| 1 | 加氧灌溉对菠萝根区土壤呼吸和生理特性的影响显示文摘通过大田试验,研究了加氧灌溉对菠萝根区土壤呼吸作用、生理特性、生物量积累、果实产量、品质和水分利用效率的影响.采用Mazeei(空气注射器)给地下灌溉系统加入空气,设计了加氧和不加氧灌溉2种处理方式,7次重复.设计滴头埋深10 cm.研究表明,与对照相比,菠萝根区30 cm以内土壤水分质量分数和CO2质量分数没有明显差异,但是加氧灌溉使得土壤呼吸增加了100%;菠萝的果实鲜重、生物量鲜重、干物质重和收获指数明显增大,差异有统计学意义(p≤0.05);加氧灌溉提高了菠萝的水分生产率,与对照相比增加了17.2%;同时,加氧灌溉明显改善了菠萝单果尺寸和重量,使得单果重量增加了17.3%,田间产量增加了4.3%,增加了果实的糖质量分数,减少了果实的透明物.研究结果为加氧灌溉技术的推广应用提供了理论依据. | 陈新明 Jay Dhungel Surya Bhattarai Manouchehr Tobrabi Dayid J Midmore | 2010 | 排灌机械工程学报2010,28,6: | 43 |
| 2 | Impact of oxygation on soil respiration, yield and water use efficiency of three crop species显示文摘Oxygation refers to irrigation of crops with aerated water,through air injection using the venturi principle or the supply of hydrogen peroxide in the root zone,both using subsurface drip irrigation(SDI)system.Oxygation improves water use efficiency(WUE),producing more yield and,and therefore,optimizes the use of drip and SDI.But the efficiency of oxygation is quite possibly dependent on a number of factors.The primary objective of this study was,therefore,to quantify the effects of oxygation,emitter depths and soil type on crop root zone oxygen content,soil respiration,plant physiological response,biomass yield,quality and WUE of three crop species.Methods This study investigated the potential of oxygation to enhance soil respiration,plant growth,yield and water use efficiencies(WUE)of cotton and wheat in experiments in enclosed heavy-duty concrete troughs(tubs)and pineapple and cotton in field experiments.Experimental treatments in tubs for wheat included comparisons between two soil types(vertisol and ferrosol)and superimposed were two oxygation methods(Mazzei air injector and Seair Diffusion System)compared to a control,and for cotton,emitters at two depths using Mazzei air injectors were compared to a control.The field experiments compared Mazzei air injectors and a control for cotton in Emerald and pineapple in Yeppoon,both in central Queensland,Australia.Important findings In all experiments,soil oxygen content and soil respiration markedly increased in response to the oxygation treatments.The O2 concentration in the crop root zone increased by 2.4–32.6%,for oxygation compared to control at the same depth.The soil respiration increased by 42–100%.The number of wheat ears,leaf dry weight and total dry matter were significantly greater in Mazzei and Seair oxygation compared to the control.Fresh biomass of wheat increased by 11 and 8%,and dry weight of wheat increased by 8 and 3%in Mazzei and Seair oxygation treatments compared to the control,respectively.Likewise,the irrigation water use efficiency increased with oxygation compared to the control in wheat.The yield,WUE and number of other physiological parameters in wheat were enhanced in vertisol compared to ferrosol.The seed cotton yield in the tub experiment increased with oxygation by 14%,and significant differences for fresh biomass,dry matter and yield were also noted between oxygation and the control in the field.Lint yield and WUE both increased by 7%using Mazzei in the cotton field trial during 2008–09.There were significant effects of oxygation on pineapple fresh biomass,and dry matter weight,industry yield and a number of quality parameters were significantly improved.The total fruit yield and marketable increased by 17 and 4%and marketable WUE increased by 3%using Mazzei.Our data suggest that the benefits of oxygation are notable not only for dicotyledonous cotton but also for monocotyledonous wheat and pineapple representing different rooting morphologies and CO_(2) fixation pathways. | Xinming Chen Jay Dhungel Surya P.Bhattarai Manouchehr Torabi Lance Pendergast David J.Midmore | 2011 | Journal of Plant Ecology2011,4,4: | 46 |
| 3 | 弱视儿童的临床概况和遮盖治疗结果显示文摘目的:研究弱视的临床表现,以及对弱视患者进行遮盖治疗的效果。方法:纵向研究。收集2015-04/2016-04 Dhulikhel医院眼科1092例患者数据。对检出的弱视60例患儿的视力、主诉、年龄、屈光状态、双眼屈光度和注视方式进行评估。并对检出的弱视患儿进行遮盖治疗。结果:在研究期间接受检查的1092例儿童中,60例(5.49%)为弱视患者,其中,女性35例(58.30%),男性25例(41.70%),平均年龄为8.87±3.29岁。在43.3%(n=26)的弱视儿童中,经线性弱视是最常见的亚型,其次是远视性屈光参差性弱视(20%,n=12)。最常见的屈光不正是散光,占58.30%,其次是远视(22.50%)和近视(7.50%)。配戴眼镜联合遮盖治疗和主动视觉训练的依从性为73.30%(n=44)。3mo后不同治疗策略对弱视眼视力有显著改善(P=0.002)。结论:在尼泊尔等发展中国家,弱视发病率和相关的视力损害仍然是一个公共卫生问题。意识的缺乏,社区或学龄前儿童视力筛查的缺乏,会导致儿童较晚出现症状,并最终导致明显的视力损害。通过筛选就诊地点、及时转诊和适当的干预措施,这种状况可得到改善。 | Raju Kaiti Pabita Dhungel Asik Pradhan Monica Chaudhry | 2020 | 国际眼科杂志2020,20,11: | 7 |
| 4 | Murine hepatocellular carcinoma derived stem cells reveal epithelial-to-mesenchymal plasticity显示文摘AIM To establish a model to enrich and characterize stemlike cells from murine normal liver and hepatocellular carcinoma(HCC) cell lines and to further investigate stem-like cell association with epithelial-to-mesenchymal transition(EMT).METHODS In this study,we utilized a stem cell conditioned serumfree medium to enrich stem-like cells from mouse HCC and normal liver cell lines,Hepa 1-6 and AML12,respectively.We isolated the 3-dimensional spheres and assessed their stemness characteristics by evaluating theRNA levels of stemness genes and a cell surface stem cell marker by quantitative reverse transcriptase-PCR(q RTPCR).Next,we examined the relationship between stem cells and EMT using q RT-PCR.RESULTS Three-dimensional spheres were enriched by culturing murine HCC and normal hepatocyte cell lines in stem cell conditioned serum-free medium supplemented with epidermal growth factor,basic fibroblast growth factor and heparin sulfate.The 3-dimensional spheres had enhanced stemness markers such as Klf4 and Bmi1 and hepatic cancer stem cell(CSC) marker Cd44 compared to parental cells grown as adherent cultures.We report that epithelial markers E-cadherin and ZO-1 were downregulated,while mesenchymal markers Vimentin and Fibronectin were upregulated in 3-dimensional spheres.The 3-dimensional spheres also exhibited changes in expression of Snai,Zeb and Twist family of EMT transcription factors.CONCLUSION Our novel method successfully enriched stem-like cells which possessed an EMT phenotype.The isolation and characterization of murine hepatic CSCs could establish a precise target for the development of more effective therapies for HCC. | Aparna Jayachandran Ritu Shrestha Bijay Dhungel I-Tao Huang Marianna Yumi Kawashima Vasconcelos Brian J Morrison Charmaine A Ramlogan-Steel Jason C Steel | 2017 | World Journal of Stem Cells2017,9,9: | 4 |
