(9) The participants strongly preferred the experimental leaflets to the approved leaflets, both with respect to accessibility of the contents (overall preference 78.1% v 17.8%) and ease of understanding the contraindications of drug use (90.2% v 73.7%).
(10) Sixty days after 5,7-DHT administration, immunoreactive serotonin in the forebrain, particularly the suprachiasmatic nuclei and intergeniculate leaflets, was severely depleted in 16 animals, moderately depleted in four and only slightly affected in four.

(13) It was not related to a greater degree of dilatation of the tricuspid ring but to more severe septal and right ventricular infarction causing prolapse of the septal and posterior septal leaflets into the right atrium.
(14) The edge of the valve leaflet and the other 2 cusps were intact.
(15) The opening amplitude of the leaflet as well as the slope of the ejection fraction were not decreased.
(16) Changes in strain in the line of aortic valve leaflet attachment (aortic ring) were measured during the cardiac cycle by means of an inductive technique.
(17) Angiographic features felt to indicate valve tearing were present following 17 of 25 procedures and included increased excursion or straightening of leaflets, localized change in leaflet motion (flail leaflet), and the presence of an additional contrast jet through the valve.
(18) Furthermore, the long axis of the right and left atria was measured from the center of the apposed atrioventricular valve leaflets to the posterior atrial wall, and the sizes of the atrial chambers were defined using their widths at the prospective broadest points through the area of foramen ovale.
(19) One valve displayed a fixed outward eversion of the free margin of two leaflets.
(20) To date, 3-dimensional studies have demonstrated that the mitral valve is saddle-shaped in systole, so that apparent superior leaflet displacement in the mediolateral 4-chamber view, often seen in otherwise normal individuals, lies entirely within the bounds defined by the mitral annulus and occurs without leaflet distortion or actual displacement above the entire mitral valve.
Pinnule
Definition:
(n.) One of the small divisions of a decompound frond or leaf. See Illust. of Bipinnate leaf, under Bipinnate.
(n.) Any one of a series of small, slender organs, or parts, when arranged in rows so as to have a plumelike appearance; as, a pinnule of a gorgonia; the pinnules of a crinoid.
Example Sentences:
(1) Aminergic elements were revealed by glyoxylic acid-induced fluorescence in the branchial nerve, branchial ganglion, branchial vessels, and pinnules in both species.
(2) It was noted in the pinnules that there was a much higher concentration of dopamine than serotonin.
(3) The younger pinnules or tips of A. fiordensis are less than 3% diphenol by weight.
(4) Tactile stimulation of the pinnule evoked a two-component contractile reflex contraction due to activation of the peripheral nerve plexus.
(5) In semi-intact preparations, pinnule contractions and junctional transmissions were then measured during 3-s depolarized pulses to L7 (frequency range = 1-44 per 3-s interval).
(6) Isolated pinnules of the gill of Aplysia contract when dopamine (DA) is perfused through the bath.
(7) As Aplysia age, motor neuronal (L7) elicited gill-pinnule contractions are significantly decreased, as is transmission at pinnule junctions.
(8) A weak or moderate tactile stimulus to the mantle elicits gill contraction (gill-withdrawal reflex) as a component of a more extensive withdrawal response; a stimulus applied directly to the gill elicits a localized response of the gill pinnule (pinnule response).
(9) Peripheral pathways are necessary and sufficient for the pinnule response.
(10) The pinnule often shows irregular, spontaneous contractions which are blocked by high-Mg2+ seawater and 30 mM CoCl2.
