But at one time, handedness ( twist direction of the shell) was equally distributed within some snail species that have become predominantly dextral or, in a few species, predominantly sinistral. 但是曾经,许多蜗牛品种的手性(壳的螺旋方向)分布是均等的,后来都变成了右旋为主,只有少数一些品种是左旋为主的。
Imaging permitted the handedness or chirality of each flattened nanostructure to be determined, based on the height differences observed at the overlapping areas. 影像允许每个惯用手或手性纳米结构扁平待定的基础上,高度差在重叠区域观察。

OBJECTIVE: To analyze the relationship of handedness with language-dominant hemisphere of patients with cerebral infarction whose native language is Chinese. 目的:分析母语为汉语的脑卒中患者利手与语言优势半球的关系。
The hereditary mode of handedness or folding leg was likely the dominant heredity of single gene of autosome, and the right type of them was the dominant character. 利手和叠腿很可能均为常染色体单基因遗传,利手右型和叠腿右型分别为显性性状;
More or less, environmental factors affected the phenotypes of the 6 characters, and there was less environmental influence on the traits of tongue moving types and clasping hand than handedness and folding leg. 环境因素对此6项特征均存在不同程度的影响,其中对舌运动类型特征和扣手的影响较小,对利手和叠腿的影响相对较大。
The Effect of Handedness on Tracking Performance 利手因素对追踪操作的影响
METHODS: A patient with unilateral acute subcortical infarction and a normal subject of right handedness, who were hospitalized in the General Hospital of Daqing Oil Field in June 2004, received fMRI with passive single finger exercise task. 方法:应用被动单指运动任务,对2004年6月大庆油田总医院住院的1名急性单侧皮质下梗死患者和1名正常右利手被试进行功能性磁共振成像研究。

Analysis of the handedness in children with autism 自闭症儿童利手调查分析
MAIN OUTCOME MEASURES: Relationship of handedness with language-dominant hemisphere of patients with cerebral infarction. 主要观察指标:脑卒中患者利手与语言优势半球的关系。
The reason may be that handedness was so proficient that needed less brain resources. 这可能与用利手作出反应时熟练程度更高,相对消耗的脑资源更少,可能有利于右半球优势的出现。
Methods: Auditory ERP, cognitive capacity screening examination ( CCSE) and mini-mental state examination ( MMSE) were studied separately in 32 patients with TIA and 30 normal subjects matched with age, sex, handedness and education. 方法:用听觉Oddbal刺激序列ERP、认知能力筛选试验(CCSE)和简易智力状态试验(MMSE)检测32例TIA病人和30例年龄、性别、利手和教育程度相匹配的正常人。
The result indicates that there is no influence of handedness on tracking performance and key press action of a speed perception task. 结果表明利手因素对手动追踪操作和对速度判断的按键反应操作没有影响。
There was obvious correlation between handedness and hand clasping, but no relation between handedness and arm folding, arm folding and arm folding. 惯用手与扣手间存在明显的相互关系,扣手与交叉臂以及惯用手与交叉臂之间则无关。
