were to assess the correlation between some food habits in the last two decades and gastric cancer in East Azerbaijan of Iran. Materials and Methods: In this hospital based case control study, 616 patients (212 gastric cancer patients, 404 cancer free patients) were recruited. Food habits of patients over the past two decades were assessed with a structured questionnaire. We used conditional logistic regression analysis for estimating crude and adjusted odds ratios (OR) and their respective 95% confidence intervals (95%CI). Results: In this study, over-eating, consumption of high fat milk and yogurt and especial types of cheese increased the risk of gastric cancer (All<0.05). Consumption of such especial cheeses such as Koze and Khiki increased the risk of gastric cancer by 12.6 fold (95% CI:1.99-79.36) and 7.36 fold (95% CI:1.33-40.54), respectively. In addition, high fat food, moldy food, and pickled vegetables consumption as well as reuse of cooking oil for frying were significantly associated with gastric cancer risk. Furthermore, intake of Ghorme (deep fried meat) was positively correlated with gastric cancer risk (OR:1.31;95%CI: 0.91-1.87). Conclusions: It can be confirmed that particular food habits which have been very common in East-Azerbaijan in the last two past decades increase risk of gastric cancer. According to our results and taking into account the long latency period of gastric cancer it can be concluded that nutrition education for a healthy diet should be performed from early childhood. However, further well designed cohort studies are needed to achieve more clear results.
Quantum Duplex Coding for Classical Information on IBM Quantum Devices

Quantum duplex coding (QDC) allows the simultaneous two-way transmission of information between two communicating parties (Alice and Bob). We implement the QDC protocol on the IBM quantum device using QISkit and compare its performance with the ideal case. Our results indicate that while the noiseless case allows the simultaneous transmission of 1 bits/EPR in both directions, the noise in the IBM quantum devices limits the communication rate to 0.81 (0.75) bits/EPR from Alice (Bob) to Bob (Alice). We model this nonideal behavior of quantum gates on IBMquantum devices as ideal gates followed by the application of quantum noise to simulate QDC classically.

Objective: Uterine leiomyoma (UL), are noncancerous growths of the uterus that often appear during childbearing years and also called uterine fibroids. Recently, combination of ulipristal acetate (UPA) and high intensity focused ultrasound (HIFU) have been applied on UL treatment and cholecalciferol have been also suggested as a synergistic component but no pathway of efficacy was investigated. Herein, comparative proteome approach on leiomyoma cell line model was applied to investigate related pathways for UA treatment based on HIFU. Methods: Uterine leiomyoma cell line (GM10964) was treated with 10uM of ulipristal acetate (UPA) or with 10uM of UPA and 1uM of cholecalciferol(VitD3), respectively. After 24-hour incubation, cell was treated with 200W of HIFU using JC200D with home-made mount on transducer. And quantitative proteome analysis for each cell was performed using high resolution LC-MS platform. Results: Totally 5,286 proteins are identified among groups and gene ontology analysis showed that proteins which increased in HIFU combined with UPA and VitD3 were involved in mitochondrial metabolism, inferring apoptosis for cell death. Conclusion: Comparative proteome analysis revealed that combination of UPA and VitD3 on HIFU treatment for uterine leiomyoma showed the synergistic effect in term of apoptosis caused by mitochondrial metabolism.
Inter-industry Spillover of R&D, Technological Opportunities, and Productivity Growth
Somi Seong 서울대학교 경제연구소 1995 Seoul journal of economics Vol.8 No.1
This paper attempts to examine the empirical significance of the technological opportunities and spillover effects in the relationship between industrial R&D and productivity growth. Estimation results are in favor of the general hypothesis that a given level of investment in knowledge stock will have a greater effect in industries with relatively rich technological opportunities. However, The explicit consideration of the spillover effects does not lead to a significant improvement in estimation results. Analytically, as Scherer(1982) argues, spillover effects should play an important role in explaining output elasticity. but the results of empirical tests in this paper suggest that the information in the spillover effects is embodied in its own R&D.
