| 1 | Quantum dots assisted in vivo two-photon microscopy with NIR-Ⅱemission显示文摘With the advantages of high resolution and deep penetration depth,two-photon excited NIR-Ⅱ(900–1880 nm)fluorescence(2PF)microscopic bioimaging is promising.However,due to the lack of imaging systems and suitable probes,few such works,to our best knowledge,were demonstrated utilizing NIR-II excitation and NIR-Ⅱfluorescence simultaneously.Herein,we used aqueously dispersible Pb S/Cd S quantum dots with bright NIR-II fluorescence as the contrast agents.Under the excitation of a 1550 nm femtosecond(fs)laser,they emitted bright 2 PF in the NIR-Ⅱregion.Moreover,a 2PF lifetime imaging microscopic(2PFLIM)system was implemented,and in vivo 2PFLIM images of mouse brain blood vessels were obtained for the first time to our best knowledge.To improve imaging speed,an in vivo two-photon fluorescence microscopy(2 PFM)system based on an In Ga As camera was implemented,and in vivo 2PFM images of QDs-stained mouse brain blood vessels were obtained. | HUWEI NI YALUN WANG TAO TANG WENBIN YU DONGYU LI MUBIN HE RUNZE CHEN MINGXI ZHANG JUN QIAN | 2022 | Photonics Research2022，10，1： | 3 |
| 2 | Oxidative exfoliation of spent cathode carbon:A two-in-one strategy for its decontamination and high-valued application显示文摘Spent cathode carbon(SCC)from aluminum electrolysis is a potential graphite resource.However,full use of the SCC remains a challenge,since it contains many hazardous substances(e.g.,fluoride salts,cyanides),encapsulated within the thick carbon layers and thus posing serious environmental concerns.This work presents a chemical oxidative exfoliation route to achieve the recycling of SCC and the decontaminated SCC with high-valued graphene oxide(GO)-like carbon structures(SCC-GO)is applied as an excellent adsorbent for organic pollutants.Specifically,after the oxidative exfoliation,the embedded hazardous constituents are fully exposed,facilitating their subsequent removal by aqueous leaching.Moreover,benefiting from the enhanced specific surface areas along with abundant O-containing functional groups,the as-produced SCC-GO,shows an adsorption capacity as high as 347 mg·g^(-1)when considering methylene blue as a pollutant model,which exceeds most of the recently reported carbon-based adsorbents.Our study provides a feasible solution for the efficient recycling of hazardous carbonaceous wastes. | Runze Chen Yuran Chen Xuemin Liang Yapeng Kong Yangyang Fan Quan Liu Zhenyu Yang Feiying Tang Johnny Muya Chabu Maru Dessie Walle Liqiang Wang | 2023 | Chinese Journal of Chemical Engineering2023，59，7： | 0 |
| 3 | Targeted PERK inhibition with biomimetic nanoclusters confers preventative and interventional benefits to elastase-induced abdominal aortic aneurysms显示文摘Abdominal aortic aneurysm(AAA)is a progressive aortic dilatation,causing~80%mortality upon rupture.Currently,there is no approved drug therapy for AAA.Surgical repairs are invasive and risky and thus not recommended to patients with small AAAs which,however,account for~90%of the newly diagnosed cases.It is therefore a compelling unmet clinical need to discover effective non-invasive strategies to prevent or slow down AAA progression.We contend that the first AAA drug therapy will only arise through discoveries of both effective drug targets and innovative delivery methods.There is substantial evidence that degenerative smooth muscle cells(SMCs)orchestrate AAA pathogenesis and progression.In this study,we made an exciting finding that PERK,the endoplasmic reticulum(ER)stress Protein Kinase R-like ER Kinase,is a potent driver of SMC degeneration and hence a potential therapeutic target.Indeed,local knockdown of PERK in elastase-challenged aorta significantly attenuated AAA lesions in vivo.In parallel,we also conceived a biomimetic nanocluster(NC)design uniquely tailored to AAA-targeting drug delivery.This NC demonstrated excellent AAA homing via a platelet-derived biomembrane coating;and when loaded with a selective PERK inhibitor(PERKi,GSK2656157),the NC therapy conferred remarkable benefits in both preventing aneurysm development and halting the progression of pre-existing aneurysmal lesions in two distinct rodent models of AAA.In summary,our current study not only establishes a new intervention target for mitigating SMC degeneration and aneurysmal pathogenesis,but also provides a powerful tool to facilitate the development of effective drug therapy of AAA. | Nisakorn Yodsanit Takuro Shirasu Yitao Huang Li Yin Zain Husain Islam Alexander Christopher Gregg Alessandra Marie Riccio Runze Tang Eric William Kent Yuyuan Wang Ruosen Xie Yi Zhao Mingzhou Ye Jingcheng Zhu Yi Huang Nicholas Hoyt Mengxue Zhang John A.Hossack Morgan Salmon K.Craig Kent Lian-Wang Guo Shaoqin Gong Bowen Wang | 2023 | Bioactive Materials2023，，8： | 0 |
