Cellular internalization of proinsulin C-peptide

Proinsulin C-peptide is known to bind specifically to cell membranes and to exert intracellular effects, but whether it is internalized in target cells is unknown. In this study, using confocal microscopy and immunostained or rhodamine-labeled peptide, we show that C-peptide is internalized and localized to the cytosol of Swiss 3T3 and HEK-293 cells. In addition, transport into nuclei was found using the labeled peptide. The internalization was followed at 37°C for up to 1 h, and was reduced at 4°C and after preincubation with pertussis toxin. Hence, it is concluded to occur via an energy-dependent, pertussis toxin-sensitive mechanism and without detectable degradation within the experimental time course. Surface plasmon resonance measurements demonstrated binding of HEK-293 cell extract components to C-peptide, and subsequent elution of bound material revealed the components to be intracellular proteins. The identification of C-peptide cellular internalization, intracellular binding proteins, absence of rapid subsequent C-peptide degradation and apparent nuclear internalization support a maintained activity similar to that of an intracrine peptide hormone. Hence, the data suggest the possibility of one further C-peptide site of action. Received 31 October 2006; received after revision 27 December 2006; accepted 30 December 2006

Functional magnetic resonance imaging of amphetamine craving

The aim of this study is to identify the brain activity associated with amphetamine craving for understanding the neurobiology of addiction by watching pictures of happy, sad or amphetamine. Brain activity was measured in 12 amphetamine addicts and 12 healthy subjects by fMRI while the subjects watched pictures designed to elicit happy feelings, sad feelings, or the desire to use amphetamine. The result demonstrated that amphetamine cues led to abnormally high cingulate and low frontal lobe activation in amphetamine addicts, who showed abnormalities in affect-related brain activation.     

Co2+离子在CsMgCl3晶体中的g因子和超精细结构常数研究

用基团模型的3d^7离子在三角对称下的高阶微扰公式计算了CsMgCl3晶体中Co^2＋杂质中心的g因子g∥,g⊥和超精细结构常数A∥和A⊥。计算中，不仅考虑了基态和激发态间的组态相互作用效应，而且考虑了3d^7离子d轨道与配体p轨道之间的共价效应，与这两种效应相关的参数可由所研究晶体的光谱和结构数据得到。在考虑了键长与键角的微弱畸变后，理论计算值与实验观测值符合较好。

牡丹与寒梅:以两种花卉阐释唐宋士人的差异

在中国古代,历来有花卉鸟兽抒情明志的传统。在特定历史时期中,某种自然物象同特定的情感和意义之间建立了相对稳固的关系,经过社会的认同,物象便转化为人的情感符号而失去了自身客观性质的特征而成为时代的一种标志。牡丹与寒梅就是唐宋两代士人给予充分观照的审美对象,前者艳绚丽、神采外放,代表了唐代建功立业、开张扬厉的时代精神;后者瞿瘦淡雅,外枯中膏,可与宋人淡泊收敛,质朴深微的心态相契合。唐人爱牡丹,宋人重寒梅,从两种花卉的分析中,可对唐宋的时代精神加以阐释。
