《日用家当》——美国黑人文学双重文化的反映

美国黑人文学既继承了非洲的文化传统又成长于美国文明的土壤中,有着双重文化的特点,本文通过对美国黑人文学《日用家当》的分析,透视了黑人文学中双重文化的特点.     

我国现阶段毒品犯罪原因分析

提出改革开放之初防毒机制的弱化 ,部分地区经济极度贫困 ,现实庞大“消费市场”的刺激是我国毒品犯罪发展蔓延的主要国内因素 ,国际毒品犯罪的日趋猖獗及毒品犯罪分子对巨额利润的贪婪追求也是我国现阶段的毒品犯罪发展的重要原因     

激情燃烧的艺术--林建勋书法印象

林建勋的书法倾注了艺术的真诚,其代表作<孙子兵法竹刻长卷>耗费时间最长、投入精力最多.林建勋的书法既富于刺激性,又不乏耐看性在字体选择上,他嗜狂草;在幅式选择上,他多取鸿篇巨制;在风格塑造上,他重气势的表现;在创作上,他纵心而不逾规矩;在形式上,他寓多样于统一之中;在格调上,其作品狂而不怪,犷而不野.     

MATLAB在地球物理专业《磁法勘探》课程教学中的应用

《磁法勘探》是一门理论性和实践性较强的地球物理专业课程。由于课程内容抽象,不易理解,如果仅通过理论课程很难系统地认识磁法勘探和数据处理过程,所以本研究将计算机软件MATLAB融入本课程教学中,不仅加深学生对理论知识的理解,更能培养学生编写代码、数据处理和解决实际问题的能力。     

个税流失成因及对策

个人所得税的流失有主观故意和客观必然两重原因 ,但最主要的是制度所致的客观原因。从主观角度看有纳税人的经济人本性原因 ;从客观角度言有历史的经济体制原因和征管制度不完善原因。针对不同原因 ,我们应该采取不同措施加以完善或要求制度本身作出重大调整 ,以使新的个人所得税制度更富有科学性、合理性、前瞻性和人性

CIDE gene expression in adipose tissue,liver, and skeletal muscle from obese and lean pigs

The expression of the cell death-inducing DNA fragmentation factor α-like effector (CIDE) family including Cidea, Cideb, and Cidec was significantly increased in mouse and human models of obesity. However, there was less information on these genes’ expression in pigs. Here, we hypothesized that different fat accumulation between lean (Duroc×Landrace×Yorkshire gilts, DLY) and obese (Lantang) pigs was attributed to porcine CIDE-modulating lipid metabolism. Our data showed that Cidea and Cidec were expressed at a high level in adipose tissue, and at a relatively high level in skeletal muscle, whereas Cideb was mainly expressed in the liver in both breeds of pig. Lantang pigs had higher white adipose and skeletal muscle Cidea and Cidec mRNA abundance, and hepatic and muscle Cideb mRNA than DLY pigs. Lipid metabolism-related genes including sterol regulatory element binding protein 1c (SREBP-1c), hepatocyte nuclear factor-4α (HNF-4α), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), fatty acid synthase (FASN), diacylglycerol O-acyltransferase 1 (DGAT1), and DGAT2 showed a higher expression level in adipose tissue from obese pigs than in that from lean pigs. Lantang pigs exhibited higher mRNA abundance for liver SREBP-1c, HNF-4α, and PGC-1α, and higher skeletal muscle SREBP-1c, HNF-4α, PGC-1α, and DGAT2 expression, as compared with DLY pigs. However, the perlipin2 mRNA levels in adipose tissues, liver, and skeletal muscle were significantly lower in obese pigs than in their lean counterparts. Furthermore, plasma non-esterified fatty acid (NEFA), glucose, and triacylglycerol (TAG) levels were greater in obese pigs than in lean pigs. Finally, data from correlation analysis further found that CIDE mRNA expression was positively correlated with back fat thickness (BFT), abdominal fat mass (AFM), and the levels of NEFA, TAG, and glucose in the two breeds. Collectively, these data revealed that the porcine CIDEs possibly modulated lipid metabolism and contributed to the development of fat deposition and obesity in Lantang pigs.

王灼诗文辑佚

南宋王灼的《颐堂先生集》完本近六十卷，今存五卷不足。前人对王灼的佚诗佚多有搜辑，近年北京大学之《全宋诗》、四川大学之《全宋》所收王灼诗最为完备，但亦收罗未尽。本钩稽历来诸家漏辑的王灼诗、十二篇。
