Chelated Iron

Abstract Iron raises to toxic levels in mitochondria of excitable cells in some forms of neuro-degeneration with brain accumulation (NBIA), in sideroblastic anemia and in Friedreich’s ataxia (FA), often leaving the cytosol iron-depleted. In anemia of chronic disease (ACD) iron is withheld by macrophages, while iron levels in extracellular fluids (e.g. plasma) are drastically reduced. Although excessive iron deposition occurring in organs of iron overloaded (IO) patients can be reduced with iron chelators, it is uncertain whether this is applicable to conditions where iron accumulates within selected tissues/cells in the absence of systemic IO. Objective. We assessed whether deferiprone (DFP), a membrane-permeant bidentate chelator in clinical use for treating systemic IO, might serve as an iron relocating agent in settings of regional iron accumulation by a. capturing labile iron accumulated in cell compartments and b. conveying the chelated iron either to other cell locations for metabolic integration or to transferrin for systemic reutilization. Methods. DFP capacity to shuttle iron intracellularly and transcellularly was assessed in macrophages (J774) and heart (H9c2) cell models using organelle-targeted fluorescent iron-sensors in conjunction with fluorescence microscopy imaging. We employed pairs of sensors targeted to different cell compartments and iron-evoked quenching and chelator-evoked dequenching as means to trace DFP mediated iron transfer. Mitochondrial iron accumulation was generated with succinylacetone or by silencing genes affecting mitochondrial iron metabolism. Results. DFP facilitated iron transfer: a. from iron-laden cell organelles to other cell compartments or to medium (and vice versa) and b. from iron loaded macrophages to pre-erythroid MEL cells (for chemically induced hemoglobin synthesis) either directly or via transfer to extracellular transferrin. Discussion The results of this study indicate that relocation of cell accumulated iron can be used as a modality of chelation for treating conditions of regional iron accumulation by applying chelators able to permeate into cell compartments but also to transfer the chelated iron to cell acceptors or to the extracellular iron carrier transferrin.

The study was carried out to analyse plant nutrient elements present in soil samples from different part of Pokhara metropolitan city and to compare them with standard recommended values. The plant nutrient elements of soil samples nitrogen, phosphorus, potash, zinc, iron, copper, and boron were analyzed by using specific techniques. The PH was analysed by PH meter, organic matter by gravimetric method, nitrogen by Kjeldal method and phosphorus by Olsen’s method (1954) of analysis. Similarly, the amount of zinc, iron and copper were determined by chemical method, potassium by flame photometer method, and boron by using a spectrophotometer. The essential macronutrients nitrogen, phosphorus and potash remained within the permissible limit for most of the samples. The essential micronutrients zinc, copper and boron in four samples were within the acceptable range. The content of iron was higher than that required as an essential crop nutrient. The observed values of plant nutrient elements expressed that the sampling area could be used for agricultural cultivation and production.

Major Factors

Nutrient elements, one of the major factors shaping plant development, are the major components of plants, and, after being taken from the soil, they are present in different organs of plant at different concentrations. The speciation of nutrient elements within plant body is vital importance for determining the contribution to plant development, knowing the transfer between organs within the body of organs, clearly understanding the factors influencing plant development, and shaping the plant development. In the present study, the change of the concentrations of K and Mg (macronutrient elements) and Cu (micronutrient elements) by species and organ in woody species Prunus cerasifera, Platanus orientalis, Acer negundo, Fraxinus excelsior, Catalpa bignonioides, Aesculus hippocastanum, and Tilia platypyllos. As a result, it was found that the changes of elements by species were statistically significant in all the organs, and, in general, the highest concentrations were observed in leaves. The study results revealed that the concentrations of these elements might significantly vary between the organs in the same species, which varies significantly by the species.
