The title salt, [Fe(II)(C4H3ClN2)2(H2O)4](C7H7O3S)2, contains a complex cation with point group symmetry 2/m. The high-spin Fe(II) cation is hexa-coordinated by four symmetry-related water and two N-bound 2-chloro-pyrazine mol-ecules in a trans arrangement, forming a distorted FeN2O4 octa-hedron. The three-dimensional supra-molecular structure is supported by inter-molecular O-H⋯O hydrogen bond...
The electronic properties of an unusually redox-rich iron system, [PhBP3]FeONx (where [PhBP3] is [PhB(CH2PR2)3] ), are explored by Mössbauer, EPR, magnetization, and density-functional methods to gain a detailed picture regarding their oxidation states and electronic structures. The complexes of primary interest in this article are the two terminal iron(IV) nitride species, [PhBP3]Fe'N (3a) and...
BACKGROUND Primary iron overload in African Americans has been reported predominantly from autopsy studies. METHODS We characterized hepatic iron phenotypes in 83 African Americans who underwent liver biopsy during the interval 1990 to 1995. We tabulated pathology report form data, iron grades in hepatocytes (0-4) and Kupffer cells (0-3) and abnormal liver histology. Increased iron was define...
background: today the use of natural substances plays a major role in improving the growth and immunity of aquatic organisms. objectives: the purpose of the present study was to evaluate the effects of iron nanoparticles with lactobacillus casei as a probiotic on growth parameters and probiotic counts in rainbow trout intestine. methods: seven hundred and twenty fish with 12±0.49 g initial weig...
background: no study has been conducted on iron requirements of broiler breeder hens until now. objectives: the purpose of the present study was to determine the iron requirement of broiler breeder hens using nonlinear models. methods: forty eight (cobb 500) broiler breeder hens were individually placed in galvanized wire cages. in order to depletion of hens iron reserved, hens were offered a s...
How often elevated serum ferritin in primary-care patients reflects increased iron stores (normally 0.8 g in men, 0.4 g in women) is not known. The Hereditary Hemochromatosis and Iron Overload Screening (HEIRS) study screened 101,168 primary-care participants (44% Caucasians, 27% African-Americans, 14% Asians/Pacific Islanders, 13% Hispanics, 2% others). Follow-up clinical evaluation was perfor...
Polyethersulfone (PES) based nanocomposite nanofiltration membrane was prepared by immersion precipitation method and casting solution technique using poly (acrylic acid) grafted-iron oxide nanoparticles (Fe3O4) as hydrophilic filler additives. For this purpose, iron oxide nanoparticles were modified by in situ polymerization of acrylic acid in aqueous solution by potassium persulfate as initi...
Transferrin receptor-2 (TFR2) regulates hepatic hepcidin secretion and when mutated causes type-3 hemochromatosis. No functional study is available in humans. We studied a 47 year-old woman with hemochromatosis. TFR2 DNA and its hepatic transcript were directly sequenced. Hepatic expression of hepcidin and other iron-related genes were measured by qRT-PCR. Urinary hepcidin was measured at basel...
this dissertation has six chapter and tree appendices. chapter 1 introduces the thesis proposal including description of problem, key questions, hypothesis, backgrounds and review of literature, research objectives, methodology and theoretical concepts (key terms) taken the literature and facilitate an understanding of national security, national interest and turkish- israeli relations concepts...
