Radioprotective thermally generated free-radical dextrins

Fast onset medications through thermally generated aerosols.

Smoking involves heating a drug to form a mixture of drug vapor and gaseous degradation products. These gases subsequently cool and condense into aerosol particles that are inhaled. Here, we demonstrate rapid and reliable systemic delivery of pure pharmaceutical compounds without degradation products through a related process that also involves inhalation of thermally generated aerosol. Drug is...

Application of EPR Spectroscopy to Examination of Free Radical Formation in Thermally Sterilized Flumetasone

Thermal formation of free radicals in flumetasone sterilized according to the pharmaceutical norms at 160, 170 and 180 °C was examined by electron paramagnetic resonance (EPR) spectroscopy. The microbiological analysis was done. Similar free radical concentrations were measured for flumetasone sterilized at 160 and 170 °C. The concentration was considerably higher than that for flumetasone ster...

Resistant Dextrins as Prebiotic

Compression, supramolecular organization and free radical polymerization of ethylene gas

At low pressure, ethylene gas consists of single translating and rotating molecules and behaves as an ideal gas. With decrease of free volume by compression, various rotating supramolecular particles are formed, which require less space for the movement: molecular pairs, bimolecules and oligomolecules. The appearance of a new kind of particles is manifested as a phase transition of the second o...

Free Radical Scavenging Principles of Salvia reuterana Boiss. Aerial Parts

Salvia reuterana Bioss. is an aromatic perennial plant traditionally used for its anxiolytic and sedative properties. In the present study, various fractions and essential oil of S. reuterana aerial parts were investigated to find its free radical scavenging principles. Hydroalcoholic fraction with IC50 value of 112.6 ±3.2 μg ml-1 in DPPH assay demonstrated the highest free radical scavenging a...
