2Methylenetetrahydrofolate reductase C677T genotype affects promoter methylation of tumor-specific genes in sporadic colorectal cancer through an interaction with folate/vitamin B_(12) status显示文摘AIM:To evaluate joint effects of Methylentetra-hydrofolate reductase(MTHFR) C677T genotypes,and serum folate/vitamin B12 concentrations on promoter methylation of tumor-associated genes among Iranian colorectal cancer patients. METHODS:We examined the associations between MTHFR C677T genotype,and promoter methylation of P16,hMLH1,and hMSH2 tumor-related genes among151 sporadic colorectal cancer patients. The promoter methylation of tumor-related genes was determined by methylation-specific PCR. Eighty six patients from whom fresh tumor samples were obtained and 81 controls were also examined for serum folate and vitamin B12 concentrations by a commercial radioimmunoassay kit. RESULTS:We found 29.1% of cases had tumors with at least one methylated gene promoter. In case-case comparison,we did not find a significant association between methylation in tumors and any single genotype. However,in comparison to controls with the CC genotype,an increased risk of tumor methylation was associated with the CT genotype(OR = 2.5;95% CI,1.1-5.6) . In case-case comparisons,folate/vitamin B12 levels were positively associated with tumor methylation. Adjusted odds ratios for tumor methylation in cases with high(above median) versus low(below median) serum folate/vitamin B12 levels were 4.9(95% CI,1.4-17.7) ,and 3.9(95% CI,1.1-13.9) ,respectively. The frequency of methylated tumors was significantly higher in high methyl donor than low methyl donor group,especially in those with MTHFR CT(P = 0.01) ,and CT/TT(P = 0.002) genotypes,but not in those with the CC genotype(P = 1.0) . CONCLUSION:We conclude that high concentrations of serum folate/vitamin B12 levels are associated with the risk of promoter methylation in tumor-specific genes,and this relationship is modified by MTHFR C677T genotypes.Pooneh Mokarram Fakhraddin Naghibalhossaini Mehdi Saberi Firoozi Seyed Vahid Hosseini Ahmad Izadpanah Heshmetalah Salahi Seyed Ali Malek-Hosseini Abdoulrasool Talei Mehra Mojallal 2008World Journal of Gastroenterology2008,14,23:5
3Comparison among Ocular Response Analyzer,Corvis ST and Goldmann applanation tonometry in healthy children显示文摘AIM: To explore the relationship between different parameters of Ocular Response Analyzer(ORA) and Corvis ST(CST) in a sample of healthy Iranian school-aged children and the relationship between parameters of these 2 instruments against intraocular pressure(IOP), measured by the Goldmann applanation tonometer(GAT-IOP), age and gender, and find possible correlation between ORA and CST with GAT.METHODS: This cross-sectional study included 90 healthy children. A general interview and complete eye examination were performed. Following successful GATIOP measurement, ORA and CST were conducted. The CST parameters were A 1/2 length(A1 L, A2 L), A 1/2 velocity(A1 V, A2 V), highest concavity deformation amplitude(HCDA), radius of curvature(Ro C), peak distance(PD), central corneal thickness(CCT) and IOP. The ORA parameters were corneal hysteresis(CH), corneal resistance factor(CRF), Goldmann-correlated IOP(IOP-G) and corneal compensated IOP(IOP-CC). Extracted data was analyzed using the Statistical Package for Social Science software.RESULTS: Totally 39 males with age of 9.08±1.60(6-12)y and 51 females with age of 8.96±1.55(6-13)y were included. Many CST parameters were significantly correlated with CH, CRF, IOP-G and IOP-CC. Some CST parameters had a significant correlation with GAT-IOP, including IOP-CST in both eyes and HCDA, A2 L, PD, and RoC in the left eye, but none with age, except A2 L in the right eye. The CRF measurement showed a significant correlation with GAT-IOP in both eyes and CH in the right eye, yet, none with age. Among all CST and ORA parameters, CCT-CST in both eyes and A1 L in right eye had a significant correlation with gender, although this was a negligible negative correlation. Comparison of mean IOP values by different devices showed a significantly highest IOP overestimation by CST and lowest by IOP-CC compared with GAT. Also, IOP-G versus IOP-CST significantly had the lowest IOP overestimation among others. Overall, either low positive correlation or negligible correlation was found between IOP measurements by 3 instruments.CONCLUSION: The study finds the highest IOP overestimation by CST and lowest by IOP-CC compared with GAT. Overall, either low positive correlation or negligible correlation is found between IOP measurements by the 3 instruments.Ramin Salouti Ali agha Alishiri Reza Gharebaghi Mostafa Naderi Khosrow Jadidi Ahmad Shojaei-Baghini Mohammadreza Talebnejad Zahra Nasiri Seyedmorteza Hosseini Fatemeh Heidary 2018International Journal of Ophthalmology(English edition)2018,11,8:4
4Use of amino silane coupling agent to improve physical and mechanical properties of UF-bonded wheat straw(Triticum aestivum L.) poplar wood particleboard显示文摘We evaluated the potential use of amino silane coupling agent(Si NH) to improve physical and mechanical properties of UF-bonded wheat straw(Triticum aestivum L.) poplar wood particleboard. We examined the effects of varied content of silane coupling agent content and ratios of straw to poplar wood particles on particleboard properties. The ratios of straw to poplar wood particles were100:0, 85:15, 70:30 and 55:45. Silane coupling agent content was tested at three levels, 0, 5 and 10 %. The experimental panels were tested for their mechanical strength, including modulus of elasticity(MOE), modulus of rupture(MOR), internal bonding(IB) and physical properties according to procedures specified in DIN 68763(Chipboard for special purposes in building construction:concepts, requirements, testing, 1982–03, 1982). All board properties were improved by the addition of silane coupling agent. The use of poplar wood particles had a positive effect on the mechanical properties of wheat straw particleboard but had a negative effect on physical properties(thickness swelling and water absorption).Seyedeh Masoumeh Hafezi Aliakbar Enayati Kazem Doost Hosseini Asghar Tarmian Sayed Ahmad Mirshokraii 2016Journal of Forestry Research2016,27,2:3
5Preparation, characterization, and antibacterial activity of γ-irradiated silver nanoparticles in aqueous gelatin显示文摘Colloidal silver nanoparticles (Ag-NPs) were obtained through γ-irradiation of aqueous solutions containing AgNO 3 and gelatin as a silver source and stabilizer, respectively. The absorbed dose of γ-irradiation influences the particle diameter of the Ag-NPs, as evidenced from surface plasmon resonance (SPR) and transmission electron microscopy (TEM) images. When the γ-irradiation dose was increased (from 2 to 50 kGy), the mean particle size was decreased continuously as a result of γ-induced Ag-NPs fragmentation. The antibacterial properties of the Ag-NPs were tested against Methicillinresistant Staphylococcus aureus (MRSA) (Gram-positive) and Pseudomonas aeruginosa (P.a) (Gram-negative) bacteria. This approach reveals that the γ-irradiation-mediated method is a promising simple route for synthesizing highly stable Ag-NPs in aqueous solutions with good antibacterial properties for different applications.Majid Darroudi Mansor B.

19Weibel Instability Growth Rate in Magnetized Plasmas with Quasi-Relativistic Distribution Function显示文摘The mechanism of the Weibel instability is investigated for dense magnetized plasmas. As we know, due to the electron velocity distribution, the Coulomb collision effect of electron-ion and the relativistic properties play an important role in such study. In this study an analytical expression for the growth rate and the condition of restricting the Weibel instability are derived for low-frequency limit. These calculations are done for the oscillation frequency dependence on the electron cyclotron frequency. It is shown that, the relativistic properties of the particle lead to increasing the growth rate of the instability. On the other hand the collision effects and background magnetic field try to decrease the growth rate by decreasing the temperature anisotropy and restricting the particles movement.Sayed Ahmad Hosseini Mohammad Mahdavi 2016Communications in Theoretical Physics2016,65,12:0
20Birds and poultries toxoplasmosis in Iran: A systematic review and meta-analysis显示文摘Objective: To evaluate the overall prevalence of Toxoplasma gondii infection among birds and poultries in Iran. Methods: Data were systematically collected from 1983 to 2016 in Iran on the following electronic databases: Pub Med, Google Scholar, Science Direct, Scopus, Web of Science, Magiran, Irandoc, Iran Medex, and Scientific Information Database. Additionally, the abstracts of national scientific congresses and dissertations were included. Results: A total of 20 articles in the field of birds and poultries toxoplasmosis, totally examining 4 563 cases with 754 positive results reporting the overall prevalence of infection from all parts of Iran could fulfill our eligibility criteria. The overall estimated prevalence included in chicken 20%(95% CI: 3% to 38%) in chicken, pigeons 8%(95% CI:-17% to 33%) and in sparrows 15%(95% CI:-25% to 54%). Conclusion: Although there is a lack in data about poultries and birds toxoplasmosis in Iran, our meta-analysis revealed that infection rate is high among birds and poultries in Iran. More studies are needed to manage controlling programs and prevention strategies among poultries in Iran.Azar Shokri Mehdi Sharif Saeed Hosseini Teshnizi Shahabeddin Sarvi Mohammad-TaghiRahimi Azadeh Mizani Ehsan Ahmadpour Mahboobeh Montazeri Ahmad Daryani 2017Asian Pacific Journal of Tropical Medicine2017,10,7:0
