| 1 | Emotional regulation of pain:the role of noradrenaline in the amygdala显示文摘The perception of pain involves the activation of the spinal pathway as well as the supra-spinal pathway,which targets brain regions involved in affective and cognitive processes.Pain and emotions have the capacity to influence each other reciprocally;negative emotions,such as depression and anxiety,increase the risk for chronic pain,which may lead to anxiety and depression.The amygdala is a key-player in the expression of emotions,receives direct nociceptive information from the parabrachial nucleus,and is densely innervated by noradrenergic brain centers.In recent years,the amygdala has attracted increasing interest for its role in pain perception and modulation.In this review,we will give a short overview of structures involved in the pain pathway,zoom in to afferent and efferent connections to and from the amygdala,with emphasis on the direct parabrachio-amygdaloid pathway and discuss the evidence for amygdala’s role in pain processing and modulation.In addition to the involvement of the amygdala in negative emotions during the perception of pain,this brain structure is also a target site for many neuromodulators to regulate the perception of pain.We will end this article with a short review on the effects of noradrenaline and its role in hypoalgesia and analgesia. | STROBEL Cornelia HUNT Sarah SULLIVAN Robert SUN JianYuan SAH Pankaj | 2014 | Science China(Life Sciences)2014，57，4： | 7 |

| 3 | Versatile aza-BODIPY-based low-bandgap conjugated small molecule for light harvesting and near-infrared photodetection显示文摘The versatile nature of organic conjugated materials renders their flawless integration into a diverse family of optoelectronic devices with light-harvesting,photodetection,or light-emitting capabilities.Classes of materials that offer the possibilities of two or more distinct optoelectronic functions are particularly attractive as they enable smart applications while providing the benefits of the ease of fabrication using low-cost processes.Here,we develop a novel,multi-purpose conjugated small molecule by combining boron-azadipyrromethene(aza-BODIPY)as electron acceptor with triphenylamine(TPA)as end-capping donor units.The implemented donor–acceptor–donor(D–A–D)configuration,in the form of TPA-azaBODIPY-TPA,preserves ideal charge transfer characteristics with appropriate excitation energy levels,with the additional ability to be used as either a charge transporting interlayer or light-sensing semiconducting layer in optoelectronic devices.To demonstrate its versatility,we first show that TPA-azaBODIPY-TPA can act as an excellent hole transport layer in methylammonium lead triiodide(MAPbI3)-based perovskite solar cells with measured power conversion efficiencies exceeding 17%,outperforming control solar cells with PEDOT:PSS by nearly 60%.Furthermore,the optical bandgap of 1.49 eV is shown to provide significant photodetection in the wavelength range of up to 800 nm where TPA-azaBODIPY-TPA functions as donor in near-infrared organic photodetectors(OPDs)composed of fullerene derivatives.Overall,the established versatility of TPA-azaBODIPY-TPA,combined with its robust thermal stability as well as excellent solubility and processability,provides a new guide for developing highly efficient multi-purpose electronic materials for the next-generation of smart optoelectronic devices. | Gurudutt Bhat Marcin Kielar Haixia Rao Mahnaz D.Gholami Isabel Mathers Astrid C.R.Larin Thomas Flanagan Enkhtur Erdenebileg Annalisa Bruno Amandeep Singh Pannu Kathryn E.Fairfull-Smith Emad L.Izake Pankaj Sah Yeng Ming Lam Ajay K.Pandey Prashant Sonar | 2022 | InfoMat2022，4，12： | 0 |
