The skin, and in particular the basal layer of the epidermis, is the main target for damage to humans by solar radiation. The physical manifestations of this injury range from acute sunburn to long term effects such as skin ageing and basal and squamous cell carcinomas. Although solar ...
Your cell phone emits and receives signals. There is an electro magnetic field around each cell phone, which affects you. When its field overlaps your body, it causes irreversible damage to your body cells and brain cells. Cell phone damage can affect your memory, endocrine secretions, sexual ...
but it can also cause considerable and even permanent injury to the brain. Now, through preclinical experiments conducted in rats, Memorial Sloan Kettering Cancer Center researchers have developed a method to turn human stem cells into cells that are instructed to repair damage in the brain....
Why Radiation Damage is More Effective than Endogenous Damage at Killing Cells As illustrated in Figure 1, the radiation track deposits energy in the biomolecules of the cell during its passage. The pattern of these discrete energy depositions during passage of the ionising track causes chemical mod...
Protection of the hematopoietic system from radiation damage, and/or mitigation of hematopoietic injury are the two major strategies for developing medical countermeasure agents (MCM) to combat radiation-induced lethality. In the present study, we invest

cells are highly sensitive to radiation. However, other internal organs (liver, kidney, lung, and heart) are weakly sensitive to radiation damage caused by receiving local radiotherapy. Radioactive nuclides orradiocontrast mediaused in medical imaging/treatment can cause radiation damage to internal ...

We have examined whether there are differences in cytotoxicity between partially ultraviolet-irradiated cells and uniformly irradiated cells after equal amounts of DNA damage were induced in the cell nuclei. We first determined DNA damage formation in normal human fibroblasts using an enzyme-linked ...
is currently conducting a phase I/II clinical trial in lung cancer patients consisting of twice-weekly swallowed MnSOD for protection of the esophagus from chemoradiotherapy damage, these results suggest that minicircle DNA containing the human MnSOD transgene confers undiminished radioprotection to cells...
