Developmental validation of a Cannabis sativa STR multiplex system for forensic analysis

A developmental validation study based on recommendations of the Scientific Working Group on DNA Analysis Methods (SWGDAM) was conducted on a multiplex system of 10 Cannabis sativa short tandem repeat loci. Amplification of the loci in four multiplex reactions was tested across DNA from dried root, stem, and leaf sources, and DNA from fresh, frozen, and dried leaf tissue with a template DNA range of 10.0-0.01 ng. The loci were amplified and scored consistently for all DNA sources when DNA template was in the range of 10.0-1.0 ng. Some allelic dropout and PCR failure occurred in reactions with lower template DNA amounts. Overall, amplification was best using 10.0 ng of template DNA from dried leaf tissue indicating that this is the optimal source material. Cross species amplification was observed in Humulus lupulus for three loci but there was no allelic overlap. This is the first study following SWGDAM validation guidelines to validate short tandem repeat markers for forensic use in plants.

4种香茶菜属植物微性状特征研究

目的 研究香茶菜及同属植物微性状鉴别特征。方法 采用500万像素电子摄像目镜,应用景深合成技术合成微性状鉴别图片,观察4种香茶菜属植物的新鲜及干燥叶片的微性状特征。结果 在叶尖突起程度、毛茸的长短与分布方面,4种香茶菜属植物叶片的微性状有明显不同：岐伞香茶菜和显脉香茶菜密被较长毛茸,叶尖极度突起或明显突起;香茶菜和大萼香茶菜稀被较短毛茸,毛茸多分布在叶脉、叶缘,叶尖微凹或突起。结论 微性状鉴别方法简便,可以区别香茶菜属不同植物。     

大鼠脑液压冲击伤后细胞色素C表达的实验研究

目的　为法医学上闭合性颅脑损伤的早期诊断和损伤时间推断提供依据。　方法　建立大鼠脑液压冲击模型。用免疫组化与图像分析技术分别检测伤后不同时间大鼠脑皮质、海马等部位细胞色素C(CytochromeC ,CytC)的表达。　结果　对照组大鼠脑内CytC有微量表达 ,伤后 15分钟表达开始增强 ,伤后 3小时达高峰 ,1天后开始减弱 ,7天后基本恢复正常。　结论　CytC表达的规律性可望为闭合性颅脑损伤的早期诊断及损伤时间推断提供依据。     

公安管理信息系统的设计与实现

信用证在国际贸易货款结算过程中的若干法律适用问题研究——兼评UCP500的适用

信用证在国际贸易货款结算中是最常用的一种方式,它以银行信用取代商业信用,大大降低了国际贸易中的风险。然而,由于在信用证业务中,银行只负责审查单据,而不考虑货物的实际情况,即只要“单单相符,单证相符”就应付款。因而,出现了诸如非单据性条款、单证不符、信用证修改等亟待解决的问题。     

毛泽东与1961年全党调查研究述论

庐山会议后，以“共产风”为主的“五风”愈演愈烈，给国民经济带来严重困难。在毛泽东看来，信息渠道不畅，全党认识不统一，实事求是的思想作风没有得到大力倡导，是导致国民经济困难的深层原因。他认为全党只有大兴调查研究之风才能解决这些问题。在他的倡导下，1961年全党很快掀起调查研究的热潮。此次调查研究给我们留下许多宝贵的经验。做好调查研究工作，必须充分发扬党内外民主，切实贯彻群众路线，抓住调查研究的重点。

Corrupt reciprocity - Experimental evidence on a men's game

Why are women regarded to be more resistant towards corruption? We address this question by letting students allotted the role of public servants receive a bribe and choose between reporting (whistleblowing), opportunism and reciprocity (delivery of a contract to the briber). Those acting as businesspersons choose whether or not to publicize at the end of the game. Male businesspersons more often depart from maximizing payoffs and allocate resources to punishing opportunistic public servants. Instead of acting opportunistically, some public servants tend to reciprocate or report. We find that female public servants are less inclined to reciprocate. Their resistance towards corruption is found to relate less to a willingness to report. Survey data from international households shows that men are more confident that bribes will be reciprocated, supporting our results.
