【medical-news】强放射源对癌症影响的进一步研究
Plans to construct Europe's most intense terahertz (THz) radiation source to further development of cancer research are underway at the University of Liverpool
Physicists will construct an ultra-high intensity THz beamline and attempt to destroy skin cancer cells specially grown in a new tissue culture facility. The experiments will help scientists understand how to use this technology in future treatments for the disease in humans.
The THz beamline, funded by the Northwest Regional Development Agency (NWDA) through its North West Science Fund, will be developed using the prototype Fourth Generation Light Source (4GLS) being constructed at CCLRC Daresbury Laboratory, which will be used to develop light sources used in X-ray technology, laser studies and radiation sources.
Physicist, Professor Peter Weightman, said: "The prototype 4GLS facility is based on an Energy Recovery Linear accelerator. The energy produced by firing electrons around this accelerator will partly be used to power the THz beamline, which will link up to a tissue culture facility developed with scientists at the University of Nottingham.
"The culture facility will be used to grow skin cancer cells and the THz radiation will target the source of the cancer. THz is absorbed by water and cancer cells retain water, so the THz radiation should be consumed by the cell and kill it off at the source."
Terahertz radiation has also been used in the detection of concealed weapons, explosives and drugs as it has the ability to penetrate a variety of materials such as clothing, paper, cardboard, wood, masonry, plastics and ceramics. THz can also pick up on vibrations and rotations of molecules and has been useful in identifying molecules floating in space.
The team at Liverpool hope to develop these applications using the most powerful source of broad band terahertz available in Europe - a thousand times more powerful than current laboratory sources.
This will be the first time THz technology has been used on cancer cells and it will also be developed to characterise genetic material. THz has the capability of identifying mutations in DNA, which could help medics identify pharmaceutical therapies that will be compatible with individual patients' DNA information.
Dr George Baxter, NWDA Director of Science and Innovation, said: "The NWDA is delighted to support this innovative project that will help develop new technology for the treatment of cancer. Investment in this project forms part of the NWDA's commitment to build and sustain a knowledge based economy for England's North West." 认领这个

强辐射源对癌症影响的进一步研究

为了癌症研究的长远发展而进行的构建欧洲最强辐射源的计划正在利物浦大学实施。

物理学家将构建超高 强度的光束线，并试图用它摧毁皮肤癌细胞尤其是在新组织培养仪中生长的皮肤癌细胞。这项试验将帮助科学家理解如何运用此项技术治疗人类的这种疾病。

这项计划是由西北发展局的西北科研基金资助的，将应用由CCLRC Daresbury实验室开发的标准第四代光源来进行发展。这个第四代光源是将用于X线技术，激光以及辐射源的光源的。
Physicist, Professor Peter Weightman, said: "The prototype 4GLS facility is based on an Energy Recovery Linear accelerator. The energy produced by firing electrons around this accelerator will partly be used to power the THz beamline, which will link up to a tissue culture facility developed with scientists at the University of Nottingham.
物理学家Peter Weightman教授说：“标准第四代光源仪是基于能量恢复直线加速器的设备。由在加速器中发射电子产生的能量将部分用于为超强光束线供能。而这超强光束线则被连接到由科学家在诺丁汉大学研发的组织培养仪上。”
"The culture facility will be used to grow skin cancer cells and the THz radiation will target the source of the cancer. THz is absorbed by water and cancer cells retain water, so the THz radiation should be consumed by the cell and kill it off at the source."
该培养仪将被用于培养皮肤癌细胞并且超强的辐射将靶向癌症源。辐射被水吸收，癌细胞吸收水，这样超强辐射就被细胞吸收并将其源头一并杀死。
