to establish biomagnetic research and technology as a new scientific
discipline.
Applied enzymology and biochemical
analysis
·
Several types of insoluble chromolytic substrates with black
chromogene for the determination of proteinase
(black gelatine), amylase
(black starch), cellulase
(black CM-cellulose) and dextranase
(black dextran) activities were developed. Black gelatin was used for the
determination of
effective
proteolytic activity in biodetergents.
·
Simple
procedures for rapid detection of proteinases (using either gelatine
or fibrin
as substrates), amylases,
dextranases,
proteinase
inhibitors and amylase
inhibitors in liquid samples (e.g., fractions after liquid chromatography)
were developed.
·
Acetylcholinesterases
of various origin were studied (screening
of microbial producers, isolation
from bovine erythrocytes)
·
A
simple procedure for direct
determination of total soil carbohydrate content was also developed.

BioMagnetic
Research and Technology: a new online journal

Magnetism represents an
interesting phenomenon that has attracted human attention for many years.
Nowadays, magnetism is the basic principle of many devices, procedures and
technologies. However, only relatively recently this phenomenon has also found
really important applications in various areas of biosciences and
biotechnologies.
There are not so many
examples of real magnetic structures connected with living beings.
Nanoparticles composed of magnetic iron oxides have been found in magnetotactic
bacteria, some animals and plants. However, majority of structures found in
living organisms are diamagnetic. Magnetic techniques used in biosciences and
biotechnology are thus predominantly based on magnetic labelling of otherwise
diamagnetic molecules, cell organelles or cells. Magnetic field itself, as well
as magnetic nano- and microstructures can influence specific physiological
functions of living beings under certain conditions.
Biomagnetic techniques have
already been used in different areas of natural sciences such as molecular and
cell biology, medicine, biochemistry, analytical and bioanalytical chemistry,
clinical diagnostics, virology, microbiology, parasitology, immunology,
biotechnology, environmental technology and some others. Nowadays, there is no
publication forum available to cover the entire area of biomagnetic research
and technology. Papers in this area can be found in hundreds of journals,
starting (in alphabetical order) with Abdominal Imaging and ending with Zhurnal
Mikrobiologii, Epidemiologii i Immunobiologii.
In this context, we are
proud to introduce BioMagnetic Research
and Technology http://www.biomagres.com/start.asp,
a new on-line forum for cutting-edge findings in this multidisciplinary area of
research.
As already written on the
WWW pages of BioMagnetic Research and
Technology, this journal is intended as a forum for the disclosure and
discussion of the entire spectrum of biomagnetic research and technology. The
journal will encourage greater interaction between basic and applied research,
as well as cooperation between various scientific disciplines.
The journal will accept
papers on all aspects of biomagnetic research and technology. The following
areas, however, are of special interest:
• biological, medical,
environmental and related systems and processes involving magnetic nano- and
micro structures, and paramagnetic molecules
• the effects of magnetic
fields to biosystems
• construction of magnetic
biocompatible, biodegradable and biomimetic systems
• application of basic
biomagnetic research in biosciences, biotechnology, environmental technology
and related areas
Our new journal will bring
several benefits both to the readers and authors. The papers published in BioMagnetic Research and Technology will
be freely accessible to everybody on the journal WWW page http://www.biomagres.com/start.asp
free of charge. The journal is indexed in PubMed, a well-known on-line medical
database, and the papers will be permanently archived in PubMed Central http://www.pubmedcentral.nih.gov/,
the National Institute of Health's repository for biomedical research articles.
The manuscripts will be submitted and manipulated electronically, saving thus
manipulation delays. There is no limitation as to the article length, number of
colour figures etc., and supplementary or documentary data can be included in
the article. Due to the speed of publication, there will be no loss of priority
of the published results.
As mentioned above, BioMagnetic Research and Technology is
cost-free for the readers, but, unfortunately, it is not cost-free for the
authors. The publishers administration and maintaining the computational
facilities require substantial cost. Therefore there is a flat $500 charge for
each article accepted. However, BioMagnetic
Research and Technology has been granted a moratorium for the first six
months. In addition, Editors are allowed to grant a waiver for a limited number
of authors from disadvantaged countries. We would also like to inform the
future authors that it is possible for their Institutions to become partners of
BioMed Central under very reasonable conditions, leading to the possibility of
all the Institutes researchers to publish free of charge in all the journals
published by BioMed Central:
http://www.biomedcentral.com/info/about/instmembership.
Our aim is to increase the
scientific value of BioMagnetic Research
and Technology. In cooperation with BioMed Central we will look for the
possibility to index our journal also in other databases such as Web of
Science, Chemical Abstracts, Biological Abstracts etc. After an appropriate
period, Institute for Scientific Information will be asked to evaluate our
journal and, if possible, to add it to the list of scientific journals with
Impact Factor. These attempts will, of course, require the active participation
of the authors to submit their high quality papers to this journal, and to cite
the papers published in BioMagnetic
Research and Technology in manuscripts submitted to other journals.
As Editors-in-Chief, and on
behalf of the journal Editorial Board, we welcome all the future authors and
readers to participate in our activity. BioMagnetic
Research and Technology is now the fastest way how to publish results of
your high quality research in various areas of biomagnetic research and
technology, enabling almost unlimited access to your results by your colleagues
and partners.
