Adsorption of dissolved phosphate onto iron-hydroxides has been shown to be one of the primary regulators of phosphorus cycling in sediments. Bioturbation and bioirrigation by benthic infauna modify this cycling by accelerating the transport of dissolved and particulate phosphorus and by changing rates of reactions that occur in the sediment, such as the adsorption of phosphate by amorphous iro...

Residual sludge is a significant waste resource, and the preparation of biochar achieves disposal. Biochar has high uptake capacity for phosphate. To prepare adsorbent phosphate, was chemically anaerobically treated in presence iron salts pyrolyzed. We investigated effects pyrolysis temperature salt on phosphate capacity, finding that pretreatment with removed intrinsic thus improving ability. ...

The expression of virulence determinants in Pseudomonas aeruginosa is coordinately regulated in response to both the social environment--commonly referred to as quorum sensing--and to environmental cues. In this study we have dissected the various independent regulation levels for pyocyanin production, which is influenced by the homoserine lactone- and Pseudomonas quinolone signal (PQS)-mediate...

Glutathione-bound gold nanoclusters (AuNCs@GSH) can emit reddish photoluminescence under illumination of ultraviolet light. The luminescence of the AuNCs@GSH is quenched when chelating with iron ions (AuNCs@GSH-Fe(3+)), presumably resulting from the effective electron transfer between the nanoclusters and iron ions. Nevertheless, we found that the luminescence of the gold nanoclusters can be re...

We examined the bioavailability of iron-storage proteins—including representatives of maxiand miniferritins—to various species of marine phytoplankton. Both eukaryotic and prokaryotic species were able to grow rapidly with horse spleen ferritin (HoSF) or deoxyribonucleic acid (DNA)-binding proteins from starved cells (Dps) from Trichodesmium erythraeum as the sole Fe source in the medium. In th...

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...

Background: The role of phosphate hemostasis in development of thalassemia bone disease has not been extensively studied yet. Due to the lack of sufficient human studies about the changes of serum Fibroblast growth factor-23(FGF23) in patients with beta-thalassemia major as the first step of investigating the role of FGF23 in thalassemia bone disease, the present study aimed to investigate the ...
