Professor lau concluded that osteoporosis is a major and neglected disorder in chinese men . we recommend all men who are 65 years and older , and who have one of the above characteristics to have their bone density measured by dual x - ray densitometry . 刘教授指出，骨质疏松在华裔男性是一个严重但被忽略的疾病，我们建议六十五岁以上的男士如果有上述其中一个问题，就应该进行双能量x光骨质密度素描。
He is , however , a member of the prestigious institute of medicine and is renowned for refining an imaging technique called computed tomographic ( ct ) densitometry to help physicians discriminate between noncancerous nodules in the lung and lung cancers , based on the calcium content of the tumors 不过他是声誉卓著的国家医学研究院的成员，且因为改良电脑断层扫描密度测量仪而出名，这种影像技术可以帮助医生，根据肺部肿瘤细胞的钙质含量，来区分是良性肿瘤还是肺癌。
A significant level of 3galt - 1 transcript was present in the brains of 18 - day - old mouse embryo , newborn and 1 - week - old mice . hereafter , its level decreased markedly . densitometry analysis indicated that the p3galt - l band was 10 - fold more intensive in the 1 - week - old mouse brain than that in the 12 - week - old , indicating that 3galt - l mrna was expressed at a developmentally regulated way 我们用northernblot的分析方法发现在18天龄胚鼠、新生鼠和1周龄鼠的脑组织中3galt - 1表达很高，随着发育进程，它的表达水平明显降低：灰度扫描定量分析表明1周龄鼠脑中3galt - 1的表达量大约是12周龄鼠脑表达水平的10倍，这说明3galt - 1的表达是受发育调控的。
