(n.) A rhizopod. common in fresh water, capable of undergoing many changes of form at will. See Rhizopoda.
Example Sentences:
(1) An unprincipled coward with the backbone of an amoeba."
(2) Developing D. discoideum amoebae synthesize and secrete cAMP following the binding of cAMP to their surface cAMP receptor, a response called cAMP signaling.
(3) The relative amount of the crystals was measured in both amoeba strains on the basis of the integral extinction value.
(4) In amoeba cells the enzyme, like exo N-acetylglucosaminidase and acid phosphatase, is attached to the lysosomes, as it is sedimentable when homogenates are prepared in medium containing sucrose.
(5) Recent reports incriminating Acanthamoeba, a small free-living amoeba, wide-spread in environmental soils and waters, in acanthamoebic keratitis cases wearing soft contact lenses, drew attention to cleaning solutions for contact lenses.
(6) The amoeba, however, could not use yeasts, molds, or a green alga as a nutritional source.
(7) The drinking water was tested in chemical and bacteriological respects as well as on amoebas and rotaviruses.
(8) A new amoeba, isolated from well water in Gambia, West Africa, is described and named Phreatamoeba balamuthi n. g., n. sp.
(9) It was found that the uptake of this cation by the amoebae was fast in both species, conditions that modify the membrane potential (hyperpolarization and depolarization) produced changes in the fluorescence of the dye in agreement with its reported capability to detect variations in membrane potential.
(10) Alcian blue and Na+, both inducers of pinocytosis, differ in the manner with which they associate with the amoeba surface, suggesting the possibility of different pinocytosis-inducing sites on the amoeba surface.
(11) PHA-stimulated T-lymphocytes, depleted of T8-bearing cells by complement-mediated lysis, were unable to kill amoebae.
(12) Results show that the 3-D disc is mostly preceded by impressions of elastic amoeba-like deformations, whereas the 3-D egg is mostly preceded by the percept of a rotating flat ellipse.
(13) In contrast, incorporation by amoebae starving in suspension culture continued for 6-8 h. Similar patterns of [35S]sulphate incorporation were observed for two other strains of D. discoideum (strains AX2 and NC4) and for Polysphondylium violaceum.
(14) Focal contact sites are left behind on the glass surface ('footprints') when the amoeba moves away.
(15) Treatment during starvation of D. discoideum amoebae with micromolar amounts of A23187 causes an enhanced aggregation.
(16) Many trophozoite-target interfaces were outlined with a ring of polymerized amoeba actin, revealed by rhodamine-phalloidin staining of glutaraldehyde-fixed and Triton-X 100-extracted cells.
(17) Similar treatment of nonpathogenic amoebae had no effect on susceptibility to complement.
(18) An extracellular cyclic nucleotide phosphodiesterase was isolated from either growing cultures or aggregating amoebas of Dictyostelium discoideum.
(19) The establishment of amoebae leading to acute liver abscess was accompanied by significantly reduced levels of antibodies to the plasma membrane (PM) protein of E. histolytica, reduced direct macrophage cytotoxicity, and reduced anti-PM antibody-mediated macrophage-dependent cytotoxicity to amoebic trophozoites.
(20) When developing cultures of Dictyostelium discoideum are disaggregated at any time prior to cell wall formation and challenged to reinitiate development, amoebae will progress through the original sequence of morphogenetic stages, but the second time through they will do so in roughly one-tenth the original time, a process known as 'rapid recapitulation'.
