1Tunable catalytic activity of gadolinium-doped ceria nanoparticles for pro-oxidation of hydrogen peroxide显示文摘We report a study of the roles of gadolinium(lll)(Gd3+)dopants in influencing the catalytic activity of gadolinium-doped ceria nanoparticles towards the pro-oxidation of hydrogen peroxide to hydroxyl radicals.These doped ceria nanoparticles with dopant concentrations of 0.6 wt.%,3 wt.%,and 6 wt.%Gd^3+were synthesized using an ozone-mediated method for tuning their catalytic activities.The Gd dopants were found to foster an increase in the percentage of Ce^3+ions in the doped ceria nanoparticles.Our reaction kinetic study revealed that the relationship between the overall reaction rates and the Gd dopant concentrations in our doped materials followed a volcano-like trend.In contrast,the apparent activation energy values of these Gd-doped ceria nanoparticles were found to be positively associated with the concentrations of Gd dopants.The overall catalytic activity trend was attributed to the interplay between the promotion and degradation effects of the Gd dopants on the properties of doped ceria nanoparticles.Anuja Bhalkikar Tai-Sing Wu Tamra J.Fisher Anandakumar Sarella Dawei Zhang Yi Gao Yun-Liang Soo Chin Li Cheung 2020Nano Research2020,13,9:2

5Photodynamic therapy in the treatment of intracranial gliomas:A review of current practice and considerations for future clinical directions显示文摘Invasive grade III and IV maliguant gliomas remain difficult to treat with a typical survival time post-diagnosis hovering around 16 months with only minor extension thereof seen in the past decade,whereas some improvements have been obtained towards five-year survival rates for which completeness of resection is a prerequisite.Optical techniques such as fluorescence guided resection(FGR)and photodynamic therapy(PDT)are promising adjuvant techniques to in-crease the tumor volume reduction fraction.PDT has been used in combination with surgical resection or alternatively as standalone treat ment strategy with some sucoess in extending the median survival time of patients compared to surgery alone and the current standard of care.This document reviews the outcome of past clinical trials and highlights the general shift in PDT therapeutic approaches.It also looks at the current approaches for interstitial PDT and research options into increasing PDT's glioma treatment fficacy through exploiting both physical and biological based approaches to maximize PDT selectivity and therapeutic index,particularly in brain adjacent to tumor(BAT).Potential reasons for failing to demonstrate a significant survival advantage in prior PDT clinical trials will become evident in light of the improved understanding of glioma biology and PDT dosimetry.Carl J.Fisher Lothar Lilge 2015Journal of Innovative Optical Health Sciences2015,8,1:0
