1温室番茄同步叶片修剪对干物质生产和分配影响的模拟分析显示文摘【目的】优化干物质在营养生长库与生殖生长库之间的分配,提高温室番茄栽培的效益。【方法】通过TOMSIM模拟与温室试验研究同步叶片修剪对温室番茄品种Capita干物质生产与分配的影响。【结果】TOMSIM模拟试验与温室试验结果相当吻合。与对照相比,模拟试验与温室试验中叶修剪处理的平均LAI分别从2.9显著降至1.9与2.4,单位面积植株总干重分别显著降低12.2%与10.5%,果实累计干物质分配率分别从57.1%与56.6%显著提高到61.5%与60.7%,使得单位面积果实干重分别只降低5.9%与4.2%;在叶修剪&高密度处理中,平均LAI分别增至2.9与3.6,单位面积植株总干重增加4.0%与15.2%,果实累计干物质分配率分别为61.1%与57.9%,使得单位面积果实干重分别增加9.9%与16.9%。【结论】温室番茄同步叶片修剪,一方面,显著降低LAI与单位面积植株总干重;另一方面,显著提高果实累积干物质分配率。增加植株密度能增加LAI,但对果实累计干物质分配率没有显著影响。同步叶片修剪加高密度能显著提高单位面积果实干重。肖深根 周朴华 Ep Heuvelink 刘志敏 2006中国农业科学2006,39,10:15
2Non-parasitic splenic cysts: A report of three cases显示文摘Primary splenic cyst is a relatively rare disease, and the majority of cases are classified as epithelial cysts. Three cases with nonparasitic splenic cysts are presented: two epithelial and one pseudocyst. All cases had an atypical symptomatology, consisted mainly of fullness in the left upper abdomen and a palpable mass. Preoperative diagnosis was established with ultrasonography and computerized tomography. Two cases with large cysts located in the splenic hilum were treated with open complete splenectomy. The most recent case, a pseudocyst, was managed laparoscopically with partial cystectomy. All cases did not have any problems or recurrence during follow-up. Laparoscopic partial cystectomy is an acceptable procedure for the treatment of splenic cysts, because it cures the disease preserving the splenic tissue. Complete splenectomy is reserved for cases in which cyst excision cannot be done otherwise.Macheras A Misiakos EP Liakakos T Mpistarakis D Fotiadis C Karatzas G 2005World Journal of Gastroenterology2005,11,43:11
3Colonic duplication in adults: Report of two cases presenting with rectal bleeding显示文摘Gastrointestinal duplication is an uncommon congenital abnormality in two-thirds of cases manifesting before the age of 2 years. Ileal duplication is common while colonic duplication, either cystic or tubular, is a rather unusual clinical entity that remains asymptomatic and undiagnosed in most cases. Mostly occurring in pediatric patients,colonic duplication is encountered in adults only in a few cases. This study reports two cases of colonic duplication in adults. Both cases presented with rectal bleeding on admission. The study was focused on clinical, imaging,histological, and therapeutical aspects of the presenting cases. Gastrografin enema established the diagnosis in both cases. The cystic structure and the adjacent part of the colon were excised en-block. The study implies that colonic duplication, though uncommon, should be included in the differential diagnosis of rectal bleeding.C Fotiadis M Genetzakis I Papandreou EP Misiakos E Agapitos GC Zografos 2005World Journal of Gastroenterology2005,11,32:7

5Evaluation of oxidative stress levels in obesity and diabetes by the free oxygen radical test and free oxygen radical defence assays and correlations with anthropometric and laboratory parameters显示文摘BACKGROUND Obesity and diabetes are associated with high levels of oxidative stress.In Romanian patients with obesity and(or)diabetes,this association has not been sufficiently explored.AIM To evaluate oxidative stress in obese and(or)diabetic subjects and to investigate the possible correlations between oxidative stress and anthropometric/biochemical parameters.METHODS Oxidative stress was evaluated from a single drop of capillary blood.Reactive oxygen species(ROS)were evaluated using the free oxygen radical test(FORT).The free oxygen radical defence(FORD)assay was used to measure antioxidant levels.RESULTS FORT levels were higher in obese subjects(3.04±0.36 mmol/L H2O2)vs controls(2.03±0.14 mmol/L H2O2)(P<0.0001).FORD levels were lower in obese subjects(1.27±0.13 mmol/L Trolox)vs controls(1.87±1.20 mmol/L Trolox)(P=0.0072).Obese diabetic subjects had higher FORT values(3.16±0.39 mmol/L H2O2)vs non-diabetic counterparts(2.99±0.33 mmol/L H2O2)(P=0.0233).In obese subjects,FORT values correlated positively with body mass index(BMI)(r=0.48,P=0.0000),waist circumference(WC)(r=0.31,P=0.0018),fasting plasma glucose(FPG)(r=0.31,P=0.0017),total cholesterol(TC)(r=0.27,P=0.0068)and uric acid(r=0.36,P=0.0001).FORD values correlated negatively with BMI(r=-0.43,P=0.00001),WC(r=-0.28,P=0.0049),FPG(r=-0.25,P=0.0130),TC(r=-0.23,P=0.0198)and uric acid(r=-0.35,P=0.0002).In obese diabetic subjects,FORT values correlated positively with BMI(r=0.49,P=0.0034)and TC(r=0.54,P=0.0217).FORD values were negatively associated with BMI(r=-0.54,P=0.0217)and TC(r=-0.58,P=0.0121).CONCLUSION Oxidative stress levels,as measured by the FORT and FORD assays,were higher in obese subjects vs controls.ROS levels were elevated in diabetic obese patients vs obese non-diabetic patients and controls.Mihnea-Alexandru Găman Mirela Elena Epîngeac Camelia Cristina Diaconu Amelia Maria Găman 2020World Journal of Diabetes2020,11,5:3

7气相传输SHS合成Ti_5Si_3的过程参数与产物结构的研究显示文摘气相传输自蔓延高温合成技术(self-propagatinghigh-temperaturesynthesis,SHS)是通过引入气相传输助剂(gastransportagent,GTA)来改变SHS过程的一种方法。GTA的引入对SHS过程参数、产物结构等产生显著的影响。本研究采用气相传输自蔓延高温合成法制备了Ti5Si3,并着重研究了GTA对热爆和自蔓延燃烧过程参数的影响,运用XRD和SEM对产物的组成与微观结构进行了分析。王皓 傅正义 袁润章 Kostogorov EP 1997硅酸盐学报1997,25,5:2
8基于库调节的温室番茄干物质生产与分配显示文摘研究了库调节对温室番茄(LycopersiconesculentumMill.)品种“Capita”干物质生产与分配的影响。结果表明,温室番茄干物质生产主要由LAI决定而与果穗座果数无直接关联,在果穗修剪为恒定的6(或3)个果实时,叶片修剪能显著降低LAI,从而导致植株总干物质生产的显著降低。增加果穗座果数与叶片修剪均能显著提高植株果实的累积干物质分配率。增加植株密度并不能提高植株果实干物质分配率,但可以提高LAI。高密度处理中单位面积植株果实干重的增加主要是由于总的干物质生产增加的缘故。肖深根 周朴华 Ep Heuvelink 刘志敏 2005热带作物学报2005,26,4:2

10同步叶片修剪对温室番茄产量与植株发育的影响显示文摘研究了同步叶片修剪对温室番茄品种“Capita”产量与植株发育的影响。结果表明,在修剪每穗果实为6时,同步叶片修剪显著地将叶面积指数(leafareaindex,LAI)从2.9m2/m2降至2.4m2/m2,从而导致番茄植株总产量显著降低5.2%,但果实产量并未降低。当植株密度从2.5株/m2增加到3.8株/m2时,LAI显著地从2.4m2/m2增加到3.6m2/m2,虽然单位植株的总产量与果实产量分别降低了13.0%与9.0%,但是单位面积植株的总产量与果实产量反而分别增加了32.3%与38.4%。同步叶片修剪与植株密度并不影响植株的发育,对植株高度也没有显著影响。肖深根 周朴华 Ep Heuvelink 2005中国农学通报2005,21,7:2

12基于源-库互反馈的温室青椒坐果时空动态模拟显示文摘植株各节位果实的生长将直接影响无限生长型的温室青椒的产量。植株生长过程中各节位的果实同时竞争同化物的分配,源-库供应关系发生变化反馈影响各节位坐果的能力,因此明确源-库动态对坐果的反馈机理对理解产量形成机制具有重要意义。根据温室青椒每个节位器官生物量-形态的实测数据,反求了描述植株各个器官生长过程的参数值,构建了'源-库'互反馈关系的青椒生长模型,量化描述了植株生长过程中源-库动态变化与坐果的时空关系。当源-库比阈值为1.0时,最能反映植株的坐果时空变化规律,此时果实、叶片、叶柄和节间的模拟值与实测值的误差RMSE值分别为15.3、7.4、4.8、5.7g。模型通过源-库动态与坐果空间分布的虚拟模拟进一步解释了果实生长与源-库动态的交互作用效果。马韫韬 朱晋宇 胡包钢 Heuvelink Ep de Reflye Philippe 2010生态学报2010,30,24:2
