门子的“说”与“不说”

门子自然是《红楼梦》中的那个门子。门子的“说”，自然是指贾雨村在断“薛蟠打死冯渊”一案时，他对贾雨村所说的那番话，致使贾雨村“一改初衷”，胡乱地判了“葫芦案”。而门子的“不说”，则是指他保持沉默，对一切装聋作哑，视而不见。     

Developmental Associations Between Adolescent Change in Depressive Symptoms and Menstrual-Cycle-Phase-Specific Negative Affect During Early Adulthood

The causal factors associated with increases in depressive symptoms among adolescent girls remain an area of theoretical debate, and the limited research considering a hormonal influence has provided mixed results. The goal of the present study was to test a set of longitudinal associations, that, if found, would provide support for a hormonal contribution to these changes. Specifically, this study tested the hypotheses that changes in depressive symptoms among adolescent girls would be associated with phase-specific symptoms of the menstrual cycle during early adulthood; that these associations would differ across three phases of the menstrual cycle; and that the pattern of associations would differ for changes in depressive symptoms during early- and late-adolescence. The sample consisted of 47 women with longitudinal data from 12 to 21 years old (approximately 91% European Canadian, 4% Middle Eastern Canadian, 2% Haitian Canadian, and 2% Asian Canadian). Consistent with expectations, results showed that early-adolescent increases in depressive symptoms were negatively associated with menstrual-phase negative affect, and positively associated with mid-cycle negative affect, but not associated with premenstrual negative affect; whereas late-adolescent change in depressive symptoms was only associated with depressive symptoms at 20-21 years. Thus, early-adolescent changes in depressive symptoms are longitudinally associated with later mood change across the menstrual cycle, suggesting a common underlying cause, which is hypothesized to be hormonal. Moreover, results suggest that, with respect to variables that are involved in affective development, important differences exist between early- and late-adolescence. The discussion considers menstrual-cycle-related symptoms (e.g., dysmenorrhea) during adolescence, and the need to study their effects on development. It is suggested that focused intervention and prevention efforts may be indicated to interrupt negative developmental outcomes.     

TD-RAPD技术用于罂粟品种鉴定初探

目的探索TD-RAPD技术用于罂粟品种鉴定的可行性。方法采用改良CTAB法从罂粟叶片中提取DNA;TD-RAPD技术对种植于云南西双版纳地区的1个罂粟样品进行扩增分析。结果建立了罂粟DNA提取方法,从10个随机引物中筛选出6个引物用于罂粟TD-RAPD分析。结论TD-RAPD技术可用于罂粟DNA的分子标记,为罂粟DNA数据库建立提供技术方法,最终从DNA分子水平上追溯罂粟植物毒源。     

Hair as a specimen to document tetramethylene disulfotetramine exposure

Tetramethylene disulfotetramine (tetramine) is a rodenticide that has been banned for many years in China. Since 2005, inhabitants of a village in the Henan Province have been suffering from grand mal seizures. To investigate the possibility of tetramine as the cause, we developed a method to determine tetramine in human hair. Sample preparation involved external decontamination, frozen pulverization, and ultrasonication in 2 mL ethyl acetate in the presence of cocaine-d3 as an internal standard. The method exhibited good linearity; calibration curve was linear over a range of 0.1-20 ng/mg hair. The limit of detection for the assay was 0.05 ng/mg hair. Except for one subject (No. 4), all head and pubic hair samples were positive for tetramine. The concentrations of tetramine in pubic hair were significantly higher than those in the same subjects' head hair samples. Because of a long retention in body, segmental head hair analysis cannot provide an accurate exposure history of tetramine in the body.

法律移植问题综述

我国历史悠久,文化底蕴深厚,有着具有自己民族特色的法律传统。同时,在全球化浪潮的冲击下,移植和借鉴他国法律成为我国法律建设的重要途径之一。但由于各国的法律文化土壤不同,移植法律的冲击力亦会有所不同。法律移植这一理论问题已被学界关注多年,相关学术成果也可谓汗牛充栋。从数据显示可以看出,法律移植与法律全球化联系甚密,几乎与之同步,2001年方有大量的相关论文被发表,2001年之前研究亦有只是成果鲜少。因此本文所谈之法律移植是全球化背景下的法律移植。
