Summary
The increasing volume of medical literature necessitates efficient search methods. New search engine strategies and the World Wide Web (WWW) offer improved access and precision for medical information retrieval.
Area of Science:
- Medical Informatics
- Information Science
Background:
- The exponential growth of published medical information over 30 years has created a critical need for advanced search strategies.
- Current MEDLINE searches, relying on keywords and abstracts with Boolean operators, often yield overwhelming results.
Purpose of the Study:
- To explore efficient methods for searching the expanding body of medical literature.
- To examine the evolution and effectiveness of World Wide Web (WWW) search tools for accessing medical information.
Main Methods:
- Analysis of traditional keyword and abstract searching limitations.
- Evaluation of World Wide Web (WWW) cataloging strategies: directories versus search engines.
- Discussion of advanced search refinements like phrase searching and proximity operators.
- Consideration of emerging search engine types and future conceptual searching.
Main Results:
- Keyword and textword searches on full-text articles can be voluminous.
- Search engines and directories offer distinct approaches to WWW information retrieval.
- Advanced search techniques (phrase, proximity) and specialized search engines improve search precision.
- The lines between directories and search engines are blurring, with metasearch sites emerging.
Conclusions:
- The development of the Internet and WWW enables unprecedented access to medical information.
- Refined search engine functionalities and specialized tools are crucial for efficient medical literature retrieval.
- Future conceptual searching promises more intuitive information discovery, shifting focus from search mechanics to results.

02:02Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
02:47Protein Families
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key locations, protein...
02:04Protein-protein Interfaces
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...
02:26Protein Networks
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:41Signal Sequences and Sorting Receptors
Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...
