Selected Medical Applications

Selected physical properties of oxygen are included in Table 9.24. It is a colourless, odourless and tasteless gas which is essential for life and considered to be non-toxic at atmospheric pressure. It is somewhat soluble in water and is slightly heavier than air. Important uses are in the steel and glass industries, oxyacetylene welding, as a chemical intermediate, waste-water treatment, fuel cells, underwater operations and medical applications. 

VI. SELECTED EXAMPLES OF POTENTIAL MEDICAL APPLICATIONS OF LIPOSOMES... 

Interferons represent an important family of biopharmaceutical products. They have a proven track record in the treatment of selected medical conditions, and their range of clinical applications continues to grow. It is also likely that many may be used to greater efficacy in the future by their application in combination with additional cytokines. 

Meanwhile other experiments have been carried out to isolate DNA molecules with either RNA- or DNA-phosphoesterase activity [69-71,142,143]. Since Mg +-dependent rather than Pb +-dependent cleavage is compatible with intracellular conditions and thus, more suitable for possible medical applications, deoxyribozymes were selected that used Mg + instead of Pb for cleavage [112]. One optimized deoxyribozyme that emerged in this selection showed a cleavage rate of 0.01 min and was also capable of intermolecular cleavage. 

In a review on the design of ligands for selective complexation of metal ions in aqueous media and a book on the principles underlying stability constants and on the design of metal complexes for various medical applications iron complexes and their solution chemistry take their appropriate place. 

For medical applications, the antioxidant is selected from ascorbic acid, propyl gallate, butylhydroxyanisole, or dibutylhydroxy-toluene (58). 

For these oligosaccharide-containing pharmaceutics ment in medical applications are given. The key probli of selectively adjusted methods will be addressed. 

Colorant systems to be used in food contact, cosmetics, toys, pharmaceutical, and medical applications fall under various governmental regulations. The colorist needs to be familiar with these regulations and select colorants accordingly. Also, some states regulate the use of heavy metal pigments in packaging applications.
