The iron uptake in vitro of red cells from mice with hereditary microcytic anemia (gene symbol mk) was studied to examine the hypothesis of a generalized impairment of cellular iron uptake in this conidition. Reticulocyte-rich red cells from anemic (mk/mk) and acutely bled normal (+/+) mice were incubated in 59Fe-labeled mouse plasma and the radioiron uptake measured. The 59Fe uptake of the mk/...
In this work, Europium ion (Eu3+) substituted yttrium iron garnet particles EuxY3-xFe5O12 (x=0.0, 1.0, 2.0) were synthesized by the sol-gel method. X-ray diffraction (XRD) patterns confirmed the pure garnet structure for all samples. The garnet phase was studied by using Far-FTIR and Raman spectroscopy. The results of vibrating sample magnetometer (VSM) represents that saturation magnetization ...
Here we report a new, bench-top synthesis for iron/iron oxide core/shell nanoparticles via the thermal decomposition of Fe(η(5)-C(6)H(3)Me(4))(2). The iron/iron oxide core/shell nanoparticles are superparamagnetic at room temperature and show improved negative contrast in T(2)-weighted MR imaging compared to pure iron oxides nanoparticles, and have a transverse relaxivity (r(2)) of 332 mM(-1) s...
tepe sagzabad, a site situated on the qazvin plain of north-central iran, was excavated from 1970 to 1998 by the institute ofarchaeology of tehran university. recent excavations by h. tala’i (1997-1999) yielded some metal artifacts dating to theearly iron age. ten of these copper-based samples were investigated using inductively coupled plasma optical emissionspectroscopy (icp-oes), scanning el...

Iron oxide nanoparticles were synthesized for the first time using electrical arc discharge between a pair of highly pure titanium electrode without using metallic iron electrodes in iron chloride salt solution. The produced nanoparticles were characterized using various analyses such as X-ray Diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS). XRD and XPS analyses showed formation of...
