Anatomy, Comparative definition: The comparative study of animal structure with regard to homologous organs or parts. (Stedman, 25th ed)
Comparative Study definition: Comparison of outcomes, results, responses, etc for different techniques, therapeutic approaches or other inputs.
Histology, Comparative definition: The study of the similarities and differences in the structures of homologous tissues across various species.
Physiology, Comparative definition: The biological science concerned with similarities or differences in the life-supporting functions and processes of different species.
Psychology, Comparative definition: The branch of psychology concerned with similarities or differences in the behavior of different animal species or of different races or peoples.
Comparative Genomic Hybridization definition: Comparative genomic hybridization (CGH) is a technique that allows the detection of losses and gains in DNA copy number across the entire genome without prior knowledge of specific chromosomal abnormalities. Comparative genomic hybridization utilizes the hybridization of differentially labeled tumor and reference DNA to generate a map of DNA copy number changes in tumor genomes. Comparative genomic hybridization is an ideal tool for analyzing chromosomal imbalances in archived tumor material and for examining possible correlations between these findings and tumor phenotypes. (from Ried et al. J Mol Med 1997 75:801-14)
comparative genomic hybridization definition: technique which produces a map of DNA sequence copy number as a function of chromosomal location throughout the entire genetic genome, and allows the detection of genetic deletions, duplications, and amplifications.
Comparative Genomic Hybridization definition: A method for analyzing and mapping differences in the copy number of specific genes or other large sequences between two sets of chromosomal DNA. It is used to look for large sequence changes such as deletions, duplications, or amplifications within the genomic DNA of an individual (with a tumor for example) or family members or population or between species.
Comparative Biochemistry definition: The study of the similarities and differences between different living organisms of the biological and physiological chemistry of the organisms. Used for the scientific discipline or the biochemical processes themselves. (from PSY94)
Comparative Biology definition: Biological field of study concerned with the analysis of similarities and differences in specific traits between different species.
Comparative Carcinogenesis definition: The study of the similarities and differences between different living organisms of the process by which normal cells are transformed into cancer cells.
Comparative Pathology definition: Biological field of study concerned with the analysis of similarities and differences in specific characteristics between different diseases.
Molecular Microarrays, Comparative Genomic definition: Microarrays designed to detect genomic gains or losses or changes in the number of copies of a particular gene associated with a disease. The packet samples on the microarray spots consist of large immobilized pieces of DNA with a known chromosomal location for each spot. DNA-labeled samples from normal and diseased tissues are hybridized to the array; an expression pattern with more bright spots indicates that the number of genes involved in the disease has increased. Expression pattern comparative genomic molecular microarrays can be used to determine the extent and/or follow the progress of particular diseases (e.g., cancer tumors).
Comparative Marker Selection definition: An algorithm for assigning significance values to genes being tested for their ability to discriminate between microarray samples.
Comparative Effectiveness Research definition: Conduct and synthesis of systematic research comparing interventions and strategies to prevent, diagnose, treat, and monitor health conditions. The purpose of this research is to inform patients, providers, and decision-makers, responding to their expressed needs, about which interventions are most effective for which patients under specific circumstances.
