Motion and twisting of magnetic particles ingested by alveolar macrophages in the human lung: effect of smoking and disease
BioMagnetic Research and Technology - Tập 4 - Trang 1-14 - 2006
Winfried Möller, Winfried Barth, Martin Kohlhäufl, Karl Häussinger, Wolfgang G Kreyling
Magnetic microparticles being ingested by alveolar macrophages can be used as a monitor for intracellular phagosome motions and cytoskeletal mechanical properties. These studies can be performed in the human lung after voluntary inhalation. The influence of cigarette smoking and lung diseases on cytoskeleton dependent functions was studied. Spherical 1.3 μm diameter ferrimagnetic iron oxide partic... hiện toàn bộ
Analytical and preparative applications of magnetic split-flow thin fractionation on several ion-labeled red blood cells
BioMagnetic Research and Technology - - 2006
Horng-Jyh Tsai, Fang Ying, C. Bor Fuh
Abstract Background Magnetic Split-flow thin (SPLITT) fractionation is a newly developed technique for separating magnetically susceptible particles. Particles with different field-induced velocities can be separated into two fractions by adjusting applied magnetic forces and flow-rates at inlets and outlets. Methods Magnetic particles, Dynabeads, were used to test this new approach of field-induc... hiện toàn bộ
Simultaneous suppression of disturbing fields and localization of magnetic markers by means of multipole expansion
BioMagnetic Research and Technology - Tập 2 - Trang 1-8 - 2004
Bernd Hilgenfeld, Jens Haueisen
Magnetically marked capsules serve for the analysis of peristalsis and throughput times within the intestinal tract. Moreover, they can be used for the targeted disposal of drugs. The capsules get localized in time by field measurements with a superconducting quantum interference device (SQUID) magnetometer array. Here it is important to ensure an online localization with high speed and high suppr... hiện toàn bộ
Action of combined magnetic fields on aqueous solution of glutamic acid: the further development of investigations
BioMagnetic Research and Technology - Tập 6 - Trang 1-7 - 2008
Livio Giuliani, Settimio Grimaldi, Antonella Lisi, Enrico D'Emilia, Natalia Bobkova, Mikhail Zhadin
In the present work the results of the known investigation of the influence of combined static (40 μT) and alternating (amplitude of 40 nT) parallel magnetic fields on the current through the aqueous solution of glutamic acid, were successfully replicated. Fourteen experiments were carried out by the application of the combined magnetic fields to the solution placed into a Plexiglas reaction vesse... hiện toàn bộ
Effects of electromagnetic fields of low frequency and low intensity on rat metabolism
BioMagnetic Research and Technology - Tập 6 Số 1 - 2008
Gabriele Gerardi, A. De Ninno, Marco Prosdocimi, V. Ferrari, Filippo Barbaro, Sandro Mazzariol, Daniele Bernardini, G. Talpo
Abstract A series of experiments on rats have been performed, to study the effects of long time (50 days) exposure to electromagnetic fields of extremely low frequency (ELF, i.e. less than 100 Hz) and amplitude (non thermal), testing whether the metabolic processes would be affected. The background lies on recent observations on the behaviour of isolated enzymes in vitro exposed to EFL fields. In ... hiện toàn bộ
Correlations from gadopentetate dimeglumine-enhanced magnetic resonance imaging after methotrexate chemotherapy for hemorrhagic placenta increta
BioMagnetic Research and Technology - - 2003
Salim A Wehbe, Labib M Ghulmiyyah, Kenneth T Carroll, Mark Perloe, Daniel G Schwartzberg, E Scott Sills
To describe pre- and post-methotrexate (MTX) therapy images from pelvic magnetic resonance imaging (MRI) with gadopentetate dimeglumine contrast following chemotherapy for post-partum hemorrhage secondary to placenta increta. A 28-year-old Caucasian female presented 4 weeks post-partum complaining of intermittent vaginal bleeding. She underwent dilatation and curettage immediately after vaginal de... hiện toàn bộ

Size dependent heat generation of magnetite nanoparticles under AC magnetic field for cancer therapy
BioMagnetic Research and Technology - Tập 6 - Trang 1-9 - 2008
Jun Motoyama, Toshiyuki Hakata, Ryuji Kato, Noriyuki Yamashita, Tomio Morino, Takeshi Kobayashi, Hiroyuki Honda
We have developed magnetic cationic liposomes (MCLs) that contained magnetic nanoparticles as heating mediator for applying them to local hyperthermia. The heating performance of the MCLs is significantly affected by the property of the incorporated magnetite nanoparticles. We estimated heating capacity of magnetite nanoparticles by measuring its specific absorption rate (SAR) against irradiation ... hiện toàn bộ
Magnetic techniques for the isolation and purification of proteins and peptides
BioMagnetic Research and Technology - Tập 2 - Trang 1-17 - 2004
Ivo Safarik, Mirka Safarikova
Isolation and separation of specific molecules is used in almost all areas of biosciences and biotechnology. Diverse procedures can be used to achieve this goal. Recently, increased attention has been paid to the development and application of magnetic separation techniques, which employ small magnetic particles. The purpose of this review paper is to summarize various methodologies, strategies an... hiện toàn bộ
