(16) Both the beta 2-adrenoceptor agonist, procaterol (0.1 nM to 3 nM) and theophylline (100 nM to 1 mM) concentration-dependently reduced EFS-induced NANC contractions without significant effect on SP (1 microM)-induced contractions.
(17) Patients with hyperdiploid (47 to 50) ALL treated in a contemporary program of multiagent chemotherapy had a significantly better outcome than did those in an earlier study using less intensive therapy (4-year EFS = 75% [95% confidence interval, 55% to 86%] v 41% [22% to 59%]; P = .006 by the logrank test).
(18) These changes in EF were accompanied by the development of wall motion abnormalities, which occurred in segments of myocardium that were supplied by coronary arteries with angiographic CAD (more than 50% diameter narrowing).
(19) A central region in the primary structure of IF2 shows extensive sequence homology with a number of GDP-binding proteins and especially with the G-domain of elongation factor Tu (EF-Tu).
(20) (2) The four EF hands are arranged in two pairs with overall symmetry, 222.
Flipping
Definition:
(p. pr. & vb. n.) of Flip
Example Sentences:

(2) After 2 weeks of chronic exposure to 75 mM EtOH, crayfish showed behavioral tolerance as measured by a decrease in righting time and an increase in tail-flip escape behavior to control levels.
(3) The future prospects include shorter imaging times owing to fast-imaging sequences (short T1 with partial flip angle).
(4) 3) Just as lipids do not flip-flop, proteins do not rotate across the membrane.
(5) Two fast magnetic resonance (MR) imaging techniques, advanced Fourier and partial-flip imaging, were used at 0.35 T to examine 21 patients with suspected intracranial lesions; the results were quantitatively compared with a conventional spin-echo study.
(6) The presence of the flip-flop phenomenon in an I-131 Hippuran renal study suggests the existence of some degree of collecting system obstruction that has persisted long enough to result in renal parenchymal damage.

(8) For MR angiography 2D inflow (multiple-single-slice-technique, TR 40 ms, TE 14 ms, flip angle 60 degrees) and flow-adjusted-gradient-sequences (TR 24 ms, TE 10 ms, flip angle 60 degrees) were performed.
(9) Telomeres were generated from both arms of the substrate with equal efficiency, and contained the characteristic "flip" and "flop" sequence inversions observed in vivo.
(10) Does this count as campaigning?” “When was the last time you flipped a steak?” “What does it feel like to be in Iowa?” “Can you bring the reporters some meat?” “Are you running, Hillary,” one reporter shouted, finally, “from us?” Then Bill and Hillary disappeared around the corner; three quarters of the media scrum vanished, deflated.
(11) This value is similar to that obtained for the transbilayer "flip-flop" of phosphatidylcholine molecules in a similar system (Kornberg and McConnell, 1971).
(12) No "flips" to the opposite puckering for this ring were found in the simulations starting from the global minimum, although such a transition was observed for a trajectory initiated with one of the higher local minimum energy conformations.
