Protons are atoms that carry a positive charge. Just as x-rays are used to treat both benign and malignant tumors, a beam of protons can be used to radiate tumors in the same way. There is essentially no biological difference between x-ray and protons, except that protons release most of their energy when they hit the tumor and deliver no exit dose beyond the tumor boundary. Therefore, the dose of radiation conforms to the tumor better and there is less damage to healthy tissue. As a result, the treating physician (a radiation oncologist) can give an even greater dose to the tumor while minimizing unwanted side effects. This is especially important when treating children, because it reduces radiation to growing and developing tissues.

GMO - Genetically modified organism (GMO) is Genetic material of an organism is altered with the help of genetic engineering techniques generally known as recombinant DNA technology. DNA molecules from one source is combined with the DNA of other in vitro into one molecule to create a new gene. The recombinant DNA is then transferred into an organism causing the expression of modified or novel traits. The product is also known as an Genetically Engineered Organism or GEO.
Examples Transgenic animals (mice, fish), transgenic plants (BT Cotton, Flavour Savour Tomato), or various microbes (fungi and bacteria) . The production and use of GMOs are ivolved in biology or medicine, for the production of pharmaceuticals and industrial enzymes, and for direct, and often controversial, applications aimed at improving human health (e.g., gene therapy) or agriculture (e.g., golden rice). For example, a gene from a jellyfish, encoding a fluorescent protein called GFP, can be physically linked and thus co-expressed with mammalian genes to identify the location of the protein encoded by the GFP-tagged gene in the mammalian cell. The indispensable use of GMO is in many areas of research, such as to study the mechanisms of human and other diseases .

For ex vivo gene transfer of RA-SFs, retroviral vectors have been used . This is because retroviruses are easy to produce and, through integration of their genetic information into the host genome, they can achieve
longlasting expression of the transgene.
