(a.) Resembling an amoeba; amoeba-shaped; changing in shape like an amoeba.
Example Sentences:
(1) In one case of human malaria imported from Gabon, abnormal forms of Plasmodium vivax are described; severe multiple infections of the host erythrocytes are noticed (up to 6 amoeboid trophozoites in a single red blood cell).
(2) The present investigation used a novel method of labelling the rat supraventricular amoeboid microglia with an enduring fluorescent marker, rhodamine B isothiocyanate, introduced intraperitoneally.
(3) The different modes of movement observed in different types of amoeboid cells could result from the site, rate, and extent of actin transformation followed in some regions by contractions.
(4) The primordial germ cells appear to enter these cell cords by an amoeboid type of movement.
(5) The results suggest that in the postnatal rats, the HRP passed through the endothelial lining of the blood vessels and was then ingested by the amoeboid microglial cells.
(6) Two of these forms corresponded to the amoeboid and ramified microglia; the amoeboid form stained intensely for esterase activity and ramified cells possessed Fc receptors.
(7) Immature gametocytes were highly amoeboid and showed extensive vacuolisation or attenuation of the cytoplasm.
(8) These results indicate that actin polymerization may constitute one of the driving forces for pseudopod extension in amoeboid cells and that nucleation sites regulating polymerization are under the control of chemotaxis receptors.
(9) Both signals may be part of a normal pseudopodium autoactivation and inhibition system responsible for amoeboid morphology and motility.
(10) The increase of the number of the follicular cells which join the oocytes might contribute to stop the amoeboid movements.
(11) It was concluded from this study that the round amoeboid microglial cells differentiate to become the ramified microglia with age.
(12) The amoeboid microglial cells in the cysts were probably derived from the extravasated blood monocytes in response to the physical damage ensuing during the formation of the cysts.
(13) The unexpected recognition of amoeboid microglia by antibodies in Alzheimer's disease-cerebrospinal fluid is particularly interesting since these cells proliferate in response to nervous system disease and also engulf debris.
(14) The reduction of flagella (cilia) is occurring in different taxa independent of the transition of protists from the flagellate type of locomotion to the amoeboid, gliding of metabolizing ones, and in the number of metazoan cells.
(15) The remaining part contained the organelles normally seen in T. vag.. Endocytotic cell activity of amoeboid T. vag.
(16) Thus, it is possible to generalize from the present and earlier findings that amoeboid microglial cells are normal cellular constituents in the maturing central nervous system and their temporary existence in the neonatal stage indicates the necessity of these cells for subsequent maturation of the nervous tissue.
(17) Fifty-one patients were treated in a dual-centre, double-blind comparison of acyclovir and adenine arabinoside in herpetic amoeboid (geographic) corneal ulceration.
(18) Amoeboid chemotaxis involves a regulated increase in actin nucleation activity that is correlated with an increase in actin polymerization occurring seconds after chemotactic stimulation (Carson, M., Weber, A., and Zigmond, S. H. (1986) J.
(19) Some of the PGCs in contrast, did not enter the blood vessels but remained in the tissue (mesenchyme) of the embryo proper (tissue PGCs) and possessed pseudopodial processes, suggesting their migration by means of amoeboid movements.
(20) separation of hyaline plasma from granular plasma and changes in both the protoplasmic streaming pattern and locomotory activity of the cells, are discussed in terms of a general understanding of amoeboid movement.
Rhizopod
Definition:
(n.) One of the Rhizopoda.
Example Sentences:
(1) All representatives of the broad chromophyte assemblage were positive while all rhizopods were negative.
