1云南常见牛肝菌属真菌中汞含量及食用安全评价显示文摘汞(Hg)是危害人类健康的主要重金属元素之一,多数食用菌对Hg有很强的富集能力,测定食用菌中Hg含量,并对其进行食用安全性评价具有重要意义。采用冷原子吸收直接测汞仪系统测定85份云南常见牛肝菌属真菌菌盖、菌柄中总Hg含量;以同一牛肝菌子实体菌盖与菌柄总Hg含量比(Q(C/S))分析牛肝菌属真菌对Hg的富集特征;根据联合国粮农组织和世界卫生组织(FAO/WHO)现行每周Hg允许摄入量(provisional tolerable week—lyintake,PTWI)标准和中国GB2762—2012规定的食用菌中Hg限量标准评价样品的食用安全性。结果表明,菌盖和菌柄中总Hg含量分别在0.13—22.00、0.20~8.40mg·kg^-1DW,不同产地、种类及不同采集年份的样品中总Hg含量存在明显差异;同一牛肝菌菌盖、菌柄总Hg含量比(Q(C/S))在0.28~4.08,92%的样品Q((C/S))〉1,表明多数样品中菌盖对Hg的富集能力强于菌柄。根据GB2762-2012规定的食用菌及其制品中总Hg含量限量标准(≤0.1mg·kg^-1),发现所有测试样品的总Hg含量均超标;根据PTWI标准,假设成年人(60kg)每周食用300g新鲜牛肝菌,则多数样品Hg摄入量低于允许摄入量,无安全风险,而少数样品Hg摄入量高于允许摄入量,食用有一定的潜在风险。同时,牛肝菌总Hg含量与种类、产地、采集时间等因素密切相关,采食及安全评价需综合考虑这些因素。杨天伟 张霁 Jerzy FALANDYSZ Grazyna KRASIИSKA Martyna SABA 王元忠 刘鸿高 2015生态学杂志2015,34,12:12
2云南省野生牛肝菌总汞含量测定分析及健康风险评估显示文摘【目的】系统测定云南常见野生牛肝菌中总Hg含量,分析不同产地、种类及不同部位牛肝菌对Hg的富集规律和积累特征,评价野生牛肝菌的食用安全性,为野生食用菌产业的发展和食用安全评估提供数据依据。【方法】采用MA-2000直接测Hg仪—冷原子吸收光谱法测定牛肝菌菌盖、菌柄中总Hg含量,计算同一牛肝菌菌盖与菌柄总Hg含量比(QC/S),分析不同种类、部位牛肝菌中总Hg含量的差异和富集规律。根据中国《食品安全国家标准食品中污染物限量》(GB 2762—2012)规定的食用菌中Hg限量标准及联合国粮农组织和世界卫生组织(FAO/WHO)规定的每周Hg允许摄入量(provisional tolerable weekly intake,PTWI)现行标准,评价云南野生牛肝菌的食用安全性。【结果】同一子实体菌盖与菌柄的比值(QC/S)在0.3~8.8之间,95%牛肝菌样品菌盖、菌柄总Hg含量比(QC/S)≥1,表明多数牛肝菌菌盖对Hg的富集能力强于菌柄。本研究中多数野生牛肝菌菌盖、菌柄总Hg含量超过GB 2762—2012规定的食用菌中Hg含量限量标准(≤0.1 mg/kg);根据PTWI标准,假设成年人(60 kg)每周食用300 g新鲜牛肝菌,则多数样品Hg摄入量低于允许摄入量,无安全风险,而2013年采自玉溪大营街的美味牛肝菌,2012年采自楚雄永仁县的铜色牛肝菌及2014年采自玉溪新平的绒柄牛肝菌等少数样品Hg摄入量高于该标准。【结论】不同产地、种类牛肝菌菌盖、菌柄中总Hg含量存在明显差异,有少数牛肝菌总Hg含量超过相关标准,食用具有一定的潜在风险。李杰庆 杨天伟 张霁 Jerzy FALANDYSZ Grazyna KRASINSKA Martyna SABA 王元忠 刘鸿高 2017云南农业大学学报(自然科学版)2017,32,3:4
3New insight into the role of the complement in the most common types of retinopathy-current literature review显示文摘Pathological neovascularisation, which is a critical component of diseases such as age-related macular degeneration(AMD), diabetic retinopathy(DR) and retinopathy of prematurity(ROP), is a frequent cause of compromised vision or blindness. Researchers continuously investigate the role of the complement system in the pathogenesis of retinopathy. Studies have confirmed the role of factors H and I in the development of AMD, and factors H and B in the development of DR. Other components, such as C2, C3, and C5, have also been considered. However, findings on the involvement of the complement system in the pathogenesis of ROP are still inconclusive. This paper presents a review of the current literature data, pointing to the novel results and achievements from research into the role of complement components in the development of retinopathy. There is still a need to continue research in new directions, and to gather more detailed information about this problem which will be useful in the treatment of these diseases.Martyna Chrzanowska Anna Modrzejewska Monika Modrzejewska 2018International Journal of Ophthalmology(English edition)2018,11,11:3
4云南野生牛肝菌生长土壤汞含量分布特征显示文摘人为因素释放的Hg对环境造成严重污染,研究云南野生菌主产区土壤Hg含量对于环境保护和食品安全具有重要意义。该研究收集云南10个地州的57份牛肝菌生长土壤(0~10 cm)样本,并采用冷蒸气原子吸收光谱法对其Hg含量进行测定。结果表明,不同地区样本Hg含量范围(mg/kg,以干重计算)分别为:0.036~3.2(玉溪)、0.089~1.2(楚雄)、0.075~2.5(大理)、0.22~1.1(昆明)、0.075~0.34(曲靖)、0.36~0.98(红河)、0.12~1.3(迪庆)、0.30~0.83(保山)、0.047~0.53(普洱)、1.2(文山)。采自玉溪的土壤样本中Hg含量变化范围最大。除1份玉溪样本外,其他样本Hg含量均高于中国土壤背景值(0.038 mg/kg),可能对野生菌中Hg含量提高有一定影响。未来研究应着重考虑土壤Hg与牛肝菌Hg之间的关系。张霁 Martyna Saba Anna Wiejak Jerzy Falandysz 王元忠 2016环境科学与技术2016,39,8:3
5云南疣柄牛肝菌属真菌中汞含量及食用健康风险分析显示文摘汞(Hg)对人类健康有明显的毒害作用,多数野生食用菌对Hg有很强的富集能力,测定野生食用菌中总Hg含量,并对其进行食用安全评估有重要意义。采用冷原子吸收光谱法测定云南常见疣柄牛肝菌属真菌菌盖、菌柄中总汞(Hg)含量,分析样品对Hg的富集特征;以FAO/WHO现行每周Hg允许摄入量(provisional tolerable weekly intake,PTWI)标准,评估疣柄牛肝菌属真菌的食用安全性。结果显示,不同产地、种类及不同采集时间疣柄牛肝菌属真菌的总Hg含量差异明显,菌盖中总Hg含量在0.54~4.80 mg·kg-1dw之间,菌柄总Hg含量在0.32~2.80 mg·kg^(-1)dw之间,同一种牛肝菌菌盖总Hg含量均大于菌柄(Q(C/S)>1),表明疣柄牛肝菌属真菌对Hg的积累量与生长环境、种类、部位等有关。根据FAO/WHO暂行的每周Hg允许摄入量标准(0.004 mg·kg-1bw),成年人(60 kg)每周食用300 g(鲜重)采自云南的疣柄牛肝菌属真菌,Hg摄入量远低于PTWI标准,对人体Hg暴露风险较低。杨天伟 张霁 Jerzy Falandysz Gra.zyna Krasińska Martyna Saba 王元忠 2016生态毒理学报2016,11,3:3
6Hollow-core antiresonant terahertz fiber-based TOPAS extruded from a 3D printer using a metal 3D printed nozzle显示文摘We report the use of a terahertz(THz)transparent material,cyclic olefin copolymer(COC or TOPAS),for fabricating a hollow-core antiresonant fiber that provides an electromagnetic wave guidance in the THz regime.A novel fabrication technique to realize a hollow-core antiresonant polymer optical fiber(HC-ARPF)for THz guidance is proposed and demonstrated.The fiber is directly extruded in a single-step procedure using a conventional fused deposition modeling 3 D printer.The fiber geometry is defined by a structured nozzle manufactured with a metal 3 D printer,which allows tailoring of the nozzle design to the various geometries of microstructured optical fibers.The possibility to use the HC-ARPF made from TOPAS for guiding in the THz region is theoretically and experimentally assessed through the profile of mode simulation and time-frequency diagram(spectrogram)analysis.WANVISA TALATAISONG JON GORECKI LIEKE D.VAN PUTTEN RAND ISMAEEL JAMES WILLIAMSON KATIE ADDINALL DANIEL SCHWENDEMANN MARTYNAS BERESNA VASILIS APOSTOLOPOULOS GILBERTO BRAMBILLA 2021Photonics Research2021,9,8:2
