Background The association between advanced interatrial block (aIAB) and atrial fibrillation (AF) is known as "Bayes' Syndrome". There is little information on the prognostic role that new speckle tracking echocardiographic (STE) imaging techniques could play in it. Purpose We have examined the rel...
从中国山东威海海域以及新西兰部分海域等全球裙带菜(UndariaPinnatifida)主要产地采收裙带菜样品,对样品中的粗多糖和重金属含量分别进行测定,分析和比较了不同产地裙带菜中常规理化成分含量的差异.此外,对提取的粗多糖进行了衰减全反射(ATR)红外光谱检测,测得硫酸根特征基团,明确了该粗多糖中主要成分为硫酸脂多糖,且硫酸根...
A tripod-type constant velocity universal joint in which rollers roll straight in parallel to track grooves of an outer joint member. In the joint, contact surface pressure of rolling bodies placed between the rollers and leg shafts is reduced. The peripheral surface of each leg shaft is formed...
