Accidental hypothermia was studied in 11 patients, five of whom died. This condition occurs spontaneously, usually in a cold environment, and should be suspected in the comatose hypotensive patient. It is easily missed because regular clinical thermometers do not record extremely low body temperatures. It is distinguished from other forms of hypothermia by the very low body temperature and by t...

BACKGROUND Radiation-induced injury after accidental or therapeutic total body exposure to ionizing radiation has serious pathophysiological consequences, and currently no effective therapy exists. This study was designed to investigate whether transplantation of allogeneic murine compact bone derived-mesenchymal stem cells (CB-MSCs) could improve the survival of mice exposed to lethal dosage t...

The impact of ionizing radiation on developing organisms has been widely studied for risk assessment purposes. Even though efforts have been made to decrease received doses to as low as reasonably achievable, the possibility of accidental exposure has to be considered as well. Mammalian gestation is usually divided into three periods. Radiation ex...

Damage to normal human brain cells from exposure to ionizing radiation may occur during the course of radiotherapy or from accidental exposure. Delayed effects may complicate the immediate effects resulting in neurodegeneration and cognitive decline. We examined cellular and molecular changes associated with exposure of neural stem/progenitor cells (NSPs) to (137)Cs γ-ray doses in the range of ...
