放射治疗的

Our data show that the circadian clock and haem biosynthesis are reciprocally regulated and suggest that porphyrin-containing molecules are potential targets for therapy of circadian disorders.

这说明，卟啉衍生物（B12含有卟啉）是如癌症等生物节律失调疾病的潜在治疗药物，而且通过细胞周期调节物质与生物钟之间的联系，还可用在接受化学疗法和放射疗法的患者身上。

However, this method requires precise immobilization and repositioning of the patient.

因此，精确的定位系统便在决定能否执行精确的放射治疗上占相当重要的因素。

This model can be used to study the pathogenesis of radiation-induced cognitive changes.

这种动物模型可用于放射治疗诱发的认知功能障碍的病理机制的研究。

Objective:To discuss that using couch-height as the parameter of vertical position in the radiotherapy reduce the vertical deviation from the central point, which is caused by the change of the patient's body, fixation and so on.

目的：探讨以床面高度作为垂直摆位参数，在放射治疗中可以减少因患者身体变化和固定装置等因素的影响引起的中心点的垂直位移偏差。

The results emphasize the importance of ophthalmologic examination of retinoblastoma survivors who have undergone radiotherapy.

研究结果强调了行放射疗法治疗的视网膜母细胞瘤的幸存者中眼科检查的重要性。

This review on organobismuth chemistry is carried out as the following four aspects:(1) the molecular structure characteristics and synthesis of new organobismuth compounds;(2) as reagents for cross-coupling, oxidation, arylation, and other reactions;(3) as catalysts for organic synthesis;(4) as medicines for the treatment of ulcers, anti-tumor and radio-therapy, etc.

本文回顾了近10多年来有机铋化学的研究状况，主要从以下4个方面进行综述：(1)新型有机铋化合物的合成途径与结构特征；(2)有机铋化合物作为交联偶合、氧化、芳基化和其它反应的试剂；(3)作为催化剂；(4)作为生物医药用于溃疡、肿瘤和放射治疗等。

Surgical management of such lesions should be directed by clinical and radiological features as well as patient expectations.

外科手术治疗的这样的病变取决于病变临床、放射学检查的特点和患者期望。

It is also an important contribution to the discussion of the optimal treatment of pituitary adenomas worldwide.

在利用传统的体外放射治疗来处理腺垂体疾病的每一个病例必须进行关键的风险-收益分析。

How it works: Instead of hilling a tumor with large beams of radiation from only a few directions, as is done with conventional radiotherapy, PEACOCK calculates precise angles and dosed using a computer and CT scan.

工作原理传统的放射治疗是从几个方向用大量的放射性光束来攻击肿瘤，而孔雀'则是用计算机和CT扫描仪计算出肿瘤的精确角度和辐射吸收剂量。

Modern radiotherapy requires new approaches to dosimetry. The dosimeters must be able to assess the dose not only in a point but also in complex three-dimensional objects.

放射治疗已经发展到3D适形和调强阶段，使得剂量不但具有3D空间分布而且随时间变化，传统的3D水箱的静态测量方式已经不能满足剂量验证的要求。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
