  • This is an insider's account of 50 years of genetic studies of the soil-inhabiting microbes that produce most of the antibiotics used to treat infections, as well as anti-cancer, anti-parasitic and immunosuppressant drugs. The book begins by describing how these microbes - the actinomycetes - were discovered in the latter part of the nineteenth century, but remained a 'Cinderella' group until, in the 1940s, they shot to prominence with the discovery of streptomycin, the first effective treatment for tuberculosis and only the second antibiotic after penicillin to become a medical marvel.

  • Hospitals, by their very nature, are dangerous places. Sick and infected patients are clustered together in one institution, often in close proximity to those who are immunosuppressed due to recent surgery, chemotherapy or transplantation. Contact between these various patient groups is easily achieved via the hands of healthcare workers (HCWs), use of shared equipment or the hospital’s air handling system.

  • UDP-N-acetylglucosamineenolpyruvyl transferase (MurA), catalyzes the first step in the biosynthesis of peptidoglycan, involving the transfer of the intactenolpyruvyl moiety from phosphoenolpyruvate to the 3¢-hydroxyl group of UDP-N-acetylglucosamine (UDPNAG). The enzyme is irreversibly inhibited by the antibiotic fosfomycin. The inactivation is caused by alkylation of a highly conserved cysteine residue (C115) that participates in the binding of phos-phoenolpyruvate.

  • Basidiomycetes constitute a natural source of biologically active metabolites. Many basidiomycetes have been classified by the National Cancer Institute of the United States as antitumor agents exhibiting an immunomodulatory activity.1 The therapeutic activity is mainly related to polysaccharides or protein-bound polysaccharides, such as glucans, heterogalactans, and glucanproteins, which are present either in the mycelium or in the fruit body.2–6 Among these polysaccharides are b-D-glucans, which are of particular interest because of their pharmacological properties.

  • European society and the European economy do not yet exploit the full potential for resource efficiency. Much recyclable waste is either exported or sent to landfill. A lack of long-term frameworks holds back planning and investment, most obviously on a climate and energy framework beyond 2020, but also on long term sustainable use of key resources such as air, soil, energy, water, fish and biomass. At the same time, such frameworks can help to galvanise the innovation needed to exploit the potential of the transition to a low-carbon economy in areas like transport, energy and agriculture....

  • We ¯nd that when the hypothetical benchmarks are recognized as being unavailable for investment, there need not exist close substitutes for them in the universe of mutual funds. For an investor who believes completely in the accuracy of the Fama-French model and precludes managerial skill, the perceived maximum Sharpe ratio is only 66 percent of what could be achieved by direct investment in that model's benchmarks. For a believer in the Carhart four-factor model, the corresponding value is 54 percent.

  • As the Basel Committee on Banking Supervision has pointed out, it has become increasingly important to look beyond the traditional earnings and economic value effects and assess indirect interest rate effects as well. Taking a broader view of the potential earnings impact of changing interest rates, banks also need to take into consideration the growing share of (interest-sensitive) fee- based fi nancial services (loan servicing, asset securitization programs, pay- ments etc.).

  • The best practice today is to read data into the SAS environment for processing. For highly repeatable processes, this might not be efficient because it takes time to transfer the data and resources are used to temporarily store in the SAS environment. In some cases, the results of the SAS processing must be transferred back to the DBMS for final storage, which further increases the cost. Addressing this challenge can result in improved resource utilization and enable companies to answer business questions more quickly. ...

  • For the last 60 or so years the chemotherapy of bacterial infections has been dominated by natural products and their semi-synthetic variants. Although the term antibiotic was initially used exclusively to describe those anti-bacterials of natural or semi-synthetic origin, it has become broadened in common usage to include antibacterial agents of purely synthetic origin as well. The emphasis of this chapter will be on the discovery of novel prototype structures that represent the different classes of antibiotic e.g.

  • The second set of assumptions is contained in the firm’s marketing model. This contains managers’ analysis of which customers the firm can most profitably target and knowledge about what their wants are. It also contains the analysis of the competition: what strategies competitors are likely to follow, what their strengths and weaknesses are, and what capabilities are needed to create a competitive advantage. Next is the operations model, which contains the analysis of the best way to structure the firm’s value chain to produce and deliver products and service to customers.

  • A database is any collection of related data. The files on your hard drive and the piles of paper on your desk all count as databases. What distinguishes a relational data- base from other kinds of databases is the mechanism by which the database is orga- nized—the way the data is modeled. A relational database is a collection of data organized in accordance with the relational model to suit a specific purpose. Relational principles are based on the mathematical concepts developed by Dr. E. F.

  • The Acutely Ill Patient: Treatment In the acutely ill patient, empirical antibiotic therapy is critical and should be administered without undue delay. Increased prevalence of antibiotic resistance in community-acquired bacteria must be considered when antibiotics are selected. Table 115-1 lists first-line treatments for infections considered in this chapter. In addition to the rapid initiation of antibiotic therapy, several of these infections require urgent surgical attention.
