What's the difference between bathybius and protoplasm?
Bathybius
Definition:
(n.) A name given by Prof. Huxley to a gelatinous substance found in mud dredged from the Atlantic and preserved in alcohol. He supposed that it was free living protoplasm, covering a large part of the ocean bed. It is now known that the substance is of chemical, not of organic, origin.
Example Sentences:
(1) n. from the synaphobranchid eel Synaphobranchus bathybius differs from N. glandulosum and N. polymixiae, the most similar species, because conspicuous glandular cells envelop the esophagus and pharynx, others about the genital atrium occur in elongated sacs, epithelium is lacking at the cecal bifurcation, and the cirrus sac is straight.
Protoplasm
Definition:
(n.) The viscid and more or less granular material of vegetable and animal cells, possessed of vital properties by which the processes of nutrition, secretion, and growth go forward; the so-called " physical basis of life;" the original cell substance, cytoplasm, cytoblastema, bioplasm sarcode, etc.
Example Sentences:
(1) Fixation with buffered glutaraldehyde resulted in higher counts (P less than 0.01) of proximal protoplasmic droplets (2.47, 1.03, 0.67, and 1.43%, respectively, for glutaraldehyde, Hancock's, Blom's, and formol saline procedures).
(2) Small, diffusely GJP-IR cells were identified ultrastructurally as protoplasmic and fibrous astrocytes.
(3) Protoplasmic cylinders contained within such granules frequently were devoid of cell envelopes.
(4) The infected cells treated by this method showed light green fluorescence of the protoplasm, with a dark nucleus, while the intact cells had tile-red cytoplasm.
(5) That T-tubules isolated by disruption of triad junctions are constrained to have the protoplasmic (P) face uniformly exposed was experimentally confirmed.
(6) The morphological change of cerebral cortex astrocytes from protoplasmic to glial fibrillary acidic protein (GFAP)-containing cells is induced by injury.
(7) Pretreatment of mice by intravenous injection with killed Listeria provided neither delayed-type hypersensitivity to Listeria protoplasm nor protection against Listeria infection.
(8) The greatest motion of protoplasmic droplets was recorded in the caput epididymidis, although the migration of droplets from the proximal section of the connective part of the flagellum towards the distal parts could also be observed as far as in the cauda epididymidis in both animals.
(9) Thus staining techniques that have a propensity for the glial filaments such as antisera to glial fibrillary acidic protein and the gold-chloride method provide only a skeletal outline of the major processes of the protoplasmic astrocyte.
(10) Within this context, we would like to present a case discussion regarding a 27-month-old boy with a hypothalamic-midbrain protoplasmic glioma treated with primary chemotherapy after surgical biopsy and pathologic documentation.
(11) The toxin appears to be protoplasmic and is released into the surrounding environment upon autolysis of the cells.
(12) To improve the definitions, eliminate overlapping diagnostic categories, and sharpen the fuzzy boundaries that contribute substantially to limited reproducibility, we suggest: (1) the categories of astrocytoma nos, fibrillary astrocytoma, and protoplasmic astrocytoma be collapsed into a single category of astrocytoma; (2) the diagnostic category of desmoplastic medulloblastoma be combined with medulloblastoma; and (3) the criteria for anaplasia should be further refined to include quantification of critical histologic features, e.g., agreed upon operational definitions for amount of cell density, number of mitoses and pleomorphism for anaplastic astrocytoma and anaplastic ependymoma.
(13) They mainly concentrate on the membrane protoplasmic surface.
(14) The incompatibility reaction when vegetative or sexual R and V cells fuse is asymmetric: it is induced only in the R protoplasm.
(15) The intramembranous particles in the protoplasmic face of fractured membranes obtained from fresh cells incubated with 1 mM of Ca2+ were more scattered and their density was lower than in control cells.
(16) Morphometric analysis of the outgrowth zone revealed a statistically significant decrease in the incidence of fibroblastic-reactive microglial cells (from 12 to 0%), and a significant increase in the incidence of protoplasmic astrocytic-epithelial cells (from 82 to 96%), for AraC-treated explants compared to controls.
(17) Periplasmic bodies were most prevalent in the regions of the bud scars and were often accommodated within large invaginations in the protoplasmic membrane.
(18) However, electron microscopic immunocytochemical analysis of NG2 immunoreactive cells revealed a cell morphology consistent with that of protoplasmic astrocytes.
(19) (2) It has been shown that in protoplasmic drops the endoplasm-ectoplasm transformation is accompanied by an actin polymerization from the non-filamentous state to F-actin.
(20) These studies are based upon the observation that a number of experimental maneuvers can alter tissue permeability to water, but do not change the number of particle aggregates observed on the protoplasmic face of the granular cell's luminal membrane with freeze-fracture electron microscopy.
