Significati particolari di ἀπάτη e ἀπατάω nel greco koiné e l’interpretazione di ἀπατῶν καρδίαν αὐτοῦ in Gc 1,26

L.T. Johnson ha interpretado ἀπατῶν καρδίαν αὐτοῦ in Sant 1,26 como “indulging his heart”. La propuesta requiere una revisión de los casos en los que ἀπάτη y ἀπατάω tienen un significado diferente del original “engaño” / “engañar” en varias fuentes antiguas. La investigación ha conducido a la identificación de tres significados del verbo y del nombre, todos ellos relacionados con la semántica del placer y la diversión. En Sant 1:26 podemos admitir el significado de “dar placer” para ἀπατάω. Llegamos a la conclusión, sin embargo, que esta interpretación es muy poco probable y es preferible dar a ἀπατάω el sentido de “engañar”.

La_(1-x)Pr_xP_5O_(14)晶体的发光

Pr~(3+)离子的能级结构丰富,在紫外可见区有很好的荧光发射。因此,以Pr~(3+)为激活离子的发光材料研究工作引起了人们的关注。轻稀土五磷酸盐晶体结构为单斜晶系,空间群为P_(1/2)/C,稀土离子处在隔离的多面体中,离子间的作用减弱,即使在化学计量比的PrP_5O_(14)仍得到激光输出。本文采用水热法生长出La_(1-x)Pr_xP_5O_(14)

Ce_xGd_yTb_(1-x-y)P_5O_(14)晶体生长及其光谱

采用蒸发溶液法从磷酸溶液中生长出一系列Ce_xGd_yTb_(1-x-y)P_5O_(14)晶体.测定了它们的结构.它们属于单斜晶系,空间群P2_(1/c).测定了Ce_(0.9)Gd_(0.1)P_5O_(14)、Ce_(0.9)Tb_(0.1)P_5O_(14)和La_(0.8)Gd_(0.1)Tb_(0.1)P_5O_(14)等晶体的光谱.首次观察到,将Gd加入Ce_xTb_(1-x)P_5O_(14)晶体中形成.Ce_xGd_yTb_(1-x-y)P_5O_(14)时阻碍了Ce~(3+)→Tb~(3+)的能量传递,导致Ce~(3+)的发射峰增强,Tb~(3+)的~5D_4—~F_J发射峰减弱、而~5D_3—~7F_J发射峰增强.

Endothelin-converting enzyme-1 degrades internalized somatostatin-14

Agonist-induced internalization of somatostatin receptors (ssts) determines subsequent cellular responsiveness to peptide agonists and influences sst receptor scintigraphy. To investigate sst2A trafficking, rat sst2A tagged with epitope was expressed in human embryonic kidney cells and tracked by antibody labeling. Confocal microscopical analysis revealed that stimulation with sst and octreotide induced internalization of sst2A. Internalized sst2A remained sequestrated within early endosomes, and 60 min after stimulation, internalized sst2A still colocalized with beta-arrestin1-enhanced green fluorescence protein (EGFP), endothelin-converting enzyme-1 (ECE-1), and rab5a. Internalized (125)I-Tyr(11)-SST-14 was rapidly hydrolyzed by endosomal endopeptidases, with radioactive metabolites being released from the cell. Internalized (125)I-Tyr(1)-octreotide accumulated as an intact peptide and was released from the cell as an intact peptide ligand. We have identified ECE-1 as one of the endopeptidases responsible for inactivation of internalized SST-14. ECE-1-mediated cleavage of SST-14 was inhibited by the specific ECE-1 inhibitor, SM-19712, and by preventing acidification of endosomes using bafilomycin A(1). ECE-1 cleaved SST-14 but not octreotide in an acidic environment. The metallopeptidases angiotensin-1 converting enzyme and ECE-2 did not hydrolyze SST-14 or octreotide. Our results show for the first time that stimulation with SST-14 and octreotide induced sequestration of sst2A into early endosomes and that endocytosed SST-14 is degraded by endopeptidases located in early endosomes. Furthermore, octreotide was not degraded by endosomal peptidases and was released as an intact peptide. This mechanism may explain functional differences between octreotide and SST-14 after sst2A stimulation. Moreover, further investigation of endopeptidase-regulated trafficking of neuropeptides may result in novel concepts of neuropeptide receptor inactivation in cancer diagnosis.

There are no unusual bond distances or angles. The triazole and two phenyl rings are planar. On the basis of packing considerations the possibility of intermolecular interactions playing a role in the reactivity of the starting material is ruled out.

HIV-1感染对T和B细胞核内UNG2 mRNA表达的影响

目的:探讨HIV-1感染是否影响细胞中UNG2的表达.方法:采用四步法SYBR green Ⅰ实时定量RT-PCR,对HIV-1感染者的T和B淋巴细胞,以及HIV-1感染的C8166细胞核内UNG2 mRNA的表达进行测定.结果:UNG2 mRNA的表达在HIV-1感染者的T细胞和HIV-1感染的C8166细胞中被明显上调,分别是对照的8.76倍和8.14倍,而在HIV-1感染者的B细胞中却没有被上调.结论:HIV-1感染导致的UNG2表达上调,可能通过减少TCR的多样性削弱Th的功能,另一方面可能有利于病毒对UNG2的包装.
