| 1 | Novel technique of penetrating keratoplasty in high-risk grafts with significant corneal neovascularization显示文摘Dear Editor,We write to introduce a novel technique of penetrating keratoplasty(PK)with lower risk of graft rejection in high-risk grafts.Corneal transplantation may be required in a variety of conditions such as keratoconus,pseudophakic bullous keratopathy(PBK),and corneal scars or dystrophies[1]. | Mohammad Soleimani Nader Mohammadi Mansoor Shahriari Morteza Karimi Ahmed Alshaheeb Atefeh Khalili Mohammad Hossein Zamani Kasra Cheraqpour | 2022 | International Journal of Ophthalmology(English edition)2022，15，9： | 1 |
| 2 | Spatio-temporal suspended sediment fingerprinting under different land management practices显示文摘Understanding spatio-temporal suspended sediment dynamics is more important in large watersheds due to the decisive role of local source apportionment in sediment transport and yield.The Talar River with a large mountainous watershed in northern Iran,which plays a vital role in water supply for agriculture and drinking,recently has faced quality degradation.The current study explores the relative contribution of suspended sediment sources using geochemical tracers and fingerprinting techniques in high and low flow periods along this river.Soil samples were collected from four major land uses including rangeland,forest,rainfed agriculture,and irrigated agriculture,as well as riverbanks and riparian zones along the main river.Furthermore,suspended sediment was sampled at four sampling points along the main river in two seasons.Land use apportionment in suspended sediment yield was calculated using an unmixing model included in a newly developed package(Finger Pro)in high flow and low flow,separately.The fingerprinting results showed a highly spatio-temporal dynamic for sediment source contribution along the main river in high and low flow periods.Natural land uses(forest and rangeland)in upstream reaches and agricultural land uses and riverbank sources in downstream reaches showed higher contributions to suspended sediment yield.The mean contribution of various land uses for both high and low flow periods indicated substantial contributions from forest(34%-41%)and riverbanks(31%-33%).The significant difference in sediment geochemical properties for the two flow seasons highlights the important role of the prevailing climatic-hydrologic condition on river sediment.Moreover,this issue indicates that sediment source contributions and transfer mechanisms are highly dynamic in Talar River watershed.The current study outcomes provide essential knowledge to create a robust strategy for mitigation of river sediment pollution. | Maziar Mohammadi Abdulvahed Khaledi Darvishan Nader Bahramifar Seyed Jalil Alavi | 2023 | International Journal of Sediment Research2023，38，4： | 1 |

| 4 | SBA-15锚定Cu(Ⅱ)-DiAmSar配合物催化剂上无溶剂高效合成吡啶并吡嗪和喹喔啉衍生物(英文)显示文摘A catalytic system comprising mesoporous silica functionalized with Cu(II)-DiAmSar was synthesized. This was demonstrated as an efficient heterogeneous catalyst for the synthesis of biologically useful pyridopyrazine and quinoxaline heterocycles under solvent-free conditions. X-ray diffraction, transmission electron microscopy, N2 adsorption-desorption, Fourtier transformation infrared spectroscopy, and thermogravimetric analysis were used to characterize the catalyst and investigate the texture of SBA-15 during the grafting process. | Marzieh Mohammadi Ghasem Rezanejade Bardajee Nader Noroozi Pesyan | 2015 | 催化学报2015，36，8： | 0 |
| 5 | Global prevalence of drug-resistant tuberculosis: a systematic review and meta-analysis显示文摘Background Tuberculosis is a bacterial infectious disease,which affects different parts of a human body,mainly lungs and can lead to the patient’s death.The aim of this study is to investigate the global prevalence of drug-resistant tuberculosis using a systematic review and meta-analysis.Methods In this study,the PubMed,Scopus,Web of Science,Embase,ScienceDirect and Google Scholar repositories were systematically searched to find studies reporting the global prevalence of drug-resistant tuberculosis.The search did not entail a lower time limit,and articles published up until August 2022 were considered.Random effects model was used to perform the analysis.The heterogeneity of the studies was examined with the I^(2) test.Data analysis was conducted within the Comprehensive Meta-Analysis software.Results In the review of 148 studies with a sample size of 318,430 people,the I^(2) index showed high heterogeneity(I^(2)=99.6),and accordingly random effects method was used to analyze the results.Publication bias was also examined using the Begg and Mazumdar correlation test which indicated the existence of publication bias in the studies(P=0.008).According to our meta-analysis,the global pooled prevalence of multi-drug resistant TB is 11.6%(95%CI:9.1–14.5%).Conclusions The global prevalence of drug-resistant tuberculosis was found to be very high,thus health authorities should consider ways to control and manage the disease to prevent a wider spread of tuberculosis and potentially subsequent deaths. | Nader Salari Amir Hossein Kanjoori Amin Hosseinian-Far Razie Hasheminezhad Kamran Mansouri Masoud Mohammadi | 2023 | Infectious Diseases of Poverty2023，12，3： | 0 |
