The involvement of magnetic fields in basic cellular processes has been studied for years. Most studies focus their results on a single frequency and intensity. Intensity long the central parameter hypotheses interaction between cells fields; however, always played secondary role. main objective this study was to obtain specific that allows reduction viability proliferation glioblastoma (CT2A) neuroblastoma (N2A) cell models. These were compared with an astrocyte model (C8D1A) (nontumor)...
The frequency of a magnetic field has led to the development physicochemical interaction models and consideration role as fundamental parameter in change cell behavior. main objective this article is find window decrease viability proliferation different tumor lines compare response each. For purpose, PC12 (rat), B16F10 (mouse), SKBR3 (human), MDA-MB-231 non-tumor line 3T3 (mouse) are exposed 100 µT for 24, 48, 72 hours windows contained range [20–100] Hz, their behavior evaluated. results...
In vitro studies requiring controlled exposure to low-frequency electromagnetic fields employ systems with different geometries and configurations, the Helmholtz configuration being one of most widely used. This has limitations in homogeneity spatial distribution magnetic field intensity values. We present design, manufacturing, characterisation a new coil system, called RILZ configuration, which improves values three dimensions space for heights comparison traditional circular coils...
The main objective of this article is to demonstrate through experimental means the capacity quartz crystal resonator (QCR) characterize biological samples aqueous dilutions hyaluronic acid according their viscosity and how may be useful in potential diagnosis arthritic diseases. synovial fluid viscous due presence acid, synthesized by lining cells (type B), secreted into thus making viscous. In consequence, used as emulate fluid. Due viscoelastic pseudo-plastic behavior it necessary use...
Viscosity variation in human fluids, such as Synovial Fluid (SF) or Cerebrospinal (CSF), can be used a diagnostic factor; however, the sample volume obtained for analysis is usually small, making it difficult to measure its viscosity. On other hand, Quartz Crystal Resonators (QCR) have been widely sensing applications due their accuracy, cost, and size. This work provides design validation of new viscosity measurement system based on quartz crystal resonators low leading development sensor...
A novel compact device with spectrum analyzer characteristics has been designed, which allows the measuring of maximum power received in multiple narrow frequency bands 300 kHz, recording entire from 78 MHz to 6 GHz; is capable communications and detecting sources electromagnetic fields using same band. The proposed permits evaluation cross-talk effect that, conventional exposimeters, generates a mistake estimation fields. was calibrated an anechoic chamber for far-fields validated against...
