In plasma medicine, ionized gases with temperatures close to that of vertebrate systems are applied to cells and tissues. Cold plasmas generate reactive species known to redox regulate biological processes in health and disease. Pre-clinical and clinical evidence points to beneficial effects of plasma treatment in the healing of chronic ulcer of the skin. Other emerging topics, such as plasma c...

Argon plasma treatment was used to modify the surface of atelocollagen films using a plasmochemical reactor. To evaluate the effects of the treatment, the untreated and treated samples were characterized by Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), Scanning Electron Microscopy (SEM) imaging, and X-ray Photoelectron Spectroscopy (XPS) techniques. Cell growt...

Abstract The article discusses the results of processing some catalysts used in chemical industry using plasma technologies. already production were treated vacuum with a beam argon ions addition oxygen. experiments carried out different values ion current and energy its ions. As result experiments, it turned that characteristics plasma-treated to be close those fresh catalysts.

We report experimental measurements of the axial plasma flow and the parallel ion temperature in a magnetized linear plasma device. We used laser induced fluorescence to measure Doppler resolved ion velocity distribution functions in argon plasma to obtain spatially resolved axial velocities and parallel ion temperatures. We also show changes in the parallel velocity profiles during the transit...

Effects of temperature stimuli on plasma glucagon levels were studied in fasted (18 hr) and shorn rats. Plasma glucagon levels rose significantly on exposures to both cold (-5 degrees C, 60 min) (p less than 0.001) and heat (36 degrees C, 60 min) (p less than 0.001) from that in control rats at 25 degrees C. Cold stimulus increased blood FFA level (p less than 0.001) and both cold and heat stim...

Silk fibroin (SF) is a natural, degradable, fibrous protein that is biocompatible, is easily processed, and possesses unique mechanical properties. Another natural material, wool keratose (WK), is a soluble derivative of wool keratin, containing amino acid sequences that induce cell adhesion. Here, we blended SF and WK to improve the poor electrospinability of WK and increase the adhesiveness o...

Abstract In this work, the surface of carbon cloth is treated by plasma jet to improve its hydrophilicity. The symmetrical cloth-based supercapacitor assembled with as active electrodes and sodium chloride solution electrolyte. With discharge time (1 min, 2 3 min) working gas types (argon, air, helium) variables, effects different on hydrophilicity are observed, changes electrochemical properti...

Context:  The major motivation for the preparation of the plasma derived biological medicine was the treatment of casualties from the Second World War.  Due to the high expenses for preparation of plasma derived products, achievement of self-sufficiency in human plasma biotechnological industry is an important goal for developing countries.Evidence Acquisition:  The complexity of the bloo...
