Development of medications

As research continues into the field of siderophore production and iron uptake, the knowledge gained will be invaluable to the development of medical treatments for bacterial infection,... 

Other frontiers of chemistry take researchers into hidden realms. One of these areas is the human skull, which houses three pounds (1.4 kg) of one of the most complex substances in the universe—the human brain. Chemical investigations of the brain have taken even longer to develop than other fields of chemistry, due to the relative inaccessibility of brain tissue. Yet researchers are making strides in this difficult field, including the development of medications to alleviate disorders such as depression and drug abuse, as explained in chapter 3.

Protein Adsorption. The development of medical implant polymers has stimulated interest in the use of ATR techniques for monitoring the kinetics of adsorption of proteins involved in thrombogenesis onto polymer surfaces. Such studies employ optical accessories in which an aqueous protein solution (93) or even ex - vivo whole blood (94-%) can be flowed over the surface of the internal reflection element (IRE), which may be coated with a thin layer of the experimental polymer. Modem FT-IR spectrometers are rapid - scanning devices, and hence spectra of the protein layer adsorbed onto the IRE can be computed from a series of inteiferograms recorded continuously in time, yielding ah effective time resolution of as little as 0.8 s early in the kinetic runs. Such capability is important because of the rapid changes in the composition of the adsorbed protein layers which can occur in the first several minutes (97). 

Because of the extraordinary supramolecular structure and exceptional product characteristics as high-molecular and high-crystalline cellulosics with a water content up to 99%, nanocelluloses require increasing attention. This review assembles the current knowledge in research, development, and application in the field of nanocelluloses through examples. The topics combine selected results on nanocelluloses from bacteria and wood as well as their use as technical membranes and composites with the first longtime study of cellulosics in the animal body for the development of medical devices such as artificial blood vessels, and the application of bacterial nanocellulose as animal wound dressings and cosmetic tissues. 

Supplementary to the technical use of nano celluloses reviewed in the previous sections, BC in particular has great potential as a natural biomaterial for the development of medical devices and applications in healthcare and veterinary medicine. 

The second chapter by Dieter Klemm, Dieter Schumann, Hans-Peter Schmauder, and coworkers focuses on the recent knowledge of cellulosics characterized by a property-determining supramolecular nanofiber structure. Topics in this interdisciplinary contribution are the types of nanocelluloses and their use in technical membranes and composites as well as in the development of medical devices, in veterinary medicine, and in cosmetics.

Depression is an illness that maims and kills. It kills by suicide and it kills by making medical conditions worse or less responsive to treatment. It maims in the sense that it disables individuals socially and occupationally, causes somatic symptoms itself, and contributes to the development of medical conditions that are disabling. Suicide is a major complication of depression and by no means rare. Approximately one out of seven individuals with recurrent major depression will commit suicide. The large majority—about 70%—are suffering from major depression at the time of the act (Ezzell, 2003).

Substance abuse has been the subject of several lOM studies, which have covered a whole host of issues related to the topic, including federal regulation of methadone treatment, the development of medications for the treatment of opiate and cocaine additions, and community-based research to find better ways to treat people who abuse drugs.
