(v. t.) To thrust forward; to drive or force along.
(v. t.) To thrust out, as through a narrow orifice or from confinement; to cause to come forth.
(v. i.) To shoot out or forth; to be thrust forward; to extend beyond a limit; to project.
Example Sentences:
(1) Here we present images of polydeoxyadenylate molecules aligned in parallel, with their bases lying flat on a surface of highly oriented pyrolytic graphite and with their charged phosphodiester backbones protruding upwards.
(2) As a basis for the discussion a possible structure for the DNA complex of the phenylated neutral red is considered in which the extra phenyl ring at N-5 of the phenazinium system, protrudes into the large groove of the DNA helix while the tricyclic part of the ligand is inserted between the DNA base-pairs.
(3) Since deglycosylation decreases the frictional ratio of thyroxine binding globulin, it is concluded that, although sialic acid and other sugar residues are in contact with the protein surface, the hydrated carbohydrate chains protrude partially into the solvent.
(4) There are several known enzymes recognizing the same sequence, although the prototype NarI and isoschizomers NdaI and NunII cleave the substrate to produce 5'-protruding ends, whereas cleavage with isoschizomer BbeI results in 3'-protruding ends.
(5) Of 193 patients suffering from peptic ulcer bleeding identified by emergency gastrointestinoscopy, 52 patients were found to have bleeding gastric ulcer (spurt 5, active oozing 9, fresh clot 11, black clot 17, protruding vessel 4, and clear base without stigmata 6); the other 141 had bleeding duodenal ulcer (spurt 5, active oozing 26, fresh clot 43, black clot 23, protruding vessel 15, and clear base without stigmata 31).
(6) The most frequently registered defects were: os tympanicum (smaller): 23%, os tympanicum (missing): 23%; missing tail: 7%; protruding tongue (15%); none of these defects were seen in the control fetuses.
(7) Light microscopic studies indicate it has an ellipsoidal centre from which catalase-positive filamentous or rod-like processes protrude along its major axis; hence, it is called a phi body.
(8) Numerous long irregular microvilli which are protruded from the supporting cells into the mucous film covering the olfactory epithelium contain no axial filaments.
(9) Comparison of posterior airway space was evaluated radiographically on patients with sleep apnea in a mandibular reposed position vs. a mandibular protruded position.
(10) Moreover, some cells protruded cell processes toward the neighboring cells through the extracellular matrix.
(11) In 20, the 'restrictive' tissue simultaneously protruded into the right atrium and ventricle; only in 12 did it extend exclusively into the right ventricle.
(12) But a missing nucleotide (responsible for one unpaired nucleotide protruding at the 3' or 5' end of the complementary strand) does not stop ligation of the shorter oligodeoxynucleotides between independent duplexes.
(13) Astrocyte endfeet of the GLM became irregular in contour, protruding in a fern-leaf fashion into the pial connective tissue.
(14) This strand forms a protruding 3' over-hang at the chromosomal terminus in three different eukaryotes analyzed.
(15) These included non-union at the trochanteric fracture, protruding pin, partial destruction of the femoral head, subcapital fracture of the femoral neck, and avascular necrosis of the femoral head.
(16) The block was produced by a large fragment of bone which had broken off the inferior end plate of the body of L4 and was protruding into the spinal canal.
(17) By transmission electron microscopy, discontinuity of the basal lamina (of the marginal glia) was found, and some tumor cells were found to have protruded their processes into the spinal cord parenchyma.
(18) An ultrastructural study found not only round, but also elongated and drumstick-shaped alpha-granules and rod-like structures protruding from round alpha-granules.
(19) Through combination with a spherical disc face perpendicular to the axis of rotation, which protrudes only slightly from the hemispherical catheter tip, with a maximum at the center and minimum at the lateral borders, the lathing head has only a slight risk of perforation and no undesired sheering forces (Figures 2a to 2d).
(20) A novel concentric design of double-barrelled Ca2+-selective microelectrode, with an inner pipette tip that protrudes beyond an outer one, has recently been developed and is described.
