The role of the World Reference Laboratories for Foot-and-Mouth Disease and for Rinderpest.

The World Reference Laboratories for Foot-and-Mouth Disease and for Rinderpest provide a worldwide diagnostic and surveillance service for these disease for FAO and OIE. Both laboratories are housed within the high security facility of the Institute for Animal Health, Pirbright, UK. Foot-and-mouth disease (FMD) and rinderpest (RP) are OIE List A diseases and historically have caused huge losses to agricultural economies around the world, prompting the establishment of veterinary colleges in Europe and environmentally controversial control programs in Africa. FMD and RP have now been geographically restricted, but the large legal and illegal world trade in live animals and animal products constantly threatens to allow them to spread back into disease-free areas. The Reference Laboratories provide a center of excellence for the development of improved diagnostic techniques and a repository of isolates collected over many years. These libraries provide material for investigations of the molecular epidemiology and evolution of the viruses and a data base against which new isolates can be compared. Thus it is possible to individually characterize new outbreak strains, identify their likely origin and provide the most up-to-date support for their control.

The organization and distribution of patient education materials in family medicine practices.

BACKGROUND: Millions of dollars are spent annually on the production and distribution of patient education materials; however, there are no studies describing their actual use by physicians. Using qualitative data from a large comparative case study, our analysis evaluates how patient education materials are organized and used in family practices. METHODS: Eighteen purposefully selected family medicine practices were directly observed for 4 to 12 weeks each. A total of 57 providers were shadowed by a research nurse, and detailed field notes on 1600 patient encounters were recorded. A 3-member analysis team reviewed the qualitative data and identified emergent patterns. RESULTS: Clinics' use of patient education materials fell mostly into 2 distinct patterns. "Stockpilers" were providers who relied on the clinic staff to develop and organize a common library of patient education handouts. Providers with a "personal stash" collected much smaller numbers of materials that they personally maintained. Providers in the latter group had a known repertoire of a limited amount of educational material and used it more often than providers with access to a greater variety and number of handouts. In all practices, providers distributed most handouts; staff and self-selection by patients played a minor role. CONCLUSIONS: It appears that provider involvement and familiarity with patient education materials are key to their use in clinical practice. Clinicians use written patient education materials most efficiently by personally selecting and maintaining a small number of handouts that address topics most relevant to their practice.

Sensitivity analysis and other improvements to tailored combinatorial library design

"Tailoring" combinatorial libraries was developed several years ago as a very general and intuitive method to design diverse compound collections while controlling the profile of other pharmaceutically relevant properties. The candidate substituents were assigned to "categorical bins" according to their properties, and successive steps of D-optimal design were performed to generate diverse substituent sets consistent with required membership quotas from each bin. This serial algorithm was expedient to implement from existing D-optimal design codes, but was order-dependent and did not generally locate the very best possible design. A new "parallel" Fedorov search algorithm has now been implemented that can find the most diverse property-tailored design. An ambiguous mass penalty has been added, whereby most duplicate masses can be eliminated with little loss of library diversity. Sensitivity analysis has also been added to quantitatively explore the diversity trade-offs due to increasing or decreasing each specific kind of bias.

The National Library of Medicine. Evolution of a premier information center.

From a small collection of medical publications in the Surgeon General's Office in 1836, the National Library of Medicine has developed into the leading repository of medical information in the world. Despite strong opposition and impediments from certain quarters, involving considerable machinations and intrigue, the determination of interested medical leaders and sympathetic members of Congress triumphed in having this remarkable institution established on the campus of the National Institutes of Health, Bethesda, Md. As a participant in many of the negotiations preceding that decision, I have happily witnessed the transformation of the Library, long housed in cramped, makeshift quarters, to its present magnificent structures in the heart of our nation's foremost medical research center. Its prodigious collection of print, audiovisual, and electronic information; its imaginative research projects; its excellent outreach program; and its innovative services and products are indispensable to all practicing health professionals, scientists, and medical educators, as well as to journalists, government officials, and others. The ultimate beneficiary, of course, is the patient.

The history of medical libraries from 2000 B.C. to 1900 A.D.

Tablets said to date back to 2000 b.c. represent the earliest medical writings so far discovered. The history of the medical library (defined as a place where a collection of medical writings is kept) is traced through ancient and medieval civilizations, and the dependence of advancement or decline on the attitude toward learning and knowledge is demonstrated.The change in structure of medical libraries that took place around the 1500s with the development of scientific societies is discussed. Medical libraries of Colonial America are described and the history is brought forward to the era of public library collections of medical material in the early 1900s.

Sensory organization of the human thalamus.

A computerized program has been developed for on-line display and tape-library storage of stimulation-mapping data collected during stereotactic procedures. Using computer-generated displays of pooled clinical physiological data it has been possible to map through the upper midbrain and thalamus the lemniscal, spinoquintothalamic, auditory, vestibular, visual, extrapyramidal, and motor pathways, as well as the location of the pia. Each system is recognizable by a stereotyped, artificial, somatotopically organized stimulation-induced response that is devoid of modality information and independent of the site and parameters of stimulation.

Basic reference aids for small medical libraries.

Selected primarily for the small medical library, this list is compiled to serve as a practical guide for the librarian in developing and utilizing an effective reference collection. Arrangement is by broad subject groups; titles chosen are chiefly in English with geographic coverage limited to the United States and Canada. Texts in subject fields have been omitted since these are adequately covered in several comprehensive guides to the literature.

Analysis of reference transactions using packaged computer programs.

Motivated by a continuing education class attended by the authors on the measurement of reference desk activities, the reference department at Scott Memorial Library initiated a project to gather data on reference desk transactions and to analyze the data by using packaged computer programs. The programs utilized for the project were SPSS (Statistical Package for the Social Sciences) and SAS (Statistical Analysis System). The planning, implementation and development of the project are described.

The consequences of offering fee-based services in a medical library.

Fee-based services may influence, both subtly and dramatically, the operation of a medical library. Fears that have been raised about the consequences of fee-based services are recalled and applied to the context of medical librarianship. Specifically covered are the effects of fee-based services on service to traditional user groups, collection development, interlibrary cooperation, and management style. The discussion includes references to the program of fee-based services offered by the New York Academy of Medicine Library.

Creating the library itself: collection, staff, and space.

It is stressed that many points must be settled between the librarian and the planners. Relationships between the library and the medical school and the university library should be made clear. The librarian must be intimately involved with the architect, with the selection of faculty, and with the planning of curriculum. Consideration is given to problems of collection building in the areas overlapping with other institutions and of journal collections. Cataloging is considered, and the need to develop accounting procedures.

Developing multidisciplinary library services in trust hospitals: a case study at the City Hospitals Sunderland NHS Trust.

The paper describes an example of good practice in the establishment of multidisciplinary library services at a Trust hospital. In 1995, City Hospitals Sunderland NHS Trust commissioned a survey to determine their needs for library services for all staff. The results of the survey and the recommendations are described. The Trust's further actions are briefly noted. This case study is set into the wider context of the need for well-resourced library and information services within the NHS. The constraints under which such developments operate are listed.

Identification of receptor ligands by screening phage-display peptide libraries ex vivo on microdissected kidney tubules.

A novel method to identify receptor ligands for defined renal tubular segments has been developed. Ex vivo screening of phage-display peptide libraries on isolated intact rat proximal convoluted tubules (PCT) and cortical collecting ducts (CCD) allowed the direct access of phage to the basolateral surface of tubular epithelial cells. Two distinct peptide motifs were selected for CCD and PCT, indicating differential expression of some membrane receptors on the basolateral surface of defined kidney tubule segments. Using the linear peptide motif ELRGD(R/M)AX(W/L), recovered from freshly isolated rat CCD, mediated 16-fold selectivity of phage binding to CCD compared with PCT. Binding to CCD was 39-fold higher than that of a random control phage. Binding and subsequent internalization of phage, most likely by an integrin-mediated endocytosis pathway, was abolished by the addition of the corresponding synthetic peptide. Furthermore, the results demonstrate that presentation and flanking amino acids determine the specific binding properties of RGD ligands to their putative integrin receptors. The results emphasize the need of a native cell system for the identification of renal epithelial cell surface ligands. Such ligands are of potential relevance for the analysis of interactions between extracellular matrix and kidney tubules or for the development of improved vectors for kidney-specific drug delivery or gene transfer.

The combinatorial library: a multifunctional resource.

About 10 years ago Dr. Mario Geysen introduced a method for synthesizing a large number of peptides on solid supports simultaneously. This work has subsequently been generalized by many other research groups to develop technologies that allow from hundreds to thousands to millions of compounds to be synthesized in parallel. These large collections of compounds have been now termed combinatorial libraries. Much of the effort in this field has been directed to drug discovery. However, in recent years, these libraries have been shown to be very useful for finding compounds (such as inhibitors, binding agents, enzymes, and antibodies) that satisfy specific requirements. Thus these techniques represent a very excellent resource for the discovery of compounds for a variety of biotechnological process needs.

Inference and visualization of complex genotype-phenotype maps with gpmap-tools.

Understanding how biological sequences give rise to observable traits, that is, how genotype maps to phenotype, is a central goal in biology. Yet our knowledge of genotype-phenotype maps in natural systems is limited due to the high dimensionality of sequence space and the context-dependent effects of mutations. The emergence of Multiplex assays of variant effect (MAVEs), along with large collections of natural sequences, offer new opportunities to empirically characterize these maps at an unprecedented scale. However, tools for statistical and exploratory analysis of these high-dimensional data are still needed. To address this gap, we developed gpmap-tools (https://github.com/cmarti/gpmap-tools), a python library that integrates a series of models for inference, phenotypic imputation, and error estimation from MAVE data or collections of natural sequences in the presence of genetic interactions of every possible order. gpmap-tools also provides methods for summarizing patterns of epistasis and visualization of genotype-phenotype maps containing up to millions of genotypes. To demonstrate its utility, we used gpmap-tools to infer genotype-phenotype maps containing 262,144 variants of the Shine-Dalgarno sequence from both genomic 5'UTR sequences and experimental MAVE data. Visualization of the inferred landscapes consistently revealed high-fitness ridges that link core motifs at different distances from the start codon. In summary, gpmap-tools provides a flexible, interpretable framework for studying complex genotype-phenotype maps, opening new avenues for understanding the architecture of genetic interactions and their evolutionary consequences.

Building an archives in a medical library.

In 1979 the University of Medicine and Dentistry of New Jersey established an archives to collect, preserve, and retrieve important documentation related to its history. This paper examines various steps in building an archives and the development of a coherent collection policy, including potential sources for archival material. Problems and possible solutions concerning what to preserve from the vast quantities of material generated by an institution are considered. The relationship between the archives and the medical library and the requirements of the physical plant are discussed, including the storage and preservation of materials.

Faxon Finder/Faxon Xpress: report from a beta test site.

In this environment of expanding information needs, spiraling journal costs, and curtailed financial resources, medical libraries must take advantage of the rapid evolution in document delivery services. There are exciting developments in transmission technology, from fax machines to scanners to the Internet. There is also a notable shift away from the traditional reliance on library networks toward use of commercial vendors as document providers. These changes require reevaluation of interlibrary loan (ILL) and document delivery systems on many levels, including pricing structures, work flow, and impact on collection development. As commercial vendors develop increasingly effective products, librarians can test, evaluate, and incorporate them into their ILL operations to enhance service to users and relieve the pressure to acquire new resources; in this way, librarians can move from the "just in case" practice of building an on-site collection to the "just in time" model of providing timely delivery of materials to users as needed. This paper describes a beta test of the Faxon Finder/Faxon Xpress table of contents and document delivery services conducted by the Treadwell Library of the Massachusetts General Hospital.
