Liver ischaemic preconditioning (IPC) is known to protect the liver from the detrimental effects of ischaemic-reperfusion injury (IRI), which contributes significantly to the morbidity and mortality following major liver surgery. Recent studies have focused on the role of IPC in liver regeneration, the precise mechanism of which are not completely understood. This review discusses the current understanding of the mechanism of liver regeneration and the role of IPC in this setting. Relevant articles were reviewed from the published literature using the Medline database. The search was performed using

Journal of Materials Science and Chemical Engineering 2016年第2期4卷 32-39页

作者： David Klein Wiebke Ohm Martin krü ger Marinus Kunst Helmholtz-Zentrum Berlin fü r Materialien und Energie Institute Solar Fuels (E-IF) Berlin Germany Helmholtz-Zentrum Berlin fü r Materialien und Energie Institut f&uuml r Heterogene Materialsysteme (E-IH) Berlin Germany

In this paper, contactless transient photo-conductance measurements are applied to p-doped mono-crystalline Silicon (p-Si) coated by two different kinds of aluminum oxide (Al2O3) layers in order to study alternative routes to the standard atomic layer deposition (ALD). The aluminum oxides layers were deposited by either spin coating or ion layer gas reaction (ILGAR?). For both coatings an increase of the charge carrier life time is observed indicating a passivation of the p-Si surface. This study shows alternative deposition methods and the potential of transient photocon- ductance measurements for the elucidation of the origin of the passivation. We show that the passivation induced by coating deposited via ILGAR is at least partially due to charge carrier trapping and storage at the interface. It was also surprisingly found that for those coatings, annealing at 425℃ leads to a decrease of the life time. This points to temperature instability for both coatings.

表情是人类社会交互中非言语交流的重要部分。而文化背景对这些表情的出现和发展起到重要的作用。另外,个体是旁观者观察或是处于社会交互当中也会影响他对不同情绪的知觉。本研究着眼于东方文化下社会交互对表情的表达和再认的影响,以及个体对不同文化背景个体的情绪知觉异同。本研究招募了20名中国大学生被试,其中10名男性,其余为女性。实验中被试观看一系列的视频片段,视频中为一张虚拟的东方人或西方人面孔展现愤怒(负性)或愉悦(正性)表情,其中一半视频中虚拟人物正面朝向被试且目光与被试接触,另一半视频中虚拟人物头部朝向侧向30度,且目光不与被试接触。实验中要求被试对该表情的效价在4点量表上进行评分。结果显示,当虚拟人物目光与被试接触时,相比于目光不接触,被试对情绪的判断更为极端(对愤怒情绪判断为更负性,对愉悦情绪判断为更正性)。另外,当虚拟人物为西方面孔时,相比于东方面孔,被试被试对情绪的判断更为极端(对愤怒情绪判断为更负性,对愉悦情绪判断为更正性)。另外,无论对于愤怒还是愉悦表情,女性被试的效价打分均要低于男性,即判断为更正性。本研究表明目光与个体的文化背景均会对情绪知觉产生影响。当个体处于社会交互当中时,对情绪的感知更为强烈,同时个体对异族个体的情绪感知也更为强烈。
