3Relationship between vitamin D and IL-23,IL-17 and macrophage chemoattractant protein-1 as markers of fibrosis in hepatitis C virus Egyptians显示文摘AIM:To assess vitamin D in hepatitis C patients and its relationship to interleukin (IL)-23, IL-17, and macrophage chemoattractant protein-1 (MCP-1). METHODS:The study was conducted on 50 Egyptian hepatitis C virus (HCV) genotype number IV-infected patients and 25 ageand gender-matched healthy subjects. Venous blood samples were obtained. Samples were allowed to clot and sera were separated by centrifugation and stored at -20 ℃. A 25 hydroxy vitamin D assay was carried out using solid phase RIA. A 1,25 dihydroxy vitamin D assay was carried out using a commercial kit purchased from Incstar Corporation. IL-17 and -23 and MCP-1 were assayed by an enzyme immunoassay. Quantitative and qualitative polymerase chain reaction for HCV virus were done by TaqMan technology. Only HCV genotype IV-infected subjectswere included in the study. The mean ± SD were determined, a t-test for comparison of means of different parameters was used. Correlation analysis was done using Pearson's correlation. Differences among different groups were determined using the Kruskal-Wallis test. RESULTS:The mean vitamin D level in HCV patients (groupⅠ) was 15 ± 5.2 ng/mL while in control (group Ⅱ) was 39.7 ± 10.8. For active vitamin D in groupⅠas 16.6 ± 4.8 ng/mL while in group Ⅱ was 41.9 ± 7.9. IL-23 was 154 ± 97.8 in group Ⅰ and 6.7 ± 2.17 in group Ⅱ. IL-17 was 70.7 ± 72.5 in cases and 1.2 ± 0.4 in control. MCP-1 was 1582 ± 794.4 in group Ⅰand 216.1 ± 5.38 in group Ⅱ. Vitamin D deficiency affected 72% of HCV-infected patients and 0% of the control group. Vitamin D insufficiency existed in 28% of HCV-in-fected patients and 12% of the control group. One hundred percent of the cirrhotic patients and 40% of non cirrhotic HCV-infected patients had vitamin D deficiency. IL-23, IL-17, and MCP-1 were markedly increased in HCV-infected patients in comparison to controls.A significant negative correlation between vitamin D and IL-17 and-23 and MCP-1 was detected. HCV-infected males and females showed no differences with respect to viral load, vitamin D levels, IL-17, IL-23 and MCP-1. The viral load was negatively correlated with vitamin D and active vitamin D (P = 0.0001 and P = 0.001, respectively), while positively correlated with IL-23, IL-17, and MCP-1. We classified the patients according to sonar findings into four groups. Group Ⅰa with bright hepatomegaly and included 14 patients. Group Ⅰb with perihepatic fibrosis and included 11 patients. Group Ⅰc with liver cirrhosis and included 11 patients. Group Ⅰd with he patocellular carcinoma (HCC) and included 14 patients. Vitamin D and active vitamin D were shown to be lower in cirrhotic patients and much lower in patients with HCC, and this difference was highly significant (P = 0.0001). IL-17 and-23 and MCP-1 were higher in advanced liver disease) and the differences were highly significant (P = 0.0001).CONCLUSION:Whether the deficiency of vitamin D is related to HCV-induced chronic liver disease or predisposing factor for higher viral load is a matter of debate.Noha M El Husseiny Hala M Fahmy Waleed A Mohamed Hisham H Amin 2012World Journal of Hepatology2012,4,8:12
4SMILE intraoperative complications: incidence and management显示文摘AIM: To report the intraoperative complications associated with small incision lenticule extraction(SMILE) and their management. METHODS: This was a retrospective consecutive interventional clinical study, carried out on patients with myopia and myopic astigmatism, who underwent SMILE procedure. Type of intraoperative complications and their management were recorded. RESULTS: Our study comprised 282 eyes of 141 patients who were enrolled for SMILE surgeries. The intraoperative complications included lost vacuum(18 eyes, 6.38%), treatment decentration(6 eyes, 2.12%), wound bleeding(21 eyes, 7.45%), incomplete bubble separation(black islands)(3 eyes, 1.06%), the epithelial defects(15 eyes, 5.32%). Incision tear(27 eyes, 9.57%), lenticule adherence to the cap(6 eyes, 2.12%), and cap perforation occurred in 2 eyes(0.7%). CONCLUSION: Although SMILE is a promising technique for the correction of myopia and myopic astigmatism with predictable, efficient, safe refractive and visual outcomes, complications can occur. However, most of them are related to inexperience and are included in the learning curve of the technique. More studies with a bigger number of eyes are required to efficiently evaluate the intraoperative complications and standardize their management strategies.Abdelmonem M Hamed Mohamed Amin Heikal Tarek T.Soliman Ahmed Daifalla Khaled E Said-Ahmed 2019International Journal of Ophthalmology(English edition)2019,12,2:4
5Effects of the nitrification inhibitor nitrapyrin and tillage practices on yield-scaled nitrous oxide emission from a maize field in Iran显示文摘Nitrification inhibitors can effectively decrease nitrification rates and nitrous oxide(N_(2)O)emission while increasing crop yield under certain conditions.However,there is no information available on the effects of nitrification inhibitors and tillage practices on N_(2)O emissions from maize cropping in Iran.To study how tillage practices and nitrapyrin(a nitrification inhibitor)affect N_(2)O emission,a split factorial experiment using a completely randomized block design with three replications was carried out in Northeast Iran,which has a cold semiarid climate.Two main plots were created with conventional tillage and minimum tillage levels,and two nitrogen(N)fertilizer(urea)management systems(with and without nitrapyrin application)were created as subplots.Tillage level did not have any significant effect on soil ammonium(NH_(4)^(+))and nitrate(NO_(3)^(-))concentrations,cumulative amount and yield-scaled N_(2)O emission,and aboveground biomass of maize,whereas nitrapyrin application showed significant effect.Nitrapyrin application significantly reduced the cumulative amount of N_(2)O emission by 41%and 32%in conventional tillage and minimum tillage practices,respectively.A reduction in soil NO_(3)^(-)concentration by nitrapyrin was also observed.The average yield-scaled N_(2)O emission was 13.6 g N_(2)O-N kg^(-1)N uptake in both tillage systems without nitrapyrin application and was significantly reduced to 7.9 and 8.2 g N_(2)O-N kg^(-1)N uptake upon the application of nitrapyrin in minimum tillage and conventional tillage practices,respectively.Additionally,nitrapyrin application increased maize biomass yield by 4%and 13%in the minimum tillage and conventional tillage systems,respectively.Our results indicate that nitrapyrin has a potential role in reducing N_(2)O emission from agricultural systems where urea fertilizers are broadcasted,which is common in Iran due to the practice of traditional farming.Azam BORZOUEI Ulo MANDER Alar TEEMUSK Alberto SANZ-COBENA Mohammad ZAMAN Dong-Gill KIM Christoph MÜLLER Ali Askary KELESTANIE Parvaneh SAYYAD AMIN Ebrahim MOGHISEH Khadim DAWAR Ana Gabriela PÉREZ-CASTILLO 2021Pedosphere2021,31,2:4
6Barrett's esophagus:Prevalence and risk factors in patients with chronic GERD in Upper Egypt显示文摘AIM:To determine the prevalence and possible risk factors of Barrett's esophagus(BE) in patients with chronic gastroesophageal reflux disease(GERD) in El Minya and Assuit, Upper Egypt.METHODS:One thousand consecutive patients with chronic GERD symptoms were included in the study over 2 years.They were subjected to history taking including a questionnaire for GERD symptoms, clinical examination and upper digestive tract endoscopy.Endoscopic signs suggestive of columnar-lined esophagus(CLE) were defined as mucosal tongues or an upward shift of the squamocolumnar junction.BE was diagnosed by pathological examination when specialized intestinal metaplasia was detected histologically in suspected CLE.pH was monitored in 40 patients.RESULTS:BE was present in 7.3% of patients with chronic GERD symptoms, with a mean age of 48.3 ± 8.2 years, which was signif icantly higher than patients with GERD without BE(37.4 ± 13.6 years).Adenocarcinomawas detected in eight cases(0.8%), six of them in BE patients.There was no signiflcant difference between patients with BE and GERD regarding sex, smoking, alcohol consumption or symptoms of GERD.Patients with BE had significantly longer esophageal acid exposure time in the supine position, measured by pH monitoring.CONCLUSION:The prevalence of BE in patients with GERD who were referred for endoscopy was 7.3%.BE seems to be associated with older age and more in patients with nocturnal gastroesophageal reflux.Yasser M Fouad Madiha M Makhlouf Heba M Tawfik Hussein El Amin Wael Abdel Ghany Hisham R El-khayat 2009World Journal of Gastroenterology2009,15,28:4

8GIS-based irrigation water management for precision farming of rice显示文摘Precision farming aims to manage production inputs over many small management zones rather than on large zones.It is difficult to manage inputs at extremely fine scales,especially in the case of the rice irrigation system.However,site-specific irrigation management can potentially improve the overall water management in comparison to irrigated areas of hundreds of hectares.A critical element of the irrigation scheduling and management is the accurate estimation of irrigation supplies and its proper allocation for the irrigation offtake structures based on the actual planted areas.All irrigation scheduling procedures consist of monitoring indicators that determine the need for irrigation.The final decision depends on the irrigation criterion,strategy and goal.Irrigation scheduling is the decision of when and how much water to apply to a field.The amount of water applied is determined by using a criterion to determine irrigation need and a strategy to prescribe how much water to apply in any situation.The right amount of daily irrigation supply and monitoring at the right time within the discrete irrigation unit is essential to improve the irrigation water management of a scheme.This paper presents the GIS capability to achieve the goal in the view of irrigation strategy and goal with special reference to precision farming of rice.The GIS-based water management model was developed for the scheduling daily irrigation water deliveries and regular monitoring of irrigation delivery performance.The“Scheduling”program computes the right amount of irrigation deliveries based on crop water requirements.The“Monitoring”program gives information on the uniformity of water distribution and the shortfall or excess.The displayed results allow the manager to view maps,tables and graphs in a comprehensible form to ease decision making that where the irrigation amount will be delivered as the season progresses.GIS was used as a useful tool to assist the irrigation water management program in the context of precision farming.Rowshon M K Amin M S M 2010International Journal of Agricultural and Biological Engineering2010,3,3:2

12Inter-ethnic marriages and severity of coronary artery disease:A multicenter study of Arabian Gulf States显示文摘AIM To assess the association of inter-ethnic vs intra-ethnic marriage with severity of coronary artery disease(CAD) in men undergoing angiography.METHODS We conducted a prospective multicenter,multi-ethnic,cross sectional observational study at five hospitals in Saudi Arabia and the United Arab Emirates,in which we used logistic regression analysis with and without adjustment for baseline differences. RESULTS Data were collected for 1068 enrolled patients undergoing coronary angiography for clinical indications during the period of April 1^(st),2013 to March 30^(th),2014. Ethnicities of spouses were available only for male patients. Of those enrolled,687 were married men and constituted the cohort for the present analysis. Intra-ethnic marriages were reported in 70% and inter-ethnic marriages in 30%. After adjusting for baseline differences,interethnic marriage was associated with lower odds of having significant CAD [adjusted odds ratio 0.52(95%CI:0.33,0.81)] or multi-vessel disease(MVD) [adjusted odds ratio 0.57(95%CI:0.37,0.86)]. The adjusted association with left main disease showed a similar trend,but was not statistically significant [adjusted odds ratio 0.74(95%CI:0.41,1.32)]. The association between interethnic marriage and the presence of significant CAD and MVD was not modified by number of concurrent wives(P interaction > 0.05 for both).CONCLUSION Among married men undergoing coronary angiography,inter-ethnic,as compared to intra-ethnic,marriage is associated with lower odds of significant CAD and MVD.Amin Daoulah Salem Al-kaabi Amir Lotfi Mushabab Al-Murayeh S Ali Nasseri Waleed Ahmed Salah N Al-Otaibi Mohamed N Alama Osama E Elkhateeb Amy J Plotkin Majed M Malak Khalid Alshali Mohamed Hamzi Saleh Al Khunein Mohammed Abufayyah Alawi A Alsheikh-Ali 2017World Journal of Cardiology2017,9,4:2
