(17) These findings indicate that the oxygen tension around the cathode was diminished in advance of the electrically stimulated callus formation.
(18) There is increased metabolism of glycosaminoglycan collagen synthesis, and transformation of fibrous and cartilaginous callus, combined with mineralization of the latter and intensified vascular invasion into bone.
(19) Bone union can be achieved under external fixation through different pathways, ranging from callus-free gap healing under a rigid neutralization configuration to direct-contact healing with periosteal new bone formation under axially dynamized stable fixation.
(20) We compare the gene activity in heterozygotes versus homozygotes, and show variation in activity between plants regenerated independently from the same transformed callus.

(n.) Sedge.
(n.) The gladen, and other species of Iris.
(n.) A castrated bull.
Example Sentences:

(4) The viral growth was not significantly affected by host polAts, seg, and groPC mutations.
(5) F-genote formation from seg Hfr stains is dependent on a functional recA gene, as F-genote formation was not seen with a seg-2, recA-1 Hfr.
(6) There were no significant differences in bioavailability of riboflavin and pyridoxine hydrochloride between the SEG formulation and the tablet albeit a trend toward consistent absorption was seen from the SEG formulation.
(7) The inactivation constant of the fast time course reaction was 0.1 seg-1.
(8) Removal of the brain from a CNS isolated prior to ecdysteroid exposure resulted in the appearance of spontaneous bursts, which were abolished by removing the suboesophageal ganglion (SEG).
(9) The circuitry responsible for activating these motor pattern generators is associated with the SEG, and is under the control of the brain.
(10) We concluded that (1) at presentation, the specific glomerular lesion in severe lupus GN cannot be predicted on clinical or serological criteria alone; (2) on the basis of morbidity and mortality, cases with all three morphologic variants should be classified as severe lupus GN; and (3) patients with MGN + PGN appear to experience more adverse outcomes than patients with SEG or diffuse GN.
(11) Original values and ratio of the first day p. p. (T = 6.91%: Seg = 41.13%) changed in the average value of T = 1.93%: Seg = 43.96% during the whole puerperium.
