Plant accumulation of Fe and other metals can be enhanced under Fe deficiency. We investigated the influence of Fe status on heavy-metal and divalent-cation uptake in roots of pea (Pisum sativum L. cv Sparkle) seedlings using Cd2+ uptake as a model system. Radiotracer techniques were used to quantify unidirectional 109Cd influx into roots of Fe-deficient and Fe-sufficient pea seedlings. The con...

To determine the relationship between cellular uptake of cadmium and content of metallothionein, we measured uptake of 109Cd in cells that differed in content of metallothionein (MT). MT cells were derived from NIH/3T3 cells by transfection with a plasmid containing the genome of bovine papilloma virus and the mouse metallothionein-I gene, driven by the promotor for the glucose-regulated protei...

Nephrotoxic effects of cadmium exposure are well established in humans and experimental animals. An early manifestation of such toxicity is calciuria a few hours after injection of CdMT in rats. Protection against calciuria and other adverse effects such as proteinuria (occurring later) is offered by pretreatment with Cd, which effectively induces metallothionein synthesis. In the present exper...

Biliary excretion of cadmium was studied in two groups of five rats which were given repeated injections of 109Cd. The first group was given a total amount of 6 mg Cd/kg which was 6 times as much as the second group. The elimination of cadmium in bile, urine, and feces was measured 4 to 5 weeks after the last injection. The relative biliary excretion of cadmium was the same in both groupetion, ...

Background: Solid targets that consist of powder and electrodeposited targets are used commonly to produce radionuclides by accelerators. Since silver is easily electrodeposited in cyanide baths and has a very excellent thermal conductivity, the electrodeposited target is preferable to produce 109Cd. To avoid cracking or peeling of the target during bombardment, it should have a level surface a...

This research intends to unveil the presence of radioisotopes in soil some mining sites Nasarawa state using thermos-scientific interceptor (IdentiFINDER). The work aimed at detecting presence, types and trust level radioisotopes. result showed that, 103Pd 125I were found 57% total points percentage abundance detector reached 50-65% indicating those are likely area, 109Cd was 15% areas. for sho...
