Dec. 2, 2004 — Magnetic resonance imaging-guided focused ultrasound is effective for treatment of uterine leiomyomata, according to early results of a study published in the December issue of the American Journal of Roentgenology. The ExAblate 2000 device used in this study was recently approved by the U.S. Food and Drug Administration.

Dec。 2， 2004 -一项发表於12月号美国放射学期刊上的试验早期结果显示，核磁共振造影导引的聚焦超音波对於治疗子宫平滑肌瘤是项有效的治疗选择；这项试验中所使用的ExAblate 2000装置最近已经获得美国食品药物管理局的核准上市。

Like roentgenology, psychoanalysis is a fascinating, but relatively new, means of illuminating the person. But few of us are prepared to substitute an X-ray of Grandfather's head for the portrait that hangs in the parlor.

和放射学一样，精神分析也是一种用来透视人的神奇的新手段，但毕竟很少有人愿意把挂在客厅里的祖父画像换成一张呈现他头颅结构的X光片。

At Hopkins he conducted research on infrared radiation with funds provided by the Office of Naval Research. During his sabbatical year, at Michigan State University in 1954–55, he gained access to a large computer and realized it offered the perfect way to construct a better model of radiative transfer. In 1955 Plass moved out of academics, serving for a year as a staff scientist with Lockheed Aircraft Corporation. He then joined the advanced research staff of the Aeronutronic division of the Ford Motor Company.

他在霍普金斯大学进行了红外放射的研究，经费由美国海军研究局提供。1954至1955年他在密歇根州立大学休了一学年的假，期间接触到了大型计算机，并意识到这是改进辐射传热模型的理想工具。1955年，普拉斯离开了大学，在洛克希德飞机公司做了一年的科研人员，随后作为高级研究员加入了福特汽车公司的Aeronutronic部门。

Levels of Giα protein in sarcolemma were measured by Western blot analysis,and adenyl cyclase activities were determined by radioimmunoassay.

采用Western 杂交法和放射免疫法分别测定大鼠心肌Giα及腺苷酸环化酶的活性。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.
