Ferritin is a major iron storage protein. In case of iron deficiency, serum ferritin levels play a critical role in diagnosis and treatment.[1] Serum ferritin is an acute phase protein. Serum ferritin level is an indicator of body iron stores and may be normal or elevated in infective, inflammatory, or malignant disease.[2] Iron ions will be precipitated on the enamel surface as thin acid-resis...

Analysis of soil samples collected from sewage and tube well irrigated soils of Ludhiana, Amritsar Jalandhar and Mandi Gobindgarh, revealed that Diethylene triamine pentaacetic acid extractable nickel ( DTPA-Ni) was found to be higher in sewage fed soils. Sewage irrigation increased soil DTPA-Ni content by 3.04 times over the tube well irrigated soils. The content of DTPA-Ni showed decreasing t...

UNLABELLED The transformation of ferrihydrite to stable iron oxides over time has important consequences for biogeochemical cycling of many metals and nutrients. The response of methanogenic activity to the presence of iron oxides depends on the type of iron mineral, but the effects of changes in iron mineralogy on methanogenesis have not been characterized. To address these issues, we construc...

This study mainly concentrates on metallurgical structure of the ferrous ancient crafts, specially the discovered ferrous man-made pieces in Ilam which are aged more than 3000 years. The pieces were discovered in Ize a town located in the south east of Ahvaz , in the southern of Iran. The crafts include an ferrous bar, a 3-side and a 4 side bayonets which were microscopically studied by Electro...

The bioavailability and transport of particle-reactive pollutants are influenced by their partitioning between dissolved and particulate phases. We explored the importance of particle complexation to the arsenic cycle in an urban lake (Upper Mystic Lake, eastern MA, USA) that experiences arsenic remobilization from contaminated sediments during seasonal hypolimnetic anoxia. Particle size distri...

A laboratory investigation was conducted to evaluate the efficiency of four phosphate fertilizers, including diammonium phosphate (DAP), potassium phosphate monobasic (MPP), calcium superphosphateon (SSP), and calcium phosphate tribasic (TCP), in terms of the toxicity and bioavailability of Cd in contaminated soils. The efficiency of immobilization was evaluated on the basis of two criteria: (a...

Natural occurring iron oxides, such as Fe2O3, Fe3O4, and FeO, are abundant on Earth's surface feature many implications in our daily life since the Iron Age, final epoch of prehistory humanity. The physics oxides is at frontier physical research due to their complicated magnetic electronic properties. What makes it even more intriguing introduction pressure, which not only regulates crystal str...

The rate constants for in situ arsenic redox transformations in the surface waters of a eutrophic lake were estimated from observed horizontal heterogeneity in the arsenic species concentrations in the epilimnion of the Upper Mystic Lake. The smallest rate constants necessary to explain the observed horizontal heterogeneities were 10 times higher than rate constants estimated from monthly profi...

Chickpea-chelating peptides were purified and analysed for their iron-chelating activity. These peptides were purified after affinity and gel filtration chromatography from a chickpea protein hydrolysate produced with pepsin and pancreatin. Iron-chelating activity was higher in purified peptide fractions than in the original hydrolysate. Histidine contents were positively correlated with the ir...
