大鼠急性脑干损伤神经细胞凋亡和轴突的变化

目的研究急性脑干损伤早期的病理变化,探讨其在急性脑干损伤中的法医学意义。方法采用自由落体造成大鼠急性脑干损伤模型,HE染色常规观察各部位脑组织的显微形态改变之后,用TUNEL末端标记检测神经细胞凋亡,用LSAB染色显示神经丝蛋白(NF)。结果实验动物模型能够较好的模拟法医案例;脑干损伤的大鼠脑组织淤血、水肿、环状出血,脑皮质内神经凋亡细胞数目明显增多(P<0.01);脑干部位神经轴突排列紊乱、肿胀、断裂。结论上述多种病理变化对急性脑干损伤的死后诊断具有一定的意义。     

头部受力后导致脑肿胀并发TNH的相互关系

目的探讨头部受力后导致脑肿胀并发TNH的相互关系。方法采用福尔马林固定的91例大脑标本,根据脑的损伤特点分三组分别作冠、矢及水平状切面,肉眼观察。结果发现脑损伤致脑肿胀后产生的TNH有三种类型,即前位疝65例(71.4％),后位疝5例(5.5％),及单、双侧全疝21例(23.1％)。其中16例全疝仍见以前位疝最显著。结论头部受力后易在额颞部发生前位疝。TNH虽与受力部位、受力机制有一定关系,但仍与受力强度、伤后存活时间关系密切。     

陕西省高新产业集群化发展战略分析

我国高新产业集群化发展中有一定的经验,但还存在一些问题。陕西省高新产业集群化发展的战略应从集群自身功能的完善、政府职能的定位和建立有效的资本运作机制采取战略措施。     

卵丘细胞对小鼠卵母细胞体外成熟及其后续发育的影响

观察了卵丘细胞共培养对小鼠生发泡期部分裸露(PNO)和裸卵(NO)成熟和发育能力的影响;分别用小鼠、大鼠、猪的卵丘细胞与小鼠PNO和NO进行了共培养。检测了小鼠PNO和NO的减数分裂能力、生发泡构型、受精和胚胎发育能力。结果,PNO、NO的减数分裂能力显著(P<0.05)低于卵丘完整复合体(COCs)的减数分裂能力。COCs中SN型卵母细胞比率显著高于PNO和NO中SN型卵母细胞比率(P<0.05),大部分PNO和NO的卵母细胞核型为NSN型。与对照组相比,与小鼠或大鼠卵丘细胞共培养的小鼠PNO和NO的减数分裂能力没有显著提高,但是与猪卵丘细胞共培养却可以提高小鼠PNO和NO的减数分裂能力。结果表明,猪卵丘细胞能促进小鼠卵母细胞的体外成熟,但并不影响小鼠卵母细胞的受精和胚胎发育。     

Smallest-space analysis vs. the method of principal components: Another look at Ahamad's analysis of crimes

This paper presents a reanalysis of the Ahamad case study of 18 types of offenses. The suggested method is a nonmetric multidimensional scaling type called smallest-space analysis (SSA-I) which uncovers findings that were not expressed explicitly by the principal-components method used by Ahamad.     

空肠弯杆菌肠毒素细胞检测法的建立

中国仓鼠卵巢细胞（ＣＨＯ），非洲绿猴肾细胞（Ｖｅｒｏ），人宫颈癌细胞（Ｈｅｌａ）和乳仓鼠肾细胞（ＢＨＫ－２１）４种细胞对空肠弯杆菌（Ｃａｍｐｙｌｏｂａｃｔｅｒｊｅｊｕｎｉ）细胞紧张性肠毒素（ＣｙｔｏｔｏｎｉｃＥｎｔｅｒｏｔｏｘｉｎ，ＣＥ）的敏感性试验表明，ＣＨＯ细胞对ＣＥ敏感；ＣＨＯ细胞与大鼠肠袢试验比较检测ＣＥ，以ＣＨＯ细胞对ＣＥ最敏感；试验发现布氏肉汤对细胞有毒性作用，确定了以Ｍ１９９＋１０ｇ／Ｌ胰蛋白胨培养基进行空肠弯杆菌产生ＣＥ的培养方法，依次建立了ＣＥ的ＣＨＯ细胞检测法。     

论动产让与担保与动产抵押之雷同--兼评我国民法(草案)对动产让与担保与动产抵押的规定

让与担保在物权化之后,与动产抵押在功能、性质、设定、公示等各方面完全相同,面临同样难以圆满解决的公示等难题.在考察大陆法系各国立法例的基础上可以发现,让与担保产生的直接原因就在于动产抵押制度的缺位.在适用范围一致的前提下,两者既没有共存的必要,也不具有共存的可行性.动产与不动产存在质的差别,动产抵押制度的存在并没有造成抵押权理论的混乱,更不会破坏民法物权体系的完整性.废除动产抵押制度无助于问题的解决,反而徒增制度变革的成本.动产抵押在我国已成为担保债权的重要手段,对社会经济发展也已有相当程度的贡献,故我国应进一步完善动产抵押制度而不移植让与担保.     

体外DNA扩增技术鉴定血痕性别三例报告

本文报道用体外DNA扩增技术对3例刑事案中的人血痕标本进行性别鉴定。其方法是从血痕标本中微量抽提DNA,用蛋白酶K进行消化。然后用两组引物Y1.1与Y1.2和Alu9.1与Alu9.2及国产FD耐热DNA聚合酶进行聚合酶链反(PCR)扩增DNA,电泳分析Y及Alu重复序列,从而判断血痕的性别。     

Inter-ethnic (In)tolerance between Turks and Kurds: Implications for Turkish Democratisation

Using public opinion survey data, this study investigates the determinants of inter-ethnic (in)tolerance among Turks and Kurds in Turkey. Our empirical analyses show that, compared with Turks, Kurds have a relatively higher level of tolerance towards the ethnic out-group. Our findings also suggest that different dynamics and factors mould Turks’ and Kurds’ tolerance towards ethnic out-group members. Religiosity, (ethno)nationalist orientations, inter-ethnic contact, threat perception and economic factors are the most consistent variables shaping Turks’ tolerance towards Kurds. In contrast, religion-related factors and inter-ethnic social contact do not have a statistically significant effect on Kurds’ tolerance towards Turks. (Ethno)nationalist orientations, however, appear to reduce Kurds’ tolerance.     

Collecting on their investments,one woman at a time: Economic partnerships among Caribbean immigrant women in the United States

ABSTRACT

This article treats rotating savings and credit associations (ROSCAs) from a constructive cultural perspective. The female-based African-Jamaican tradition of paadna (partnership) is examined within the theoretical scope of womanist (Black feminist) thought, a seminal discourse intersecting both the African diaspora and women's studies. Across the multiple scholarly approaches within women's and African diaspora studies, academic theory acquires cogency through legitimate correspondences with tangible liberating practices and traditions that can be documented and interrogated for conceptual insights. The practice of economic partnering is one such tradition that substantiates the ethical directives and imperatives of womanist theory and practice. A womanist reading of paadnas is proposed, not because the participants have any self-conscious commitment to feminism/womanism, but because of the institution's efficacy in enhancing the socioeconomic standing of Black families through a relatively small-scale capital enterprise. Through paadna networks, Jamaican women have transplanted a flexible self-help tradition to America that is arguably one of the most reliable sources of social and economic mobility among groups of African descent in the United States.
