Abstract

There is now a staggering amount of consumer health information relating to cancer available and accessible on the World-Wide Web (WWW or Web). The sheer quantity of information can sometimes make it difficult to locate the best sites for one's needs. The purpose of this article is to point out some of the more useful sites for obtaining cancer information and to highlight their special features. The WWW cancer resources are grouped into five sections: I. Major Sites; II. Sites for Specific Types of Cancer; III. Other Useful Sites; IV. Guides; and V. Collections.  相似文献

The emergence of pathogens resistant to currently available treatments is seen as a public health crisis. Since few new classes of antimicrobial drugs have been developed in the last two decades, it is becoming increasingly probable that healthcare providers will be faced with infections for which no chemotherapeutic agent is available. A renewed emphasis is being placed on employing the most advanced drug discovery technologies in the development of new antimicrobials. The recently introduced technologies of combinatorial chemistry offer new sources of chemical diversity, as well as methods with which to produce and rapidly test them. In the last few years, many groups have adopted a number of approaches in order to apply combinatorial chemistry to antimicrobial drug discovery. These combinatorial strategies, and the manner in which they are used to develop new screening formats or to identify new chemical leads are, reviewed.  相似文献

We present a heterogeneous non-competitive immunological detection assay for peptide and protein antigens from crude extracts of biological sources. This time-resolved fluoroimmunoassay (TR-FIA) has been designed in a solid-phase mode using 96-well microtiter plates. Using the rare-earth metal europium as a fluorescent marker, a highly sensitive, selective and efficient procedure was developed. This technique prevents from interferences of intrinsic protein fluorescence which is highly important for antigen measurement in complex matrices. The TR-FIA has been applied for the detection of circulating forms of the potential anti-tumor agent endostatin, a C-terminal fragment of collagen XVIII, and its close homolog collagen XV (restin) from hemofiltrate. Endostatin was detected with a limit of detection of 3 ng (150 fmol/well) and a broad dynamic range from 10-1000 ng/well.  相似文献

Film-based radiographs are still being used to teach in a conference format, which presents several viewing challenges amongst other problems. In the age of cloud computing, which enables the use of online server storage space, this information could be used more effectively if it were digitized. However, digitizing film-based radiographs and making them available for use in the cloud is not as easy as it seems. In order to address the issue of digitizing the film-based radiograph libraries in our radiology department, we looked at several options. The option that we chose was a consumer-grade scanner, and this decision was based on price, resolution, shades of gray, built-in transparency function, and its physical attributes. Our goal was to digitize the film-based radiograph teaching files so they could be stored in a digital file locker such as Google Picassa for organization and quick access later. These files would constantly be updated in a Google document by residents, and this document would be called the “Living Document” based on its continuous expandability. This method would allow even the smallest radiology department to benefit from the use of modern technology to gain access to valuable information stored in film-based radiographs and give every resident the opportunity to benefit from it.  相似文献
