| within | 1. In the inner or interior part of; inside of; not without; as, within doors. "O, unhappy youth! Come not within these doors; within this roof The enemy of all your graces lives." (Shak) "Till this be cured by religion, it is as impossible for a man to be happy that is, pleased and contented within himself as it is for a sick man to be at ease." (Tillotson) 2. In the limits or compass of; not further in length than; as, within five miles; not longer in time than; as, within an hour; not exceeding in quantity; as, expenses kept within one's income. "That he repair should again within a little while." "Within these five hours lived Lord Hastings, Untainted, unexamined, free, at liberty." (Shak) 3. Hence, inside the limits, reach, or influence of; not going outside of; not beyond, overstepping, exceeding, or the like. "Both he and she are still within my power." (Dryden) "Within himself The danger lies, yet lies within his power." (Milton) "Were every action concluded within itself, and drew no consequence after it, we should, undoubtedly, never err in our choice of good." (Locke) Origin: OE. Withinne, withinnen, AS. Wioinnan; wio with, against, toward + innan in, inwardly, within, from in in. See With, In. Source: Websters Dictionary (01 Mar 1998) |
| anti-allergic and respiratory system agents | A collective term for drugs used to treat allergic reactions as well as those drugs that produce an effect on the respiratory system. (12 Dec 1998) |
| respiratory system | The organs that are involved in breathing. These include the nose, throat, larynx, trachea, bronchi, and lungs. (12 Dec 1998) |
| respiratory system abnormalities | Congenital structural abnormalities of the respiratory system. (12 Dec 1998) |
| respiratory system agents | Drugs used for their effects on the respiratory system. (12 Dec 1998) |
| diagnostic techniques, respiratory system | Methods and procedures for the diagnosis of diseases of the respiratory tract or its organs. It includes respiratory function tests. (12 Dec 1998) |
| attachment sites | <microbiology, molecular biology> Particular loci in both bacterial and phage DNA molecules at which phage DNA is integrated into the bacterial DNA by recombination between these sites. (12 Dec 1998) |
| binding sites | The reactive parts of a macromolecule that directly participate in its specific combination with another molecule. (12 Dec 1998) |
| binding sites, antibody | Local surface sites on antibodies which react with antigen determinant sites on antigens. They are formed from parts of the variable regions of the fab fragment of the immunoglobulin. (12 Dec 1998) |
| chromosome fragile sites | Heritable sensitive regions of chromosomes which show up in vitro as non-staining bands. They are associated with chromosome breakage and other aberrations, and, when located on sex chromosomes, they produce phenotypic abnormalities. No abnormal phenotype has been definitely identified with autosomal fragile sites, but some rare autosomal recessive disorders may be due to homozygosity for fragile sites. Fragile sites are designated by the letters "fra" followed by the designation for the specific chromosome and locus. (12 Dec 1998) |
| contact sites A | Developmentally regulated adhesion sites that appear on the ends of aggregation competent Dictyostelium discoideum at the stage when the starved cells begin to come together to form the grex. Originally detected by the use of Fab fragments of polyclonal antibodies, raised against aggregation competent cells and adsorbed against vegetative cells, to block adhesion in EDTA containing medium. (Cell cell adhesion mediated by contact sites A, unlike that mediated by contact sites B, is not divalent cation sensitive). The fact that a mutant deficient in csA behaves perfectly normally in culture is puzzling. (18 Nov 1997) |

| crohn disease: sites | <radiology> Oesophagus: rare, stomach (2-20%): granulomatous gastritis, pseudo-post Bilroth-I appearance, ramshorn sign, antral-duodenal fistula, duodenum (4-10%): almost always associated with gastric involvement, bulb and proximal half of duodenum, small bowel (80%): regional enteritis, terminal ileum (alone/in combination): 95%, jejunum/ileum: 15%, commonly associated with medial caecal defect, colon (22-55%): granulomatous colitis, particularly on the right side, transverse stripe sign: contrast within coarse mucosal folds, rectum (35-50%) see: Crohn disease (12 Dec 1998) |
| sequence tagged sites | Short, tagged tracts of DNA sequence that are used as landmarks in genome mapping. In most instances, 200 to 500 base pairs of sequence define a sequence tagged site (sts) that is operationally unique in the human genome (i.e., can be specifically detected by the polymerase chain reaction in the presence of all other genomic sequences). The overwhelming advantage of stss over mapping landmarks defined in other ways is that the means of testing for the presence of a particular sts can be completely described as information in a database.
