coli is a rod-shaped cell with a flagellum and macrophage has an amoeba-like shape with pseudopods, and the shape of the motionless state of these cells is not described by a circle.
During phagocytosis, the concentration of PI(4,5)[P.sub.2] increases in the pseudopods that form the phagocytic cup but then decreases abruptly [83].
Trophozoites showed very active movement, with wide pseudopods of rapid formation.
Ultrastructurally apical pseudopods and microvilli were commonly observed.
One of the cellular motors causes the cell membrane, the flexible envelope encasing all cells, to bulge out by forming so-called pseudopods. "In this instance, cell locomotion is driven by the localised growth of a dynamic protein scaffold pushing against the cell membrane from the inside," says Dr Tyson, continuing, "Cells employ complex regulation, linked to environmental sensing, to make pseudopods highly accurate steering devices, which are of limited power though." The second motor entails faster, pressure-driven protrusions in form of cellular blebs.
Atypical lymphocyte morphology, including pseudopods, split nuclei, and cytoplasmic granules, was observed in 5% of the birds.
Testate amoebae are protists whose protoplasm is inserted into a test (shell) with an oral aperture through which the pseudopods emerge during locomotion or feeding (Smith et al., 2008).
Platelet starts to change its shape by the formation of pseudopods when intracellular [Ca.sup.2+] concentration exceeds a specific threshold.
Forams are abundant in present-day ocean sediments, where they use fingerlike extensions called pseudopods to engulf prey and to explore their surroundings.
The commonly reported mechanisms are decreased life span of platelets due to immunological and non-immunological mechanisms, elevated macrophage colony stimulating factors causing platelet destruction; ultra structural changes like centralization of dense granules, glycogen depletion, formation of pseudopods, and micro aggregation; consumption by diffused intravascular coagulation (DIC) host oxidative stress through oxidization of membrane lipids causing changes in fluidity and permeability of the cell membrane and its effect on fragility (2,3).
Positive allergic reaction was defined as wheal with pseudopods within 5 minutes of injection, which persisted for at least 20 minutes, and was accompanied by localized itching.
Responding to this question, Richard Rorty argues that our Western bourgeois liberal culture "is a form of life which is constantly extending pseudopods and adapting itself to what it encounters.
We see these movements' echoes, too, in lamps of the late '60s--electrified pseudopods with feminine mouths--and in her early-'70s "desserts," cast polyester-resin breasts in Day-Glo colors, arrayed like sorbets on serving dishes.
Findings of dysplasia include 1 or more of the following: abundant megaloblastoid forms, nuclear budding, bizarre nuclear shapes, multinucleation, foamy cytoplasmic vacuoles, or cytoplasmic pseudopods (Figure 2, A and B).
Overall, these results indicated that the presumptive esophagus muscle cells derived from the visceral side of the coelomic pouch formed pseudopods and migrated to the esophagus.
