古诗词曲英译文化理论探索——鸟类文化意象的翻译

鸟类在古诗词曲里是一个重要的文化意象,用以表达诗人的喜乐哀愁。它们寓含丰富的文化,译者翻译时需放在文化语境里考虑。文章从文化角度探讨了鸟类文化意象诗歌的翻译方法,以向译语读者展现鸟类诗歌特殊的韵味,是古诗词跨文化翻译的一个尝试。     

高校课程考试改革在新疆少数民族地区的实践与探索

课程考试改革是高校教学改革的重要组成部分,西部少数民族地区民汉学生在学习上有一定差异,为适应教育教学发展的需要,以具体课程为例,根据民汉学生在学习中存在的差异,提出具体的课程考试改革方案并进行检验,通过课程考试的评价、激励、反馈与导向功能,从根本上影响学生对学习内容和学习方式的选择,为进一步深化和推进课程改革提供实践借鉴.     

Effect of interrupted endogenous BMP/Smad signaling on growth and steroidogenesis of porcine granulosa cells

Bone morphogenetic proteins (BMPs) play a critical role in the growth and steroidogenesis of granulosa cells (GCs). BMP signals act through membrane-bound heteromeric serine/threonine kinase receptors. Upon ligand binding, BMPs activate intracellular Smad proteins and regulate growth and apoptosis in various cell types. The objective of this study was to demonstrate the effects of BMP/Smad signal on growth and steroidogenesis of porcine GCs. A strategy of RNA interference (RNAi)-mediated ‘gene silencing’ of Smad4, a core molecule mediating the intracellular BMP/Smad signal transduction pathways, was used to interrupt endogenous BMP/Smad signaling. Results indicate that Smad4-small interfering RNA (siRNA) caused specific inhibition of Smad4 mRNA and protein expression after transfection. Interrupted endogenous BMP/Smad signaling significantly inhibited growth, and induced apoptosis of porcine GCs, while decreasing estradiol production. In addition, interrupted BMP/Smad signaling significantly (P<0.05) changed the expression of Cyclin D2, CDK4, Bcl-2, and Cyp19a1. These findings provide new insights into how BMP/Smad signaling regulates the growth and steroidogenesis of porcine GCs.

Metachronous contralateral testicular and bilateral adrenal metastasis of chromophobe renal cell carcinoma: a case report and review of the literature

Chromophobe renal cell carcinoma(ChRCC) metastatic to the testis has not,to the best of our knowledge,been reported in the literature.Nor have there been reports of delayed bilateral adrenal metastasis of ChRCC.Here we report a case of metachronous contralateral testicular and bilateral adrenal metastasis of ChRCC in a 70-year-old man who underwent right radical nephrectomy for RCC six years ago.He was admitted to the hospital because of left intrascrotal enlargement of two-month duration.Ultrasonography re...     

Mathematical models of canine right and left atria cardiomyocytes

The aim of this study is to build two mathematical models of canine ionic currents specific to right atria and left atria.The canine left atria mathematical model was firstly modified from the Ramirez-Nattel-Courtemanche(RNC) model using the recently available experimental data of ionic currents and was further developed based on our own experimental data.A model of right atria was then built by considering the differences between right atria and left atria.The two developed models well reproduced the exper...     

Science Letters:Proteomic analysis of differentially expressed proteins in mice with concanavalin A-induced hepatitis

Objective:To find new protein biomarkers for the detection and evaluation of liver injury and to analyze the relationship between such proteins and disease progression in concanavalin A (Con A)-induced hepatitis.Methods:Twenty-five mice were randomly divided into five groups:an untreated group,a control group injected with phosphate buffered saline (PBS),and groups with Con A-induced hepatitis evaluated at 1,3 and 6 h.Two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS) were used to identif...     

8-羟基喹啉铝纳米棒的制备及性能表征

以多孔氧化铝膜为模板,通过液-液接触沉淀法成功制备出大面积、高度有序的8-羟基喹啉铝的纳米棒阵列,并对其形貌、成份及荧光性能等进行了表征。结果表明,实验所得8-羟基喹啉铝纳米棒为非晶态结构,相对于8-羟基喹啉,其荧光强度显著增强,荧光峰的位置发生蓝移。

互联网与大学思想政治教育工作方法的实证分析

以班级和思想政治教育工作者作为考察的切入点,作者设计了面向全班同学包含了学生干部、班委成员在内的全体学生的问卷,同时还设计了面向全体思想政治教育者的问卷,辅以各种文献,对该班级成员对于互联网与大学生思想政治教育者的工作方法等进行了实证分析。结果表明,全班同学对于互联网的积极态度、期望思想政治教育工作者的素质提高等指标相对要高,表明互联网在思想政治教育工作方面有重要作用;通过全班同学对于互联网的热爱程度,我们认为在新时代要大力提高思想政治教育者的综合素质,以期能够在新形势下掌握好大学生的心理动态,提高思想政治工作的实效性,更好地为大学生服务。
