(19) We have investigated the effect of methimazole (MMI) on cell-mediated immunity and ascertained the mechanisms of immunosuppression produced by the drug.
(20) Apparently, the irradiation with visible light of a low intensity creates an additional proton gradient and thus stimulates a new replication and division cycle in the population of cells whose membranes do not have delta pH necessary for the initiation of these processes.
Zooid
Definition:
(a.) Pertaining to, or resembling, an animal.
(n.) An organic body or cell having locomotion, as a spermatic cell or spermatozooid.
(n.) An animal in one of its inferior stages of development, as one of the intermediate forms in alternate generation.
(n.) One of the individual animals in a composite group, as of Anthozoa, Hydroidea, and Bryozoa; -- sometimes restricted to those individuals in which the mouth and digestive organs are not developed.
Example Sentences:
(1) 5-HT antigenicity in the postpharyngeal commissure indicates the initiation of the development of a new zooid.
(2) At the onset of takeover (T = 3 hr), B3F12.9 immunostaining became diffuse or absent at the anterior end, which paralleled the axis of contraction of the dying zooid, whereas the posterior end retained its labeling integrity.
(3) The latter process is similar to the degeneration of old individuals, or zooids, that precedes maturation of each new generation of asexual buds.
(4) The rate of cell fission was retarded in colchicine-containing media, but nevertheless short-stalked colonies with apparently normal zooids were formed.
(5) Site-specific reactions were also observed in larval tail muscle and the siphon muscles of postmetamorphic zooids.
(6) Here we describe a monoclonal antibody (B3F12.9) that recognizes a novel 57 Kd polypeptide (under reducing conditions) localized to the perivisceral extracellular matrix (PVEM) of buds and zooids, as well as blood cells of Botryllus by immunofluorescence and immunogold labeling of tissue sections.

(11) The colonial tunicate Botryllus schlosseri undergoes cyclic blastogenesis where feeding zooids are senescened and resorbed and a new generation of zooids takes over the colony.
(12) They form the probable route of transfer of yolk from the zooids to the dormant bud.
(13) These findings indicate that takeover is a dynamic process in which extracellular matrix breakdown proceeds in a polarized fashion, beginning at the anterior end of each zooid and gradually propagating toward the posterior end.
