Life-Science

This biotechnology company has been a partner to researchers engaged in the field of DNA/RNA synthesis by starting as a supplier of high purity products and evolving to an active contract researcher. ChemGenes Corporation has developed its expertise in the field of DNA/RNA synthesis. Both, the reagent products and the specialized custom services are provided, either as services or as a research contractor.

A first example of application of microtomography is taken from life sciences. Here X-ray microscopy and microtomography allows to reconstruct the internal three-dimensional microstructure without any preparation and sometimes even of living objects. Fig. la shows an X-ray transmission microscopical image of bone (femoral head). Several reconstructed cross-sections are shown in Fig.lb. Fig.lc shows the three-dimensional reconstruction of this bone. 

Medline covers primarily biomedical literature, containing more than 13 million citations (October, 2002) of articles from more than 4600 journals published since 1958 [18]. The database covers basic biomedical research, clinical sciences, dentistry, pharmacy, veterinary medicine, pre-clinical sciences, and life science. Medline, a subset of PubMed, is a bibliographic database produced by the US Nationcil Library of Medicine (NLM). The database is available free of charge via SciFinder Scholar or PubMed [19].

Data-Star. This is Europe s leading on-line database service (39) and covers worldwide business news, financial information, market research, trade statistics, business analysis, healthcare / pharmaceuticals, chemicals / petrochemicals, chemical industry, biomedicine /life science, biotechnology, and technology, with an emphasis on Europe. It was originally formed as a joint venture among BRS, Predicasts, and Radio Suisse (the Swiss telecommunications company) (37). Data-Star offers access to about 300 bibliographic, abstract, directory, and fuU-text on-line databases, of which approximately 150 are also available on Dialog (40).

The most important use of diketene is for the preparation of derivatives of acetoacetic acid, such as acetoacetate esters, acetoacetamides, and chloroacetoacetates, which have found many uses in life sciences, dyestuffs, adhesives, and coatings.

The use of radioactive tracers was pioneered by Georg von Hevesy, a Hungarian physical chemist, who received the Nobel Prize in 1943 for his work on radioactive indicators (1). Radioisotopes have become indispensable components of most medical and life science research strategies, and in addition the technology is the basis for numerous industries focused on the production and detection of radioactive tracers. Thousands of radioactive tracers have been synthesized and are commercially available. These are used worldwide in tens of thousands of research laboratories. 

Radioactive tracers account for about 20% of the worldwide market for consumables and reagents for life science research. In 1994 the value was estimated at about 300 million. The principal fuU line manufacturers are Du Pont—NEN Research Products (Boston, Massachusetts) and Amersham International (Amersham, U.K.). These companies share roughly equaHy about 85% of the radiochemicals worldwide market. In addition to an extensive line of catalog products, these suppHers offer custom labeling and custom synthesis services. The rest of the market is shared by producers of a limited range of products or services, such as ICN Biomedicals (Costa Mesa, California) and American Radiolabeled Chemicals (St. Louis, Missouri).

The final section in this volume deals with applications of adhesion science. The applications described include methods by which durable adhesive bonds can be manufactured by the use of appropriate surface preparation (Davis and Venables) to unique methods for composite repair (Lopata et al.) Adhesive applications find their way into the generation of wood products (Dunky and Pizzi) and also find their way into the construction of commercial and military aircraft (Pate). The chapter by Spotnitz et al. shows that adhesion science finds its way into the life sciences in their discussion of tissue adhesives.
