1深部地球条件下铁和氧元素的化学变化显示文摘氧与铁分别为地球上丰度最高的元素与占地球质量最大的元素,它们所形成的化合物遍布我们的星球,具有-2价的氧控制着地球的氧逸度,随着深度的增加氧逸度逐渐降低,与铁所形成的氧化物中铁的价态也逐渐降低,O/Fe逐渐增加,近些年来科学家们发现深部地球条件下铁的一系列氧化物,其中具有高压黄铁矿结构的铁超氧化物FeO2具有最高的O/Fe,并且它还能够携带一定量的H(表示为Py-FeO2H,, x=0-1)。夏群科 Liu J Hu Q Y Bi W L Yang L X Xiao Y M Chow P Meng Y.Prakapenka V B Mao H K Mao W L 2019矿物岩石地球化学通报2019,38,3:2
2术中应用荧光素钠有利于胶质母细胞瘤浸润边缘的手术切除(英文)显示文摘Objective Extent of resection is an important prognostic factor in patients undergoing surgery for glioblastoma( GBM).Recent evidence suggests that intravenously administered fluorescein sodium associates with tumor tissue,facilitating safe maximal resection of GBM. In this study,the authors evaluate the safety and utility of intraoperative fluorescein guidance for the prediction of histopathological alteration both in the contrast-enhancing( CE) regions,where this relationship has been established,and into the nonCE( NCE),diffusely infiltrated margins. Methods Thirty-two patients received fluorescein sodium( 3 mg/kg) intravenously prior to resection. Fluorescence was intraoperatively visualized using a Zeiss Pentero surgical microscope equipped with a YELLOW 560 filter.Stereotactically localized biopsy specimens were acquired from CE and NCE regions based on preoperative MRI in conjunction with neuronavigation. The fluorescence intensity of these specimens was subjectively classified in real time with subsequent quantitative image analysis,histopathological evaluation of localized biopsy specimens,and radiological volumetric assessment of the extent of resection.Results Bright fluorescence was observed in all GBMs and localized to the CE regions and portions of the NCE margins of the tumors,thus serving as a visual guide during resection. Gross-total resection( GTR) was achieved in 84% of the patients with an average resected volume of 95%,and this rate was higher among patients for whom GTR was the surgical goal( GTR achieved in 93. 1% of patients,average resected volume of 99. 7%). Intraoperative fluorescein staining correlated with histopathological alteration in both CE and NCE regions,with positive predictive values by subjective fluorescence evaluation greater than 96% in NCE regions. Conclusions Intraoperative administration of fluorescein provides an easily visualized marker for glioma pathology in both CE and NCE regions of GBM. These findingssupport the use of fluorescein as a microsurgical adjunct for guiding GBM resection to facilitate safe maximal removal.Neira JA Ung TH Sims J Malone HR Chow DS Samanamud JL Zanazzi GJ Guo X Bowden SG Zhao B Sheth SA McKhann GM 2nd Sisti MB Canoll P D'Amico RS Bruce JN 2016中华神经外科疾病研究杂志2016,15,5:2
