What's the difference between hemispheroid and spheroid?
Hemispheroid
Definition:
(n.) A half of a spheroid.
Example Sentences:
(1) As the hemispheroid and multilayer islands were the intermediate form between monolayer and floating spheroids, the glycosaminoglycan moieties of the proteoglycan fraction were thought to participate in the formation of spheroid.
(2) Cells seeded in dishes coated with these defined glycosaminoglycans and heparin assembled to form hemispheroids and multilayer islands, but not floating spheroids, within 72 h of culture.
(3) Using a double hemispheroid model, volumes of CS and AS were separately estimated by a modified area-length method.
(4) Sacs were usually either hemispheroids or shallow truncated cones.
(5) Those complexes are basically similar throughout the receptor, except that a hemispheroidal gap junction between a supporting cell and adjacent hair cell was noted in several instances.
(6) Secondary brain damage in this model was characterized by progressive cortical hypoperfusion, edema, and BBB disruption in the vicinity of the hemispheroid lesion occurring acutely after injury.
(7) The methods used for these measurements were validated by measuring the current densities induced in a grounded hemisphere and in a grounded prolate hemispheroid; agreement between measurement and theory was good.
(8) Dermatan sulfate had a stronger ability to induce hemispheroids than heparan sulfate or heparin.
Spheroid
Definition:
(n.) A body or figure approaching to a sphere, but not perfectly spherical; esp., a solid generated by the revolution of an ellipse about one of its axes.
Example Sentences:
(1) Microelectrodes were used to measure the oxygen tension (PO2) profile within individual spheroids at different stages of growth.
(2) Aside from typical nuclear spheroids, irregularly shaped nuclei were frequently seen, associated with increased nuclear folds, transitional stages between nuclear folds and nuclear spheroids were also present.
(3) The nuclei in these typical onocytes appeared oval or spheroid.
(4) The tumor cells of these melanomas are characterized by spheroidal melanosomes and containing pheomelanins.
(5) This is a clinical, histopathological and electron microscopical study on the spheroidal degeneration of the cornea by means of 48 histologically verified cases.
(6) Our results show the feasibility of back-extrapolating multicellular tumour spheroid growth curves to obtain survival estimates that can be applied to establish sublethal damage repair capacity.
(7) HCG, E2 and P4 were secreted into the culture medium throughout the entire culture period, in proportion to spheroid size.
(8) In addition, it was observed that the higher resistance of the V79 spheroid cells than the monolayers to gamma-irradiation is not diminished in the pion peak, suggesting that the underlying phenomenon of intercellular communication influences cell survival even after high-LET irradiation.
(9) Under the 3-dimensional geometry of the spheroid system, there was, however, generally a more extensive ECM.
(10) The spheroids grew exponentially with a volume-doubling time of approximately 24 h up to a diameter of approximately 580 microns and then the growth rate tapered off, more for spheroids grown at the low than at the high oxygen tension.
(11) The cytotoxicity of doxorubicin (DX), 4'-O-methyl-DX (MET-DX), 4'-deoxy DX (DEO-DX), 4'-deoxy-4'-iodo-DX (IODO-DX), daunorubicin (DNR)and 4-demethoxy-DNR (DM-DNR) on LoVo cells cultured as a monolayer (in exponential and stationary phases of growth) and as spheroids, are evaluated following 1-h exposure to the drugs.
(12) Under conditions of severe hypoxia (< 0.01% O2), 2 h of pretreatment or 18 h of simultaneous treatment with SR 4233 did not significantly enhance the effectiveness of 131I-NR-LU-10 in spheroids.
(13) The reported prevalence and severity of primary spheroidal degeneration in Labrador and nothern Newfoundland is based on a survey of 929 patients.
(14) Apparently the latter represented conglomerates of adherent spheroid elements that resembled somewhat "large bodies" of L-forms.
(15) The results of immunotitration and immunodiffusion experiments and of the sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis of immunoprecipitates revealed: (i) a high degree of immunochemical identity of this enzyme only within the family Enterobacteriaceae; (ii) intermediate-to-weak cross-reaction with the phenylalanyl-tRNA ligases from Pseudomonadaceae, Rhodopseudomonas spheroides, and Bacillus stearothermophilus; (iii) no detectable cross-reaction (with the methods employed) with the enzymes from several gram-positive organisms, Euglena gracilis, and several fungi.
(16) Histological alterations included nerve fibre swelling and degeneration, occasional spheroids, astrocytic gliosis, increased macrophage activity and increased perivascular collagen.
(17) The photosynthetically-incompetent mutant V-2 of Rhodopseudomonas spheroides which is incapable of synthesising bacteriochlorophyll was grown aerobically under conditions of both high and low aeration.
(18) Transplanted spheroids continued to express the growth inhibitory activity.
(19) The outer-layer cells of spheroids and fed plateau monolayers peaked at a similar density; the majority of middle-layer cells banded close to unfed plateau and exponential hypoxic monolayers, while most inner-layer cells banded where fed or unfed plateau hypoxic monolayer peaked in density.
(20) Survival of spheroid and monolayer cells after hypertonic NaCl treatment was identical.
