What's the difference between spherolithe and spherule?
Spherolithe
Definition:
Example Sentences:
(1) Anisotropic structures can be observed either at the periphery of the dendrites or isolated as small spheroliths.
(2) The initial stage is characterized by a periductally lymphocytic infiltration, ectasias of the ducts, and alteration of the secret in the duct lumens (spheroliths, microliths).
(3) It was found that admixtures of urea, creatinine, potassium and, possibly, sodium contained in the urine of patients initiate the formation of copper chloride crystals of different sizes, their shape changes, dendritic and spherolithic crystallization occurs.
(4) Laser microprobe mass analysis was applied to study the chemical composition of spheroliths in the Bowman's membrane of patients suffering from primary atypical bandkeratopathy.
(5) Characteristic congophilic laminated spheroliths are present within the cystic spaces.
Spherule
Definition:
(n.) A little sphere or spherical body; as, quicksilver, when poured upon a plane, divides itself into a great number of minute spherules.
Example Sentences:
(1) The intestinal cells are filled with concentric spherules, and the intestinal lumen is reduced.
(2) The egg cortex is enriched in two organelles, ectoplasmic spherules and associated structures, which are similar in appearance to nuage.
(3) Melanin synthesis in the myxomycete Physarum polycephalum occurs during sporulation but not during spherule formation.
(4) synaptic ribbon (SR) and synaptic spherule (SS) numbers, was explored in 6 different stocks and strains of laboratory rats, viz.
(5) Applying immunological and electron microscopical techniques it is shown that insulin is produced in specialized cells (spherulous cells).
(6) The lunar particles found in the sample include: (i) spherules, rotational ellipsoids, dumbbells, tear-drops, rings, and crescents which have (ii) diameters of 0.1 to 500 microns; (iii) budlike features on the particles; and (iv) chemical inhomogeneity (electron probe).
(7) Types II and VI collagen were not detected in collagenous spherules of salivary gland tumors.
(8) Special stains indicated that the spherules were collagen-rich, but also contained variable amounts of acidic mucin, PAS-positive, basement membrane-like material, and elastin.
