浅析高校辅导员在大学生就业工作中的作用

随着高等院校的扩招,大学生数量的增加,大学生的就业难问题已经成为了当今社会关注的热点话题之一,本文就高校辅导员在大学生就业工作中的优势之所在和高校辅导员在大学生就业工作中的重要作用等方面做出了相应的论述。     

菌群失调症患者体内sICAM-1活性表达和血小板分布情况

探讨老年肠道功能性腹泻致菌群失调症时,患者血浆中可溶性细胞间粘附分子sICAM-1表达,以及外周血小板分布情况。我们检测了50例老年胃肠功能性腹泻所致菌群失调症患者的用药前与用药后的血浆可溶性细胞间粘附分子sICAM-1,凝血功能检测凝血酶原时间（PT）、活化部分凝血酶原时间（APTT）,并进行血浆纤维蛋白原测定,以及血小板光学散射分析,了解正常菌群分布对相关指标的影响。     

Governmental policies on HIV infection in China

EVOLUTION OF THE GOVERNMENT POLI- CIES Looking back 20 and more years, one could have hardly imagined that such great changes would have happened to the governmental policies on HIV/AIDS in China. In the earlier phase of the epidemic, laws and regulations were drafted based on the practices and experiences of preven- tion and control of other infectious diseases, such as isolation, quarantine and compulsory testing and examina- tions etc. When the HIV/AIDS epidemic was firstl…     

霍山石斛(Dendrobidium huoshanness)的组织培养

霍山石斛(Dendrobidium huoshanness)是重要的药用植物,在组培过程中,其营养器官脱分化困难.本文研究了霍山石斛拟原球茎(PLBs)诱导的适宜条件,发现假鳞茎下段是诱导拟原球茎适宜的外植体,低浓度的NAA和CPPU的诱导效果较好,黑暗培养可缩短诱导时间,提高诱导率.

A Computational Model of Soil Adhesion and Resistance for a Non-smooth Bulldozing Plate

1IntroductionAdhesive forces exist between soil and the surfacesof soil-engaging components[1,2].Soil adhesion increasesthe running resistance and energy consumption,andaffects the operating quality.Soil adhesion also reducesthe working productivity of terrain machines,even worseit makes terrain machines fail to run.Reducing theadhesive force of the soil-engaging machines will have aprofound influence for cultivation.Through theinvestigation of soil animals,we have found that soilanimals poss…     

A Stable Upstream Stem-loop Structure Enhances Selection of the First 5'-ORF-AUG as a Main Start Codon for Translation Initiation of Human ACAT1 mRNA

Acyl-coenzyme A:cholesterol acyltransferase (ACAT)is an integral membrane protein, which is mainly locatedin rough endoplasmic reticulum (ER), and is responsiblefor catalyzing the intracellular formation of cholesterylester from cholesterol and long-chain fatty acyl-coenzymeA [1,2]. Human ACAT1 cDNA K1 was firstly cloned andfunctionally expressed in 1993 [3]. Further studies withspecific anti-ACAT1 antibody (DM10) illustrated that onemajor 50 kD ACAT1 protein was expressed in various…
