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
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

The effects of weak magnetic and electromagnetic fields in biology have been
intensively studied on animals, microorganisms and humans, but comparably less
on plants. Perception mechanisms were attributed originally to ferrimagnetism,
but later discoveries required additional explanations like the "radical pair
mechanism" and the "Ion cyclotron resonance" (ICR), primarily considered by
Liboff. The... hiện toàn bộ
Magnetic separation technology, using magnetic particles, is quick and easy
method for sensitive and reliable capture of specific proteins, genetic material
and other biomolecules. The technique offers an advantage in terms of subjecting
the analyte to very little mechanical stress compared to other methods.
Secondly, these methods are non-laborious, cheap and often highly scalable.
Moreover, tech... hiện toàn bộ

To quantitatively compare in-vitro and in vivo membrane transport studies of
targeted delivery, one needs characterization of the magnetically-induced
mobility of superparamagnetic iron oxide nanoparticles (SPION). Flux densities,
gradients, and nanoparticle properties were measured in order to quantify the
magnetic force on the SPION in both an artificial cochlear round window membrane
(RWM) mode... hiện toàn bộ
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
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
