Prenatal Exposure to Airborne Particulate Matter on the Development of Heart in Rat Fetus [PDF]
大气颗粒物(ParticulateMatter,PM)是指悬浮在大气中的固体、液体颗粒物的总称。不同来源的颗粒物形成条件不同,其粒径分布、化学组成也不同。目前国际公认的对人类健康危害较大且研究较多的大气颗粒污染物是PM2.5(FineParticulateMatter)和PM10(InhalableParticulateMatter)[1]。越来越多的证据表明,PM严重威胁着人体的健康,更对孕妇及胎儿的发育产生不良影响,导致出生缺陷儿增多,使出生人口质量下降,增加死亡率。因此 ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Complete androgen insensitivity syndrome, a pedigree gene mutation analysis [PDF]
研究背景 雄激素不敏感综合征(AndrogenInsensitivitySyndrome,AIS),是一种常见的男性假两性畸形。是伴X连锁隐性遗传病。患者染色体核型为46,XY,但其X染色体上的雄激素受体(Androgenreceptor,AR)基因存在缺陷,可致雄激素靶器官上的AR出现缺陷,体内的雄激素不能发挥相应的作用而出现相应的临床症状。此疾病可对患者的生殖能力造成不同程度的影响,还可能引发与性发育异常相关的性心理、性行为的异常,并可能给社会和患者家庭造成难以挽回的损失 ...

Studies of Hyperaccumulation Mechanism of Eucalyptus grandis×E. urophylla to Manganese and Arabidopsis Transporter’s Functions on Metal Transportation and Signaling [PDF]
重金属污染已经成为世界性问题,严重威胁人体健康,已引起广泛的关注。植物修复技术作为一种经济、环境友好的土壤污染治理途径,也引起越来越多人的兴趣。只有寻找到更多合适的超富集植物,并且深入研究重金属的耐受和吸收、转运途径,才能有效地控制重金属对作物的污染或者更好发挥超富集植物的修复潜能。 本论文通过矿区筛选,发现了新的诱导型锰超富集植物-巨尾桉。该植物可以在叶片富集大量锰元素。通过实验室水培和ICP-MS联用技术研究其对锰的耐受性、在各组织中的分异 ...

The development of early attachment: An observation study on an infant throughout the first year [PDF]
为深入探讨儿童依恋发生、发展的微观机制,由一名专业的发展心理学研究者采用自然观察法,在一年内(2006.4.14-2007.4.14)每天对一名健康女婴Sunshine(化名)进行客观记录或登记。结果显示,Sunshine的依恋经历了一个由“子宫依恋”(0-1.5个月左右最明显)到“类子宫依恋”(1.5-6个月左右最典型),再到“社会子宫依恋”(6个月以后明显)的发展过程,其中“类子宫依恋”阶段又分为泛化的“类子宫依恋”阶段(1.5-2.5个月左右最典型)与分化的“类子宫依恋”阶段(约2.5 ...
