WebRadiosensitivity differs in humans and likely among primates. The reasons are not well known. We examined pre-exposure gene expression in baboons (n = 17) who developed haematologic acute radiation syndrome (HARS) without pancytopenia or a more aggravated HARS with pancytopenia after irradiation. We evaluated gene expression in a two stage … This method starts with a solution of hydrogen peroxide and sulfuric acid. To this a solution containing potassium iodide, sodium thiosulfate, and starch is added. There are two reactions occurring simultaneously in the solution. In the first, slow reaction, iodine is produced: H2O2 + 2 I + 2 H → I2 + 2 H2O WebIf the concentration of iodine (I2) is allowed to build up as the reaction proceeds then the rate of the reverse reaction will increase and an equilibrium mixture will result. Any rate measured for the reaction under such conditions will not represent the rate of the forward reaction but the net difference between the forward and reverse rates. imersion training speargun
