概述:抑郁障碍是目前最常见的心理健康问题之一。然而,对于该疾病的基于机制的治疗方法仍然是难以捉摸的。重复经颅磁刺激(rTMS)是一种非侵入性的程序,它可以以一种脉冲磁场来刺激大脑中的电活动,被认为是一种有效的抑郁症治疗方式。在... 概述:抑郁障碍是目前最常见的心理健康问题之一。然而,对于该疾病的基于机制的治疗方法仍然是难以捉摸的。重复经颅磁刺激(rTMS)是一种非侵入性的程序,它可以以一种脉冲磁场来刺激大脑中的电活动,被认为是一种有效的抑郁症治疗方式。在这里,我们回顾了关于rTMS治疗抑郁症的临床和基础研究的主要发现,包括它的抗抑郁疗效,基本原理,调节神经回路、神经递质和脑网络、海马神经发生、和突出的功效,以及分子通路。 展开更多

Developing high-strength Al-(La,Ce)alloys for additive manufacturing(AM)would entail considerable economic benefits.In this work,a novel near-eutectic Al-La alloy containing 5.50 wt.%Mg and 0.60 wt.%Mn was designed and fabricated via selective laser melting(SLM).Submicron Al_(11)La_(3)intermetallics with 3D continuous cellular-dendritic and granular morphologies were observed at the interior and boundary of the melt pool,respectively.Interestingly,these intermetallics are hierarchical and contained numerous Al_(6)Mn and Mg_(2)Si secondary nanoprecipitates.The as-fabricated alloy exhibited a tensile yield strength(YS)of 334 MPa and ultimate tensile strength(UTS)of 588 MPa at room temperature,which is the high-est UTS reported for Al-(La,Ce)alloys with an appreciable failure strain of∼6.4%.The 3D continuous cellular dendritic intermetallic and high Mg content afford significant strengthening and work harden-ing ability.In addition,the hierarchical feature of the intermetallics generated additional microcracks to coordinate the deformation. 展开更多
