A database for evaluating the toxicological risk of pesticides.
This study of Overtox-DB, a computerized database for managing chemical toxicity data, is a product of the application of typical methodologies regarding information science and computer technology. The methodology applied can be reduced to three-basic elements: the collection of requirements, design, and achievement. Overtox-DB was developed by defining technological elements for managing data and its structure and by identifing the procedures and methodologies for data storage, retrieval, distribution, and standardization of many kinds of test data stored in the same format. The program stores data about chemical identification, physical and chemical properties, toxicological tests, mutagenicity, teratogenicity, carcinogenicity, and a bibliography of chemical compounds. Overtox-DB consists of five modules: experimental and bibliographic, data collection, molecular data collection, data search, and data report. The Overtox-DB user responds to a simplified set of query commands and boolean operators that interact with the system to retrieve different toxicological data (the majority of fields are defined as search fields and identify the test system, results of the assays, administration route, dose, etc.). The collected information provides an analytical characterization of biological activities for many compounds and identifies evidence possibly lacking in experimental approaches. Indeed, this database could permit a comparative evaluation with other substances and can be used for structure-activity relationship studies.

Structuring strain data for storage and retrieval of information on fungi and yeasts in MINE, the Microbial Information Network Europe.
A distributed Microbial Information Network Europe (MINE) is being constructed by a number of major microbial culture collections in countries of the European Community, with the support of the Biotechnology Action Programme (BAP) of the Commission of the European Community. The representatives of the collections participating in MINE have agreed to adopt a general format for the computer storage and retrieval of strain data. This uniform format will facilitate the electronic combination and exchange of data from different collections in order to produce integrated catalogues and the use of identical commands to search the different databases. It is recommended to other collections who may wish to contribute data to the MINE network or between themselves. Three kinds of records can be linked to the leading 'species records': strain records, synonym records, and alternative morphonym records. A minimum data set of 30 fields (similar to the fields used for producing catalogues) is defined that facilitates the exchange of data between the national nodes and serves as a directory to strains available at other nodes. It is suggested that the full strain record comprise 99 fields, grouped in 12 blocks: internal administration--name--strain administration--status--environment and history--biological interactions--sexuality--properties (cytology, biomolecular data)--genotype and genetics--growth conditions--chemistry and enzymes--practical applications. Several fields are divided into subfields of different ranks. Delimiters are used either to separate a range of entries that have to be indexed or to divide an entry from the reference to its source or remarks that should not be indexed. The contents and structure of the fields proposed for filamentous fungi and yeasts are described and in some cases illustrated by examples. Uniformity of input is essential for indexed fields and desirable for non-indexed fields. Seven thesaurus files are envisaged to ensure consistency.

Microcomputer-based programs for the practicing vascular surgeon.
An inexpensive microcomputer system can be programmed in BASIC to provide convenient data storage, retrieval, and analysis for the practicing vascular surgeon. A personalized registry program permits input of key patient data that can be processed and retrieved in list form or groupings with operator control of variables. A second program, in which lower extremity revascularization procedures can be analyzed by various parameters, is described. Results can be obtained in life-table formats with comparative statistical analysis. For the private practitioner of vascular surgery, the use of various computer programs will allow management of information for self-assessment, record keeping, teaching, and publication with great accuracy and at significant cost savings. In addition, word processing can increase secretarial output and efficiency. Office management programs are available but need to be individually investigated to determine their use for a particular practice. The major advantages of the microcomputer for the practicing vascular surgeon are personal control and ready access to data that are easy to store, analyze, and retrieve.

Review of epidemiology in clinical cardiology.
The application of epidemiological techniques to clinical cardiology has led to very significant advances in the diagnosis and treatment of coronary atherosclerosis. However, these epidemiological techniques almost necessitate the use of modern computer technology, including data base management systems, in the application of which medicine has lagged behind other areas. Businessmen have come to rely on computerized methods of data storage, retrieval, and analysis to sell commercial products and manage our finances--while their medical counterparts rely on imcomplete data in forgetful minds beset with bias and emotion to use powerful therapeutic tools in the treatment of patients. Hopefully, the next decade will see a new generation of clinical researchers who will combine epidemiology and computer technology for the improvement of health care delivery.

Hopper: software for automating data tracking and flow in DNA sequencing.
MOTIVATION: Genome-scale DNA sequencing is a multistep process in which large numbers of small template clones are propagated, purified, sequenced and analyzed on acrylamide gels. A significant challenge to these projects is the scale at which the data handling must be done. Hence, large-scale sequencing facilities will benefit from tracking template DNA information (purification methods, reaction and electrophoresis conditions) in a systematic fashion. A lack of software tools that support automated sample entry, and automatic data storage, retrieval and analysis are a major hindrance to recording and using laboratory workflow information to monitor the overall quality of data production. RESULTS: The UNIX file system has been used to prototype automation of the flow of data from the ABI sequencer to a data repository. Data are automatically processed by a central Perl program, Hopper, which runs a series of programs that analyze data quality (read length estimate, fraction of indeterminate bases, and number of contaminating and repetitive sequences), assemble shotgun sequence data, and generates simple reports describing the results.

Analysis of beat-to-beat cardiovascular hemodynamic variables obtained from long-term biotelemetry.
Manual methods of large volume data storage, retrieval, and analysis are difficult, time consuming, and present numerous opportunities for calculation errors. We have designed and implemented a comprehensive computer-based system for performing these functions. Development of this system was necessary since left ventricular (LV) blood pressure and two regional LV wall thickness measurements were obtained during long-term extracorporeal biotelemetry of miniswine for 24-h periods. During a single recording period over 100,000 individual cardiac cycles were recorded on analog tape and later analysed for determination of global myocardial oxygen demand and regional myocardial function. In addition, custom designed software was developed to determine the extent and duration of myocardial dysfunction. Batch file commands enabled the customized software to operate without prompting by the user thus optimizing the time usage of the computer, and the computer based data acquisition and analysis system. Although this system was designed specifically for analysing cardiovascular hemodynamic variables, it is flexible and can be applied to other experimental applications.

Benefits and lessons learned from stored electrogram information in implantable defibrillators.
Implantable defibrillators have evolved from simple event counters to sophisticated diagnostic monitoring units capable of storing electrocardiographic information surrounding arrhythmia events and device therapy. In this review, the nature and characteristics of these stored electrocardiographic recordings are discussed and examples displayed. Potential benefits and limitation of stored electrogram analysis are described with respect to both clinical utility and the ability to enhance our understanding of ventricular arrhythmogenesis. Finally, future developments to improve data storage, retrieval, and analysis are identified.

The O.M.E.N.S. classification of hemifacial microsomia.
The wide spectrum of anomalies associated with hemifacial microsomia (HFM) has made systematic and inclusive classification difficult. We propose a nosologic system in which each letter of the acronym O.M.E.N.S. indicates one of the five major manifestations of HFM. O for orbital distortion; M for mandibular hypoplasia; E for ear anomaly; N for nerve involvement; and S for soft tissue deficiency. The O.M.E.N.S. system is easily adapted for data storage, retrieval, and statistical analysis. A retrospective study of 154 patients with HFM classified according to the O.M.E.N.S. system confirmed the concept that the mandibular deformity is the cornerstone of the anomaly. Statistical analysis demonstrated a positive association between mandibular hypoplasia and the severity of orbital, auricular, neural, and soft tissue involvement. This study did not confirm a previously reported predominance of gender or sidedness. Analysis of statistical correlations failed to substantiate a Goldenhar variant as a syndromic entity. Our analysis showed that palatal deviation is probably caused by muscular hypoplasia and not by weakness of a particular cranial nerve.

The management of information: storage and retrieval of data.
Internationally harmonized and cost-effective control of chemicals marketed worldwide greatly depend both on the generation of and easy access to reliable and comparable experimental information. Stored data are of use only if information can be retrieved quickly in an understandable form. Some models and theories of information retrieval (e.g. fuzzy set theory, probabilistic approach, artificial intelligence) are briefly discussed first, then followed by applications (such as indexing and clustering techniques). Finally the structure of databases is briefly reviewed.

[Copyright and natural sciences].
Works in the natural sciences are provided with comparatively less copyright protection than literary works. Nevertheless, this protection is important for scientists. However, more recently, modern methods and techniques of information and documentation, such as reprography, microfilm archives, electronic data storage and retrieval, and data transmission have questioned the justification and effectiveness, even in principle, of this protection. A more detailed analysis demonstrates that this involves not so much a crisis of copyright law as a crisis of the entire field of scientific information.

Computer processing of visual field data. I. Recording, storage, and retrieval.
A minicomputer system has been developed to provide real-time management of visual field data. Records of a large population of patients with glaucoma in a university ophthalmic practice are stored on magnetic disks. Data storage has been semiautomated by means of a microprocessor-controlled recording device for standard perimeters. Existing visual field records may also be digitized by means of a magnetic graphics tablet. Records are retrievable in real time and are graphically displayed at video terminals.

A knowledge-based information system for monitoring drug levels.
The expert system shell SMR has been enhanced to include information system routines for designing data screens and providing facilities for data entry, storage, retrieval, queries and descriptive statistics. The data for inference making is abstracted from the data base record and inserted into a data array to which the knowledge base is applied to derive the appropriate advice and comments. The enhanced system has been used to develop an intelligent information system for monitoring serum drug levels which includes evaluation of temporal changes and production of specialized printed reports. The module for digoxin has been fully developed and validated. To demonstrate the extension to other drugs a module for phenytoin was constructed with only a rudimentary knowledge base. Data from the request forms together with the S-digoxin results are entered into the data base by the department secretary. The day's results are then reviewed by the clinical pharmacologist. For each case, previous results may be displayed and are taken into account by the system in the decision process. The knowledge base is applied to the data to formulate an evaluative comment on the report returned to the requestor. The report includes a semi-graphic presentation of the current and previous results and either the system's interpretation or one entered by the pharmacologist if he does not agree with it. The pharmacologist's comment is also recorded in the data base for future retrieval, analysis and possible updating of the knowledge base. The system is now undergoing testing and evaluation under routine operations in the clinical pharmacology service. It is a prototype for other applications in both laboratory and clinical medicine currently under development at Uppsala University Hospital. This system may thus provide a vehicle for a more intensive penetration of knowledge-based systems in practical medical applications.
