(17) Overall, there is structural and computational economy, or even parsimony.
(18) Thus, whereas a change in central MSH sensitivity may contribute to reduced fever in aged homeotherms, a reduction in central pyrogen receptors appears to be the most parsimonious explanation.
(19) Fourteen thioredoxin sequences were used to construct a minimal phylogenetic tree by using parsimony.

Tightness
Definition:
(n.) The quality or condition of being tight.
Example Sentences:
(1) Freshly isolated sarcoplasmic reticulum vesicles contain 0.05 mol of tightly bound ADP and 0.03 mol of tightly bound ATP per mol of Ca2+, Mg2+-ATPase (ATP phosphohydrolase, EC 3.6.1.3).
(2) The expression of the Pgp isoforms appears to be tightly regulated and, at least in some cells, under complex hormonal control.
(3) Whereas the tight junctions of endoneurial capillaries are known to prevent certain blood-borne substances from entering the endoneurium, it was not clear whether the permeability of the pulpal capillaries, which are distant from the nerve fibres, could affect the nerve fibre environment.
(4) The cells are predominantly monopolar, tightly packed, and are flattened at the outer border of the ring.
(5) These data indicate that topoisomerase I and RNA polymerase I are tightly complexed both in vivo and in vitro, and suggest a role for DNA topoisomerase I in the transcription of ribosomal genes.
(6) Immunofluorescence and immunoelectronmicroscopy experiments demonstrated that while tight junctions demarcate PAS-O distribution in confluent cultures, apical polarity could be established at low culture densities when cells could not form tight junctions with neighboring cells.
(7) Investigations have been made to determine the identity and binding characteristics of the pterins that are bound tightly to dihydrofolate reductases which are isolated from vertebrate sources by a well established procedure.
(8) At all times, a tight inverse correlation exists between ATP and IMP concentrations.
