The Chemistry and Toxicology of Depleted Uranium
Natural uranium is comprised of three radioactive isotopes: 238 U, 235 U, and 234 U. Depleted uranium (DU) is a byproduct of the processes for the enrichment of the naturally occurring 235 U isotope. The world wide stock pile contains some 11⁄2 million tons of depleted uranium. Some of it has been used to dilute weapons grade uranium (~90% 235 U) down to reactor grade uranium (~5% 235 U), and s...
متن کاملA review of Novichok Toxicology
Introduction: Novichoks are considered as the fourth generation of chemical weapons and nerve agents (NA) category. NAs were produced and developed during the Cold War in the (former) Soviet :union:. Due to the confidentiality of the manufacturing process of these agents, there is little information about the properties of these compounds. Like other NA, novichoks are organophosphorus compounds...
متن کاملPharmacology and Toxicology of Leflunomide
Leflunomide (LEF), used for rheumatoid arthritis, inhibits dihydro-orotate dehydrogenase (DHODH) and tyrosine kinase (TK) enzymes and has anti-inflammatory, lymphocyte proliferation regulatory, immunosuppression and chondroprotective effects. The most common adverse effects are gastrointestinal disorders, weight loss, hypertension, skin infection, and neurological and hematological toxicity. It...
متن کاملUranium on uranium collisions at relativistic energies
Deformation and orientation effects on compression, elliptic flow and particle production in uranium on uranium collisions (UU) at relativistic energies are studied within the transport model ART. The density compression in tip-tip UU collisions is found to be about 30% higher and lasts approximately 50% longer than in body-body or spherical UU reactions. The body-body UU collisions have the un...
متن کاملA Review on Toxicodynamics of Depleted Uranium
Depleted uranium (DU) is an important by product in uranium enrichment process. Due toits applications in civilian and also military activity, DU emerged as environmental pollutant.The exposure to DU can occur via external or internal pathways. In external exposure, mainlybeta radiation from the decay products contributes to DU toxicity. Internal exposure to DUis more im...
