| 1 | 赤霉素及噻苯隆处理对‘夏黑’葡萄果实品质的影响显示文摘松散的果穗有利于鲜食葡萄果粒的膨大和品质形成,还可减少果粒相互挤压破裂。但人工疏花和疏粒费时费力,成本高。为此,以4年生‘夏黑’葡萄为试验材料,调查赤霉酸(GA3)拉长穗轴效果,并探讨GA3和噻苯隆(TDZ)的保果和膨大处理对果实品质的影响。结果表明,在盛花前14 d用10~15 mg/L GA3溶液浸泡花穗可有效拉长花穗,满花时及花后10 d分别用25 mg/L GA3及25 mg/L GA3+3~5 mg/L TDZ溶液浸蘸拉长后的果穗,可提高坐果率和促进果粒膨大,增加粒质量、纵横径效果显著,但对果汁可溶性固形物积累有不良影响。 | 赵茂香 郑伟尉 HAFIZ Umer Javed | 2021 | 中外葡萄与葡萄酒2021，，1： | 10 |
| 2 | 籽瓜、黏籽和普通西瓜的果实代谢组比较显示文摘【目的】西瓜是一种广受欢迎的夏季水果,籽用西瓜(籽瓜)、黏籽西瓜和普通西瓜是3种重要的栽培类型,但对其果实中代谢物全面鉴定的研究很少,比较这3种西瓜果实的代谢组学差异,为明确驯化改良对不同类型西瓜代谢组的影响提供新见解。【方法】试验以5份籽用西瓜、5份黏籽西瓜和6份普通西瓜为材料,对成熟期果肉进行广泛靶向代谢组学检测,采用SIMCA-P、MetaboAnalyst 5.0、Origin等软件对代谢组数据进行分析。【结果】LC-MS分析共检测到323种代谢物,包括51种氨基酸及其衍生物、21种核苷酸及其衍生物、14种碳水化合物、32种有机酸、52种脂质、36种类黄酮、32种羟基肉桂酰衍生物等。PCA和聚类分析显示,籽用西瓜和黏籽西瓜的代谢组学轮廓差异较小,籽用西瓜的代谢组轮廓介于黏籽西瓜和普通西瓜之间。对分类贡献率较大的代谢物是蔗糖、柠檬酸、L-谷氨酸、L-苏氨酸、葫芦素类、香草酸糖苷异构体、脂质类等。聚类热图分析显示黏籽西瓜中特有的代谢物是葫芦素及其衍生物等,籽用西瓜中的绿原酸、LysoPE脂质类等化合物含量较高,普通西瓜中的糖类、精氨酸、阿魏酸及C18-2和C18-3不饱和脂肪酸等物质含量较高。比较分析共鉴定出156种差异代谢物,籽用西瓜与黏籽西瓜的主要差异代谢物有对香豆醛、阿魏酸、肉桂酸、蔗糖、葫芦素D O-葡萄糖苷、葫芦素E异构体、牡荆素、松柏醇等。籽用西瓜与普通西瓜的主要差异代谢物有脂质类、类黄酮类、有机酸类和糖类等。随着作物进化的程度增加,营养类代谢物质含量增加,抗性相关的代谢物质含量减少。【结论】籽用西瓜和黏籽西瓜的果实代谢组差异比籽用西瓜和普通西瓜的差异小,籽用西瓜的代谢轮廓介于黏籽西瓜和普通西瓜之间。除了表型和基因组差异外,代谢组差异也可以作为区分品种的重要依据。本研究首次在代谢组学水平比较了3种类型西瓜果实的差异,对深入理解西瓜种质资源,培育保健型西瓜新品种有重要的指导意义。 | 袁平丽 何楠 赵胜杰 路绪强 朱红菊 刁卫楠 龚成胜 MUHAMMAD Jawad Umer 刘文革 | 2021 | 中国农业科学2021，54，19： | 6 |
| 3 | An attending physician float shift for the improvement of physician productivity in a crowded emergency department显示文摘BACKGROUND:Patients backlogged in the emergency department(ED) waiting for an inpatient bed(boarders) continue to require the attention of ED physicians,exacerbating crowding in the ED.To address this problem,we added a 'float shift' to our winter schedule solely to care for boarders.We sought to quantify the effect of this float shift,hypothesizing greater physician productivity.METHODS:We performed a retrospective observational study in our community hospital ED,measuring the number of new patients seen in each 10-hour shift in the presence or absence of a float shift physician.We calculated the number of new patients seen per shift for each of the 7 daily shifts,during February(float shift scheduled) and May(float shift unscheduled) of 2008.We then compared the mean number of patients seen per shift in February with May.RESULTS:Total monthly patient volume was 6 656 for February and 6 775 for May,with the mean daily census being 230 and 219 patients,respectively.The number of new patients seen during each shift was greater in February than in May,with a mean increase of 1.1 patients per shift(with the float shift).Surveying participants about intervention effectiveness showed 92%of residents,but only 65%of attending physicians,in favor of maintaining the float shift.CONCLUSION:The presence of a 'float shift' physician caring only for boarding patients allows other physicians to maintain and even increase their productivity in our ED,despite the presence of longer throughput times and increased time on diversion. | Muhammad Umer Nasim Chintan Mistry Robert Harwood Erik Kulstad Laura Tommaso | 2013 | World Journal of Emergency Medicine2013，4，1： | 6 |

| 5 | Identification of key gene networks controlling organic acid and sugar metabolism during watermelon fruit development by integrating metabolic phenotypes and gene expression profiles显示文摘The organoleptic qualities of watermelon fruit are defined by the sugar and organic acid contents,which undergo considerable variations during development and maturation.The molecular mechanisms underlying these variations remain unclear.In this study,we used transcriptome profiles to investigate the coexpression patterns of gene networks associated with sugar and organic acid metabolism.We identified 3 gene networks/modules containing 2443 genes highly correlated with sugars and organic acids.Within these modules,based on intramodular significance and Reverse Transcription Quantitative polymerase chain reaction(RT-qPCR),we identified 7 genes involved in the metabolism of sugars and organic acids.Among these genes,Cla97C01G000640,Cla97C05G087120 and Cla97C01G018840(r^(2)=0.83 with glucose content)were identified as sugar transporters(SWEET,EDR6 and STP)and Cla97C03G064990(r^(2)=0.92 with sucrose content)was identified as a sucrose synthase from information available for other crops.Similarly,Cla97C07G128420,Cla97C03G068240 and Cla97C01G008870,having strong correlations with malic(r^(2)=0.75)and citric acid(r^(2)=0.85),were annotated as malate and citrate transporters(ALMT7,CS,and ICDH).The expression profiles of these 7 genes in diverse watermelon genotypes revealed consistent patterns of expression variation in various types of watermelon.These findings add significantly to our existing knowledge of sugar and organic acid metabolism in watermelon. | Muhammad Jawad Umer Luqman Bin Safdar Haileslassie Gebremeskel Shengjie Zhao Pingli Yuan Hongju Zhu M.O.Kaseb Muhammad Anees Xuqiang Lu Nan He Chengsheng Gong Wenge Liu | 2020 | Horticulture Research2020，7，1： | 4 |
| 6 | Mechanical strength of wheat grain varieties influenced by moisture content and loading rate显示文摘Mechanical shear resistance of wheat grain is a significant concern for the designers and researchers related to the design of threshing,handling and processing machinery of the field crops.The grain mechanical properties directly affect the machine geometry and its operational parameters.The present study was carried out to determine the shear resistance of five wheat varieties(Locally names;TD-02,Sindhu-1105,Benazir,China and SKD-118)influenced by moisture content(16.7%,18.7%and 19.5%)and loading rate(3 mm/s,6 mm/s and 9 mm/s).However,some physio-dimensional properties(length,width,thickness,slenderness ratio,surface area and sphericity)were obtained at different moisture contents.The results showed that the shear resistance reduced by increasing the moisture content and loading rate.The average shear resistance decreased from 10.45 N to 3.74 N for 3-9 mm/s loading rate at moisture content of 16.7%to 19.5%.Thus,the maximum correlation(r=0.905)of shear resistance obtained at 16.7%,whereas minimum correlation(r=0.692)obtained at 19.5%.The shear resistance of wheat grain was highly significant(p<0.05)at 9 mm/s for 19.5%.Shear resistance decreased with an increase in the moisture content in the grain whereas deformation is increasing with the increase of moisture content.However,the maximum bulk density of wheat grain obtained at 19.5%for SKD-118,while the minimum obtained at 16.7%for TD-02.It is recommended that the design and modification of wheat grain processing equipment should be executed on the physio-mechanical properties of grain varieties. | Yaoming Li Farman Ali Chandio Zheng Ma Imran Ali Lakhiar Abdul Razaque Sahito Fiaz Ahmad Irshad Ali Mari Umer Farooq Muhammad Suleman | 2018 | International Journal of Agricultural and Biological Engineering2018，11，4： | 4 |

| 10 | Real-Time Safety Helmet Detection Using Yolov5 at Construction Sites显示文摘The construction industry has always remained the economic and social backbone of any country in the world where occupational health and safety(OHS)is of prime importance.Like in other developing countries,this industry pays very little,rather negligible attention to OHS practices in Pakistan,resulting in the occurrence of a wide variety of accidents,mishaps,and near-misses every year.One of the major causes of such mishaps is the non-wearing of safety helmets(hard hats)at construction sites where falling objects from a height are unavoid-able.In most cases,this leads to serious brain injuries in people present at the site in general and the workers in particular.It is one of the leading causes of human fatalities at construction sites.In the United States,the Occupational Safety and Health Administration(OSHA)requires construction companies through safety laws to ensure the use of well-defined personal protective equipment(PPE).It has long been a problem to ensure the use of PPE because round-the-clock human monitoring is not possible.However,such monitoring through technological aids or automated tools is very much possible.The present study describes a systema-tic strategy based on deep learning(DL)models built on the You-Only-Look-Once(YOLOV5)architecture that could be used for monitoring workers’hard hats in real-time.It can indicate whether a worker is wearing a hat or not.The proposed system usesfive different models of the YOLOV5,namely YOLOV5n,YOLOv5s,YOLOv5 m,YOLOv5l,and YOLOv5x for object detection with the support of PyTorch,involving 7063 images.The results of the study show that among the DL models,the YOLOV5x has a high performance of 95.8%in terms of the mAP,while the YOLOV5n has the fastest detection speed of 70.4 frames per second(FPS).The proposed model can be successfully used in practice to recognize the hard hat worn by a worker. | Kisaezehra Muhammad Umer Farooq Muhammad Aslam Bhutto Abdul Karim Kazi | 2023 | Intelligent Automation & Soft Computing2023，，4： | 2 |

| 12 | Hepatitis C virus prevalence and genotype distribution inPakistan:Comprehensive review of recent data显示文摘Hepatitis C virus(HCV) is endemic in Pakistan and its burden is expected to increase in coming decades owing mainly to widespread use of unsafe medical procedures. The prevalence of HCV in Pakistan has previously been reviewed. However, the literature search conducted here revealed that at least 86 relevant studies have been produced since the publication of these systematic reviews. A revised updated analysis was therefore needed in order to integrate the fresh data. A systematic review of data published between 2010 and 2015 showed that HCV seroprevalence among the general adult Pakistani population is 6.8%, while active HCV infection was found in approximately 6% of the population. Studies included in this review have also shown extremely high HCV prevalence in rural and underdeveloped peri-urban areas(up to 25%), highlighting the need for an increased focus on this previously neglected socioeconomic stratum of the population. While a 2.45% seroprevalence among blood donors demands immediate measures to curtail the risk of transfusion transmitted HCV, a very high prevalence in patients attending hospitals with various non-liver disease related complaints(up to 30%) suggests a rise in the incidence of nosocomial HCV spread. HCV genotype 3a continues to be the most prevalent subtype infecting people in Pakistan(61.3%). However, recent years have witnessed an increase in the frequency of subtype 2a in certain geographical sub-regions within Pakistan. In Khyber Pakhtunkhwa and Sindh provinces, 2a was the second most prevalent genotype(17.3% and 11.3% respectively). While the changing frequency distribution of various genotypes demands an increased emphasis on research for novel therapeutic regimens, evidence of high nosocomial transmission calls for immediate measures aimed at ensuring safe medical practices. | muhammad umer mazhar iqbal | 2016 | World Journal of Gastroenterology2016，22，4： | 2 |

| 16 | Hydrochemical characteristics and water quality assessment for drinking and agricultural purposes in District Jacobabad,Lower Indus Plain,Pakistan显示文摘Undeniably water is of utmost importance while considering basic necessities.This investigation emphasized on the hydrochemical evaluation and drinking water quality assessment in District Jacobabad located in lower Indus plain,Pakistan.Certainly world's largest irrigation system emerged from Indus Basin,which is underlain by well transmissive aquifer resulting in higher water table.Water supply schemes with their water sources from ground water and surface water provide piped water for drinking purpose to the community.Water samples were collected from all the forty eight supply schemes of which thirty two were found nonfunctional.Analytical parameters were compared with World Health Organization(WHO)and Pakistan Water Quality Standards but adversely substantial samples were found nonpotable.Alkalinity,bicarbonate and nitrate met the standard safe limits while values for EC,TDS,hardness,cations and anions exceeded the limits in numerous samples.SPSS and ArcGIS softwares were used for statistical analysis and spatial distribution of parameters.Hydrochemical facies were developed and suitability assessment of water resources was examined for agricultural use.The ground water type was classified as Na-HCO3 type with high salinity and it required treatment prior to irrigation.The proposed research exhibited the probable drinking water contamination sources and it demanded instant actions to further protect the valuable drinking water resources in District Jacobabad. | Asfandyar Shahab Shihua Qi Muhammad Zaheer Audil Rashid Muhammad Afnan Talib Umer Ashraf | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 2 |
| 17 | Integrated Mineral Analysis of sandstone and dolomite formations using different chelating agents during matrix acidizing显示文摘Mineral analysis plays a major role in the successful matrix acidizing as it shows the change in physiochemical changes in the formation due to the reaction with fluids injected.Mineralogy of the reservoir can be altered by injecting mineral acids during matrix acidizing.But various complications are connected during the application of these acids such as environmental hazards,corrosion of pipes and tubings,precipitation of fluosilicates and fast spending of acid.To mitigate these problems,chelating agents have been applied as an alternative by different researchers.In this study,three different chelating agents EDTA,GLDA and HEDTA were applied to stimulate sandstone and dolomite samples.The pH value of these chelates ranges from 1.7 to 3 and is measured before and after core flooding to observe physiochemical changes.Core flooding experiments under 180F temperature were performed at a constant flow rate of 1 ml/min on core samples having dimensions(3 inch1.5 inch).Porosity,permeability,Inductively Coupled Plasma(ICP),and TESCAN Integrated Mineral Analysis(TIMA)were employed to measure changes in formation properties such as morphology,topology and mineralogy.The reacted sample of acids was analyzed for sodium,potassium,calcium,aluminium,magnesium,and iron using the ICP technique to find the capability of these chelates to remove positive ions.HEDTA found to be effective in chelating iron,calcium and magnesium and it also removed some amount of aluminium ions from the sandstone samples.Permeability and porosity analysis concluded that HEDTA is more efficient in creating new big pore spaces.TIMA analysis confirms that HEDTA is effective in dissolving quartz and other positive ions while dissolved a large amount of calcium and sodium from the sandstone as compared to other chelates.TIMA analysis also concluded that HEDTA is effective in increasing porosity of sandstone formation while GLDA is effective in dolomites. | Mian Umer Shafiq Hisham Khaled Ben Mahmud Mohsen Ghasemi | 2019 | Petroleum2019，5，1： | 2 |
