(16) In experiment I, females were obtained in the fall, subjected to an artificial dormancy period, and placed on warm, summer-like conditions in the laboratory.
(17) Spreading out the potential for hypopus completion over time is adaptive, since a pool of hypopodes with prolonged and staggered dormancies serves to spread the risk of emergence of tritonymphs over extended periods of time; it buffers the population against sudden drought to which all other stages of the life-cycle succumb.
(18) By reducing metabolic rate by a factor ranging from 5 to 100 fold or more, animals gain a comparable extension of survival time that can support months or even years of dormancy.
(19) The results obtained do not support a scheme of sequential expression of genes during the emergence from dormancy as a counterpart of the sequence of the corresponding genes along the chromosome.
(20) This is suggestive of hormonal interplay in dormancy release by cold-treatment in pear embryos.
Quiescence
Definition:
(n.) Alt. of Quiescency
Example Sentences:
(1) The latter group received progesterone to permit blastocysts and the dissected fragments to enter into quiescence, prior to injection of oestradiol to induce implantation.
(2) Two of the antisense-fos clones grew in a density-dependent manner, exhibiting both a flat morphology and a quiescence in low serum medium unlike the sense-fos controls.
(3) No significant difference between patients with IgA nephropathy in clinical quiescence and the control subjects was demonstrated.
(4) These analyses unmasked unique attributes of spontaneous LH secretory events, which were represented as delimited momentary augmentations in endogenous LH secretory rates interspersed among intervals of relative secretory quiescence.
(5) When compared with internal monitoring, the external monitor detected 90.8% of uterine contractions with a specificity for uterine quiescence of 98.1%.
(6) The data support the hypothesis that malignant cells can exist in a state of relative quiescence for extended periods.
(7) The arrested cells showed reduced levels of actin synthesis and the turning-off process in the synthesis of actin was found to be relatively slow as the cells entered into quiescence.
(8) The Syrian hamster is being used as an experimental aging model to investigate the intrinsic developmental program of dermal fibroblasts in vivo (proliferation, extracellular matrix (ECM) production, quiescence, and reactivation during wound repair) in order to determine whether the in vivo differentiation program and mature function of these cells is related to their in vitro proliferation and senescence pattern.
(9) After an initial quiescence period (growth arrest), target cells were exposed to plasma derived serum (PDS) from 4 experimental groups: young stimulated rats; young sham-operated controls; aged stimulated rats and aged sham-operated controls, at PDS concentrations of 2.5% and 5.0% and counted at days 2 and 5.
(10) Methionine-enkephalin (Met-Enk) and dynorphin were injected intra-arterially into the distal stomach and small intestine of the anesthetized dog during quiescence and phasic activity initiated by field stimulation or intra-arterially administered motilin.
(11) Migrating motor complexes and a low percentage of time of quiescence were noted on both recordings.
(12) Thus mesotocin is unlikely to act as a systemic luteostatic agent during seasonal quiescence.
(13) Interventions such as quiescence, manganese and acidosis reduce myocardial contractility and increase the size of the extracellular space.
