核盘菌多聚半乳糖醛酸酶基因的克隆及hpRNAi载体的构建 总被引:1,自引:0,他引:1
多聚半乳糖醛酸酶是核盘菌致病力发挥作用的关键酶。本研究用PCR的方法从核盘菌基因组DNA中扩增出多聚半乳糖醛酸酶(PG5)基因片段,再以扩增出的PG5基因片段作为模板设计引物扩增出一个相应较小的片段。将两个PG5基因片段反向插入到植物表达载体2300 sn的35S启动子和nos终止子之间,构建出可转录表达出发夹RNA结构的组成型油菜RNA干扰载体,为今后油菜利用RNA干扰抗菌核病的基因工程研究奠定了基础。 相似文献

本文选用新鲜的山苍子果实,用水蒸汽蒸馏法提取其中的山苍子油作为实验用油,通过采用Na2S2O3-I2滴定法,对山苍子油与公众最常食用的菜籽色拉油、芝麻油进行比较研究.发现在实验条件下,山苍子油的氧化稳定性不但超过菜籽色拉油,还超过氧化稳定性较强的芝麻油,其POV值在15天后才达到19.57 meq/kg. 相似文献

Rape incidents involving college students have recently gained national attention resulting in an open debate about whether a college environment is prone to sexual violence. Although studies show that most rape victims talked to friends or relatives and that the victims took their advice for the next action, few studies have examined the type of advice given by college students. A sample of undergraduate students was provided with vignettes describing a hypothetical rape situation and a series of questions about their belief in rape myths, attitudes toward women, and their individual characteristics and backgrounds. Findings suggest that the attribution of less responsibility to the victim, an acquaintance assailant, victim resistance, a belief in egalitarian views of women, men, and African-Americans, were associated with an increased likelihood of advice to contact the police. Implications are discussed with particular attention to the college population. 相似文献

以转IrrE基因油菜为材料,以非转基因油菜为对照,砂培条件下研究了油菜对Cs的积累吸收情况和Cs胁迫对油菜SOD、POD酶活性、MDA含量及游离脯氨酸含量的影响.结果表明:随着处理浓度的增大,转基因油菜和非转基因油菜对Cs的吸收量都增大,二者根部的吸收量都大于其地上部分;转基因油菜根部的积累量大于非转基因油菜根部的量,而地上部分积累量小于非转基因油菜的含量;在不同Cs浓度的胁迫下,转基因和非转基因叶片的SOD和POD活性均呈现先升后降的趋势,4种Cs浓度处理下转基因油菜活性都高于非转基因油菜;转基因和非转基因油菜叶片的MDA含量均呈上升的趋势,但转基因油菜体内的MDA含量都低于非转基因油菜;4种处理下油菜叶片脯氨酸含量也表现出上升趋势,而转基因油菜产生的游离脯氨酸高于非转基因产生的.以上结果说明在油菜受到Cs胁迫时,转IrrE基因油菜比非转基因油菜更具有Cs胁迫耐受性. 相似文献

OBJECTIVE: Our objective was to audit the provision and utilization of HIV post-exposure prophylaxis (PEP) to child rape survivors in the Province of KwaZulu-Natal, South Africa. METHODS: A prospective design was used to collect data from a convenience sample of 200 consecutive cases of child rape referred for medico-legal assessment to a state hospital located to the north of the City of Durban (South Africa) in the period October to December 2004. For each case, information was obtained regarding demographic characteristics of the child, the child's HIV status at presentation, any excluding factors for PEP therapy, and the extent of adherence to the antiretroviral therapy regimen. RESULTS: One hundred and twenty children (60%) qualified for PEP provision, with children being excluded because they refused initial HIV testing (1.5%), tested HIV positive at presentation (6.5%), or because of delayed (>72hour) presentation (32%). Of the 113 children who were followed through the PEP provision system, 40 (35.4%) returned for the full 28-day course, and only 4 (3.5%) returned at both 3- and 6-month follow up. CONCLUSIONS: Adherence rates for PEP therapy following child rape in South Africa are extremely low, with low adherence rates being associated with a theoretical risk of both reduced efficacy and drug resistance. In this context, there is a need for further research designed to identify the reasons for such non-adherence as well as a need for secondary prevention programs designed to both encourage more immediate reporting of child rape and to increase adherence to the PEP regimen. 相似文献

When the topic of sexual assault is presented in high school and college health courses, it is mostly from a prevention perspective. Rarely do such courses include the mental and emotional health issues suffered by the rape survivor. Knowledge about rape trauma syndrome helps significant people in the victim's life understand the full range of reactions to the traumatic experience of rape. This lesson describes survivors’ behaviors and reactions after a rape, otherwise known as rape trauma syndrome. Included in this lesson is the federal definition of rape, a summary of rape trauma syndrome, lyrics to a song with relevant applications to the phases of rape trauma syndrome, and a rubric for grading a reaction paper related to the lesson. Three National Health Education Standards are addressed via the lesson as well. 相似文献

Cases of rape, particularly date rape, have reached almost epidemic proportaions on college campuses throughout the country. In this article the author describes how he extended his role as a college pscyhotherapist in order to undertake activism in behalf of college date rape victims generally. The author as activist undertook two major courses of action: (1) The author as activist undertook two major courses of action: (1) Testified to the California State Legislature in support of Assemblyman Tom Hayden's bill dealing with college date rape; and (2) Appeared on a television news program that investigated the crime of college date rape. The author later utilized a video recording of the program in conjunction with a series of lectures he conducted on his campus regarding the subject of college date rape. 相似文献

莫里森通过《宠儿》这部复调式的小说,向我们揭示了在奴隶制语境中,奴隶们被强奸的历史和记忆带给他们“无法言说的”精神创伤。作者借用哥特式的叙事技巧,使“强奸”的隐喻意义得到了淋漓尽致的表达。种族至上的强势话语无疑是“强奸”隐喻的指称。 相似文献

由于我国《刑法》对强奸罪的主体没有明确规定,只是在第二百三十六条规定:以暴力、胁迫或者其他手段强奸妇女的,处三年以上十年以下有期徒刑。同时夫妻间又有复杂的同居关系,这就使丈夫能否成为强奸罪的主体成为一个争议。从学术界对婚内强迫性行为的几种观点出发,结合我国法律对强奸罪和家庭暴力的规定,认为丈夫的婚内强迫性行为应分情况而定,具体来说:在有瑕疵的婚姻关系中应定强奸罪,在无瑕疵的婚姻关系中应归入家庭暴力的范围由《婚姻法》调整。 相似文献

婚内强奸是从古至今普遍存在的一种社会现象,婚内强奸产生的原因,是妇女与男子在人权上的不平等。建议将婚内强奸犯罪化,只有加强和完善婚内绍奸的立法和司法工作,才能切实保障妇女的权利。 相似文献
