Ismail A. H. Muhammad,AL-Oqla Faris M.,Risby M. S.,Sapuan S. M. 한국탄소학회 2022 Carbon Letters Vol.32 No.3
Rapid development of carbon nanotubes (CNTs) reinforced to polymer composites has been recently noticed in many aspects. In this work, the latest developments on fatigue and fracture enhancement of polymer composites with CNTs reinforcement with diverse methods are thoroughly compiled and systematically reviewed. The existing available researches clearly demonstrate that fatigue fracture resistance of polymer composites can be improved accordingly with the addition of CNTs. However, this work identifies an interesting research gap for the first time in this field. Based on the systematic reviewing approach, it is noticed that all previously performed experiments in this field were mostly focused upon studying one factor only at a time. In addition, it is also addressed that there were no previous studies reported a relationship or effect of one factor upon others during examining the fatigue fracture of carbon nanotubes. Moreover, there was no adequate discussion demonstrating the interaction of parameters or the influence of one parameter upon another when both were examined simultaneously. It is also realized that the scope of the conducted fatigue fracture studies of carbon nanotubes were mainly focused on microscale fatigue analysis but not the macroscale one, which can consider the effect of environment and service condition. In addition, the inadequacy of fatigue life predicting models via analytical and numerical methods for CNT-reinforced polymer composites have also been highlighted. Besides, barriers and challenges for future directions on the application of CNT-reinforced polymer composite materials are also discussed here in details.

Effects of Various Stimuli on Corticotropin-Releasing Factor in the Human Neuroblastoma Clones
Han, Jin-Hee,Kasckow, John W.,Lee, Sung-Pil,Parkes, David G.,Owens, Michael J.,Stipetic, Mark D.,Risby, Emile,Nemeroff, Charles B. The Korean Society of Biological Psychiatry 1995 생물정신의학 Vol.2 No.2
Corticotropin-releasing factor(CRF)를 분비하는 배양세포주는 CRF의 세포내 조절을 연구하는데 있어 훌륭한 체계가 된다. BE(2)-M17 및 BE(2)-C 세포주는 CRF를 생산하고 분비하며 forskolin 처치에 반응하는 것으로 알려져 있다. 저자들은 이들 세포주에 phorbol 에스테르, 즉 phorbol 12-myristate 13-acetate(TPA) 0.8, 4, 10, 20 nM, 및 nitric oxide(NO)의 신호전달 경로의 자극제(1-${\mu}M$ nitroprusside)와 차단제($1{\mu}M$ nitroprusside+$300{\mu}M$ $N^G$-methyl-D-arginine), 그리고 interleukin-$1{\alpha}$ (IL $1{\alpha}$ ; 4, 20, 100, 500 pM)를 처치하여 CRF를 의미있게 증가시켰으나 세포외 분비는 C 세포에서만 변화되었다. NOS계의 자극제와 차단제는 C 세포의 forskolin 효과를 의미있게 변화시켰다. IL$1{\alpha}$는 두 세포주에 대한 영향이 없었다. 상기 제제들에 대한 이들 세포의 반응이 중추신경계 CRF 신경들과 관련하여 논의되었다.
