Basic Method of Protection * Time * The amount of exposure is directly proportional to the duration of exposure. * As the length of exposure time increases‚ the radiation dose received increases in direct proportion. * During fluoroscopy‚ reduced exposure time will decrease both the patient and personnel exposure. * Fluoroscopic x-ray units are equipped with 5

2010-2011. To find out LD50 dose for the seed and further investigate the influence on germination and seedling parameters. The experimental results revealed that the percentage of germination had decreased after irradiation and the effect become stronger with increase of gamma dose. Parameters such as germination percentage‚ speed of germination‚ mean daily germination‚ peak value and germination value had significantly decreased with increased irradiation doses. Similarly seedling parameters

GENERAL APPROACHES FOR DOSE ADJUSTMENT IN RENAL DISEASE Renal insufficiency can markedly alter one or more of the pharmacokinetic parameters of a drug including oral bioavailability‚ volume of distribution‚ drug binding to plasma proteins‚ and most importantly the rates of metabolism and excretion‚ i.e.‚ drug clearance.. To minimize drug toxicity and maximize therapeutic benefits‚ it is often necessary to adjust drug dosage in proportion to the degree of renal insufficiency. A drug will most

An enabling aspect of our Phase 2 effort will be use of two improved models‚ including our novel 2-dose CP model in mice developed in Phase 1 that for the 1st time‚ reproduces the AKI and CKD pattern in humans treated with CP. Given the potential advantages a peptide agonist vs. RNLS protein‚ including reduced potential for cardiovascular side effects and immunogenicity; ease of manufacturing and stronger intellectual property‚ we will confirm and extend that a peptide agonist is equal or better
