1Multi-directionally wrinkle-able textile OLEDs for clothing-type displays显示文摘A clothing-type wearable display can be utilized in fashion,bio-healthcare,and safety industries as well as smart textiles for the internet of things(IoTs)and wearable devices.In response to this trend,we demonstrate a textile display that can endure the active movements of a human body.It can be applied to any kind of textile,and is durable against conditions such as rain,sweat,and washing.As a key technology for realizing the multi-directional wrinkle-able textile display,we fabricated a stress-lowering textile platform with an ultrathin planarization layer replicated from the flat surface of glass.An elastomeric strain buffer for reducing mechanical stress is also inserted into the textile platform.Here,organic light-emitting diodes(OLEDs)with red,green and blue color,thin film transistors(TFTs)fabricated at a low temperature below 150℃,and a washable encapsulation layer blocking both gas and liquid were demonstrated on the textile platform.Seungyeop Choi Woosung Jo Yongmin Jeon Seonil Kwon Jeong Hyun Kwon Young Hyun Son Junmo Kim Jun Hong Park Hyuncheol Kim Ho Seung Lee Minwoo Nam Eun Gyo Jeong Jeong Bin Shin Taek-Soo Kim Kyung Cheol Choi 2020npj Flexible Electronics2020,4,1:3
2Effects of Gastrodiae rhizoma on proliferation and differentiation of human embryonic neural stem cells显示文摘Objective:To investigate the effects of Gastrodiae rhizoma,a dried root of Gastrodia elata Blume,on proliferation and differentiation of human NSCs derived from embryonic stem cells.Methods:A 70%ethanol extract of Gastrodiae rhizoma(EEGR) was estimated with4-hydroxybenzyl alcohol as a representative constituent by HPLC.Results:MTT assay showed that the treatment with EEGR increased the viability of NSCs in growth media.Compared to contro1,EEGR increased the number of dendrites and denritic spines extended from a differentiated NSC.Whereas EEGR decreased the mRNA expression of Nestin,it increased that of Tuj1 and MAP2 in NSCs grown in differentiation media.Immunocytochemical analysis using confocal microscopy also revealed the increased expression of MAP2 in dendrites of EEGR-treated NSCs.Furthermore,EEGR decreased mRNA expression of Sox2 in NSCs grown even in growth media.Conclusions:In conclusion,our study demonstrates for the first time that EEGR induced proliferation and neuronal differentiation of NSCs,suggesting its potential benefits on NSC-based therapies and neuroregeneration in various neurodegenerative diseases and brain Injuries.Samrat Baral Ramesh Pariyar Chi-Su Yoon Dong-Cheol Kim Jong-Min Yun Seok O Jang Sung Yeon Kim Hyuncheol Oh Youn-Chul Kim Jungwon Seo 2015Asian Pacific Journal of Tropical Medicine2015,8,10:2

10Development of exosome membrane materialsfused microbubbles for enhanced stability and efficient drug delivery of ultrasound contrast agent显示文摘Lipid-coated microbubbles are widely used as an ultrasound contrast agent,as well as drug delivery carriers.However,the two main limitations in ultrasound diagnosis and drug delivery using microbubbles are the short half-life in the blood system,and the difficulty of surface modification of microbubbles for active targeting.The exosome,a type of extracellular vesicle,has a preferentially targeting ability for its original cell.In this study,exosome-fused microbubbles(Exo-MBs)were developed by embedding the exosome membrane proteins into microbubbles.As a result,the stability of Exo-MBs is improved over the conventional microbubbles.On the same principle that under the exposure of ultrasound,microbubbles are cavitated and self-assembled into nano-sized particles,and Exo-MBs are self-assembled into exosome membrane proteins-embedded nanoparticles(Exo-NPs).The Exo-NPs showed favorable targeting properties to their original cells.A photosensitizer,chlorin e6,was loaded into Exo-MBs to evaluate therapeutic efficacy as a drug carrier.Much higher therapeutic efficacy of photodynamic therapy was confirmed,followed by cancer immunotherapy from immunogenic cell death.We have therefore developed a novel ultrasound image-guided drug delivery platform that overcomes the shortcomings of the conventional ultrasound contrast agent and is capable of simultaneous photodynamic therapy and cancer immunotherapy.Yongho Jang Jeehun Park Pilsu Kim Eun-Joo Park Hyungjin Sun Yujin Baek Jaehun Jung Tai-kyong Song Junsang Doh Hyuncheol Kim 2023Acta Pharmaceutica Sinica B2023,13,12:1
