Possible therapeutic applications of pulsed magnetic fields [Czech]
Abstract Magnetotherapy is a relatively new, nowadays however, relatively widespread method in several medical disciplines. The mechanism proper of the favourable action of the pulsed…
Melatonin and its relation to the immune system and inflammation
Abstract Melatonin (N-acetyl-5-methoxytryptamine) was initially thought to be produced exclusively in the pineal gland. Subsequently its synthesis was demonstrated in other organs, for example, the…
The effects of pulsing magnetic fields on pineal melatonin synthesis in a teleost fish (brook trout, Salvelinus fontinalis)
Abstract Based on findings in various mammalian species, where exposure to electromagnetic fields decreased the nocturnal synthesis of the pineal secretory product melatonin, we investigated…
Beneficial effects of electromagnetic fields
Abstract Selective control of cell function by applying specifically configured, weak, time-varying magnetic fields has added a new, exciting dimension to biology and medicine. Field…
Melatonin: reducing the toxicity and increasing the efficacy of drugs
Abstract Melatonin (N-acetyl-5-methoxytryptamine) is a molecule with a very wide phylogenetic distribution from plants to man. In vertebrates, melatonin was initially thought to be exclusively…
Potential biological consequences of excessive light exposure: melatonin suppression, DNA damage, cancer and neurodegenerative diseases
Abstract This brief review summarizes some of the biological effects of light exposure at an inappropriate time (during the normal dark period) and the potential…
Microcirculatory effects of pulsed electromagnetic fields
Abstract PURPOSE: Pulsed electromagnetic fields (PEMF) are used clinically to expedite healing of fracture non-unions, however, the mechanism of action by which PEMF stimulation is…
Enhancing analogic reasoning with rTMS over the left prefrontal cortex
Abstract The authors utilized repetitive transcranial magnetic stimulation (rTMS) in 16 normal volunteers to investigate the role of the left dorsolateral prefrontal cortex (PFC) in…
Improved executive functioning following repetitive transcranial magnetic stimulation
Abstract The cognitive effects of active and sham repetitive transcranial magnetic stimulation (rTMS) were examined in 19 middle-aged and elderly patients with refractory depression. Patients…
Effect of pulsed magnetic fields on triglyceride and cholesterol levels in plasma of rats
Abstract Sexual dysfunction is common in patients with Parkinson’s disease (PD) since brain dopaminergic mechanisms are involved in the regulation of sexual behavior. Activation of…
