Zhongguo shiyan zhenduanxue, 2007 目的研究一氧化氮合酶抑制剂（L-NAME）对横断的大鼠坐骨神经再生的促进作用。方法取SD大鼠40只随机平均分成4组。剪断右侧坐骨神经总干,两断端的神经外膜缝合。实验组给以L-NAME,剂量为10 mg/kg体重,用生理盐水（SAL）稀释至100μl。对照组给药方式与第一组相同,给以D-NAME。将获得的各组动物实验侧MCV及PR分别与对照侧数据作比率,获得的比值在实验组和对照组间进行t检验。结果实验组明显优于对照组。结论L-NAME对周围神经损伤再生有明显加强作用。

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

顺铂联合血管内皮抑制素对体外培养的U251人胶质瘤细胞生长的影响
Zhongguo shiyan zhenduanxue, 2010 目的以体外培养的U251人胶质瘤细胞作为模型,观察顺铂联合血管内皮抑制素对肿瘤细胞生长的影响。方法采用不同浓度的顺铂和血管内皮抑制素及顺铂与血管内皮抑制素的组合作用于体外培养的U251人胶质瘤细胞,以MTT比色法检测其对肿瘤细胞生长的影响。结果不同浓度的顺铂与血管内皮抑制素联合应用对体外培养的U251人胶质瘤细胞生长具有非常明显的协同抑制作用,强于单独使用顺铂或血管内皮抑制素组。结论顺铂联合血管内皮抑制素对体外培养的U251人胶质瘤细胞具有协同杀伤作用。

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Jianzhu Gangjiegou Jinzhan, 2016 当结构的高宽比较大时,在设防与罕遇地震作用下高烈度区的超高层结构的核心筒剪力墙可能承受倾覆力矩引起的巨大拉力,垂直于地震作用方向的核心筒翼墙受力状态接近于轴心受拉。由于混凝土抗拉强度较小,常采用钢板组合剪力墙来抵抗较大的墙肢拉力。采用非线性有限元法,对钢板组合剪力墙在轴心受拉作用下的开裂荷载、刚度变化、滞回性能与受拉承载力进行了较为全面的研究,表明混凝土对构件的轴拉承载力与刚度具有一定贡献。给出了钢板组合剪力墙在轴心受拉状态下最大裂缝宽度的计算方法,分析了墙体含钢率以及型钢、钢筋布置方式对裂缝宽度的影响。

Dianci bileiqi, 2013 为了研究限压型低压电涌保护器级间能量配合的保护方式,参考IEEE工作组提出的MOV冲击等效电路模型,利用EMTP电磁暂态仿真软件来模拟在8/20μs、10/350μs两种冲击电流波作用下两级SPD最有效的配合保护方式。仿真结果得出在8/20μs冲击电流波作用下采用高-低配合的方式,而在10/350μs冲击电流波作用下采用低-高配合的方式是最为合理的。为敏感电子设备的防雷保护提供了参考依据。

ABCA12 Frameshift Deletion in Domestic Cats With Ichthyosis Fetalis
Veterinary Dermatology, EarlyView.ABSTRACT Background Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears.
