A new method of cancer treatment is proposed, based on the unique magnetic properties of ferritin iron core which, in alternating magnetic field of frequency approximately 100 kHz, is easily heated to temperatures sufficiently high to destroy neoplastic cells containing an excess of this protein, without damaging the normal cells.
Antioxidative capabilities of carboxymethylated (1 --> 3)-beta-D-glucan from Saccharomyces cerevisiae cell wall, alpha-tocopherol, and mannitol against lipid peroxidation in phosphatidylcholine liposomes induced by OH. radicals produced with Fenton's reagent (H(2)O(2)/Fe(2+)) were studied using absorption ultraviolet-visible spectrophotometry. It was found… (More)
On the basis of the physical properties of magnetic fluids a new technique of whole-body hyperthermia is proposed. Subdomain dextran stabilized magnetite particles injected into the blood-stream can be efficiently heated using an external high-frequency magnetic field, which allows rapid and controllable delivery of heat to the patient's blood, which may be… (More)
Measuring absorption spectra of conjugated dienes it has been shown that microwave radiation with a frequency of 2.54 GHz induces lipid peroxidation of phosphatidylcholine liposomes. The relationship with the previously observed microwave-enhanced liposome permeability is discussed.
One of the perspective methods of cancer chemotherapy is magnetic targeting of drugs to tumors. This task is usually accomplished using small permanent magnets attached near the desired sites. In this study a new much more effective approach is proposed which is based on a strong magnetic gradient using a ferromagnetic wire placed in a strong magnetic… (More)
Human serum albumin labeled with technetium-99m was encapsulated together with magnetite particles into phosphatidylcholine/cholesterol liposomes. In order to investigate the stability of this complex and its ability to be used for magnetic drug targeting, the in-vivo distribution after intravenous administration in rats was estimated. For in-vivo targeting… (More)
BACKGROUND Nanomaterials are at the leading edge of the rapidly developing field of nanotechnology. Magnetic nanoparticles for cancer therapy and diagnosis have been developed on the basis of their unique physico-chemical properties not present in other materials. Their versatility is widely exploited in such diverse techniques as cell and macromolecule… (More)
Large unilamellar magnetoliposomes (MLs) with encapsulated doxorubicin (DOX) (anticancer drug) were prepared by reverse-phase evaporation. They were exposed to an alternating magnetic field with a frequency of 3.5 MHz and an induction of 1.5 mT produced in three-turn pancake coil. The results showed that magnetoliposomes could be specifically heated to 42… (More)
Magnetic nanoparticles for therapy and diagnosis are at the leading edge of the rapidly developing field of bionanotechnology. In this study, we have theoretically studied motion of magnetic nano- as well as micro-particles in the field of cylindrical Halbach array of permanent magnets. Magnetic flux density was modeled as magnetostatic problem by finite… (More)
Polysaccharides represent the major part of the yeast cell wall dry weight and build the skeletal carcass defining cell wall stability and cell morphology (beta-D-glucans) or constitute amorphous matrix and cell surface fibrous material (mannans and mannoproteins). It is known that yeast cell wall beta-D-glucans reveal immunomodulating properties, which… (More)
