ingestion and inhalation of phosphine are 2 forms of toxicity and their clinical manifestation is extremely wide. a 22-year-old girl was admitted with complaints of nausea, vomiting and epigastric pain after eating lunch. she had a history of celiac disease. on arrival, she was alert and hemodynamically stable. there was not any abdominal tenderness or guarding. food poisoning treatment initiat...

Polymeric phosphate aluminum-ferric chloride (PPAFC) in this study was prepared. In order to obtain the optimum conditions for preparation of PPAFC, resulting in a better turbidity removal efficiency, parameters such as the molar ratio of Al/Fe, P/(Al+Fe), OH/(Al+Fe) as well as the reaction temperature were examined. Results showed that the optimal synthetic conditions were Al/Fe of 6:4, P/(Al+...

While iron release from enterobactin-mediated iron transport occurs primarily via an esterase that destroys the siderophore, other catechol siderophores that are not susceptible to hydrolysis act as bacterial growth factors. Elucidating the structures of protonated ferric enterobactin may reveal the pathway by which synthetic analogues fulfill bacterial iron requirements. In order to more compl...

The influence of framework substituents (Al3+, Ga3+, Fe3+ and B3+) and morphology (bulk vs. nanometer-sized sheets) of MFI zeolites on the acidity and catalytic performance in the methanol-to-hydrocarbons (MTH) reaction was investigated. The Brønsted acid density and strength decreased in the order Al(OH)Si>Ga(OH)Si>Fe(OH)Si≫B(OH)Si. Pyridine 15N NMR spectra confirmed the differences in the Brø...

in this work, ferric coagulation and acid cracking as olive mill wastewater (omw) pretreatments during photocatalysis process were compared in batch recirculation reactor. as ferric ions influence, ferric coagulation has preference over acid cracking. ferric ions influence on intensification of penolic components absorption on tio2 surfacein initial and oxidize organic pollutant during photocat...

Introduction: Controlling parenchymal hemorrhage, especially in liver, is still one of the challenges surgeons face with when they try to save the patients’ lives despite improvements in surgical procedures. There is a research contest between the researchers in this field to introduce more effective methods. This study aimed to compare the hemostatic effect of ferric sulfate and ferric chlo...

The effect of Kevlar fibre surface modification and hybridization on metal laminates (FMLs) was investigated in this paper. Fibre are interlaced layers thin metals fibre-reinforced plastics that constitute a hybrid composite material. flexural strength composites from the three-point bending test at various ratios sequence FML composites. Glass fibre, aluminum were taken for laminating reinforc...

For decades, a link between increased levels of iron and areas of Alzheimer's disease (AD) pathology has been recognized, including AD lesions comprised of the peptide β-amyloid (Aβ). Despite many observations of this association, the relationship between Aβ and iron is poorly understood. Using X-ray microspectroscopy, X-ray absorption spectroscopy, electron microscopy and spectrophotometric ir...

The complexation reaction between metal cations o f different valence states (Al, Bi(III), Cr(III), Fe(III); Ca, Co(II), Cu(II), Mn(II), Ni(II), Pb(II), Zn; Na) and fulvic acids is investi­ gated by the streaming current detection technique. It can be shown that the metal complexa­ tion capacity does not only depend on the nature o f the cation but also on the origin o f fulvic acids, which wer...
