The lessons learnt from the treatment of previous radiation accidents using either bone marrow transplantation or growth factor therapy suggest that it is of importance to investigate new therapeutic regimens. Ex vivo expansion of haematopoietic stem cells, precursors and differentiated cells is a new approach of growth factor therapy which may be of interest for the treatment of patients with ...

In the present work, we aim to investigate ability of zirconium-based MOF-type compound UiO-66-NH2, immobilize molecular gaseous iodine under conditions analogous those encountered in an operating Filtered Containment Venting System (FCVS) line. Typically, UiO-66-NH2 particles were exposed 131I (beta and gamma emitters) submitted air/steam at 120 °C, irradiation (1.9 kGy h-1). parallel this exp...

objective: the purpose of this study was to investigate the incidence, type, location, and risk factors of accidental fetal lacerations during caesarean delivery. material and methods: total deliveries, caesarean deliveries, and neonatal records for documented accidental fetal lacerations were reviewed retrospectively in four university hospital. thegestational age, the presenting part of the f...

Abstract Samples of copper-modified bioactive borate glasses were synthesized and their radiation shielding properties including gamma-ray neutron investigated. Further, the glasses’ mass attenuation coefficients measured with a NaI(Tl) detector while parameters estimated using Phy-X/PSD program. Free-radical densities via electron spin resonance to estimate absorbed doses during accidental irr...

Total body irradiation (TBI) or partial body irradiation is a distinct risk of accidental, wartime, or terrorist events. Total body irradiation is also used as conditioning therapy before hematopoietic stem cell transplantation. This therapy can result in injury to multiple tissues and might result in death as a result of multiorgan failure. The hypothalamic-pituitary-adrenal (HPA) axis could p...

In an attempt to elucidate mechanisms underlying the irradiation-induced decrease in regional cerebral blood flow (rCBF) in primates, hippocampal and hypothalamic blood flows of rhesus monkeys were measured by hydrogen clearance, before and after exposure to 100 Gy, whole body, gamma irradiation. Systemic blood pressures were monitored simultaneously. Compared to control animals, the irradiated...
