Introduction Endothelial progenitor cells (EPC) are promising candidates for novel stem cell transplantation strategies to treat cardiovascular diseases. Within this study formations of vascular network structures with super paramagnetic iron oxide (SPIO) loaded EPCs were induced, which is an in vitro correlate of the vasculogenesis process [1]. The resulting endothelial network showed to be an...

Introduction: Positive-contrast imaging of super paramagnetic iron oxide (SPIO)labeled cells avoids problems associated with negative contrast such as other signal voids and partial volume effects [1-7]. Many techniques offer 2D imaging with thick slices and long scan times. A fast 3D alternating repetition time (ATR) SSFP [8] method with reliable on-resonant suppression has recently been intro...

in this study we report the rock magnetic properties of surface soil samples and their spatialvariability from the northernmost district of kerala to understand pedogenic processes and soil erosion. themagnetic signal is mainly from fine grained pedogenic magnetite as other sources like anthropogenic andlithogenic magnetite, bacterial magnetite and greigite are absent. the surface soil samples ...

INTRODUCTION Super-paramagnetic iron oxide (SPIO) particles can label macrophages and monocytes in circulation; the effects of these labeled cells can then be detected by T2*-weighted MRI [1]. This has enormous potential for imaging inflammatory responses in the heart, but it has been difficult to do in vivo using conventional methods for free-breathing, ungated imaging. Subspace imaging with t...

In this work, preparation and crystallization of yttrium iron garnet Y3Fe5O12 super-paramagnetic nanoparticle by aqueous sol–gel processes and its application as an effective nano catalyst for esterification and etherification reactions in short reaction time and in high isolated yields. Then this catalist was used for the synthesis of Dihydropyrimidin derivatives is described. The catalyst was...
