1长期保护性耕种方式对农田表层土壤性质的影响显示文摘研究了不同耕种方式对澳大利亚同一地区3种土壤表层(0-5cm)理化性质的作用,以揭示保护性耕作对土壤质量恢复的影响。结果表明:免耕穴播/保留残茬(DD/SR)、多年生人工草地(PP)和自然草地(NP)表层土壤的〉2mm水稳性团聚体含量、全氮、有机碳含量、田间持水量均显著高于其相应对照传统耕作/秸秆焚烧(CC/SB)、人工草地/作物轮作(PPC)和耕作(CT)的;土壤全氮含量、田间持水量分别与有机碳含量之间有极显著的正相关关系(r=0.994**,r=0.996**,n=6),而受土壤质地等因素的影响较小;在同一类型的土壤上,土壤有机碳含量与水稳定性团聚体含量之间存在显著的相关性;在不同试验区,耕作措施对表层土壤容重和孑L隙分布的影响存在较大差异;秸秆焚烧和施用石膏对表层土壤的pH及交换性阳离子含量有较大的影响。研究表明长期保护性耕作、草田轮作或多年生草地有利于提高表层土壤有机碳含量和结构稳定性,从而改善土壤的供肥供水能力。张国盛 K Y Chan G D Li D P Heenan 2008生态学报2008,28,6:45
2延胡索酸水合酶缺陷型肾细胞癌32例临床病理和分子分析显示文摘延胡索酸水合酶缺陷型肾细胞癌属于罕见的、新近发现的与遗传性平滑肌瘤病和肾细胞癌综合征相关的肿瘤实体。延胡索酸水合酶缺陷型肾细胞癌可表现出多种临床和病理学表现,但通常表现为局部进展和转移性疾病,预后较差。作者通过延胡索酸水合酶免疫组化和(或)延胡索酸水合酶突变分析确定32例延胡索酸水合酶缺陷型肾细胞癌,并对其临床和病理特征进行回顾性分析。Lau H D Chan E Fan A C 魏建国(摘译) 方三高(审校) 2020临床与实验病理学杂志2020,36,3:19
3Polymethylmethacrylate bone cements and additives: A review of the literature显示文摘Polymethylmethacrylate(PMMA) bone cement technology has progressed from industrial Plexiglass administration in the 1950 s to the recent advent of nanoparticle additives. Additives have been trialed to address problems with modern bone cements such as the loosening of prosthesis, high post-operative infection rates, and inflammatory reduction in interface integrity. This review aims to assess current additives used in PMMA bone cements and offer an insight regarding future directions for this biomaterial. Low index(< 15%) vitamin E and low index(< 5 g) antibiotic impregnated additives significantly address infection and inflammatory problems, with only modest reductions in mechanical strength. Chitosan(15% w/w PMMA) and silver(1% w/w PMMA) nanoparticles have strong antibacterial activity with no significant reduction in mechanical strength. Future work on PMMA bone cements should focus on trialing combinations of these additives as this may enhance favourable properties.Manit Arora Edward KS Chan Sunil Gupta Ashish D Diwan 2013World Journal of Orthopedics2013,4,2:10
