Trinh T Do et al.
In DNA, guanine bases are the sites from which electrons are most easily removed. As a result of hole migration to this stable location on guanine, guanyl radicals are major intermediates in DNA damage produced by the direct effect of ioniz...
Kinetic behavior of the reaction between hydroxyl radical and the SV40 minichromosome [0.03%]

A Ly
Aqueous solutions containing the minichromosomal form of the virus SV40 and the radical scavenger DMSO were subjected to gamma-irradiation, and the resulting formation of single strand breaks (SSB) was quantified. Under the irradiation cond...
Photo-induced regeneration of hormones by electron transfer processes: Potential biological and medical consequences [0.03%]
通过电子转移过程的光诱导激素再生：潜在的生物学和医学后果
Nikola Getoff,Johannes Hartmann,Heike Schittl et al.
Nikola Getoff et al.
Based on the previous results concerning electron transfer processes in biological substances, it was of interest to investigate if hormone transients resulting by e.g. electron emission can be regenerated.The presented results prove for th...

Michael Dingfelder et al.
Electron emission spectra from thin metal foils with thin layers of water frozen on them (amorphous solid water) after fast proton impact have been measured and have been simulated in liquid water using the event-by-event track structure co...
Cryoradiolytic reduction of heme proteins: Maximizing dose dependent yield [0.03%]
用于减少血红蛋白蛋白质的冷冻辐射：最大化剂量依赖性产量
