(n.) The science of obstetrics, or midwifery; that department of medicine which treats of parturition.
Example Sentences:
(1) Hexoprenaline is a selective beta 2-mimetic drug used in tocology for the prevention of premature labor and immature birth.
(2) The success rate for hexoprenaline tocolyses is 34-78%, dependent on the initial tocological condition.
Topology
Definition:
(n.) The art of, or method for, assisting the memory by associating the thing or subject to be remembered with some place.
Example Sentences:
(1) The scheme is based on topological information, i.e.
(2) These results provide knowledge of the interrelationships between antibiotic and substrate ribosome binding sites which should eventually contribute to a map of ribosomal topology.
(3) The conformational properties of these new TASPs are now under investigation, with special emphasis on the relationship between overall conformation and the nature of the topological template.
(4) In the context of a simplified diamond lattice model of a six-member, Greek key beta-barrel protein that is closely related in topology to plastocyanin, the nature of the folding and unfolding pathways have been investigated using dynamic Monte Carlo techniques.
(5) At the Second Scandinavian Congress on Image Analysis in 1981 Kohonen provided evidence that the map of signals has the same topological order as the map of reactions.
(6) Phylogenetic analysis of the aligned sequences by both phenetic and cladistic methods with H. perryi as an outgroup generated one best topology which pairs S. alpinus with S. malma as the most recently derived species, and pairs S. confluentus with S. leucomaenis.
(7) Then, a 'hyperstructure matrix' is generated, containing the unique topological relationship between every pair of regions.
(8) Linear DNA substrates in which pairing is topologically restricted to a paranemic joint also follow this relationship.
(9) The subgroups of carcinoma of the bladder, determined by topology, have markedly different long-term prognoses.
(10) The fluorescence properties of Hoechst 33342 (HO 33342) were examined with plasmid pBR322 in the supercoiled (Form I) or relaxed covalently closed circular (Form Io) conformation in order to determine whether qualitative or quantitative differences in fluorescence properties might provide an assay for topological states of DNA.
(11) An exhaustive search of all possible trees also supported this topology, although one haplotype had to be eliminated from this analysis to save computer time.
(12) This superfamily of proteins is predicted to share the topology of the seven transmembrane helices of bacteriorhodopsin (BR), even though no significant sequence homology had been identified.
(13) These data demonstrate the utility of this approach for determining membrane protein topology and extend potential applications to include at least some proteins not normally expressed in E. coli.
(14) The unique topology of the products indicates that resolvase fixes the sum of the number of supercoils between recombination sites at synapsis and the number of such supercoils lost or gained during strand exchange.
(15) Such explanations are possible because the relatively few structural proteins of the erythrocyte are regularly distributed over the entire cytoplasmic surface of the cell membrane and because the well-understood topological associations of these proteins seem to be stable in comparison with the time required for the cell to change shape.
(16) The objectives of the present investigations were to document a composite, new approach for the evaluation of the structure-function dependencies of proteins based on the analysis of the informational content of the primary amino acid sequence as well as the topological and functional regions of a protein.
(17) When the input topology is supercoiled, high levels of transcription are observed, whereas input relaxed DNA is transcribed to a much lower extent.
(18) It is believed that one or more basic residues at the extreme amino terminus of precursor proteins and the lack of a net positive charge immediately following the signal peptide act as topological determinants that promote the insertion of the signal peptide hydrophobic core into the cytoplasmic membrane of Escherichia coli cells with the correct orientation required to initiate the protein export process.
(19) We observe that the effect of osmotic shock is an elevation of superhelical tension; quantitative comparison with changes in plasmid linking number indicates that the alteration in DNA topology is all unconstrained.
(20) Anomalous correspondence most probably has its seat where the retinal topology is not exact, i.e., where the binocular receptive fields are very large and encompass the corpus callosum, such as in area 20 or 21.
