前列腺特异抗原移行区密度在PSA灰色区域前列腺癌早期诊断中的作用

open access: yesZhongguo shiyan zhenduanxue, 2007
目的探讨前列腺特异抗原移行区密度(PSAT)在前列腺癌早期诊断中的作用。方法在血清PSA>4.0 ng/ml,并接受前列腺活检的144例受检者为研究对象,根椐病理学诊断分为前列腺癌组(PCa组)、良性前列腺增生组(BPH组);血清PSA含量应用瑞典CanAG公司试剂盒;经直肠超声测量前列腺癌体积和移行区体积,分别计算前列腺特异抗原密度(PASD)和PSAT。应用SPSS(10.0)软件进行统计学分析。结果(1)受检者的前列腺移行区体积与前列腺总体积呈明显正相关(r=0.78,P0.05 ...

TRANSIENT STABILITY ANALYSIS ON A MULTI-MACHINE SYSTEM IN PSAT

open access: yesInternational Journal of Research in Engineering and Technology, 2015
Modern power system are subject to large disturbances such as three phase short circuit faults. When a fault occurs on a system the generators rotor angle becomes unstable and thus it losses synchronism with the system and it becomes unstable. Thus transient stability analysis can be performed on a system in order to understand the generators ...

Concurrent Validity of the PASAT and Adjusting-PSAT in Patients with Multiple Sclerosis [PDF]

open access: yesInternational Journal of MS Care, 2004
Impaired information processing speed (IPS) is common in multiple sclerosis (MS). Performance on the Paced Auditory Serial Addition Test (PSAT)—the measure recommended by the United States National MS Society Task Force to track changes in IPS—does not indicate the precise speed at which IPS breaks down.
