Acute radiation syndrome affects military personnel and civilians following the uncontrolled dispersal of radiation, such as that caused by detonation of nuclear devices and inappropriate medical treatments. Therefore, there is a growing need for medical interventions that facilitate the improved recovery of victims and patients. One promising approach may be cell therapy, which, when appropria...

Elbow injuries are commonly seen in accident departments. Patients with possible bony injuries to the elbow were assessed to see if inability to fully extend the elbow was a good indicator of bony injury and hence the need for X-ray. The sensitivity of this test was 90.7% (95% confidence limits 80.7-100.7) and the specificity 69.5% (95% confidence limits 60.3-78.7). Use of this simple test woul...

On 13 September 1987, a radiation accident occurred in the city of Goiânia in Central Brazil. Approximately 250 people were exposed to a 137Cs source from an abandoned radiotherapy unit. At least 14 patients showed some degree of bone marrow depression, and eight developed the classical signs and symptoms of acute radiation syndrome (ARS). Twenty-eight people presented local radiation injuries ...

OBJECTIVE Free radicals generated by ionizing radiation attack various cellular components such as lipids. The lung is a very radiosensitive organ and its damage is a doselimiting factor in radiotherapy treatments. Melatonin (MLT), the major product of the pineal gland acts as a radioprotective agent. This study aims to investigate the radioprotective effects of MLT on malondialdehyde (MDA) lev...

A new generation of arc welder has recently become widely available at a price which is within reach of most amateurs and part-time mechanics, known as the MIG welder (metal-arc inert gas welder). In MIG welding the arc is ensheathed in a stream of inert gas which prevents the molten metal from oxidising. The stream of gas changes the character of the emitted radiation, and it is possible that ...

Interventional radiology (fluoroscopically-guided) techniques are being used by an increasing number of clinicians not adequately trained in radiation safety or radiobiology. Many of these interventionists are not aware of the potential for injury from these procedures or the simple methods for decreasing their incidence. Many patients are not being counselled on the radiation risks, nor follow...

Glioblastoma is most common and most aggressive cancer of brain. for treatment surgery is first selection and radiation therapy then chemotherapy. The median survival of Patients with GBM is less than a year after diagnosis. Glioblastoma is basically resistant to common cancer treatments. today to improve the response of patients to treatment, a number of strategies such as the use of radiation...

a. This chapter will cover basic biophysical and biological effects of ionizing radiation in order to form a foundation for understanding the clinical aspects of radiation injury discussed in Section IV of Chapter 6. This extended discussion of radiation does not imply that nuclear radiation will be the most important cause of casualties after a nuclear explosion. Blast and thermal injuries in ...

In spite of the fact that radiotherapy is a common and effective tool for cancer treatment; the radio sensitivity of normal tissues adjacent to the tumor which are unavoidably exposed to radiation limits therapeutic gain. For the sake of improvement in radiation therapy, radiobiology- the study of the action of ionizing radiation on living things- plays a crucial role through explaining observe...
