| 1 | Association of vascular endothelial growth factor-634G/C and receptor for advanced glycation end products G82S gene polymorphisms with diabetic retinopathy显示文摘AIM: To investigate the association of receptor for advanced glycation end products(RAGE) G82S and vascular endothelial growth factor(VEGF)-634 G/C gene polymorphisms with diabetic retinopathy(DR).METHODS: Our cross-sectional study included 61 diabetic patients, 12 of them had proliferative diabetic retinopathy(PDR), 15 had non proliferative diabetic retinopathy(NPDR), 34 had no diabetic retinopathy(NDR)and 61 healthy controls. Participants were tested for RAGE G82S and VEGF-634 G/C polymorphisms by polymerase chain reaction-restriction fragment length polymorphism.RESULTS: We found a significant association between VEGF-634 G/C polymorphism and PDR as PDR patients had increased incidence of VEGF-634 CC genotype compared to NDR patients [odds ratio for CC vs(GC +GG)=6.5, 95% CI=1.5-27.8, P =0.021]. Also VEGF-634 CC genotype and C allele were significantly higher in the PDR than in NPDR patients, which is a novel finding in our study(P =0.024, 0.009 respectively). The mean triglycerides level was significantly higher in diabetic patients with CC genotype(P =0.01) as compared to patients with other genotypes. All cases and control subjects were of the same heterozygous RAGE 82G/S genotype.CONCLUSION: Patients carrying VEGF-634 C polymorphism have a higher risk of PDR development,so VEGF-634 G/C polymorphism could be used as a predictive marker for PDR in diabetic patients. We could not find a significant association between RAGE G82S polymorphism and DR. | Asmaa Kamal Khaled Abu Eleinen Ibrahem Siam | 2016 | International Journal of Ophthalmology(English edition)2016，9，8： | 2 |
| 2 | Microfracture Characterization in Sandstone Reservoirs:A Case Study from the Upper Triassic of Syria's Euphrates Graben显示文摘The Euphrates Graben is located in eastern Syria.The Upper Triassic Mulussa F Formation sandstones serve as the primary reservoir intervals in the majority of the graben fields.The study’s findings were based on core studies:petrographic examination of thin sections,scanning electron microscope(SEM),imaging of backscatter scanning electron microscope(BSE),X-ray microprobe examinations,and carbon-oxygen stable isotope analysis of microfracture-filling cements.Three of the most common types of microfracture found in the investigated sandstones are intragranular or intracrystalline microfractures,grain boundary or grain-edge microfractures,and transgranular(crossing grains)microfractures.Sandstone microfractures that are open and free of secondary mineralization improve sandstone storage and permeability.However,microfractures that are cemented and filled with secondary mineralization reduce storage and permeability.Common siderite and pyrite cements were identified within the microfractures and the nearby sandstone matrix.Larger anhedral or euhedral siderites are thought to form during shallow burial diagenesis,whereas poikilotopic siderites are thought to form during deep burial diagenesis.Poikilotopic pyrite is believed to be a diagenetic cement,which is attributed to the reduction of iron oxides present in the sediments in the presence of hydrocarbons.Microfractures reflect tectonic,overpressure,and diagenetic origins.Microfractures of tectonic origin are associated with folding and thrust activities over the Euphrates Graben area,and they were formed at the beginning of the Upper Triassic with siderite and pyrite cement equilibration temperatures of approximately 100–105℃,and they continued forming from the middle to the end of the Upper Triassic with cement equilibration temperatures of approximately 90–100℃in conjunction with the first phase of the Euphrates Graben.Microfractures related to diagenetic and overpressure processes are tension microfractures and were formed in compression settings during the Upper Triassic. | Ibrahem Yousef Vladimir Morozov Vladislav Sudakov Ilyas Idrisov | 2022 | Journal of Earth Science2022，33，4： | 2 |
