BACKGROUND: Medical educators bear responsibility for the informational materials that their institutions use to communicate with potential applicants. These documents, because they are often the first official correspondence that prospective students receive, may be influential in shaping students' expectations. METHOD: In March 1990 all North American medical schools that awarded MD or DO degrees were requested to send their catalogs and courses of study to the authors. In response came 175 documents, with nearly all the schools represented at least once. The photographs and other visual images in these documents were then analyzed from the perspective of a hypothetical applicant who perused what his or her initial request for information had produced. RESULTS: Nearly 3,400 images were analyzed and categorized according to content and stylistic approach. Two basic stylistic approaches were found: stylized and documentary. Few documents used exclusively one or the other approach, as the approaches represent poles along a continuum. The stylized approach portrays medical education as a product to be sold, whereas the documentary approach candidly tells the story of medical education. CONCLUSION: The authors conclude that the documentary approach is a more morally responsible way for schools to communicate with individuals who are in the beginning stages of building their mental images of medical education and medical care.
Operators of in-vivo counters often encounter unusual photopeaks, some of which may be attributed to nuclear medicine radiopharmaceuticals recently received by the subject. This article lists the most common radiopharmaceuticals used in nuclear medicine, their common uses, their half-lives and principal decay energies, and the half-lives and decay energies of any contaminants or daughter products they may contain. The purpose is to help the in-vivo counter operator track down and eliminate causes of such unusual photopeaks.
Information technology can be both a vital tool and critical link in the modern public health system. This article discusses the role of information technology in public health and the activities of the Information Technology Collaborative, one of the collaboratives that comprise the national Turning Point initiative. Data are presented from a nationwide survey investigating local health department information technology needs and information technology use. This data, and data from an investigation of state-level public health information technology, will be presented in a more complete format on the Information Technology Collaborative's online Public Health Information Systems Catalog, a free resource for individuals interested in public health informatics. Recommendations for future initiatives, policy changes, and information technology standards are discussed.
When confronted with a novel familial disorder, veterinarians should consult McKusick's catalogue of inherited disorders in humans, called Mendelian Inheritance in Man (MIM), or its online version (OMIM), to see whether a similar disorder has been reported in humans. They should also consult the other readily available sources of comparative information on mice and domesticated species. Increasingly, such consultations can be conducted on the Internet via the World Wide Web. If it is thought that an animal disorder is homologous with a human disorder, publications describing the animal disorder should include the MIM number(s) for that disorder. Future research can then test the hypothesis of homology, until a consensus is reached.

We describe here a systematic approach to the identification of human proteins and protein fragments that can be expressed as soluble proteins in Escherichia coli. A cDNA expression library of 10,825 clones was screened by small-scale expression and purification and 2,746 clones were identified. Sequence and protein-expression data were entered into a public database. A set of 163 clones was selected for structural analysis and 17 proteins were prepared for crystallization, leading to three new structures.
