- چکیده انگلیسی: Background: The purpose of this study was to assess the incidence and importance of bony bridge that covers the
supra scapular notch during posterior approach to transfer accessory nerve to suprascapular nerve.
Methods: Between 2010 and 2015, the frequency and importance of suprascapular bony bridge instead of transverse
ligament was assessed among patients with brachial plexus injury candidate to shoulder function restoration by
accessory to suprascapular nerve transfer through posterior approach.
Results: Forty three patients, 41 male and 2 female, (mean age: 32.5 years, range 14 to 36) were included in this
study. Five male patients (11.6%) had a complete bony rim on the superior scapular notch. Suprascapular nerve
release needed osteotomy of the bony bridge and related equipment.
Conclusion: Although all previous cadaveric studies among different ethnic groups had reported the prevalence
between 0.3 to 30% of suprascapular canal, this in vivo study showed the incidence of 11.6%. Preoperative alertness
about this variation could make the exploration and release of the suprascapular nerve easier and reduce the risk of
nerve injury or failing to anatomize it.- انتشار مقاله: 28-09-1396

- چکیده:
- چکیده انگلیسی: Introduction: Presenting a case with repeated episodes of flat Anterior Chamber (AC) after Ahmed valve implantation, and suggesting a simple suturing procedure to manage these recurrences.
Case:A 65-year-old woman presented to our clinic with uncontrolled Neovascular Glaucoma (NVG) in her left eye due to advanced Proliferative Diabetic Retinopathy (PDR) despite full medication to reduce Intraocular Pressure (IOP). After Ahmed valve implantation, anterior chamber became flattened spontaneously on postoperative day one. Therefore, we filled the AC with air at the first attempt but this procedure failed a day later. Then, we filled the AC with an ocular viscoelastic device. Because of these procedures failed to keep the AC formed, we hypothesized that it may be a malfunctioned valve. Therefore, we inserted 5-0 Nylon in Ahmed tube through AC and fixed it to the subconjunctiva two days after the second procedure. Anterior chamber remained deep and its shallowing did not occur despite removing the suture two weeks after the insertion. The IOP was controlled well with a functional filtering device at the last follow–up visit four months after the surgery.
Conclusion: Spontaneous episodes of flat AC after Ahmed valve implantation in an eye can be well managed by inserting a removable suture into the Ahmed valve tube.- انتشار مقاله: 19-07-1393

- چکیده:
- چکیده انگلیسی: Background& Aims: Gastric adenocarcinoma has been considered as an infectious disease since 1994, when the Helicobacter pylori (H. pylori) infection categorized as a definite class I human carcinogen. H. pylori uses extensive numbers of virulence factors to overcome host defence mechanisms. One independent H. pylori factor that plays an important role in determining H.pylori pathogenesisis vacuolating cytotoxin A(vacA).The purpose of this study was to investigate the frequency of vacA Genotypes, and also its association with disease outcome in infected patients. Methods: Antral gastric biopsy materials were collected from 88 patients with different gastroduodenal diseases. Genotyping of the VacA alleles were determined by PCR methods. Results: Of 64 H.pylori positive patients, 38 were classified as gastritis, 11 as peptic ulcer, and 15 as gastric adenocarcinoma. Four Vac A genotypes were observed, including 20 (22.7%) for s1/m2 (with frequency of relatively equal in all groups), 12 (13.6%) for s1m1 (with the highest frequency in gastric adenocarcinoma and peptic ulcer), 7 (7.95%) for s2m2 (with the highest frequency in gastritis( and 3 (3.4%) for s2m1 (with the highest frequency in peptic ulcer). Conclusion: In this study, no significant relationship was observed between the different genotypes of the vacA and the clinical outcome. Gastric adenocarcinoma also showed significant association with age and gender.

- چکیده:
- چکیده انگلیسی: With increasing use of e-banking system in Iranian banking sector, ignoring the issue of fraud in the system will be very costly for banks and e-banking customers. Fraud in e-banking is due to some security problems (such as weakness in access control systems and inadequate internal control). So, identifying success factor in fraud prevention in e-banking can be useful for e-banking system developers to improve these systems security. In this paper we have tried to identify and rank these success factors for fraud prevention in e-banking systems. For this purpose, we first review the literature to find potential factors, then identified factors were weighted by using fuzzy group multi criteria decision-making model and experts' judgment. The results show that for elimination fraud in e-banking systems it is necessary to pay attention to technical, operational, strategic and financial factors respectively

- چکیده:
- چکیده انگلیسی: Supply and development of ICT is considered as an important factor of ICT demand in line of macro plan of each country. In this regard, the relationship development of provinces with ICT services and ICT infrastructure is investigated among households of provinces in the Iran. In order to evaluate the level of ICT services and infrastructure, we applied introduced "IDI International index" with three separate subgroups (access, use, skills). The estimate results show; by increasing size of household, demand for ICT will be grown up. Also household are following from last year consumption habits. In evaluating the relationship development of ICT services and ICT infrastructures, skills subgroup has had most effect on growing of household expenditure on ICT. As a result investment on user skills level increases usage of ICT facilities. Finally access subgroup that was related to investment in ICT infrastructure and facilities causes more growth in ICT demand.

- چکیده:
- چکیده انگلیسی: Taking into account the economic capabilities, competitive advantages and environment dynamics, this research presents a new physical flow optimization model by considering payment period, time value of money and exchange rate fluctuations. Considering the actual circumstances of the current case study in the global value chain, a single-objective non-linear mathematical model is presented for the role of the SIBA MOTOR Company. Owing to the non-linear nature of the presented model, it has been linearized through a heuristic method. Next, by using GAMS software, the model is solved by considering the assumption of the case study. Finally, a sensitivity analysis is performed on important parameters after obtaining the numerical results to assess them. Appropriate potential location of the factory, inventory of each period, CKDs and CBUs flow of vehicles, the amount of tax and the customs expenses, and each payment method’s share, are some of the outputs of the model. The results of the proposed model are appropriate for the Iranian automotive companies to participate more actively in the global value chains of the automotive industry.

- چکیده:
- چکیده انگلیسی: In this study, both the presence and concentration of some unsaturated compounds in hexane extracts of different parts of Anthemis talyschensis showing absorption at wavelength 280-450 nm were surveyed, with the view of possibly using extracts of this plant in new formulations of sunscreen creams. The hexane extracts of flower, leaf and stem of A. talyschensis, collected from Northwest Iran, were obtained using a Soxhlet apparatus. The fatty acids were derivatized to methyl esters and were determined by gas chromatography/flame ionization detector (GC/FID) and gas chromatography/mass spectrometry (GC/MS) systems. The chemical analysis resulted in identification of 14, 9 and 29 constituents, comprising about 99.5, 97.1 and 98.2% of the total constituents in hexane extracts of flower, leaf and stem, respectively. The main unsaturated constituents in the hexane extract of A. talyschensis flower were 9, 12-octadecadienoic acid, 9-octadecenoic acid and 6, 9, 12-octadecatrienoic acid; while the leaf's extract contained 9, 12-octadecadienoic acid and 9-octadecenoic acid; no unsaturated compounds were detected in the stem. The ratios of unsaturated fatty acid /saturated fatty acid were 13.6, 9.3 and 0 in extracts of the flower, leaf and stem, respectively, but the total amounts in the leaf were much greater. It can be concluded the leaf extract is more likely to be suitable for producing sunscreens creams than others.
