A case-control study was performed to investigate the autonomic nervous function in vibration syndrome. The subjects were 20 patients with a history of Raynaud's phenomenon (vibration white finger (VWF) (+) group), 20 patients without such a history (VWF(-) group), and 20 healthy workers (control group). Their ages and years under medical treatment for vibration syndrome were matched individual...

The concentrations of norepinephrine in hypothalamus and norepinephrine and epinephrine in head kidney were significantly decreased in treated tilapia (Oreochromis aureus) during the time course of cold exposure (12 degrees) as compared to the control (25 degrees). The elevation of norepinephrine and epinephrine in plasma was detected earlier than that of cortisol in cold-treated tilapia. Phago...

Most theoretical wave models require the power in the wave magnetic field in order to determine the effect of chorus waves on radiation belt electrons. However, researchers typically use the cold plasma dispersion relation to approximate the magnetic wave power when only electric field data are available. In this study, the validity of using the cold plasma dispersion relation in this context i...

A compact and portable 300 GHz collective scattering diagnostic employing a homodyne detection scheme has been constructed and installed on the hot helicon experiment (HELIX). Verification of the homodyne detection scheme was accomplished with a rotating grooved aluminum wheel to Doppler shift the interaction beam. The HELIX chamber geometry and collection optics allow measurement of scattering...

We investigate cylindrical and spherical solitons in electron-ion (EI) plasma that contains hot (cold) electrons with stationary ions. The magneto-hydrodynamic equations are solved the aid of reductive perturbation (RP) technique, leading to modified Korteweg–De Vries (mKdV) equation for non-linear behaviour solitary waves EI plasma. By employing reduced differential transform method (RDTM), an...

We find a sharp condition on the density-dependent coefficient of damping one-dimensional repulsive Euler-Poisson system, which makes it possible to suppress formation singularities in solution Cauchy problem with arbitrary smooth data. In context plasma physics, this means possibility suppressing breakdown oscillations cold plasma.

Cold electric discharge plasma can be in direct contact with the water solution being treated. Active species are generated directly and penetrate into through gas-liquid interface. Hot of pulsed remotely affect an object without causing any thermal damage to it, e.g., by means irradiating it. The effect light penetrating is fundamentally different from cold which solution: already contains all...

INTRODUCTION Guided treatments with nanoparticles and cold atmospheric plasma are a new approach in cancer therapy. Plasma is an ionized gas that has reactive and energetic particles and can be produced in the laboratory by different methods. MATERIAL AND METHODS Plasma jet therapy was employed to irradiate HCT-116 cells (human colorectal cancer cells) which were cultured in the presence of g...

The need for effective and safe therapies cancer is growing as aging modifying its epidemiology. Cold atmospheric plasma (CAP) has gained attention a potential anti-tumor therapy. CAP gas with enough energy to ionize significant fraction of constituent particles, forming equal numbers positive ions electrons. Timely-resolved output voltage measurement, emission spectroscopy, quantification reac...
