(13) Other than failing to get a goal, I couldn’t ask for anything more.” From Lambert’s perspective there was an element of misfortune about the first and third goals, with Willian benefitting from handy ricochets on both occasions.
(14) These data indicate that the sfrB gene product is a regulatory element, since the single gene product elicits the expression of genes for many products for F expression and lipopolysaccharide synthesis.
(15) Therefore, a hormonal regulatory element can discriminate among closely related transcription start sites.
(16) The safe motherhood initiative demands an intersectoral, collaborative approach to gynecology, family planning, and child health in which midwifery is the key element.
(17) The 500-bp element arose by duplication of one half of a 180-bp ancestor and insertion of a foreign segment between the two duplicated parts followed by amplification.

(19) The hypothesis that the standard acoustic startle habituation paradigm contains the elements of Pavlovian fear conditioning was tested.
(20) Autopsy revealed a primary intimal sarcoma with osteogenic elements arising in the posterior leaflet of the pulmonary valve and obstructing the main pulmonary artery and its right branch.
(n.) One who selects.
(1) Using consumer survey data from the Missouri Managed Health Care Project, we examined characteristics and use experiences of assignees compared with selectors.
(2) The use of this selector creates a possibility of reducing the increase in the synchronizing pulse with respect to the channel pulses and eliminating tuning the transmitter's modulator and receiver's selector to each other.
(3) The optimum threshold values for this selector are as follows: 12 ms in the rate and 14 ms in the duration.
(4) The members of the main feeding categories (Hofmann, Stewart 1972): concentrate selector, roughage eater and intermediate feeder did not differ much in the ultrastructure of the fundic stomach epithelium but showed greater differences with respect to the height and shape of the glandular tubules and the arrangement of the epithelial cell types.
(5) The DNaseI footprint of this protein complex with the enhancer overlapped a sequence, AGGAGGA, found within the binding site for a protein that interacts with the chicken beta globin promoter and enhancer, termed the stage selector element.
(6) These results support the selector gene model of development (Garcia-Bellido, 1975) and emphasize that collaboration between polyclones is important in pattern formation.
(7) But the East Ender will not compete over the one lap in Daegu, while the runner-up – Shana Cox – only qualifies for a British passport from November of this year and so all three British places are up for grabs as the selectors meet to decide who will travel to South Korea this summer.
(8) In Drosophila embryos, anterior-posterior positional identities are set and maintained by the expression boundaries of homeotic selector genes.
(9) Use of the full panel to grade all abstracts was very expensive, but it could be replaced, without unacceptable injustice, by dividing the work randomly among groups of three selectors.
(10) Using the selector method on serial plastic sections, we determine the number of epithelial or interstitial cells per volume (Nv) of total epithelium or interstitium.
(11) So this element is likely to be a target of homeotic genes, which would define the beta 3 tubulin gene as a realisator gene under the control of selector genes.
(12) A monitor useful for checks of the energy selector scale of medical electron accelerators was developed and tested.
(13) Indeed, c-Jun and c-Fos served as selectors of hormone responsiveness: the composite GRE was inactive in the absence of c-Jun, whereas it conferred a positive glucocorticoid effect in the presence of c-Jun, and a negative glucocorticoid effect in the presence of c-Jun and relatively high levels of c-Fos.
