(19) Gingival fluid was sampled from the orifices of the gingival crevices in five male subjects with clinically healthy gingiva.
(20) These bands can be assigned to modes which include strong contributions of vibrations largely localized in the propionate-carrying pyrrole rings A and D. This indicates structural differences in the deeper part of the heme crevice, remote from the mutation site.
Interstice
Definition:
(n.) That which intervenes between one thing and another; especially, a space between things closely set, or between the parts which compose a body; a narrow chink; a crack; a crevice; a hole; an interval; as, the interstices of a wall.
(n.) An interval of time; specifically (R. C. Ch.), in the plural, the intervals which the canon law requires between the reception of the various degrees of orders.
Example Sentences:

(5) The potential consequences of vascular damage are described as well as the importance of pancreatic lymphatics in the transport of the escaped enzymes from the interstices.
(6) It was also suggested that the interstices of the collagen fibers in the myocardial wall constituted the lymphatic ducts outside the blood vessels and that the MAO activity in serum determined by the method in which tryptamine hydrochloride was used as substrate might indicate the grade of fibrosis of the myocardial tissue in the infarcted areas.
(7) Mesh interstices epithelialized over the surface of the full-thickness wound (control sites) or over the surface of Dermagraft (experimental sites).
